Determination of Milk Yield Characteristics in Private Dairy Cattle Farms in Mus Province

Abstract

This research was conducted to determine the reproductive activities and the affecting factors of dairy cattle farms in 346 farms of Mus province and its districts. Farms were based on 74.1% of jumping on other animals. 56.2% mucus discharge and 44.5% bellowing of animals as the primary sign of heat. For the first insemination, 52.6% of the herds were inseminated and 30.9% were seeded freely in the herd. Natural insemination of cows was 47.3% and preferred artificial insemination was 33.7%. The percentage of farms with reproductive problems and non-reproductive problems was 27.0% and 25.1%, respectively. while the rate of those who had sometimes problem was 38.1%. Postnatal insemination was found in the first resentment (33.8%), after 45 days (35.3W, and two months later (30.9%). Winter and spring were preferred as calving season. The effect of the location of the farms on the properties was found to be significant. This situation has been determined to have a significant effect on breeds grown in Farms. In order to bring the reproductive characteristics to the desired limits, it is recommended to take some precautions such as improving the feeding and shelter conditions and increasing the technical knowledge level of breeders.
