Muhammet Hanifi Selvi | Mete Yanar
In this study, genetic parameters, macro environmental factors and genetic, phenotypic and environmental trends for actual and 305 day milk yield of Brown Swiss cattle reared in Research Farm of Agricultural College at Atatürk University were estimated. Estimated breeding values that were used for calculation of the genetic trend and genetic parameters were estimated by using MTDFREML computer package program. Environmental factors affecting on actual and 305day milk yields were analysed by using Harvey statistic package program. While effects of the years and parities on the actual and 305-day milk yields were highly significant, the influence of the calving season was found to be insignificant. Environmental and phenotypic trends for actual and 305-day milk yields were determined as -33.2 kg and -29.0 kg; and -27.8±19.1 kg/year and -25.9±8.7 kg/year respectively. Genetic trends for actual and 305-day milk yields were calculated as 5.4±3.8 kg and 3.1±3.4 kg. Heritability’s for actual and 305-day milk yields were 0.21±0.12 and 0.16±0.14 respectively. Repeatability values for actual and 305-day milk yield were found as 0.29 and 0.33 respectively.

The economic evaluation for the production of fruit juice from the Africa star apple otherwise known as ‘Agbalumo’ in the south western part of Nigeria was evaluated using the NPV (Net Present value) and IRR (Internal Rate of Return) methods assuming a uniform cash flow over a 10-year plant life. Sensitivity analysis was conducted by varying the number of production days (330, 300 and 250 days) at 100% plant capacity and varying the plant capacity (100, 85 and 70%) for a 330-day production schedule. Some components of the operating cost reduced with number of days and plant capacities. The production cost and product cost per unit increased with either plant capacity utilization or the number of days. It was observed that product cost/ 500ml Tetra Pak of Agbalumo juice at 85% and 70% stood at ₦37.48 while payback time/profitability percent had better index at 300 and 250 days compared to 330 days of plant operation. The results further indicated that the plant should not be operated for less than 250 days and plant capacity utilization of 70% in the year. Flexibility in the plant capacity utilization in the range of 70%-85% for 330 days shows a good economic performance as well as result of the NPV and IRR for this operating condition.

The effect of different processing stages- defatting, solubilization, isoelectric precipitation, neutralisation and lyophilisation on the total phenolic content and protein content of Carica papaya (pawpaw) seeds (CPS) full-fat flour (CFF), defatted flour (CDF), protein concentrates (CPC) and protein isolates (CPI) was studied. The folin-ciocalteu procedure was used to assess the total phenolic concentrations of the Carica papaya products and results were expressed as gallic acid equivalent (GAE). Optimal protein content was estimated at pH 10 for all samples. Higher levels of polyphenols were extracted using water-methanol (20/80) mixture compared to 100% methanol. Total phenolic content (TPC) was demonstrated in a trend of CDF > CPC > CFF > CPI with CDF having the highest TPC. The finding suggested a more economical protein isolate production method. The study concludes that the processing of CPS into the various products (CFF, CDF, CPC & CPI) improves its protein and polyphenol content.

Forty seed sample of wheat (Triticum aestivum) were collected from four locations viz. Chitwan, Kaski, Banke and Lalitpur and tested by blotter method at laboratory during 2013 for determining fungal pathogens associated with wheat seeds in Nepal. Eighteen species representing thirteen genera of fungi were recovered from the seed. Alternaria alternata and Bipolaris sorokiniana were predominant in all the varieties/genotypes from all the locations, where B. sorokiniana was strongly pathogenic in wheat crop. Percentage frequency and type of fungi detected varied with variety and locations. Bipolaris sorokiniana was highest (64.40%) in Banke than remaining three locations. Seeds of Chitwan had lowest percentage (5.50%) of seed infection as compared to other locations. Relative abundance of Alternaria alternata (55.10%) was highest as it was the most prevalent component of seed borne mycoflora, followed by Bipolaris sorokiniana (34.69%) and Cladosporium herbarum (7.19%). Differences in quantity of precipitation and relative humidity might be the possible reason for variation in frequency and type of fungi detected in wheat seeds of four locations.
