The cleavage rate of in vitro-matured bovine oocytes was compared after fertilization in 1) TALP medium alone (control); 2) in TALP+BOEC; 3) in TALP+PHE; or 4) in TALP+BOEC and PHE. The overall cleavage rate at 45 h post insemination was greater for embryos in Treatments 2 (52%), 3 (55%) and 4 (66%) than for Treatment 1 (32%). The oocyte cleavage rates for(More)
Our objective was to optimize in vitro maturation conditions of bovine oocytes as assessed by embryo development. In Experiment 1, cumulus-oocyte complexes were matured in either M-199 or RPMI-1640. Each medium was supplemented with an antibiotic-antimycotic solution (1%) and estrous cow serum (20%). Cumulus cell expansion after 24 h was greatest for(More)
Thirty Holstein fetuses from 100 to 251 d after conception were utilized to study prenatal anatomical development of the epithelium of the rumen and reticulum. Four calves at birth were included in the study for comparison. Tissue sections were frozen and stained to locate specific enzymes. At 100 d, the epithelial layer of the rumen was differentiated into(More)
This study examined the effects of extending oocyte maturation 4 h beyond current methods and capacitating sperm with or without heparin 4 h before oocyte introduction to determine whether embryo development would increase after in vitro fertilization. Oocytes were aspirated from ovaries that were collected at slaughter. Cumulus-enclosed oocytes were(More)
This paper presents design and evaluation of a decentralized control mechanism of a variable-topology (phase-reconfigurable) multiprocessor architecture. We design and implement an active crossbar communication processor(XCP) which encodes a set of communication instructions. The new interconnection network approach provides an apt phase-reconfiguration(More)
