PRODUCTIVITY OF PIGS AT THE AGE FROM 91 TO 130 DAYS FEEDING WITH COMPLETE FEEDS

Feeding of pigs aged from 91 to 130 days is differentiated into four age periods - from 91 to 100 days, from 101 to 110, from 111 to 120 and from 121 to 130 days. In the first age period pigs are fed with 1.8 kg of complete feed per day, in the second one – 2.0 kg, the third – 2,2 kg and in the fourth age period – 2,4 kg of complete feed per day. It has been established that the use of complete feed for pigs with a live weight of 40-70 kg, according to the State Standard 4124-2002 leads to an increase in live weight of pigs aged 91 to 130 days from 40 to 66.5 kg at the average daily gain - 663 g and at the conversion of 3.2 kg of mixed fodders per 1 kg of pigs gain. It was concluded that obtained productivity of pigs aged from 91 to 130 days using complete feed for pigs with a live weight of 40-70 kg, according to the State Standard 4124-2002 has not met the requirements of intensive pig breeding and characterized by low economic efficiency of pork production. It has been determined that the use of complete feed for pigs with a live weight of 40-70 kg with low concentration of sodium chloride, calcium and phosphorus and improvement of pigs amino acid nutrition because of the threonine inclusion to the mixed fodder's composition must be the main direction to increase the productive qualities of pigs aged from 91 to 130 days
