The purpose of the research is – to develop requirements for creating comfortable conditions for keeping farm animals, taking into account EU standards, during milk production on farms. Research methods. During the development of requirements for the creation of comfortable conditions for keeping farm animals, taking into account EU standards, in the process of milk production on farms used the following basic regulations: Council Directive 98/58/EU, Council Directive 91/629/EU, Council Directive 92/46/EU, Commission Directive 89/362/EC. Requirements in the field of milk production, adapted to EU standards, are systematized by the following components: keeping, feeding, watering animals, milking cows, milk cooling, manure removal, creating a microclimate, veterinary care. Research results. In practice, during milk production it is necessary to create free, comfortable conditions for keeping cattle. Convenient access of service personnel to the place of calving of cows should be provided. In the conditions of the maternity ward, the technological areas should be 8-10 m² per cow. Young cattle, including calves, should be provided with a clean and dry rest area, protected from drafts. According to EU regulations, calves up to eight weeks of age can be kept in individual cages or in group cages. According to EU Council Directive 97/2, calves older than 8 weeks of age are kept only in group cages. In accordance with the EU Directive 97/2 technological areas for keeping young cattle with a live weight of up to 150 kg - must be at least 1,5 m² / head., Live weight 150 - 220 kg – 1,7 m² / head., Live weight 220 kg and more – 1,8 m² / goal. Technological areas for keeping animals with a live weight of 200 to 500 kg - from 2,7 to 4,7 m² / goal. The feeding front for young cattle with a live weight of 200 to 500 kg is from 0,4 to 0,6 m / goal. The technological area in the section per cow must be at least 6 m² / head. Rational sizes of boxes for rest of cows: width 1,2 m, length (near a wall) - 2,6 m, length (in paired boxes) - 2,45 m, height of a protection of a box - 1,1 ± 0,05 m, an inclination boxing floor towards the manure passage 5 ± 1%, the height of the boxing floor above the level of the manure passage 0,2 – 0,25 m. The width of the rest area of cows must be at least 6 m. In accordance with EU Council Directive 98/58 must be provided free access of animals to feeders and feed. EU Commission Decision 97/182 states that priority should be given to the feeding of whole milk substitutes when feeding calves. A feeding front for cows must be provided – 0,7 ± 0,05 m. In accordance with EU Council Directive 98/58, free access of animals to drinking troughs and water must be ensured. According to European standards, the total bacterial contamination of milk should be - ≤ 300 thousand KUO / cm³, the number of somatic cells in milk - ≤ 400 thousand /cm³. Drainage of wastewater from milking parlors, household premises of the farm is carried out using a separate from the manure removal system - sewer system. The bactericidal phase of fresh milk is 4 hours, no later than this period you need to start processing milk into dairy products. The depth of the manure channel in the livestock building should be 8 - 20 cm, the sides of which are located at right angles to the surface of the channel. The minimum width of the manure passage for cows should be 2,7 m. An acceptable level of air temperature for cows during the year from minus 10 °C to + 25 °C at a relative humidity of up to 80 %. Periodically carry out preventive veterinary measures, weighing animals, trimming the hooves of limbs in cows 2-4 times a year, monthly examination of cows for mastitis using mastitis detectors. Conclusions. For the first time in Ukraine, requirements have been developed to create comfortable conditions for keeping farm animals, taking into account EU standards, during milk production on farms. Requirements adapted to EU standards in the field of milk production are systematized by the following components: keeping, feeding, watering dairy cattle, milking cows, cooling milk, manure removal, creating a microclimate, veterinary care.

