In contrast to European countries, the overwhelming majority of dogs in the U.S. are neutered (including spaying), usually done before one year of age. Given the importance of gonadal hormones in growth and development, this cultural contrast invites an analysis of the multiple organ systems that may be adversely affected by neutering. Using a single breed-specific dataset, the objective was to examine the variables of gender and age at the time of neutering versus leaving dogs gonadally intact, on all diseases occurring with sufficient frequency for statistical analyses. Given its popularity and vulnerability to various cancers and joint disorders, the …

Microtubule transport of herpesvirus capsids from the cell periphery to the nucleus is imperative for viral replication and, in the case of many alphaherpesviruses, transmission into the nervous system. Using the neuroinvasive herpesvirus, pseudorabies virus (PRV), we show that the viral protein 1/2 (VP1/2) tegument protein associates with the dynein/dynactin microtubule motor complex and promotes retrograde microtubule transport of PRV capsids. Functional activation of VP1/2 requires binding to the capsid protein pUL25 or removal of the capsid-binding domain. A proline-rich sequence within VP1/2 is required for the efficient interaction with the dynein/ dynactin microtubule motor complex as well as for …

Mature mammalian sperm contain a complex population of RNAs some of which might regulate spermatogenesis while others probably play a role in fertilization and early development. Due to this limited knowledge, the biological functions of sperm RNAs remain enigmatic. Here we report the first characterization of the global transcriptome of the sperm of fertile stallions. The findings improved understanding of the biological significance of sperm RNAs which in turn will allow the discovery of sperm-based biomarkers for stallion fertility. The stallion sperm transcriptome was interrogated by analyzing sperm and testes RNA on a 21,000-element equine whole-genome oligoarray and by RNA-seq. …

Of the Orthomyxoviridae family of viruses, only influenza A viruses are thought to exist as multiple subtypes and has nonhuman maintenance hosts. In April 2011, nasal swabs were collected for virus isolation from pigs exhibiting influenza-like illness. Subsequent electron microscopic, biochemical, and genetic studies identified an orthomyxovirus with seven RNA segments exhibiting approximately 50% overall amino acid identity to human influenza C virus. Based on its genetic organizational similarities to influenza C viruses this virus has been provisionally designated C/Oklahoma/1334/2011 (C/OK). Phylogenetic analysis of the predicted viral proteins found that the divergence between C/OK and human influenza C viruses was …

A 1.5-year-old second-parity Large Black X Tamworth cross sow from a well-managed 20-sow, unvaccinated, pasture-raised herd of pigs in upstate New York aborted a litter of 7 variably mummified near-term fetuses and stillborn piglets. This sow had no signs of ill health other than abortion; it was housed in a group with 4 other sows and a 2-year-old Gloucestershire Old Spot boar. One of the stillborn piglets from this litter was submitted to the New York State Animal Health Diagnostic Center for necropsy; no placental tissue was submitted with the piglet. A second sow from this group had aborted a …

Horses were domesticated from the Eurasian steppes 5,000-6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F(ST) calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely reflect …

Intense selective pressures applied over short evolutionary time have resulted in homogeneity within, but substantial variation among, horse breeds. Utilizing this population structure, 744 individuals from 33 breeds, and a 54,000 SNP genotyping array, breed-specific targets of selection were identified using an F(ST)-based statistic calculated in 500-kb windows across the genome. A 5.5-Mb region of ECA18, in which the myostatin (MSTN) gene was centered, contained the highest signature of selection in both the Paint and Quarter Horse. Gene sequencing and histological analysis of gluteal muscle biopsies showed a promoter variant and intronic SNP of MSTN were each significantly associated with …

Effects Of Housing System, Slaughter Age, And Sex On Slaughter And Carcass Traits Of Native Turkish Ducks, Mehmet Sari, Kadi̇r Önk, Serpi̇l Işik, Muammer Ti̇lki̇, Tuncay Tufan
Turkish Journal of Veterinary & Animal Sciences
The purpose of this study was to determine the effects of different housing systems, slaughter age, and sex on slaughter and carcass traits of native Turkish ducks. A total of 133 ducklings were used. One-day-old ducklings were divided into 2 housing groups, a cage system and a deep litter floor system, under uniform conditions. Housing system significantly affected hot carcass, cold carcass, breast, wing, neck, and back percentages (P < 0.05, P < 0.01, and P < 0.001). The results of the current study showed the influence of housing system, sex, and slaughter age on slaughter and carcass traits. The slaughter and carcass traits and feed conversion efficiency were higher in the deep litter floor system than in the cage system for native Turkish ducks. The slaughter and carcass traits of male ducks were higher than those of female ducks. The ideal slaughter weight for native Turkish ducks was reached at 8 weeks, whereas the results for hot carcass weight, cold carcass weight, hot carcass percentage, and cold carcass percentage were better at 10 weeks of age. Therefore, it seems most appropriate to slaughter native Turkish ducks at 10 weeks of age.

