Providing the population with quality and safe food, in particular meat, is one of the main tasks facing agricultural producers. An important role is assigned to pig breeding, since pigs are characterized by high fertility and precocity [1, p. 25]. The aim of the work was to assess the productive qualities ofpure-bred and hybrid sows when crossing with purebred boars. The studies were conducted in the pig farm "Slavyanka". Productive qualities of sows were assessed by multiple pregnancy, large young, milk production, weight of the nest at birth and on the 30th day at weaning, as well as by the level ofpigs’ safety. These studies showed that hybrid sows outperformed purebred sows (13.70±0.40) in multiple pregnancy (14.6±0.04 piglets). The milk content of purebred sows was lower by 4.73 kg or 10.50 % than that of two-breed hybrids. The mass ofpiglets’ nest at birth in crossbred sows when crossing with Pietrain boar outperformed the mass ofpurebred sows’ nests by 3.4 kg, or 17,60%. The output of business piglets was almost the same and amounted to 13.01 heads have hybrid sows and 12.05 heads purebred. Safety of piglets was, respectively, 90% and 87%. Two-breed hybrids significantly outperformed purebred sows by nest weight at weaning by 14.3%, the average weight of one pig by 9.42%. Thus, studies have shown that crossbred sows crossed by terminal boar of Pietren breed, outperformed purebred ones on many para-metres.

The aim of the article was to present the changes in the profitability of milk production in farms associated in EDF and situated in Poland and selected European countries in 2006–2012. It was found that after the Polish accession to the EU, the situation has improved for milk producers – economic and production results have risen. In 2008–2009, there was a significant deterioration in the profitability of milk production due to, among others, significant declines in milk prices. Since 2010, gradual improvement of the situation is observed. Similar changes occur in dairy farms in other European countries, such as Germany, France and the United Kingdom. This shows how big the interconnectedness between countries is and that the situation of agricultural producers in Poland does not depend only on the local and national market fluctuations, but primarily on fluctuations in the European and global markets.

This article presents the analysis of the state of dairy cattle industry and its short-term development prospects in connection with the crisis of 2020.  For the purposes of objective assessment, we considered the period of 2015-2019 and presented the dynamics of the main statistical indicators with significant state support (grants, subsidies, etc.) for agricultural producers. In 2019 the total amount of disbursed funds was more than 1.4 billion rubles, most of which were directed to the development of dairy cattle breeding. According to the results of 2019, 73.9% in milk-production structure accrue to personal subsidiary farms, 19.6% - to agricultural organizations and 6.5% - to private farms. The significant share of produced milk in the Stavropol territory accrues to personal subsidiary farms; at the same time, the increase in milk production was 26.5% (643.8 thousand tons). Alongside the reduction of livestock in the general population of milk cattle in the Stavropol territory it is obvious that the genetic potential of cows increases due to the decrease of low-productivity animals and wide-scale import of high-producing breeding heifers, both from abroad and domestic market. The topical problems of the industry are low reproductive qualities of cows (the output of calves in agricultural organizations is only 75%), the violations of feeding technologies and animals housing due to insufficient availability of specialists. In general, industry development rate is quite high and has significant potential for production increase in short-term prospect, provided that the existing state-support programs continue. The most relevant trends are the increase of genetic potential of productivity in Stavropol livestock population, the adoption of state-of-the-art technologies for livestock keeping and feeding, as well as the development of farming and the niche of organic products.

ABSTRACTIn three experiments the effects of giving Hereford × Friesian cows 61 to 64 MJ/day of metabolizable energy in the last 8 weeks of pregnancy, followed by either 49 to 56 (L) or 85 to 100 (H) MJ/day for the first 8 weeks of lactation, were determined. A further comparison was made in experiment 3, in which energy intakes were restricted to 46 and 64 MJ/day (M) in the two periods respectively. The L and M groups had a similar average weight loss of approximately 55 kg over winter whereas the H groups maintained their weight. The L and M treatments had a negligible effect on milk production at 3 weeks post calving but they caused a significant depression at 6 weeks in experiments 2 and 3. Milk energy and protein concentrations were reduced in all three experiments. Calf growth was similar on both treatments in experiment 1 but was 9 to 13% lower in experiments 2 and 3 for the L and M groups compared with the H group. Reproductive performance was not significantly affected. There was a substantial increase in milk production for all groups on turnout to grazing. This was greater for the L and M groups so that their summer milk production was almost equal to that of the H group. Cows from L and M groups gained more weight at pasture. By the end of the trials cows and calves from all treatments had similar weights except in experiment 3, when cows from the L and M treatments were still lighter than those from the H treatment.

