Исследования по изучению влияния нетрадиционных кормовых добавок на химический состав мяса бычков симментальской породы были проведены на базе крестьянского хозяйства «Лонкур» в Сунтарском районе Республики Саха (Якутия). В статье представлена оценка эффективности кормовых добавок, приготовленных из местного природного сырья (50 и 100 г хвойной муки, 0,7 г/кг живой массы цеолита хонгурина и 35 г кемпендяйской соли). При анализе данных установлено, что опытные группы, получавшие кормовые добавки, имели лучшие показатели по убойному выходу и качеству мяса. Изучение химического состава мяса было проведено в соответствии с общепринятыми методиками. Было показано, что образцы мяса опытных групп превосходили контрольную группу по содержанию белка на 0,64 и 0,24%, жира — на 2,60 (P>0,999) и 1,73% (P>0,99), кальция — на 13,47 и 8,39%, фосфора — на 20,00 и 10,00%, железа — на 5,98 и 3,04%, меди — на 13,33 и 6,67%, магния — на 9,84 и 5,71%, селена — на 12,50 и 10,63%, витамина А — на 10,00 и 5,00%, витамина С — на 50,00 и 25,00%, витамина Е — на 33,33 и 11,11%, витамина В1 — на 6,25 и 3,13%, витамина В2 — на 30,77 и 15,38%, витамина В3 — на 11,43 и 7,14% соответственно. По накоплению цинка, свинца и кадмия в мясе опытных групп наблюдалась противоположная тенденция, связанная с сорбционными свойствами природных цеолитов. Полученные результаты показали перспективность использования нетрадиционных кормовых добавок в кормлении молодняка скота при производстве мяса в условиях Якутии. The investigation took place at the Krestyanskoe Khozyaystvo “Lonkur” (farm) in the Suntarskiy rayon (district) of the Republic of Sakha (Yakutia). The effect of non-conventional feed additives was analyzed on meat chemical composition of Simmental bull calves. The article reports on the effectiveness of feed additives made from the local natural raw materials (50 and 100 g of conifer flour, 0.7 g per 1 kg of body weight of Hongurin’s zeolite and 35 g Kempendyai salt). The groups consumed feed additives showed the best characteristics of slaughter weight and meat quality. Meat chemical composition was tested according to the Standard techniques. The beef obtained from two experimental groups exceeded the control in protein by 0.64 and 0.24%, fat — by 2.60 (P>0.999) and 1.73% (P>0.99), Ca — by 13.47 and 8.39%, P — by 20.00 and 10.00%, Fe — by 5.98 and 3.04%, Cu — by 13.33% and 6.67%, Mg — by 9.84 and 5.71%, Se — by 12.50 and 10.63%, vitamin A — by 10.00 and 5.00%, vitamin C — by 50.00 and 25.00%, vitamin E — by 33.33 and 11.11%, vitamin B1 — by 6.25 and 3.13%, vitamin B2 — by 30.77 and 15.38%, vitamin B3 — by 11.43 and 7.14%, respectively. Since natural zeolites exhibit good adsorption properties the beef accumulated less Zn, Pb and Cd. The results proved high efficacy of the non-conventional feed additives used in this study.

Intensive pig breeding implies, among other things, the use of complete mixes in their diet in correspondence with the animals? age and purpose. In the course of a threeyear period (2007-2009) the accredited laboratory of the Department for Nutrition and Botanics of the Faculty for Veterinary Medicine, Univerisity of Belgrade, analysed 65 fodder mix samples from the territory of Serbia intended for the diet of all categories of pigs, namely: 6 samples of complete mixes for the diet of pregnant sows and gilts, 9 samples of complete mixes for the diet of nursing sows and boar, 4 samples of complete mixes for enhanced diet of piglets, 13 samples of complete mixes for piglets in programme I up to 15 kg, 12 samples of complete mixes for piglets in programme II from 15-25 kg, 10 samples of complete mixes for growing pigs in fattening programme I from 25-60 kg, and 11 samples of complete mixes for pigs in fattening programme II from 60-100 kg. The analyses covered the contents of the elementary nutritive matter and the obtained results were compared with the quality conditions prescribed under the Regulations on the quality of animal feed (Official Gazette of the Republic of Serbia No. 41/09). It was established that there were certain deviations with regard to the values presented in the Regulations on the quality of animal feed (Official Gazette of the Republic of Serbia No. 41/09) in the average protein content in complete mixes for piglet diet II, 15-25 kg (17.89?1.19%) and in the mixes for growing pig diet II, 60-100 kg (13.95?0.53%). The established average fat content was lower in the mixes for enhanced piglet diet (5.99? 0.72%) and in mixes for piglet diet I, up to 15 kg (4.95?1.41%). A higher average cellulose content (4.08?0.73%) was established in mixes for enhanced piglet diet. Furthermore, significant differences from the values prescribed under the Regulations were established in certain samples. The established differences in the chemical composition of certain samples of the examined mixes without a doubt indicate the need for constant and multilevel monitoring of raw materials and finished products in order to preserve health and to ensure the best possible utilization of the production potential of animals.

