Abstract

The onset of puberty is an important role in order to optimize performance of Katingan cattle reproduction. The onset of puberty can be estimated from to blood progesterone concentration. In this study the onset of puberty was estimetid through analysis of progesterone hormone in various age of individual cattle. Thirty blood samples were obtained from 30 Katingan heifers of 13 months and 15 days to 23 months and 18 days old from Tumbang Lahang (10 samples) and Buntut Bali (20 sampels) to be analyzed for progesterone concentrations using RIA method. The same samples were also analyzed to find out information about Copper (Cu) concentration. The results showed that progesterone concentration varied narrowly from 0.008 to 0.184 ng/ml. The result indicated that the Katingan cattle in 23 months old was still in prepuberty category. Environment factor such as land pH was acid (pH<6), grass quality and climate in term of temperature and humidity relatively high, may an important role to delay the oset of their puberty. One of the environment problem was proved by the most of the same samples than had under adequate value of level of Copper.   Key Words: Katingan Cattle, Progesterone, Puberty, Cu mineral, Environment

Abstract

The significant decline of spotted buffalo population nowadays brought this species into an endangered situation. To perform an integrated conservation project, we need some basic information and data related to the reproductive and genetics potency of this buffalo. The purpose of this study was to observe the effect of coat color variation to the sperm quality, in order to get focus on specific candidate gene that allegedly bring the causative mutation(s) and responsible for the different pigmentation expression. In this study, we compare the quality of fresh and frozen-thawed epididymal sperm from 12 spotted bulls (that classified in 3 different spotted types, i.e Saleko, Bonga, and Lotong Boko) with five solid bulls. The results showed that there were no significant differences (P > 0.05) in all parameters of fresh and frozen-thawed epididymal sperm among those groups. The percentage of frozen-thawed progressive motility from Saleko, Bonga, Lotong Boko, and Solid was 44%, 42%, 40% and 42%, respectively. Moreover, the percentage of livability and membrane integrity of frozen-thawed sperm from each groups were 64.9%; 65.2%; 62.6%; 62.7% and 64.6%; 67.1%; 64.5%; 64.1%. In conclusion, it suggested that the coat color/phenotype difference has no effects on the quality of fresh and frozen-thawed epididymal sperm of spotted buffalo.
