Distillers Dried Grains With Solubles: Determination Of Metabolizable Energy Values Using Regression-Based Assays And Their Correlation With Chemical Composition, Kenia Mitre
Graduate Theses and Dissertations
The inherent variability and lack of standardization of in vivo assays to determine the metabolizable energy (ME) of DDGS has led to inconsistent values and limited its potential to use in broiler diets. Therefore, two experiments were conducted to characterize the content of nitrogen-corrected ME (MEn) in 11 DDGS sources obtained from various ethanol plants using a regression-based broiler assay and to attempt to develop equations to predict MEn based on its chemical composition. In experiment 1, the objectives were to determine the influence of inclusion level and feed intake on the resulting ME and MEn values of a single …
Nutritional Strategies For Feeding Broiler Breeders On Hen And Progeny Performance, Antonio Beitia
Nutritional Strategies For Feeding Broiler Breeders On Hen And Progeny Performance, Antonio Beitia
Graduate Theses and Dissertations
Over the last 60 plus years, broiler breeders have been under an incredible amount of genetic pressure. This genetic pressure comes from the continually increasing consumer demand for poultry products. The objective of this dissertation is to understand the effects of different nutritional and management practices on broiler breeder’s performance. The first series of experiments investigate the impact of broilerization on hen and early progeny performance. Broilerization is a process only used by genetic companies. The results from these experiments showed the adverse effects of broilerization on chick quality and hen performance. Follow up trials were performed to determine the …
