Opis:: By providing the body with essential nutrients, colostrum plays an immune and immunostimulating function. Colostrum quality depends on multiple factors, including microbial presence. This study aimed to explore the effect of non-aureus staphylococci on colostrum quality. Physical and chemical properties, fatty acid profile of cow colostrum were determined. In our study, we identified three non-aureus staphylococci species in the colostrum: S. sciuri, S. xylosus and S. warneri. The percentage of dry matter in staphylococci positive and negative colostrum samples did not differ significantly. Contents of fat, protein, and lactose in the colostrum were similar. The content of butyric (С4:0) and capric (С10:0) acids was significantly higher in the colostrum fat from samples positive for non- aureus staphylococci. Total bacterial count was lower in non- aureus staphylococci positive samples, while pH increased. The percentage of β-casein was lower in colostrum with a positive culture for non- aureus staphylococci.

Opis:: The aim of the in vitro study was to determine the effect of corn dried distillers grains with solubles (corn DDGS), used as a replacement for the concentrate ingredients of sheep diet, on rumen fermentation. The material for the study was the ruminal fluid of Polish Merino sheep which was incubated during 4-, 8- or 24-hour periods. Five groups of samples were prepared for in vitro fermentation: C – control, incubated with the substrate consisting of the concentrate ingredients; D1, D2 and D3, where DDGS was used as a substrate added in proportions of 10, 20 and 30% of dry matter of the concentrate; and D4, where 100% DDGS was used as a substrate. After fermentation, the gas and short chain fatty acids (SCFAs) analyses were performed using gas chromatography. The ammonia concentration and pH were also determined, and the SCFA utilization index (NGR), the fermentation efficiency (FE) and the index of cell yield of ruminal microorganisms (CY) were calculated. This research showed no effect of DDGS on the methane emission. The positive correlations between the amount of methane and ammonia concentrations in the 8- and 24-hour fermentation periods were found. DDGS addition increased propionate proportion, but decreased production of acetate (p<0.01). Additionally, D1, D2, D3 and D4 substrates lowered isobutyrate (p<0.05) and isovalerate (p<0.01) production. Based on the results obtained, it can be stated that partial substitution of the concentrate ingredients with DDGS did not have deleterious effect on sheep rumen fermentation processes.

Opis:: The objective of the study was to evaluate the effect of energy contents in a dry period diets in “7+1” feeding strategy of dry cow including 7 weeks of the dry period (far-off) and 1 week of a close-up period, on colostrum quality and the immune status of calves. Forty Holstein multiparous cows were dried at 56d before the expected date of calving and were assigned to the higher energy diet group (HE; 0.69 UFL/kg DM, NDF 52% DM), or the lower energy diet group (LE; 0.61 UFL/1kg DM, NDF 56% DM). From -7d to the expected calving date up to 21 d of lactation, all cows were fed the same fresh, lactation diet. Samples of colostrum were collected within 2h after parturition and its density, dry matter content and concentrations of immunoglobulins, fat, protein, lactose, urea and somatic cell counts were measured. Calves were weighed 2 h after calving and on the 21d of life. On 3d and 21d of calves’ life blood samples were collected and the concentration of IgG, IgA, IgM, insulin-like growth factor 1 (IGF-1) as well as total protein and albumin concentrations were determined. Treatments had no significant effect on composition of colostrum and serum immunoglobulins and IGF-1 concentration. In both groups the weight of calves at birth was similar, still daily body weight gain during 21 day of rearing period in HE group was higher than in the LE group (P=0.05).

Opis:: An effect of mammary gland infection caused by Streptococcus uberis on the changes in cows’ milk composition and its physicochemical properties was examined. The study was conducted in the herd of Slovak Pied breed cattle (with a share of HF blood), in 2nd and 3rd lactation, after 4th month of milking. Milk samples were collected from a quarter milking. The samples were subjected to microbiological analysis, basic milk composition, total bacteria count, somatic cell count and physicochemical properties were examined. Also analyses of protein fractions share and fatty acids profile were conducted. An effect of bacterial infection of the mammary gland bring an increase (P<0.01) in somatic cell count was observed in this study. Milk samples contaminated with S. uberis were characterized by higher (P<0.05) total bacteria count and total protein compared to milk samples collected from non-infected mammary gland. The level of κ-casein was significantly (P<0.05) decreased in cows with subclinical mastitis caused by S. uberis. Significant (P<0.05) reduction in the share of C13:0 acid, and an increased level of C18:0, C18:1n7t and CLA were observed in milk contaminated with S. uberis compared to healthy cows’ milk. It should be concluded that S. uberis causes the increase in total bacteria count, SCC and the decrease in κ-casein level, which significantly affects deterioration of technological quality of cows’ milk.

