Abstract

Records from 99,384 crossbred pigs from Duroc sires and Large White × Landrace dams were used to estimate genetic parameters for survival traits at different stages of the fattening period, and their relations with final weight. Traits analyzed were preweaning mortality (PWM), culling between...

Abstract

Genetic parameters for birth weight (BWT), preweaning mortality (PWM), and HCW were estimated for a crossbred pig population to determine if BWT could be used as an early predictor for later performances. Sire genetic effects for those traits were estimated to determine if early selection of...

Abstract

Data on 867 purebred and crossbred Duroc, Landrace and Large White (LW) litters were analysed. Birth weight averaged 1.42±0.02 kg, litter weight at weaning (at 27.94±0.63 days of age) 34.27±1.28 kg and piglet weaning weight 4.59±0.06 kg. Breed of dam had a significant effect on all the above traits ...

Abstract

Duroc, Yorkshire and Duroc × Yorkshire pigs (1328 litters in 7 generations) were typed for 11 blood groups systems. Segregation ratios for blood group genotypes were not generally significantly different from expected ratios in either sex; for the H system, however, the ratio of...

Abstract

The project was set up to investigate the best types of crossbred for local conditions, the heritability of performance traits, and nutritional requirements. The intention is to use the results in the development of a new breed for Thailand. In April 1965 there were 273 pigs of 11 types in the...
