Title: Effect of spice-treated sundried bovine rumen digesta on performance, carcass characteristics and nutrient digestibility of finisher broiler chickens Authors: Eniwaiye, Adenike A; Otu, Bisong O.; Kolo, Philip S.; Owolabi, Shina J.; Balogun, Muda A.; Ochiyan, Michael A. Abstract: The study was conducted to investigate the effects of feeding diets containing spice treated Sundried Bovine Rumen Digesta (SDBRD) on growth performance, carcass characteristics and nutrient digestibility of broiler chickens. A total of one hundred and fifty (150) day old broiler chickens were assigned to five (5) diets in triplicates containing ten (10) birds each in a completely randomized design. The diets were; T1, (control, 0% SDBRD), T2 (20% SDBRD without spice supplementation), T3 (20% SDBRD + 200 mg ginger), T4 (20% SDBRD + 200 mg garlic), and T5 (20% SDBRD + 200 mg thyme). Data were collected on growth performance, carcass characteristics and nutrient digestibility. The data were analysed using the Analysis of Variance (ANOVA) and differences among mean were separated with the Duncan Multiple range. The results showed that broiler chickens fed diets containing spices-supplemented SDBRD had significantly (p<0.05) higher weight gain and better feed conversion ratio (FCR). The live weight and dressing percentage were significantly (p<0.05) higher among birds fed spice-supplemented diets compared to the control and the un-supplemented SDBRD diet. However, digestibility for dry matter and crude protein was higher (p<0.05) on T1 and T2 than on spice supplemented diets. It was concluded that the combination of sundried bovine rumen digesta and spices such as garlic, ginger and thyme improve growth performance, carcass characteristics and nutrient digestibility, and can therefore be included in the ratio of broiler finisher at 20% level without any deleterious effect.

Title: Growth performance of broiler chickens fed diets containing four different oil types at starter phase Authors: Otu, Bisong Okpata; Kudu, Yahaya; Kolo, Philip; Banjo, Adenike; Henry, B. C; Okon, J Abstract: The growth performance of broiler chickens fed diets containing four different oil types at starter phase was investigated. One hundred and eighty (180) day old ROSS 308 chicks of mixed sexes were allotted into five (5) treatments, replicated three times, with twelve (12) birds per replicate, in a Completely Randomized Design (CRD). Five diets were formulated as T1 (0% oil), T2 (4 % Palm oil), T3 (4% Palm kernel oil), T4 (4% Groundnut oil) and T5 (4% Shear butter oil) and fed to the broiler chicks throughout the experimental duration of four (4) weeks. The resultsshowed that final body weight, body weight gains and weekly feed intake were significantly different (P<0.05) between treatments. Initial body weight, feed conversion ratio, protein and energy efficiency ratios were not significantly different (P>0.05) between treatments. The highest final body weight (237.43 g), body weight gain (189. 70 g) and weekly feed intake (155.45 g)wererecorded in T5. The range of values of 46.47 g (T1) – 47.73 g (T5), 3.19 (T1) - 3.47 (T3), 1.39 (T3) – 1.49 (T2) and 0.09 (T3 and T4) – 0.10 (T1, T2 and T5) were recorded for initial body weight, feed conversion ratio, protein and energy efficiency ratios, respectively. The study concluded that the four types of oil do not have equal effect on the various growth parameters of the broilers in spite of the fact that the oil types were added at the same levels in the diet. However, it is right to suggest that shear butter oil inclusion will produce better growth performance without any deleterious effect.

Title: Growth performance and gut microflora counts of Ross 308 broiler chickens fed probiotic based diet at the starter phase Authors: Eniwaiye, Adenike Adetutu; Alabi, Olushola; Lawal, Babatunde; Owolabi, Shina James Abstract: This study was conducted to evaluate the effect of probiotics on growth performance, nutrient digestibility, and gut microflora of broiler chicken at the starter phase. A total of thirty (30) broiler chickens were randomly allotted to five treatments groups, with each group consisting of three replicates with each replicate containing two chickens. The treatments were as follows: T1 (control no probiotics), T2 (5.50g of oxytetracycline), T3 (6.25g of probiotics), T4 (12.50g of probiotics) and T5 (18.50g of probiotics). Data were collected on growth performance, nutrient digestibility, and gut microflora counts. The results indicated a significant (P<0.05) difference on total and daily feed intakes while the final weight, total weight gain, daily weight gain and feed conversion ratio were not significantly (P>0.05) different among dietary treatments. For the nutrient digestibility, dietary treatment had significant effect (P < 0.05) on crude fibre, ash, and ether extract while there were no significant (P>0.05) differences on crude protein, nitrogen free Extract, dry matter, and total digestible nutrient. Findings on the gut microflora showed that there was no significance (P>0.05) difference in Lactobacillus sp. (LS), Pediococcus acidilactici (PA), Streptococcus acidophilus (SA), Escherichia coli (EC), Streptococcus pneumoniae (SP), Bacillus cereus (BC) across all treatments. It was concluded that the addition of probiotics to broiler diets could improve feed intake and nutrient digestibility. Hence poultry farmer should include it in their broiler chicken diets at the starter phase at 6.25g to enhance fast growth rate in broiler chicken.

Title: Response of Broiler birds fed diets containing varying levels of dried watermelon rind (DWMR) at finisher phase. Authors: Otu, Bisong Okpata; Banjo, AdenikeAdetutu; Kolo, Philip Sodi; Ibrahim, Abdulsalam Dabban Abstract: A feeding trial was conducted to investigate growth performance and nutrient digestibility of experimental diets formulated with dried watermelon rind to replace wheat offal, fed to broiler chickens at finisher phase. One hundred and fifty day-old “ROSS 360” broiler chicks were randomly allotted to five dietary treatments of thirty (30) birds per treatment. Each treatment was replicated three times with ten birds per replicate in a Completely Randomized Design (CRD) arrangement. Five experimental diets containing dried watermelon rind at varying levels of replacement were formulated and designated as T1, T2, T3, T4 and T5 with replacement levels of 0 %, 25 %, 50 %, 75 % and 100 % respectively. Initial body weight, final body weight, body weight gain, feed itake, feed conversion ration and apeparent digestibility of crude proten, fibre, ash and nitrogen free extract were measured. There were no significant (P>0.05) differences among the treatment groups for all the growth parameters except for feed conversion ratio. Final weight ranged from 1223.33 to 1305.19 g; while daily feed intake, daily weight gain and feed conversion ratio ranged from 89.46 to 97.95 g, 35.26 to 38.25 g and 2.35 to 2.78, respectively.. The nutrient digestibility indicates significant (p<0.05) difference in crude fibre, ash, ether extract and NFE, while that of crude protein, dry matter and total digestible nutrient were not significantly (P>0.05) different. Crude protein, dry matter and TDN ranges between 67.47 % to 69.15 %, 79.10 % to 80.72 and 74.35 to 78.68 respectively. The study concluded that 25 % replacement of wheat offal with dried watermelon rind can be effective for optimal growth performance and complete replacement for fibre and energy requirement in producing broiler chickens without compromising performance or any deleterious effects.
