Effects of feed intake and genetics on tissue nitrogen-15 enrichment and feed conversion efficiency in sheep
(Oxford University Press on behalf of the American Society of Animal Science, 2015-12-01)
This study investigated the effects of sheep genetics and feed intake on nitrogen isotopic fractionation (Δ15N) and feed conversion efficiency (FCE; live weight gain/DMI), using a 2 × 2 factorial design, with 2 levels of ...
Variation in the bovine FABP₄ gene affects milk yield and milk protein content in dairy cows
(Scientific Reports, 2015-06-12)
Fatty acid binding proteins (FABPs) bind long-chain fatty acids and are involved in their intracellular transport. Of the known bovine FABP genes, FABP₄ has been mapped to a region on chromosome 14 that contains quantitative ...
Ex-vivo cow rumen fluid fermentation: Changes in microbial populations and fermentation products with different forages
(Taylor & Francis, 2018-07-09)
This study investigated the effects of three forage treatments [herbal plantain (PL), ryegrass-white clover pasture (RW) and root crop fodder beet (FB)] on ex-vivo rumen fluid fermentations. Quantitative real-time Polymerase ...
Nitrogen uptake of 16 grass species under high N loading
(Lincoln University, 2011-09-26)
A study to quantify and examine the variability in N uptake capacities of 16 pasture grass species under high N loading.
Pasture composition and production from different cropping sequences in dryland pasture converted from Pinus radiata forest
(New Zealand Grassland Association., 2007)
Dry matter production and pasture composition were measured over 22 months in eight cropping sequences on a dryland site converted from forest to pasture. Cropping sequences involved different combinations of: (i) autumn ...
The effects of dietary nitrogen to water-soluble carbohydrate ratio on isotopic fractionation and partitioning of nitrogen in non-lactating sheep
(Cambridge University Press (CUP) on behalf of the Animal Consortium, 2013-08)
The main objective of this study was to investigate the relationship between partitioning and isotopic fractionation of nitrogen (N) in sheep consuming diets with varying ratios of N to water-soluble carbohydrate (WSC). ...
Production and composition of nil and MAX P™ tall fescue pastures on dry, stony soils.
(Lincoln University, 2007)
The objective of the study was to determine the effect of tall fescue endophyte AR542 (MAX P™) on dryland pasture production and composition, weed invasion, and sheep gazing preference in Canterbury, New Zealand
Effect of ewe stocking rate in spring on subterranean clover persistence and lamb liveweight gain
(New Zealand Grassland Association., 2006)
Liveweight gain of ewes and lambs and subterranean clover reproduction were measured in tall fescuesubterranean clover pastures on a dry, stony soil stocked at 10 (low) and 20 (high) ewes and their twin lambs/ha over 46 ...
Effects of MaxP™ endophyte in tall fescue on pasture production and sheep grazing preference, in a dryland environment
(New Zealand Grassland Association, 2007)
Pasture growth, botanical composition and sheep grazing preference were measured over 20 months in tall fescue (cultivar Advance), without endophyte (Nil) or infected with AR542 (MaxPTM) endophyte, and clover pastures sown ...
Next generation systems; A framework for prioritising innovation
Primary production industries are constantly changing in response to external factors such as new market opportunities, consumer demands, changing community expectations of the social and environmental outcomes associated ...
