|Články v odborných časopisech
The objective of this study was to estimate the effect of piglet birth weight on future growth intensity of Prestice Black-Pied (PC) pigs and hybrid (H) pigs (LW x L x LW sire line). The pigs were divided in three groups according the birth weight (less than 1 kg, from 1.1 to 1.5 kg and more than 1.51 kg). The experiment was terminated when the pigs reached a slaughter weight, at 181 days of age and average live weight 116.24 kg in H pigs and 197 days of age and 98.65 kg in PC pigs. The positive effect of birth weight of piglets on their growth intensity was found in our study. There were found statistically significant differences in live weight at weaning (P ≤ 0.001) and slaughter weight (P ≤ 0.001) in PC and H pigs.
