Deciphering Cattle Temperament Measures Derived From a Four-Platform Standing Scale Using Genetic Factor Analytic Modeling
(2020-06-12)The animal's reaction to human handling (i.e., temperament) is critical for work safety, productivity, and welfare. Subjective phenotyping methods have been traditionally used in beef cattle production. Even so, subjective ... -
Haplotype Purging after Relaxation of Selection in Lines of Chickens That Had Undergone Long-Term Selection for High and Low Body Weight
(MDPI, 2020-06-08)Bi-directional selection for increased and decreased 56-day body weights (BW56) has been applied to two lines of White Plymouth Rock chickens—the Virginia high (HWS) and low (LWS) body weight lines. Correlated responses ... -
Characterization of the transcriptional divergence between the subspecies of cultivated rice (Oryza sativa)
(2020-06-08)Abstract Background Cultivated rice consists of two subspecies, Indica and Japonica, that exhibit well-characterized differences at the morphological and genetic levels. However, the differences between these subspecies ... -
Divergent phenotypic response of rice accessions to transient heat stress during early seed development
(2020-01-12)Increasing global surface temperatures is posing a major food security challenge. Part of the solution to address this problem is to improve crop heat resilience, especially during grain development, along with agronomic ... -
Early-Life Stress Induced Epigenetic Changes of Corticotropin-Releasing Factor Gene in Anorexic Low Body Weight–Selected Chicks
(MDPI, 2020-04-27)The expression of neuropeptide Y (NPY) in the arcuate nucleus (ARC) and corticotropin-releasing factor (CRF) in the paraventricular nucleus (PVN) were increased when low body weight–selected (LWS) line ... -
Functional characterization of the turkey macrophage migration inhibitory factor
(2016-08)Macrophage migration inhibitory factor (MIF) is a soluble protein that inhibits the random migration of macrophages and plays a pivotal immunoregulatory function in innate and adaptive immunity. The aim of this study was ... -
Identification and expression analysis of duck interleukin-17D in Riemerella anatipestifer infection
(2016-08)Interleukin (IL)-17D is a proinfiammatory cytokine with currently largely unknown biological functions. Here we provide the description of the sequence, bioactivity, and mRNA expression profile of duck IL-17D homologue. A ... -
Factors affecting fecal egg counts in periparturient Katahdin ewes and their lambs
(2017-01)Selection for low fecal egg counts (FEC) can be used to genetically enhance resistance to gastrointestinal nematode parasites in growing lambs, thereby reducing the frequency of use of anthelmintics, facilitating marketing ... -
Association between FAMACHA scores and fecal egg counts in Katahdin lambs
(2017-03)The FAMACHA system was introduced to the U.S. just over 10 yr ago to allow selective deworming of lambs with anemia associated with Haemonchus contortus and retard the development of anthelmintic resistance. The FAMACHA ... -
Bovine trophectoderm cells induced from bovine fibroblasts with induced pluripotent stem cell reprogramming factors
(2017-06)Thirteen independent induced bovine trophectroderm (iBT) cell lines were established by reprogramming bovine fetal liver-derived fibroblasts after viral-vector transduction with either six or eight factors, including POU5F1 ... -
Expression of host defense peptides in the intestine of Eimeria-challenged chickens
(2017-07)Avian coccidiosis is caused by the intracellular protozoan Eimeria, which produces intestinal lesions leading to weight gain depression. Current control methods include vaccination and anticoccidial drugs. An alternative ... -
Variance components for direct and maternal effects on body weights of Katahdin lambs
(2017-08)The aim of this study was to estimate genetic parameters for BW in Katahdin lambs. Six animal models were used to study direct and maternal effects on birth weight (BWT), weaning weight (WWT), and postweaning weight (PWWT) ... -
Evaluation of Rambouillet, Polypay, and Romanov-White Dorper x Rambouillet ewes mated to terminal sires in an extensive rangeland production system: Lamb production
(2017-09)Ewe productivity (i. e., total number or weight of lambs weaned per breeding ewe) is a key indicator of lamb production efficiency. This study compared various measures of ewe productivity and ewe and lamb performance among ... -
Expression of nutrient transporters and host defense peptides in Campylobacter challenged broilers
(2018-10)Campylobacter is a bacterium that colonizes the lower gastrointestinal tract of poultry and may influence the intestinal environment to promote its survival. The objective of this study was to characterize the effects of ... -
Intermittent bolus feeding promotes greater lean growth than continuous feeding in a neonatal piglet model
(2018-10)Background: Orogastric tube feeding is indicated in neonates with an impaired ability to ingest food normally and can be administered with an intermittent bolus or continuous feeding schedule. Objectives: The objectives ... -
Effects of rearing triplet lambs on ewe productivity, lamb survival and performance, and future ewe performance
(2018-12)Increasing prolificacy has been proposed to be the most effective way to increase the biological efficiency and profitability of sheep production. However, use of prolific breeds and genes with major effects on ovulation ... -
Differential expression of intestinal nutrient transporters and host defense peptides in Eimeria maxima-infected Fayoumi and Ross chickens
(2018-12)Fayoumi chickens are believed to be more disease resistant compared to commercial broiler chickens. The objective of this study was to compare mRNA expression of intestinal nutrient transporters, digestive enzymes, and ... -
Hair sheep performance in a mid-stage deciduous Appalachian silvopasture
(2019-02)Silvopastoral management has potential to diversify and increase the output from livestock systems. Silvopastures offer solutions to many management issues associated with grazing systems in Appalachia (USA). Several tree ... -
Euthanasia: Manual versus Mechanical Cervical Dislocation for Broilers
(2019-02)Simple Summary Poultry are euthanized for several reasons, most commonly because a bird is sick or injured and unable to eat or drink. Euthanasia can be a challenge to perform, especially when birds are heavy, like broiler ... -
Modeling missing pedigree in single-step genomic BLUP
(2019-03)The objective was to compare methods of modeling missing pedigree in single-step genomic BLUP (ssGBLUP). Options for modeling missing pedigree included ignoring the missing pedigree, unknown parent groups (UPG) based on A ...
