Opis:
Mastitis is the most important disease of dairy cows, affecting the major economic losses of milk producers and the dairy industry around the world. In the work on the basis of data from the laboratory dairy plants analyzed the occurrence of microorganisms causing mastitis. Based on microbiological studies, 1462 milk samples taken from quarters of the cows' udders showed that the most common cause of inflammation was Streptococcus agalactiae, whose strains occurred in 27.77% of mastitis cows. In 18.13% of cows mastitis was caused by Staphylococcus aureus, 14.91% by Eschericha Coli, 8.55% by Streptococcus uberis, and 8.82% did not show bacterial growth during microbiological tests. In order to reduce the occurrence of mastitis, appropriate hygiene should be followed during milking of cows and, in the case of disease, cows udder milk should be tested to identify the microorganism causing inflammation and prepare appropriate antibiotic therapy.

Opis:
Udder inflammations are one of the most common diseases of high-yielding dairy cows that cause high economic losses and have negative influence on milk technological value. Nowadays, pathogens involved in the inflammation process present lower susceptibility to antibiotics and around 90% of mastitis cases is caused by environmental bacteria. This situation forces researchers for seeking new solutions in mastitis prevention and treatment. The aim of this paper was to describe bacteria, fungi and algae are most common reasons of mastitis in dairy cows.

Opis:
Copper deficiency is a common homeostatic disorder in dairy cattle farms in Poland. A simultaneous decrease in blood copper and iron concentrations is very rarely diagnosed and described in dairy cows. Copper is necessary for the mobilization of iron from the liver and its transport to bone marrow, where it is used for erythropoiesis. The aim of the study was to observe changes in haematological parameters in cows, resulting from copper deficiency or simultaneous deficiency of copper and iron, in comparison with animals from the same herds in which no deficiencies of these micronutrients were found. The study was conducted on 56 cows of the HF breed, aged from 3 to 6 years, from 3 dairy farms. The animals selected for the study were divided into three groups, two deficiency groups and one control group – without deficiency. Group I comprised animals with reduced concentration of copper in the serum, while group II comprised animals with low copper and iron concentrations. Group III comprised healthy cows without clinical symptoms and mineral deficiency. In both deficiency groups, the one characterized by a low concentration of copper, as well as the one with low concentrations of copper and iron, a reduction in red blood cell parameters, which was statistically significant versus the control group, was observed. In the examined animals, normocytic normochromic anaemia was found in group I, while normocytic hypochromic anaemia was diagnosed in group II. Cows with simultaneous Cu and Fe deficiency have worse milk yield results and they are more often culled from the herd. It is not clear why only some animals in a herd develop simultaneous deficiency of these micronutrients.

Opis:
Mastitis is an increasing problem in dairy farms and in the dairy industry. The paper presents changes in susceptibility of strains of bacteria isolated from quarter milk cows from mastitis in 2011, 2012, 2013, 2014, 2015 in the Factory Laboratory of Dairy Cooperative in south-eastern Poland. In total, 3409 strains of staphylococci, 2774 strains of streptococci and 423 strains of E. coli were isolated in these years. Susceptibility to antibiotics was examined by the disc diffusion method on Mueller-Hinton base. On the basis of the research it can be concluded that the highest sensitivity of staphylococci in all study periods is found for cefguin (from 91.2% to 96.1%) and cefapirin (92.2% to 96.2%), and the smallest for tetracycline (18 %), streptomycin (11.9%) and amoxicillin (9.3%). The highest sensitivity of bacteria from the Streptococcus family are cefapirin (97%), cefquinome (96.1%), amoxycycline (95.6%) and cefalexin (89.9%) on average in all years of research. The highest resistance was found for neomycin and streptomycin. They show that during the period under study over 90% of Escherichia coli were sensitive to streptomycin. Sensitivity at the level of 70%-80% was noted for amoxicillin, neomycin and cefapirin. The highest resistance of E. coli bacilli evolved for cefallaxin and tetracycline. Accordingly, early diagnosis of a pathogenic pathogen, and then selecting the appropriate form of treatment, gives you the opportunity to minimize the loss of mastitis in dairy cows.

