Provedor de dados: 2
Autores: Barcellos, Vinicius Cunha; Mottin, Camila; Passetti, Rodrigo Augusto Cortêz; Guerrero, Ana; Eiras, Carlos Emanuel; Prohmann, Paulo Emilio Fernandes; Vital, Ana Carolina Pelaes; Prado, Ivanor Nunes do.
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...

Crambe meal in supplements for culling cows: animal performance and carcass characteristics
Provedor de dados: 2
Autores: Souza, Kennyson Alves de; Goes, Rafael Henrique de T. B.; Silva, Luiz Henrique Xavier da; Yoshihara, Mayara Mitiko; Prado, Ivanor Nunes do.
The influence of the replacement of soybean meal by crambe crushed in concentrated supplement at proportions 0, 5, 10, 15%, on the performance and carcass traits of grazing cows is assessed. Within a completely randomized design, twenty Nellore cows, fed on Brachiaria humidicola, were supplemented during the rain-drought transition period and monitored with regard to weight and body conditions every 28 days. Total forage mass and percentages of leaf, stem and senescent material were quantified in loco. The estimation of forage quality consumed by animals was performed by the simulated grazing method. There were no significant differences between the levels of inclusion of crambe crushed on animal performance or carcass characteristics. Replacement did not...

How the perception of quality for beef evaluated by the buyer at the time of purchase: Study in three Brazilian cities of different sizes – Curitiba, Campo Mourão and Palotina
Provedor de dados: 2
Autores: Barcellos, Vinicius Cunha; Mottin, Camila; Prado, Rodolpho Martin do; Schenkel, Tiago; Viana, Cibeli; Vital, Ana Carolina Pelaes; Bersot, Luciano dos Santos; Sañudo, Carlos; Prado, Ivanor Nunes do.
In order to evaluate how beef buyers in the State of Paraná, Brazil south value meat quality indicators, and attributes of credibility, 519 interviews were conducted in three cities with different sizes (Big – Curitiba, Medium – Campo Mourão and Small – Palotina). The interviews were applied after the meat was placed in the shopping cart and were composed of five questions, including question of spontaneous response: (i) factors that the buyer considers at the purchasing time; (ii) information which the buyer considers important to appear on the meat label; and three questions of stimulated response: (i) preference for meat preparation and exposure for sale, (ii) factors that the buyer considers when purchasing the meat, and (iii) preference for marbling...

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,...

Influencing factors of consumer willingness to buy cattle meat: An analysis of survey data from three Brazilian cities
Provedor de dados: 2
Autores: Mottin, Camila; Eiras, Carlos Emanuel; Chefer, Daniele Maggioni; Barcellos, Vinicius da Cunha; Ramos, Tatiane Rogélio; Prado, Ivanor Nunes do.
Brazil is currently undergoing a process to establish new patterns of consumption habits and the implementation of a new concepts of meat quality. The process emphasizes the quality of information delivered to consumers, which is part of the new approach to meat quality and food safety. The objective of this article is to investigate the attributes considered important when buying beef, knowledge about the production process, labelling, cuts and characteristics of the animals. The study included 276 consumers in three Brazilian cities and their responses were examined in relation to the semi-structured form with fifteen spontaneous and stimulated questions. It was verified that the presentation of the product is regarded as the most important attribute at...

Propolis and essential oils additives in the diets improved animal performance and feed efficiency of bulls finished in feedlot
Provedor de dados: 2
Autores: Valero, Maribel Velandia; Prado, Rodolpho Martin do; Zawadzki, Fernando; Eiras, Carlos Emanuel; Madrona, Grasiele Scaramal; Prado, Ivanor Nunes do.
This work was realized to evaluate the effect of natural additives as propolis or essential oils addition on animal performance, feed intake, apparent digestibility and carcass characteristics of bulls finished in feedlot. Thirty bulls (½ Aberdeen Angus vs. ½ Nellore) were randomly assigned in one of three diets (control – CON, propolis – PRO and essential oils – OIL) and kept in feedlot (individual pen) during 55 days. CON diet consists of 45% corn silage, 40% concentrate (cracked corn, soybean meal, limestone and mineral salt) and 15% glycerine. The PRO group received same diet that control plus 3 grams to animal day-1 of propolis dry added to the concentrate. The OIL oils group received same diet that control and 3 grams to animal day-1 of essential...

How does the dietary cottonseed hull affect the carcass characteristics and meat quality of young bulls finished in a high-concentrate diet?
Provedor de dados: 2
Autores: Eiras, Carlos Emanuel; Ornaghi, Mariana Garcia; Valero, Maribel Velandia; Rivaroli, Dayane Cristina; Guerrero, Ana; Prado, Ivanor Nunes do.
This study evaluated the effects of diets composed by cottonseed hull and meat aging on carcass characteristics and meat quality from young bulls fed on a high-concentrate system. Thirty crossbred bulls were assigned in a complete randomized experimental factorial design with three diets (CH21: cottonseed hull 210 g kg-1on a DM basis, CH27: cottonseed hull 270 g kg-1on a DM basis and CH33: cottonseed hull 330 g kg-1on a DM basis) and different aging times (24 hours and 3, 7 and 14 days). Meat from CH27 diets presented smaller LM moisture content (p &lt; 0.05). Total lipids were smaller in CH33 diet (p &lt;0.05). At 24 hours, CH21 diet presented smaller LM cooking loss than other diets. The increasing aging time reduced the shear force (p &lt; 0.001) on the...
