The present study investigated the effects of dietary calcium (Ca), phosphorus (P), and vitamin D (VD) supplements on growth performance, Ca:P digestion and metabolism, and serum biochemical indexes of growing male mink (Mustela vison) under conditions of a fixed 2:1 ratio of Ca to P. About 135 dark male mink were randomly assigned to nine groups. The experiment was conducted with a 3 × 3 (Ca:P × VD) factorial design using a corn–fish meal-based diet that contained 2.3% Ca, 1.15% P, and 2100 IU kg−1 VD. The supplementary Ca and P levels were 0%:0%, 0.4%:0.2%, and 0.8%:0.4% of the diets, respectively, whereas supplementary VD levels were 0, 2000, and 4000 IU kg−1. The Ca and P dosage had a significant effect on growth performance of the mink (P < 0.05). The appropriate VD level, which was 4100 IU kg−1, significantly improved protein utilization and Ca and P digestibility of growing mink (P < 0.05). In addition, excreta pollution to the environment was also significantly reduced (P < 0.05). In conclusion, Ca:P (3.1%:1.55%) and VD (4100 IU kg−1) had an important effect on growth performance and protein utilization in growing mink and could reduce environmental pollution by improving protein and P utilization.

The effects of dietary replacements of fish meal with soybean meal on growth performance, heamatology and serum biochemistry in juvenile Labeo cubie were evaluated. Four hundred and fifty (450) apparently healthy juvenile Laboe cubie were distributed into one of fifteen 1000 L tanks divided into five groups and fed any of diets A (0% soybean meal); B (30% soybean meal); C (40% soybean meal); D (45% soybean meal) and diet E (75% soybean meal) for 56 days. At set time points day 7, 14, 28 and day 56, five fish were randomly selected per tank for growth assessments, heamatology and serum biochemical evaluations. Growth performance indices decreased significantly (p < 0.05) along the gradient of soybean meal inclusion and the duration of feeding. The erythrocytes count increased significantly (p < 0.05) at day 14 in fish fed soybean meal diets and decreased significantly (p < 0.05) beginning at day 28 in fish fed soybean meal-based diets. The haematocrit of fish fed diets D and E were significantly (p < 0.05) lower at day 28 compared to day 56. There were no significant variations in haemoglobin concentration and the leucocytes counts (p > 0.05). The proteins, blood glucose and the transaminases increased significantly (p < 0.05) along gradient of dietary inclusion and duration of feeding in the first 28 days while creatinine kinase activity, blood urea nitrogen and uric acid concentration remained significantly elevated (p < 0.05) in fish fed the soybean meal-based diets. The results of the study show juvenile L. cubie may tolerate up to 40% dietary inclusion of soybean meal as replacement for fish meal.

Experiments were conducted with Ross-type broiler chickens to determine the optimum level of inclusion of fish meal and the replacement value of blood meal for fish meal in broiler finisher rations. The optimum level of inclusion of fish meal was found to be 5%. Fish meal levels beyond 10 per cent tended to produce unacceptable fishy taste and odour in the meat. This level was successfully replaced by 4% blood meal without adverse effect on growth performance and taste or odour of the meat. The use of blood meal resulted in lower feed costs and feed cost per kg weight gain.

Aim. To investigate the vitamin D status in highly productive cows during winter housing period and effect of cholecalciferol by various ways of vitamin D 3 injection to cows in last days of gestation and after calving. Methods. Enzyme-linked immunoassay, spectrophotometry. Results. It has been stated that intramuscular injection of cholecalciferol into cows caused increase of the vitamin D 3 active metabolite – 25-OHD 3 , calcium, phosphorus and magnesium levels together with decrease of alkaline phosphatase level in pre- and post-natal periods. Oral supplementation makes little infl uence on the studied blood parameters of cows. Conclusions. Extrabuccal administration and oral supplementation of cholecalciferol in winter housing period to high-yield cows in the last days of gestation and after calving is accompanied by increased levels of its metabolites and their effect on mineral metabolism in the postnatal period. The nature of these changes depends on the mode of vitamin D administration and the physiological state of the cows.
