PRODUCTIVE QUALITIES OF PIGS AGE FROM 61 TO 90 DAYS WHEN USING POLNORATSIONNY COMPOUND FEED ACCORDING TO SSTU 4124-2002

Feeding of piglets aged from 61 to 90 days is differentiated into three age periods - from 61 to 70 days, from 71 to 80 and from 81 to 90 days. In the first age period piglets are fed with 1,0 kg of complete feed per day, in the second one – 1,4 kg and in the third age period – 1,8 kg of complete feed per day. It has been established that the use of complete feed for piglets with a live weight of 20-40 kg, according to the State Standard 4124-2002 leads to an increase in live weight of piglets aged 61 to 90 days from 18,5 to 35,5 kg at the average daily gain - 570 g and at the conversion of 2,5 kg of mixed fodders per 1 kg of piglets gain. It was concluded that obtained productivity of piglets aged from 60 to 90 days using complete feed for piglets with a live weight of 20-40 kg, according to the State Standard 4124-2002 has not met the requirements of intensive pig breeding. It has been determined that the use of complete feed for piglets with a live weight of 20-40 kg with low concentration of sodium chloride, calcium and phosphorus and improvement of piglets 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 piglets aged from 61 to 90 days.
