    Opis:
    A ten-week experiment using twenty four (24) weaner rabbits (Chinchila x New Zealand White) aged 8 to 9 weeks with an average initial body weight of 431.20+0.74g were randomly allocated to four treatment diets of T1(control), T2(5% NLM), T3(10% NLM) and T4(15% NLM) in a completely randomized design. They were fed for 10 weeks during which data on growth and haematology were collected and analysed using analysis of variance (ANOVA) and means separated using Duncan Multiple Range Test. The results showed that the average total body weight gains were 739.60g (T1), 717.85g (T2), 740.18g (T3) and 729.45g (T4).There was no significant difference (p>0.05) when T1 and T3 as well as T2 and T4 were compared but significant (p<0.05) when T1 and T2 as well as T3 and T4 were compared. Also the average weekly feed intake showed that T1, T2, T3 and T4 consumed 313.91g, 313.24g, 312.48g and 314.69g respectively. However, there was significant difference (p<0.05) when all the treatments were compared in this respect. The feed conversion ratio (FCR) showed that T3 (4.22) was the best followed by T1 (4.24), T4 (4.31) and T2(4.36) with significant differences (p<0.05) among them except (p>0.05) between T1 and T3. The haematological indices showed that though all the parameters fell within the normal physiologic ranges, the PCV was 37.62% (T1), 38.42% (T2), 39.60% (T3) and 39.03% (T4) and when compared, were all significantly different (p<0.05) except (P>0.05) for T3 and T4 while the haemoglobin concentration showed that T1(13.47g/dl) was significantly different (p<0.05) from T2(14.18g/dl), T3(14.34g/dl), and T4(13.97g/dl). The white blood cell count showed that T3 (10.62 x109/L) had the highest value followed by T1 (10.12 x109/L), T4 (9.34 x109/L) and T2 (9.18 x109/L) with a significant difference (p<0.05) occurring when T1 and T3 were compared to T2 and T4 while the red blood cell counts indicated that T1 had the highest value of 4.92 x106/L followed by T3(4.89 x106/L), T2(4.73 x106/L) and T4(4.65 x106/L) without any significant difference among the treatments. All the values fell within the normal range. It is therefore recommended that inclusion of neem leaf meal in the diets of rabbits up to 10% is not detrimental since it improved feed conversion ratio (FCR), growth performance and had no negative effect on haematological values.

    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:
    A total of 60 Russ 2011 two weeks old broiler chicks with an average weight of 215.33+4.55g were fed with diets compounded with sweet potato leaves (SPL) for 56 days. The diets consist of T1 (0% SPL), T2 (5% SPL), T3 (10% SPL) and T4 (15% SPL). The proximate composition of the SPL was determined in the laboratory. The birds were randomly allocated to four treatments using completely randomized design (CRD). Each treatment was subdivided into three replicates of five chicks each. At the end of the experiment, all data collected were subjected to one way analysis of variance and difference in means was separated using Duncan’s New Multiple Range Test. The results showed no significant difference (p>0.05) in the average body weight gain, feed intake, feed conversion ratio (FCR) and protein efficiency ratio (PER). However, birds on T2 (32.77g) had the best daily body weight gain followed by T4 (30.36g), T3 (30.06g) and T1 (29.21g) while in terms of daily feed intake, T4 (98.20g) consumed most followed by T2 (98.17g) and T3 (96.59g) whereas, T1 (92.38g) consumed the least feed. The birds on T2 (3.00) demonstrated the best FCR followed by T1 (3.16), T3 (3.21) and T4 (3.23). Also T1 (1.59) showed the best PER closely followed by T1 (1.53), T3 (1.46) and T4 (1.43). There was, however, a significant difference (p<0.05) in Hb concentration when T2 (11.62g/dl) and T3 (12.48g/dl) were compared with T1 (10.34g/dl) and T4 (10.21g/dl). In the PCV, a statistical difference (p<0.05) also was observed between T1 (24.73%) and others (T2 (28.18%), T3 (28.97%)and T4 (27.14%)) while similar trend (p<0.05) was seen in the RBC count when T4 (9.72x106/ul) was compared with T1 (10.21 x106/ul), T2 (10.81x106/ul) and T3 (11.43x106/ul) and no significant difference (p>0.05) among all the treatments with respect to WBC (T1 (21.23x103/ul), T2 (19.18x103/ul), T3 (21.26x103/ul) and T4 (22.63x103/ul)). Although the haematological parameters fell within normal physiological ranges, there was a gradual increase in these values as the inclusion levels progressed till T3 (10% inclusion) and then a decrease. It is therefore recommended that inclusion of SPL up to 5% in the diet of broilers is good for enhanced body weight gain, FCR and PER and up to 10% for enhanced haematological parameters.
