Item Acesso aberto (Open Access) Avaliação do ganho de peso e aspectos reprodutivos de primíparas zebuínas suplementadas com uréia no período seco(Universidade Federal do Pará, 2009) CARDOSO, Robson Pinto; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236This study aimed to evaluate the productive and reproductive performance of cow cutting, supplemented with urea in the dry season. We used 58 females Tabapuã x Nellore crossbred, pregnant, with a mean age of 39 months and average weight of 399 kg. The worm and experimental animals were divided into two groups, in an area of 50 ha of grass Brachiaria brizantha cv Marandu, with 25 ha for each group, one group (A) supplemented with mineral and another (B) with mineral enriched with urea, the ratio of 80:20 (salt: urea). During the months of August-November, when most of the year in the dry, the grass had on average 5,800 kg of dry matter per hectare to 6.2% crude protein. These mixtures were administered in mineral cochos covered in order to meet ad libitum consumption during the dry period. The experimental design was completely randomized to two treatments. Difference was observed for final body weight (PVF) between the treatment with salt and mineral supplementation with urea, with average values of 360.1 kg and 385.8 kg, respectively. Difference was also observed for average daily gain, with an average of 0.465 kg/an/day for the treated group and 0.284 kg/an/day for the control group, postpartum with a gain of 41.2 and 26.5 kg/animal, respectively. The best performance of the supplemented animals should be related to the increase in dry matter intake promoted by supplementation with urea (12.610 kg to 8.744 kg). The best body growth (weight and body score) to the beginning of the amounts reflected in the expression of heat these animals, whereas 75% of cows supplemented with urea had expressed estrus during the first 60 days from the amounts to only 53, 33% of nonsupplemented. When we evaluated the whole period from the mount was not observed difference between the expression of estrus in females supplemented or not, a fact related to good body score submitted by the end of the animal to mount, 3.7 in females supplemented and 2, 9 in non-supplemented.Item Acesso aberto (Open Access) Emulsificante em dietas para frangos de corte com diferentes fontes lipídicas(Universidade Federal do Pará, 2015-11-04) TAVARES, Fernando Barbosa; LIMA, Kedson Raul de Souza; http://lattes.cnpq.br/7607189403583641; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236This study aimed to evaluate the effects of diets containing different lipid source and the inclusion of an emulsifier (soy lecithin and polyethylene glycol ricinoleate) for broilers. Article I aimed to evaluate the influence of different fat sources in the metabolization of nutrients and serum broiler profiles, with the addition of emulsifier. 336 chicks were used in a 4x2 factorial arrangement, with eight replications and four lipid sources (soybean oil, Poultry Oil, Fish Oil and Tallow Beef) and 2 types of inclusions (not including the product and 5 g / kg emulsifier). Proceeded metabolic tests by the total collection method. The data were subjected to analysis of variance in SAS and the means were compared by Tukey test, the significance of P <0.05. No difference was observed for feed intake, metabolization coefficient of dry matter and crude protein. The coefficient of metabolizable ether extract (CMEE) was lower in the diets of fat (P <0.001). The lipid source modifies the metabolization of diets. The emulsifier, the tested values, does not modify the metabolization of ingredients and does not modify the HDL serum parameters, LDL, Cholesterol and Triacilglerol. For Article II aimed to test how the addition of emulsifier can alter the performance parameters, metabolization, carcass composition and economic viability for broiler diets with poultry oil and beef tallow. Diets with poultry oil (OA) or tallow (SB), in treatments to control (CON), other diets with reduction of 0.83 MJ / kg of metabolizable energy (RED) and diets with reduced MS and inclusion of 0, 1% inclusion of emulsifier (Emul). Diets with poultry oil performed better on average weight and feed intake, resulting in a reduction in the amount of crude protein in the carcass of 58.3% to 56.1% in diets with SB and OA respectively. The results indicated that the emulsifier reduced metabolization of ether extract, but increased the EMA in the diet with beef tallow in 0.93 MJ / kg. The emulsifier added in the form proposed only increased the cost of diet without significant result on performance, metabolism and body composition of broilers.Item Acesso aberto (Open Access) Óleo de fritura residual na alimentação de ovinos: consumo e digestibilidade(Universidade Federal do Pará, 2014-08-27) OLIVEIRA, Cristiane do Socorro Barros de; RÊGO, Aníbal Coutinho do; http://lattes.cnpq.br/4330113577933018; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236This study aimed to evaluate the effect of inclusion of residual frying oil consumption and digestibility of dry matter and nutrients in the diet and nitrogen balance. In consumption test and the apparent digestibility was used 20 Santa Inês lambs, with an average age of 90 days and average body weight of 19.29±3.17 kg, in a completely randomized design. The experimental period lasted 19 days, 14 days of adaptation and five total collection of the diets fed, orts, feces and urine. The total collection of feces was performed on plastic collectors and weighed daily. Urine was collected in plastic buckets and added daily in collectors hydrochloric acid 10%. The animals were housed in individual metabolic cages and fed twice daily with diets based on roughage and concentrate (50:50), while residual oil was included in the diet at concentrations of 0; 2; 4; 6 to 8% of the dry matter of the concentrate. The addition of the residual frying oil had no significant effect (p>0.05) on dry matter (DM), crude protein (CP), organic matter (OM), neutral detergent fiber (NDF), detergent fiber acid (FDA), total carbohydrate (TC), non-fibrous carbohydrate (NFC). However, consumption of lipids (EEC) increased linearly with the inclusion of oil in the concentrate, Y=0.0244 + 0,0051X (p<0.01). Also, there was no effect on the digestibility of DM, CP, OM, NDF, ADF, CNF and TCHO and nitrogen balance. The digestibility of EE increased linearly with the addition of oil in the diet, Y = 83.68 + 1,66X (p<0.01). The inclusion of the residual frying oil in the diet of sheep, in the inclusion of up to 8% of dry matter in the concentrate can be used without damage to the intake and digestibility of nutrients.Item Acesso aberto (Open Access) Potencial nutritivo da torta de dendê na alimentação de ruminantes no estado do Pará(Universidade Federal do Pará, 2010-06-23) VASCONCELOS, Helbilena Gildeli Rodrigues; ÁVILA, Sandra Cristina de; http://lattes.cnpq.br/9683521652094464; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236Assesses the effects of inclusion of palm kernel cake in the diet of growing sheep reared under tropical conditions, with emphasis on effects on intake, digestibility and performance of ruminants. For testing the intake and digestibility was used 16 Santa Inês sheep, with a mean age of 3 months and weighing approximately 19 kg during 19 days, 14 of adaptation and five days of collecting data and samples from metabolic cages. And for performance, with 15 male 4 months old, the same breed, weighing approximately 20 kg for 56 days, distributed in a randomized blocks with four treatments: 0, 25, 50 and 75% inclusion of palm kernel cake in the concentrate, diets composed of 40% (dry matter basis) of silage, elephant grass (Pennisetum purpureum) and 60% concentrate consisting of corn, soybean, palm kernel cake and minerals. The result showed a linear reduction in dry matter intake with the inclusion of palm kernel cake, but there was no statistically significant difference in dry matter digestibility. It was also noted an increase in digestibility of NDF and ADF in diets with higher proportions of palm kernel cake. In the performance test, there was a linear reduction in weight gain of animals as it raised the level of palm kernel cake in the diet, the result of lower dry matter intake (p <0.05) and worse feed conversion. The palm kernel cake is potentially productive, with high dry matter availability and good nutritional value. It is a good alternative to be used as a food supplement for sheep, but at higher levels can reduce animal performance, and its use depends on the purchase price and cost: benefit.
