The results of the study of the infl uence of the age of slaughter of sheep at 6 and 8 months are presented. on the economic effi ciency of lamb production. When rearing and feeding rams up to 8 months of age, the feed costs per 1 kg of gain were 6.54 ECU and 746 g of digestible protein compared to 5.81 ECU and 640 g of digestible protein in rams grown up to 6 months of age. The level of profi tability of lamb production in animals sold at 6 months was 41.9%, and in sheep sold at 8 months of age-14.1%, which is 27.8% lower

В работе рассмотрено формирование групп коров на кормление по фазам лактации. Рассмотрены основные причины замены пропиленгликоля глицерином. Для обоснования исключения из рационов дойных коров сена приведен расчет потерь питательных веществ при разных способах консервирования люцерны, отмечено, что при заготовке сена потери протеина составляют 34,71, неструктурных углеводов 36,36 относительно зелёной массы, в результате энергетическая питательность снижается на 22,48. При заготовке сенажа процент потерь значительно меньше по сравнению с сеном. Анализ структуры корма посредством пенсильванской сортирующей системы показал соответствие содержания частичек корма при просеве на сите с разным диаметром ячеек нормативным требованиям. Применение адсорбента микотоксинов SaproSORB показало, что выход молока на один килограмм сухого вещества рациона увеличился на 6,74, себестоимость 1 кг молока с применением Сапросорба снижается на 0,16 рубля. При учёте потребления сухого вещества на одну голову в сутки в условиях жары отмечено увеличение поедаемости корма при сокращении внесения воды (более сухие рационы СВ 55 против СВ 50), увеличение молочной продуктивности. Сравнение химического состава сенажа без использования и с использованием консерванта Веst-Sil показало снижение доли лигнина на 17,2, увеличение легкоусвояемых углеводов на 21,6, чистой энергиии лактации на 7,2. Контроль работы корн-крекера комбайна и крупность резки кукурузы на силос производится посредством специального набора сит по отработанной методике. Экономический расчёт эффективности использования соевого, подсолнечного шротов и рекомендуемого использования зерна экструдированной сои собственного производства даёт экономию затрат корма на 1 кг молока 0,94 рубля, за счет снижения стоимости рационов. Контроль полноценности кормления коров и корректировка кормления производится как с учётом зоотехнических, так и биохимических показателей.The paper considers the formation of groups of cows for feeding by lactation phases. The main reasons for the replacement of propylene glycol with glycerin are considered. To justify the absence of hay dairy cows in the diets, the calculation of nutrient losses is given for different methods of preserving alfalfa, it is noted that protein loss is 34.71, non-structural carbohydrates 36.36 relative to the green mass when hay is harvested, as a result, energy nutrition is reduced by 22, 48 When harvesting haylage, the percentage of losses is much less relative to hay. An assessment of the analysis of the feed structure using the means of the Pencil sorting system showed that the content of feed particles during screening on a sieve with different cell diameters is in compliance with regulatory requirements. The use of SaproSORB mycotoxin adsorbent showed that the yield of milk per 1 kilogram of dry matter of the diet increased by 6.74, the cost of 1 kg of milk using Saprosorb reduced by 0.16 rubles. When taking into account the consumption of dry matter per 1 head per day in hot conditions, an increase in feed intake was noted with a decrease in water intake (more dry diets of SV 55 versus SV 50), an increase in milk productivity. Comparison of the chemical composition of silage without using and using the West-Sil preservative showed a decrease in the lignin fraction by 17.2, an increase in easily digestible carbohydrates by 21.6, and net energy and lactation by 7.2. The control of the work of the combine cracker and the size of the corn cutting into silage is carried out by means of a special set of sieves according to the well-established methodology. An economic calculation of the effi ciency of using soybean and sunfl ower meal and the recommended use of extruded soybean grain of our own production saves feed costs per 1 kg of milk 0.94 rubles, due to a decrease in the cost of rations. Monitoring the usefulness of feeding cows and adjusting feeding is carried out taking into account zootechnical and biochemical parameters

