Animal welfare encompasses all aspects of an animal's life and the interactions between animals. Consequently, welfare must be measured across a variety of factors that consider aspects such as health, behaviour, and mental state. Decisions...
Combining ability and performance of extra-early maturing yellow maize inbreds in hybrid combinations under drought and rain-fed conditions [0.03%]

M Leggett et al.
Findings from multi-year, multi-site field trial experiments measuring maize yield response to inoculation with the phosphorus-solubilizing fungus, Penicillium bilaiae Chalabuda are presented. The main objective was to evaluate representati...
The effects of treading by two breeds of dairy cow with different live weights on soil physical properties, poaching damage and herbage production on a poorly drained clay-loam soil [0.03%]
两种体重不同的奶牛踩踏对排水不良的壤土物理性质、泥泞损伤和牧草产量的影响
P Tuohy,O Fenton,N M Holden et al.
P Tuohy et al.
There is little empirical evidence to indicate that dairy cow live weight affects the extent of soil damage at the hoof-soil interface during grazing on poorly drained permanent grassland. In the present study the impact of Holstein-Friesia...
Emissions of nitrous oxide and ammonia from a sandy soil following surface application and incorporation of cauliflower leaf residues [0.03%]
甘蓝叶片残体表施和混土后沙质土壤氧化亚氮和氨气排放响应研究
L Nett,R Fuß,H Flessa et al.
L Nett et al.
Vegetable production systems are often characterized by excessive nitrogen (N) fertilization and the incorporation of large amounts of post-harvest crop residues. This makes them particularly prone to ammonia (NH3) and nitrous oxide (N2O) e...
Effect of breed and pasture type on methane emissions from weaned lambs offered fresh forage [0.03%]
品种和牧草类型对断奶羔羊甲烷排放的影响
M D Fraser,H R Fleming,V J Theobald et al.
M D Fraser et al.
To investigate the extent to which enteric methane (CH4) emissions from growing lambs are explained by simple body weight and diet characteristics, a 2 × 2 Latin square changeover design experiment was carried out using two sheep breeds an...
Is it necessary to split nitrogen fertilization for winter wheat? On-farm research on Luvisols in South-West Germany [0.03%]
冬小麦有必要分次施用氮肥吗？西南德国 Luvisol 农场试验研究
R Schulz,T Makary,S Hubert et al.
R Schulz et al.
Mineral nitrogen (N) fertilization in cereals is commonly split into three or four applications. In order to simplify N fertilization, a single N application either broadcast or placed on the soil surface was compared to conventionally spli...
