The study aimed to investigate the effect of dietary supplementation with palm oil on serum lipid profile, the seminal characteristics of buffaloes (Bubalus bubalis) and the correlations between them. Twelve bulls were divided into Group CONT (n = 5) or Group OIL (n = 7). Animals in both groups were fed with isoproteic diets composed of corn silage and concentrated (ground corn, wheat bran and urea), with 50% forage/concentrate ratio, during 130 days (Periods 1 and 2). Palm oil (2%DM) was added to diet offered to Group OIL. Semen and blood samples were collected every two weeks. Increased serum levels of cholesterol, HDL and total lipids were observed for Group OIL, while the period influenced on cholesterol, LDL, total lipids and VLDL (P<0,05). Treatment decreased gross motility (P<0.05) and slightly reduced sperm membrane integrity (P<0.05) in animals of Group OIL. There were significant correlations between triglycerides and minor defects (r=-0.412, P=0.006), LDL and total defects (r=-0.333, P=0.030), total lipids and minor defects (r=-0.366, P=0.017), VLDL and spermatic viability (r=0.381, P=0.012), and total lipids and totals defects (r=-0.309, P=0.046), highlighting positive effects of higher lipid serum levels on sperm morphology and viability. The incorporation of palm oil in the diet altered the serum lipid profile, but it showed no positive effect on seminal parameters related to the potential of bull fertility.

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/8389692203753236
This 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.

(Universidade Federal do Pará, 2011-10-19) SANTOS, Alessandra Ximenes; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236; http://lattes.cnpq.br/2919433679918544; LOURENÇO JÚNIOR, José de Brito; GARCIA, Alexandre Rossetto; http://lattes.cnpq.br/2678267039338224
The byproducts coconut meal (FC) and palm kernel cake (TAD) available in agribusiness in Eastern Amazonia can be used as alternative foods in the substitution of conventional concentrates. However, little information about their chemical composition and their relationship with productive and reproductive performance of the animals is available. Thus, the aim of this study was to evaluate the effect of the feeds prepared with coconut meal and palm kernel cake over the semen quality of buffaloes. Also, the individual daily feed intake in the experimental diets and your relationship with the testosterone levels, scrotal circumference and semen quality were analyzed. The experiment was developed in the Animal Research Unit "Senador Álvaro Adolpho", in Embrapa Eastern Amazon, Belém-PA. Fifteen buffaloes (Bubalus bubalis) bulls with age of 3.2 ± 1.8 years and weights of 578.6 ± 101.9 kg were used as semen donors. The animals were separated in three groups: the Control group, the FC-Base group (coconut meal-based) and the TADBase group (palm kernel cake-based). The supplementary feeding was available individually every day, according 1.0% of body weight (BW). Semen collections (n=173) were realized weekly, and they started 112 days after initiation of supplementary feeding, after two spermatogenic cycles. Seminal physical characteristics (aspect, color, volume, concentration, pH, sperm motility and vigor) and morphology (defects and integrity of sperm plasma membrane) were analyzed. The EPA method (1974, 1994, 2009) was used to determine the macronutrients, micronutrients and toxic metals in diets. Data were submitted to ANOVA and the means compared by Test t (P<0.05). The average feed intake was 4.778 ± 1.233 kg in the Control, 3.112 ± 0.693 kg in the FC-Base, and 4.558 ± 1,077 kg in the TADBase. The means of weight were 591.4 ± 103.3 kg, 566.4 ± 94.1 kg and 578.3 ± 107.5 kg and the scrotal circumference of 34.6 ± 2.0 cm, 33.0 ± 1.9 cm e 32.7 ± 1.9 cm for Control, FC-Base and TAD-Base, respectively. The spermatic concentration (x106 sptz/mL) was 1326.3 ± 893.8, 1698.1 ± 1023.0 e 1003.2 ± 569.0 for Control, FC-Base and TAD-Base, respectively. In the same order, the integrity of sperm plasma membrane (%) observed was 68.0 ± 19.5, 72.0 ± 22.6 and 82.1 ± 12.2. The progressive sperm motility (0-100%) presented significant difference (P<0.05) in the TAD-Base group (71.7 ± 15.1%), compared to Control (59.3 ± 20.5%) and FC-Base (56.7 ± 24.8%). Correlations were observed between the variables of response. The feed intake and your components, such as crude protein, lipids, macronutrients, micronutrients and toxic metals were higher in the TAD-Base group, exception to K and Ti, higher in the Control and the FC-Base group, respectively. No significant differences (P>0.05) were observed in semen aspect, volume, mass activity, spermatic vigor, pH and sperm pathologies. However, higher sperm concentrations were observed in FC-Base and increased motility and integrity of sperm plasma membrane in the TAD-Base. Thus, it can be concluded that diets based on byproducts of the agribusiness, such as coconut meal and palm kernel cake, can be used for buffalo bulls, however, the better semen quality was observed in diets based on palm kernel cake.

