Abstract. Goats play a variety of roles all around the globe due to their capability to acclimatize different environmental conditions quite quickly since they have been regarded as one of the first sets of animals domesticated by the human. Even though domestic goats harbor precious genetic materials, research funding among developing countries is a major drawback for thorough study on them. Therefore, microsatellite markers seem to be affordable and informative. Genotypic data from different goat breeds across five countries (Nigeria, South Africa, Pakistan, France and Spain) was generated using eleven microsatellite markers for a comparative study in order to evaluate the usefulness of the available data for genetic characterization and identify the shortcomings of meta-analyses for combined data. The mean number of alleles (MNA) per population range from 6.44±2.83 alleles for Spanish to 10.25±0.96 for Pakistani goats, with an overall mean of 13.55±7.28. Observed heterozygosity (Ho) ranges from 0.61±0.02 to 0.83±0.01 for Spanish goats and Pakistani goats, respectively with an overall mean of 0.65. Ho of the markers used ranged from 0.569 (INRA5) to 0.793 (MM12). Highest and least polymorphic information content (PIC) was observed in loci MM12 (0.925) and MAF209 (0.489), respectively. All the populations showed significant change from Hardy-Weinberg equilibrium (P>0.05) indicating a low level of inbreeding. The genetic distance of each country’s goat populations ranged from 0.151 to 4.245. The highest genetic distance (4.245) was observed between Spanish and Pakistani goats while the lowest were observed between Spanish and French goats. Spanish and French goats are from a common ancestor while South African, Nigerian and Pakistani goats came from another ancestor or cluster. A lot of genetic admixture in the Nigerian ecotypes has been observed whereas France and Saudi Arabian breeds have been subjected to high amount of selection pressure.

Abstract. Many factors such as inadequate capital, poor infrastructure, poor price information could bring about distortion in the structure and performance of the market process resulting to the reduction in profit margin of marketers and a disincentive to present and prospective marketers of paddy rice. This study was conducted to analyze the structure and performance of paddy rice marketing in Adamawa State, Nigeria. The specific objectives were to examine the structure of rice market and to evaluate the performance of the market participants in the study area. Data were collected from 204 rice marketers using multi stage sampling technique. Herfindahl-Hirschman Index (HHI) was used to determine structure of the market, while Marketing Efficiency measure was applied in analyzing the market performance of the market participants. The HHI pooled results for year 2013, 2014 and 2015 revealed that paddy rice marketing in Adamawa State has a highly competitive market structure (11.38 and 71) with low (42% and 24%) marketing performance for retailers and wholesalers, respectively. To improve the performance of market participants, it is recommended that government should open up and rehabilitate the road network in the hinterlands to facilitate easy evacuation of agricultural inputs and commodities in and out of the market. Financial support and formation of unions would enable the marketers benefit from scale operation and enroll for training on entrepreneurship.

Abstract. The aim of the present study was to investigate the chemical composition, technological traits and incidence of boar taint of meat from entire male pigs from two of the commonest breeds reared in Bulgaria: Landrace and Danube White. Fifty meat samples from entire male pigs (22 Landrace and 28 Danube White) fattened to average live weight of 90 kg were investigated. The chemical composition of Landrace pig meat was characterised with insignificantly lower fat and mineral content compared to Danube White meat. There were no significant differences between both breeds as technological properties of meat (pH, water holding capacity, and cooking loss) were concerned. The breed had a statistically significant effect on meat marbling (р<0.001). Landrace meat exhibited insignificantly higher incidence of the unpleasant boar taint as compared to Danube White meat (27.27% and 25.00%, respectively).

Abstract. The study examined the profit potentials of fish farming in Mubi, Adamawa State, Nigeria. Data for the study were obtained from 70 respondents through snow-ball sampling technique between April and May 2015. The results revealed 81.43% of the respondents were youth within the age range of 20-40 years, with majority (74.29%) of them being males. About 74.3% had household members, which range from 1-5, more so, 54.3% had one form of formal education or the other. Most of the respondents also (54.30) were civil servants. Analysis of cost and returns from the fish farms unveiled a net farm profit of $407.37 (₦150 879.22) per cycle, with a benefit cost ratio of 2.03, which implies that a dollar is gained as a profit for every one dollar invested in the farming business in the study area. High cost of fingerlings (25.35%) and inadequate information on fish farming practices (15.02%) were among the major problems militating against fish farming in the area. The study recommended the supply of credit facilities to the respondents as well as extension services delivery through government and non-government organisations to improve on the farmers’ output.

Abstract. In the nature, difficulties with distinguishing of closely related species like Stone marten (Martes foina) and Pine marten (Martes martes) appear. Based on 280 photos a non-invasive method for determining the Stone marten and the Pine marten by camera trapping was performed. Sloping trees (similar to Leaning-Pole or Running-Pole) were used as a route for animals to pass with a purpose to be photographed. Honey and distal parts of bird wings were used as a lure. The camera was set to capture the climbing animal from the side. The coat coloration and scent marking patterns – proper species indicators – were clearly visible on daily photos. The night photos showed the differences in body proportion but not these in throat patch coloration. Profile photographing also allowed an individual determination based on throat patch shape and area.

