The aim of the experiment was to establish the influence of different levels of energy supply of trout on its performance. For this purpose, five experimental groups were formed by the method of analogues. During the equalization period, the experimental fish consumed feed of the control group. In the main period, the level of metabolic energy in trout feed ranged from 14 to 18 MJ. As a result of the conducted researches it is established that the increase of energy content in compound feed for trout larvae and fry from 16 to 18 MJ contributes to the increase of their weight by 11.1 % (p < 0.05) and growth intensity - by 5.6-14.2 %, while the reduction of energy content to 14 MJ / kg contributes to a probable decrease (p < 0.05) in mass by 11.9%, and a decrease in growth intensity by 6.0-14.7 %. It is proved that the feed consumption per 1 kg of weight gain in trout larvae and fry, which received feed with an energy content of 18 MJ was lower by 5.1 %, and with its content of 14 MJ - 4.8 % higher compared to fish consuming feed with an energy content of 16 MJ / kg. The safety of the experimental fish throughout the experiment was close and ranged from 83.1 to 84.9 %. However, it is most economically feasible to grow trout that consume feed with a nutritional value of 16 MJ of metabolic energy, compared with a decrease or increase of this indicator to 14 or 18 MJ, respectively.","PeriodicalId":423813,"journal":{"name":"Animal Science and Food Technology","volume":"2002 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114086962","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}

Sows, the duration of pregnancy of which is more than 115 days, are disadvantageous in that they require additional costs for transfers from sector to sector before far rowing. Studies have been held using the breeding records of the Agricultural Open Joint-Stock Company \"Agro-Plant\" Kalitain Kyiv region. We have investigated into the duration of pregnancy of sows of large white breed and its changes with the age of sows, the repeatability and heritability ratios are determined in 128 randomly selected pigs with different lengths of the pregnancy period. All experimental sows were given the same feeding and keeping conditions. The experimental animals received wet feed. It has been established that the duration of pregnancy (from 106 to 122 days) is not constant and has significant fluctuations, which should be considered when developing technologies for the industrial production of pork. The sows in which during several far rowing the duration of pregnancy was shortened and averaged 112.3 days and the second group with extended pregnancy duration of 116.86 days have been identified. The duration of pregnancy of sows has rather high rates of heritability (from 0.47 to 0.72) and repeatability (from 0.17 to 0.74) which increase with their age. It is possible to select sows with a shortened and stable duration of pregnancy, the use of which will shorten the reproduction cycle, as well as increase the safety of piglets and reduce the costs related to additional transfers of pigs.","PeriodicalId":423813,"journal":{"name":"Animal Science and Food Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127397034","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 purpose of the research was to study the phenotypic consolidation of various breeding groups of dairy cattle (half-siblings, lines, breeds).It was established that the most consolidated by milk yield, the fat and protein content in milk, the age at first calving and the calving interval are groups of half-siblings (К A5 = 0,202) compared to the phenotypic consolidation of lines (К A5 = 0,035) and breeds (K A5 = 0,088). The most consolidated according to the studied characteristics are the groups of daughters of the bulls Nirvana 101709244 (К A5 = 0,317) and Tahoe 8189401 (К A5 = 0,331), lines of cows and related groups – Marshall2290977 (К A5 = 0,193) and J. Besn 5694028588 (К A5 = 0,103 ), as well as the cattle of Ukrainian Black-and-White and Red-and-White dairy breeds (K A5 = 0,144 and K A5 = 0,129, respectively). It was determined that the level of phenotypic consolidation increases with decreasing of genetic variation of the traits. On average, higher consolidation was observed for traits with low genetic variation (fat and protein content in milk).For milk yield the level of phenotypic consolidation was much lower. For the first calving age and the interval between 1 and 2 calves, the studied groups of animals can be classified on average as unconsolidated. The most consolidated in five traits are the half-siblings cows (the lowest level of the systematic hierarchical structure), and the much lower consolidated are cows of different lines and breeds (higher levels in the systematic hierarchy). Therefore, as the level of the breeding group increases, the degree of their phenotypic consolidation in the breed hierarchy decreases.","PeriodicalId":423813,"journal":{"name":"Animal Science and Food Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130597911","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}
