Abstract

The objective of this study was to evaluate the intake and apparent digestibility of nutrients, as well as the feeding behavior of sheep fed an exclusively corn silage diet (0%); this diet incorporated wet corn gluten feed (WCGF) in increments of 30%, 50%, 60%, and 90%, together with the profile of the particles of these silages. Five cross-breed sheep were used with an average weight of 40 kg; they were housed in metabolic cages and were arranged in a Latin square 5×5 experimental design. There was a quadratic effect on dry matter (DM) intake, with a maximum consumption of 1.75 kg/day-1 to an inclusion of 39.09% of WCGF. The crude protein (CP) consumption exhibited an ascending linear effect with the inclusion of the co-product, and fiber consumption in neutral detergent fiber (NDF) and acid detergent fiber decreased linearly with the inclusion of WCGF. The apparent digestibility of DM, CP, and NDF increased linearly with the increasing inclusion of co-product in corn silage. Rumination time, total chewing, and idleness were influenced by increases in the inclusion of WCGF in corn silage, and there was a decreasing linear effect on the amount of time spent ruminating and total chewing, as well as an increasing linear effect for idleness duration. The chewing time for bolus, the number of chews for bolus, and the number of chews per day were influenced by the inclusion of WCGF. Through the obtained results, especially the equation of DM intake, which estimated a maximum point of 39.09%, as well as the presence of diarrhea at levels up to 50%, it was concluded that the addition of up to 40% of WCGF in corn silage can be recommended as it improves nutrient intake and features good digestibility without negatively altering the normal behavior of sheep.
