Meta-analysis of factors that affect nutrient requirements in laying period of broiler breederhens. Part 2: Developing Performance prediction models

摘要

Implications Predicting the effect of environmental variables and management conditions on performance of broilerbreeder flocks is a hard challenge because the conversion of feed into breeder’s product has large influence on the cost ofproduction.Introduction Sauvant et al. (2008) explained the importance of periodically requiring quantitative summarizations ofanimal nutrition literature data by processing and modelling of databases because in animal sciences especially in the fieldof nutrition the number of publications in each filed of research is increasing. Current meta-analysis was conducted todevelop performance prediction models according to dietary nutrients intake and considering environmental variables andmanagement conditions for breeding period of Ross 308 broiler breeder hens.
