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 purpose of this study was to determine the development of spermatogenic cells and sperm quality after administration extracts of pegagan (Centella asiatica) in various doses and duration of administration. The research was carried out with complete randomized design (CRD), consist of 16 combinations of dose and duration of treatment. Parameters measured consist of population of spermatogenic cells (spermatogonia, primary spermatocytes, late spermatids) and sperm quality (concentration, motility, abnormality). The data were processed using analysis of variance (ANOVA), and differences between treatments followed by Duncan test. The results show that both the dose and duration have very significantly (p < 0.01) affect on decreasing of late spermatid population, sperm motility and concentration, but not for population of spermatogonia, primary spermatocytes and sperm abnormalities. The decrease of population and quality may due to antifertility effect of pegagan, eventhough still in the normal range. It is concluded that spermatogenic cells development and sperm quality reduce after administration of pegagan extract, although infertility is not yet found up to the dose of 450 mg/kg BW for 49 days duration of administration. Key Words: Spermatogenic, Sperm Quality, Pegagan Extract
