Full textCurrently, the agribusiness activities require, as all other areas, innovative solutions that empower the most different demands of business; the precision agriculture is a path that has been showing efficient decision-making. Nowadays, the application of unmanned aerial vehicle UAV - or also known as aircraft remotely piloted - ARP has been showing a growing insertion tool within this context and application. The farmer\'s decision making, be he small, medium or large, can be aided with the use of equipment and software that has become an usual practice both in the activities of agriculture as in others, that due to its easy application, low cost and great possibility of applications in the different activities of the agribusiness. Rotary wing vehicles are, in this context of use, tied to specific applications, an effective solution in different management cultures and activities in agribusiness. The results observed with the flights taken, with collections of images, as well as the mapping of cultures and rural properties have proven satisfactory throughout the research, both in the form of manual flight control mode of collection of data, another factor that enabled the research was the use of imaging applications and flight path, in this way, it was possible to accomplish the different objectives proposed in the research.

Full textEn el segle XVIII es constata un avanç de la producció vinícola, gràcies a l'estímul de l'augment de la població. No obstant això, aquesta disminueix a partir de 1830, quan l'economia insular sofreix una severa depressió. L'excedent vinícola generat ocasiona una forta caiguda dels preus. Així, quan el oídium assoli la illa a partir de 1852, s'experimentarà una arrencada massiva de vinyes.
Paral·lelament augmenta el pes de la ramaderia bovina, amb una importància creixent de la producció formatgera, i que, quan a la dècada de 1960 desaparegui el cultiu del blat, es convertirà en l'únic sector agrari de la illa. Tanmateix, i malgrat l'augment dels rendiments esdevingut a partir de 1950, la ramaderia presentarà una capacitat de generació de renda decreixent.
En este estudio se analiza la evolución del sector vitícola de Menorca durante los siglos XVIII, XIX y XX confrontándolo con la del sector ganadero.
En el siglo XVIII se constata un avance de la producción vinícola, gracias al estímulo del aumento de la población. Sin embargo, ésta disminuye a partir de 1830, cuando la economía insular sufre una severa depresión. El excedente vinícola generado ocasiona una fuerte caída de los precios. Así, cuando el oídium azote la isla a partir de 1852, se experimentará un arranque masivo de viñedo.
Paralelamente aumenta el peso de la ganadería bovina, con una importancia creciente de la producción quesera, y que, cuando en la década de 1960 desaparezca el cultivo del trigo, se convertirá en el único sector agrario de la isla, pero que, pese al aumento de los rendimientos acaecido a partir de 1950, presentará una capacidad de generación de renta decreciente.
This study examines the evolution of the vineyard in Minorca during the XVIII, XIX and XX centuries, and compares it with that of the livestock sector.
In the eighteenth century there is a breakthrough in wine production, thanks to the stimulus of increased population. However, it decreases from 1830, when the island economy suffers a severe depression. The wine surplus generated causes a sharp drop in prices. Thus, when the oidium plagued the island from 1852, it will experience a massive boot vineyard.
In parallel, the weight of cattle increases, with a growing importance of cheese production, and which, when in the 1960's the crop of wheat disappear, it will become the only agricultural sector of the island. However, and despite the rise in yields occurred after 1950, it will present a declining capacity of income generation.

Full textIn Late Antiquity, especially between the 5th and 6th centuries, Central Syria witnessed a strong expansion of sedentary settlements eastward, which coincided with a significant agricultural development of these new territories. As for other areas in Syria and Near-East at the same period, a waning climatic optimum seems to have allowed byzantine population to settle down in marginal areas which barely experienced hitherto sedentary occupation and farm nearly unbroken lands.Central Syria is made up of various landscapes, sometimes deeply nested, with contrasted agricultural potential. Settlements and agricultural exploitation are affected by an increasingly significant climatic and edaphic aridity eastward and southward. These conditions, which may locally improve thanks to ecological niches, enabled specific and often complementary substance strategies to develop.In a country whence cities are virtually absent, villages and a few market towns seem to be at the very root of the regional economy. Along with agglomerations, scattered habitats – namely farmsteads and monasteries –, more numerous under heavy bioclimatic constraints, would appear as independent and apparently prosperous economic players.Homogeneous geographic areas led to specific settlement patterns and different economic orientations. Food-producing agriculture remains the rule, but a local productive specialization may be noticed: mainly wheat production and incidentally plantations westward, olive-growing and maybe wine-growing as well in the north-west basaltic plateaus and presumably speculative livestock exploitation eastward and southward, probably mostly due to sedentary populations

