Resumen
Aimed to evaluate the effect of inclusion of the residue from the
processing of beans to replace cottonseed meal in diets for feedlot sheep. The
experiment was conducted at the Federal University of Mato Grosso -campus
Rondonópolis-MT. 16 sheep mongrel males with a mean age of 12 years and a
mean weight of 30 kg, distributed in a completely randomized design with four
treatments and four replicates were used in the experimental test. The diets
were formulated to contain 45% forage and 55% concentrate on dry matter. The
treatments consisted of the replacement of cottonseed meal per bean residue at
levels of 0, 33, 66 and 100% in the concentrate. Diets were formulated to be
isonitrogenous crude protein content of 14%. The experiment lasted twenty
days and fifteen days for adaptation to the diets and environment and remaining
five days to monitor the consumption and collections. We evaluated the
consumption and digestibility of DM, OM and dietary nutrients, the kinetics of in
vitro ruminal fermentation of food (elephant grass silage, soybean, bean
residue, cottonseed meal, corn), the grazing behavior receiving the
experimental diets. We also evaluated the use of internal indicators (MSi, NDFi,
ADFi) and external (Cr2O3). Data were subjected to regression analysis, the
choice of parameters based on the significance of the regression models and
coefficients of determination. Inclusion levels of common bean residue to
replace cottonseed meal altered the intake of DM, OM, CP, NDF and TDN
significant quadratic response (P<0.05) intakes of 1221.94; 1142.97; 178,35;
471.17 and 888.29 g / day, respectively. EE intake in g / day, showed a linear
decrease (P<0.05) increased as the levels of residue substitution of beans,
whi le the CNF intake in g / day, increased linearly (P<0.05). The apparent
digestibility of DM, OM, CP and CNF increased linearly (P<0.05) the digestibility
of EE had no significant effect (P>0.05), while the digestibility of NDF showed
quadratic effect (P<0.05) increased as the inclusion levels of common bean
residue replacing the cotton cake, with 65.03% digestibility. The cumulative gas
production ranged from 47.47 to 150.61 mL for cottonseed meal and corn meal.
For the fraction of rapidly digested carbohydrates (CNF) were estimated ruminal
volumes of gases ranging from 20.79 to 77.69 mL, respectively for cotton cake
and bean residue. Digestion rates for the fraction of fast-digesting (CNF)
ranging from 0.0307 to 0.1879 h-1 for napier grass silage and ground corn,
respectively were estimated. For the fraction of slow digestion (B2), gas
productions ranging from 26.25 to 81.10 mL, for cottonseed meal and ground
corn, respectively were estimated. For the fraction of slow digestion (B2)
digestion rates varying from 0.0182 to 0.0321 h-1 for the residue of crushed
beans and corn were estimated. As the variables of ingestive behavior, the total
time of supply (hours / day), leisure time (hours / day), efficiency of DM and
NDF intake and rumination efficiency of MS showed a quadratic response
(P<0.05), with 5.71 hours; 9.21 hours; MS 237.98 g / hour; 85.04 g NDF / hour
and 145.54 g DM / hour. The total rumination time (hours / day) had no
significant effect (P>0.05) as increased levels of substitution of cottonseed meal
per residue beans with an average of 8.43 hours. The number of ruminated
daily chewing time and number merícica diary ruminating chewing showed a
quadratic effect (P<0.05) with 793.71 cakes / day; 14.73 hours; 50796.44 chews
/ day. Chewing time per bolus, the number of periods of eating, ruminating and
idling showed no significant effect (P>0.05) with a mean of 41.12 second / cake;
33.56; 50.62 and 59.96 times / day. Regarding the use of indicators, there was
no significant interaction (P>0.05) between diets and the use of indicators. The
estimated fecal excretion (g / day) of the experimental diets used, regardless of
the indicator showed no statistical difference (P>0.05) with an average of 371 g
/ day. The apparent digestibility quadractricaly signi ficant effect (P<0.05)
between diets with maximum digestibility of 71.02%, regardless of the indicator
used. To estimate fecal output (g / day) and apparent DM digestbilidade no
statistical difference (P>0.05) when using internal indicators (MSi, NDFi, ADFi)
and external (Cr2O3) averaging 371 g / day and 67.20%, respectively,
regardless of the diet. The residue of beans can replace cottonseed meal by up
to 60% in the concentrate. Indicators, internal and external, are efficient in
estimating the faecal excretion and apparent digestibility.
