Improving physiological status and meat quality of rabbits by the application of probiotic complex “Sporotermin” in compound feeds

Abstract

The productive qualities of rabbits and meat quality depend on proper feeding. But due to the intensive technologies introduction in rabbit breeding, the animals stress sensitivity increases, their physiological status decreases, causing pathological conditions. Probiotic additives enhancing the animals immune status and resistance and having a positive effect on their productivity are introduced into the production cycle to increase the safety of young animals, as well as to restore and maintain the microflora of the digestive tract. This approach allows to reduce the consequences of the uncontrolled antibiotics use , which contribute to increased variability of pathogenic microflora and their accumulation in the breeding object tissues. The effectiveness of the Sporothermin probiotic complex application to increase the physiological status and efficiency of rearing young rabbits was studied in the work. The studies were carried out on a cross-breeding stock of rabbits obtained by industrial crossing of the parental forms of the breeds Soviet chinchilla and New Zealand red at the age of 60 days in the industrial complex LLC Lipetsk rabbit. The effect of the probiotic complex on the immune and clinical status was studied in 60 rabbits, divided into control and experimental groups using the pair-analogue method. Rabbits of the control group received PK-90 compound feed, the experimental group rabbits were fed with PK-90 compound feed with the introduction of the Sporotermin probiotic complex in a dosage of 0.6 and 1.0 g / kg of compound feed. The application of a probiotic complex in an optimally selected dosage of 1.0 g / kg of compound feed had a positive effect on the growth rate, physiological status of the organism and the quality indicators of rabbit meat, which is the basis for its use in industry
