Specific genotypes of plantain (Plantago lanceolata) vary in their impact on sheep urine volume and nitrification in the urine patch
(New Zealand Grassland Association, 2018-11-13)
Plantain has the potential to reduce nitrate leaching through a number of mechanisms. In an indoor study, sheep were offered either perennial ryegrass or different plantain genotypes while aiming to achieve similar dry ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
In vitro fermentation characteristics of ryegrass-white clover sward containing different proportions of chicory
(New Zealand Society of Animal Production, 2017)
Chicory (Cichorum intybus) is a deep-rooted grazeable forage used to overcome production and nutritive value shortfalls of perennial ryegrass (Loliun perenne) and white clover (Trifolium repens) swards during summer drought ...
Brief communication: Urinary nitrogen excretion and water balance of dairy heifers fed cut plantain or perennial-ryegrass pastures
(New Zealand Society of Animal Production (Inc), 2019)
The objective of our study was to quantify the effect of feeding plantain (PL) or perennial ryegrass (RG) to dairy heifers on urinary nitrogen (N) excretion and water balance. In an indoor cut-and-carry system, four Jersey ...
Dietary preference of dairy cows for perennial ryegrass cultivars growing with and without white clover
(New Zealand Society of Animal Production, 2016)
Dietary preference of dairy cows for eight perennial ryegrass cultivars (AberMagic, Alto, Base, Bealey, Commando, Kamo, One50 and Prospect) growing with and without white clover was examined at two vegetative stages (May ...
Urinary nitrogen concentration from dairy heifers grazing kale supplemented with either plantain or perennial ryegrass baleage in winter
(NZ Grassland Association, 2016)
The effect of feeding two different supplements (perennial ryegrass or plantain baleage) on urinary nitrogen (N) excretion from dairy heifers (8 months old, 180 kg liveweight (LW)) grazing kale was examined in two successive ...
Dry matter intake and body condition score change of dairy cows grazing fodder beet, kale and kale-oat forage systems in winter
(NZGA, 2014)
Crop dry matter (DM) yield, DM utilisation and body condition score (BCS) of dairy cows were measured over two winters on an irrigated stony, free-draining Balmoral soil for three crop grazing systems: fodder beet (FB); ...
Urine volume of non-lactating dairy cows in late gestation fed forage based diets in winter
(New Zealand Society of Animal Production (Inc), 2016)
Quantitative information on urine volume of dairy cows fed winter forages is required to accurately evaluate nitrate leaching risks on these diets. Thirty-two Friesian x Jersey non-lactating, pregnant dairy cows were fed ...
Does mowing before grazing increase dry matter intake and milk yield?
(New Zealand Society of Animal Production, 2016)
Mowing pasture before allocation of herbage to dairy cows is one management strategy suggested to improve feed quality, increase herbage dry matter (DM) intake and increase milk solids yield. To test these hypotheses, ...
Technical note: Nitrogen isotopic fractionation can be used to predict nitrogen-use efficiency in dairy cows fed temperate pasture
(Oxford University Press on behalf of the American Society of Animal Science, 2013-12)
The objective of this study was to investigate the relationship between nitrogen isotopic fractionation (δ¹⁵N) and nitrogen-use efficiency (milk nitrogen/nitrogen intake; NUE) in pasture-fed dairy cows supplemented with ...
