Abstract
Production practices for first cut alfalfa (ALF), alfalfa-grass (AFG) and grass silages (GRS) were surveyed on dairy farms in four Canadian regions, i.e. British Columbia (BC, n=21), Prairies (PRA, n=32), Central Canada (CEN, n=218), and Atlantic Canada (ATL, n=17). Results are presented as percentages of responses by region; forage type, silo type, wilting method and inoculant use varied among regions. In CEN (93.0%), ATL (88.2%), and PRA (68.8%) AFG was most common. In BC, GRS was most common (66.7%). ALF was only reported in the PRA (28.1%) and CEN (5.6%). Respondents from BC only reported bunkers (52.4%) and baleage (28.6%). Bunkers were most common in PRA (31.3%), followed by baleage (28.1%), piles (18.8%) and tower silos (6.3%). In CEN tower silos were most common (37.2%), followed by bunkers (33.9%), baleage (22.0%), and piles (1.8%). In ATL bunkers (29.4%) and baleage (29.4%) were most common, followed by tower silos (17.7%), and piles (11.8%). Wilting was mostly done in windrows: BC (55.0%), PRA (45.0%), CEN (77.1%), and ATL (71.0%). In BC and ATL, 45% and 17.7%, respectively, of respondents used tedders to enhance wilting. In BC, CEN, ATL, and PRA, 55%, 58.3%, 64.7% and 44.8% respectively of respondents used inoculants.
期刊介绍:
Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
