Metabolic response of broiler chickens to different doses of ICIS 96 in the diet.

The competitiveness and profitability of the poultry industry in market conditions are hampered by growing problems with the safety and quality of poultry meat. The use of targeted microbial preparations can assist in resolving these problems. Numerous studies of the properties of bacteria of the genus have shown their effectiveness in the practice of poultry farming.

Damage to seeds by screw working bodies.

Seed damage caused by screw working bodies of agricultural machines reduces the seed quality and increases the total cost of crop production. This paper describes the impact interaction of a particle with screw flights when seeds are fed into the transportation zone. There are velocity dependences during the impact and reflection of seeds on the screw surface at the maximum distance of the radius from the screw rotation axis.

The effective use of adaptogens of various origins on the cattle productivity.

Background: In conditions of industrial animal husbandry, it is necessary to pay attention to the immune system, which regulates metabolic processes in the body of animals. To do this, additives with adaptive properties attract attention.

Aim: The aim is to define a way to increase productivity using adaptogens of plant and animal origin in feeding cattle.

Egg-laying capacity of parent flock geese at different stocking densities.

This article presents the results of studies aimed at establishing the optimal stocking density of purebred and hybrid geese of the parent flock, taking into account the indicators of their live weight and egg production. When conducting research, the stocking density of geese was established depending on the breed and shape. Different stocking densities of geese in groups were achieved due to their different numbers in groups: Kuban 1.

Productive qualities of geese when crossing breeds and using hepatoprotective complex.

The study was on a one-way cross between Wanxi male and Lindov female geese, and tested the effects of a hepatoprotective compound on growth and other traits in the parental and one-way cross involving male and female progeny. The hybrids obtained from crossing had high viability and productivity; their level was also positively affected by giving a hepatoprotective complex. Female parents were the Lindov breed's geese, and male parents were 120 geese of the Chinese Wanxi breed.

Soil fertility analysis in the Republic of Bashkortostan.

The manuscript presents the materials of soil fertility analysis of agricultural lands in the north-eastern forest-steppe of the Republic of Bashkortostan in the conditions of the Salavatskiy district of the republic (Russian Federation). Agrochemical analysis of the humus accumulation, mobile phosphorus, exchangeable potassium was carried out, morphological properties were studied, the thickness of the humus horizon, granulometric composition and soil erosion were determined. During the 49-year period of agricultural land use, it was revealed some of the medium-humus soils passed into the category of high-humus, caused by the fact that the arable lands were not used for cultivating crops and they were withdrawn from circulation and sown with many-year-old grasses.

Identification of promising alfalfa varieties in conditions of the southern forest-steppe zone (Republic of Bashkortostan): a study of economic and biological characteristics.

Background: Alfalfa (Medicago sativa L.) is one of the most important forage crops, but its seed productivity varies from year to year due to weather conditions. Alfalfa is a forage crop rich in nutrients which makes it valuable.

Analysis of the interaction of seeds with a centrifugal disk working body of a chamber-type treater.

Presowing seed treatment is the first step in growing crops and obtaining a predicted high-quality yield. It plays a vital role in an integrated plant protection system. When treating seeds before sowing, it is crucial to avoid seed damage by the machine working bodies to obtain the planned harvest.

Application of ultrasound for enhancing fermentation rates in brewing technology.

Background: There is much promise in technologies which may speed up time-consuming processes such as preparing seed yeast, primary fermentation and improving beer quality in the brewing industry. This study focuses on the activating and disintegrative effect of ultrasound with a 44 kHz frequency and a 1.0 W/cm2 intensity on brewer's yeast.

The effect of an energy additive on the metabolism of cattle.

The objective of this study was to determine the effect of an energy additive on the metabolism of cattle. This article provides information on the analysis of the diet of young cattle calculated for when the animals were both indoors and outdoors. The ration was prepared for 40 heifers, divided into 4 groups consisting of 10 animals in each group.

Efficiency of high-carbohydrate fodder in the diets of Holstein cows.

Aim: This study aimed to analyze the efficiency of carbohydrate-enriched rations fed to pasture and stall-housed cows.

Materials And Methods: Forty Holstein cows were divided into four groups of 10 animals each. The experiment lasted 305 days.

Effect of hydroponic green herbage on the productive qualities of parent flock geese.

Background And Aim: Green food is the natural diet for livestock and poultry. Therefore, production of green food in sufficient quantities to meet the current demand has emerged as an urgent problem today. The use of natural laylands results in green food shortage, which, in turn, necessitates the application of various methods of artificial production of green herbage.

Effect of the bovine gene polymorphism on milk- and meat-producing ability.

Aim: This study aimed to determine the effect of thyroglobulin () gene polymorphism on milk and meat productivity in the various cattle breeds currently bred in the Republic of Bashkortostan.

Materials And Methods: The test was performed on dairy cattle of Black-and-White, Bestuzhev, and Simmental breeds, and meat cattle of Hereford and limousine breeds. The purpose of the test was to search for associations between the polymorphic alleles of the thyroglobulin () gene and economically useful traits.

Ways to reduce anti-nutritional substances in winter rye grain.

The purpose of this research was to establish the nature and extent of the influence of microwaves and extrusion on the content of anti-nutritional substances of winter rye grain. There was performed two-factor laboratory experiment with the treatment of winter rye grain by electromagnetic waves of super-high frequency (microwave) on a LG MS-2042G installation and one-factor laboratory experiment with grain treatment using a MKP-30-500 extruder. Depending on the power and duration of the microwave treatment, the content of water-soluble pentosans decreased by 0.

Phytoecdisteroids from Serratula coronata when growing ducklings.
