Growth and reproductive performance of female pigs (Landrace x Yorkshire) and (Yorkshire x Landrace) raised at Indovina Thai Binh Company

Abstract

The objective of this research is to evaluate the growth rate of (Landrace x Yorkshire) and (Yorkshire x Landrace) gilts and the reproductive performance of  sows mated with Duroc boars at Indovina Thai Binh Company. The indicators of growth rate and physiology were observed on 30 (Landrace x Yorkshire) gilts and 30 (Yorkshire x Landrace) gilts. Reproductive performance was evaluated in the first litter of 60 (Landrace x Yorkshire) and (Yorkshire x Landrace) sows. Results obtained showed that: the ADG of (Landrace x Yorkshire) and (Yorkshire x Landrace) gilfs  in the period from 70 to 160 days was 758.16 and 772.85 g/pig/day, and the back fat thickness at the end of the experiment was 16.99 and 17.20 mm, respectively. The first oestrus age of (Landrace x Yorkshire) and (Yorkshire x Landrace) sows was 169.40 and 170.17 days; the age of first mating was 211.40 and 212.83 days; the age of birth giving was 339.47 and 340.25 days, respectively. The number of piglets born alive of (Landrace x Yorkshire) and (Yorkshire x Landrace) sows mated with Duroc boars was 11.12 and 11.25; the number of piglets at weaning at 22 days old was 10.92 and 11.08; the weaning weight/litter was 59.15 and 66.49 kg, respectively. (Landrace x Yorkshire) and (Yorkshire x Landrace) sows were capable of properly producing in industrial breeding conditions.