Bull Calves

The hides, obtained from the slaughter of beef cattle, are valuable raw materials for the leather industry. Their value is determined by thickness, size, density, elasticity and other technological properties, development of subcutaneous fat and connective tissues which depend on breed, sex, age, conditions of animal keeping, climate, its temperature and humidity conditions, feeding. 5 groups of bull-calves of Ukrainian Beef, Hereford, Aberdeen Angus, Charolais and Simmental breeds (15 head) were formed in accordance with the methods at "Polyvanivka" experimental farm. Ration of feeding was similar for all the groups and consisted oftypical feed for steppe zone of Ukraine. In summer green feed in structure of diet was 25%, roughage– 33%, 42% of concentrates and in winter succulent – 23%, roughage – 18%, grain – 41%, herbal pellets of alfalfa – 14%. Access to food was free (feeding space – 1 meter), eating of feed – good (97-98%), they consumed 7.5 feed units and 800 g of digestible protein. The average daily gains of live weight were within 1 kg per head. Clinical and haematological parameters showed that all the bull-calves were physiologically healthy. The hidesof bull-calves at the age of 12 months were classified by weight as heavy (more than 25 kg). Yield of bull-calves’ hides of Hereford, Aberdeen Angus and Charolais breeds was the highest at the age of18 months, Ukrainian Beef and Simmental – at 30 months of age. This figure is not dependent on breeds of animals, but on weight of hides. In accordance with the habitus the hides of Ukrainian Beef, Charolais and Simmental bull-calves were longer, and Hereford exceeded analogues in width. Hides of Ukrainian Beef and Charolais cattle predominated by area. In our research, the thickness of the hides of animals with age naturally and consistently increased in all standard points: atthe elbow from 3.2 to 7.7 mm, at the last rib – from 3.2 to 7.4 mm, on sacrum – 4.7 to 8.8 mm. That is, during the period from 12 to 30 months of age thickening of hides at the elbow was an average of 2.4 times, at the last rib – 2.3 and sacrum – 1.9-fold (P <0.99). The chemical composition of hides in all the age periods remained stable. But tendency to reducing the proportion of water and increase of the fat content was noticeable with age. The share of protein and ash increased, but much slower. It is clear that weight of hides, their length and width, area and thickness which characterize the product properties and chemical composition don’t determine a high quality of raw hides. In this context we brought the hides of the investigated bull-calves in UkrNIIKP, where they were processed in the chrome-tanned leather for shoe upper at the experimental factory of the institute. The leather had a smooth, flat front surface and was full, soft, elastic, without hairinessin the final form. The findings indicate the differences between cattle of different breeds on expenditure of raw hides at production of leather for shoe upper by the current technology. More pronounced saving in raw materials was obtained at the processing of hides of Ukrainian Beef and Simmental bull-calves. Class of leather in all the studied groups exceeded the industry average (85.4% – first-class units). The results of physical and mechanical tests confirmed that the leather, produced from the hides of the bull-calves of the studied breeds, on the basic parameters complied with the requirements of the standard in the industry. Southern climate of Ukraine does not adversely affect the formation of skin of imported Hereford, Aberdeen Angus and Charolais bull-calves. The hides of beef bull-calves in all the age periods (even till 30 months) are the raw materials of sufficient quality and first-class leather can be made from it. Accelerating the development of specialized beef cattle-breeding in the steppe zone of Ukraine can reduce import of leather and thus save certain amount of currency funds.