Abstract. The purpose of the present study was to make wastewater characterization by physico-chemical parameters from two wastewater treatment plants (WWTPs) – Municipal WWTP (MWWTP) and Poultry meat processing enterprise WWTP (PMPEWWTP). The investigation was carried out during 2016 and 11 wastewater parameters (ToC, pH, EC, SS, COD, BOD and total forms of N, P, K, Na and chlorides content) were controlled in 4 monitoring points (MPs) at both WWTPs: MP-1 – inlet of WWTP, MP-2 – after section of biological treatment, MP-3 – outlet of vertical precipitators and MP-4 – outlet of WWTP. Wastewater samples were collected every two months from each MP and were analyzed by validated Bulgarian State and ISO standards. The following were recorded: a) the value limit variation at the surveyed parameters and their characteristics by monitoring points in both treatment plants; b) that both TPs demonstrated high removal efficiency (81.6-98.6%) in regard to SS, COD, BOD5, Total N and Total P, and very low removal efficiency in regard to Total K (2.2-12.5%); c) that the final effluents from both TPs meet the ecological requirements for discharge in the receiving water bodies (Bedecka River and Azmaka River, respectively) for the parameters SS, COD, BOD5 and TN and deviate from them by phosphorus content that exceeds the permitted limit; d) that in MWWTP there are 25 correlations (15 positive and 10 negative) between monitored WW parameters and in PMPEWWTP – 28 correlations (19 positive and 9 negative), respectively; e) that there are different trends in the changes of the controlled physicochemical parameters by monitoring points and by months in both WWTPs determined on the basis of a regression model – a polynomial of degree II; f) that Na, Cl, COD and BOD5 WW content correlates very well with some other parameters, which allowed the development of linear regression models to determine their concentrations.

Abstract. In conditions of growing tomatoes in the open field the effect of bioorganic fertilizers and growth regulators have been studied based on humic acids Nagro and Stimix on the main growth indicators, yield and immune response of plant in tomatoes for medium early production of the variety Milyana. It has been found that seed treatment and seedlings with the bioorganic products Nagro and Stimix improve the biometric indicators of seedlings and plants during vegetation and accelerate the process of flowering of tomato phenophases. Fertilization with those bioorganic fertilizers at phase flowering increases the earliest and total yield. The application of the technological complex of activities including fertilization with mineral fertilizers Nı6P20K22, treatment of seeds with organic fertilizers Nagro and Stimix, and spraying of plants with conventional plant protection products leads to reduction of attack from Phytophthora infestans and Alternaria solani in tomatoes.

Аbstract. The present study examines the yields of the following essential-oil crops: oil-yielding rose (Rosa Damascena), peppermint (Mentha piperita), lavender (Lavendula angustifolia Mill.), coriander (Coriandrum sativum L.) and lemon balm (Melissa officinalis) in Bulgaria from 2003 to 2013 based on mathematical approaches. Correlation and regression analyses have been applied using the capabilities of the IBM Statistics SPSS 24 and the MS Excel 2010 software. The study proves the existence of positive correlations between ‘year’ and ‘yield’ of the lemon balm (r=0.609*), between oil-yielding rose and lavender (r=0.620*) and between lavender and coriander (r=0.766**) and negative association between ‘year’ and the peppermint yield (r=-0.700*). Between yields of other crops – oil-yielding rose, coriander and lavender, and between year and the yields from these crops there are no statistically proven relations. Linear regression equations are presented, showing the relation between the year and the quantity of lemon balm and peppermint production.

Abstract. This study assessed the farmers’ knowledge of yam entrepreneurial skills in Ekiti State, Nigeria. Two-stage random sampling procedure was used to select 580 respondents. Questionnaire was used to collect data. Both descriptive and inferential statistics were used to analyse the data collected. Findings show that the majority of the respondents had access to yam entrepreneurial business training/seminar (75.5%), sources of information through agricultural extension agents (86.2%), radio (83.3%) and fellow farmers (79.5%), non-member of any crop related enterprise group (66.2%). The overall farmers’ knowledge of yam entrepreneurial skills was low among the majority (62.6%). Specifically, the knowledge level of respondents on cultivation skills (=67.0) was high while management skills (=39.5), co-operation/networking (=29.3), customer/marketing skills (=27.1) and opportunity skills (=21.3) of respondents were considered low. It was, therefore, concluded that farmers’ knowledge of yam entrepreneurial skills was low. Agri-entrepreneurship training in management skills, opportunity skills, customer and marketing skills, co-operation and networking skills is recommended and encouraging the less educated yam-based entrepreneurs to participate in the agri-entrepreneurship capacity building training.

Abstract. The study analyzed the technical efficiency among cowpea farmers in Mubi South Local Government Area of Adamawa State, Nigeria. Data were collected from 100 respondents randomly selected cowpea farmers using multi-stage, purposive and simple random sampling process. The result of the stochastic frontier production function shows that sigma squared was 0.656 and significant at 1% level, indicating good fit and correctness of the distributional form assumed for the composite error term. The value of gamma was 0.522 and significant at 1% level, suggesting that 52% of the variability in the output of farmers was due to differences in their technical efficiency. The coefficients of farm size, seed, fertilizer, agro-chemicals and labor were positive and significant at varying levels indicating direct relationship with output of cowpea production. The analysis of the inefficiency variables revealed that education, farming experience and extension contact decreases technical inefficiency of the farmers. Mean technical efficiency (TE) was 0.78 with the minimum and maximum values of efficiency as 0.53 and 0.97, indicating that farmers have the potential to increase their TE by 21.2% in the short run given the current state of technology. To achieve this, policies by the government and nongovernmental agencies should be geared towards encouraging farmers’ education on farm management practices so that they would be able to allocate production resources more efficiently especially fertilizer and herbicide for optimum yield.
