The concentration of lead in grass is of special interest, because animals may eat it, and high concentrations of lead are found in grass, hay or silage from pastures near highways.

Some crops, such as alfalfa and clover, are more base-requiring than are other crops, such as the grasses. Although this removal of bases in harvested crops is a very important source of acidity, the effect is usually not as great as the loss of bases through leaching. At least this is true of cultivated crops, but may not be true of pasture or hay crops where nitrification is usually inhibited, and where leaching is at a minimum. 

Tall oat grass is another very cotmnon grass of permanent pastures and hay meadows, and, as onion couch, it is also an important weed of arable land. Common couch occurs widely in permanent pastures and arable land but is less of a problem since the advent of glyphosate-based herbicides. 

Further results of introducing cattle are, first, to increase the clover content of the sward, because cattle prefer grass and, second, to increase the proportion of land required for hay or silage for the winter. Cattle often have to be fed hay/silage for six months of the year, whereas sheep require winter feeding for only two months. However, the cattle will produce much more farmyard manure, which can be put back on the pastures that were cut for hay or silage. 

The relationship between substrate and product for A-9-desaturase is reflected by the desaturase index, defined as [RA a- (RA + VA)]. Various approaches to calculating desaturase index in milk fat are discussed by Kelsey et al. (2003). In the study by Corl et al. (2001), the desaturase index was 0.23 for the hay and concentrate diet and 0.20 when the diet was supplemented with PH VO. Kay et al. (2004) reported a desaturase index of 0.25 for the pasture diet and 0.22 when the diet was supplemented with sunflower oil. Piperova et al. (2002) observed desaturase indices for highland low-fiber diets of 0.40 and 0.35, respectively. Shingfield et al. (2003) reported desaturase indices of 0.18 and 0.15 with a grass silage diet without or supplemented with fish oil these values are probably lower than others because the analytical methods accounted for minor CLA isomers that typically co-elute with RA or because of inhibition of A-9-desaturase by the long-chain PUFA from the fish oil supplement. The desaturase index, as defined earlier, should approximate the proportion of VA desaturated in the tissues. A summary of endogenous RA synthesis estimates and the proportion of VA desaturated in the tissues is in Table III. 

Grass is the best food for cows, and rich pasture results in rich milk. Your cow will get what she needs nutritionally from the grass during the summer, but in the winter, she will need supplementary feed in the form of roughage—straw or hay—and cereals for protein and carbohydrates, along with other foodstuffs such as kale or beets. 

In selechon of plants in grass mixtures on the second year of life the seed pro-duchvity was taken into considerahon as one of the main traits for culhvars of hay-field-pasture type. 

Yorkshire fog is an extremely unpalatable grass except when very young. It is especially prevalent under acid conditions where fields have been repeatedly cut for hay. Barley grass is a cotmnon weed of permanent pastures in southern England. It is also extremely unpalatable. 

The raw milk was obtained as 10 liter samples of the combined morning milk from the herd of about 80 cows at the Experimental Station of the MRI in Schaedtbek, 10 km south east of Kiel. Over the period of these investigations the cattle were kept in a roofed byre that is open to all sides. The cattle had no access to pasture and were fed on winter feed consisting mainly of hay and grass silage.