Scientific researches have been proved that a more complete disclosure of the productive potential of farm animals is possible when they use a full range of different feed, vitamins, premixes and different feed additives. Currently, all these components are given to animals in the form of a compound feed, the preparation of which is carried out in crumbled or pelletized form. Preference is given to pelletized feed, because it has great advantages over crumbled feed. It has been noted that when feeding young cattle with pelletized feed the average daily of live weight has increased by 6,1 % than when feeding with crumbled feed. When feeding piglets with pelletized feed the increase was 8,2 % more. Feeding fur-bearing animals with dry pelletized feed can increase economic efficiency by reducing the cost of the diet by 1,44 times. The results of testing the equipment of LLC “Doza-Agro” for the production of pelletized feed in terms of its quality have been presented in the article. Evaluationof the workflow of the equipment has been carried out as part of the compound feed plant series “Profi ” located in the village Sultan-Saly in the Rostov region. The description of the compound feed plant and its elements has been given, the methods according to which the research was carried out have been described, and the laboratory equipment for determining the quality indicators of the feed has been presented. The quality of macronutrients grinding feed crusher DZM-6, the quality of mixing feed elements in the mixer SLG-2A and the quality of feed pellets obtained in the granulator DG-10Nhas been evaluated. Comparison of the obtained data with the values prescribed in the GOSTs has been shown compliance of the prepared granules with the requirements of standards.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Milk is an important intake to meet nutritional needs. Both consumed by children, and adults. Indonesia has many producers of fresh milk, but it is not sufficient for national milk needs. Data mining is a science in the field of computers that is widely used in research. one of the data mining techniques is Clustering. Clustering is a method by grouping data. The Clustering method will be more optimal if you use a lot of data. Data to be used are provincial data in Indonesia from 2000 to 2017 obtained from the Central Statistics Agency. The results of this study are in Clusters based on 2 milk-producing groups, namely high-dairy producers and low-milk producing regions. From 27 data on fresh milk production in Indonesia, two high-level provinces can be obtained, namely: West Java and East Java. And 25 others were added in 7 provinces which did not follow the calculation of the K-Means Clustering Algorithm, including in the low level cluster.

Abstract Fifty intact male Barbarine lambs were used to assess the effects of restricted feeding and re-alimentation on intake, growth and non-carcass components. Five lambs were slaughtered at the start of the trial, the remainder were randomly allocated into three groups. One group was offered only stubble grazing (low: L), another, also on stubble, received, indoors, an average of 80 g dry matter (DM) of soya-bean meal per day (medium: M); the third group was kept indoors and had free access to hay and 450 g of concentrate per day (high: H). At the end of this restriction period (70 days), five lambs per group were slaughtered. The 10 remaining animals in each group were divided into two groups receiving concentrate and hay ad libitum. The crude protein content (CP) of the concentrate was 160 and 210 g/kg DM for the two treatments, respectively. At the end of the trial all animals were slaughtered at 37·61 ± 2·05 kg live weight.In the restriction period, sheep from the H group had a significantly higher growth rate (108 g/day) than L group (61 g/day) with M intermediate. The empty body weight (EBW) as well as carcass weight were significantly higher in H than in restricted sheep. Digestive tract components and liver weight were the same for all treatments. However, skin weight was significantly (P < 0·01) affected by dietary treatment. The heart and lungs were also heavier in H lambs than in the two other groups. Conversely, the relative weights of gut and liver as proportion of EBW increased in restricted lambs, while that of skin and red organs was not affected by diet.In the re-alimentation period and with both CP levels, the compensating animals showed the same growth rate as the previous unrestricted ones. At the end of this period, organ weights, in both absolute and relative value, were comparable among lambs of the three nutritional histories and two CP level. The absolute and proportional daily gains were similar in all animals for visceral and external organs, but they were significantly higher in H lambs than in L and M ones for the omental and mesenteric fat and testis.

