Production 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 کاملEffect 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 کاملPodolian beef production on pasture and in confinement.
From February to August 2007 the effect of rearing system (confined (C) v. free ranging (FR)) and season (spring v. summer) was evaluated on behaviour, immune and blood parameters and beef production (experiment 1). From February to August 2008, the effect of rearing system was only evaluated on beef production (experiment 2). A total of 12 Podolian young bulls were used each year. They were sl...
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 کاملMilk Production from a Tropical Legume-grass Pasture
One member of each of three pairs of monozygous twin dairy cows was fed freshly cut Glycine javanica and kikuyu-grass pasture ad libitum while the co-twins were fed lucerne hay ad libitum and a concentrate mixture. The mean daily digestible organic matter and digestible crude protein intakes for the cows fed pasture were 7.0 kg and 1.35 kg, and for the cows fed hay and concentrates were 10.2 kg...
