HEREDITARY

DEVELOPMENT OF POSSIBILITIES. ANIMALS MUST BE FED. An animal must have feed to develop its hereditary possioiiities. ior example, a steer may have the necessary heredity to maKe 10001 b at one year olu if properly fed, but if he is only fed sufficiently to make 8001 b ho cannot make 10001 b. On the other hand, if a steer has the heredity necessary to make him an 8001 b steer at one year, he may consume each feed tn make a 10001 b steer, but he will only go to the limit of his heredity. In such a case the difference is largely an hereditary difference. The steer that has only enough heredity to make 8001 b in a year does not utilise his feed to the same degree of efficiency as the 10001 b steer. Therefore, he is less desirable, because he is more wasteful. Moreover, a dairy cow may have an hereditary make-up to yield 10001 b of butterfat in one year, but in order to do this she must be well fed. On the other hand, she may be limited in heredity by only having sufficient heredity to yield 5001 b of butter-fat in a year when well fed. This cow cannot be forced to produce 10001 b of butter-fat. _ The difference between these cows is largely an hereditary difference. The same principle can be applied to poultry, sheep and hogs.
