Abstract

Reproductive potential should be routinely evaluated because it significantly impacts the farmer's economy and the cattle population in ruminant development areas. This study aims to assess the reproductive potential of cows in the Amahai sub-district, which is one of the development points for the industrial livestock area in Maluku Province. Purposive and random sampling methods selected 98 cows owned by 30 breeders from 3 villages. Cows were evaluated for their reproductive performance, whereas breeders' evaluation was focused on general characteristics and rearing systems, and the results were analyzed descriptively. The results showed that the potential reproductive value of cows in Amahai was generally considered promising because of the high percentage of calves born alive (97.98%), low rate of stillborn (1.13%), and abortion (1.1.7%), there was no history of dystocia. The population was dominated by cows with mediocre body condition scores (93.88%). Conversely, cows in this area have too young a first mating age (11.3 months), service per conception > 1 (2.65), and long days open (4.71 months). This reproductive potential will be maximized if breeders understand the mating season, recognize estrus signs, implement a short weaning period (≤ 2 months after parturition), and make reproductive records.

Abstract

The aim of this research was to determine the ability to detect lust and determine the correct mating time by farmer-breeder respondents in East Taniwel District, West Seram Regency. The research method is a survey method and the sample villages and respondents are determined based on the purposive sampling method. The variables observed consisted of: the ability to detect lust, determining the time of mating after parturition and maternal productivity (including; age at first marriage, pregnancy rate, birth rate, postpartum mating and pre-weaning child deaths. The results showed that 86.66% of respondents were farmer farmers in East Taniwel District has the knowledge, ability and skills in detecting postpartum heat in the medium category (able to name 2-3 categories) and 100% do not have the knowledge and ability in determining the right mating time after parturition. The potential productivity of Bali cows is age first mating 18.2 ± 1.16, pregnancy rate 88.01%, birth rate 98.85%, postpartum mating 4.8 ± 0.8, and pre-weaning mortality 8.90%.
