Restricting Growth of Broiler Breeder Pullets

Poultry Science, 1969
Abstract Restricting rate of gain and delaying sexual maturity of pullets are important considerations in producing a profitable broiler breeder flock. Most of the existing programs for rearing broiler pullets are based on some type of feed restriction, or the use of diets designed to limit nutrient intake starting around 8 to 10 weeks of age ...

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Reduction of Ribonucleotide Reductase Subunit RRM2 Potentially Impairs Gut Function of Woody Breast Broilers

Animal Research and One Health, EarlyView.
Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...
