Assessing the nutritional value of agroindustrial co-products and feed through chemical composition, in vitro digestibility, and gas production technique Animal Sciences
Olivo, Paula Martins; Santos, Geraldo Tadeu dos; Ítavo, Luís Carlos Vinhas; Silva Junior, Ranulfo Combuca da; Leal, Eduardo Souza; Prado, Rodolpho Martin do.
Agroindustrial co-products are a viable alternative for use in animal nutrition. Tests were conducted using eight different types of co-products and feed to evaluate the chemical composition, in vitro digestibility of dry matter, crude protein and neutral detergent fiber, and gas production by them. The co-products tested were: coffee hulls; pelleted citrus pulp; grape residue; soybean hulls; cottonseed; cassava foliage; and foods usually supplied to ruminants: corn silage and ground corn concentrate. Data of in vitro digestibility of dry matter, crude protein and neutral detergent fiber were tested by analysis of variance using the least square method; the results of gas production were interpreted by a non-linear regression by the Gauss-Newton method;...

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 Animal Sciences
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...

Propolis and essential oils additives in the diets improved animal performance and feed efficiency of bulls finished in feedlot Animal Sciences
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...
