In vitro produced embryos are not marketed frozen due to special conditions that render them unable to survive after freezing. Technology used for embryos in co-cultures will be improved and applied to a simple, semi-defined medium.
The aim is to replace harmful feed additives (antibiotics, zinc oxide) by natural bioactive substances that stimulate the growth and health of production animals and do not have a negative effect on the environment.
A new synthetic chinese-european line will be selected and developed. A programme of research on molecular genetics will make it possible to identify different genes which can be candidates for the characters of reproduction and meat quality.
Development of a non-traumatic and non-stress technique to artificially inseminate ewe.
Modifying the fatty acid composition of pork through animal nutrition to achieve meat with more polyunsaturated fatty acids and favourable ratio n-3 to n-6 fatty acids to benefit consumers' health.
To develop an efficient technique to inseminate nuliparous and multiparous sows. We propose the use of an easy to use transcervical catheter, a reduced insemination dose and a single insemination per estrus.
Transcervical insemination (tc-ai) in swine is successful with the easy-use catheter magaplus. To complete the new tc-ai system we will design: 1. A specific packing system and/or an applicator for sperm doses. 2. A device to fix the catheter during the slowest inseminations.
Homogeneous and quality results in cross-breeding pigs with the goals of investigating the homogeneity and quality of herdability genetic characteristics in three cross-breeding pigs.
Improvement of fertility and prolificness in swine reproduction. Evaluation of genetic factors and animal welfare that affect the semen quality of males in artificial insemination centres and embryo mortality in sow farms.
To objectively evaluate different diets and production systems as well as their effects on performance, carcase results and meat characteristics, in order to ensure that upb breeds meet high added-value market requirements.
