Abstract

This study aims to determine the population structure and reproductive potential of goats in Kesui Watubela District, East Seram Regency. The method used in this study was a survey. The determination of sample villages and respondents used a purposive sampling method. The selected sample villages were Tanah Baru Village, Kulwar Village, Kelbultak Village, ADM Guliar Village, and Tamher Timur Village, with 10 respondents selected from each village. The variables observed in this study consist of General Variables consisting of Age, Education, Occupation, Source and Method of Selecting Seeds, Length of Business and Maintenance System and Special Variables consisting of Population Structure and Reproductive Potential of Goat Breeders including Age of First Mating, Pregnancy Rate, Litter Size, Type of Birth and Pre-Weaning Mortality. The results of the study showed that the structure of the goat livestock population at the research location was dominated by Adult Females 200 heads (27.2%) then successively followed by Young Females 171 heads (26.84%), Young Females 116 heads (15.7%), Young Males 112 heads (15.2%), Young Males 101 heads (13.7%), and Adult Males 89 heads (12.1%) and their reproductive potential was Age of First Mating 9.1 ± 0.8 months; Pregnancy Rate 89.47%; Birth Rate 1.23 / mother / birth; Type of birth: Single birth 76.70% and twins 23.29%; Pre-weaning mortality 8.2%

Abstract

This study aimed to identify the morphological characteristics and fetometric parameters of Bali cattle fetuses obtained from the Municipal Abattoir (RPH) of Ambon, and to examine the relationship between Crown–Rump Length (CRL) and gestational age. Thirty fetus samples were collected and measured using a measuring tape and a digital scale. Observed fetometric parameters included CRL, head length, head width, head circumference, and fetal body weight. Data were analyzed descriptively to determine the relationship between fetometric size and gestational age. Results showed that fetal morphology developed consistently with increasing CRL. At CRL 21–31 cm (±90–120 days), skin pigmentation and tactile hair appeared; CRL 32–44 cm (±120–150 days) indicated external genital development; CRL 45–56 cm (±150–180 days) showed hair growth on the tail and ears; and CRL 57–70 cm (±180–210 days) exhibited morphology similar to newborn calves. The relationship between CRL and gestational age followed a non-linear pattern consistent with physiological fetal growth. It was concluded that CRL and fetal weight serve as reliable indicators for estimating gestational age in Bali cattle. The fetometry-based prediction model developed in this study could be applied as a practical tool in field or abattoir conditions, although further validation with larger and more diverse samples is recommended.

Abstract

This research was prepared with the main aim of assessing and analyzing the reproductive performance of female Bali cattle raised by breeders in Lolongguba District. Determining the research area and selecting participants was carried out using a field survey approach, with the application of purposive sampling techniques, namely based on certain criteria that were relevant to the research objectives. The research location focused on three villages that were considered representative, namely Grandeng Village, Waegeren Village, and Wanakarta Village. The reproductive variables or parameters observed in this study include several important indicators, including the age of first mating in female Bali cattle, the conception rate or calving rate, the birth rate or calving rate, the time when lust appears after giving birth which is known as post partum estrus, the time between births or calving interval, and the calf death rate before weaning or pre-weaning mortality. The research results show that the average age of first mating for female Bali cattle is in the range of 1,94 ± 0 years. The conception rate obtained reached 81.72%, while the birth rate was recorded at 94,48%. In addition, the average postnatal estrus time 4,9 ± 0,6 and calving interval were each in the range of 13,9 ± 0.6 months, and, a pre-weaning mortality rate of 8,74%. These findings provide a general overview of the condition and reproductive performance of female Bali cattle in the study area.
