INTRODUCTIONGenetic selection programs emphasizing broiler growth, breast muscle deposition, and feed efficiency traits over the past 30 yr have led to a rate of change that has not slowed (Havenstein et al., 2003a,b). Photostimulation (PS) age, feed allocation, and BW profile of the maturing pullet can all effect nutrient partitioning between growth and ovary development (Robinson et al., 2007). ...

INTRODUCTIONHeritage chickens are important for breeders and industry to protect valuable genes and traits over the long term. However, 50% or more of the genetic diversity is absent in commercial pure lines (FAO, 2007; Muir et al., 2008). Therefore, preserving potentially valuable genes by conducting research with heritage breeds is important. Changes in live weight and proportional growth of bod ...

INTRODUCTIONAwareness about the importance of maternal diet on offspring health is increasing. Maternal nutrition is being studied in livestock species as a way of improving offspring growth and production (Rehfeldt et al., 2011; Long et al., 2012; van Emous et al., 2015b). The poultry industry is constantly working to increase carcass yield and obtain a fast growing broiler, and manipulation of m ...

INTRODUCTIONOmega-3 polyunsaturated fatty acids (n-3 PUFA), mainly eicosapentaenoic acid (EPA, 20:5 n-3), docosahexaenoic acid (DHA, 22:6 n-3) and alpha-linolenic acid (ALA, 18:3 n-3), are suggested to reduce the risk of cardiovascular diseases and certain forms of cancer, as well as to improve brain development and function. Due to compelling evidence supporting the health benefits of n-3 PUFA co ...

Nutrient Requirements A nutritionist’s goal is to match nutrient supply to the nutrient requirements of the flock. Therefore, feed allocation decisions for broiler breeders are driven by nutrient requirements. Ideally, feed would be allocated according to the needs of every bird. In reality, flock managers must still make feed allocation decisions according to the average bird.Classically, a ...

Managing broiler breeders is a new challenge with every flock as breeder companies produce new and improved "models" that have better growth efficiency and productivity than the year before. At the same time producers have been getting better at raising highly uniform flocks. All this progress means that the way we have allocated feed in the past might not be the most effective way to feed new and ...
