Metadata[+] Show full item record
The purpose of the investigation described in this thesis was to determine the effects of early breeding in swine. If breeding immature animals results in evil consequences, these bad results should be observed in one or more of three ways: (1) influences on the pregnant mother; (2) influences on her immediate offspring; and (3) influences on the race. The particular purpose of this investigation is to determine the influence of gestation and lactation upon the growth of farm animals. To determine the effect of early pregnancy and lactation on growth, is really to determine the cause of the injurious, or the beneficial effect, if it is beneficial.
