These periods are the most stressful, since the uterus does not receive enough necessary nutrients for the normal functioning of the body, embryonic and post-embryonic development of the offspring. In this regard, the purpose of our research was to increase the usefulness of the diet queens by carrying out additional feeding crushed barley with the inclusion of a mineral supplement developed taking into account the chemical composition of feed in Kazakhstan. To establish a nutrient deficiency in the diets of pregnant and lactating ewes, the botanical composition and the amount of food eaten were determined. pasture feed in basic farms typical of southeast Kazakhstan. Chemical compositions, nutritional value of pasture and grain crops feed installed using devices from the Swedish company FOSS: InfraXact, FIAstar 5000, KJELTEC, as well as taking into account generally accepted standards for feeding sheep of different sex and age groups. To increase the nutritional value of the diet ewes experimental groups were fed crushed barley in the amount of 0.4 kg, and animals of 2 experimental groups in its composition, also received mineral supplement \u201cAgrovit\u201d at the rate of 4 grams per head per day. In beginning of lactation about uterine 2 experimental groups peasant farms were superior by 2.45 - 2.20% by live weight over control analogues that grazed only on pasture. A similar dynamic continued to mid-lactation. Feeding pregnant and lactating ewes in the specified volume, and animals of 2 experimental groups, also mineral supplement contributed to an increase in the milk productivity of queens and the intensity of growth and development of their lambs, which is an important factor for obtaining and raising breeding young sheep.<\/jats:p>","DOI":"10.1590\/1519-6984.288520","type":"journal-article","created":{"date-parts":[[2024,12,16]],"date-time":"2024-12-16T11:45:58Z","timestamp":1734349558000},"source":"Crossref","is-referenced-by-count":0,"title":["Effect of fertilizing on the productivity of pregnant and lactating queens, growth and development of their offspring"],"prefix":"10.1590","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6634-4189","authenticated-orcid":false,"given":"T.
