Interaction of Feeding Time and Temperature and Their Relationship to Performance of the Broiler Breeder Hen

摘要: Abstract Experiments with broiler breeder hens were undertaken to determine effect of feeding time and environmental temperature on various production variables, body weight, feed consumption. Two treatments used: low cyclic (10 25 C), high (21 39 C). The three were: fed one daily meal either at 0700 h (Treatment 1) or 1800 2), one-half the amount other half 3). In another experiment, assigned times h. Feeding did not markedly affect rate egg production; however, two meals per day produced fewest eggs. High caused significant reductions in specific gravity, shell thickness. had no oviposition, ovulation, transit through oviduct. Significant weight loss occurred Both a reduction
