Report on mare's milk analysis

The objective of the study was to estimate factors affecting mare's milk composition with the emphasis on the effect of different milk sampling. Milk samples, belonged to indigenous breed of the Slovenian draft horse (SDH), were collected on the farm registered for mare's milk production. Milk samples were collected during 8 test days (TD) from 3 routinely machine milked SDH mares in the age of 6 - 7 years with the estimated body weight from 600 to 656 kg in the 49 to 241 days of lactation. Two types (A and B) of samples were taken during 3 consecutive milking on the each TD. The A samples represented first jets of the milk while the B samples represented milk from each single consecutive milking per TD. The average milk yield per milking was 1.55 l. The average contents for B samples were: fat content (FC) 1.04%, protein content (PC) 1.75%, lactose content (LC) 6.74%, urea content (UC) 30.87 mg/dl, and somatic cell count (SCC) 3.02 x 10³/ml. The analysis of variance showed that sample significantly affected FC, UC, and SCC ; mare significantly affected MY, FC, PC, UC, and SCC ; stage of lactation affected MY, PC, LC, UC, and SCC ; and consecutive milking affected FC and PC. From the perspective of growing interest for mare's milk production, the safety and quality of mare's milk should be provided. This could be fulfilled by determination of the guidelines for breeders and standards for mare's milk recording in the near future.
