This paper reviews current production trends for sheep and beef cattle production in New Zealand and gives some insight into the opportunities for improvement. The New Zealand climate favours pasture growth and this is the key to sheep and beef cattle production with over 95% of the diet being grazed pasture or crop. Exports are the focus of the industry with 92% of sheep meat and 82% of beef e...

Genetic Evaluation of Body Weight American Simmental Beef Cattle using Single-Step GBLUP Approaches

Of the 1673 cattle tested, 249 (14.9%) were seropositive for N caninum. The mean seroprevalence of individual properties was 14.7% (SD = 8.6%). Of the 40 properties surveyed, only two (5%) did not have a seropositive animal among those tested. Age-related seroprevalence rates are illustrated in Figure 1 and show a seroprevalence of around 10% in heifers with a trend of increasing seroprevalence...

this study highlights the costs and benefits of indigenous beef cattle fattening schemes in shinyanga urban and kishapu districts in tanzania. specifically, in this study the net profit (np) for fatteners between beef cattle fattening schemes has been determined. the schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (cshl) based diets and ...

In 2008-2010, samples of meat from 40 beef cattle, along with grass, soil and commercial feed, taken from ten matched pairs of flood-prone and control farms, were analysed for PCDD/Fs and PCBs. Concentrations were higher in soil and grass from flood-prone farms. The beef samples from flood-prone farms had total TEQ levels about 20% higher than on control farms. A majority of flood-prone farms (...

It is extremely difficult for the Hawai‘i beef industry to compete against the concentrate-finished beef that dominates the U.S. beef industry because of our state’s lack of grain production, lack of economy of scale, and an inefficient processing segment. Nevertheless, produc­ ers continue to keep their faith in the local and emerg­ ing niche markets, looking for opportunities for mar­ keting ...

Growth-promoting implants offer beef cattle producers a safe and effective way to increase calf weight gains. Implants increase production of muscle tissue and often reduce body fat production. This results in significant improvements in both growth rate and feed efficiency. Despite the proven benefits of implant use, only 11.9 percent of beef cattle operations surveyed by the National Animal H...

Synchronization of estrus contributes to optimizing the use of time, labor, and financial resources by shortening the calving season, in addition to increasing the uniformity of the calf crop. The major limitation of estrus-synchronization programs is their inability to induce a potentially fertile estrus and ovulation in noncycling cattle (i.e., prepubertal heifers and anestrous suckling cattl...

BACKGROUND Human intestinal sarcocystosis is a zoonotic disease caused by two coccidians, i.e. Sarcocystis fusiformis (syn. S. bovihominis, S. hominis) due to consumption of raw infected beef and Sarcocystis meischeriana (syn. S. suihominis) due to consumption of infected raw pork. In 1987, survey of the macroscopic S. fusiformis cysts in market beef mainly from old water buffalos aged more tha...
