Effect of winter pasture residuals’ and grazing- off on subsequefit milk production and pasture performance
Concern at the effect of winter pasture residuals on pasture productivity led to the comparison of different wintering systems at the DRC No. 3 Dairy from May-December 1993. Three farmlets were designed to have 2000 kg DM/ha average farm cover at calving, but with pastures grazed to either 900, 1400 or 1800 kg DM/ha at least once during the winter. A fourth farmlet was spelled from grazing from...
متن کاملNutritional limitations to increased production on pasture-based systems.
The constraints to high levels of milk production imposed by a high-quality-pasture diet, and development of feeding strategies to overcome these limitations, were examined by modelling the nutritional status of New Zealand Friesian and North American Holstein-Friesian dairy cows grazing high-quality pasture. The Cornell Net Carbohydrate and Protein System (CNCPS) was used to predict sensitivit...
متن کاملThe effect of frequency of pasture allocation on the milk production, pasture intake and behaviour of grazing cows in a subtropical environment
Two studies were conducted in a subtropical environment to examine the effects on milk production and nutrient intake of Holstein-Friesian cows of offering a daily pasture allowance as various numbers of allocations within a day. In Study 1, 24 multiparous cows [half early lactation (mean ± s.e. of 57 ± 16.2 d postpartum), half mid–late lactation (204 ± 32.9 d post-partum)] were allocated to 2 ...
متن کاملProduction pasture versus exercise and recreation pasture for cows in automatic milking systems
In an automatic milking unit, a daytime grazing system with production pasture (group P) was compared with offering cows a small grass-covered paddock only for exercise and recreation, i.e. exercise pasture (group E). Two experiments (Exp1 and Exp2) were performed during 12 and 5 weeks with 53 cows and 42 cows, respectively. Group P was offered new pasture daily with night-time access to grass ...
متن کاملInteractions between beef cattle and simulated tuberculous possums on pasture.
Brushtail possums (Trichosurus vulpecula) were sedated with ketamine and placed within a fenced observation area with 17 Hereford cross steers. The behaviour of the sedated possums simulated that of terminally ill possums. Behavioural analysis was carried out during eight observation periods in which sedated possums were successfully released and interactions occurred. Cattle were attracted fro...
