  This study was conducted with sixty hybrid (Chinchilla and New Zealand white) weaner rabbit of 5 weeks old to determine their response to graded levels of raw Bambara groundnut (Vigna subterranean (L.) Verdc) Offal (BGO) diets. The groups were randomly assigned to five diets in a Completely Randomized Design (CRD) experiment. Treatment groups were designated as treatments 1-5. There were twelve rabbits per treatment and each treatment was replicated three times with four rabbits per replicate. The inclusion level of Bambara Groundnut Offal (BGO) in the diet was 0, 5, 10, 15 and 20%, respectively. And the experiment lasted for eight weeks, parameters measured were final live weight, weight gain, feed and protein intake, feed conversion ratio, Protein Efficiency Ratio (PER), feed cost and carcass quality. The result of the experiment showed that there were significant (p<0.05) differences in daily feed intake, protein intake, protein efficiency ratio, dressed percentage and intestinal weight. Rabbits fed 15% BGO diet had numerically higher daily weight gain (25.10 g), final live weight (2.18 kg), better Feed Conversion Ratio (FCR) of 3.26, Protein Efficiency Ratio (PER) of 3.43 and lowest cost per kg live weight gain (N100) than rabbits fed other graded levels. Increase in the inclusion level of BGO in the diets resulted in a significantly (p<0.05) increase in the total feed cost. It was concluded that weaner rabbits could be fed 15% BGO diets to enhance daily weight gain and final live weight.

  The experiment was carried out using two hundred 4 weeks old broiler finisher birds to evaluate their response to diet with different levels of Brewers Dried Grain (BGD). The diet was made to replace maize with brewer’s dried grain at 0%, 25%, 50%, 75% and 100% to form treatment diets, 1, 2, 3, 4 and 5 respectively. The formulated rations were made in such a way that other ingredients apart from maize and brewer’s dried grain remained the same. The two hundred 4 weeks old broiler birds of Anak ® strains were allotted in a completely randomized Design into five treatment groups. Each treatment had 40 birds, which was replicated two times with 20 birds each. The experiment lasted for eight weeks with feed and water provided ad-libitum. Results showed significant differences in the birds growth performance, birds in T3 had the most superior (p<0.05) final live weight, daily weight gains and feed conversion ratio, followed by T2, T4 and T5. The least value was obtained from birds in T1. The daily feed intake showed a reverse trend, as birds consumption significantly (p<0.05) improves as the level of maize increased in the diet, with the highest (p<0.05) intake recorded for birds in T1 (100% maize, the least value from birds in T5 (100% brewer’s dried grains), the least cost per kg of feed was obtained from diet (T5), it decreased as the brewer’s dried grain increased in the diet. Cost per kg weight gain showed a similar trend and tended to favour birds fed higher levels of brewer’s dried grain. The use of brewer’s dried grain in broiler finisher diet should be encouraged as it gave promising results in terms of growth performance, better feed conversion and body weight gains.

  Four isonitrogenous diets A-control B-12% palm oil, C-12% groundnut oil and D-33% corn meal were fed to 40 weanling rabbits. The experiment was a Completely Randomized Design (CRD). At the end of the 15th week, blood was collected from 24 of the rabbits through cervical cutting while 16 were treated with niacin for another 8 weeks. The blood was collected to ascertain whether the high dietary energy diets was stressogenic on the rabbits through their blood parameters. The result showed significant (p<0.05) reduction in all the blood parameters except the white blood cells. This tended to indicate that the high dietary treatments (B and D) did impose stress on the rabbits, hence, these blood constituents were altered compared to the control and groundnut oil (A and C) diets. The observed significant (p<0.05) reduction in haemoglobin, packed cell volume and neutrophil production indicate that the oxygen supply to tissues and organs of the rabbits were different and not normal. The significant (p<0.05) pattern was quite the same when the effect of niacin treatment was considered in another analysis. The drug reduced the fat deposits in the coronary arteries and this was reflected in the photomicrograph of the arteries.