Nebraska Beef Cattle Reports
This study evaluated the effect of post-weaning development system on heifer ADG, reproductive performance, and subsequent feed efficiency as a pregnant heifer. Heifers were developed on dormant pasture and grazed corn residue or dormant pasture and placed in a drylot. The following winter, a subset of pregnant heifers were placed in a Calan Broadbent individual feeding system during late gestation. Drylot-developed heifers had greater BW from pre-breeding through pregnancy diagnosis and greater overall ADG during development. However, there was no difference in reproductive performance. Pre-calving BW, ADG, and G:F tended to be greater for drylot heifers. Heifers developed on corn …

Heifers With Low Antral Follicle Counts Have Low Birth Weights And Produce Progeny With Low Birth Weights, Adam F. Summers, Robert A. Cushman, Karl Moline Moline, Jeff Bergman, Andrea S. Cupp
Nebraska Beef Cattle Reports
To determine the relationship of antral follicle count and heifer BW, reproductive tract characteristics, and first-calf performance, Red Angus-composite heifers were used over three years. High antral follicle count heifers had greater BW from birth through pre-breeding. Progeny birth BW was greater for calves born to high antral follicle count heifers compared to low antral follicle count heifers. Taken together these data indicate a relationship between antral follicle counts and BW through the first breeding season and corresponding progeny, and continues to support a possible link between genes that influence growth and development and establishment of ovarian reserve.

The objective of this experiment was to determine the effectiveness of fixed-time AI utilizing one of two estrus synchronization protocols, CO-Synch or CO-Synch + CIDR, in May-calving cows. Cows synchronized with the CO-Synch + CIDR protocol had increased AI and overall pregnancy rates compared to cows synchronized utilizing the CO-Synch protocol. Due to increased AI pregnancy rates, CO-Synch + CIDR cows calved earlier, resulting in a greater proportion of cows calving within the first 21 days of the calving season compared to CO-Synch cows.

Nebraska Beef Cattle Reports
DNA samples from 25 newborn calves taken via hair, ear notch, and nasal swabs were used to determine the efficacy of sampling method in assigning parentage. Nasal swab samples were collected at six time points from birth to 120 hours post-birth. Calf samples and all candidate sires were genotyped with a 99 SNP parentage panel. Nasal swab collection time did not result in significant differences in the ability to assign the correct sire, although differences were seen in apparent cleanliness of the sample. Clean nasal swab samples are comparable in efficacy to hair and ear notch samples in assigning parentage.

Two experiments evaluated the feeding value of grass hay bales previously treated with CCDS in growing cattle diets. In Experiment 1, heifers fed bales treated with 20% CCDS (DM) gained less than those fed an equal level of dried distillers grains plus solubles and nontreated hay. In Experiment 2, ADG and F:G linearly improved with increasing CCDS levels. Furthermore, supplementing cattle to meet metabolizable protein requirements when fed diets of CCDS and hay did not improve ADG at levels greater than 15% CCDS. Data indicate hay bales previously treated with CCDS are adequate for use in growing diets, confirming that …

A grazing study was conducted to determineif field peas are a good naturalbinder for dried distillers grains-based range cubes. Cattle supplemented dried distillers grains in the bunk or a 25% field pea/75% distillers grains cube fed on the ground gained similarly and outgained cattle supplemented dried distillers on the ground. A 25.6% loss of the distillers grains fed loose on the ground was estimated. The similar performance of cattle fed distillers grains in the bunk and those fed pea/distillers cube on the ground suggests field peas reduced distillers grains loss and therefore are an acceptable binder for distillers grains based …

Economic Analysis Update: Supplementing Distillers Grains To Grazing Yearling Steers, Stephanie K. Moore, Andrea K. Watson, Terry Klopfenstein Klopfenstein, Galen E. Erickson, Walter H. Schacht
Nebraska Beef Cattle Reports
A seven-year study from 2005-2011 was conducted to evaluate four grazing management strategies for backgrounding yearling steers on smooth bromegrass pastures. Economic budgets were used to calculate profit differences with current (April 2012) market prices. Overall, cattle receiving supplement had greater net returns, lower cost of gain, and lower breakeven prices. In recent years fertilizer prices have increased at a greater rate than land costs in Nebraska, making it more economical to use a lower stocking rate instead of fertilizing pastures. As land prices increase, the incentive to use either N fertilizer or DDGS supplementation increases.
