Time spent feeding by grazing cattle is an important predictor of intake and feed efficiency. This study examined the use of automatic supplement weighing (ASW) units for monitoring voluntary access of breeding cows (n = 430) to mineral block supplem

Rumen protozoa produce hydrogen, which can be utilised by methanogens to produce enteric methane (CH4) that is a loss of digested energy and has an adverse environmental impact as a greenhouse gas. The aim of this study was to examine the effect of t

Effects of rumen protozoa on ruminal fermentation, methane (CH4) emissions and nitrogen (N) retention were studied in twelve crossbred ewes given an oaten chaff diet. Over 10 days sheep were progressively adapted to a diet containing 7% coconut oil d

Melnychuk et al.’s comments in PNAS (1) that successful fisheries management requires the “capacity to limit fishing pressure” and “scientists are generally unanimous in calling for stronger management” echo comments made in many earlier pu

The distribution of trace metals in a ling (Genypterus blacodes) fish fillet was determined from ICP-MS measurements of digests prepared using nitric acid and hydrogen peroxide, followed by microwave digestion. Most trace elements were inhomogeneousl

The concentrations of selected trace metals were measured in commercially harvested New Zealand scallop species: Chlamys delicatula (queen scallop) from the Otago Coastal Shelf and Pecten novaezelandiae (dredge scallop) collected from 6 sites around

A comparison is presented of six methods involving nitric acid in conjunction with other reagents to digest three certified marine biological samples (DOLT-3, DORM-3, IAEA-407) and a fish bone homogenate (prepared from Merluccius australis). An induc

There are recognised benefits to managing fisheries by individual transferable quotas (ITQs), but ITQs may increase incentives to discard fish. Trawl data from government-observed trawlers in the New Zealand hoki fishery were used to predict catches

The contribution of native insects to poor establishment of oversown grasses in subalpine tussock grasslands was explored in a series of small trials on the East Otago Plateau, New Zealand. The maintenance of relatively insect-free conditions by use
