With the development of China’s industrialization, the reduction problem of grassland area caused by unglazed land occupation has become increasingly prominent. The driving factors of the decrease of forage land area gradually changed from the beginning of livestock overloading to the non-animal husbandry factors such as industrial occupation. On the basis of classification and summary of the related research results of the change of pasture grassland resources, this paper analyses the distribution characteristics and utilization status of grassland resources in China.

AbstractParabronema skrjabini is one of the most harmful nematodes to camels and is responsible for economic losses in animal husbandry industry. There is an urgent need for in-depth studies of potential vectors of the nematode due to its scant regarding information. As previous studies indicated that flies may be the vectors of P. skrjabini, we captured flies in the main camel-producing areas of Inner Mongolia. After autopsy of the specimens of two species of horn flies, we observed the morphology of the suspected nematode larvae found in them. Internal transcribed spacer ribosomal-DNA gene sequences were considered the best candidate to confirm the species of the larvae found. Our results showed that the homology compared with P. skrjabini was 99.5% in GenBank. Subsequently, we preliminarily identified two species of horn flies through morphological observation and then sequenced the mitochondrial-DNA-gene cytochrome oxidase subunit I obtained from two species of horn flies, with 100 and 99.2% similarity to sequences deposited in GenBank, respectively. Thus, we identified Haematobia titillans and Haematobia irritans and provided evidence for their potential role as vectors of parabronemosis. Our study provides reference for future research on the life history of the nematode and the vectors of parabronemosis.

Mongolia is a country with an approximate area of 1.5 million km2. Its population is 2.5 million, nearly 90% of whom are ethnically Mongolian. Khalkh Mongols form the largest subgroup (approximately 79% of the population); the next largest subgroup is the Kazakhs (5.3%), followed by smaller groups such as Tuvins, Uzbeks, Uighurs, Russian and Chinese. The population is young, with 35.9% under the age of 15 years. The official language is Mongolian. Just under half the population live in rural areas and around a fifth live a nomadic life. About 80% of the land area is suitable for agriculture, mostly for animal husbandry.

The Grassland Ecological Compensation Policy (abbreviated as GECP), which aims to realize the ecological protection by reducing the stock-carrying capacity of pastures and promote the transformation of pasture animal husbandry by improving the herders’ breeding methods, has been a major project in China’s grassland pastoral areas and grassland ecological construction. This study, thus, sought to measure the breeding efficiency of herders before and after the implementation of GECP. Moreover, the study also thought to analyze the effect and the effecting path of the implementation of GECP on the efficiency of herders’ livestock breeding. GECP enables herders to obtain financial subsidies while minimizing the utilization of grassland, which brings challenges and opportunities to herders’ traditional livestock production. This study used the two-stage data obtained from a randomly selected sample of 449 herders in the Inner Mongolia grassland area of China in 2018. Data envelopment analysis (DEA) and parallel mediating effect (PME) models were used to analyze the data. The results show that the general effect of GECP on the breeding efficiency of herders in the Inner Mongolia is positive (P < 0.01), and the change of breeding methods (direct effect) is the main influence path. Specifically, the grassland circulation behavior (P < 0.01) and the scale of breeding (P < 0.01) are part of the mediating effect. While the mediating effect of the breeding structure is not significant (P > 0.1). This study also shows that the non-agricultural and animal husbandry income of herders has a negative impact on the breeding efficiency (P < 0.01), and herders’ age and breeding scale have a positive effect on the breeding efficiency (P<0.01). This study has not only answered the question whether the GECP can improve the efficiency of husbandry, but also focused on the analysis of the impacting mechanism of policies on efficiency. It is of great significance to further improve GECP and the related supporting policies and promote the transformation of China’s grassland animal husbandry.

Abstract. Cultivated land resources are the basic production factors that carry human survival and economic development. Exploring the relationship between cultivated land change and economic development has become a hot issue for scholars.in this paper,The methods of regression analysis, land use elastic coefficient method, location entropy are used to empirically describe the relationship between cultivated land change and economic development.The results show: Since the 20th century, the change of cultivated land area has experienced three distinct stages of change, showing a process of recovery, decline, and steady evolution in Henan Province. The per capita cultivated land area is characterized by an upward trend, and the per capita cultivated land area is increasing year by year. In general, the intensive use of cultivated land in Henan Province is still not high, but the momentum of a sharp decline in cultivated land is basically controlled. The change of cultivated land area and economic development showed a four-time curve fitting relationship, which indicates that the path dependence of economic development on cultivated land occupation still exists, and cultivated land supports the rapid development of economy.The research results of the relationship between cultivated land change and economic development by using location entropy show that the spatial layout of the urban area is less than 0, and the regularity is not strong.The location where the location entropy is between 0–1 is mainly located in the central part of Henan Province;The cities with location entropy greater than 1 are mainly located in the eastern part of Henan.

