Evaluation of Nelore, Canchim, Santa Gertrudis, Holstein, Brown Swiss and Caracu as Sire Breeds in Matings with Nelore Cows. Effects on Progeny Growth, Carcass Traits and Crossbred Productivity

Over three calf crops, 1096 exposures of 380 Nelore (a Zebu breed) cows to 6 sire breeds Nelore (N), Canchim (C), Santa Gertrudis (G), Holstein (H), Brown Swiss (S), and Caracu (K), resulted in 644 calves weaned for a 63% calving rate. Sire breed effect was significant for birth weight, weaning weight, 13 mo weight and 18 mo weight. HN and SN calves were the heaviest at all weight periods wile CN, GN, and KN calves were the intermediates. Average daily gain from 18 mo to slaughter age was measured in 125 males finished in feed lot and 116 on pasture. A significant breed of sire × finishing system interaction was observed. Under feed lot, HN and SN had higher daily gain and dry matter intake per kg of metabolic weight than the other ones. HN calves showed the worst feed conversion. The average slaughter age was 788 d for feed lot and 989 d for pasture finished steers. Carcass traits were evaluated in 241 slaughtered animals. CN calves had the highest dressing % and edible portion % under both finishing conditions. Crossbred group productivity (calculated as 18 mo weight times the weaning rate %) was greater for locally adapted breeds of sire

Dilatação dos confins: caminhos, vilas e cidades na formação da Capitania de São Paulo (1532-1822)

Este ensaio analisa a formação da rede urbana das capitanias de São Vicente e Santo Amaro, depois unidas na Capitania de São Paulo. Discute o processo de apropriação do sertão, a pulsação e dilatação dos confins ao sabor dos deslocamentos humanos e de interesses políticos. Interpreta o papel de capelas, freguesias, vilas e cidades no controle e produção de territórios metropolitanos em solos ultramarinos.This essay analyzes the development of urban networks in the Captaincies of São Vicente and Santo Amaro, later merged into the Captaincy of São Paulo. It discusses the process of appropriation of the sertão (backcountry), the commotion and expansion beyond the confines to the tune of population movements and political interests. The paper also interprets the role of chapels, parishes, villages and towns in initiatives to create and control metropolitan areas on overseas soil
