dc.descriptionThe aim of research was to determine the optimal dose of Cobalt mixed ligand complex combined with Copper sulphate, Zinc and sodium selenite in feeding highly productive cattle of Holstein breed of German breeding in the dry period and in the lactation periods and to establish their impact on cows milk productivity. Scientific and economic research on the effects of different doses of Cobalt mixed ligand complex was conducted in the conditions of "Terezine" enterprise of Bila Tserkva, Kyiv region for dairy cows of Holstein breed of German breeding. Five groups of cows, ten animals each, were formed on the basis of counterparts to investigate the complex efficiency. The cows were fed the same ration during the preparatory and experimental periods. The difference in feeding was that during the experimental period, within 60 days of dry period and the lactation periods, the control group cows were fed with preparatory period premix containing Cobalt mixed ligand complex combined with Copper sulphate, Zinc and sodium selenite, the doses of which covered the deficiency Cobalt, Zinc and Copper by 100 %, Selenium content made 0.3 mg/kg of dry matter (DM). The dosis of Cobalt mixed ligand complex covering the lack of this element by 85, 70, 55 and 40 % were added to the feed concentrate. During the study of the effect of organic Cobalt on milk productivity we developed identical feeding rations for cows with a capacity of 8.000 kg per lactation concidering their productivity level and physiological condition. The structure and nutritional value of the ration was changed during the entire production cycle, taking into account the energy and nutritional value. The rations for cows were developed considering research data and recommendations using the method of feed rationing per average animal of a homogeneous group taking into account the fact that cows should be given as much feed as they can eat without remnants during the first two months of lactation. Succulent and concentrated feed increased gradually from the tenth day of lactation and by the third month of lactation the diet nutritional value was adjusted to normal daily ratio according to the actual daily yield. From the third to the sixth month of lactation cows rations made up 90 % of the previous level nutrient value, from the seventh to ninth – 75 %, from the tenth month of lactation – 60 %. Dry cows were fed with bulky feed (hay, haylage) with the addition of 1–2 kg of feed concentrate. In the second half of the dry period silage was introduced gradually and feed concentrate reached 4 kg per head per day. From 5 th to 50 th day of lactation cows were fed wet mash-up, with a gradual increase in the level of concentrated feed (but no more than 50–53 % in the nutrient value) in order to increase cows productivity to 35–39 kg of milk per day. During this period the animals health restored and their appetite increased. The concentration of energy in 1 kg of dry matter was maintained at the level of 1.02 feed units, protein – 112.0 g. In the second phase of lactation (101–206 days) the level of bulky feed in the diet increased and high-quality straw was included as as low-energy feed used to balance wet mash-up for its crude fiber to stabilize rumen function and to increase microorganisms activity. Milk yield decreased in the third phase of lactation (201–305 days) and the cows need for nutrients reduced accordingly. It has been found out that the experimental cows milk production indices in different lactation periods depend on the intake of Cobalt mixed ligand complex. While first calved cows milk yield did not differ significantly in the preparatory period ten days prior to dry period, the average daily milk yield varied in the milking period depending on Cobalt level in the rations. The highest yield of milk fat during the periods of milking, milk production and lactation decrease as well as in 305 days of lactation was in the experimental groups cows. Above average yield of natural fat and 4 % fat in all the tested lactation periods was obtained from experimental group 3 cows. In particular, during milking period the yield was higher compared to the control, respectively, by 1.5 kg . The advantage of the experimental groups cows for 4 % fat milk production in the first 305 days of lactation was also significant as compared to the control group and amounted 230 kg or 3.3 % . Thus, the highest milk production in the studied lactation periods and in the lactation for the whole was in the experimental group 3 cows which received rations where the lack of Cobalt was covered by 70 %. The most distinguished increase in milk production was observed in group 3 cows during milking period with slight decrease in the periods of milk production and lactation compared to the control..uk_UA
dc.description.abstractНа підставі даних, отриманих під час проведення науково-господарського досліду, встановлено, що найбільший вплив на величину надою і якість молока високопродуктивних корів голштинської породи в сухостійний період і за періодами лактації мала кормосуміш до складу якої вводили дозу змішанолігандного комплексу Кобальту, що забезпечила зниження нестачі Кобальту в раціоні на 70 %. За усунення нестачі Кобальту на 100 % від корів за 305 днів лактації отримано 7690 кг молока. За зниження нестачі Кобальту на 85 % надій корів зріс на 210 кг (Р <0,01), 70% - 600 кг (Р<0,001), 55% - 320 кг (Р<0,01), 40% - на 206 кг. Вміст жиру і білка в молоці збільшився на 0,01 – 0,03% за зниження нестачі Кобальту на 55-85% порівняно із контрольною групою. На основании данных, полученных при проведении научно-хозяйственного опыта, установлено, что наибольшее влияние на величину удоя и качество молока высокопродуктивных коров голштинской породы в сухостойный период и по периодам лактации имела кормосмесь, в состав которой вводили дозу смешаннолигандного комплекса Кобальта, что обеспечило снижение недостатка Кобальта в рационе на 70 %. При устранении недостатка Кобальта на 100 % от коров за 305 дней лактации получено 7690 кг молока. При снижении недостатка Кобальта на 85 % удой коров возрос на 210 кг. Содержание жира и белка в молоке увеличилось на 0,01–0,03 % при снижении недостатка Кобальта на 55–85 % по сравнению с контрольной группойuk_UA
