Because of the feeding technology innovation, accelerated transport and communication facilities breeds of high performance breeds replaced local autochone breeds worldwide. These latter species however have an important role in gene conservation. Hungarian cold-blooded horse breeding stock are lacking pedigree, the actual founder breed mares are not known. For this reason, it is an major priority defining the genetic backround of the existing flock, for that breeding could operate with purposeful using of origin maternal founders. In the present study 195 cold-blooded Hungarian mares tail and mane sample were analized. Our analysis was carried out between 15531–15752 base pairs in mithocrondial DNA D-loop region, which reported a total of 222 base pairs. Fourtyone polymorphic sites were determined, which resulted in 39 haplotypes (h=39). The average pairwise differences were k=6.825. High haplotype and nucleotide diversity values were observed (Hd=0.968±0.003, π=0.026±0.003). Based on the previously defined variable positions of haplotypes defined by Jansen et al (2002), we groupped our haplotypes into haplogroups. 23 percent of the studied population (45 mares) belonged to haplogroup F1. Nearly 97% of the analyzed population was classified into one of eight  haplogroups defined by Jansen.et al. (2002). This study gives genetic information nearly 25% of the Hungarian population. Another possibility would be patterning more mares or involving more genetic marker in the study which will assuming the possibility of a more comprehensive analysis.

As the income of urban and rural residents has increased in recent decades in China, dairy products have become an important part of the Chinese diet. Therefore, keeping up with the growing demand for feed grain for dairy cows is a critical issue of feed grain security. Utilizing traditional statistical and spatial statistical methods, this study analyzes the spatio-temporal dynamics of dairy cow feed grain (DCFG) demand on the provincial, regional, and national levels across China from 1990 to 2016. Additionally, this paper explores the impacts of various factors on the spatio-temporal dynamics of DCFG demand using the Geo-Detector method. The results demonstrate that: (1) the temporal dynamics of DCFG demand can be divided into three stages of slow growth, rapid growth, and high-level stability, and the relative level of DCFG demand in the whole animal husbandry tends to decline; (2) at the regional and national levels, the spatial concentration of high DCFG demand has intensified; in particular, North China was the region where the largest demand for DCFG was localized and was increasing at the highest rate; (3) based on the hot spot analysis of provincial DCFG demand, the high and low demand provinces of DCFG have sharp characteristic contrast from north to south China; (4) the spatio-temporal dynamics of DCFG demand in China were essentially co-affected by the four groups of factors (e.g., resource endowment, feeding scale, feeding technology, and market environment), of which resource endowment and feeding scale were the dominant factors. Therefore, in the future, dairy cow feeding in China should promote grain-saving feeding technology, improve the utilization of forage, expand large-scale feeding, and create a good market environment to ensure the reasonable development and sustainability of DCFG demand.

The production of synthetic or substitute natural gas (SNG) from coal is a process of interest in Colombia where the reserves-to-production ratio (R/P) for natural gas is expected to be between 7 and 10 years, while the R/P for coal is forecasted to be around 90 years. In this work, the process to produce SNG by means of coal-entrained flow gasifiers is modeled under thermochemical equilibrium with the Gibbs free energy approach. The model was developed using a complete and comprehensive Aspen Plus model. Two typical technologies used in entrained flow gasifiers such as coal dry and coal slurry are modeled and simulated. Emphasis is put on interactions between the fuel feeding technology and selected energy output parameters of coal-SNG process, that is, energy efficiencies, power, and SNG quality. It was found that coal rank does not significantly affect energy indicators such as cold gas, process, and global efficiencies. However, feeding technology clearly has an effect on the process due to the gasifying agent. Simulations results are compared against available technical data with good accuracy. Thus, the proposed model is considered as a versatile and useful computational tool to study and optimize the coal to SNG process.

