New Zealand’s beef industry produces approximately 580,000 tonnes of beef per year, about 80% of which is exported, with approximately 70% of this beef destined for the North American manufacturing market. Around 65% of beef cattle originate from the dairy industry. Beef cows produce 1.1 million calves (killed as heifers or steers) per year for the prime beef market. In addition, 0.4 to 0.6 mil...

Records of 594 calving dates and 493 calving intervals collected from a herd of Retinta beef cows in southwest Spain were studied. Their efficacy as reproductive measures were compared when a long breeding season was utilized. Variables used were date of present calving (DOC), date of subsequent calving (DOSC), time from start of breeding season to calving (TBSC), interval to next calving (CI),...

The objectives of this study were to examine the impact of corn- or wheat-based dried distillers grains with solubles (CDDGS or WDDGS) on enteric methane (CH4) emissions from growing beef cattle and determine if the oil in CDDGS was responsible for any response observed. Effects of CDDGS or WDDGS on total N excretion and partitioning between urine and fecal N were also examined in this replicat...

In a ®eld trial (1985±1996) on a sandy loam soil the effects of tractor traf®c and fertilisation on earthworm populations were investigated. The tractor traf®c treatments compared normal farm practice (`normal') with reduced tractor traf®c (`low'). In the fertilisation treatments, three different cattle-manure management methods were compared. The cattle manure was applied as diluted slurry, as...

objective(s): in recent years, there has been an increasing amount of study on early diagnosis of kidney injury through sensitive and specific biomarkers. we examined the practical applicability of the urinary levels of nag (n-acetyl-β-d-glucosaminidase), ap (alkaline phosphatase), and ldh (lactate dehydrogenase) as renal dysfunction screening biomarkers in full and pre-term newborns treated wi...

background maintenance of the adequate intraoperative renal perfusion is very important during orthotopic liver transplantation (olt) to prevent acute renal failure. objectives for the first time, this study was designed to survey the effects of octreotide on urine output during anesthesia for olt and early postoperative renal function. patients and methods in this randomized double-blind place...

there are several problems associated with the use of indwelling urethra catheters, including urinary tract infections and mechanical problems. infections have been well researched but mechanical problems associated with blockage, leakage of urine and general discomfort have been less investigated. although education of patients and carers on the use of catheters has been recommended, in practi...
