this experiment was conducted to determine the effects of either twice or thrice a day feeding regimens on performance and as well on plasma hormone and metabolite levels of broiler breeder hens during 24 to 38 wk of their productive age. breeder pullets were provided form a commercial flock, and distributed in experimental units, in a compeletly randomized design with three feeding regimens (t...

Canistel (Pouteria campechiana) is an underutilized fruit tree species found in many parts of the world. The objective of this study was to evaluate suitability of canistel fruit meal (CFM) as a feed ingredient for broiler chickens. Giving completely randomize design, ninety broiler chickens in 30 floor pens received one of five diets ad libitum from day 21 to 42. The nutritionally balanced con...

We investigated the effects of dietary supplementation of zinc (ZnO; 0, 40, 80, 120 and 160 mg/kg) and Vit E (α-tocopheryl acetate; 0 and 40 IU/kg) on egg production, egg quality and Zn content of egg fractions and tissues in Japanese quails. Using a 5 × 2 factorial design, a total of 960 Japanese quails (Coturnix coturnix japonica) at day 70 of age were housed in cages and randomly assigned in...

In a 42-d experiment, 576 one-day-old Vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and Bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. The inclusion of Bio choline and lecithin extract in the diet signifi...

This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments...

The effect of Aspergillus xylanase (ASXYL) supplementation to maize-soybean diets on serum aspartate aminotransferase, serum alanine aminotransferase, microbial examination, growth traits, carcass characteristics and meat quality traits of broiler chickens was investigated. Three hundred one-day-old mixed sex “Cobb 500” broiler chicks were allotted to 5 dietary treatments with 5 replic...

A study was conducted to determine the effects of corn distillers’ dried grain (CDDG) on the performance and egg quality of laying hens. The hens were fed dietary inclusions of CDDG at 0, 10, 20, 30 and 40% for a period of eight weeks. Average feed intake, weight gain, feed conversion ratio and nitrogen economy varied significantly (P<0.05) among dietary treatments. Birds fed 30% dietary CDDG h...