Opis:
This study aimed to identify bacterial pathogens in milk samples from dairy cows with subclinical and clinical mastitis as well as to assess the concentrations of oxidant-antioxidant parameters [malondialdehyde (MDA), reduced glutathione (GSH), and total GSH levels] in both blood and milk samples. From a total of 200 dairy cows in 8 farms, 800 quarter milk samples obtained from each udder were tested in the laboratory for the presence of udder pathogens. Cultivated bacteria causing intramammary infection from milk samples were identified by Matrix-Assisted Laser Desorption/Ionization-Time of Flight (MALDI-TOF). In addition, from tested animals 60 cows were selected includıng 20 healthy cows that were CMT negative, 20 cows with subclinical mastitis (SM), and 20 cows with clinical mastitis (CM) for detection of MDA, GSH, and total GSH levels in blood and milk samples. Three hundred and eighty (47.5%; 380/800), 300 (37.5%; 300/800), and 120 (15%; 120/800) of milk samples, respectively were CMT positive or SM and CM, and those positives were cows from different farms. We observed that 87.4% (332/380), 25.3% (76/300), and 34.2% (41/120) of cows with CMT positive, CMT negative, and CM had bacterial growth. The most predominantly identified bacteria were Staphylococcus chromogenes (18.7%) obtained mainly from SM and Staphylococcus aureus (16.7%) as the most frequent cause of CM. According to our results, dairy cows with CM had the highest MDA levels, the lowest GSH, and total GSH levels in both blood and milk samples however, high MDA levels and low GSH levels in milk samples with SM were observed. Based on our results, lipid oxidant MDA and antioxidant GSH could be excellent biomarkers of cow’s milk for developing inflammation of the mammary gland. In addition, there was no link between nutrition and MDA and GSH levels.

Opis:
Neospora caninum is an important cause of abortion in dairy cattle. The general health of affected cows has not been investigated before. Therefore, the main objective of this study was to identify possible relationships between certain metabolic diseases and selected serum biochemical parameters in seropositive dairy cows against N. caninum antibodies in different stages of lactation. The study was carried out using 72 N. caninum seropositive cows and 61 seronegative dairy cows (control). Serum from all cows was tested to determine their N. caninum status (seropositive vs seronegative) using commercially available indirect enzyme-linked immunosorbent assay test kit (iELISA). In addition, serum biochemical parameters including beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and gamma-glutamyltranspeptidase (GGT) were determined using routine laboratory methods. The stage of lactation was obtained at the time of sampling from farm records. Student independent t-test showed that there was a significant difference in the serum concentrations of BHB, AST, ALT, and LDH between seropositive and seronegative cows. There was no significant association between seropositivity and the stage of lactation. However, multivariable logistic regression analysis showed that there was a strong association between seropositivity and BHB concentrations. Results of this study indicate a possible relationship between N. caninum seropositivity and certain metabolic diseases such as ketosis and fatty liver syndrome in dairy cows.

Opis:
The aim of this study was to compare the effect of parenteral and oral supplementation of Selenium (Se) and vitamin E (VTE) on selected antioxidant parameters in blood and colostrum as well as their effect on the incidence of mastitis in dairy cows during the final phase of gravidity (6 weeks) and first two weeks after calving. For the practical part of the study 36 dairy cows of Slovak pied breed in the second to fourth lactation-gestation cycle were selected. The animals weredivided into three groups: the control (C) and two experimental groups (D1 and D2). The selected groups were treated as follows: in group D1 products containing Se (Selevit inj.) and vitamin E (Erevit sol. inj.) were administered intramuscularly twice, six and three weeks prior to parturition; in group D2 a vitamin-minerals supplement in the form of sodium selenite (Na2SeO3) and dl-α-tocopherol acetate were supplemented orally for six weeks calving. The blood samples were collected from the vena jugularis in dairy cows approximately 42 days before calving (control sampling), on parturition day, and the 14th day after calving. Higher concentrations of Se and VTE were found in the blood plasma samples of both experimental groups collected on the day of parturition. In addition, the orally supplemented group (D2) showed higher Se and α-tocopherol concentrations in blood plasma on the14th day after calving as well a reduction of occurrence of mastitis by about 25 % compared to the control group. The relationship between inflammatory response and oxidative stress was also confirmed. The concentrations of milk malondialdehyde indicating lipid peroxidation during mastitis were significantly higher in milk samples from infected cows than in milk samples from healthy animals in each monitored group. In order to prevent oxidative stress and moderate inflammatory response in dairy cows it is very important to optimally balance their nutritive needs with an appropriate ratio of Se and VTE supplements. Therefore we still recommend supplementation of the cows’ postpartum dietwith 0.5 mg of Se/kg dry matter (DM) and 102 mg of dl-α-tocopherol acetate/kg DM to stabilize their optimal blood levels, stimulate the activity of glutathione peroxidase and reduce the incidence of mastitis.

