Effects of overnutrition and undernutrition on in vitro fertilization (IVF) and early embryonic development in sheep
Nutrition has been shown to influence several reproductive functions including hormone production, oocyte competence and fertilization, and early embryonic development. To determine effects of maternal diet on in vitro fertilization (IVF) and early embryonic development, ewes (n = 48; 58.4 ± 1.7 kg initial body weight [BW]; 2.3 ± 0.1 initial body condition score [BCS]) were divided into control...
متن کاملA Preliminary Report on Early Embryonic Development Following Oocyte Vitrification and In Vitro Fertilization in Sheep
Interest in oocyte cryopreservation has recently increased with the growing importance of in vitro embryo production, nuclear transfer, and gene banking (Gordon, 1997; Andrus et al., 2000). A relatively recent approach to achieve rapid freezing without the use of expensive freezing devices is called vitrification. Vitrification is defined as the physical process by which a highly concentrated s...
متن کاملEffects of Undernutrition on in Vitro Fertilization (ivf) and Early Embryonic Development in Sheep
Nutrition has been shown to influence several reproductive functions including hormone production, oocyte competence and fertilization, and early embryonic development. To determine the effects of maternal diet on in vitro fertilization (IVF) and early embryonic development, ewes (n=18) were divided into control and underfed groups and received 100% and 60% maintenance diet, respectively, for 8...
متن کاملCHANGES IN NUCLEAR HISTONES DURING FERTILIZATION, AND EARLY EMBRYONIC DEVELOPMENT IN THE PULMONATE SNAIL, Helix aspersa
Calf thymus histories comprising two fractions, one rich in lysine, the other having roughly equal amounts of lysine and arginine, Loligo testes histones rich in arginine, and salmine, are compared with respect to their amino acid compositions, and their staining properties when the proteins are fixed on filter paper. The three types of basic proteins; somatic, arginine-rich spermatid histones,...
متن کاملFertilization rate and early embryonic loss in Brahman crossbred heifers.
The fertilization rate and incidence of embryonic loss in virgin Brahman crossbred heifers between d 3 and 35 postinsemination (d 0 = first day of estrus) were determined. One hundred fifty-five virgin heifers, maintained in a dry lot, received approximately 22 Mcal.head-1.d-1 and were allotted to one of three groups (d 3, 16 or 35) according to body weight at the time of estrous detection. Sev...
