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 ...
Brief Communication: Effect of maternal diet in late gestation on development of dairy calves
(New Zealand Society of Animal Production (Inc), 2018)
To investigate whether feeding strategies to reduce urinary N excretion would have negative effects on calf development, two feeding systems were compared. A total of 190 pregnant, Friesian × Jersey dairy cows were randomly ...
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 ...
Relationship between social dominance and milk production of dairy cows grazing pasture
(New Zealand Society of Animal Production, 2016-06)
The objectives of this experiment were to study factors determining social dominance of grazing dairy cows and the relationship between social dominance and milk production under grazing systems. A total of 252 spring ...
Supplementation of spring pasture with harvested fodder beet bulb alters rumen fermentation and increases risk of subacute ruminal acidosis during early lactation
(MDPI, 2020-08)
In a cross-over design, eight rumen cannulated dairy cows were used to explore the industry-recommended method for dietary transition to fodder beet (FB: Beta vulgaris L.) on changes to rumen fermentation and pH, milk ...
Milk production and milk fatty acid composition of grazing dairy cows supplemented with fodder beet
(New Zealand Society of Animal Production (Inc), 2018)
A study was conducted to evaluate the effect of supplementing a perennial ryegrass-based diet with fodder beet on milk production and milk fatty acid (FA) composition, of dairy cows in early lactation. Sixty Friesian × ...
Plantain: It is not only the dietary content, but also how we graze it…
(New Zealand Society of Animal Production (Inc), 2018)
A mechanistic and dynamic model of a grazing ruminant, MINDY, was used to explore the effect of both the proportion dietary inclusion of plantain (PL) and its grazing management, compared with ryegrass (RG), on urinary N ...
Effect of post grazing residual and concentrate feeding on milk production in early lactation
(New Zealand Society of Animal Production, 2013)
Two strategies to increase nutrient supply to early lactation dairy cows were compared and the cumulative effects on pasture quality and milk production were investigated. In a farmlet experiment the effect of feeding ...
Can a winter-sown catch crop reduce nitrate leaching losses after winter forage grazing?
(Fertilizer and Lime Research Centre, 2016)
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined ...
Stand-off pad wintering system: Effect of surface types on cow comfort and urination behaviour
(New Zealand Society of Animal Production, 2017)
Two consecutive experiments were conducted over four weeks during winter to investigate the effect of different stand-off pad
surface types on dairy cow lying behaviour, cleanness and lameness scores, and urination frequency. ...
