The feeding dynamics of broiler chickens.
Contrary to a commonly held belief that broiler chickens need more space, there is increasing evidence that these birds are attracted to other birds. Indeed, commercially farmed birds exhibit a range of socially facilitated behaviours, such as increased feeding and preening in response to the presence of other birds. Social facilitation can generate feedback loops, whereby the adoption of a par...
متن کاملEffects of Canola Bioactive Peptides on Performance, Digestive Enzyme Activities, Nutrient Digestibility, Intestinal Morphology and Gut Microflora in Broiler Chickens
The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...
متن کاملPerformance, Carcass Characteristics and Immune Responses of Broiler Chickens Subjected to Sequential or Wet Feeding Programs Subsequent to Early Meal Feeding Regime
The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...
متن کاملEffects of concanavalin A on intestinal brush border enzyme activity in broiler chickens.
1. The effects of Concanavalin A (Con A) on enzymes from the intestinal brush border were studied using membrane vesicles (BBMV) prepared from 3- and 6-week-old broiler chickens. 2. Maltase, sucrase, phytase, alkaline phosphatase and leucine aminopeptidase activities were assayed in BBMV in the absence (T0) or presence (T1) of Con A, or in the presence of casein (T2). Disaccharidase specific ac...
متن کاملevaluation of the feeding value of waste fig, with and without enzyme supplementation, in broiler chickens
two experiments were conducted to investigate the feeding value of waste fig along with its effect on broilers, performance. in the first experiment, the amen content of fig was determined through total collection method using 10 adult leghorn cockerels. in the second experiment, 240 day-old male ross broiler chicks were randomly alloted to 6 experimental groups of 4 replicates of 10 chicks eac...