This article presents a study of the effectiveness of concentrated non-hydrolyzed feed protein granules (CNHPG) on the productivity dynamics and the quality final prod-ucts when included in the diets of suckling pigs and weaned piglets. Concentrated non-hydrolyzed feed protein granules represent a new type of soy protein concentrate free from antibiotics, hormonal remedies and GMOs. This feed supplement can be included either individually to the basic ration or into the composition of mixed feeds as the main highly digestible protein source with the original amino acid composition. The results of the research showed that CNHPG contribute to an increase in piglets average daily gain of 2.0-2.7%, reduce feed costs for obtaining a unit of production by 0.1-0.3 kg, as well as an additional gross gain in body weight from 8.2% to 14.6%

In comparative aspect growth and development, reproductive ability of heifers of Hereford breed at keeping in different rooms at different types of feeding are reflected. Heifers of two experimental groups (2nd and 3rd) in the stable period of maintenance in lightweight premises from birth to 18 months of age on a diet with 15–25 % concentrates, feed costs 2633,3 and 2611,5 K. units (3094,7 and 3019,0 EKE), digestible protein-295,2 and 293,5 kg. it was Revealed that by one and a half years of age, the live weight of heifers of 1–3 groups was 352,20±10,58; 373,70±13,28; 389,30±12,18 kg, which is provided by obtaining an average daily increase of 548–584 g against 475 g in the control group 1 (15,4 and 22,9 %). Economic maturity experienced heifers reached 17–18 months of age, which is 1.5–2 months before the heifers of the control group. In addition, the use of concentrates contributed to the formation of more pronounced meat forms in animals, which distinguish them from their peers of the control group in terms of indices of height, pelvis, downness, bony, broad-bodied. The study of the reproductive function of animals showed that the age of the established sexual cycle of heifers of the experimental groups came 21.4 and 20.6 days earlier than the peers of the control group. The age of fruitful insemination of heifers of the experimental groups is 23.7–40.0 days more than that of the control group peers.

Aim. A detailed analysis of the egg production and economic effi ciency of using a new dual-purpose hybrid in a comparative aspect with the original forms. Methods. Standard zootechnical methods of estimating body weight, egg production and its intensity, egg weight, feed costs and livability of adult hybrid and purebred hens were used. The effects of heterosis on the main utility indicators and the European profi t ratio IOFC (Income Over Feed Cost), which displays the difference between the revenue from one layer and the cost of consumed food, was estimated. Results. Almost all studied indicators demonstrated the advantage of the hybrid over the original forms. The phenomenon of heterosis was observed in most studied indices – 5.7 % by precocity, 3– 7 % by mass of eggs, 12–14 % by egg production. Early puberty (on 2–16 days), more intensive build-up of egg production (by 3.3–4.2 %), improvement of its medium intensity by 4.6–9.8 % provided by hybrid laying hens per year of life which were 9–20 eggs superior than the origin forms. Due to the high productivity and low feed consumption per 10 eggs (2.1 kg versus 2.8 kg for the paternal form), the profi t ratio IOFC was also 28.7– 29.1 % higher for a hybrid. This indicates the expediency of using layers of a new hybrid combination for the production of food eggs in farming and household farms. Conclusions. The obtained zootechnical and eco- nomic indicators demonstrate the expediency of using layers of a new hybrid combination for the production of food eggs in farming and household farms.

The ʿUthmānic way of writing (al-rasm al-ʿUthmānī) is a science that specialises in the writing of Qur'anic words in accordance with a specific ‘pattern’. It follows the writing style of the Companions at the time of the third caliph, ʿUthmān b. ʿAffān, and was attributed to ʿUthmān on the basis that he was the one who ordered the collection and copying of the Qur'an into the actual muṣḥaf. This article aims to expound on the two fundamental functions of al-rasm al-ʿUthmānī: that of paying regard to the ‘correct’ pronunciation of the words in the muṣḥaf, and the pursuit of the preclusion of ambiguity which may arise in the mind of the reader and his auditor. There is a further practical aim for this study: to show the connection between modern orthography and the ʿUthmānic rasm in order that we, nowadays, are thereby able to overcome the problems faced by calligraphers and writers of the past in their different ages and cultures.
