Evaluation of the slaughter products quality of broiler chickens cross Ross-308 grown by non waste technology

Waste reclamation and disposal is an essential social duty that aims at saving both public health and the environment from preventing contamination. Meeting certain standards is necessary when dealing with poultry waste processing as their quality can affect the commodity and sanitary characteristics of poultry slaughter products in various degree when included into their diet. The aim of the work was to study the effect of feed additives administered in the form of meat and bone meal in doses 3; 6; 10% and broth in the amount of 10% to the general economic diet for veterinary and sanitary indicators of the products of slaughter of broiler chickens of ROSS-308 cross, grown in the conditions of the Orel branch of the Livensky district "Prodmeat". To conduct the experiment, four experimental groups of broiler chickens were formed at the age of 20 days old. The first control group was fed with compound feed while the remaining three experimental groups were also fed with compound feed as their primary diet. The second group received an additional 3% of meat and bone meal in their diet, the third group received 6%, and the fourth group received 10%. All three experimental groups had broth included into their diet, with a proportion of 10%. The use of the processed poultry waste was stopped three days prior to the 40-day slaughter of the chickens. During the growing period, the live weight of chickens in each group was determined at 25; 30; 35; 40 days old and a control slaughter was carried out at 30; 35; 40 days old in the slaughterhouse of the enterprise. As a result of the work carried out, it was found that the introduction of 3% meat and bone into the diet of chickens flour and 10% broth does not have a negative effect on organoleptic, physico-chemical parameters, does not cause pathoanatomic changes and bacteriological contamination of slaughter products.
