В статье представлены данные по динамике живой массы и морфологическим показателям мяса чистопородных эдильбаевских баранчиков и ярок, помесей первого поколения, полученных от скрещивания эдильбаевских маток с баранами дорпер. Среднесуточный прирост за период от рождения до 8-месячного возраста был выше по помесным животным, по баранчикам превосходство составило 6,0%, по ярочкам 10,6% соответственно. По плодовитости превосходство помесей над сверстниками составило 8,0 % и выходу деловых ягнят 10,0 %. Доля мякоти увеличивалась с возрастом и имела явные преимущественные показатели у баранчиков опытной группы (Эд×Д). В 5-ти месячном возрасте оно равнялось 11,3%, а в 8 месяцев – 12,2% (Р≤0,05). По массе соединительной и костной ткани статистических различий между группами не наблюдали.

The article discusses the technology of cultivation of one of the varieties of the sorghum species – fodder sorghum, the Ros variety. The West Kazakhstan region is located in a zone of risky agriculture and has a sharply continental climate: there is little precipitation in the summer, and the temperature is mostly high. In such climatic conditions, the need for cultivation of crops resistant to drought and lack of productive moisture increases. Such a crop is fodder sorghum. In addition to the drought resistance of sorghum, this crop is also unpretentious to soils and can grow without choosing a precursor and soil type. The Ros variety belongs to the forage sorghum and is adapted to our climatic conditions. The only condition for cultivating sorghum is mandatory pre-sowing tillage to destroy weeds and create optimal conditions for the formation of a powerful root system of the crop, reaching almost 4 meters in depth. The timing of sowing also plays an important role in the cultivation of crops. Sowing is carried out when the soil is warmed up to 12-140C, therefore, sowing was carried out on May 12-15, 2023, the sowing method is wide–row with row spacing – 45 cm. The growing season was 102 days.

The article discusses household waste management within the framework of implementing the “Green Economy” in the Republic of Kazakhstan. Improving the efficiency of household waste management is a pressing issue both for the entire Republic of Kazakhstan and the West Kazakhstan region. Currently, Kazakhstan lacks a systematic approach to separate waste collection at the “source” of generation. Therefore, a comprehensive economic analysis is being conducted across the country to develop systems for waste separation, separate disposal, recycling, and resale. Household waste recycling, especially the reuse of waste cooking oil, is an urgent problem. This study proposes the idea of producing environmentally friendly soap by reusing waste cooking oil.

The article discusses the signs of sexual reflexes associated with reproduction in he-goats, which have important biological significance in assessing reproductive traits. The simplest and most effective method during the breeding season is to determine the female's estrus by the sexual reflexes of he-goats. Thus, knowledge of the sequence of sexual reflexes in goats will allow monitoring future reproductive processes

The implementation of a waste-free technology strategy is an important step in the efficient development of the dairy processing industry. This strategy aims to increase the efficiency of production processes through waste reduction, recycling, and the introduction of environmentally friendly production methods. In the dairy processing sector, it is crucial to explore opportunities for turning by-products such as whey into valuable products, as well as the production of biofuels or biogas. Additionally, energy saving, the use of renewable energy sources, and the implementation of heat recovery systems can help reduce the ecological impact of production. Waste-free technologies require innovative solutions and scientific research, as well as significant government support and financial incentives. Through these approaches, the dairy processing industry can become an environmentally friendly, efficient, and sustainable production system.

The use of waste-free technologies in the dairy industry is an important direction for Kazakhstan from an ecological and economic point of view. These technologies allow to reduce production waste and use resources more efficiently, which reduces environmental damage and increases product quality.
