Abstract

The aim of the research was to identify the qualitative characteristics of Bali polled cattle.  Several advantages in polled cattle can reduce the risk of injury that often occurs in herdsmen’s caused by horns, can prevent bruising of the carcass and damage to the skin. The development of Bali polled cattle requires further research, this research is related to its qualitative characteristics. The total sample was 100 consisting of 11 Bali polled cattle and 89 Bali horned cattle, consisting of 42 samples from Bone Regency and 47 samples from Barru Regency.  Qualitative characteristics that are measured include: coat color, blackline runs along the back, color of socks, color of rump, muzzle color, eyelid color, white hair in the ears, and wattle size.  The qualitative characterization of Bali Cattle in this study was based on the Indonesian Institute of Sciences (LIPI) ́s guidelines for phenotypic characterization. The distinctive characteristics found in horned Bali cattle are also found in polled cattle. The presence of Bali polled cattle changes the indigenous cattle rearing system in Indonesia.

Abstract

This study aims to determine the population dynamics, population structure, and increase of Bali cattle population Maiwa Breeding Center partnerships in Barru Regency. This research was conducted from March to April 2020 in Barru Regency, South Sulawesi. The Reproductive Efficiency of Bali cattle was 91%. Population dynamics were only influenced by the calving, mortality, and sale of livestock, with the growth of 27% (2019) and 31% (2020). The population structure was dominated by cows, 31% (2018), 48% (2019), and 54% (2020). Natural Increase (NI) of livestock was 17% (2018), 28% (2019) and 20% (2020). The conclusion of this study is that the growth of the Bali cattle population of MBC partnerships was still low when according to calving and income because it does not reach 80% of cows based on population even shows a tendency to decrease calving. Keywords: Population of dynamics, population of structure, Bali cattle, smallholder partnerships

Abstract

Semen extender is closely related to the success of artificial insemination to achieve maximum results. Extender aims to increase the volume of semen, provide food substances as a source of energy for spermatozoa provide buffers to maintain pH, osmotic pressure, and electrolyte balance, and prevent the possibility of germ growth. This study aims to determine the effect of extender on the quality of Bali bull spermatozoa through an alternative approach, one of which uses Tris-Egg Yolk powder extender, which is efficient and effective. The study was designed randomized, with three treatments and five replications. The treatment combinations were P0 (Tris-Fresh Egg Yolk 20%), P1 (Tris Oven Egg Yolk 20%), and P2 (Tris-Commercial Egg Yolk 20%). The results of analysis of variance showed that in the parameters of progressive motility, viability, abnormality and intact plasma membrane, treatment of P0 (Tris-Fresh Egg Yolk 20%) tended to be similar as treatment P1 (Tris-Oven Egg Yolk 20%) (P>0.05), but in P2 (Tris-Commercial Egg Yolk 20%) was significantly lower (P<0.05) than P0 and P1. It can be concluded that oven egg yolk powder mixed with tris solution can maintain sperm quality after dilution. Keywords: Oven egg yolk powder, commercial egg yolk powder, buffer solution
