The Results of Survey. During the acclimatization process fatten features of C and D lines pigs offspring are changing to the right side. But differences are not statistically trusted. During the acclimatization process fleshy features of C and D lines pigs’ offspring practically did not change. Trusted difference in D line estimated only to carcass side length (cm), which declined 3.9 cm (p<0.001), or in C line to carcass side length (p<0.005), which shorten pro rata 5.2 cm and 3.63 cm comparing with imported pigs offspring results. Trusted differences are not estimated to the remainder rates of fleshy features. That fleshy features did not change during the acclimatization process is seen from phenotipical estimation results. Fat thickness of C line pigs pedigree get – at 1 point rise 1.84 mm (p<0.005), or fat thickness of D line pedigree get – at 1 point even decrease 0.57 mm (p<0.005), comparing with imported pedigree get. During acclimatization process reproductive features C and D line sow practically did not change, only milkyness and percentage of piglets preservation from generation to generations improved. C line sow milkyness increased 10.68 kg (p<0.005), or D line sow 13.01 kg (p<0.001). Percentage of piglets preservation increased 7 % (p<0.025) in C line and 5.69 % (p<0.050) in D line. During acclimatization process time from piglet weaning till the first insemination is shorten 1.02 and 2.14 day (p<0.025) pro rata in C line F1 and F2 generations. But this time... [to full text]
