Abstract

The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

Abstract

The objective of this study was to determine histomorphological change of seminiferous tubules, sperm quality and testosterone level after administration and cessation of pegagan extract. The research used 4x2 factorial complete randomized design, the first factor was dose-administration duration and the second factor was cessation length of pegagan extract. Parameters consisted of degree of spermatogenesis, sperm quality (motility, concentration and abnormality), and testosterone level. The data were processed using analysis of variance and Duncan’s test. Results showed that there was no interaction between dose-administration duration and cessation length. There was no significant difference of dose-administration duration of pegagan on degrees of spermatogenesis, sperm motility and testosterone level. Cessation length did not significantly affect degrees of spermatogenesis, sperm motility, and testosterone level although these results indicated that cessation of pegagan extract for 12 days increased degrees of spermatogenesis and sperm motility, indicated the antifertility potency of pegagan extract. In conclusion, Pegagan extract has potency as anti-fertility agent although the degree of spermatogenesis, sperm quality and testosterone levels were still in the normal range for the reproductive process and not irreversible, and pegagan could be explored as an reversible anti-fertility agent.

Abstract

In this study the determination of micro mineral elements (selenium, iron and zinc) in meat, spleen and liver of beef were carried out. Brahman cross steers reared under intensive production system in feedlot for 87 days. Samples of meat, spleen and liver were collected from 16 steers aged 24-36 months with four types of feeding treatment, feeding without Se (group I) and feeding with additional supplementary of 0.3 ppm selenium for 25, 50 and 75 days (group II, III and IV, respectively). Samples characterization were carried out by instrumental neutron activation analysis (INAA) using irradiation facility in G.A Siwabessy Serpong reactor. Analysis results showed that there is an increasing of selenium content in meat and liver after 75 days feeding. The mean of selenium in liver for group I, II, III and IV were 0.13, 0.17, 0.20 and 0.31 mg/kg wet weight, respectively, while for liver were 0.43, 0.53, 0.60 and 0.70 mg/kg wet weight, respectively. The mean concentrations for iron in meat, spleen and liver were 11.85, 139, and 38.94 mg/kg, respectively, for zinc were 27.90, 21.70 and 25.27 mg/kg, respectively. In this study, the meat and liver contribute more than 100% of recommended daily allowance (RDA) of Se for children and adults. Spleen have contribution of RDA of Fe 53 to 154%, while the RDA of Zn is contributed mostly from meat by 21 to 56%.