Friesian Cows

SummaryTwenty-four Friesian cows were allocated to one of four diets for weeks 3–14 of lactation following 2 weeks on a common diet. The diets (kg air-dry feed/day) were 7–2 kg hay and 10·8 kg either starchy or fibrous concentrates (60S and 60F) or 3·5 kg hay and 14·0 kg either starchy or fibrous concentrates (80S and 80F). Rumen samples were taken by stomach tube in weeks 10 and 12 of lactation and the digestibility of the diets was measured with four cows per treatment during weeks 13 and 14. The digestibility of the same feeds was also measured in sheep at maintenance.The principal carbohydrate constituents of the concentrates were barley, wheat and cassava in the starchy concentrates and citrus pulp, sugar-beet pulp and wheat feed in the fibrous concentrates. The concentrates were designed to have similar concentrations of metabolizable energy (ME) and the diets were planned to provide similar intakes of digestible energy and crude protein.Milk yield and composition were very similar for treatments 60S and 60F. With the higher proportion of starchy concentrates (80S), milk yield was about 20% greater than on 60S, fat concentration fell severely but protein and lactose concentrations were unaffected. With the higher proportion of fibrous concentrates (80F), milk yield and the protein and lactose concentration were similar to values on 60F but fat concentration was lower, though not nearly so low as on 80S. Milk energy yield was reduced by the higher proportion of concentrates but was unaffected by type of carbohydrates. Live-weight changes were small.In both the sheep, consuming at maintenance, and the lactating cows consuming at about 3 times maintenance, digestibility of dry matter, organic matter and energy was higher with the higher concentrate diets but was unaffected by type of concentrate. The digestibility of fibre was greater with the fibrous concentrates but the effect of level of concentrate inclusion was inconsistent. Digestibility coefficients were consistently lower for the lactating cows than for the sheep.The proportion of acetic acid in the rumen volatile fatty acids in the cows was higher and the proportion of propionic acid was lower with the fibrous concentrates. The differences were much greater with the higher proportion of concentrates.During weeks 15–22 of lactation the cows were reallocated to concentrate treatments and given hay ad libitum. Hay intake was about 1 kg/day higher with the fibrous concentrates but the difference was not significant. Hay intake fell by about 0·6 kg/kg concentrate intake for both concentrate types. No significant differences in milk yield or composition were established, probably because of incomplete adaptation even after 8 weeks.It is concluded that at concentrate intakes of about 10 kg/day, the source of carbohydrate in the concentrates has little effect on milk production when the concentrates are of similar ME concentration. However, at higher levels of concentrate inclusion, although the diets may have similar ME concentrations, important differences in the yields of fat, protein and lactose occur due to carbohydrate source and these can be related to differences in rumen fermentation.

AbstractAs future climate challenges become increasingly evident, enhancing performance resilience of farm animals may contribute to mitigation against adverse weather and seasonal variation, and underpin livestock farming sustainability. In the present study, we develop novel seasonal resilience phenotypes reflecting milk production changes to fluctuating weather. We evaluate the impact of calendar season (autumn, winter and spring) on animal performance resilience by analysing 420,534 milk records of 36,908 milking ewes of the Chios breed together with relevant meteorological data from eastern Mediterranean. We reveal substantial seasonal effects on resilience and significant heritable trait variation (h2 = 0.03–0.17). Resilience to cold weather (10 °C) of animals that start producing milk in spring was under different genetic control compared to autumn and winter as exemplified by negative genetic correlations (− 0.09 to − 0.27). Animal resilience to hot weather (25 °C) was partially under the same genetic control with genetic correlations between seasons ranging from 0.43 to 0.86. We report both favourable and antagonistic associations between animal resilience and lifetime milk production, depending on calendar season and the desirable direction of genetic selection. Concluding, we emphasise on seasonal adaptation of animals to climate and the need to incorporate the novel seasonal traits in future selective breeding programmes.

The determining factor in increasing the productivity of farm animals is the provision of comlete feeding of animals through feed additives. Among the functional feed additives containing essential trace elements, a special place under the conditions of the Amur region is given to microadditives of selenium, iodine and cobalt. The Amur region belongs to the biogeochemical region in which the defi ciency of I, Se and Co in feed is from 80 to 95 % compared to the average Russian indicators. The purpose of the work was to compare the eff ect of feed additives made from red alga Ahnfeltia, soy protein asparaginates separately and together with the drug “Creamino” on the growth, development and metabolism of young cattle. Under the conditions of the Amur region on the basis of their own experimental data in the rearing of young cattle, the eff ectiveness of the use of the drug “Creamino” and red alga Ahnfeltia has been scientifi cally justifi ed. The conducted scientifi c and economic and physiological experiments allowed us to determine the eff ect of red anfel on the growth and development, metabolic processes of replacement heifers and the growth rate of steers when they were fed soy protein asparaginates together with the drug “Creamino”. The evaluation of the economic effi ciency of feeding heifers I, Co and Se in organic form as part of soy protein asparaginates and red alga Ahnfeltia has shown a higher economic eff ect per 1 head per day in the 2nd experimental group, where the level of profi tability was 28,6 %. The results of the research and production experiment on steers have shown that from an economic point of view, it is advisable to use I, Co and Se in their rations in the form of soy protein asparaginates together with the drug “Creamino”, feeding of which can signifi cantly increase the economic eff ect, which is 1 head per day of 4,47 rubles with a profi tability level of 31,0 %.

