High-yielding cattle herds of dairy cows exist in Holland and Israel, meat breeds - in Argentina and Brazil, pigs - in Denmark and the USA, sheep - in Australia and New Zealand, poultry - everywhere. \u0000In Saudi Arabia, the government has taken a decisive course on progressive policies in agriculture. The Al-Safi company produces 75,000 tons of milk per year (7000 kg per cow). It has its own processing plant (300 tons per day). The company employs more than 1,100 people in 137 different positions on a competitive basis. The farm has more than 25000 head of cattle, 225 people work, which is 89 heads per person and 125 cows per milker. Many cows give 10000 kg of milk per lactation (more than 30 kg per day). There are 17 milking parlors and 370 milking machines. The technology of keeping animals includes 5 subdivisions - newborn calves, workshops for raising young animals (heifers, steers for fattening), and an inseminated non-calf workshop. \u0000The load per worker is 260 heads. People work from 5 a.m. to 10 a.m. and from 3 a.m. to 6 p.m., they are provided with showers, wall lockers, a washing machine, overalls and shoes, and personal hygiene products. \u0000To improve the gene pool of a closed population, artificial insemination is used. Every day, more than 30 calves are born at the farm, which are placed in cages (100 Ч 200 Ч 80 cm) of a calf house without walls. At the age of three months, they are transferred to a group up to a year, then heifers - to a group for fertilization, steers - for fattening. Netels are formed into a separate group. The program of uniform feeding of livestock is based on the use of silage and hay forage with a two-year supply, which ensured the stability and quality of forage, as well as crop rotation. For this purpose, there are silo facilities for 35,000 tons. Hay is harvested in bales or rolls. Organization of breeding and selection of animals is carried out according to a computer program. \u0000There are also similar high-tech enterprises in Israel, the USA, Holland and Canada. The talented people of Ukraine are not far behind the Arabs in terms of intelligence, the country's leaders are no stupider than princes and sheikhs, Ukrainian businessmen are no poorer than Arabs, although the sources of income are different. \u0000It is necessary to improve the management structure and the quality of the state apparatus, to increase punishment for inaction and fraud. The production and consumption of food determines the well-being of the people, which is so eagerly talked about \"above\", but there are few effective measures. Everyone must fight for the best together, using both domestic and foreign experience.","PeriodicalId":289036,"journal":{"name":"Animal Husbandry of the Steppe of Ukraine","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129447081","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 world tendencies and tendencies of growth of consumption of fish products are analyzed. It is noted that the main trend in the development of the fishing industry is the development of aquaculture. It is proved that in recent years in the field of fisheries of the Dnieper there is a significant decline in production (2.5–4 times). Over the last 10 years, 1/3 of farms have not been able to adapt to work in the new economic conditions and have become unprofitable. In 2020, 473.149 tons of fish products were grown in Dnipropetrovsk region, which is one of the lowest figures in recent years. Not a single kilogram of fish products was obtained in pools and growing ponds. \u0000Such facts clearly indicate the negative trends in aquaculture in the region. Growing fish is becoming a non-profit business. In the absence of any targeted state aid to fisheries, the latter will inevitably collapse. Commercial fishing (fishing) officially caught 1939.463 tons of fish and 1.131 tons of crayfish in the reservoirs of Dnipropetrovsk region. It is noted that the total value of these aquatic bioresources at the exchange price is only 10.76 million UAH. The cost of aquatic bioresources in Ukraine today is extremely low. This stimulates the development of commercial fisheries and promotes the growth of unaccounted and unaccounted for fisheries. The growing role of recreational (amateur) fishing in the use of aquatic bioresources of Ukrainian reservoirs is noted. It is proposed to introduce monthly, seasonal, annual permits for paid recreational and sport fishing: for the winter season – UAH 173; for the summer-autumn season – UAH 341.7; per year – UAH 504.9; for one month – UAH 56.1. \u0000The cost of a permit for the summer-autumn season for a float will be UAH 235.45, for a spinner – UAH 574.26. It is noted that the estimated amount of economic contribution of amateur fishermen of the Dnieper region only for fishing permits to the budget of Ukraine can be at least 10.000.000 UAH per year. This is quite comparable to the state's profit from commercial fishing in the reservoirs of Dnipropetrovsk region. Measures to support state fisheries in the Dnieper region, improve existing approaches to fisheries and aquaculture are proposed.","PeriodicalId":289036,"journal":{"name":"Animal Husbandry of the Steppe of Ukraine","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116928529","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}

Different amounts of RchSP in the rations were achieved by feeding grist from natural and roasted peas at a temperature of 105°C. \u0000When feeding the experimental ration with a reduced level of RchSP against the background of a decrease in the apparent intensity of digestion, which was manifested in a smaller amount of duodenal and ileocecal chyme, significant changes in the digestibility of SR, SZ and SZ were observed in the postruminal sections of the gastrointestinal tract.

