Abstract
Occasional use of the probiotics Levisel SB Plus and Tsellobacterin – T in a dose 0.50 kg/t of the mixed fodder in a diet of the laying hens at the age 21-26, 34-39 и 45-48 weeks has increased metabolic processes in the body of a bird and productivity of the laying hens in a group with Levisel SB Plus by 10.6 %, with a dash Tsellobacterin – T – by 16.1 %, but it did not affect the weight of the egg during all periods of the productive cycle. The egg incubation results showed that probiotice Levisel SB Plus increased egg hatability by 4.1%, Tsellobacterin-T by 6.2%, their fertilization by 2.1 and 4.2%, the withdrawal of young chickens by 3.5% and 5.1%. The addition of probiotics did not change the hatchability of eggs (93.22 and 93.17%) in these groups, but reduced the amount of unfertilized eggs by 1.8 and 10.3%. There was a higher content of carotenoids and vitamin A in the eggs of the laying hens and in the body of daily chickens. Using the probiotics in the diet of laying hens of the parent herd has reduced the cost of feeding for 10 eggs by 8.2-8.5% , with a dash of Levisel SB Plus by 15,0-15,4%, with a dash of Tsellobacterin – T to the weight of the egg by 1,8-9,7% and 15.3-15.5% respectively. At the same time, the payment of food products increased in the group using Levisel SB Plus by 10.3-10.7%, with Tsellobacterine - T by 20.9- 21.7%, the profitability of production increased by 13.1 and 22.3%.
Highlights
Probiotic fodder additives used in the diets of agricultural animals and birds instead of antibiotics, have a polyfunctional effect on the body of the bird
Inclusion of the sinbiotics "ProStor" in the amount of 0.50 kg / t of mixed fodder in the diet of the growing birds of the meat direction, did not give reliable differences in living weight at the time of the transfer of the bird to the parent herd, but the safety of the head of the experimental group was higher by 2.6%, which amounted to a profit of 2.7%
The livestock of the I control and experimental groups were formed by the repair young of the cross ‘ISAHubbarf - 15’, which during the growing period at the age of the first 6 weeks received probiotics Levisel SB Plus (II experimental group) and Tsellobacterin-T (III experimental group) in a dose of 0.50 kg t-1 of mixed fodder
Summary
Probiotic fodder additives used in the diets of agricultural animals and birds instead of antibiotics, have a polyfunctional effect on the body of the bird. Probiotics were used in the treatment and prevention of gastrointestinal diseases of agricultural animals, in the following as a biologically active additives, normalizing bacterial composition of the intestine [3, 8], increasing variability and nutrient use of the diet, safety of the livestock [2], immune status of an organism [1]. Inclusion of the sinbiotics "ProStor" in the amount of 0.50 kg / t of mixed fodder in the diet of the growing birds of the meat direction, did not give reliable differences in living weight at the time of the transfer of the bird to the parent herd, but the safety of the head of the experimental group was higher by 2.6%, which amounted to a profit of 2.7%. Egorov and others [4] noted that spore forms of probiotics reduce lipolitical, but increase activity of duodenal himus
