The performance and safety of the Hy-Plus hybrid rabbits (second-generation mixtures) when feeding different doses of the F1 acidifier were investigated.

The effectiveness of the acidifier "F1" is due to the synergistic combination of the properties of organic acids. The drug helps to reduce the pH and buffer capacity in water, as well as in the digestive tract of animals and birds.

Due to this action, the drug inhibits the growth and development of pathogenic bacteria (E. coli, Salmonella spp., Campylobacter spp., Pseudomonas spp., Etc.), while reducing the negative impact of pathogenic microflora on the body.

The live weight of the rabbits at the age of 40 and 149 and 194 g, respectively, was higher in the experimental groups compared to the control group. Moreover, those rabbits receiving the dosage of oxidant twice as much showed the best results of weight gain. This trend persisted in all the studied periods. Thus, the rabbits of the second experimental group increased the control groupbyliveweightat50daysofageby297g,at60days-by300g,at70days-by303g,at80 days - by 309 g, in 90 day - by 310 g. The rabbits of the first experimental group also exaggerated the rabbits of the control group, but the difference was much smaller - 172, 183, 211 and 220 g, respectively, of the studied age.

Therefore, the acidification of the acid has proved to be effective. The rabbits have increased their growth and the second generation hybrids are not inferior to the growth energy of the first generation hybrids.

The smallest percentage of conservation is present in rabbits of the control group in the 30-60 days age period (post-hatching period). Oxidant binge reduced rabbit mortality after hatching and the percentage of preservation increased significantly in experimental groups I and II by 15.7 and 21.6%, respectively (p≤0.001).

From 61 to 90 days of life, the conservation of rabbits in the control group increased by 25.7%, due to the completion of the formation of the gastrointestinal tract in young animals and the accumulation of a sufficient amount of positive microflora. In the rabbits of the experimental groups, the conservation is greater and probably differs with the control by 4.5 and 7.1%.

The results of studies have shown that the highest productivity is inherent in rabbits when introduced into the water acidifier at a dosage of 1 ml per 1 liter.