The purpose of the research was to develop a program of selection measures to increase the productivity of pigs of the factory type \"Bagachanskyi\" of the large white breed. It was established that compared to 2015, the share of animals imported from other farms decreased from 4.3% to zero in sow pedigrees, and from 27.5% to zero in boar pedigrees.This is due to the fact that PAF \"Ukraine\" acquired the status of a breeding farm, and the pig herd of this farm was involved in the creation and approval of the factory type of pigs \"Bagachanskyi\". Therefore, after 2010, the importation of boars from other farms took place in a limited number and exclusively for breeding purposes, and after 2014, the stud farm completely switched to self-repair not only with pigs, but also with boars. Thanks to the purposeful breeding work in the herd on development indicators and meat qualities, the consolidation of repair young animals according to these characteristics reached the maximum level (the coefficient of variation is in the range from 0.33 to 1.62%).At the same time, the absence of a significant difference between families complicates the breeding work and reduces the opportunities for intrabreedheterosis. The use of index selection, including based on linear BLUP models, contributed to the achievement of a high level of indicators of reproductive qualities (+14.8-16.0% compared to the requirements for the elite class) without deterioration of indicators based on the characteristics of bacon thickness and the age of reaching a weight of 100 kg . When evaluating the genotype by the BLUP method, it was found that the most productive offspring in terms of reproductive qualities are predicted to be obtained from sows of the Ella family. At the same time, the most significant improvement will occur at the expense of the trait of nest mass, while the sows of the Beatrice family have the highest genetic potential for multifertility.

The experimental part of the work was carried out in the agricultural formations of the Odesa region. \u0000In the main diet, a certain amount of digestible protein and mineral substances was replaced by an appropriate amount of zoster, nitrogen-containing feed product MTM and urea. The diet of the I experimental group contained 25 g of zoster, the II experimental group – 50 g of MTM, the III experimental group – 10 g of urea, the control group did not contain any impurities. 50 g of MTM contained 25 g of zoster and 10 g of urea. Research on meat and wool productivity (live weight, absolute live weight gain; wool shear in physical weight and washed fiber, wool length) was carried out according to generally accepted methods. \u0000In order to determine the effectiveness of the use of East Friesian rams on Tsigai ewes, an experiment was conducted to study the milk yield of crossbred ewes and the intensity of growth of newborn lambs. In cross-breed lambs obtained from rams of the East Friesian breed and ewes of the Tsigai breed, the intensity of growth of live weight in the age aspect, slaughter qualities and amino acid composition of the meat were studied. The milk yield of crossbred dams was studied by the amount of milk obtained during the suckling period, during the period after the lambs were weaned, and during the entire lactation period. Meat and dairy productivity were studied according to generally accepted methods. \u0000The digital material was processed by the method of variational statistics according to V. P. Kovalenko et al. (2010). It was established that balancing the diet in terms of protein, minerals and vitamins due to feeding zoster, MTM and urea ensures an increase in live weight of 10-month-old goats by 2.9–7.2%, wool shearing in physical weight by 52.8–55.5 %, in washed fiber by 51.1–53.5 %. The use of rams of the East Friesian breed on ewes of the Tsigai breed contributes to the production of cross-breed animals with well-developed economic and useful traits. In cross-breed rams, compared to Tsigai rams, the pulp yield per 1 kg of pre-slaughter mass is 5.2 % higher, and the slaughter yield is 5.11 %. \u0000The high milk yield of cross-bred mothers contributed to better growth and development of lambs. During the period of growth from birth to yearling, the local young outnumbered the purebred Tsygayskii in terms of live weight: lambs by 16.9 %, yaks by 22.7 %, and by average daily growth by 18.1 % and 24.6 %, respectively.","PeriodicalId":289036,"journal":{"name":"Animal Husbandry of the Steppe of Ukraine","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124688520","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}
