The results of the investigation have been presented in the paper for broiler meat veterinary and sanitary traits using rapeseed meal in feeds. Rapeseed meal contains easily assimilable fiber, residual amounts of non-saturated fatty acids, plant protein and some other biologically valuable nutritional matters. It has well pronounced energetic ability for animals and poultry. Rapeseed meal using in feeds influence positively on broiler body and on meat production. Feed consumption, and body weight gain, and carcasses yield increase, chicken culling and forced slaughter decrease. Fat and protein content increase in broiler meat with rapeseed meal in feeds. Such meat has higher biological value and is in demand among the population.
Changes have been presented in broiler meat when carcasses stored frozen during to deadline. Muscle samples have been studied of broiler frozen carcasses that have been stored during 10 months in freezer with minus 18°C temperature and relative moisture 85–90%. These samples have been investigated in 2…4…6…8…10 months of storage. Sensory evaluation and meat laboratory analysis have been carried out to determine deviation for every two months in sensory traits and chemical composition, physical-and-chemical properties, microbiologic status and meat biological value traits. Changes have been established to take place in broiler meat stored frozen that influence on poultry meat raw material marketable condition and technologic and consumer quality. The most pronounced meat changes take place in the initial and final of frozen carcasses storage. Significant deviations have been detected in frozen meat after long-term storage in sensory and physical-and-chemical properties more often. Microbial contamination lowered in frozen meat stored at minus 18°C temperature but after 8 to 10 months bacterial insemination increased. Relative biologic value (RBV) and protein quality (PQ) traits lowered during the whole carcasses storage period. Some proposals for reduction of frozen carcasses storage period have been developed at the base of data received.
The article presents the rationale for the veterinary and sanitary assessment of animal slaughter products in diseases of the endocrine system and a decrease in the activity of immunity factors. The frequency of spread of immune deficiency in fattening animals and the relationship of immune reactivity with changes in the function of the glands of the endocrine system are described. Deviations were determined in the quality indicators of animal meat in diseases of the endocrine system and immune deficiency. Proposed the most rational and safe use of meat in the detection of diseases of the endocrine system and depressive state of immunity in slaughter animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
