Abstract

The aims of this research were to determine diurnal patterns of testosterone and cortisol metabolites to predict the testis functional status. In this study, fecal testosterone and cortisol were quantified in 77 samples from three male Hylobates moloch during a course of three months period. These data showed that the highest concentration of fecal testosterone occured at 18.00-06.00 (23.61 ng/g dried feces), then declined gradually. The lowest concentration was in the evening (5.54 ng/g dried feces). Our tests showed that there was a decrease in the mean testosterone concentration from 06.00-10.00 to 10.00-14.00 to 14.00-18.00. For cortisol, the highest concentration occured at 06.00-10.00 (597.84 ng/g dried feces), then decline gradually in the evening (225.73 ng/g dried feces). Key words: Hylobates moloch, feces, testosterone, cortisol, diurnal pattern

Abstract

The research was planned to yield the biologic potential synergism of MoAb-hCG in increasing the embryo number. Twenty five dairy cows were divided into five groups. The Control Group was superovulated with 2,500 IU PMSG intramuscularly (i.m.), the remaining of the Group II, III, IV and V consecutively after being superovulated by 2,500 IU PMSG were treated with MoAb intravenously (i.v.), hCG i.v., MoAb-hCG i.v. and MoAb i.v-hCG i.m. Data evaluation were analyzed using ANOVA and LSD test. The result showed that there were increasing in number of transferable embryo per donor produced (P<0.01) after application with either MoAb i.v. (9.6), hCG i.v. (9.4), MoAb-hCG i.v. (11.2), or MoAb i.v.-hCG i.m. (9.6). The Control Group produced only 2.4 embryo per donor. The combined MoAb and hCG in one treatment were not able to increase the embryo yield (P>0.05).Key words: MoAb, PMSG, hCG, superovulation, donor, embryo

Abstract

The experiment was carried out to study the use of direct transfer method in embryo cryopreservation by using two cryoprotectants and the effectivity of various concentrations of sucrose during cryoprotectant removal. Eighty-fourmorula stage embryos were divided equally into two groups and were treated by using 1.5 M ethylene glycol (EG) and 1.5 M 1,2-propanediol as cryoprotectant. The embryos were frozen using programmable embryo freezing machine on step by step decreasing temperature. Frozen embryos were thawed and cryoprotectants were removed either without sucrose (0 M) or with sucrose in concentration of 0.2 M, 0.4 M and 0,8 M. The results showed that the quality of the thawed embryos cryopreserved using 1.5 M EG was better than that using 1.5 M PROH. The survival rate on the embryos cryopreserved with 1.5 M EG (92.8%) was higher than 1.5 M PROH (78.6%) (P0.05). The viability of embryos exposed to 0 M, 0.2 M, 0.4 M and 0.5 M sucrose were 80.0, 80.8, 90.9 and 81.80% respectively. In contrast, by using 1.5 M PROH, rehydration with 0.4 M (83.3%) and 0,8 M (90.0%) sucrose was significantly better compared to those without (22.2%) or with 0.2 M (36.3%) sucrose (p

Abstract

                                                                 ABSTRACTThe objective of this research was to evaluate the quality of chilled canine semen in Tris-egg yolk (TEY) extenders containing different concentrations of sericin. Semen were collected from four dogs by massage method. Canine semen was collected using sterile urine pots and evaluated. Sperm-rich fractions were pooled and divided into four equal aliquots, which were then diluted with TEY extenders supplemented with different concentrations of sericin (0%, 0.1%, 0.25%, 0.5%). The diluted semen aliquots were preserved at 4 ℃ in sterile centrifuge tubes and were then evaluated for spermatozoa motility, viability, plasma membrane integrity and acrosome integrity every 12 hours up to 72 h. The TEY extenders supplemented with 0.25% and 0.5% sericin resulted in higher spermatozoa motility and viability at 72 h compared to other TEY extenders (P0.05). The integrity of plasma membrane and acrosome of spermatozoa showed no significant differences among the groups extenders at 72 h. In conclusion, sericin in concentration of 0.25% and 0.5% were able to prevent the motility and viability of canine spermatozoa after storage for 72 h.
