We studied the influence of feeding Protecto-active probiotic in complex with Matseraza enzyme on productivity of young pigs.

Piglets of the control group were fed with main diet. Piglets of the 2nd experimental group received the diet probiotic in the amount of 1.5 g per 10 kg of live weight and piglets of the 3rd, the 4th and the 5th experimental groups were added with enzyme Matseraza to thir feed in the amount of 0.5 kg per ton of feed. Enzyme Matseraza was fed to pigs of the 5th experimental group on the 1st day of the experiment, to pigs of the 4th group on the 31st day of the experiment, to pigs of the 3rd experimental group on the 61th day of the experiment.

The 5th experimental group diet included Protecto-active and Matseraza from the first day of the main period of the experiment, after the first month (age 46–75 days) they dominated over their peers in the control group on average daily gain by
10.5 % (p<0.01), while pigs of the 2nd, the 3rd and the 4th experimental groups – by 3.1 %; 3.1 % and 1.3 %.

By the second month of the experiment (76–105 days) the average daily gain of the 5th experimental group pigs were
430 g and it is more than in the control group by 17.3 % (p<0.05). At the same time, the average daily gain of the pigs of the 2nd and 3rd experimental groups increased by 7.3 and 6.4 %, and 4th experimental group – by 10.9 %.

By the 3rd month of the main period of experiment (age 106–135 days) the highest average daily gain was observed in piglets of the 4th experimental group – 610 g and it is more when compared with the control one by 15.8 % (p<0.05). At the same time in piglets of the 5th, of the 3rd and the 2nd experimental groups increased average daily gain, respectively, by 13.9 %; 13.9 % (p<0.05) and 8.2 %.

By the fourth month of the experiment (age 136–165 days) the highest average daily gain was in pigs of the 3rd experimental group. This animals group diet was added with Protecto-active from the first day, and Matseraza – from the 61th day of main period of the experiment. Average daily gain of pigs was 710 g and it is more when compared with piglets in the control group by 17 % (p <0.01). At the same time the pigs of the 4th, the 5th and the 2nd experimental groups dominated over the control one by this indicator, respectively by 14.8 % (p<0.01); 13.7 % (p<0.05) and 6.6 %.

During the fifth month of main period of the experiment (age 166–195 days) the highest average daily gain was in pigs of the 3rd experimental group – 853 g and it is more than in control animals by 16.9 % (p <0.01). Growth rate of the 5th and the 2nd pig groups was higher than the control by 8.7 % and 5 % respectively. Pigs of the 4th experimental group had average daily gain at the level of 823 g and they were above the average daily gain of animals of control group by 12.8 % (p<0.01).

During the 6th final month of main period of the experiment (age 196–225 days) the highest average daily gain had the pigs of the 3rd experimental group. These animals dominated over control by 13.7 % (p<0.05). At the same time, pigs of the 2nd, the 4th and of the 5th experimental groups had these indicators higher as compared to the control group analogues, respectively by 4.4 %; 8.8 % and 3.1 %.

It was established, that during the whole period of experiment the best average daily gain was in pigs of the 3rd experimental group. This group animals diet was added with Protecto-active from the first day and for 120 days, and Matseraza – from 61th day of the main period and during 120 days. Average daily gain of the 3rd experimental group pigs was 599 g and it was above average daily gain in the control group by 13.7 % (p<0.001). In animals of the 2nd, the 4th and the 5th experimental groups the average daily gain was 558 g, 590 g and 582 g, respectively. It is higher than the gain of pigs in the control group by 5.9 %; 11.9 % (p<0.01) and by 10.3 % (p<0.01).