SUMMARY1. Scottish Half-bred ewes carrying twin foetuses were fed individually to make live-weight gains in the last six weeks of pregnancy of (1) 20%, (2) 10% and (3) 0% of their live weight in week 14 of pregnancy. In lactation the ewes were fed ad libitum. The lambs were removed 12 to 16 hr after parturition and the ewes were machine-milked twice daily for the first six weeks of lactation.2. Total birth weights per ewe of twin lambs from the treatments were (1) 10·10 kg, (2) 9·44 kg and (3) 8·18 kg and differed significantly.3. The level and pattern of voluntary intake in lactation did not differ significantly between the treatments. Total dry-matter intakes in the six weeks of lactation were (1) 121·9 kg (2) 105·9 kg and (3) 109·5 kg.4. The pregnancy treatments affected the level of milk production and the shape of lactation curves. The total yields in the first six weeks of lactation were (1) 58·8 kg, (2) 43·5 kg and (3) 26·9 kg. Higher contents of fat and protein and the lower content of lactose in the milk from treatment-3 ewes on days 1 and 3 of lactation indicated a slower onset of lactation in these ewes. Between days 7 and 35 of lactation the contents of fat and SNF were lowest on treatment 3 but the differences were not significant.5. The live-weight changes in lactation, which were in inverse order to the gains in late pregnancy, were (1) 3·4 kg, (2) 5·5 kg and (3) 9·5 kg.

AbstractSeventy high genetic merit Holstein heifers were used in two experiments to investigate (1) the effects of plane of nutrition and diet type during the pre-pubertal period and (2) the effects of plane of nutrition during the post-pubertal period on metabolic hormone concentrations, growth and milk production. In experiment 1, treatment 1 and 2 heifers were given food to achieve a live-weight gain of 0·70 and 0·95 kg/day from 3 to 10 months of age on a grass silage based diet, while treatment 3 heifers were given food to achieve 0·95 kg/day on a barley straw/concentrate diet. During the pre-pubertal period, heifers reared on treatment 1 had significantly higher growth hormone(GH) concentrations (ng/ml per 1 h) than heifers reared on treatment 2 (P < 0·01) and had significantly lower insulin concentrations than heifers reared on treatment 3 (P < 0·01). Heifers reared on treatment 1 had significantly lower insulin-like growth factor 1 (IGF-1) concentrations than those reared on treatment 3 (P < 0·01). At 10 months of age heifers reared on treatment 1 were of lower condition score (P < 0·01) than those on treatment 2 and had a smaller heart girth diameter (P < 0·01) than those on treatments 2 and 3. During the first lactation, milk yield and composition produced by the heifers was not significantly affected by treatment. In experiment 2, treatment A heifers were given, from 14 to 24 months of age, a low plane of nutrition to allow a live-weight gain of 0·65 kg/day on a grass silage and grass based diet during the winter and summer periods respectively. Treatment B heifers were kept on a high plane of nutrition to allow a live-weight gain of 0·90 kg/day on the same forage along with concentrate supplementation. During the rearing period, GH and IGF-1 concentrations were not significantly affected by treatment. Treatment A heifers weighed less before calving (P < 0·05), had a lower condition score (P < 0·01), and had a smaller heart girth diameter (P < 0·01) than those on treatment B. During the first 10 weeks of lactation, heifers on treatment A had a higher silage dry matter intake and lost less weight (P < 0·05) than those on treatment B, however, by 20 weeks of lactation these effects had disappeared. Milk yield and composition during the first lactation were not significantly affected by treatment. Overall, the findings of experiments 1 and 2 did not show any beneficial effects of higher weights at first calving in high genetic merit Holsteins and therefore indicate that accelerated growth in the pre- or post-pubertal period may not be required.
