Positive relationships between body weight of dairy heifers and their first-lactation and accumulated three-parity lactation production
(Elsevier on behalf of the American Dairy Science Association and the Federation of Animal Science Societies, 2019-03-01)
This study investigated the relationships between body weight (BW) and milk production of 140,113 New Zealand dairy heifers. Heifers were classified into 5 breed groups: Holstein-Friesian, Holstein-Friesian crossbred, ...
Milk yield and urinary-nitrogen excretion of dairy cows grazing forb pasture mixtures designed to reduce nitrogen leaching
The effect of including a mixture of forbs in a standard perennial ryegrass-white clover pasture, with or without Italian ryegrass was investigated in a two-period grazing study comparing urinary nitrogen (N) excretion and ...
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 ...
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). ...