Full textThe domesticated rabbit (Oryctolagus cuniculus) is today a common pet worldwide. Pet rabbits are highlighted as the third most popular pet in Sweden, after dogs and cats. Despite this, only a very small proportion of the overall research in the subject of health and welfare deals with rabbits. This study has examined the impact on the companion rabbit's welfare of rabbit owners with or without previous experience, disease picture, and rabbit owners' preferences - and whether these are factors that affect the companion rabbit's welfare in Sweden. The study was conducted as a survey, answered by 147 participants living in Sweden. The survey was published in the network service Facebook and found available during the period 23 April - 7 May, 2021. More than 50% of the participants lacked experience and knowledge about rabbits before acquiring their first rabbit. Over 37% kept their rabbits alone, and more than 21% housed their rabbits in cages. The need for veterinary care accounted for a total of almost half of the rabbits, and the rabbits kept indoors or free-running were most in need. There was a difference in the need for veterinary care in different breed categories, where the category small breeds was most represented. The number of rabbits suffering from various types of health-related problems varied, but diseases linked to breeding-related problems accounted for almost 1/3 of all diseases. The most common breed category to keep was dwarf breeds held by almost 60% of all participants, and the most common reason for choosing that particular breed category was its size. This study showed that there are factors in the rabbit owner's animal husbandry that can be linked to the companion rabbit's welfare in Sweden. Decisive parameters for this have been highlighted as the rabbit owner's experience and knowledge of rabbits, posture and housing, as well as the choice of breed category. Keywords: Oryctolagus cuniculus, companion rabbit, animal husbandry, animal welfare, animal breeding, animal ethics

The purpose of this study is to explore the impact of transfer pricing on the effective tax rate of listed farms, forestry, fishery and animal husbandry companies in mainland China.It is rare to find the literature on the effective tax rate of listed farms, forestry, fishery and animal husbandry companies in mainland China. The parent company of the foreign company or the triangle trade, using the information of the listed farms, agriculture, forestry, fishery and animal husbandry companies in mainland China, using the transfer The pricing is used as a method for corporate tax avoidance. The empirical results show that the transfer pricing has a negative relationship with the effective tax rate. For the overall business performance of the company, since the reform and opening up over the years, Taiwanese businessmen who have worked hard in China Using the tax laws promulgated by the State Administration of Taxation of the People's Republic of China to save taxes in a reasonable and legal manner without tax evasion, such as setting up an OBU company overseas through a tax haven, and then passing the domestic after-tax surplus through the relationship enterprise. The transaction, transfer to the tax-free area or the 10% reduction of income tax expenses in the free trade zone has reached the purpose of saving taxes. This profit model, commonly known as "triangular trade", is a widespread tax avoidance by Taiwanese businessmen in various ways in mainland China. But now, on March 17, 2017, China has officially issued the "Special Tax Investigation Adjustment and Mutual Negotiation Program". The Administrative Measures and (No. 6 Announcement or Administrative Measures) were implemented on May 1 as the target for a comprehensive review of the pricing of transfer pricing tax in mainland China. This study used a sample of mainland China companies from 2007 to 2016. The results showed that mainland Chinese companies did use transfer pricing to allow companies to achieve effective tax rates. This conclusion is consistent with previous scholars' experts and research papers and expectations. It shows that the transfer price has a negative relationship with the effective tax rate.

