Item Utilização da farinha integral de mosca-soldado-negra (Hermetia illucens, L., Diptera: Stratiomyidae) para suplementação de abelhas uruçu (Melipona scutellaris)(2024-02-27) Guedes, Marcelo Vasconcelos de Azevedo; Nascimento, Júlio Cézar dos Santos; http://lattes.cnpq.br/4343017315156292; http://lattes.cnpq.br/5243280023942732The main objective of this study was to evaluate the growth of hives of the species Uruçu Nordestina (Mellipona scutellaris) through their gross weight when using whole black soldier fly larva flour (Hermetia illucens) in their supplementary feeding during the period of 43 days with weekly weighings. This work combines the sustainable proposal with what is already concretely known in the literature regarding the use of black soldier fly insect flour, through a high concentration of crude protein (CP) and other nutrients (lipids, 18%, and protein content gross, varying between 42% and 75%,) applied in the supplementation of Uruçu Nordestina (M. scutellaris). The aim is to mitigate the impact of the decline in its beekeeping pasture in dry seasons, negatively influenced by the scarcity of its native flora, of which only 12.4% of the original remains. The experiment was carried out with 9 colonies arranged in northeastern boxes and subjected to 3 treatments (T1, T2, T3) with increasing levels of BSF protein, in the proportion of (14%, 28% and 42%) respectively. The Supplement was composed of corn bran, Apis mellifera honey (50%) and whole wheat flour (BSF) (50%), supplied “in natura” in a homogeneous and pasty mass; weighing (30g) each treatment. There was an increase in the consumption of diets and the weight of colonies supplemented with wholemeal BSF flour in the weekly collection of experimental data.; gradually. However, there was no statistical difference between treatments) in the weight analysis (p=0.4415) and in the consumption analysis (p=0.1115), upon completion of the data.Item Metabolizabilidade de nutrientes e energia dos resíduos da industrialização de biscoitos e bolachas e massas em frangos de corte(2023-04-21) Oliveira, Kássia Priscila Gomes Cabral de; Ludke, Maria do Carmo Mohaupt Marques; http://lattes.cnpq.br/4629657233206289The objective of this work was to determine the nutritional and energy value of waste from the biscuit and biscuit industry (RBB) and pasta (RM) in broiler chickens using the total collection method, using 1% of ferric oxide, as a marker of the beginning and end of collection. These residues come from the manufacturing industry of savory and sweet biscuits and macaroni, in which they are discarded and can pollute the environment, which were analyzed for the composition of dry matter (DM), crude protein (CP), ether extract (EE), Crude Fiber (FB), Ash (CZ), Non-Nitrogen Extractives (ENN) and Gross Energy (EB). A metabolism experiment was carried out with a total of 90 birds with an average initial weight of 481.510.50 g, to determine the coefficients of apparent metabolization of dry matter (CMAMS), crude protein (CMAPB) and gross energy (CMAEB), and the EMA (apparent metabolizable energy) and EMAn (apparent metabolizable energy corrected for nitrogen). The experimental design was completely randomized, with three treatments (T1 - nutritionally balanced reference ration composed of corn and soybean meal, T2 - 70% reference ration and 30% mass residue and T3 -70% reference ration and 30% biscuit residue and wafer) and six replications of five birds per experimental unit. Diets were provided ad libitum for a period of eight days, four days for adaptation and four days for total excreta collection. The results of the nutritional composition of the by-products were: RBB with 91.7% of DM, 8.34% of CP, 4333 of EB, 1.24% of EE, 1.65% of FB and 0.14% of CZ; andRM with 88.87% DM, 11.55% CP, 3882 EB, 0.92% EE, 1.3% FB and 0.74% CZ. The RBB EMA and EMEn values were 3959 and 3480 Kcal/kg; and RM of 3812 and 3616 Kcal/Kg.Item Efeito da inclusão de farinha de minhoca com e sem zeólita natural na dieta de tilápia (Oreochromis niloticus) sobre os parâmetros de carcaça(2022-10-07) Oliveira, Elton Francisco de; Ludke, Maria do Carmo Mohaupt Marques; http://lattes.cnpq.br/4629657233206289; http://lattes.cnpq.br/3930176884309812The purpose of this research is to evaluate the effect of the addition of earthworm flour and the inclusion of zeolite (clinoptilolite) on carcass composition parameters. In the experiment, 280 tilapia of the species Oreocrhomis niloticus were used, with an initial and final weight of 2.826±0.0896g and 13.59±0.75g, respectively. The treatments were 8 diets corresponding to a 4 x 2 factorial arrangement, with 4 levels of inclusion of earthworm flour (0, 3.5; 7.0 and 10.5%) and levels of 0 and 2% of zeolite (Clinoptilolite ), the fish were distributed in a randomized block design with 5 replications. The following parameters were evaluated: carcass yield (RC), carcass dry matter (MSC); carcass organic matter (MOC); Mineral Substrate Matter (MMC); carcass energy based on dry matter (EMSC); ethereal substrate extract (EEC); energy retention coefficient (CRE); crude carcass protein (CBP); RE= Energy retention coefficient; CRP= Protein