Efeito da utilização do óleo de dendê na dieta sobre a qualidade do sêmen in natura de búfalos (Bubalus bubalis) criados em Belém, Pará
(Universidade Federal do Pará, 2012-08-23) SILVA, Geanne Rocha da; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236; http://lattes.cnpq.br/2919433679918544; LOURENÇO JÚNIOR, José de Brito; GARCIA, Alexandre Rossetto; http://lattes.cnpq.br/2678267039338224
The objective of this study was to evaluate the effect of incorporation of palm oil on serum lipid levels and sperm quality of buffalo bulls, since research about palm oil seed for reproductive purposes are scarce. The study was conducted at Embrapa Eastern Amazon, and used 12 pre-selected buffalo bulls, with a mean age of 3.47 ± 0.92 years and weight of 456.8 ± 50.4 kg. The bulls were fed and divided into two groups according to diet received. Diets were isoproteic (cracked corn, wheat bran and corn silage; proportion roughage / concentrate 50%) and were offered in collective pens. Animals of CONT Group (n = 5) received a control diet and OIL Group (n = 7) received the same diet with addition of 2% of palm oil on the DM. Analyses were performed using chemical and fatty acid profile of foods. Serum lipid profile, physical and morphological features of raw semen were investigated, including the relations between them. Statistical analysis included analysis of variance (ANOVA), comparison of means by Tukey test and Pearson correlations (P <0.05). Increased lipid consumption was noted related to saturated fat acids (71.23%) and unsaturated fat acids (55.40%) in OIL Group. Significant effects for serum parameters were observed for triglycerides, cholesterol, HDL and total lipids, with higher values for the OIL Group, and significant effects over time for cholesterol, LDL, VLDL and total lipids (P <0.05). Regarding to semen parameters, there was a significant reduction in gross motility and integrity of plasmatic membrane, and reduced seminal concentration on the period for the OIL Group. There was significant correlation between the variables: triglycerides and minor defects (r = -0412, P = 0.006), LDL and total defects (r = -0.333, P = 0.030), VLDL and viability (r = 0.381, P = 0.012), total lipids and minor defects (r = -0366, P = 0.017), and total lipids and total defects (r = -0.309, P = 0.046). Although an observed relationship between higher levels of serum lipids and better sperm morphology, and no reduction of fresh semen quality by palm oil addition below the physiological levels, the use of 2% of palm oil in the diet did not improve effectively the parameters related to semen quality and bulls fertility.

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/8389692203753236
This 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.

(Universidade Federal do Pará, 2011-07-18) AMARAL JÚNIOR, João Maria do; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236; BERNARDES, Thiago Fernandes; http://lattes.cnpq.br/9614321233731548
The dairy buffaloes production in the State of Pará, which has 51% of national buffalo herd, has been seeking alternatives to increase the productivity of systems, which are based on the use of pasture as a food source. In this context, the objective of this study was to evaluate the performance off buffalo heifers grazed in marandu grass and supplemented with different strategies. A total of 48 heifers and average initial age of 12 months and weight of 207,0 kilograms were distributed in a completely randomized design with four treatments and two replications. The experimental diets were supplemented with a base of coconut meal (COC), the second base of palm kernel cake (DEN), third with corn and soybeans (FS + M) as positive control and a fourth treatment using mineral mix (MM) as a negative control. The animals fed the supplements COC, DEN e M+FS provided additional daily gain of 0,399, 0,405, 0,319 kg / animal, respectively, compared to the control group (P<0,05). The treatment on coconut got the best economic value when compared to other treatments. Dietary supplementation of buffalo heifers grazed in the dry period within use of by-products provides similar gains with the binomial corn and soybean meal and additional when compared to the mineral salt at a lower cost, resulting in increased productivity, sustainability and revenue of the activity.