Sustainability Principles

The study is dedicated to the issue of implementing rules of sustainable development on farms. Research was conducted on 310 farms. The farm classification criterion was the education of the farm manager. Farms in four provinces were analyzed: Kujawsko-Pomorskie, Mazowieckie, Lubelskie, and Wielkopolskie. The aim was to determine the knowledge and scope of applying sustainable development in farming, depending on the farmer's education level. The research consisted of determining the importance attached by farmers, depending on their declared level of formal education, to features of a sustainable farm and advantages of this mode of management for the environment, the society, and agricultural producers themselves. It was assumed that the higher the farmer's education level, the better the familiarity with sustainable development principles and their practical application. It was found that depending on the agricultural producer's education, the importance attached to individual variables characterizing a sustainable farm varied. In terms of environmental advantages, the most important feature was water protection; among benefits for the society, safe food was considered to be of the highest significance, while for producers, the most important was a higher income. The research results did not make it possible to unambiguously state that university education determines farmers' familiarity and compliance with sustainability principles. In some cases, farmers, who had good knowledge of sustainable agricultural practices, failed to apply them in their operations.

SummarySix pairs of gilts were taken at first mating. One of each pair was given about half the A.R.C. recommended amounts of protein and energy during pregnancy and lactation until she became anoestrus (thin group). The other gilt of each pair was given the same amount of protein, but double the amount of energy (standard group).All the thin sows lost condition and became infertile. Their appearance conformed to that of sows with the ‘thin sow syndrome’. This took up to three reproductive cycles. There was no clear effect on the number of piglets born, but the litters of the thin sows contained an increasing proportion of small piglets. One of the thin sows died in her second pregnancy. The standard sows performed well producing an average of 10·3 piglets weighing 1·4 kg over three parities.There were no differences between the two groups in their digestive efficiency. The thin sows retained less nitrogen in the later stages (days 80–100) of their first pregnancy than did the standard sows.There were no differences between the groups in milk production during the first lactation when litters were standardized at eight piglets. There was some evidence that in the second lactation the thin sows secreted less fat and lactose.The five remaining thin sows were repleted at the end of the experiment when their average weight was 96 kg. They were mated as quickly, produced litters which were as large, and piglets which were as heavy as those produced by the standard sows whose mating weight was 182 kg.

The research was conducted to study the effect of the use of sunflower meal (SFM) as a protein source in Awassi ewe feeding diets on milk production, milk components, and biochemical blood characteristics. In the study, 18 Awassi ewes were used, ranging in age from (3-4) years, with an average weight of (49) kg. The ewes were randomly divided into three equal groups in their weight and milk production rates. The first group ewes were fed on a standard diet consisting of soybean meal, yellow corn, barley, wheat bran, wheat flour, salt, and limestone. The sunflower fraction replaced the soybean meal in the diets of the second and third groups by 7 And 14 %, respectively. The feeding period lasted for (90) days. The results showed that the ewes of the second group were the highly significant difference at a level (p ≤ 0.05) in daily and total body weight and final weight. The daily milk production rate in the second treatment was significantly different at a level (p ≤ 0.05), as it reached 0.601 kg/day from the third treatment, which reached 0.513 kg/day and mathematically from the first treatment in which the daily milk production reached 0.541 kg/day, the same significant difference was found in the second group of treatment in total milk production rates compared to other treatments was (48.69, 54.09 and 46.17) kg/ewes for the three treatments, respectively. The study also showed that the differences between the first (standard) treatment and the treatments in which sunflower was used were not in the rates of ratios of (fat, protein, lactose and total solids) of milk, while a significant increase at a level (p≤0.05)  was observed in the produced quantities of the protein (33.29 g / day) and the fat (43.09 g / day) of ewe milk of the second treatment compared to the quantities produced of the protein (27.44 g / day) and the fat (38.42 g / day) of the ewe milk that consumed the third diet. The analysis of biochemical blood samples did not differ significantly between the three treatments. The study recommends conducting research using a percentage higher than 14% for sunflower meal and knowing its effect on production, and conducting other studies to find out the effect of sunflower meal on the concentration and quality of fats in the tissues of carcasses and milk produced, in addition to conducting digestion experiments and knowing the rumen environment in Awassi sheep.

The aim of the present study was to obtain relevant results related to the basic indicators of fertility and milk yield of Simmental cows, in production conditions on farms of agricultural producers, using appropriate mathematical and statistical procedures, i.e. to determine the influence of bull sires originating from Serbia, Austria and Germany on the implementation of the main breeding program and improvement of production traits of Simmental cows on the territory of Sumadija district. The study of the effect of bull sires who are originally from Serbia, Austria and Germany on performance traits of Simmental cows included a total of 303 cows in first three lactations. Milk production of cows descendents of bulls from the German population was higher compared with the production of cows originating from Austria in the first lactation by 58.29 kg and in the third by 67.72 kg, but in the second it was lower by 12.31 kg. The variability of age at first calving ranged from 766.93 (cows progeny of domestic bulls) to 813.06 days (cows progeny Austrian bulls). Average duration of service period had the interval of variation of 86.80 in cows from domestic bulls in the third lactation to 109.88 days in cows originating from Austrian bulls in the first lactation.
