This study evaluated animal performance, carcass characteristics and meat quality of 36-month old Nellore steers finished in pastures (n = 10) and 20-month old Angus vs. Nellore bulls finished in feedlot (n = 10). Final body weight, carcass weight, characteristics, conformation and fat thickness, were higher (p &lt; 0.001) for the Nellore steers than for Angus vs. Nellore bulls. Water losses during chilling (24 hours, 4oC) were lower (p &lt; 0.05) for Nellore steers than for the Angus vs. Nellore bulls. Muscle percentage on the 6th rib was higher (p &lt; 0.05) for the Nellore steers than for Angus vs. Nellore bulls; while bone percentage was lower (p &lt; 0.05) for Nellore steers. After 7 and 14 days of ageing, the L* meat value was higher for the Nellore...

Intensive dairy farming systems from Holland and Brazil: SWOT analyse comparison
Provedor de dados: 2
Autores: Passetti, Rodrigo Augusto Cortêz; Eiras, Carlos Emanuel; Gomes, Ludmila Couto; Santos, Junio Fabiano dos; Prado, Ivanor Nunes do.
Intensive systems of milk production in Brazil and Holland are compared by SWOT analysis. Twenty-one farms, 10 in Wageningen, central region of Holland, and 11 in Castro, central-eastern region of the state of Paraná, Brazil, were sampled. Data were retrieved from semi-structured interviews with the owners or people responsible for dairy activities, using a questionnaire guide and a digital recorder. After results were analysed, a table was elaborated representing the strengths, weaknesses, opportunities and risks for each country. Dairy farms in Holland were uniform, or rather, small and medium-sized farms with high production. It has also been observed that Dutch farms have several problems due to high intensification, for example, hoof diseases with...

Concentrate levels of crossbred bulls slaughtered at 16 or 22 months: performance and carcass characteristics
Provedor de dados: 2
Autores: Pinto, Adriana; Passetti, Rodrigo Augusto Cortêz; Guerrero, Ana; Rivaroli, Dayane Cristina; Perotto, Daniel; Prado, Ivanor Nunes do.
This study was performed to assess the animal performance of 97 bulls, ½ Purunã vs. ½ Canchim, that were slaughtered at 16 (16M) or 22 (22M) months with three concentrate levels (0.8, 1.2, and 1.6%) of body weight (BW). The initial body weight was lower for the 16M bulls. The final body weight and hot carcass weights were similar between the two slaughter ages. The hot carcass dressing was higher for 22M bulls. The average daily gain was higher for 16M bulls. The feed intake and dry matter feed conversion were similar between 16 and 22M bulls. The carcass length, marbling, and bone percentage were lower for 16M bulls. However, the Longissimus dorsi muscle area was higher for 16M bulls. The leg length, cushion thickness, fat thickness, conformation, colour,...