(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/8389692203753236
This 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.

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/8389692203753236
Assesses 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.

Production and chemical composition of three sugarcane cultivars grown under Af climate conditions
(Universidade Federal do Pará, 2015-11) MIRANDA, Augusto Sousa; DOMINGUES, Felipe Nogueira; GODOY, Bruno Spacek; OAIGEN, Ricardo Pedroso; RÊGO, Aníbal Coutinho do; FATURI, Cristian; CORRÊA, Renato Pinto; SILVA, Flavio da
The objective of this study was to evaluate the chemical composition and yield of three sugarcane cultivars grown under Af climate conditions. Three sugarcane cultivars were examined, namely, IACSP93-6006, RB83-5486, and SP79-1011, in a randomized block design with three treatments, four blocks, and two replicates per block; means were compared using Tukey’s test at 5% probability level. Significant differences were observed for dry matter, ether extract, crude protein, acid detergent fiber, lignin (LIG), cellulose, neutral detergent fiber corrected for ash and protein (NDFap), total carbohydrates, carbohydrate fractions B2 and C, and dry matter yield. The fiber components (NDFap, LIG, and fraction C) displayed low values. The cultivars produced high dry matter yields, especially IACSP93-6006 and SP79-1011. There were no differences among sucrose (Pol) values and the NDF/Pol ratios. The low Pol values indicate that sugarcane grown under Af climate conditions does not produce high levels of sucrose. The three sugarcane cultivars grown under the Af climate conditions produce high yields of DM/ha but low concentrations of the fiber components, as well as low Pol concentrations.

Valor nutritivo da torta de castanha-do-pará (Bertholletia excelsa Bonpl.) para alimentação de ruminantes
(Universidade Federal do Pará, 2014-02-28) RAMOS, Aline Fernanda Oliveira; SILVA, André Guimarães Maciel e; http://lattes.cnpq.br/8940750096354420; FATURI, Cristian; http://lattes.cnpq.br/8389692203753236; LOURENÇO JÚNIOR, José de Brito; http://lattes.cnpq.br/2919433679918544
Nutrition is one of the most important links of the production process, either by the costs involved or by establishing the efficiency and productivity of the animal. At the same time the brazilian agricultural industry lies in the expansion with the use of oil, especially in the cosmetic and biodiesel sector, which generates waste due to obtain oil process. Thus, the use of these by-products in animal feed is an alternative for both activities, since for livestock food option means good availability and low cost, and for agribusiness means reducing accumulation and inadequate destinations of their waste. Before using a new food in feed formulations, experimental measurements are necessary to determine the chemical composition and evaluate the responses of animals that received the new the ingredient in its diets, as the voluntary intake, nutrient digestibility and animal’s behavior, which is important to complement and strengthen the nutritional data, especially because they represent the effects of the quality of food in the digestive activities. Thus, the byproduct of the processing of the almond brazilian nut and its effects on voluntary intake, digestibility and feeding behavior displayed by sheep fed with increasing levels of inclusion, 0, 15, 30 and 60% in the diet based on corn silage were assessed. Sixteen males lambs, uncastrated at 33 kg average were used, kept in individual metabolic cages, which received the diet in two meals, at 8a.m and 6p.m, with the offer set to allow 15% on the remains. Samples of the remains and feaces were collected and analyzed to determine the consumption and digestibility of nutrients. For four days the animals intake behavior were evaluated in relation to their activities of feeding, ruminating and idling, occurrences and duration of ruminated bolus and rumination chewing, and the efficiency of feeding and ruminating. The Brazil’s nut (BN) is a by-product with potential for ruminant nutrition, with considerable amounts of proteins and lipids, but due to its high content of ether extract in inclusion levels higher than 16.3% of the maize diet, affect rumen fermentation, especially fiber digestibility, the dry matter intake and the ruminating time in the animals.
