Body Weight and Food Intake of Broiler and Leghorn Chicks
Age of market weight of broilers has been continuously reduced by approximately one day per generation during the past 40 50 years due to an average increase of 50 g/year of body weight at 42 days of age (Gyles, 1989). Although non-genetic factors such as improved feeding and management contributed to this growth rate increase, genotypic selection for growth seems to be the major cause (Chamber...
متن کاملThe Effects of Sodium Humate and Aflatoxin B1 on Body Weight of Broiler Chicks
The objective of this study was to investigate the protective effect of dietary natural sorbent-sodium humate (HuNa) on the prevention of aflatoxin B1 (AFB1) toxicity in the broiler chicken. Seventy-two (72) broiler hybrid Hybro birds were randomly divided into 4 groups: control group (G1) and 3 experimental groups (G2-G4) with addition of HuNa (G2); only AFB1 (G3) and HuNa; and AFB1 (G4). HuNa...
متن کاملDietary glycine needs of broiler chicks.
Dietary Gly might become a limiting factor in all-vegetable diets fed to broiler chicks when low CP is formulated in combination with marginal levels of dietary Thr and Ser. A study was conducted to evaluate dietary Gly needs of broiler chicks. Day-old Ross 508 male chicks were placed in 32 floor pens (15 chicks/pen). Chicks were fed a common prestarter diet from 0 to 7 d of age and then fed a ...
متن کاملEarly lysine deficiency in young broiler chicks.
The carry-over effect of a pre-starter diet (0 to 3 days of age) deficient in lysine on subsequent growth and body composition (3 to 10 days) was examined in two experiments on male broiler chicks raised in cages. In experiment 1, lysine deficiency was applied from 3 to 10 days after providing a balanced pre-starter control feed (D+, 1.40% lysine) or a lysine deficient feed (D-) during the firs...
متن کاملEarly age thermal conditioning immediately reduces body temperature of broiler chicks in a tropical environment.
Early age thermal conditioning (TC) durably improves resistance of broilers to heat stress and reduces body temperature (Tb). Three experiments on broiler chicks were conducted to evaluate the effects of TC at 5 d of age on Tb variation measured by thermometer between 4 and 7 d of age, under a tropical environment. Because manipulation of chickens to measure Tb with a thermometer may increase T...