Opis:: The aim of this study was an evaluation of the effects of two species of coagulase negative staphylococci (CNS), Staphylococcus xylosus and Staphylococcus warneri, on the changes in technological parameters of cows’ milk. The study was conducted in a herd of Slovak Pied cattle breed (with share of HF blood). Based on the performance results from three subsequent months, cows in the 2nd and 3rd lactation with SCC up to 200 thousand/ml (8 heads, 32 quarters), and above 800 thousand/ml (8 heads, 32 quarters), after the 4th month of lactation, were selected. The samples were subjected to microbiological analysis, total bacteria count, somatic cell count; basic milk composition and physicochemical properties were also examined. The research has found the impact of bacterial infection on the increasing (p<0.05) of the number of somatic cells and a decrease (p<0.01) in protein levels in milk due to both types of staphylococci. There was a significant (p<0.05) reduction in C8: 0, C10: 0 and the total amount of saturated fatty acids in the milk of the infected cows in comparison to the healthy ones. The research also revealed higher (p<0.01) levels of C14: 0 and C20: 1 in milk from the healthy cows.

Opis:: WSTĘP: Celem pracy była ocena wzrastania dzieci dializowanych w latach 2000–2016. MATERIAŁ I METODA: U 102 dzieci w wieku 10,2 roku ± 5,66 przeanalizowano rozpoznania, schorzenia dodatkowe, czas i rodzaj dializoterapii, losy pacjenta, zastosowanie hormonu wzrostu. Niedobór wzrastania (Z score) stwierdzono u 87 dzieci przy rozpoczęciu badania i u 94 przy zakończeniu leczenia. WYNIKI: U 60% dzieci pierwszą metodą dializoterapii była dializa otrzewnowa, u 38% hemodializoterapia, u 2% wyprzedzające przeszczepienie nerki. W chwili zakończenia obserwacji 70% pacjentów żyło z czynnym przeszczepem nerki, 15% było nadal dializowanych, 13% zmarło, u 2% doszło do poprawy funkcji nerek. Średni czas dializoterapii (94 dzieci) wynosił 34,6 mies. (1–136 mies.) i był dłuższy w latach 2000–2008 niż w okresie 2009–2016 (śr. 43,3 ± 32,7 mies. vs 18,3 ± 13,1; p = 0,00005). W grupie ze schorzeniami dodatkowymi (46% dzieci) stwierdzono większy niedobór wzrostu na początku (Z score 0: -2,3 ± 2,3 vs -1,08 ± 1,6; p = 0,003) i na końcu leczenia (Z score 1:-2,7 ± 2,6 vs -1,2 ± 1,5; p = 0,001) oraz dłuższy czas dializoterapii (42,7 ± 34,4 mies. vs 27,8 ± 23,8; p = 0,02). Z score 0 wyniósł dla wszystkich pacjentów -1,7 ± 2,0 (-9,3 do +2,0) przy rozpoczęciu leczenia i nie różnił się od Z score 1: -1,9 ± 2,2 (-8,3 do +2,4); p = 0,37 w chwili zakończenia. U 42,5% dzieci na początku i u 45% na końcu terapii Z score był < -2,0. W grupie 17% dzieci leczonych hormonem wzrostu stwierdzono wyrównanie się niedoboru wzrostu po zakończeniu dializoterapii w porównaniu z grupą nieleczoną (Z score 1: -2,4 ± 1,7 vs -1,9 ± 2,3; p = 0,37). WNIOSKI: Niskorosłość stanowi istotny problem dzieci dializowanych. Współchorobowość jest czynnikiem pogarszającym niedobór wzrostu. Zastosowanie hormonu wzrostu daje szansę na poprawę wzrastania.
INTRODUCTION: The aim of the study was to assess the growth in children on RRT during the period 2000–2016. MATERIAL AND METHODS: The diagnosis, comorbidity, RRT data, patient outcome and growth hormone (GH) usage (in 102 patients) and height Z score for 87 patients at the start of RRT and for 94 patients at the end of RRT were analyzed. RESULTS: In 60% of patients, peritoneal dialysis was the first method, in 38% hemodialysis and in 2% a preemptive transplantation was performed. The average dialysis time was 34.6 months (1–136 months) and it was statistically longer in the years 2000–2008 than in 2009–2016 (av. 43.3 ± 32.7 months vs 18.3 ± 13.1; p = 0.00005). In the group with comorbidity (46% patients) Z score 0 (start) and Z score 1 (the end) were lower than in the group without comorbidity (average Z score 0: -2.3 ± 2.3 vs -1.08 ± 1.6; p = 0.003) and the dialysis time was also longer (p = 0.02). The Z score in all the patients at the start of RRT was -1.7 ± 2.0 (min: -9.3 to max: +2.0) and there was no statistical difference in comparison to the Z score at the end of RRT: Z score 1; p = 0.37. A Z score < -2.0 was found in 42.5% of children at the start and in 45% at the end of RRT. In 17% of the GH treated group, growth improvement was shown by no difference in Z score 1 in comparison to the group without GH therapy. CONCLUSION: Short stature is still a problem in children on dialysis. Comorbidity is important factor of growth retardation. GH therapy is effective in children on RRT.
