Ingestive Behavior of Ovine Fed with Marandu Grass Silage Added with Naturally Dehydrated Brewery Residue.

The objective was to evaluate the ingestive behavior of ovine fed Marandu grass silage with dehydrated brewery residue added. The experiment had a completely randomized design with five treatments and four repetitions, with the treatments levels of inclusion being of 0, 10, 20, 30, and 40% natural matter of naturally dehydrated brewery residue for 36 hours to the marandu grass silage. 20 ovines were used and the experimental period was 21 days, 15 being for adaptation to diets. The use of brewery byproduct promoted quadratic effect (P < 0.05) for the consumption of dry matter with maximum point value estimated at adding 23.25% additive. Ingestion efficiency and rumination efficiency of dry matter (g DM/hour) were significant (P < 0.05), by quadratic behavior, and NDF ingestion and rumination efficiency showed crescent linear behavior. The DM and NDF consumption expressed in kg/meal and in minutes/kg were also significant (P < 0.05), showing quadratic behavior. Rumination activity expressed in g DM and NDF/piece was influenced (P < 0.05) by the adding of brewery residue in marandu grass silage in quadratic way, with maximum value estimated of 1.57 g DM/bolus chewed in inclusion of 24.72% additive in grass silage. The conclusion is that intermediary levels adding of 20 to 25% dehydrated brewery residue affects certain parameters of ingestive behavior.

Comportamento ingestivo de ovinos em pastos de diferentes estruturas

Sheep are gregarious animals and spend time with food intake inserted with one or more periods of rumination or leisure. The peaks of grazing and ruminating usually happen in the cooler hours of the day, keeping in idle at times of higher temperatures. These animals modify one or more components of their ingestive behavior seeking to overcome limiting conditions for their consumption and get the necessary amounts of nutrients for the maintenance and production. Thus, this review has as an objective to discuss these items that affect the sheep’s intake behavior at pasture. The feeding behavior study cooperates in solving problems related to the decrease in consumption in critical times for milk or meat, through of management practices, installation design and supply diet with quantity and quality.

Glicerina bruta de biodiesel na alimentação de ruminantes

Biodiesel is considered an environmentally friendly fuel, biodegradable, nontoxic, and virtually free of sulfur and aromatics, when replacing the conventional diesel, biodiesel can reduce emissions of hydrocarbons and carbon monoxide with the search for renewable sources. For each ton of biodiesel are produced about 100 kg of glycerol, with the accumulation of this coproduct in the environment can cause contamination of soil and water, thus, research is being undertaken to find alternatives to the use of surplus glycerol. The cost of animal feed is around 70% of all production. And one of the ways to be decreasing this cost power is the use of by-products like glycerin in animal feed and also helping to preserve natural resources (no pollution).Biodiesel is considered an environmentally friendly fuel, biodegradable, nontoxic, and virtually free of sulfur and aromatics, when replacing the conventional diesel, biodiesel can reduce emissions of hydrocarbons and carbon monoxide with the search for renewable sources.
