Nutrient recycling: The North American experience - Review
(1999-06)Options available for utilization of animal wastes include sources of plant nutrients, feed ingredients for farm animals, substrate for methane generation, and substrate for microbial and insect protein synthesis. The ... -
Estimation of additive, dominance and epistatic variance components using finite locus models implemented with a single-site Gibbs and a descent graph sampler
(Cambridge University Press, 2000-10)In a previous contribution, we implemented a finite locus model (FLM) for estimating additive and dominance genetic variances via a Bayesian method and a single-site Gibbs sampler. We observed a dependency of dominance ... -

Virginia 4-H Ewe Flock Project Guide
(Virginia Cooperative Extension, 2001)A project designed to assist the 4-H member in developing characteristics of responsibility and sound decision-making while acquainting them with general care and maintenance of a sheep flock. -
Bayesian QTL mapping using skewed Student-tdistributions
(2002-01-15)In most QTL mapping studies, phenotypes are assumed to follow normal distributions. Deviations from this assumption may lead to detection of false positive QTL. To improve the robustness of Bayesian QTL mapping methods, ... -
Effects of load type (pollen or nectar) and load mass on hovering metabolic rate and mechanical power output in the honey bee Apis mellifera
(2003)In this study we tested the effect of pollen and nectar loading on metabolic rate (in mW) and wingbeat frequency during hovering, and also examined the effect of pollen loading on wing kinematics and mechanical power output. ... -
Digestion and nitrogen utilization by sheep fed diets supplemented with processed broiler litter
(2003-11)In vivo digestion and metabolism trials were conducted with 10 wethers equipped with ruminal, abomasal, and ileal cannulae to evaluate digestion of ensiled broiler litter (EBL), deepstacked broiler litter (DBL), and composted ... -
Effects of dietary cis 9, trans 11-18 : 2, trans 10, cis 12-18 : 2 or vaccenic acid (trans 11-18 : 1) during lactation on body composition, tissue fatty acid profiles, and litter growth in mice
(Cambridge University Press, 2003-12)Cis 9, trans 11 (c9, t11)-18:2 and trans 10, cis 12 (t10, c12)-18:2 are the major conjugated linoleic acid (CLA) isomers in dietary supplements which reduce milk fat content in nursing women. The present study evaluated ... -
Dietary phosphorus effects on characteristics of mechanically separated dairy manure
(American Society of Agricultural and Biological Engineers, 2005)One approach to reduce nutrient losses from livestock farms is to apply biological waste treatment systems such as biological nitrogen (N) removal or enhanced biological phosphorus (P) removal (EBPR) to reduce the nutrient ... -
Poultry genomics puts meat on the table.
(2005)Why did the chicken cross the road, you ask? Because the draft sequence of its genome has been released, silly. So, along with other ‘bird enthusiasts’ and advocates, those long involved in chicken genetics and genetic ... -
Characterization of Expressed Sequence Tags From a Gallus gallus Pineal Gland cDNA Library
(Hindawi, 2005-01-01)The pineal gland is the circadian oscillator in the chicken, regulating diversefunctions ranging from egg laying to feeding. Here, we describe the isolation andcharacterization of expressed sequence tags (ESTs) isolated ... -
Genistein activates the 3 ',5 '-cyclic adenosine monophosphate signaling pathway in vascular endothelial cells and protects endothelial barrier function
(Endocrine Society, 2005-03)The soy phytoestrogen, genistein, has an array of biological actions, including weak estrogenic effects, inhibition of tyrosine kinase, and cellular antioxidant activity. Recent studies showed that genistein may improve ... -
Understanding Expected Progeny Differences (EPDs)
(Virginia Cooperative Extension, 2005-09-01)Expected progeny differences (EPDs) provide estimates of the genetic value of an animal as a parent, and should be given careful attention when choosing bulls. -
Cattle Identification: Freeze Branding
(Virginia Cooperative Extension, 2005-09-01)Freeze branding offers a permanent form of individual animal identification that is easy to read at a great distance, causes minimal damage to the hide, and is less painful than hot branding. -
Beef Cattle Breeds and Biological Types
(Virginia Cooperative Extension, 2005-09-01)There are more than 250 breeds of beef cattle. The breed, or combination of breeds, used in a defined breeding program have a significant impact on the efficiency and profitability of the beef enterprise. -
Crossbreeding Beef Cattle
(Virginia Cooperative Extension, 2005-09-01)A well-designed, manageable crossbreeding system is an important aspect in making genetic progress in the various economically important traits that drive profitability in today's beef industry. -
Virginia Cow Herd Performance Check-Up
(Virginia Cooperative Extension, 2005-09-01)An annual analysis of various herd performance measures can serve as a yardstick against which to compare past and future years' performance. -
Use of N-alkanes to estimate intake and digestibility by beef steers
(2005-11)The objective of the study was to evaluate the use of n-alkanes to estimate DM intake and digestibility by beef cattle. Six steers were blocked (3 blocks, 2 animals/block) according to the body weight (279 +/- 19 kg) and ... -
Opportunities for detection and use of QTL influencing seasonal reproduction in sheep: a review
(2005-12-15)Genetic improvement in traits associated with seasonal breeding in sheep is challenging because these traits have low heritabilities, are generally not expressed until late in life, are commonly recorded only in females, ...
