ABSTRAK. Sapi potong merupakan salah satu ruminansia yang memiliki potensi besar sebagai sumber protein hewani di Indonesia. Tujuan penelitian ini adalah untuk mengetahui bobot badan, pertambahan bobot badan harian, dan jarak genetik sapi Bali pada tiga Kecamatan di Kabupaten Merangin Provinsi Jambi. Materi penelitian adalah sapi Bali umur I1 (12-24 bulan), sebanyak 180 ekor yang terdiri dari 30 ekor jantan dan 30 ekor betina di setiap kecamatan. Metode penelitian adalah metode survei, teknik pengambilan sampel secara purposive sampling dengan jumlah sampel sebanyak 180 ekor, yang terdiri dari 30 jantan dan 30 betina dan tidak dalam keadaan bunting. Data yang dihimpun meliputi bobot badan, pertambahan bobot badan harian dan morfometrik di tiga kecematan.

The beef cattle are one of the ruminants that have great potential in providing sources of animal protein in Indonesia. The purpose of this research was to determine the body weight, average daily gain, and genetic distance of Bali cattle in three sub-districts of Merangin district, Jambi Province. The research method was a survey method with purposive sampling technique, as many as 180 samples consisting of 30 males and 30 females in each sub-district and were not pregnant. Data collected include body weight, avarege daily gain and morphometrics between three sub-districs. The data body weight, avarege daily gain and morphometrics were analyzed using the average difference test (t-test). The average value vector body measurement of Bali catlle in three subdistrict was analyzed using the T 2 Hotelling statistical test. The main component analysis statistical test was used to determine the characteristics of the body shape and size of Bali cattle. The discriminant function can be used to analyze genetic distances, which can form a phylogenetic tree. The results of this research indicate of body weight, average daily gain and morphometrics of Bali catt...
This study aims to determine the determinants of size and shape of Simbal and Brahman Cross cattle in the West Pamenang sub-district, Merangin district. The method of this study was a survey with a purposive sampling technique. Sampling criteria included: Sample of each breeds consisted of 60 Simbal and 60 Brahman Cross cattle aged 1-2 years. Data observed included: body length, shoulder height, chest circumference, inside chest, chest width, canon circumference, hip height, body weight, and body weight gain. The differences in body measurements between Simbal and Brahman Cross cattle analyzed by T-test. Identification of the determinants of size and shape of Simbal and Brahman Cross cattle were analyzed using Main Component Analysis method. The results of this study were body weight, body weight gain, and body measurements of Simbal cattle were significantly different (P <0.05) higher than Brahman Cross cattle, both male and female. Simbal cattle and male Brahman Cross cattle were significantly different (P <0.05) higher than females. The conclusion shows that body weight, body weight gain, and body measurements of Simbal cattle are higher than Brahman Cross cattle. Male body weight gain was higher than females in both Simbal and Brahman Cross cattle. The determining factor for the body size of Simbal and Brahman Cross cattle is chest circumference, while the determining factor for body shape of Simbal cattle is the height of shoulders, while Brahman Cross is body length. The highest correlation between body measurements and body weight in Simbal and Brahman Cross cattle, both male and femal is chest circumference (LD).

The study aims to determine the relationship between egg characteristics and egg weight, DOC weight and body weight, to characterize the size and body shape of the first generation of Bangkok chickens aged 3 months. A total of 315 chicken eggs were used with the experimental method. Characteristics of eggs, egg weight, body weight, weight gain and body measurements, DOC weight and characters of weight and body shape were analyzed using a t-test. regression and correlation analysis and principal component analysis. T-test showed chicken males were higher than females (P<0.05). Egg characteristics are positively related to egg weight with a correlation value of 66.90% for males and 84.10% for females. DOC weight of male and female chickens was positively related to body weight at 1, 2 and 3 months of age, with correlation values of DOC weight with roosters respectively 73.40%, 67.90% and 65.10% and females 74.20%, 67 .00% and 52.40%. The body size characteristic of male and female chickens is chest circumference. The characteristic body shape of the rooster is the wing's length while the hen is the length of the upper body. Conclusion: there is a positive relationship between egg characteristics and egg weight and the highest correlation between egg girth and egg weight, DOC weight with body weight with the highest correlation at 1-month weight, the identifier of body size is chest circumference and body shape characteristics, is the wing length (male) and upper body length (female).

Spermatozoa dari epididimis hewan yang sudah mati merupakan pilihan menarik untuk preservasi gamet jantan. Penelitian ini bertujuan mengetahui pengaruh penyimpanan epididimis pada suhu 5 0C terhadap kualitas spermatozoa sapi Bali. Sebanyak 20 buah epididimis sapi Bali disimpan dalam refrigerator dengan suhu 5 oC, dialokasikan pada 4 lama penyimpanan yang berbeda yaitu kontrol, 24 jam, 48 jam, dan 72 jam. Peubah yang diamati meliputi motilitas, persentase hidup dan abnormalitas. Dari hasil penelitian ini didapatkan bahwa lama penyimpanan pada suhu 5 oC berpengaruh nyata (P<0,05) terhadap motilitas namun tidak mempengaruhi (P>0,05) persentase hidup dan abnormalitas. Motilitas turun pada 48 jam (62,23%) dan 72 jam (59,46%) dibandingkan kontrol (70,36%), sedangkan 24 jam (67,74%) tidak berbeda dengan kontrol. Dapat disimpulkan bahwa penyimpanan epididimis pada suhu 5 oC selama 72 jam mampu mempertahankan kualitas spermatozoa sapi Bali yang layak untuk inseminasi.
This study aims to determine the relationship between egg morphology and egg weight and DOC weight with body weight of Kampung F1 chickens. The research material was 174 free-range chickens from hatching 315 eggs. The method used: experimental method. Data collected: egg size, egg weight, body weight, body weight gain, and body size. Data on egg size, egg weight, body weight, body weight gain and body size were analyzed using a t-test. The relationship between variables was analyzed regression and correlation analysis. Characteristics of body size and shape were analyzed principal component analysis. The results showed that egg size, egg weight, body weight, body weight gain and body size of male Kampung chickens were different (P <0.05) higher than females. Egg size affects egg weight, and DOC weight affects body weight at 4, 8, and 12 weeks of age. Egg size was positively correlated with male and female egg weights. DOC weight was positively correlated with body weight of Kampung chickens aged 4, 8, and 12 weeks. The closest correlation between egg size and egg weight was egg circumference (0.913), and DOC weight with body weight was weight at 4 weeks of age (0.936). In conclusion, the relationship between egg size and egg weight, DOC weight and body weight were linear and had appositive values.