Having undergone the storm of food safety crisis, consumers are acting in an evolutionary way in the post era of food safety. It is worthy of investigation under the rapidly changing consuming style how consumers can be convinced that all the eggs produced by egg industry in Taiwan are good for health, and what kind of marketing strategies can be used to respond to this severe market. This thesis is based on a case study of a company to investigate the success key factors in related to its markeing and management strategies. This thesis employs semi-structured interviews and Kotler 6P theory to analyze the marketing strategy of this company. Finally, the key success factors of this company are concluded. This thesis concludes the analysis and gives its strategic suggestions as the following. The key success factors are the quality of the main commodity eggs has been recognized by the market, niche commodity organic fertilizer has great potential,upstream and downstream integration, with cost reduction, foundr’s vision is clear, and positioning and fulfilling social responsibilities. That results in an wider access to trade marketing and thus leads to an increasing amount of sales.

Animal husbandry is the longest way for people to produce food. Due to the increase in food required for the global population increase, the number of livestock farming and the density of stocking have also increased, and the situation of environmental pollution has gradually increased. In order to improve the environment of livestock farms and reduce air pollution, this paper uses temperature and humidity sensors and air quality sensors to sense the environment and air quality of livestock farms. By controlling fans, sprinkler systems, negative ion generators, and ozone generators, the goal of improving livestock environment and reducing air pollution is achieved. This study is based on the Arduino Uno R3 evaluation board. The DHT11 temperature and humidity sensor and the MQ-135 air quality sensor are used to sense the environmental status of the livestock farm. By controlling fans, sprinkler systems, negative ion generators and ozone generators, we can improve the environment and reduce pollution in livestock farms. By using ESP-01 WiFi module, the environmental monitoring data and the controller status can be uploaded to the cloud server. Users can observe the environmental monitoring data and the controller status of the livestock farm through the web browser of various smart devices. This study constructs an agricultural Internet of Things for animal husbandry, which can sense and improve the environment and pollution of livestock farms, and can observe the state of livestock farms through the smart device.

The compost of livestock excreta is a good organic material, and swine waste not only contains trace elements like copper and zinc to improve mechanical, biological and chemical qualities of soil, but also can save the cost of chemical fertilizer. It is the best treatment to recycle those swine waste as compost, but it may pollute soil and environment if the compost contains excess copper and zinc accumulating in soil. This study investigates the change of soil heavy metal effected by added swine waste compost in Kimen country, where has poor soil qualities and distributed unevenly rainfall. Sampling 11 farmland soils which added its own swine waste as fertilizer to analyze both soil quality, feed and wastes (included sludge and wastewater after solid-liquid separated).Sampling method was drawing one hectare as one unite and sampling soils of five spots with five meter range around the center of one unite, and mixing five samples to analysis. Analyzing results show that farmland soil samples’ saturated adsorption of copper and zinc were 45 mg/kg and 100 mg/kg, which were lower than the monitor value of crop farms (copper:120 mg/kg, zinc:260 mg/kg); maximum copper and zinc concentration of farmland wastes were 100 mg/kg and 200 mg/kg, which related to the copper and zinc contains within feeds, fit the tolerance standard of organic fertilizer (copper:100 mg/kg, zinc:800 mg/kg). Among these sampling farmlands, soil pH value were from 3.8 to 6.7 all higher than soil fertility quality pH 2.69 requested by Kimen country in 2002, which showed adding swine waste into soil can buffer soil pH value. Adding swine waste may also polluted soil with heavy metal, soils in this study were lightly polluted although the heavy metal contains lower than monitor value of crop farm.

