Effects of two forms of intrareticular selenium supplements on beef cow selenium status and on the transfer of selenium from dam to offspring

Creator:: Campbell, Donald T.
Abstract:: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum...

Relationships between hemoglobin genotype and production in cross-bred ewes. I. Reproduction and lamb production : II. Wool and milk production and health related traits

Creator:: Dally, Martin R.
Abstract:: I. REPRODUCTION AND LAMB PRODUCTION Relationships among hemoglobin (Hb) genotypes and reproduction and production traits were examined in 294 four- and five-year-old North Country Cheviot, Dorset, Finnsheep or Romney x Suffolk or Columbia-type crossbred ewes. Hb BB ewe lambs were youngest at first estrus and Hb AA ewe lambs were...

The relationship of estradiol to embryo-maternal interactions in the llama

Creator:: Powell, Susan A.
Abstract:: In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...

Nutrition and management of the beef unit for production of slaughter animals on range and improved pastures in southeastern Oregon

Creator:: Daugherty, Dennis A.
Abstract:: Studies were conducted over a two year period to evaluate alternative finishing methods for spring and fall-born beef cattle. Management alternatives from birth to slaughter included season of calving, lactating cow nutrition, preweaning calf nutrition, weaning age, calf and yearling winter nutrition, range and irrigated pasture supplementation, grazing practice, range...

Plasma membrane composition and luteinizing hormone receptors of ovine corpora lutea during early pregnancy

Creator:: Zelinski, Mary Beth
Abstract:: The lipid composition of plasma membranes of corpora lutea was examined to determine whether changes in this organelle occur during regression and early pregnancy in the ewe. Forty ewes were assigned to be necropsied on days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or pregnancy (D13-P and...

Selection for hybrid female reproductive performance in the mouse

Creator:: Chapman, Verne Merrill
Abstract:: The design of this study was suggested by the following observations: (1) the successful application of recurrent selection techniques in obtaining improvement of hybrid performance in corn and Drosophila, (2) the increased production realized by rotational crossbreeding, and (3) the expression of a relatively large degree of hybrid vigor in...

The effects of various levels of dietary protein on high producing dairy cows in early lactation

Creator:: Pangborn, Marvin Clark
Abstract:: This project was designed to test the biological effects of three levels of dietary protein (12.7, 16.3 and 19.3% CP on a dry matter basis) on high producing Holstein-Friesian dairy cows. Forty five second lactation or older cows that showed the potential to produce over 31.75 kg (70 lbs) per...

Postpartum disorders associated with high potassium forages in Holstein cows

Creator:: Crill, Roberta L.
Abstract:: Until recently, occurrence of milk fever (MF) has been attributed to prepartum calcium intake. However, researchers in Iowa have concluded that high prepartum dietary potassium (K) is the major cause of MF. Potassium concentrations have been increasing on manure fertilized soils over the last 20 years. Grasses grown on these...
