The experiment was conducted at the Universidade Federal Rural de Pernambuco (UFRPE). Four male sheep and four male goats were studied, castrated and fistulated in the rumen, with average initial body weight of 71.9 kg and 64.85 kg, respectively, distributed in two contemporary 4x4 Latin squares. The experiment had a duration of 76 days, with four periods of 19 days each, being 12 days for adaptation to the experimental conditions and 7 days for data collection and sampling. The experimental diets were composed by Tifton 85 hay as forage; grounded corn, soybean bran, residues from the industries of candy, gum, powdered juice and derivatives in combination with corn gluten (Protenose ®) and mineral blend, as concentrated. The treatments consisted of inclusion of residues from the candy industry at levels of 0, 33, 66 and 100%. The variables were evaluated by analysis of variance and regression, using PROC MIXED and PROC REG of the SAS. Consumption of dry matter (DM), mineral matter (MM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TCHO) and total digestible nutrients (TDN) were not influenced (P> 0.05) by the inclusion levels of residues from the candy factory in the diet, presenting averages of 874.89, 59.280, 815.61, 113.49, 345.20, 685.21 and 660.51g/day, respectively. In contrast, there was a significant effect on ethereal extract (EE) and non-fibrous carbohydrates (CNF) intake. The intake of EE was influenced (P <0.05) by dietary treatments, decreasing linearly as the sweet residue content increased. There was a quadratic effect on CNF intake as corn substitution was performed. Increasing levels of candy residues in the diets of small ruminants did not have an effect on the apparent digestibility of DM, OM, NDF and TCHO, with average values of 782.8, 792.2, 650.9 and 795.3g/kg, respectively. However, they favored an increasing linear effect on the apparent digestibility of CP and CNF and a linear decreasing effect on the apparent EE digestibility. Residues from the candy industry in association with Protenose® may replace up to 100% based on the dry matter of the diet of small ruminants, without adversely affecting the intake and apparent digestibility of the nutrients.Item Digestibilidade dos nutrientes em ovinos Santa Inês recebendo dietas com diferentes fontes de carboidratos associadas à ureia(2019-01-15) Silva, Letycia Cristine Fernandes Lira da; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/3420693856221234The objective of this study was to evaluate the digestibility of diets based on different sources of carbohydrates associated with high urea levels, replacing soybean in diets for sheeps. Four diets were tested with Tifton-85 hay (580 g/kg dry matter) as forage and corn+soybean; corn+urea; cassava scraping+urea and cactus pear+urea as concentrated ingredients. The experiment was carried out at the Animal Science Department of UFRPE. 40 male uncastrated sheep were used, distributed in random blocks, with four treatments and ten replications, housed in individual wooden stalls, equipped with feeder and drinking fountain. The duration of the experiment was 76 days, 20 of adaptation and 56 for data collection. The apparent digestibility (AD) assay was performed by the total fecal collection method. During the period of the digestibility test the feces were collected daily to determine the digestibility coefficients of dry matter, organic matter, crude protein, ethereal extract, neutral detergent fiber, total carbohydrates and non-fibrous carbohydrates. The apparent digestibility coefficients (ADC) were obtained by the relationship between the amount of ingested and excreted nutrients. The data were submitted to analysis of variance and the averages were compared by the Tukey test (P <0,05) procedure using the General Linear Models (GLM) of the Statistical Analysis System (SAS) program. The dry matter digestibility coefficients did not vary among the treatments, except for the animals that were fed with cactus pear+urea (59,66). The diet that contained cactus pear in its composition also provided lower digestibility of organic matter (62,92) and total carbohydrates (63,75), compared to corn+urea (69,50; 69,97) or cassava scraping+urea diets (70,47; 71,91). The crude protein digestibility coefficients were similar for the corn+urea, cassava scraping+urea and cactus pear+urea diets (78,54), being higher than the control diet (74,46). The digestibility coefficients of the ethereal extract were similar to each other in treatments corn+soybean and corn+urea (72,21) and similar to each other in the treatments cassava scraping+urea and cactus pear+urea (60,68). The digestibility coefficient of the non-fibrous carbohydrates was higher for the cassava scraping+urea diet (86,26). It is possible the total replacement of soybean by urea in the experimental diets, especially in the diet composed by the association of manioc and urea, which presented better overall response in the variables evaluated in relation to the apparent digestibility.
