Reduction Of Protein Levels In Broiler Feed For Commercial Application – A German Case, Andreas Lemme, Kilian Fenske, Heiner Westendarp, Mathias Guhe, Elmar Rother
Proceedings of the Arkansas Nutrition Conference
A project was initiated to apply dietary CP reduction under commercial conditions. The main objective was to demonstrate and validate that dietary CP can be reduced without compromising broiler performance in a production system which is already rather efficient. In addition, we wanted to demonstrate the potential of dietary CP reduction on reducing N-excretions especially in the context of German revised regulations and monitoring attempts. Finally, as previous research suggested, few further aspects such as impact of dietary CP reduction on litter quality and quantity, footpad health, change of ingredient inclusion levels and related impact on sustainability impact factors were …
Amino Acids Were Not All Created Equal, Peter H. Selle, Shemil P. Macelline, Peter V. Chrystal, Sonia Y. Liu
Amino Acids Were Not All Created Equal, Peter H. Selle, Shemil P. Macelline, Peter V. Chrystal, Sonia Y. Liu
Proceedings of the Arkansas Nutrition Conference
The contention that amino acids were not all created equal is based on the simple premise that intestinal uptakes of non-bound (synthetic, crystalline, feed-grade) amino acids are more rapid than their protein-bound counterparts. The post-enteral ramifications of this difference in bioequivalence are amplified in broiler chickens given their express growth rates and just one complication is the post-prandial oxidation of amino acids. The lack of bioequivalence between non-bound and protein-bound amino acids is a real obstacle to the development and adoption of reduced-crude protein diets that have the potential to promote sustainable chicken-meat production Thus, the purpose of this paper …
A Dynamic Approach To Feed Formulation, Rob Gous
A Dynamic Approach To Feed Formulation, Rob Gous
Proceedings of the Arkansas Nutrition Conference
The objective of this paper is to demonstrate that the opportunity cost of using fixed tables of nutrient requirements when formulating feeds for broilers can be considerable, and that nutritionists should consider a more dynamic approach to defining the lower bounds of amino acids in particular, in line with the objective of the business, which is to maximise profit. In order to do this, it is necessary to consider the potential growth rate of the broiler, the cost of feed and amount of feed consumed, and the income generated from the sale of product.
