Dry matter and calcium content of the digestive tract were determined on two groups of broiler breeders during a 24-hr period. The individually caged hens were fed either ad lib or restricted to 122 g of feed during a 4-hr feeding period each day from 0700 to 1100 hr. The hens received artificial light from 0700 to 2300 hr. On Day 14 of the feeding program(More)
Live performance and skin characteristics of male and female broilers were evaluated under four coccidiostat feed additive programs. Treatments consisted of halofuginone (H) and salinomycin (S), fed either continuously (HH and SS) or in rotational programs (HS and SH) during the starter (1 to 21 d) and grower (22 to 35 d) periods, respectively.

Two independent field trials were undertaken with commercial broiler companies in separate sections of Alabama in order to test the efficacy of an experimental commercially prepared oil emulsion infectious bursal disease (IBD) vaccine in broiler breeder pullets. The IBD vaccine was tested both for safety and the production of neutralizing antibodies in(More)
The safe and effective use of chemicals within the live production phases of the poultry industry requires the implementation of integrated health programs. Chemical programs will vary with regard to phase, intended usage, and method and frequency of application. The term "chemicals" herein presented excludes drugs and non-nutritive feed additives, with(More)
The objectives were: 1) determine whether enzymes improve DMD or NDFD, and 2) establish whether increased digestibility was due to feed-treatment effect or an enhancement of the hydrolytic capacity of the ruminal fluid. Two cannulated lactating Hol-stein cows were fed a sequence of four TMR: no enzymes (-E), enzymes added to the concentrate portion of the(More)
Experiments were conducted to determine the influence of time of dietary calcium intake on eggshell quality in broiler breeder hens. In Experiment 1, 60 hens were randomly divided among three treatment groups. The control group received 155 g feed (3.1% calcium) per day at 0800 hr whereas the morning- (a.m.) and evening-fed (p.m.) treatments received a .42%(More)
