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...

Winter-annual pasture as a supplement for beef cows.

In each of two experiments, 120 pregnant beef cows were stratified by body condition score, BW, breed, and age, randomly divided into six groups of 20, and assigned to one of six 5.1-ha bermudagrass (Cynodon dactylon [L.] Pers.) pastures (two replicates/ treatment) in early January to evaluate the use of winter-annual pasture as a supplement. All cows in Exp. 1 and 2 had ad libitum access to be...

Soil Nitrocxn and Pasture Management

The. seasonal pattern of nitrogen mineralization is described and compared with the potential demand for nitrogen by grasses. Peak mineralization rates occur in spring but are quite inadequate for expression of potential grass growth. Nitrogen fixation by clovers provides a significant input into the system over a short period. Consideration of the fate of fixed nitrogen shows that losses large...

The Management and Utili- Zation of Pasture by Pigs

The New Zealand farmer who breeds pigs tends to place either too much emphasis upon the value of pasture, with rather dire effects, or too little, with the result that he deprives himself of a valuable addition to his basic feed supply. In this paper an attempt will be made to assess the value of pasture in the New Zealand pig keeping economy over the whole production cycle from the mating of t...
