Heritability estimates for calving date in Simmental cattle
… to have at least 50% Simmental breeding, to have calved first at 2 yr of age and to have been born and subsequently calved in the same herd and season. Traits analyzed included first and second calving dates, first calving interval and the percentage of cows that returned to calve in the same …

Behavioral choices of male humpback whales (Megaptera novaeangliae) on the Hawaiʻian wintering grounds
… warmer waters during the winter months to calve and presumably, though it has never been documented, to mate. The North Pacific has three main wintering grounds: Hawaii, Mexico/California, and Japan (Dawbin, 1966, Darling and Jurasz, 1983; Baker, Herman, Perry, Lawton, Straley, Wolman, …

Comparison of maternal performance of reciprocal crossbred cows
… breeds to produce three-breed and baekcross calvea. Shorthorn x Angus cows (sire breed first) weaned l7.S~ fewer calve. and Hereford x Angus cows 10.31 fewer calves than their respective reciprocal crosses. Thete differencea while large were not statistically significant presumably due to the …

Estimation of heterotic effects on stayability in beef cattle
… in the herd until age six given that she has calved as a heifer. In some breeds with total herd reporting, those cows are required to calve every year. Stayability influences herd profitability by decreasing the need for replacements by increasing the number of cows that reach the typical …

Programmed Feed Intake of High Energy Diets Influences Digestibility and Maintenance Requirements of Beef Cattle
… to exhibit estrus at an adequate age to first calve at 24 months of age. A minimum of 97.5% of the heifers fed on a program fed regime were cyclic for at least one month prior to artificial insemination (P < 0.05). In the third experiment, a metabolism study was used to determine the …

Seafloor ploughmarks on the mid-Norwegian continental shelf reveal iceberg trajectories during the last glacial period
… the existence of thick, multi-keeled ‘megabergs’ calved from the FIS during the last glacial period. The estimated maximum thickness of the FIS and record of large tabular icebergs indicate that, on the mid-Norwegian continental margin, marine ice cliff instability (MICI) – the process by which …

Influence of Prepubertal Dietary Protein and Age at First Calving on the Performance, Reproduction and Lactation of Replacement Beef Heifers
… management systems. Heifers were managed to calve first at 18 or 24 months of age. The effects of prebreeding protein and age at first calving were tested in several prebreeding production settings including normal weaning and creep feeding, early weaning and creep feeding, and early weaning …

Controls on terminus change of marine terminating glaciers in Greenland over the last 40+ years
… and low sinuosity are present at glaciers that calve via buoyant flexure, while the opposite is true at glaciers that are dominated by melt-induced calving via serac failure. I also find that glaciers do not persistently fit into single calving styles and may change over time. By studying how …

Heritability and repeatability estimates of first service conception and first cycle calving in Angus cattle
… due to a reduction in calf crop, lower quality calves, and increased breeding and replacement costs. Improving reproductive efficiency via altered management and selection could prove useful for cattle managers to minimize these costs while increasing genetic gain and income. However, …

The acute and chronic effects of resistance exercise with and without blood flow restriction on fall risk factors in older adults
… resistance programme using the box squat and calve raise exercises to examine a host of quiet standing, gait stability and functional balances tests in addition to neuromuscular, proprioception and indices of strength measured at baseline, mid and post 6-week testing points. The results from …

Innovation adoption and farm management practices in the Canterbury dairy industry
… loss (33%), and synchronising of heifers to calve two weeks before the herd (21%). In general, adoption behaviour in relation to specific FMPs correlated poorly with other FMPs, indicating that each adoption is a specific decision rather than as part of an adoption package. Respondents’ …

Staphylococcus spp. from animals intended for human consumption, animalderived food and humans in Spain and Senegal: genetic lineages, antibioresistance and virulence
… countries with different antibiotic use policy (calve, lamb, goat (Spain); cow and chicken (Senegal)). In Spain, the prevalence of staphylococci was higher in lamb (54%) and goat (50%) than in cow (21%) samples. In Senegal, staphylococci prevalence was higher in cow (26.8%) than in chicken (3%). …

Anestrus, repeat-breeding, dystocia, retained fetal membranes (RFM), endometritis and abortion as the major reproductive problems in dairy cattle in the study area. Serum, milk, …

The wintering and calving of Angus beef cows on a sawdust pad : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University
… In 1969 25 cows from this herd were mated to calve at two-years-of-age. The two herds were run together as one unit during the trial, distinction only being made for the purpose of statistical analysis. The pad consists of two yards with sawdust packed on top of tile drains. A concrete apron …

PREVALENCE, LONGITUDINAL DYNAMICS, AND FACTORS ASSOCIATED WITH THE FAECAL SHEDDING OF EXTENDED-SPECTRUM Β-LACTAMASE-PRODUCING BACTERIA IN ITALIAN NEONATAL DAIRY CALVES
… In dairy production systems, pre-weaned calves are considered important reservoirs of ESBL-producing Enterobacterales, yet information on their occurrence, associated risk factors, environmental distribution, and shedding dynamics remains limited in Italy. This thesis investigated the …

Weightbearing and Activity Restriction Treatments and Quality of Life in Patients with Perthes Disease
BACKGROUND: Weightbearing and activity restrictions are commonly prescribed during the active stages of Perthes disease. These restrictions, ranging from cast or brace treatment with nonweightbearing to full weightbearing with activity restrictions, may have a substantial influence on the physical, …
