“…The TCT values were similar to those reported by Azevedo et al (2013), who evaluated different levels of macauba meal in lambs, and Carvalho et al (2004) when studying the inclusion of 15 and 30% cocoa meal and palm kernel, respectively, in the concentrate feed. In the present study, the 30:70 diet presented a higher feeding efficiency than the 70:30 diet, which may have been influenced by the feed particle size (Table 3).…”

“…In the present study, the 30:70 diet presented a higher feeding efficiency than the 70:30 diet, which may have been influenced by the feed particle size (Table 3). The results obtained were lower than those found by Azevedo et al (2013) and Figueiredo et al (2013) who assessed different fiber sources, and Mousquer et al (2013) who assessed sheep fed with silage. The feeding efficiency values were similar to those found in the previous studies.…”

“…For example, the main daily activities of sheep are feeding, rumination, and resting (FIGUEIREDO et al, 2013). Moreover, the most studied parameters are feeding, rumination and rest time, number of meals, periods of rumination, feeding efficiency (MACEDO et al, 2007), number of ruminating chews per bolus, time spent with chews per ruminal bolus, and number of ruminating chews per day (BÜRGER et al, 2000).…”

It was evaluated the feeding behavior of lambs fed diets containing 30% sorghum silage and 70% crambe cake (30:70 diet), and 70% sorghum silage and 30% crambe cake (70:30 diet) under voluntary and controlled consumption. The experimental design used was a 4 × 4 Latin square, with four animals, four periods, and four treatments; feeding behavior was determined by observation. The results indicated that animals fed the 30:70 diet showed higher DM and NDF (g day -1 ) than those fed the 70:30 diet. Animals fed the 70:30 diet showed longer feeding times (h kg -1 DM), mastication (min kg -1 DM and min kg -1 NDF), rumination (min day -1 and min kg -1 DM), and the largest number of mericics chewing per bolus; however, a higher feed efficiency (g DM h -1 ) was observed in the 30:70 diet group. Furthermore, animals feeding voluntarily had higher DM intake and chewed for longer. Therefore, the combined results indicated that crambe cake could be used in the diet of sheep without affecting feeding behavior.

-This study evaluated the effects of crude glycerin (CG) supplied separately from the other dietary ingredients to goats during the feedlot and in the pre-slaughter lairage on the nutrient intake, performance, behavioral and physiological parameters, carcass characteristics, and meat quality. Twenty-eight uncastrated male goats from a cross between the Boer breed and mixed-breed goats were used in a completely randomized design in a 2 × 2 factorial scheme, consisting of the feedlot with or without CG inclusion in the diets (96.90 g kg -1 DM) and the pre-slaughter lairage, also with or without the ingredient. In the feedlot, goats fed CG had a lower intake of dry matter and nutrients. Crude glycerin intake reduced the weight gain and body weight of goats and increased feed conversion. Weights of carcass and cuts (leg, loin, ribs, and shoulder) were lower when the animals consumed CG in the feedlot. In pre-slaughter lairage, concentrations of cortisol were lower when the animals consumed CG. Characteristics of carcass and meat (pH, color, water holding capacity, cooking loss, and shear force) were not changed by the supply of CG during the pre-slaughter. When supplied during the feedlot period and separately from the other dietary ingredients, CG negatively affected the performance and carcass characteristics of goats without changing meat quality. In the pre-slaughter lairage, CG intake lowers the cortisol level and does not change the behavioral parameters or carcass and meat characteristics of goats.

“…Artificial lighting was used during nighttime observations. The feed and rumination efficiencies, expressed as g DM/hour were obtained by dividing the average daily intake of DM by the total time spent eating and/or ruminating in 24 hours, respectively (AZEVEDO et al, 2013). The total time in minutes per day for each animal spent in each activity was calculated by multiplying the total number of observations by five.…”

SUMMARY The objectives of this research were to determine the effects increasing levels of concentrate on nutrients digestibility, performance, economic viability of diets and ingestive behavior of lambs. Fifteen crossbred lambs were used in a randomized complete block design according to initial body weight and age. Lambs were penned individually during 55 days, being 10 days for adaptation of diets and 45 days for data collection. The treatments consisted in three isonitrogenous diets with increasing levels of concentrate: 40, 60, or 80%, in dry matter basis. No effect (P>0.05) were observed on dry matter intake, crude protein intake, crude protein digestibility and neutral detergent fiber digestibility, whereas the dry matter digestibility was lower (P<0.01) for lambs fed diets with 40% of concentrate. The addition of 80% concentrate decreased (P<0.05) neutral detergent fiber intake, however this treatment provided higher average daily gain, followed by 60 and 40% of concentrate. In relation to feeding behavior, the animals fed80% concentrate spent more time with feeding (P<0.05) compared to the other treatments. It is concluded that supplementation of concentrate between 60 to 80% improves dry matter digestibility and performance of crossbred lambs without relevant affect dry matter intake and ingestive behavior. A diet with 80% concentrate provides positive gross margin of profit.
