Table1_Metformin modulates the gut microbiome in broiler breeder hens.docx [PDF]

, 2022
Broiler breeder hens, the parent stock of commercial broiler chickens, are genetically selected for rapid growth. Due to a longer production period and the focus of genetic selection on superior carcass traits in their progeny, these hens have the ...

Is relaxing broiler breeder growth restriction cost-effective?

Poultry Science, 2023
: Broiler breeders are subjected to feed restriction programs to control excessive growth. However, current levels of feed restriction and concomitant growth restriction are becoming severe, raising welfare and suboptimal reproductive performance ...

Comparison of Dwarf and Normal Broiler Breeder Hens

Poultry Science, 1985
Two strains of dwarf and two of normal broiler breeder hens were compared during the laying period for the following production parameters: egg number, hen-day and hen-housed egg production, mortality, feed consumption, egg weight, egg shell quality, hatchability, and fertility.

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Effects of breeder hen dietary Saccharomyces yeast postbiotic supplementation on progeny growth performance, body morphometrics, carcass yield – an industry-academic collaboration

Journal of Applied Poultry Research
Summary: As the world continues to grow in population and economic wealth, the demand for animal-derived protein continues to grow exponentially. With poultry being the second most animal-derived protein in the world, producers must become creative in ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Effect of early photostimulation at 15-weeks of age and everyday spin feeding on broiler breeder performance

Poultry Science, 2022
To prevent broiler breeders from growing too quickly and becoming too large for optimum reproduction, their dietary intake is restricted. While current restricted feeding programs, such as skip-a-day feeding (SAD), improve the economic efficiency of ...

Calcium Requirements of Turkey Breeder Hens

Poultry Science, 1964
Abstract LITTLE information is available on the effects of excess calcium on breeder chickens or turkeys, although Berg et al. (1962) have shown that 2.75 or 3.25% calcium in the diets of young chicken hens significantly depressed hatchability of eggs as compared with eggs from pullets fed 1.75 or 2.25% calcium.

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.
