Ambrosia artemisiifolia is a highly invasive weed. Identifying the characteristics and factors influencing its establishment population growth may help to identify high invasion risk areas facilitate monitoring prevention efforts. Six typical habitats: river banks, forests, road margins, farmlands, grasslands, wastelands, were selected from main distribution of A. in Yili Valley, China. propagu...

The paper describes and discusses the experience in mapping pasture types on the Tibetan Plateau. After pasture data recording in the fi eld campaign of 2004 the application of remote sensing and GIS to refi ne the vegetation mapping became viable. The vegetation types that resulted from the analysis of the fi eld data were aggregated into four main categories ( ́Kobresia pasture`, ́Miscellaneou...

Pasture-based automatic milking systems (AMS) require cow traffic to enable cows to be milked. The interval between milkings can be manipulated by strategically allocating pasture. The current experiment investigated the effect of replacing an allocation of grazed pasture with grazed soybean (Glycine max) with the hypothesis that incorporating soybean would increase voluntary cow traffic and mi...

This study was conducted to investigate the infl uence of pasture intake on meat quality, lipid oxidation, and fatty acid composition of geese. One hundred twenty Dongbei White male geese (a local breed; BW = 878 ± 13 g; 28 d old) were randomly and equally divided into 2 treatments with 6 pens of 10 geese per treatment. The 2 treatments consisted of birds fed ad libitum a corn-based feed. One-h...

The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties when 50% of the total diets were provided from home grown feed either as pasture or grazeable complementary forage rotation (CFR) in an automatic milking system (AMS). Twelve scenarios consisting o...

A number of factors influence dairy cow preference to be indoors or at pasture. The study reported here investigated whether herbage mass and distance affects preference and if continuously housed cows exhibited behavioral and production differences compared to cows that had free access to pasture. Dairy cows (n = 16) were offered a free choice of being in cubicle housing (1.5 cubicles/cow) or ...
