It may, however, be difficult to make specific calculations for each and every <strong>animal</strong>. Thus, a ready reckoner or<br />
some thumb rules are easier to use in large herd.<br />

Maintenance and <strong>production</strong> need of <strong>animal</strong>s<br />
About 30 kg green fodder such as berseem, lucerne, maize, jowar or bajra will meet maintenance need of a 400<br />
kg cow or buffalo. For heavier <strong>animal</strong>s, say about 500 kg cow, 40 kg green fodder will be enough. It is desirable to mix<br />
some wheat straw (about one-tenth of green fodder) with green berseem or lucerne because these fodders are high in<br />
protein and their dry matter content is low. The requirement for milk <strong>production</strong> or that of growing calves is met by feeding<br />
green fodder as well as a balanced concentrate mixture. Some of the examples are given below :<br />