In Pingtung and Yunlin, animal husbandry is developed and intensive, and irrigated farmland by livestock wastewater is gradually becoming the normality. Due to ingredient of animal feed containing copper and zinc, long-term irrigation may cause potential pollution to the soil, so this study for soil and irrigation ditches of the fields near the intensive irrigation and drainage areas of Pingtung (intensive irrigation and drainage areas)and Yunlin (irrigation), sampled the soil, sediment and irrigation water individually, and the basic characteristics of the soil were analyzed after irrigation, compared with the two different irrigation methods to the differences of soil properties, discussion on the effect of livestock wastewater to the soil quality. The results showed that the concentrations and variability of ECs, copper, zinc and CEC of Yunlin area were lower than Pingtung, which the TOC was in the appropriate range, due to Yunlin area have the fixed irrigation of livestock wastewater, the soil quality is not affected by the rainy and dry season easily, and the crop have short tillage is required to turn over to increase soil porosity in order to pollutants are diluting to the bottom soil. It’s worth mentioning the problem of ammonia nitrogen in the groundwater of Yunlin. Due to animal husbandry waste water of Pingtung area have no limits for irrigation requirement and area of land, most of the fruit trees in Pingtung and which dry farmland without plowed soils result in the pollutants relatively accumulated in the soil surface easily and the water dilution of the rainy and dry season had a great effect on soil quality. In the Pingtung area, copper and zinc of irrigation water were much lower than the irrigation water standard but which some of the soil was higher than the monitoring value, compared with water and soil samples contain the copper and zinc of the Pingtung area, found that copper and zinc deposit in the sediment along with the time and gravity, inferred for the long-term irrigation of livestock wastewater or application of chemical fertilizers contained both copper and zinc adsorbed and accumulated in the sediment. For intensive irrigation and drainage areas and irrigation from animal husbandry wastewater, Yunlin area have the fixed irrigation of livestock wastewater and the soil quality is not affected by the rainy and dry season easily, and the crop have short tillage is required to turn over to increase soil porosity result in pollutants are diluting to the bottom soil, which conforms to the soil quality standard and suitable environment for crop growth.

Full textBoth humans and dogs are integral in sheep production systems; however, which is more aversive to sheep, or indeed, whether either causes significant stress, has not been shown experimentally. The aim of this thesis was to examine some behavioural and physiological responses of domestic sheep to the presence of humans or dogs. An arena test was used to measure the relative aversion of sheep to the presence of a human or dog, as well as to elucidate differences in the responses of flocks at the University of Western Australia (UWA) which were putatively selected for differences in fearfulness. A Y maze preference test was used to 'ask' sheep whether they preferred a human shaking a rattle or a barking dog. In both tests, adrenocortical responses were measured concurrently to support the interpretation of behaviour. The presence of a human or dog in the arena elicited significantly more avoidance and vigilance behaviour and less exploration than did the presence of a control object. However, the dog elicited significantly more of this fear-related behaviour, and significantly larger adrenocortical responses than did the human. Sheep also expressed a clear preference for a human shaking a rattle over a barking dog in the Y maze test and exhibited larger adrenocortical responses to the dog than to the human in the Y maze facility. The UWA flocks differed in their expression of locomotor and vocal activity; MA sheep were more active/vocal than the other flocks, not only in the presence of the human but also with the box or dog. MA sheep expressed less avoidance and vigilance and more exploration than the other flocks in the presence of the human and exhibited significantly lower plasma cortisol concentrations than LA sheep after exposure to the human (10-min sample). However, there were no inter-flock differences in fear-related behaviour or adrenocortical responses when the flocks were presented with the box or dog. The results do not support the notion that the UWA flocks have been selected for differences in a consistent predisposition to react fearfully. The adrenocortical responses measured in these studies were only moderate in magnitude and duration, with peak plasma cortisol concentrations 2-3 times higher than pre-treatment values, and all concentrations returning to pre-treatment levels within one hour of the start of treatment. If these observations are confirmed in practical situations, the presence of humans and dogs during routine handling should cause little concern on the basis of animal welfare. However, limiting the presence of dogs in certain situations (e.g. before slaughter) may reduce stress in domestic sheep. Significant methodological developments in this research include the use of multivariate statistical techniques to analyze arena behaviour, the concurrent measurement of adrenocortical and behavioural responses in the arena and Y maze tests, and the explicit testing of the effects of individual lateral biases on choice behaviour in a Y maze test. Future studies should measure sheep stress responses to the presence of humans and dogs in practical situations.
