The work was carried out in 2022 on Phoenix quails. From the age of one day, in addition to the main diet, the birds of the experimental group daily received a suspension culture of <i>Enterococcus faecium</i> ICIS 96 with a cell concentration of 1 × 10⁹ in 1 mL at the rate of 0.1 mL per 1 kg of live weight. To achieve this goal, a scientific and economic experiment was carried out. At the first stage, the influence of the <i>Enterococcus faecium</i> ICIS 96 strain on the growth, development, and meat productivity of quails up to 42 days was determined, and at the second stage on the egg productivity of quails. The live weight of quail in the experimental group was higher than in the control group at all age periods: on the 28th day by 19.4 g, or 15.02%, on the 42nd day by 23.8 g, or 9.0%. The weight of gutted quail carcasses, which received in addition to the main diet a suspension of <i>Enterococcus faecium</i> ICIS 96 culture, was greater than in the control by 25.42%, half-gutted by 25.33%, and slaughter yield by 8.9%. The highest egg production during the productive period (30 weeks) was observed in quails of the experimental group: the gross collection of eggs was 5365 pcs, which was 701 pcs more than in the control group. At the same time, the thickness of their shell was 8.6% higher. As a result, revenue from the sale of eggs was higher by 4429.2 rubles, and the level of profitability by 4.5%.</p>","PeriodicalId":21531,"journal":{"name":"Russian Agricultural Sciences","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140887409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the efficiency of obtaining cloned offspring remains relatively low. A number of studies on small livestock, including sheep, have shown that the use of laparoscopy, compared with the traditional method of embryo transfer via laparotomy, is associated with less trauma and allows an increase in the pregnancy rate of a recipient. Such studies have not previously been conducted with cloned embryos. The purpose of the study is to compare laparotomic and laparoscopic methods of transplanting cloned embryos in sheep. The work was carried out on Romanov breed sheep (<i>n</i> = 12 and 13, respectively). We preliminarily assessed the effectiveness of the ultrasound protocol used to determine pregnancy in sheep at different stages of the gestational period. Transplantation of 2-day-old cloned embryos was carried out on the 2nd day after heat detection. Diagnosis of pregnancy after embryo transfer was carried out using ultrasound on days 35–41 after transplantation. Accuracy of a positive prognosis (confirmation of pregnancy) at all periods of ultrasound diagnostics according to the applied protocol by the 28th–29th, 35th–36th, 42nd‒43rd, 56th–58th, 71st, 85th and 98th day was 100%. The use of the laparoscopic method for transferring cloned embryos was not associated with mortality during surgery, while with surgical transfer it was 8.3%. The use of the laparoscopic method made it possible to reduce the duration of the operating procedure by 2.9 times on average from 44.1 ± 13.3 to 15.4 ± 4.3 minutes (<i>p</i> &lt; 0.01). The percentage of pregnancy achieved using the laparoscopic method was comparable to the results of surgical transfer of cloned embryos and was 30.8 ± 12.8% versus 36.4 ± 14.5%. In general, the use of the laparoscopic method for transplanting cloned sheep embryos is characterized by lower trauma and a significant reduction in the period of the surgical procedure without loss of effectiveness.</p>","PeriodicalId":21531,"journal":{"name":"Russian Agricultural Sciences","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140887413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of biotesting of samples at 20°C and humidity of 60% of field capacity showed that the half-life of herbicides (DT50) comprised 40 ± 3 days after the incubation start, and detoxification to the level of 70–80% occurred 200–240 days after the introduction of herbicides into the sod-podzolic.

Over the recent decade, selective breeding with molecular markers has provided the opportunity to improve the sheep muscular system and the carcass weight and yield with decreasing the fat accumulation. Recognition of genes affecting the characteristics of farm animal products has allowed the researchers to identify single nucleotide polymorphisms (SNPs) associated with phenotypic traits improving the productive performance of livestock. Alleles of genes calpastatin (<i>CAST</i>) and somatropin, the synthetic form of growth hormone (<i>GH</i>) can represent the potential markers for sheep meat productivity. The objective of the survey is to study polymorphic variants of the <i>CAST</i> and <i>GH</i> genes in meat and wool sheep of the genotype of cross 1/2 Poll Dorset ×1/2 North-Caucasian meat-and-wool breed, reared in the Stavropol krai and their relationships with the traits important in meat production. Sheep genotyping for the somatotropin and calpastatin genes was performed with the method of PCR restriction fragment length polymorphism (PCR-RFLP). The evaluated genes were polymorphic. Three genotypes (<i>AA</i>, <i>AB</i>, and <i>BB</i>) of gene <i>GH</i> and two genotypes (<i>MM</i> and <i>MN</i>) of gene <i>CAST</i> have been identified. Genotypes <i>AB</i> and <i>MM</i> were characterised by the highest frequency of occurrence (42.8 and 87.9%, respectively). The highest values for meat production were recorded in the ewes with the <i>AB</i>, <i>BB</i>, and <i>MN</i> genotypes. The slaughter weight of specimens with genotype <i>MN</i> of the <i>CAST</i> gene was greater than that in the sheep with homozygous genotype (<i>MM</i>) by 5.9% and in the animals with genotypes <i>AB</i> and <i>BB</i> of gene <i>GH</i>, compared to the ewes with genotype <i>AA</i>, by 6.8 and 7.5%, respectively.

In 2015–2020, 14 varieties were studied in the conditions of the Cis-Urals and 17 varieties were studied in the Trans-Urals. The experiments were carried out: in the Cis-Ural region on ordinary chernozem with a content of 2.9–5.6 mg/100 g of nitrate nitrogen in the soil layer of 0–30 cm (per 100 g), 2.3–2.8 and 26.7–38.4 mg/100 g of mobile phosphorus and potassium (according to Machigin); in the Trans-Urals on southern chernozem with a 4.3–5.8 mg/100 g of nitrate nitrogen, 0.8–1.9 and 25…48 mg/100 g of mobile phosphorus and potassium (according to Machigin).

The yield of the studied varieties in favorable years reached 3.94 t/ha in the Cis-Ural region and 3.05 t/ha in the Trans-Ural region.