Opis:
The aim of the study was to use evolutionary operations (EVOP) to evaluate changes in the behaviour of dairy cows depending on the strategy according to which they were grouped after calving. The experiment was carried out on a Danish farm keeping about 200 Holstein cows. The farm had two separate areas for lactating cows: a small area with 54 waterbeds and a larger area with 133 beds with mattresses. During the experiment both areas were filled with cows. Cows after calving were introduced to either the small area (group) or the large area (group). After 14 days, the cows from the small group were transferred to the large group. The impact of different cow grouping strategies on their lying time, considered a welfare indicator, was examined. During the 210-day experiment, 195,703 observations were collected. The behavioural data were analysed using a linear mixed-effect regression model fitted by the maximum likelihood method. Days in milk, parity number, and lying time of herd mates were found to significantly affect the lying time of individual cows, while the strategy of cow grouping after calving had no effect on lying time.

Response to the superovulatory hormone treatments varied for the type of breed and doses of superovulatory hormone used. Ovarian response of 42 crossbred HF (50%, 75%) and pure dairy cows were evaluated based on ultrasonographic count of CL and embryo recovery for quality assessment. Ovarian response rate was significantly higher (P<0.05) in the crossbreds than in the pure bred cows. The maximum response achieved (CL count, mean ± SE) was 14.6±1.1 and the least with 11.2±1.1, 75% HF at 650IU and pure HF at 800IU, respectively. Significantly higher (p<0.05) number of UFO were collected at a dose of 500 IU while transferable embryos were higher at 650IU in both the 50% HF and 75% HF cows. Pure bred cows responded fairly with more CL and produced higher number of transferable embryos at a dose of 800 IU FSH. In conclusion, the optimal dose for maximum response (CL count) exhibited in cross breed HF cows is 650 IU.

Opis:
The paper analyses technical equipment of the selected dairy farms. Data from questionnaires carried out in 96 farms in 2015 constituted a research material. Municipalities Lszewo-Borki in Mazowieckie Voivodeship were covered by the survey. A survey questionnaire, which consisted of two parts, was a research instrument. The first concerned general information on a farm and its owner, and the other consisted of eight questions on technical equipment used for breeding dairy cows. The research allowed to determine that farmers assessed the condition of their machinery park as average (50%) or good (40%). One out of ten farmers claimed that the used machinery park in a farm is in a bad condition. Majority of respondents have allotted from PLN 20 to 50 thousand for investments related to enhancement of a machinery park within the last 5 years. On the other hand, a considerable part of farms allotted up to PLN 20 thousand for development of a machinery park. The investigated group included also farms, which allotted more than PLN 500 thousand for development of a park.
W pracy dokonano analizy wyposażenia technicznego wybranych gospodarstw specjalizujących się w chowie bydła mlecznego. Materiał badawczy stanowiły dane pochodzące z badań ankietowych przeprowadzonych w 96 gospodarstwach w 2015 roku. Obszarem badań objęto gospodarstwa położone na terenie gminy Olszewo - Borki w województwie mazowieckim. Instrumentem badawczym był kwestionariusz wywiadu, który składał się z dwóch części. Pierwsza dotyczyła ogólnych informacji o gospodarstwie i jego właścicielu, natomiast druga składała się z ośmiu pytań dotyczących wyposażenia technicznego wykorzystywanego w chowie bydła mlecznego. W wyniku badań ustalono, że rolnicy ocenili stan swojego parku maszynowego jako średni (50%) lub dobry (40%). Co dziesiąty badany rolnik, uważał, że wykorzystywany park maszynowy w gospodarstwie jest w złym stanie. Większość badanych w ciągu ostatnich 5 lat na inwestycje związane z rozwojem parku maszynowego przeznaczyła od 20 do 50 tys. zł. Natomiast znaczna część gospodarstw na rozwój parku maszynowego przeznaczyła do 20 tys. zł. W badanej grupie były również gospodarstwa, które przeznaczyły na rozwój parku ponad 500 tys. zł.

