This paper studies the chemical composition of the drone brood homogenate produced in the Primorsky Territory in comparison with the regulatory requirements and the results obtained in other regions. The composition of the homogenate was determined in the laboratory of the Pacific Institute of Bioorganic Chemistry, Vladivostok. The analysis showed that the chemical composition varies significantly for most indicators.
Meat herd horse breeding is one of the most promising projects in the industry, especially in peasant (farming) households. Meat herd horse breeding is one of the most promising areas in the industry, especially in peasant (farm) households. The number of meat herd horses is 438.2 thousand heads, incl. in agricultural organizations 161.2 thousand heads (36.8%), in peasant farms and individual entrepreneurs - 277 thousand heads (63.2%). In the conditions of the Primorsky Territory, horse breeding is not the main branch of animal husbandry, nevertheless, there are enough territories here where horse breeding could develop successfully. Breeds such as the Vladimir and Soviet heavy draft do not require much human participation, and they themselves get their own food. At the same time, the main method of keeping and breeding these breeds is herd. The assessment of meat productivity of crossbred young horses with stallions of Sovetskaya and Vladimirskaya heavy draft breeds was carried out. The use of stallions of the Sovetskaya heavy draft breed in horse breeding allowed increasing the slaughter yield by 3.6% and improve the morphological composition of the carcass in comparison with the Vladimirskaya heavy draft breed.
High contamination of incubation eggs of waterfowl and, as a consequence, penetration of microorganisms through the shell leads to embryonic mortality, poults weakness, high mortality in the first day of life, so it is important to sanitize eggs immediately after their collection. This article presents the results of using 1.6% hydrogen peroxide solution as a disinfectant for treating incubation duck eggs. The results of microbiological research of washes from the surface of incubation duck eggs, setter air, otoscopy, hatchability and safety of day-old growing are also reflected. During the study, it was found that pre-hatching treatment of duck eggs with 1.6% hydrogen peroxide solution reduced the degree of contamination on the shell surface, hatchability of eggs in the experimental group was higher by 3.1% than in the control group, safety - by 3.6%, respectively.
Homogenate is a source of a huge amount of biologically active substances. However, it is produced in a small number of apiaries, since the cultivation of drone brood negatively affects honey productivity. This paper aimed to study the influence of rearing drone larvae on the power and honey productivity of bee colonies since these issues are not widely addressed in scientific literature. Three groups (control, experimental 1, and experimental 2) of 10 bee colonies were formed by the method of pairs-analogs. One brood frame was placed in the bee colonies of the first experimental group, and two frames were placed in the colonies of the second experimental group. The brood frames were placed on June 12, the clipping was done on June 30, and the honey was collected on July 12. The power of colonies was taken into account after wintering (in March) and at the end of the pre-wintering season (in November). As a result of the research, it was revealed that the homogenate of drone brood can be obtained in apiaries of the Primorsky Krai. It was proved that when adding one brood frame to obtain a homogenate, the main production of the apiary - honey, does not decrease, and a negative effect on honey productivity was observed when adding the second brood frame.
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.
