Dietary treatments consisted of basal diet supplemented with 0 (control), 0.05 and 0.10% L-arginine, respectively. A completely randomized design was used with turkeys randomly allotted to 18 pens; each pen housed eight birds. Six pens were assigned to each treatment. Growth performance of the birds, cook loss, refrigeration loss, freeze loss and water absorptive power of the breast meat were measured. Finisher turkeys fed diet supplemented with 0.05 % L-arginine and control group had reduced (P < 0.05) feed intake and improved (P < 0.05) feed conversion ratio. Meat samples from turkeys fed diet supplemented with L-arginine showed increased (P<0.05) cook loss weight (in g) and percentage cook loss when compared with control group. Turkeys fed diet supplemented with 0.10% arginine had the highest (P<0.01) percentage refrigeration loss, freeze loss weight (g) and percentage freeze loss. Increasing supplementation level of arginine showed a linear reduction (P<0.001) in the thaw weight of breast meat. Sensory parameters of meat sample were not influenced (P>0.05) by varying level of arginine supplemented. In conclusion, arginine supplementation seems to weaken the muscular cross-bridges in breast meat and hence resulted in higher cook loss, refrigerated loss and freeze loss.

Eighteen intact male growing pigs (Landrace), weighing 44.6kg, were housed in a concrete cubicle with six pigs per treatment for six weeks. Pigs were fed ad libitum feed and water. Experimental diets were: control, microbial treated cassava peel and leaf blend and untreated cassava peel and leaf blend diets. The Cassava peel-leaf blend replaced maize at 100%. Cassava peel and leaf were mixed at ratio 5:1, allowed to ferment using Aspergilus tamari at 10.5 x 108 spurs/gram for five days, after which the mass was sundried to form microbial degraded cassava peel-leaf (MCPL). While the untreated cassava peel and leaf blend was tagged UCPL. Daily feed intake recorded and body weight was recorded for each treatment weekly. At the end of the experiment, blood samples were collected for serum biochemical indices. The results showed that pigs fed MCPL marginally gained more weight compared to pigs on the UCPL and control diets; and that the FCR of pig on MCPL was marginally better than those on other diets. The inclusion of cassava peel-leaf blend with or without microbial degradation had no significant (P>0.05) effect on the serum biochemical indices. It may be concluded that, feeding of microbial degraded cassava peel-leaf blend caused marginal improvement in the growth of pigs with no effect on blood serum biochemical indices.

One hundred and fifty Noiler chicken were used for the eight weeks (56days) study. The birds were infected and were observed to have manifested coccidiosis. After being infected, the birds were randomly allotted into five treatments with thirty birds per treatment. Each treatment has three replicates consisting of ten birds per replicate. T1was left untreated (No Embazin forte or leaf extract) T2were given Embazin forte, T3 were on aqueous extract of Vernonia amygdalina(VA), T4 were on aqueous extract of Carica papaya (CP) and T5 were on mixture of VAand CP(50-50) extract. All birds in each treatment were administered recommended medication and vaccination except coccidiostats. Birds had liberal access to waterand were fed ad-libitum with standard broiler starter and finisher diet at first four weeks and last four weeks of the research. Data on oocyst count, performance and carcass parametersof the noilers were collected. Data performance and carcass parameters were subjected to analysis of variance and significance difference was considered at (P<0.05).Oocyst was not detected for noilers on VA, CP, and VA+CP.VA addition resulted in increased (P<0.001) feed intake (FI) and body weight gain (BWG). Average live weight (ALW) and breast meat weight was increased (P<0.05) with VA administration. Liver and heart weight was not significantly (P<0.05) affected. In conclusion, administration of VA and CP reduced oocyst load and improved performance.

A total of one hundred and fifty day-old Ross broilers were randomly assigned on weight equalisation basis into five dietary treatment groups of thirty birdseach. Each group consists of three replicates comprising of ten birds per replicate. Fivediets were formulated for both starter and finisher phase. Dietary treatments consist of a control diet without ginger and garlic (1:1) mixture (GGM) (T1), while dietsT2, T3, T4 and T5 were control diet supplemented GGM at 0.5, 1.0, 1.5 and 2.0%, respectively. Serum parameterswere determined and lymphoid organ weight was measured on day 56. All data collected were subjected to analysis of variance while trend analysis was carried out using polynomial contrast. Inclusion of 2.0% GGM resulted in increased (P<0.05) serum protein and globulin. Lymphoid organ weight was not significantly (P<0.05) affected. In conclusion, dietary supplementation of GGM resulted inan improved serum proteinvalue of broiler chickens.
