Irrigation, income and poverty alleviation: an assessment study of kampe irrigation dam in Ejiba (Kogi state, Nigeria)

Irrigation, income and poverty alleviation: an assessment study of kampe irrigation dam in Ejiba (Kogi state, Nigeria)

Opeyemi Gbenga, Babatunde Raphael Olarenwaju

Статья научная

Irrigation has been suggested to be a central key part in curbing food scarcity and alleviating poverty not only in Nigeria but also in many other developing countries. The continued dependence on rainfall in agriculture has proved incapable of sustaining the population increase. The study was conducted to assess the role of Kampe irrigation dam on farm household’s income-poverty status in Kogi State, Nigeria. A two stage sampling technique was utilized for the study. Samples were drawn from irrigation beneficiaries and non-beneficiaries within the project community. A total of 140 respondents were interviewed using structured questionnaire. Also, the study used the Foster-Greer-Thorbecke (FGT) model which was used to examine the incidence, gap and severity of poverty among the sampled respondents. Logit regression model was used to identify the factors contributing to poverty state in the study area. The poverty incidence was 41% and 57% for irrigation beneficiaries and non-beneficiaries respectively. Poverty gap i.e aggregate expenditure shortfall was 6% and 21% for irrigation beneficiaries and non-beneficiaries respectively. However, poverty severity was much higher among irrigation beneficiaries (28%) and 23% for irrigation non-beneficiaries. Farm household size, total annual farm income and total input cost all contributed to the poverty situation in the study area. The study agree that irrigation dam project would contribute to reducing income-poverty of irrigation farm households, from the result, the study also, based on the key research findings, this study provides recommendations on policy and interventions for making irrigated agriculture effective tool for poverty reduction program.

Mathematical simulation of microclimate of sub-surfaced in the ground potato storehouses

Kondrashov V.I., Prusakov G.M., Moiseenko A.M.

Статья научная

The highest significance in the safekeeping of the biological production has the heat-moister regime in the storehouses and inside of a stored agricultural produce. Existing storage technologies demand certain adjustment in each case, which can be significantly simplified with the computer simulation. The adequate model with realistic conditions can be provided with the complete mathematical description and all basic factors taken into an account. The purpose of this work is the development of the methods of the heat-technical calculation and computer simulation of vegetable storehouses microclimate by solving the conjugate non-stationary heat and moister exchange tasks. The full mathematical model of a heat-exchange is based on the conjugate non-stationary heat-moister exchange task for the whole system construction-equipment-bulk in their heat interconnection, but not for each component separately taking part in the heat-exchange. As a generic math model we consider the heat-moister condition of a semi-sub-surfaced in the ground storehouses, because in this case it's necessary to take into account the heat interaction not only with air surroundings, but also with the ground, unlike above ground surface storehouses as a particular version of common model. Developed the finite-difference method of calculations which have sufficient enough high-speed and accuracy for engineer practice. These methods allow in short time calculate the temperature and moisture in the storehouses. Software package POSOH (Kondrashov, Kondraschov, Kokin, Tyukov, 2003) was designed for computer modeling of these processes. Examples of the simulation for selection of most appropriate construction and technology parameters for reduction of depreciation of agricultural production during storage are provided. The heat-resistant properties of above surface and semi-sub-surfaced storehouses were compared.

Milk production on a modern dairy farm

Milk production on a modern dairy farm

Shilov A.I., Lyashuk R.N.

Статья научная

Based on statistical, theoretical and empirical research methods we present the analysis of milk production on modern robotic farms. We have evaluated the production potential of the dairy industry. The issues of feeding, milking, housing, breeding under the conditions of using robotic milkers without the use of human resources are also highlighted. According to domestic researchers, an investment in a robot gives an additional annual revenue of about 1 million rubles. With such revenues, the payback period of the milking robot is from 3 to 5 years. The fundamental element of economic efficiency, of course, is the high milk production of cows, when the yield should be 8-10 thousand kg of milk per cow per year. The efficiency of the milking robot increases significantly when the accompanying innovative production elements are introduced on the farm. These include innovations in feeding, housing, breeding, reproduction of animals, which allow achieving the declared productivity of robots and their payback period. At the same time, robotic milking puts more demands on the cows themselves. For example, the robot does not work with cows with abnormal udders (teats close together, short or elongated, etc.) or animals that do not want to enter the milking stall. As a rule, culling of such animals is about 10-12%. In this case the above mentioned selection of milking herd gains special significance, because cows not only of the same breed, but also of the same type, close in their biological and technological indicators, belonging to several homogeneous families will be more preferable in their selection to milking stalls. It depends on how correctly the initial path for organizing a new economic approach will be determined, first of all, its other management both in terms of selection, in terms of reproduction, and in terms of working with the herd as a whole.

Mineral metabolism, taking place in different phases of postnatal ontogenesis in standard minks hair covering

Balakirev А.N., Staroverova I.N., Maksimov V.I.

Статья научная

It is proved that the content of mineral elements in standard mink organism can be detected by mineral composition of their hair covering. Considerable changes of mineral elements concentrations in mink hair covering are happening with age. This must be taken in account for forming balanced feed rations. To study mineral metabolism taking place in different postnatal ontogenesis phases in hair covering of standard minks, and also for unbiased assessment of the character of interconnection between the concentration of macro and microelement in hair covering, in blood with its concentration in feed rations biological absorption factor was calculated. The obtained results testify that mineral compositions of the rations applied in the farm and mineral compositions of hair covering of standard minks are interconnected and change seasonably and with aging. Thus, hair covering mineral composition, apparently, can be used as test for balanceness by mineral rations elements for every age of standard minks.

Статья научная

Morphological and biochemical blood indices in high-yielding cows of Holstein breed with extremity diseases of various etiologies under oxidative stress in industrial dairy cattle management technology were analyzed in article. Over the last 30 years diseases of the distal part of cows’ extremities are the most important problem of livestock, because they cause significant economic damage to the farms at the expense of disposal of a large number of sick animals (50%), first of all, the most productive. Therefore, the dairy cattle management in industrial livestock management requires knowledge of the main causes that determine the hoof diseases, as well as early diagnosis for timely prevention of various hoof diseases. In practice, as a rule, the extremity diseases in the results of the combined effect of several factors are appeared. All these factors prove that metabolic disorders play an important role in pathogenesis hoof diseases of different etiology in cows. We believe that identification of pathogenic mechanisms at the level of metabolic processes for the development of methods for the prevention and correction of violations is perspective. Significant value can have profound biochemical studies for organization and conducting a comprehensive treatment, and it is necessary to detect preclinical disease development.
