Effects of Broiler Breeder Age on Egg Quality, Incubation Performance, and Early Progeny Physiological and Muscle Fiber Development

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of breeder hen age on the incubation performance, embryonic development, and progeny quality of Cobb500 broiler breeders at 39, 51, and 69 weeks of age. A total of 870 eggs were collected, of which 810 were incubated; these were assigned to a completely randomized design with three treatments and nine ...

Effects of Dietary Activated Charcoal Supplementation on Performance, Egg Quality, and Bone Calcification in Laying Hens Exposed to High Fluoride

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The aim of the present study was to determine the effects of high dietary fluoride intake on performance, egg quality, serum biochemical parameters, bone tissue, mineral accumulation, and the expression of selected mineralisation‐related genes in laying hens, and to evaluate whether these effects could be alleviated by dietary activated ...

Significance of chick quality score in broiler production

animal, 2012
The quality of day old chicks is crucial for profitable broiler production, but a difficult trait to define. In research, both qualitative and quantitative measures are used with variable predictive value for subsequent performance. In hatchery practice, chick quality is judged on a binomial scale, as chicks are divided into first grade (Q1-saleable ...

Evaluation of Torula Yeast (Candida utilis) Single Cell Proteins as a Partial Replacement for Soybean Meal in Broiler Diets: Effects on Productive Performance, Meat Quality Traits, and Plasma Metabolome

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Over recent years the use of yeast in feedstuffs has gained momentum due to novel developments in single‐cell proteins (SCPs). SCPs are considered a sustainable protein source, as their production enable to convert low‐value substrates (including industrial/agricultural wastes) into feed, with a related reduced environmental impact.

Management factors resulting in a severe reduction in feed intake–induced spiking mortality syndrome in young broiler chicks

Poultry Science, 2020
This study aimed to induce spiking mortality syndrome (SMS) in 10-day-old broiler chicks by changing feed particle size (crumble feed to pellet feed) and/or feed source location (from a small feeder at the pen's center to a large feeder at the front of ...
