Abstract This study evaluated effects of unpeeled sweet potato meal (USPM) on performance of finisher broiler chickens. A total of 180 one day-old broiler chicks were used for the experiment. Brooding operation was carried out for 2 weeks. Thereafter, the broiler chickens were managed for additional 2 weeks with provision of starter diet and water ad-libitum. At four weeks old, they were equalized for weight and distributed into three dietary treatments (control, 10% and 15% unpeeled sweet potato meal as partial replacement for maize) each replicated four times with 15 birds per replicate; laid out in a completely randomized design. The birds were managed intensively throughout the experimental period until they attained 7 weeks of age. Data collected were subjected to one-way analysis of variance. Results revealed that the inclusion of unpeeled sweet potato meal up to 15% in diets of finisher broiler chickens did not significantly affect the growth performance indices, haematological parameters, carcass traits and most of the serum metabolites except albumin which showed significant variation and ranged from 1.35 g/dl (15% USPM) to 1.90 g/dl (control). Least significant cost (N129.73) per kg feed was recorded in birds fed diet containing 15% USPM relative to highest cost (N136. 63) per kg feed observed in birds fed control diet. Conclusively, incorporation of unpeeled sweet potato meal up to 15% in diet of finisher broiler chickens reduced cost per kg of broiler finisher diet and had no detrimental implications on growth performance, haematological parameters, serum metabolites and carcass traits in chickens.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Intestinal Lesion

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.
