Effect of the inclusion of wet gluten feed on the in situ production of ruminal gases
Agro-industry generates a wide variety of feed of high nutritional value for livestock, which are increasingly used according to several benefits, like lack of food competition with the human consumer, lower costs and reduced environmental impact of waste. Gluten feed is one these by-product derived from the wet milling of corn with nutritional properties that meet some of the basic bovine nutritional requirements, although its organoleptic characteristics may limit animal consumption. The objective of this work was to provide a better understanding the possible effects of different GF proportions in diets on ruminal microorganisms, evaluated through in situ measurements of fermentation gases, and how this last may be buffered through chemical parameters of the diet. The comparisons between the interaction of GF inclusion and the concentration of enteric gases were highly significant (p <0.0001). Methane production covered a range from 14.9 to 23.7% of the volume (% Vol.), showing a quadratic behavior. The best regression fit was obtained with digestibility (R2 = 0.58), while the concentration of NH3 showed a low coefficient of determination with digestibility (R2 = 0.11) and high with CP (R2 = 0.70). The results with 85% inclusion of GF showed a daily gain of 12.93 gr/KgPV0.75, not showing negative effects caused by its high levels of sulfates. The use of this by-product may be part of a low carbon livestock strategy, by reducing the economic costs of the diet, increasing the production capacity and reducing the risks of environmental contamination.
Keywords: low carbon livestock, ruminal gases, by-products.