Opis:
The impact of age at the fi rst calving on lifetime milk yield, life span and herd life in dairy cows. The increasing importance of functional traits (e.g. longevity) in cattle breeding is the result of their direct effect on profi tability of production. The main objective of the study was to determine the infl uence of age of the fi rst calving on lifetime milk yield, life span and herd life in Polish dairy cows. Cows were kept on farms with milk performance recording system. One-way analysis of variance was used to calculate the impact of age of the fi rst calving on selected traits. Cows that fi rst calving occurred at the age of 791–850 day achieved the highest lifetime milk, fat and protein yield per one day of life (P ≤ 0.01). Moreover, their life span was also the longest (P ≤ 0.01) and milk and protein yield per 1 day of utilization were the highest (P ≤ 0.01). Obtained results suggest that the most favorable time of calving for dairy heifers is between 791–850 day of life. Therefore, milk producers should carefully consider the most suitable time of heifers insemination in order to achieve the most satisfying milk production.

Opis:
Wykonano analizę poprawności żywienia krów mlecznych pod względem energetycznym i białkowym. Materiał badawczy stanowiły wyniki użytkowości stada 250 krów za 6 miesięcy, od listopada 2010 r. do kwietnia 2011 r. Stado podzielono na 3 grupy technologiczno-żywieniowe na podstawie wydajności mlecznej krów. Zmian składu grup dokonywano raz w miesiącu. Grupa A, o najwyższej wydajności mleka, otrzymywała dawkę obliczoną na 38 kg mleka. Dawkę pokarmową dla grupy B zaplanowano na 28 kg, a dla grupy C - przed zasuszeniem na 19 kg mleka. Przeciętne wydajności grup w kolejnych miesiącach badań były dość stabilne. Różnice w wydajności mlecznej w obrębie grup były bardzo duże i przekraczały 20 kg. W grupie A u 34% krów zaobserwowano niedobór energii pobranej w paszy w stosunku do aktualnych potrzeb, natomiast w grupach B i C - nadmiar energii w pobranej paszy, odpowiednio u 62% i 75% krów. Niedobór białka w pobranej paszy wystąpił u 11% krów w grupie A, u 10% krów w grupie B i 24% w grupie C, a nadmiar odpowiednio - u 28, 19 i 22%.
Correctness of feeding dairy cows was analysed in terms of sufficient energy and protein quantities supplied in the diet. As the source data for research, production results over 6 months (since November 2010 till April 2011) for the herd of 250 dairy cows were used. The herd was divided into 3 technological-nutrition groups of cows on the basis of milk yields. Once a month the structure of groups was corrected. The group A, of highest milk yielding cows, was fed with a diet provided for 38 kg milk production. Diet B was provided for group of cows yielding 28 kg milk, whereas for group C - the cows just before drying off - diet for 19 kg milk production. Average milk yields of particular groups in succeeding months of experiment were quite stable. However, the differences in milk yielding within particular groups were considerable and exceeded 20 kg. Shortage of energy in diets, in relation to the actual demands, was observed in 34% cows of group A; instead, in groups B and C the surplus of energy in diets fed - was noted in 62% and 75% cows. Protein deficiency in uptaken feed occurred in 11% cows of group A, in 10% cows of group B and in 24% cows of group C, while the excess in 28, 19 and 22% cows, respectively.

Opis:
Celem pracy było wyodrębnienie nowych wskaźników oceny budynków inwentarskich dla bydła mlecznego ze szczególnym uwzględnieniem ich technicznego wyposażenia. Zakresem pracy objęto obory z uwięziowym i wolnostanowiskowym systemem utrzymania, zróżnicowane pod względem pogłowia zwierząt w stadach. W opracowanym formularzu badawczym zestawiono zbiór podstawowych informacji na temat warunków produkcji bydła w poszczególnych obiektach. W trakcie bezpośrednich wizyt badawczych w gospodarstwach okazało się, że w oborach zaobserwowano nowe elementy, które wykorzystano do zaproponowania porównawczych wskaźników oceny obiektów inwentarskich dla bydła mlecznego. We wszystkich badanych obiektach z uwięziowym systemem utrzymania stwierdzono występowanie rozwiązań niestandardowych w budynku inwentarskim, co potwierdza inwencję producentów mleka we wprowadzaniu zmian w technicznym wyposażeniu budynków inwentarskich.
The paper aimed at distinguishing new indices for evaluation of barns for dairy cows including their technical equipment. The detailed investigations covered barns with tied and free-stall maintenance systems including farms with different size of dairy herds. The elaborated research questionnaire to carry out the investigations included the set of basic data concerning conditions of dairy production in the barns. During direct research visits in the investigated farms some new elements were observed in the barns and as a result new comparative indices were proposed to evaluate livestock buildings for dairy cows. The all investigated barns with tied maintenance system were characterized by the use of non-standard solutions in the area for cows. Such results of the investigations confirm imagination of dairy farm owners to implement changes in the technical equipment of the managed barns.

