The present research was conducted to determine the effect of season, lactation number and type score factors on the somatic cell count (SCC) in Black and White cattle raised in the Mediterranean climate zone. 1368 milk samples obtained from 128 cattle were analysed for SCC determination. Significant effects of season, lactation number and type scores on SCC were observed. The results indicate that the necessity to comply with the care and barn cleaning of the cows in the summer and the importance of the type characteristics in the selection programs may be effective in reducing the of SCC.

This study was conducted to determine milk yield characteristics and its effect on genotypes, years and ages Hair goat x Saanen crossbred and Hair goat breed between 2011-2012 years in private enterprise which is located in Amasya province Sarılar village. In this study, the effect of genotypes was found significant on average daily milk yield, lactation length and lactation milk yield in 2011 and 2012 years. In 2011, the effect of goat ages were determined on average daily milk yield (ADMY) and lactation milk yield (LMY) for all goat genotypes. In 2012, the effect of goat ages was determined on average daily milk yield and lactation length (LL) for all goat genotypes. The effect of year F1 and Hair goat were found significant on ADMY, LMY, and LL. The effect of year was found significant on only LL for G1 genotype. As a result it can be say that Saanen goat x Hair goat crossbred F1 and G1 genotype milk yield was higher than Hair goat reared in farmer conditions.
