Literature reveals that different feeding regimes affect performance of broiler chickens. A study was conducted to investigate the effects of different phase feeding programs on performance of Cobb broiler chickens (n = 90) using commercial broiler diet fed ad libitum under similar conditions for 36 days under a positivist research design. Treatment 1 (T1), was the control group under two phase compared to three (T2) and four phase (T3) feeding programs. Treatments were replicated three times. Growth rates, carcass weight and feed conversion ratio were measured. Results of the study showed that broiler chickens under T1 were significantly lighter (p<0.05) at 1789g than T3 (1871g) at day 36. Carcass weights and weights of internal organs were significantly different amongst the feeding phases, with superior weights noted on T3 feeding program. Broilers on T3 had significantly (p<0.01) heavier feet weights than those on T1 and T2. T2 had the least feed conversion ratio of 1.34 compared to T2 (1.32) and T3 (1.28). We recommended that small scale broiler farmers should adopt four phase feeding program to achieve superior growth rates, carcass weight and higher feed conversion ratios.

Samples of browse legume diets Acacia angustissima (AA), Leucaena trichandra (LT) and Calliandra calothyrsus (CC) were evaluated for degradability using the nylon bag technique with three rumen-cannulated steers in order to determine dry matter (DM) and crude protein (CP) disappearance. The browse legumes were included in the diets at 30% and they were made isonitrogenous such that each diet contained 16% CP. A completely randomized design (CRD) was used in this trial. The nylon bags were sequentially added for 0, 12, 24, 48, 72 and 96 hours. The results showed that the A. angustissima diet had a significantly higher (P<0.05) effective degradability value (81.85%) for DM than the L. trichandra diet (73.15%) and C. calothyrsus (62.27%) diets at a k-value of 0.02. The effective degradability of CP of 56.5% for A. angustissima diet was significantly different (P<0.05) from L. trichandra (38.0 %) and C. calothyrsus (24.9%). Potential degradability of DM ranged from 61% (CC) to 82.4% (AA) while that for CP ranged from 25.2% (CC) to 57.12% (AA). The findings of this study showed that diets prepared using A. angustissima were more degradable than those from L. trichandra and C. calothyrsus possibly due to differences in tannin content. It is concluded that highly degradable diets can be formulated for small ruminants using browse legumes.

The study was conducted to determine the effects of partially substituting maize with red sorghum brewer’s grain on the performance of broiler chickens at finishing stage. The finishing diets contained 0%, 5%, 10% and 15% brewer’s grain in place of maize. During week four, five and six 48 unsexed hybrid broilers were randomly allocated to 12 pens, four in each pen and allocated to the four diets.
The feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were measured weekly. There was significant difference (P<0.01) in feed intake between birds fed on 0% (0.50kg) and those on 15% inclusion levels (0.54g). FCR showed significant difference (P<0.05) between birds fed on 0% (3.13) and those fed on higher levels (>4). ADG showed significant (P<0.01) difference in birds fed on 0% (42.4g) and those on higher inclusion levels (about 30g).
It is concluded that brewer’s grain can partially replace maize up to 5% at finishing stage without affecting broiler growth.
