Efeito da Selecao para Peso Pos-desmama sobre Indicadores da Eficiencia Produtiva de Vacas da Raca Nelore


, : Efeito da Selecao para Peso Pos-desmama sobre Indicadores da Eficiencia Produtiva de Vacas da Raca Nelore. Revista Brasileira de Zootecnia 29(4): 1020-1027

The objective of this study was to evaluate the productivity efficiency indicators of cows selected for post-weaning weight, with emphasis in the calf-cow weight ratios, in a controlled herd (NeC), unselected for post-weaning weight, selection (NeS) and conventional (NeT). The analysis involved 3929 and 3906 calves weights at the 120 (P120) and 210 (P210) days of age, respectively.

Doping quantum dots (QDs) with lanthanide (Ln) ions is promising to modify the optical properties of QDs, but incorporating Ln(3+) ions into QD hosts remains a challenge. In this work, we adopt the trapped-dopant model for fabricating Eu-doped ZnS...
