[Suitability of various food mixtures for breeding and rearing of beagle dogs. 3. Methods and results for the Ingelheim team].

Two different modes of nutrition during breeding and rearing of dogs are investigated to determine which of them has the better effect. The use of a complete feed for breeding and maintenance (Altromin H) was compared with the use of a special breeding feed (Zahn Z), respectively, together with a special maintenance feed (Zahn H). A palatability test was made, a 2-year test for the effect on breeding, observation of weight gain and food consumption in the rearing phase on all the dogs of the strain Chbi:BEAGLE.

The effect of illegitimacy on U.S. general fertility rates and population growth.

Abstract Illegitimacy and bridal pregnancy has attracted the attention of scholars concerned with a variety of plausible causes and consequences ofbirths conceived out of wedlock. Sociologists have expressed concern with the impact of such births on maternal and child health, family stability and the economic status offamilies. Although demographers have described trends in various populations, and have occasionally suggested that births conceived out of wedlock influence general fertility rates and cohort fertility, measures of the demographic impact of illegitimate or premaritally conceived births have not been assessed.
