Overall objectives
Development of nutritional concepts for EM and IC.
- To meet nutritional requirements of EM and IC innovative nutritional concepts are needed ,
- To reduce boartaint
- To compensate alterations of intramuscular fat (IMF) content and fatty acid composition
IPEMA will aim at nutritional recommendations for feeding EM and IC, in close collaboration with other scientists involved in the project. For EM, the challenge is to develop optimized recommendations for dietary energy, amino acids, fatty acids and other components which aim at efficient growth, efficient dietary control of the boar taint compounds and optimized technological and sensory pork quality. The objective for IC is to propose nutrient requirements which take into ac- count the specific characteristics of the two metabolic phases, with regard to protein deposition and feed intake.
Subtasks WG2
- Development of optimized recommendations for dietary energy, amino acids, fatty acids and other components which aim at efficient growth
- Definition of nutrient requirements for IC, which take into account the respective length of the two metabolic phases, prior and after the second vaccination. Definition of extra nutrition (energy and protein) requirement need for entire male pigs vs. gilts and castrates.
- Efficient dietary control of boar taint compounds (with WG1)
- Feeding strategies for optimized technological and sensorial properties of pork
Specific Objectives for the second Grant Period (May 2017 - April 2018)
- Identification of approaches for standardization of test conditions to improve prediction of boar taint potential to work on recommendations for rearing conditions in breeding programmes (together with WG 1 - Genetics and WG 3 - Management and Housing)
- Evaluation of current research projects to identify the most important knowledge gaps in the field of nutrition of entire males and immunocastrates
- Identify established feeding strategies and feed additives which allow both, to realize the high growth potential and the lower nitrogen and phosphorus excretion of entire male and immunocastrated pigs, and to reduce boar taint levels in adipose tissue, respectively.
