People Breeding Station is a Bali cattle breeding instalation that was established by the Livestock Services of Bone Regency to maintain perform preservation breeding stock of Bali cattle. The research aims to analyze the differences body weight and morphometric of Bali cattle at different age proups in the area of People Breeding Station (PBS) and Non People Breeding Station (NPBS). The total number of measurable Bali cattle was 204 heads each consisted of 96 male and 108 females from PBS and NPBS. Mean and standard deviation of body weight Bali male cattle at PBS was significantly higher (p<0.01) than body weight of cattle at NPBS of the same age groups. Mean and standar deviation Bali of body weight male cattle mature (2.6-3.0) years in PBS is 246.58 ± 34.54 kg and in NPBS 187.17±21.67 kg. Mean and standard deviation body weight of Bali female cattle in PBS significantly (p<0.01) higher than in NPBS for age 0.1-1.0 and 1.1-2.0 years group but body weight for 2.1-3.0 and 3.1-4.0 years groups in PBS non significantly (p>0.05) than in NPBS. Mean and standard deviation body weight of Bali female Cattle age 3.1-4.0 years in PBS is 216.46 ± 32.87 kg and in NPBS isw 198.85±5.32 kg. All of morphometrics data was found that such as body lenght (BL), shoulder height (SH) and chest circumference (CC) of Bali cattle increased with the age advancement. Morphometrics of Bali cattle for age less than 3 years in PBS significantly (p<0.01) higher than Bali cattle in NPBS. In conclusion, the body weight and morphometrics of Bali cattle at PBS was higher than those at NPBS.

Many factors affected the milk production and milk quality of dairy cattle, such as the breed, age, type of feed, months of lactation, time milking and others. The purpose of this study was to determine the differences in milk production and milk quality in the morning and afternoon milking of dairy cows given corn cobs fermented. The study was carried out for one month, using eight lactating cows, divided into two groups each consisting of four cows. P1= complete feed + 40% of elephant grass, P2= complete feed + 20% of elephant grass + 20% of fermented corn cobs. Data analysis was displayed in chart form, the average and standard deviations and analyzed descriptively. The results showed that milk production in the morning milking treatment P1 was 18.36 %, higher than in the afternoon milking and P2 milking morning treatment was 11.56%, higher than in the afternoon milking or the second average morning milking treatment 14.96 % higher than afternoon milking. The milk production of group P1 which not given corn cobs fermented was 8.54 ± 2.78 L/h/d in the morning which was higher than the afternoon milking with average milk production 5.89 ± 1.89 L/h/d, while in the cattle group (P2) which gets fermented corn cobs, milk production in the morning milking was 8.40 ± 1.68 L/head/day, higher than with the afternoon milking with an average milk production of 6.65 ± 1.59 L/h/d. The quality of milk at morning milking was showed from the protein content (3.26%) and fat (3.37%) lower than in afternoon milking with the protein content of 4.03%, and fat content 3.79%. In conclusion, the research showed that milking in the morning has higher milk production than milking in the afternoon, while milk quality in the afternoon milking is higher than in the morning milking.

The aim of this research is to understand the effects of katuk and gamal leaf supplementation on production and quality of milk at early lactation period. The research was conducted in dairy cattle husbandry, Enrekang, with completely randomized design consisting of 4 treatments and 4 repetitions, yielding totally 16 experimental units. The experimental diet was made of forage (60%), concentrate (25%), gamal leaf (15%), and katuk leaf (135 g, 155 gr, 175 g). The results showed that supplementation with katuk leaf significantly contributed to production of milk. The diet enriched with katuk leaf of 155 gr and gamal leaf of 15% (treatment P2) was evidenced to exert desirable effects on consumption and digestibility of the forage as source of fibers.

This study aims to determine the effect of katuk and gamal supplementation on dry matter digestibility, organic matter digestibility, and dairy milk quality of Friesian Holstein. This study was conducted at the Dairy Farm in Enrekang Regency. Sixteen heads of Friesian Holstein dairy cows having body weight ranged between 350 and 400 kg were randomly assigned to one of four treatment diets according to a completely randomized design (CRD). The number of replication for each treatment was four giving the total number of the experimental unit of 16. The treatments were supplementation of the ration consisted of forages (60%), concentrate (25%), and gamal leaves (15%) with either 0 g (P0), 135 g (P1), 155 g (P2), or 175 g (P3) of katuk. The results of the study indicated that supplementation of a ration containing Gamal (Gliricidia sepium) with different levels of katuk (Sauropus androgynus) significantly influenced the digestibility of dry matter and organic matter as well as the milk quality. Among the treatments, the P2 treatment (katuk supplementation of 155 g/d) showed the highest significant effects on improving the feed digestibility of the ration and the quality of milk.

The quality of semen is one of the most important things in the reproductive process. The aim of this study was to determine differences in the quality of frozen semen at various breeds of bull. This study was conducted for two months from May to June 2020, at the Laboratory of Animal Reproduction, Faculty of Animal Science, Hasanuddin University. The materials used in the study were frozen semen of bull at different breeds; Angus (AG), Brahman (BM), Fries Holland (FH), Simmental (SM), Limousine (LM), and Bali (BL), that were provided from the Livestock and Animal Health Services of South Sulawesi Province. Supporting materials were warm water at 40°C, alcohol 70%, liquid nitrogen. A completely randomized design one-way ANOVA using six treatments and three replications was used in the present study. The treatments in this study were a different breed of bulls. The results of this study showed that sperms’ motility at different breeds of the bull differed significantly (P<0.05). Sperms motility of AG and BM had significantly (P<0.05) higher than sperms motility of FH and BL (58.8% and 56.8% vs. 41.1% and 44.0%), and had a tendency higher than in SM and LM (59.7% and 49.2%). The viability of the sperms among breeds had relatively similar each other, ranging from 46.9% to 60.8%, however, BL viability had significantly (P<0.05) lower than the other breeds. Likewise, sperms abnormality was relatively similar among breeds, however, the highest abnormality was found in BL. It can be concluded that there were differences in motility, progressive motility, viability, and abnormality of frozen semen among the different bulls breed; in which Simmental had better quality than the other breed.
