Animal Performance And Diet Quality While Grazing Corn Residue, Jennifer A. Gigax

Department of Animal Science: Dissertations, Theses, and Student Research

Grazing cattle on corn residue as a winter feed source has become an integral part of many Nebraska producers’ management plans. Utilizing corn residues extends the grazing season and is often more economical than grazing winter range or dry lot situations. Corn residue is high in OM and NDF, moderate in digestibility, and low in CP. Cattle grazing corn residues may need to be supplemented with a protein source to meet requirements. The development and application of DNA technology to create new corn hybrids has improved yields with fewer inputs, leading to a continued low cost food supply for consumers. …

Functional Analysis And Post-Transcriptional Regulation Of Oocyte-Specific Transcription Factors During Early Embryogenesis In Cattle, Swamy Krishna Tripurani

Graduate Theses, Dissertations, and Problem Reports (ETD)

Newborn ovary homeobox (NOBOX) is an oocyte-specific transcription factor essential for folliculogenesis and expression of many germ-cell specific genes in mice. However, the temporal and cell specific expression of NOBOX in bovine oocytes and potential function and regulation of NOBOX in early embryogenesis have not been described previously. Messenger RNA for bovine NOBOX is preferentially expressed in ovaries and undetectable by RT-PCR in somatic tissues examined. NOBOX protein is present in oocytes throughout folliculogenesis and is stage-specifically expressed during oocyte maturation and early embryonic development. Depletion of NOBOX in early embryos demonstrated that NOBOX is an essential maternal derived transcription …

Effect Of Service Sire On Late Embryonic And Fetal Loss In Sheep, Tammy L. Holler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Very few authors have studied the effect of the sire on the outcome of pregnancy in sheep beyond differentiation, development, spermatogenesis, fertilization and early embryo survival. A major limitation in direct selection for increased sire competence is that males need to be selected mainly on the performance of their female relatives and females do not express lambing traits until at least one or two years of age. This selection process can be accelerated by studying prenatal survival ability of individual ram's progeny.;The objective of the present study was to identify occurrence of late embryonic and fetal mortality in relation to …
