Qualitative indexes of milk of ewes the Original Valachian

The aim of study was to evaluate milk efficiency of sheep Original Valachian (OV). Observation took place in the period 2006-2009 and were involved 123 ovine. Samples were taken from the morning milking during the months April to August (method ET). Milking proces was realised mechanically. In 84 sheep were known genotypes AA (n = 13), AB (n = 18), BB (n = 53). After evaluation of essential components of ewe{\crq}s milk from flock of lambing ewes OV during lactation were found these average values: Fat (F) 4,90 g.100g-1, crude protein (CP) 5,94 g.100g-1, casein (CAS) 4,40 g.100g-1, serum protein (SP) 1,18 g.100g-1, lactose (L) 5,07 g.100g-1, dry matter (DM) 16,45 g.100g-1, solid not fat (SNF) 11,63 g.100g-1 and utilizable dry matter (UDM) 10,85 g.100g-1. Average daily milk yield of OV was 0,70 l. Effect of stage of lactation was provable on all the indicators in the level of significance 0,001. It was evidenced a statistically significant effect of the control year on the content of SNF (P{} BB (0,68 l.day-1) {>} AA (0,66 l.day-1). In AB genotype was found the lowest levels of these essential components F, CP, CAS, DM, SNF and UDM. Highly significant effect of genotype was found on content of L (P{} AB (5,08 g.100g-1) {>} AA (4,91 g.100g-1). Less significant effect was found on SNF (P{} AA (11,62 g.100g-1) {>} AB (11,54 g.100g-1). In genotype AA was found the highest values of F, CP, CAS, SP, DM. Both genotypes AA, BB showed the same content of DM (16,32 g.100g-1)
