The balancing of digestive tract microbe can improve the health broiler chickens. Fermented lime waste flour (FLWF) contains citric acid, which decrease pH value to suppress pathogenic bacteria development and lactic acid growth in small intestine broiler. purpose study was evaluate effect using FLWF on microbial This used 200 female research a completely randomized design with four treatment l...

the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. in this experiment, 192 day old female ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 replications. dieta...

Hot climate is a major limiting factor of broiler production in tropical and subtropical regions. The use of standard stocks in hot climates may result in large economic losses because genotypes selected in temperate climates may respond differently to the high ambient temperatures in hot regions or seasons. The summer and fall in Izmir, Turkey, provided the natural hot and temperate climates, ...

Two studies were conducted to determine the response of late-developing broiler males and females to dietary Lys from 42 to 56 d of age. Hubbard Ultra Yield males and females were placed at separated ends of a floor pen broiler house and raised on common diets. At 42 d of age, broilers were then fed 1 of 7 gradient concentrations of dietary Lys that progressively increased by 0.07% from 0.68 to...

This study was conducted to determine whether early age feed restriction improves heat tolerance in female broiler chickens. Chicks were brooded for 3 wk and then maintained at 24+/-1 C. On Day 0, chicks were assigned to one of four feeding regimens; each regimen was applied to four cages of chicks. The feeding regimens were 1) ad libitum feeding (ALF); 2) 40% feed restriction at 4, 5, and 6 d ...

background: according to literature, there are differences among different species of animals in respect to absorption of d-xylose. objectives: in two experiments, the differences that might exist in absorptive capacity of small intestine for d-xylose, in different types of chicken were tested. methods: in experiment one, 2 groups of nine adult layer type males (48 weeks) and females (58 weeks)...

The aim of this study was to evaluate different feeding schedules and their relationship to calcium (Ca) and phosphorus (P) plasma levels and egg quality of broiler breeders. The feeding schedules were: single feeding at 8:00 AM; twice daily feeding (50% at 8:00 AM and 50% at 3:00 PM) and single feeding at 3:00 PM. 330 female and 45 male Cobb 500 broiler breeders were used from 40 to 60 weeks o...

This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0....

The aim of this study was to investigate the presence of antibodies to ALV-J in broilers and broiler breeders. For this, 5 broiler units and 1 broiler breeding unit in the Marmara region were visited. Seventy 4-6 -week-old chicks from the broiler units, consisting of 14 chicks from each broiler unit, were selected. Seventeen chickens from the broiler breeding unit were also selected. The chicks...
