Genetics, nutrition and animal management each have integral roles in maximizing growth efficiency of domestic livestock. Residual feed intake (RFI) is an accurate method of distinguishing between feed efficient and ...

Pig conceptuses produce and secrete estrogens (E[2]), interleukin 1 beta 2 (IL1B2), and prostaglandins (PGs) during the period of rapid trophoblast elongation and establishment of pregnancy. Previous studies established ...

The objective of this study was to determine effects of feeding chestnuts and acorns on growth performance, carcass quality and further processed products of Duroc/Duroc crossbred finishing barrows. Barrows (n = 30) were ...

"The ability to elucidate quantitative trait architecture and introduce potentially beneficial traits makes introgression a useful tool. Unfortunately, due to the nature of inheritance there are certainly limitations to ...

Boars subjected to summertime temperatures results in reductions in sperm quality. This reduction in quality is associated with decreases in both litter size and conception rate. With this study we aim to quantify the ...

Growing concerns with saturated fatty acids on human health has led to research being done to reduce saturated fatty acid levels in animal tissues. The objective of this study was to evaluate the effect of high oleic soybean ...

The recent development of split-time artificial insemination as a breeding strategy improved reproductive outcomes following treatment with the 14d CIDR[copyright]-PG protocol; however, STAI has not been evaluated with ...

Preovulatory secretion of estradiol and postovulatory secretion of progesterone are essential for preparing the uterine environment for pregnancy in cattle. In a previous study, circulating concentrations of preovulatory ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nine experiments were conducted to determine the optimal digestible isoleucine (dIle), valine (dVal), leucine (dLeu), phenylalanine plus tyrosine (dPT) ...

Mice are one of the most commonly used rodent species as a model for biomedical research to better understand molecular, genetic, and cellular causes of human disease and disorders. The production of good quality oocytes ...

The use of somatic cell nuclear transfer (SCNT) to create agricultural and biomedical models is extremely useful for understanding how we can improve the efficiency of production agriculture, as well as how we can better ...

The proposed signal for maternal recognition of pregnancy in pigs is estrogen, produced by the elongating conceptus. To understand the role of estrogen in porcine conceptus elongation and pregnancy establishment, a loss ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Assisted reproductive technologies (ART) refer to a series of fertility treatments used to conceive offspring. ART is used worldwide in humans for ...

We hypothesized that cows with subclinical hypocalcemia at calving would have greater elevations in liver associated biochemical parameters and non-esterified fatty acid (NEFA) concentrations compared to normocalcemic cows. ...

Heat stress caused by high ambient temperatures causes seasonal infertility in sows, leading to decreased production and a loss in reproductive efficiency. The objective of these studies was to specifically determine the ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Artemisia afra (AF) is a herb used by indigenous peoples of South Africa to alleviate heat stress during desert travel, and Artemisia absinthium (AB) ...

Genotype by environment interactions (GxE) may reduce accuracy of sire selection. The objectives of this study were to evaluate the presence of GxE by comparing reaction norms of bulls for birth weight, weaning weight, ...

We designed two continuous culture experiments to test the effects of starch dosage and starvation upon equine fecal microflora. Diets were designed containing fructooligosaccharides and mannanoligosaccharides in order to ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] An experiment was conducted to determine the effects of diets formulated using the ideal protein concept and modeled amino acid requirements with diet ...

Heat stress and fescue toxicosis, resulting from intake of endophyte-infected fescue, have significant impacts on physiological processes in cattle. To study this impact, we used numerous physiological measures of thermal ...