A major part of the animal products are based on the grasslands, due to the fact that the grassland ecosystems can be found all over the globe. In places where economical and successful crop production cannot be realized, the grassland based animal husbandry can be an efficient way of food production. In addition these ecosystems have an important role in carbon sequestration, and with their rich flora – and the fauna connected to it – in conservation of biodiversity. The protection of nature, and the sustainable agriculture is getting more and more attention in the European Union, but looking at the consumers’ needs, the production of healthy food cannot be neglected either. Because of these facts, the effects of two specific composts - which are officially authorized in organic farming, in Agri-environment Schemes and Natura 2000 programs – on grass yields and sward compositions were investigated in a field trial. The investigation took place in Hungary, on a natural grassland based on solonetz soil. The first type of compost was a natural one (N) without any additional material and the other one was enriched in phosphorus (E). Both was produced by the research institute, made of sheep manure. Three rates of compost (10 t ha-1, 20 t ha-1,30 t ha-1) were tested on 3 m×10 m experimental plots. Every treatments had four replications and both type of compost had four-four control plots too, this way 32 experimental plots were included in the investigations. The yield of the pasture was harvested two-times (in May and in September) and before cutting the plots measurements on botanical compositions were made. Samples for laboratory analysis were also taken. Dry matter yield and crude protein content was measured in laboratory and with the received data the yield per unit area was calculated. Based on the research results we can say that the application of compost in any dose inflicts higher dry material and crude protein yield. The changes were partly due to some positive changes in sward composition, because of the better nutrient conditions. The research results indicate, that use of organic compost can be an efficient way to increase grass yields in a sustainable way.

The purpose of the article is to analyze the current state of the meat market in Ukraine, to identify trends in its development. Research methods. The following methods have been used generally accepted methods and techniques: a set of scientific methods of abstract and logical method (induction and deduction, analysis and synthesis, analogy and comparison, formalization) for develop theoretical positions and analyze the situation in the meat market; statistical when assessing the meat market; tabular for visual representation of the research results; graphic for identify and illustrate trends of the research economic phenomena. Research results. The meat market is an important component of the food market of the country, on the stability of which the living standards of the population and the food security of the country largely depend, has been generalized. Meat and meat products are among the most important foods. It has been found that the meat market operates in rather difficult economic conditions. Meat producers increase production volumes with the decline of certain branches of animal husbandry In the livestock industry of Ukraine there are transformational processes that cause changes in the meat market structure. The meat market structure is considered and the peculiarities of its functioning are revealed. Poultry meat has been found to have a monopoly on the meat market. The increase in poultry meat production is primarily due to the growing demand from the population and the food industry. The basis of the "meat diet" is poultry meat, as the most available type of meat has been determined. Scientific novelty. Production of poultry meat in Ukraine is the most profitable has been specified. The rapid return on investment in poultry production has led to increased investment in the industry, the construction of modern large poultry farms and the creation of powerful vertically integrated companies. Pork production has stabilized somewhat. However, African swine fever causes significant damage. Raising cattle remains a non-profit business. The trend of cattle slaughter continues in Ukraine,. At the same time, the main producers of cattle meat are households. Analytical assessments and determinations of factors influencing meat production and further development of the meat market have been further developed. Practical significance. Analytical materials of the article have been based on relevant official statistics, which can be can be used for addressing development of the meat market. Research results can be useful for all meat market participa nts. Tabl.: 1. Figs.: 1. Refs.: 19.

Islamic boarding school or <em>pondok pesantren</em> is one of the islamic educational institutions that grow fastly in Indonesia. Some efforts that can be done to improve the quality of <em>pondok pesantren</em> can be done with conservation activities that is through land optimalization. Activity of land optimalization is a strategic effort that can be done in <em>pesantren</em> environment in order to maintain the existing land resources in pesantren supported by large enough land and enough human resources. <em>Pesantren</em> which do the activities of land optimalization continuously referred to conservation islamic boarding school or <em>pesantren konservasi</em>. The program of <em>pesantren konservas</em>i include activities of land optimalization conducted in the field of feed crops to develop the potential the sector of animal husbandry. Focus on the goal to be achieved is to support the better feed for the better food too. This study was conducted in March–May 2017, at Pondok Pesantren Darul Fallah, Ciampea, Bogor. The methods through several steps include the identification of islamic boarding school, get contacts of foundation management, observation of islamic boarding school application and assosiation. Beside that, practical activities in <em>pesantren konservasi</em> include the clearing of land area, crop selection, planting, and mentoring. In addition to creating an islamic boarding school environment-based, <em>pesantren konservasi</em> also helps to develop human resources that can compete in science and economics.
