Dietary excesses of urea influence the viability and metabolism of preimplantation sheep embryos and may affect fetal growth among survivors
252
TL;DR: Excess rumen degradable N in ewe diets elevates urea and ammonia in plasma and in utero, with an associated increase in embryo mortality, Nevertheless, metabolism appears to be up-regulated in some embryos and, among those that survive, fetal growth seems to be enhanced.

Large offspring syndrome in cattle and sheep.
TL;DR: Four different situations have been identified that result in the large offspring syndrome: in vitro embryo culture, asynchronous embryo transfer into an advanced uterine environment, nuclear transfer and maternal exposure to excessively high urea diets.

Maternal undernutrition during the preimplantation period of rat development causes blastocyst abnormalities and programming of postnatal hypertension.
TL;DR: The data indicate that long-term programming of postnatal growth and physiology can be induced irreversibly during the preimplantation period of development by maternal protein undernutrition, and proposes that the mildly hyperglycaemic and amino acid-depleted maternal environment generated by undernutrition may act as an early mechanism of programming and initiate conditions of 'metabolic stress', restricting early embryonic proliferation and the generation of appropriately sized stem-cell lineages.

Fertility in the high-producing dairy cow ☆
TL;DR: To maintain or recover high fertility in modern dairy cows calls for a two-pronged approach involving both inclusion of fertility in broader breeding goals and adjustment to management practices.

Procedures for Detecting Outlying Observations in Samples
TL;DR: In this paper, a procedure for determining statistically whether the highest observation, lowest observation, highest and lowest observations, or more of the observations in the sample are statistical outliers is given.
Successful culture in vitro of sheep and cattle ova
TL;DR: This communication describes the successful culture of one-cell to eight-cell sheep ova and one- cell and eight- cell cattle ova to the morula and blastocyst stages and reports a high embryo survival after transfer of cultured Ova to recipient animals.

Effects of Excess Degradable Protein on Postpartum Reproduction and Energy Balance in Dairy Cattle
TL;DR: Energy balance status plays an important role in determining the postpartum return of cyclic ovarian activity, and feeding excess CP as rumen degradable protein elevated plasma urea concentrations and decreased first service conception rate.