Жизненно важными микроэлементами для жвачных животных являются медь, цинк, марганец, железо, кобальт, йод, селен. Микроэлементы, в которых атом металла соединён и защищён белковыми молекулами, улучшают воспроизводительные качества самок за счёт повышения оплодотворяемости, уменьшения эмбриональной смертности, улучшения состояния мочеполовой системы или повышения интенсивности функционирования яичников. Поэтому в настоящее время актуальными являются разработка и внедрение в технологию кормления сельскохозяйственных животных наиболее эффективных препаратов с необходимыми биологически активными веществами. На основании проведённого исследования дано практическое обоснование использования в технологии кормления тёлок отечественной кормовой биодобавки на основе гидролизата соевого белка, витаминов и микроэлементов. Установлено её положительное действие на некоторые функции органов и систем животных. Экспериментально доказана эффективность её применения для оптимизации обменных процессов и повышения воспроизводительных функций тёлок. Так, биохимическим исследованием образцов крови подопытных животных установлено, что количество кальция и фосфора в крови у тёлок опытной группы по сравнению с контролем было достоверно выше на 2,35 и 2,9% соответственно. Эритропоэтическая фракция была более выражена у молодняка опытной группы. У тёлок опытной группы время от начала скармливания препарата до первой выраженной охоты и осеменения, по сравнению с контрольными животными, сократилось на 16%, а период от начала скармливания препарата до плодотворного осеменения – на 25,7%. Количество тёлок, пришедших в охоту и осеменённых в первый месяц, в опытной группе по сравнению с контрольной было на 43% больше. Оплодотворяемость тёлок опытной группы за учётный период составила 95%, что на 20% больше, чем у животных контрольной группы. Включение в рацион тёлок биодобавки в дозе 100 мл/гол. позволило получить дополнительно на 8,5% больше валового прироста живой массы по отношению к их аналогам. The vital trace nutrients for ruminants are copper, zinc, manganese, iron, cobalt, iodine, selenium. Microelements in which a metal atom is jointed and protected by protein molecules improve the reproductive qualities of females by increasing fertility, reducing embryonic mortality, improving the state of the genito-urinary system or increasing the intensity of ovarian functioning. Therefore the development and implementation of the most effective preparations with the necessary biologically active substances in the technology of feeding farm animals is currently relevant. On the ground of conducted research a practical substantiation of the use of domestic food supplement based on the hydrolyzate of soy protein, vitamins and trace nutrients in the feeding technology of heifers is given. Its positive effect on some functions of animal organs and systems has been established. The effectiveness of its application to optimize metabolic processes and increase the reproductive functions of heifers has been experimentally proven. Thus a biochemical blood samples analysis of experimental animals found that the amount of calcium and phosphorus in the blood of the heifers of the experimental group compared with the control was significantly higher by 2.35 and 2.9% respectively. The erythropoietic fraction was more defined in the young experimental group. In heifers of the experimental group the time from the beginning of feeding the drug to the first defined heat and insemination compared with control animals decreased by 16% and the period from the beginning of feeding the drug to prolific insemination – by 25.7%. The number of heifers that came to the heat and inseminated in the first month in the experimental group was 43% higher than the control group. The impregnation capacity of the heifers of the experimental group during the record period was 95% which is 20% more than in animals of the control group. Inclusion in the diet of heifers bioadditive at a dose of 100 ml / goal allowed obtaining additionally 8.5% more the gross body weight gain relative to their analogs.

One of the important parts of the technology of industrial milk production is the organization of the technology of feeding dairy cows, as in the cost of milk feeding costs reach 70%. To determine the effectiveness of the introduction of new approaches to the organization of feeding dairy cows, it is necessary to conduct a more detailed analysis – not only to determine the impact on dairy productivity, but also to take into account the economic component. Obtaining high milk yields is impossible due to unbalanced rations, poor quality feed and imperfect feed preparation technology. The use in practice of new approaches in balancing feeding rations allows to achieve the tasks at lower cost. The elements of feeding technology of dairy cows were introduced and the efficiency of using high-energy protein supplement with protected protein TEP-mix on two groups of dairy cows with a productivity of 15–20 kg per day was determined. The introduction of the proposed supplement to the diet provided an increase in the content of undigested protein in the rumen from 24.0 % to 34.0 % in the diet. This allowed not only to increase the milk productivity of cows, but also to improve the quality of milk. It was found that with the introduction of supplements in cows of the experimental group, in the rations of which used TEP-mix, the daily milk yield of cows increased by an average of 3.68 kg (from 12.0 to 15.68 kg), and in terms on the basic fat content – by 5.45 kg (from 13.24 to 18.68 kg), the fat content – by 0.30 abs. % (from 3.75 to 4.05 %), protein – by 0, 27 abs. % (from 2.95 to 3.22). At the same time, the average daily income per 1 cow in the sale of basic fat milk increased by UAH 41.65. (from UAH 26.46 to UAH 68.11), and the profit per 1 kg of milk of basic fat content – by UAH 1.65. (from UAH 2.00 to UAH 3.65). Based on multicriteria analysis, it was found that when using different approaches to the organization of feeding technology for dairy cows, the one that uses the additive TEP-mix with protected protein is more profitable.
