Relationships among heifer traits, early-life productive traits, and lifetime productivity within Angus and Simmental female cattle
… of both breeds, fertility was associated with birth date, weaning weight ratio and weaning-yearling relative growth rate (RGR). The only calfhood trait that consistently affected fertility in the second breeding season was birth weight of the cow. Fertility of first parity Simmentals was also …

Ontogenesis of Peptide Transport and Morphological Changes in the Ovine Gastrointestinal Tract
… of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on the potential for peptide transport via PepT1 …
