in this experiment 240 hy-line (w-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. the amounts of watermelon skin meal (wsm) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. the results showed that using wsm up to 2% significantly improved the performance and...

A study was carried out to the effects of Ginger (Zingiber officinale) on quail semen quality, sexual hormones levels and histology testicles. total number 108 birds at age 8 weeks were divided into four groups, with three replicates per treatment 9 replicate. Birds in control group fed basal diets groups diet supplemented 0.25, 0.50 0.75% Ginger. At ages 10 till 20 weeks, blood samples collect...

A feeding trial was carried out to investigate the effects of lecithin on growth performance, nutrient digestibility, lipid profile, carcass characteristics and meat quality of broiler chickens. A total of 240 oneday- old male broiler chicks (Cobb 500) were obtained from a local hatchery and raised for 42 days. The chicks were divided into 5 dietary treatments. The diets supplemented with prill...

A 28-day feeding trial was conducted to evaluate the effects of dietary inclusion of Neem (Azadirachta indica) leaf meal on the haematological and serum biochemical indices of starter broilers. The Neem leaves used in the experiment were manually harvested, air-dried and milled to become Neem leaf meal. The Neem leaf meal was included in broiler starter diets at 0, 2.5, 5.0, 7.5 and 10% levels,...

Phytate is not only an unavailable source of phosphorus (P) for broilers but it also acts as an anti-nutrient, reducing protein and mineral absorption, increasing endogenous losses and reducing broiler performance. The objective of this study was to investigate the anti-nutritional effects of phytate by including high levels of phytase in diets not severely limited in available P. A total of 76...

Although Salmonella is a major problem in poultry food safety, it is believed to be of minor concern for broiler production in regard to animal performance. To determine the effect of Salmonella challenge in broiler chickens, 2880 male Cobb 500 birds derived from a commer­ cial hatchery were evenly distributed over 48 floor pens resulting in 60 birds per pen. Litter was 50% new wood shavings an...

Necrotic enteritis is an enteric disease of avian species caused by the anaerobic bacterium Clostridium perfringens. The disease is regularly controlled in the broiler chicken industry with antimicrobials in feed but is reemerging in areas such as Europe where there is a ban on antimicrobials as growth promoters. To study prospective therapies, researchers must be able to reproduce this disease...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal sciences university poultry farm to find out the effects of different oils on productive performance of broilers. the chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. each treatment had 150 birds, with...

This research was conducted to investigate the effects of coriander ( Coriandrum sativum ) essential oil nano emulsion (NCSEO) in drinking water on growth performance and intestinal health (intestinal microbiota histomorphology) broiler chickens. A total 180 one-day-old male chickens were randomly allocated into five treatments with four replicates 9 chicks per replicate pen. Birds provided NCS...
