Abstract

With Croatia becoming a member of the European Union in 2013, the country faces numerous challenges and opportunities. The energy production from organic waste is less than 3 % of total energy production, although the potential is 10 times higher. It becomes evident that the agricultural sector can play an important role in reaching the country’s renewable energy target. Moreover, research and field trials indicate the opportunities for digestate as a replacer of mineral fertilizer. In order to boost the agro- energy sector, Sisak–Moslavina County joined the FP7 funded project - INEMAD (Improved Nutrient and Energy Management through Anaerobic Digestion, 2012-2016) - whose main goal is to reconnect livestock and crop production in a sustainable way. In order to investigate potentials, SMC, together with two Belgian partners (DLV Belgium, Innova Energy) prepared a feasibility study of the biogas potential for the pig farm K. from Osijek – Baranja County. The pig farm has a production capacity of 7.200 pigs. The feasibility study showed that for a farm of this size an optimal solution would be an installation of a small-scale digester. In the specific case, the plant of 38 kWel would allow the framer to spread the manure/ digestate more easily and generate electricity that could be used on the farm. However, the plant of 11 kWel. would be enough for covering the farm´s energy needs which allows farmer to use specific renewable energy sources focused governmental subsidies. Based on the biogas calculation tool, developed by DLV Belgium, the biogas unit of 11 kWel. could produce 54.000 m3/year of biogas (approximately 59.600 m3/year of biomethane). Another added value of the biogas plant implementation would be an improved nutrient management that would result in creating highly valuable organic fertilizer - digestate. This contribution provides insights in the feasibility study preparation and answers to farmer ownership questions on biogas production in organic farming that is similar in size and capacity.

Abstract

The study was composed of six levels of mushroom waste powder (0, 5, 10, 15, 20 and 25 grams MWP per kg of basal feed) supplemented to the basal feed of broiler chickens. The experiment was conducted in a completely randomized design in three replications to determine the effects of mushroom waste powder levels on body weight, feed consumption, feed conversion efficiency, average daily gain in weight, and meat quality of broiler chickens. Average daily gain (ADG) in weight and body weight (BW) negatively affected by MWP at the early age of broiler chickens, then slightly improved over time of feeding, but does not vary between treatments (P>0.05). Feeding broiler chickens up to 20 grams MWP significantly increased feed consumption (FC), however, a 25 grams MWP significantly decreased (P=0.01) feed consumption during 18 days period of feeding. Feed consumption efficiency (FCE) slightly improved over time but does not varies (P>0.05) with the control. Broiler meat quality varies significantly with the level of MWP in terms of texture (p=0.0017), tenderness, (p= 0.0001), taste p=0.049) and general acceptability (p=0.0018). However, within these parameters, meat quality of broilers fed with MWP at all levels generally does not vary from the control, except for T2 in terms of taste and tenderness where it is significantly lower compared to the control treatment. MWP does not compromise, in fact, slightly improved the meat quality of broiler chickens. A slight improvement of average daily gain in weight (ADG), body weight (BW), feed conversion efficiency (FCE) and meat quality; and a decrease in feed consumption (FC) with increasing levels of MWP is an indication that MWP is a potential feed additive in chickens. Another study to layer chickens and age of administration maybe done to investigate further the potential of MWP.

Abstract

The study examined factors influencing adoption of cassava processing technologies by women entrepreneur in South – West, Nigeria using primary data. A multistage sampling technique was used to select 373 respondents with the aid of a structured questionnaire. Descriptive statistics and probit regression model were used to analyse the data. Results revealed that majority (74%) of the women entrepreneur were under 50 years, 80% were married with an average age of 43 years. About 86.6% of the respondents had primary education with 51% of the respondents having 4 - 6 members per house. It further revealed that 67% of the women entrepreneur adopted improved technologies with cassava mechanical grater being the most used improved technology while the factors affecting adoption of the technologies were educational status, source of information, credit and raw material. It was also revealed that the challenges faced by the women entrepreneur were high cost of equipment, non-availability of the technologies, difficult to operate and lack of knowledge. The study concluded that there should be easy accessibility to improved technologies among women entrepreneurs.
