Effects of dietary curcumin supplementation on seminal quality indices and fertility rate in broiler breeder roosters

British Poultry Science, 2019
1. Decreased semen quality is an underlying contributor to age-related subfertility in broiler breeder roosters. This study investigated the effects of dietary curcumin (derived from turmeric) supplementation as an antioxidant source on semen quality and

Evaluation of Biosecurity in Broiler Breeders

Avian Diseases, 1987
The economic impact of management practices designed to limit the introduction of disease into a parent broiler breeder flock (biosecurity) was evaluated using benefit-cost analysis. Equations were developed to quantify the losses resulting from infection with one of four alternative categories of disease representing incremental levels of ...

Infectious tenosynovitis in broilers and broiler breeders in Egypt

Veterinary Research Communications, 1984
Two infectious tenosynovitis-producing viruses were isolated from tendon sheaths and synovial fluids of 59 broilers and 15 broiler breeders obtained from different flocks in Egypt during June to October 1983. The viruses grew well on the chorioallantoic membrane of developing chicken embryos, produced small localized white pock lesions with oedematous ...

Feeding Broiler Breeders

2002
The feeding and management of table-egg (white and brown shell) breeding birds was not included in this chapter because of the key management differences associated with feeding these breeders as opposed to the methods used for broiler breeders. The feeding of modern table-egg breeders does not require controlled feeding because, in general, the body ...

Comparison of single- and multi-strain probiotics effects on broiler breeder performance, egg production, egg quality and hatchability

British Poultry Science, 2018
1. This study was conducted to investigate the effect of multi-strain probiotic (containing Lactobacillus acidophilus 2.5 × 107 cfu/g, Lactobacillus casei 2.5 × 107 cfu/g, Bifidobacterium thermophilum 2.5 × 107 cfu/g and Enterococcus faecium 2.5 × 107 ...
