The article describes the research results on the complex enzyme and antibacterial drugs use in feed for the Hubbard cross broiler chickens. A studies review is presented, which showed that ergotropic preparations complex use when growing broiler chickens is poultry increasing the meat productivity effective method, as per basic zootechnical indicators. As a studying result an ergotropics complex combined use effectiveness in growing poultry, a significant decrease in a highly toxic elements number concentration in the broiler chickens carcasses and organs has been established, which is very important today. The preparation complex influence on the Hubbard cross broiler chickens meat chemical composition, physicochemical and tasting parameters was traced. Our research has proved the ergotropic drugs use effectiveness in broiler chickens, which is one of the increasing poultry meat productivity effective methods and the quality products necessary to provide the population needs with high nutritional and biological products values.
The paper presents the experimental results using organic acid complexes BiSAlTek, Ecacid and NeoTerm in the diet of broiler chickens of the Cobb 500 cross. The study was carried out in the conditions of the scientific poultry factory of Belgorod State University named after V.Ya. Gorin. There were 4 groups of 100 heads each: I-control, II, III and IV-experimental. As the main diet the chickens of all groups received mixed feed corresponding to the growing periods. In addition to the main diet, the chickens of groups II, III and IV in the periods from 1 to 10 days and from 34 to 38 days of life were given BiSAlTek, Ecacid and NeoTerm acidifiers at the rate of 2.5, 0.5 and 1.5 l/t of water, respectively. The use of additives contributed to a significant, relative to the control, increase in the body weight of chickens of groups II, III and IV by 7.7%; 6.8% and 8.6%, respectively, against the feed cost reduction per 1 kg of the body weight by 8.3%; 7.7% and 9.5%.
Relevance In recent years, the negative role of some pharmaceuticals effect on the liver of an agricultural bird which hepatotoxicity sharply increases in theprocess of biotransformation in the connection with the formation of active metabolites was revealed. Poisoning with xenobiotics and hormone and protein metabolites accumulating in an organism causes intoxication and promotes increase in intensity of peroxide lipid oxidation. Therefore, biooxidantsuse which include fat-and water-soluble vitamins is necessary. Considering this, together with the staff of CJSC Petrokhim we developed a new complex drug which contained carotene, bioflavonoid complex of a larch, and fat-soluble vitamins. The drug was called Karoflavin. The purpose of the work was to study the possible use of karoflavin inbroilers with hepatosis. Results of the study The obtained resultsshowed highgrowth stimulating activity and biological availability of karoflavin, and its hepatoprotective properties. After karoflavin use bird average daily bodyweight increased by 9.5 and 10.3%, while forage use decreased by 1.1 and 1.6%, calcium serum blood level increased by 35.0 and 35.9%, vitamin A increased by 20.3 and 25.6%, aspartateaminotransferase activity decreased by 20.3 and 21ю1%, alanineaminotransferases-by 20.3 and 22.9%, glucose level decreased by 26.1 and 25.6%.
The article considers changes in biochemical blood parameters depending on the degree of adaptation process manifesting on the plantar surface of hind limbs of different sex rabbits and physiological state under cage husbandry technology. Groups of stud bucks (1st series), pregnant and lactating does (2nd and 3rd series of experiments) were formed according to the stages of structural changes depending on the stress of physiological regulatory processes of adaptation (the systematics proposed by R.M. Baevsky). The authors studied the following factors in serum: total protein, protein fractions (albumin, α-, β-, γ-globulin), creatinine, total bilirubin, urea, uric acid, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, glucose triacylglycerol and cholesterol. At the stressed stage of regulatory systems the group of bucks showed a reduction of total bilirubin on the background of decrease of ALT, AST and alkaline phosphatase, which can testify to activation of liver function at this stage, and increase in bilirubin, ALT, AST with a simultaneous decrease in alkaline phosphatase, noted at the overstress stage of physiological adaptation regulatory processes, can testify to decrease in the functional activity of hepatocytes.Pregnant rabbits have the most pronounced compensatory reactions in the third stage of the adaptation process: the increase in absolute and relative γ-globulin values indicates the activation of immune factors. An increase in creatinine and urea levels during the gestation period, against a background of developing adaptive changes on the plantar surface of the feet, indicates a decrease in the filtration capacity of the renal tubules.Lactating animals experience an increased physiological load on the liver, which is expressed by an increase in triacylglycerols throughout the adaptation.
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.
