Productive and biological features of breeding Irish pigs of various genotypes in Western Siberia

The present work studies the productive and biological characteristics of breeding Irish pigs of different genotypes in the conditions of Western Siberia. Pure-bred selection of Large White pigs (WP) was used in the first control group and intra-breed selection of Landrace pigs (LP) was used in the...

Pure-bred selection of Large White pigs (WP) was used in the first control group and intra-breed selection of Landrace pigs (LP) was used in the second control group. The following patterns of interbreeding were used in the experimental groups: ♀WP × ♂LP (third group), ♀LP × ♂WP (fourth group). In terms of reproductive qualities, the best combination should be considered the selection of ♀WP × ♂LP, in which 8.1% (p <0.05) more piglets were obtained at 30 days, with a 10.0% (p <0.05) higher weight of the nest at 30 days and 3.6% (p <0.05) greater safety than in the first control group. The combination of breeds according to the ♀LP × ♂WP scheme contributed to an increase in the average daily 13.7% (p <0.05) gain in live weight of the resulting offspring. At the age of 4 months, piglets of the LP × WP genotype had a 10.9% (p <0.05) higher content of total protein in the blood serum than in animals of the Large White breed. The muscle tissue of Large White pigs was characterized by a 5.2% (p <0.05) higher moisture binding capacity in relation to Landrace pigs. The melting point of fatty tissue was lower in Large White pigs by 14.3% (p <0.05). The fatty tissue of LP × WP hybrids has a 10.0% higher melting point (p <0.05) in contrast to Large White pigs.Burtseva SvetlanaKhripunova LyubovYashkin AlexanderPautova LyudmilaChebakov SergeyEDP SciencesarticleMicrobiologyQR1-502PhysiologyQP1-981ZoologyQL1-991ENFRBIO Web of Conferences, Vol 37, p 00123 (2021)
