Reproductive toxicity of roundup®-treated feed on broiler breeder roosters and the amelioration of these deleterious effects with inclusion of humic acids in feed.

open access: yesVeterinary and Animal Science, 2021
Glyphosate-based herbicides (GBHs) such as RoundUp® are a staple of modern crop production, and as a result, residues of their ingredients are typically found in animal feeds.

Sodium Chloride for Broiler Breeders

open access: yesPoultry Science, 1983
Two experiments, each of 224 days duration, were conducted with Cobb broiler breeders, 32 weeks of age, to determine their response to supplemental dietary sodium chloride levels ranging from .12 to .48% in a corn-soybean meal diet. Average hen-day egg production, daily feed intake, feed required per dozen eggs, and egg specific gravity were not ...

Restricted Feeding of Broiler Breeders

open access: yesPoultry Science, 1983
Two experiments were conducted to compare the effects of various feed restriction programs during the growing and laying periods on body weight, egg production, fertility, and hatchability. In the first experiment, Cobb color-sexed broiler breeders were fed one of three grower programs (full feed, skip-a-day, or low protein) from 8 to 24 weeks of age ...

Optimizing the health of broiler breeder birds

open access: yes, 2022
The main objective in broiler breeder production is to produce fertilized eggs resulting in healthy and robust day-old broiler chicks. Due to the continuing increase in the genetic potential of the offspring and the improved reproduction performance ...

Water Usage of Broiler Breeders

open access: yesPoultry Science, 1989
Water usage of daily fed and skip-a-day-fed broiler pullets housed in cages was measured in two trials. Daily fed birds in both trials had free access to water. In Trial 1, skip-a-day-fed birds were restricted to 4 h water every day or only on feed days. In Trial 2, the skip-a-day-fed birds were water restricted 4 h either every day, only on feed days,

Gut capacity of broiler breeder hens

open access: yesBritish Poultry Science, 2021
1. Broiler breeders are subjected to qualitative or quantitative feed restrictions to prevent obesity, which causes major health and welfare problems. Diluting their feed by adding inert or low nutrient, bulky materials can reduce obesity, but the capacity of the gut needs to be determined to apply this strategy successfully.

Housing and management of broiler breeders and turkey breeders.

open access: yes, 2012
AbstractThis chapter describes the housing and management of broiler breeders and turkey breeders in Europe. The majority of broiler breeders in Europe are the standard, fast growing genotype, but 18-20% of the broiler breeders are dwarf parental females that produce standard and alternative (medium or slow growing) broilers.
