Abstract

This study had a purpose of obtaining potential indigenous yeasts for assimilating cholesterol and assessed the in vitro activity of Bile Salt Hydrolase (BSH) using Chloramphenicol Yeast Glucose (CYG) media supplemented CaCl2 and Taurodeoxycholic Acid (TDCA). Yeasts were collected from the gastrointestinal tract of Indonesian native chicken (Gallus javanicus), Javanese duck (Anas javanicus), and Muscovy duck (Anas moschata). The BSH assay was performed to determine secretion of BSH from yeast strain to conjugate bile salts into cholic acid-free by measuring precipitation zone in a specific medium. The quantitative measurement to assimilate cholesterol in yeast using CYG broth contained soluble cholesterol (500 ppm) and incubated at 30°C for 72 hours. Microplate reader used to analyze cholesterol content in the supernatant. Data were analyzed using Analysis of Variance (ANOVA) with one way completely randomized. Precipitation zone found among isolates did not significantly different (P>0.05). Isolate B-18 from Javanese duck performed the highest percentage of assimilating cholesterol with the value of 51.83% and identified as S. cerevisiae. This isolate was closely related to S. cerevisiae mt 21s (accession number X00149.1)based on phylogenetic tree analysis. It could be concluded that S. cerevisiae B-18was potential for assimilating cholesterol in vitro.

Abstract

Present study aimed to determine the effectivenessof dimethylformamide (DMF)as cryoprotective agent (CPA) by determining its optimum concentration inTris Eggyolk (TEY) extender on the quality of post-thaw swamp buffalo semen. Only ejaculates having > 60% sperm motility were divided into eight s tubes. Four tubes were diluted in TEY with 4, 5, 6, 7% of glycerol and four other tubes were diluted in TEY with 4, 5, 6, 7% of DMF. Diluted semen then packed into ministraw (0.25 mL), equilibrated at 4°C for 4 hours and freezed at 8 cm above liquid nitrogen vapour for 10 minutes and then stored at liquid nitrogencontainer. After 24 hours of storage, straws were thawed at 37°C for 30 seconds. The result showed that sperm motility after equilibration tend to be the same at all four glycerol concentrations, whereas the decrease in motility was highest in extenders with a DMF concentration of 7% (P <0.05). Post-thaw sperm motility and recovery rate in TEY extender containing 5% DMF or 7% glycerol were highest (P<0.05) than other glycerol or DMF concentration. Sperm viability and membrane integrity did not differ among TEY containing 6% or 7% glycerol, both  were higher (P<0.05) than 4% or 5% glycerol. Viability and membrane integrity of sperm in 5% DMF was superior (P<0.05) to 4%, 6% or 7%. This research concluded that 5% DMF or 7% glycerol was considered to be the most suitable CPAs for swamp buffalo semen cryopreservation.

Abstract

An experiment was conducted to compare the growth curve of rabbit. Three breeds of rabbit,namely Indonesian Local Rabbit (IL), Flamish Giant (FG) and Rex (R) were used in the study.Individual body weights of each breed was measured from birth to 63 days of age with 3-days interval.Those periodical data were separated into different sex, be then it was averaged to analysis growthpattern. Growth curve parameters were estimated to fit growth data. There was no difference in bodyweight between sexs within breed. Indonesian local rabbit had the lowest body weight. The resultsshowed that growth curve paramaters among three breeds were significantly different (P<0.05) for bothsexes. FG had the highest value of asymptotic mature weight, followed by R and IL. In conclusion,Gompertz model was excellent fit for the growth data in rabbit with a high coefficient determination (R2= 0.999).

Abstract

The research was conducted to evaluate the effect of mulch and mixed cropping grass – legume atsaline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in thisresearch was classified into strongly saline soil with low soil fertility. The research was arrranged inrandomized complete block design with 3 blocks. The treatments were : M1 = guinea grassmonoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grassmonoculture, 6 ton/ha mulch, M4 = mixed cropping grass with Sesbania grandiflora, without mulch;M5 = mixed cropping grass with Sesbania grandiflora, 3 ton/ha mulch; M6 = mixed cropping grass withSesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed byDuncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegumewith 6 ton/ha of mulch. The effect of mulch at saline soil significantly increased plant growth,forage yield and nutritional quality of guinea grass. Application of 3 ton/ha mulch increased plantgrowth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritionalquality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Abstract

The aim of this study was to determine the influence of pre-freezing different procedures to the quality of Ettawa Grade goat frozen semen-sexing. The research material was semen sexing consisted of 2 layers those were top layer and bottom layer. The quality of frozen semen sexing was observed by comparing the pre-freezing technique (factory standard operating procedure: FSOP) according to the  Artificial Insemination Center operating procedure (pre-freezing by placing the straw of semen for about 4 cm above liquid nitrogen for 9 minutes) with the modification procedure (MP), pre-freezing by placing the straw of semen 16 cm above liquid nitrogen for 9 minutes and then it was lowered to 4 cm above liquid nitrogen for 9 minutes during the pre-freezing phase. The parameters observed were motility, progressive motility, hyperactivation, and sperm linearity. Data were analyzed using Student's t-test.The results of this study indicated that the quality of sexed-semen in the standard operating procedures of frozen semen compared to the treatment of modifications to the top and bottom layers were motility at the top layer (46.06 ± 7.52% vs 55.6 ± 7.78%) and bottom layer (36.82 ± 6.49% vs. 41.47 ± 6.57%); progressive top layer (16.34 ± 4.27 vs. 32.83 ± 5.9%) and bottom layer 15.97 ± 2.72% vs. 19.79 ± 3.97%); hyperactivity in the top layer (0.81 ± 0.6% vs 4.09 ± 1.98%) and the bottom layer (0.71 ± 0.68% vs. 1.50 ± 1.05%); linearity consisted of linear and non-linear, the top layer (12.19 ± 2.94 vs. 20.52 ± 3.97%) and bottom layer (12.32 ± 2.63 vs 14.70 ± 2.6); while non-linear in top layer (0.14 ± 0.2 vs 0.68 ± 0.85%) and bottom layer (0.4 ± 0.13% vs 0.34 ± 0.4%). The conclusions in this study indicated that the quality of the frozen sexed-semen that has processed by pre-freezing modification technique was better than the frozen sexed-semen obtained from the Artificial Insemination Center Standard Operating procedure.
