the effect of early feed restriction on performance and serum thyroxin concentration of broiler chickens

an experiment was conducted to evaluate the effect of early feed restriction on performance and serum thyroxin concentration of broiler chicks. the experiment was designed in a 2×2 factorial with 5 replicates of floor pens with 12 male or female chicks in each. 240 male and/or female day-old chicks of a commercial strain (hybrow) were wing banded, weighed and randomly allocated to two treatment...

Effect of Feed Restriction on Performance and Immune Response of Two Commercial Broiler Strains

Effect of Feed Processing on Broiler Performance

It is well recognized that feed represents the most significant cost of broiler production. Most production costs estimates range from 60-70% as being feed costs. Certainly, the major portion of feed costs is for the ingredients used. However, the cost of feed processing represents a significant portion of feed costs and likely gives the greatest opportunity for influencing broiler performance ...

Effect of early feed restriction in male broiler chicks on plasma metabolic hormones during feed restriction and accelerated growth.

1. Plasma GH was greater (P less than 0.05) on day 12 in ad libitum-fed birds compared to restricted chicks. Conversely, maximum GH levels were found to occur in the nutrient restricted chicks during the period of accelerated growth (day 42). 2. A significant decline in circulating insulin concentrations with advancing age was evident in both ad libitum-fed and restricted chicks. 3. Feed restri...
