“…Dalam hal ini bahwa bobot badan sangat dipengaruhi oleh kondisi lingkungan (Mia et al, 2013) Heterozigositas ini paling sering ditemukan pada tingkat variasi fenotipik, namun juga bisa ditemukan untuk komponen variasi individu. Perbedaan yang didapatkan tersebut mempengaruhi perkembangan pada suatu populasi tertentu (Mandal et al, 2022). Faktor genetik yang di pengaruh gen dan kromosom dapat mempengaruhi pewarisan sifat fenotipe pada keturunan selanjutna.…”

The ewe Jawarandu goat is one type of livestock that is currently developing both on smallholder farms and industrial-scale farms. The effect of the application of management on goats productivity is reflected in the quality of the qualitative and quantitative traits that develop in goats. This study aims to determine the qualitative and quantitative characteristics of ewe Jawarandu goats in smallholder farms and livestock industries in East Kalimantan. This research was conducted in two places, namely community farms in Lempake Village, Samarinda Utara District, and at PT. Equalindo Farm, Tenggarong Seberang, East Kalimantan. The study used a purposive sampling method, namely the collection technique according to the criteria determined by the researcher, with goats aged 6-24 months. Sampling data using total sampling with all the population according to the criteria as a sample. The results of study stated that the ewe Jawarandu goats in East Kalimantan were dominated by white-brown goats. The results of quantitative characteristics show that average body size in smallholder farms is sequentially higher at body length 57.81±7.35, chest circumference 63.5±6.62, shoulder height 61.31±5.96, and body weight 23. ,65±7.35, while on an industrial scale, the average value was lower with successively at body length 52.54±3.83, chest circumference 60.72±4.28, shoulder height 56.18±5.79 and body weight 19.53±3.42. Several factors that can affect the qualitative and quantitative differences in goats in two different managements are related to the application of management, especially livestock selection, and factors adaptation to the environment. The relationship between selection and adaptation affects goat's productivity.

This research investigated the genetic and phenotypic characteristics of sexual dimorphism (SD) for body weights at birth (BW), weaning (WW), 6 months (6MW), 9 months (9MW), and 12 months (12MW) in Sangsari sheep. The records were retrieved from a dataset collected between 1986 and 2016 at the Sangsari sheep breeding station. The GLM method in the SAS program was applied to evaluate the environmental factors. The genetic analyses were accomplished using the AI-REML method of the WOMBAT software. Six bivariate animal models without or with maternal effects were used for genetic assessment traits in male and female lambs. Male lambs weighed more than female lambs and a weight difference of 0.21 kg (7.22%) at birth increased to 3.91 kg (13.95%) at yearling age. Levels of sexual dimorphism were relatively low and varied from 1.07 for BW to 1.16 for 12MW. For all traits except 12MW, \({{\sigma }}_{\text{a}}^{2}\), \({{\sigma }}_{\text{e}}^{2}\), \({{\sigma }}_{\text{P}}^{2}\), \({\text{h}}^{2}\), and \({\text{C}\text{V}}_{\text{a}}\) were higher in male lambs. Heritabilities for BW, 3MW, 6MW, and 9MW in male lambs were 3.18%, 4.53%, 24.05%, and 18.97% more than female lambs. For 12MW, the heritability of females was 23.83% more than males. Direct genetic correlations (rg) between the sexes ranged from 0.89 for 6MW to 1.00 for 9MW and 12MW, indicating that selection for body weight in males would result in a correlated response in females and consequently, would prevent phenotypic divergence. Cross-sex maternal permanent environment correlations (rpe) were 0.71 for 6MW and 0.98 for 3MW and 9MW. The values of rg and rpe for 6MW differed from 1.00, implying the presence of sexual dimorphism for additive genetic effects and maternal effects on 6MW.