The results of researches on the development of new mineral feed additives based on raw materials produced by Uralchem and the study of the eff ectiveness of their use in the rations of lactating cows have been presented in the article. The experiment has been carried out in the conditions of LLC “PF Barabinskoe” in the Dalmatovsky area in the Kurgan region where 3 groups of lactating cows of Black-and-White breed have been formed. Animals in the control group have been received the ration adopted in the farm, the 1st experimental group with the additive RusMA No. 1 at a dose of 150 g, the 2nd experimental group– with the additive RusMA No. 2 at the dose of 350 g. The use of experimental mineral additives in feeding lactating cows allowed us to increase their milk productivity and profi tability of production. At the same time, the best eff ectiveness was shown by the additive RusMA No. 2 at the dose of 350 g/head/day. The use of RusMA additives during the experiment period (105 days) allowed to increase the milk productivity of cows in the 1st experimental group by 6,03 % and in the 2nd experimental group by 8,24 %. Taking into account the fat content in milk, this diff erence was 6,31 and 8,53 %, respectively. The energy value of milk from cows of the experimental groups was higher compared to the control group by 2,45 and 1,76 %, respectively. According to the content of dry matter in milk, cows of the 2nd experimental group exceeded the control and 1st experimental group by 0,39 and 0,12 abs.%, respectively. The maximum milk fat content has been observed in the milk of cows of the 1st experimental group by 0,03 and 0,01 abs.% more than in the control and 2nd experimental groups, respectively. In terms of protein content, the cows of the 2nd experimental group signifi cantly exceeded the control group by 0,10 abs.% and the 1st experimental by 0,04 abs.%. The content of milk sugar in the 2nd experimental group was higher than in the control by 0,30 abs.% and compared to the 1st experimental by 0,11 %. Signifi cantly more calcium and phosphorus were contained in the milk of cows of the 2nd experimental group by 4,58 % (Р ≤ 0,001) and 2,86 % (Р ≤ 0,05), compared with the control group. The expenditures of feed in the EFU for the production of 1 kg of milk in animals of the 2nd experimental group was less by 5,13 % than in control cows and by 2,63 % compared to the 1st experimental group. The prime cost of 1 centner of milk was lower in the 2nd experimental group by 3,94 %, in the 1st experimental group by 2,65 % compared to the control group. The level of profi tability of milk production in the 2nd experimental group was higher by 9,0 and 1,0 abs.% in comparison with the control and 1st experimental groups, respectively.

Abstract Background Essential oil of Rosa × damascena Herrm. is one of the most valuable and important raw materials for the flavor and fragrance industry. The cultivation of this plant has ancient origins, and Kashan was one of the first mountainous regions of Iran dealing with the cultivation of R. × damascena. In this study, both chemical composition and antimicrobial activity of different rose essential oils obtained from five mountainous areas of Kashan region (Maragh, Qamsar, Sadeh, Javinan, and Kamoo) has been investigated along with the influence of the environmental conditions on these properties. Results Results showed that yield and chemical composition of essential oils obtained from Rosa × damascena were significantly affected by the collection area. In particular, the yield of oils varied from ~0.08 to ~0.132% and citronellol (36.70-9.18%), geraniol (12.82-0.47%), nonadecane (22.73-10.36%), heneicosane (31.7-11.43%), and 1-nonadecene (6.03-3.93%) have been detected as main compounds in all the plants collected, but at different concentrations depending on the collection area. The best fragrance and the highest yield were found in the oil from Kamoo area. Similarly to the chemical composition, the antimicrobial activity of the essential oils was affected by their origin, and essential oil obtained from plants collected from Kamoo area disclosed the highest antibacterial and antifungal efficacy. Its inhibition halos were 17.33±0.58 mm against Aspergillus brasiliensis, 15.67±0.58 mm against Staphylococcus aureus, and 12.33±0. 58 mm against Streptococcus pyogenes. Essential oils of R. damascena were also effective against Gram-negative Pseudomonas aeruginosa and they had a MIC value of 62.50 μg/mL irrespective of the collection area (except the oil from Javinan area). On the contrary, the highest antifungal power against Candida albicans yeast was reached using the essential oil obtained from plants collected in Javinan region (MIC and MBC ~62.50 μg/mL). Conclusions Overall results underline the influence of environmental conditions of the different areas of Kashan region, on the chemical composition of and antimicrobial activity of the essential oils of Rosa × damascena. In addition, results disclosed that Kamoo seemed to be the most suitable area for the competitive cultivation of R. × damascena to the intensive production of aromatic flower oil and natural antimicrobial essential oils.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.
