Evaluation of the quality of meat products when using the butaphosphan-containing pharmacological agent SM-complex

Abstract

Оne of the ways to increase the productivity of chickens is to use different groups of pharmacological agents as growth stimulants. The most commonly used products include vitamins, amino acids, feed antibiotics, probiotics, adsorbents, and organic acids. The work carried out studies proving the ability of the developed butaphosphane-containing pharmacological agent CM-complex to influence the growth dynamics of broiler chickens and assess this effect on the quality of meat products. With standard 39-day and long-term 56-day industrial fattening of broiler chickens, the effect of the SM-complex increases meat productivity by 12.8% and 14.5%, respectively. Depending on the sex of the chickens, at 39 days of age, the effect of the SM-complex is manifested by an increase in body weight in hens by 19.3%, in cockerels by 12.3%; at the age of 56 days by 12.9% and 18.5%, respectively, while the lean body mass index increases by 13.8%, which indicates the formation of a larger and stronger physique in broilers. The use of the CM-complex makes it possible to increase the slaughter yield by 4.7% and the output of the pectoral muscles by an average of 14.9%: in roosters by 6.2%, in hens by 27.2%. The amount of dry matter in white meat of the experimental group increases by 3.9% when slaughtered at 39 days and by 4.3% at the age of 56 days. During 56-day fattening, there is an accumulation of fatty tissue between muscle fibers and in the subcutaneous tissue, which has a positive effect on the nutritional value and culinary properties of the resulting meat products. We recommend such long-term fattening for the production of meat “organic products” of poultry farming.
