Individual mid lactation milk samples of 75 ml of each were collected from 95 Red Sindhi cows in first, second, third and fourth lactation period maintained at Livestock research station, Hosur. Effect of genotypes of -LG AA, AB and BB on milk fat% , protein%,Casein%,Total solids% and 305 days milk yield were analysed by completely random design by least square analysis. -LG genotypes (AA, AB and BB) were found to be having highly significant (P0.01) effect on Fat% during first and second lactation and significant effect (P0.05) during third and fourth lactation respectively. -LG genotypes were found to be having significant effect on protein% during first, second, third and fourth lactation periods. Genotypes of -LG were found to be having significant effect on casein% during first lactation and highly significant effect during second, third and fourth lactation periods. -LG genotypes were found to be having significant effect on total solids % during first lactation period only and no significant effect during second, third and fourth lactation periods. -LG genotypes were found to be having highly significant effect on milk yield during first and third lactation period and significant effect during second and fourth lactation periods.<#LINE#>Chung E.R., Han S.K. and Rhim T.J.@Milk Proteinpolymorphisms as genetic marker in Korean native cattle@Asian Australian J.

In Benin, there is beginning to be awareness in oyster as a protein resource. The present study aims to investigate the efficacy of the traditional purge method of oysters (Crassostrea gasar) used in lakeside villages of southern Benin. Thus, four lakeside villages characterized by high activity of collection and parking of oysters were chosen. There are Azizakouè, Djondji, Dègouè and Meko. In each lakeside village, a semi-structured survey was conducted and five parking stations were selected for the study. This survey was also coupled with the sampling of oysters before their parking. After three months of parking, sampling was again conducted to assess the efficacy of the parking on the quality of oysters. Results indicated that, before parking, microbial load of coliforms in oyster samples was high (24.106 - 3.109 ufc/g) with the presence of E. coli and Salmonella spp. However Vibrio spp was not detected in the analysed samples. Chemical pollution characterised by heavy metals such as copper and lead were also detected. After 3 months of parking, the results of microbiological analyzes indicated that the treatment was more effective in Azizakouè where the average microbial load has significantly decreased (p<5%) and at Djondji where the value rose from 107 cfu/g to 106 cfu/g. However, the results obtained on stations of Meko and Dégouè indicated that the treatment was ineffective. Results of chemical analyses after the parking of oysters, indicated that, this technique had reduced the lead content (15.96% in samples of Azizakouè, 60.30% in samples of Dégouè, 36.88% in samples of Djondji and 61.65% in samples of Meko), but was ineffective on copper content of oysters.<#LINE#>Nwajei G.E., Obi Iyeke G.E. and Okwagi P.@Distributionof Selected Trace Metal in Fish Parts from the RiverNigeria@Res.
