Iron requirements of broiler breeder hens

Poultry Science, 2017
A study was conducted to investigate Fe requirements of broiler breeders. One-hundred-fifty-six Cobb 500 broiler breeder hens were individually placed in electrostatically painted cages at 22 weeks. The study was composed of an adaptation phase, in which hens were fed corn-soy-wheat bran diets until 35 wks.

Nutritional Characterisation of Acheta domesticus at Different Developmental Stages for Application in Animal Feed

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The house cricket Acheta domesticus has emerged as a promising alternative protein source for animal nutrition; however, limited information is available on how developmental stage influences its nutritional characteristics. This study compared subadults (30‐day‐old) and adults (40‐day‐old) crickets in terms of chemical composition, mineral ...

The Chloride Requirement of the Broiler Breeder Hen

Poultry Science, 1984
An experiment was conducted to determine the chloride requirement of broiler breeder hens fed a corn soybean meal diet. Levels of .135 and .09% (daily intake of 208 and 139 mg) supplemental chloride were required for maximum egg production and egg weight, respectively. However, a supplemental level of .135% was required to maximize hatchability.

Guanidinoacetic Acid Improves Growth Performance and Gut Health of Broilers Fed Metabolizable Energy‐Reduced Diets

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to evaluate the effects of guanidinoacetic acid (GAA) supplementation to diets with different energy levels on growth performance, carcass traits, and gut health status in broiler chickens. A total of 9500 1‐day‐old Ross 308 broilers (equal numbers of males and females) were allocated to 1 of 5 dietary treatments (10 ...

Applied Research Note: Maternal flaxseed diet did not affect body weight of broiler chickens diagnosed with novel avian reovirus and infectious bronchitis

Journal of Applied Poultry Research
SUMMARY: Feeding breeder hens diets enriched with omega-3 fatty acids (n-3 FA) has previously been shown to increase their progeny's immunocompetence. During an experiment to assess the effects of maternal-fed n-3 FA on broiler behavior, broiler chickens
