 Male and Female Anak strain of broilers were raised on deep litter to investigate the effect of separating the sexes at the finisher phase on growth performance, carcass characteristics and breast muscle development between the sexes. The day-old chicks were raised as mixed sexes for four weeks starter period. Thereafter, 108 of the starter birds were distributed into three sex groups - male, female and mixed, each group replicated thrice and uniformly fed finisher diet for six weeks. The birds .were individually weighed weekly, Six birds representing each sex from each group were dissected at week 10 to compare performance in terms of external body parts, internal organs, fat depot, leg bones and breast muscles. There were no significant differences (P>0.05) between male and female of either sex groups in weekly body weight gains, feed consumption, utilisation, weight of breast muscles, internal organs, and fat deposit. Coefficient of variation was higher in male than female. Percentage male superiority was higher when the birds were raised as separated sexes than mixed. Male broilers raised as separate sex had significantly (P<0.05) heavier neck and thigh than the female, while in the mixed sex group, the male was significantly (P <0.05) higher than the female in back, breast, wing and tibia weights. Males in both sex groups recorded significantly (P<0.05) heavier head, drumstick, shank and femur. The result from this study has shown that there is no statistically significant advantage for separating the broiler chickens into sexes as a management practice during the finisher phase.

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.
