The study was conducted to determine effect of EB or CS supplements in LAMP reaction on greater accuracy of sexing cattle embryos. Bovine ovaries were collected from the slaughterhouse, oocytes were aspirated from follicles then were evaluated morphology. Oocytes were cultured in TCM-199 at 38.5 ºC 24 h. For in vitro fertilization (IVF), oocytes were co-incubated with spermatozoa at 38.5 ºC 24 h. Fertilization rate was evaluated and then the embryos were in vitro cultured until morula stage. Then, embryo samples were frozen and stored at -196 ºC. Frozen embryos (n=35) were randomly extracted for total cellular DNA and amplified by PCR method. DNA samples were stored at -20 ºC. Sexing was determined by modification of LAMP method with either 1mM EB or 1M CS...

Objective of this study was to determine the effect of stair-step feeding regimen during estrous cycle on follicular development and oocytes quality. Sixteen Thai-native non pregnant goats were used with the average age and body weight of 8 months and 17±0.6 kg, respectively. The does exhibited at least 2 normal estrous cycle and were housed in 1 m2 steel cages. Heat detection was daily recorded using a vasectomized buck. The does were randomly assigned into two groups: Control and Stair-step feeding group. In the control group, does were fed 100% of nutrients requirement for growth in puberty periods. Does consumed Ruzi grass hay, DM = 500 g/head/d and concentrate supplemented at 1% of body weight. Total feed intake was 670 g/head/d, (ME = 1.48 Mcal/kg/d,...
