PRODUCTIVE ACIDFUL ACTION OF FEED ASID STAG S BF ON GROWTH INTENSITY AND FUNCTIONAL STATE THE ORGANISM OF THE YOUNG KILLS FOR THE INTENSIVE BREEDING OF MEAT

Abstract

The studies were conducted at the Carpathian State Agricultural Research Station. The farm uses developed technology of intensive production of rabbit. The genotype of farm-bred rabbits is three breeds of white giant, chinchilla and flinders (NTSH).

For the experiment, by the method of pair-analogues, 5 groups of young rabbits of 15 heads in each were formed. The first control group was fed feed without acidification, 2, 3, 4 and 5 experimental groups with a content of 0.1; 0.3; 0.5; 0.7% of acidifying feed Asid Stag S BF.

The maximum live weight of one head at 90 days of age was in the 4th experimental group, amounted to 2,967kg where the acidifier of feed ASID STAG S BF in the amount of 0.5% was used, while, when using this acidifier in the diet of feeding young rabbits 2nd of the group (0.1%) was - 2,877 kg, of the 3rd group (0,3%) - 2,89 kg, and of the 5th (0,7%) - 2,9 kg.

The average daily increments for the period of 40-90 days were higher in the fourth experimental group (0.5%) - 42.1 g, slightly lower when using the acidifier ACID STAG S BF in the diets of pre-study groups of rabbits: 2nd (0.1 %) - 40.2 g; 3rd (0.3%) - 40.6g; and 5th (0.7%) - 40.9g.

Measured lifetime indicator - the width of the waist at 3 months of age in the rabbits of these groups was 5.9 cm, in the 2 and 5 groups, when introduced into the diet of

experimental rabbits acidifier feed ASID STAG S BF in the amount of 1 kg and

respectively 7 kg per ton ready feed this figure is 5.8 cm.
Feed costs in 1-, 2-, 3-, and 5 groups were 3.55; 3.48; 3.4 kg and 3.41 kg of

finished feed per 1 kg of increase, while in group 4, they were somewhat more effective and found at 3.32 kg.

The best indices of fattening productivity with the introduction of 5 kg of acidifier feed ASID STAG S BF per tonne of prepared feed (experimental group 4) were obtained due to the efficiency of physiological influence of low molecular weight organic acids on the digestion process of mono-gastric, herbivorous rodents, which was manifested in the better feed. At the same time the fattening indices of the 4 experimental groups increased to 1 rabbits: control weight at 90 days of age, 190 g; average daily gains of 3.9 g; width across 0.2 cm; improved feed conversion by 230g

Reduction of the cost of feed per 1 g of increase to 1 control group (2485 UAH), occurred to 4 groups: 2 experimental 2464 UAH; 3 experimental 2461грн, 4 experimental 2457грн. The cost of feed in the cost structure of the 5 experimental group was the highest - 2578UAH. Such dynamics had an impact on net profit and profitability.