Opis:
Lameness has a detrimental effect on herd productivity, and is second only to mastitis in this respect. The objective of this study is to calculate the cost of different types of lamenes. This would enable effective decision making of whether it may or may not be economically optimal for a cow to be kept in the herd, inseminated, culled or replaced. The animals included in the survey were reared in different variants of free-range production systems. For the purposes of the study, cows from three farms were divided into two groups—cows with diagnosed lameness, and healthy cows over the 305-day lactation period. According to the results of the survey, the revenues from dairy cows with lameness were reduced by up to 15%, whereas the expenses per animal were higher by up to 17%. Treatment costs of affected cows were increased from 1.5 times at the second farm to 17.3 times at the third farm. The absolute economic results (profit per cow) in lame cows were reduced by 23.8% at the second farm and by 28.9% at the first farm. Cost effectiveness in healthy cows was by 11.6% higher for the second and by 32.6% higher for the first farm. The production costs of 1 litre milk in lame cows were increased by 17.1% (third farm) and by 29.3% (second farm).
Występowanie kulawizn u krów ma negatywny wpływ na produktywność stada i jest drugim po zapaleniu wymienia czynnikiem w tym zakresie. Artykuł prezentuje szacowany koszt różnego rodzaju kulawizn, co pozwoli podjąć optymalną z ekonomicznego punktu widzenia decyzję, czy zainfekowana krowa powinna pozostać w stadzie, czy też powinna zostać wymieniona lub poddana inseminacji. Zwierzęta objęte badaniem były hodowane w różnych wariantach systemów produkcji na wolnym wybiegu. Dla celów badawczych krowy w trzech gospodarstwach zostały podzielone odpowiednio na dwie grupy ‒ krowy zezdiagnozowaną kulawizną oraz krowy zdrowe. Krowy z obydwu grup były w okresie trzystapięciodniowej laktacji. Po przeprowadzeniu badania stwierdzono, że zysk z krów mlecznych ze zdiagnozowaną kulawizną został zmniejszony o 15%, podczas gdy wydatki na zwierzę były wyższe o 17%. Koszty leczenia wzrosły od 1,5 razy w drugim gospodarstwie do aż 17,3 razy w trzecim. Całkowite zyski ekonomiczne (zysk na jedną krowę) u krów ze zdiagnozowana kulawizną zostały zredukowane o 23,8% w drugim badanym gospodarstwie oraz o 28,9% w pierwszym. Ekonomiczna opłacalność zdrowych krów była wyższa o 11,6% w drugim gospodarstwie oraz o 32,6 % w pierwszym. Koszty produkcji jednego litra mleka u krów z kulawizną wzrosły o 17,1 % (trzecie gospodarstwo) i 29,3% (drugie gospodarstwo).

Opis:
The aim of this study was to evaluate the influence of environmental housing conditions on the milk yield of dairy cows. Measurements were taken in the summer period from June to September, 2020 and in the winter period during January, 2021 on a large-capacity farm of Holstein Friesian cattle. Cows were housed in free stall barn with the lying boxes and selected during the second or third lactations, in the summer period from the 51st day to the 135th day and in the winter period from the 64th day to the 120th day of lactation. The average temperature in the housing was 23°C in summer, and 7.05°C in winter. The average THI (thermal humidity index) value in summer was 70.43, but during the day the THI values sometimes reached 75. The dairy cows were therefore exposed to heat stress during summer. Increasing THI and temperature values negatively affected the milk yield, as there was a negative correlation between both THI and milk yield (r = −0.641; p < 0.01) and temperature and milk yield (r = −0.637; p < 0.01). Milk production in winter was at 58.77 kg per day and in summer at 49.55 kg per day. In the summer, the milk had a significantly lower content of fat (p < 0.05), proteins (p < 0.001), lactose (p < 0.001), minerals (p < 0.001) and conversely, a higher number of somatic cells (p < 0.01). These results show that worse environmental conditions during the summer negatively affected the level of milk yield and the composition of the cows’ milk.