retention coefficient; TEP= Protein Efficiency Rate; IHE= Hepatosomatic Index; IVS= Viscerosomatic Index; At the end of the experiment (85 days) the animals were stunned with eugenol and then sacrificed and frozen, later they were lyophilized for analysis. The data were submitted to analysis of variance, in order to observe the main effects and the interaction between the factors (Worm meal levels and Zeolite inclusion) on the composition and protein and energy retention in the fish body. All analyzes were performed using the GLM procedure of the SAS computational package, at a 5.0% significance level. According to the data, there was a significant reduction in the amount of lipdis (p=0.0208) and in the energy retention coefficient (CRE) (p=0.0376) in the carcass of these animals when adding Zeolite in the diets. As for earthworm meal, a significant effect (p=0.0500) on CRE was observed, where when performing the regression there was a linear increase (P=0.0188) when including this ingredient in the diets of these fish. With this, we can add up to 10.5% of earthworm meal in diets for Tilapia, however Zeolite reduced energy efficiency, not interfering with other carcassItem Parâmetros ruminais de ovinos e caprinos alimentados com silagem da mucilagem do desfibramento de sisal(2022-05-31) Miranda, Lucas Ramos de; Guim, Adriana; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/8413413377006449The following study aimed to evaluate the rumen parameters of sheep and goats submitted to diets based on sisal shredded mucilage (MUDS) ensiled with and without additives, recording the pH values, quantifying the concentrations of ammoniacal nitrogen in the rumen of animals, in addition to tests to analyze the rumen fluid, measuring the reductive activity of the rumen flora (methylene blue reduction test, PRAM) and the sedimentation time at different times (0, 2, 4, 6, 8 10 hours) after the morning feeding. The experimental diets were: a) Control (60% Tifton 85 hay (Cynodon dactylon, L.) and 40% concentrate); b) MUDS silage (SilMUDS) without additive (45% SilMUDS, 15% Tifton 85 hay and 40% concentrate); c) MUDS silage added with ground corn (SilMUDS-MI) - 45% SilMUDS-MI, 15% Tifton 85 hay and 40% concentrate; and d) MUDS silage with wheat bran (SilMUDS-TRI)) – 45% SilMUDS-TRI, 15% Tifton 85 hay and 40% concentrate. The proportions of additive in the silages were 75% of the MUDS and 25% of the additive. Four sheep and four male goats, castrated and cannulated in the rumen, with initial mean body weights (BW) of 71.05 ± 7.53kg and 57.41 ± 9.71kg, respectively, distributed in a Latin square design were used. Ruminal parameters were influenced with the use of silages; pH and ammonia nitrogen showed greater variation (P<0.05) for the effect of treatments and collection time after the first feeding, resulting in ideal levels according to the literature for N-NH3 present in the rumen. Low levels of pH were obtained in all treatments and collection hours, evidencing the treatment of SilMUDS-MI which resulted in the lowest level (5.97); The sedimentation test showed a significant effect (P<0.05) for the hours of collection, with its sedimentation time decreasing as the hours of analysis passed; the analysis of PRAM (Methylene Blue Reducing Test) showed a high reductive effect (P<0.05) observing the collection times, due to the high level of carbohydrate degradation present in the rumen and how acidic the rumen fluid was. The SilMUDS with additives or not provides good levels of ammonium nitrogen considering normal ruminal parameters. SilMUDS, with or withoutItem Substituição do milho moído por gérmen integral de milho extra gordo em dietas para ovino(2021-02-02) Matos, Yasmin Caroline da Silva; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736; http://lattes.cnpq.br/4404627710797961The objective was to evaluate the effects of the inclusion of whole wheat germ in extra fat to replace ground corn in the sheep diet. Five crossbred mixed breed (SRD) sheep, castrated, fistulated and cannulated in the rumen, with initial mean body weight (BW) of 67.56 ± 9.13 kg were used, distributed in a 5x5 Latin Square experimental design. The roughage used were corn silage and forage palm, small cultivar and the treatments consisted of five replacement levels of ground corn with extra fat whole corn germ (0; 25; 50; 75; and 100%) in the concentrate. Consumption of MS, in kg / day and g / kg of CP, and that of MO, PB, NDT, FDNcp and CNFcp, expressed in kg / day, were not influenced by the replacement of ground corn with whole germ of extra fat corn. EE consumption increased linearly (P <0.05), as there was an increase in corn germ in the diet. With the replacement of ground corn with extra fat whole corn germ, there was no effect on the apparent digestibility coefficients of MS, MO, FDNcp. While the apparent digestibility coefficient of ether extract was linear, due to the dilution effect that diets with high EE content present. There was also a significantly increasing effect on the apparent digestibility of PB, since there was a smaller amount of PB excreted in the faeces. There was no significant effect on the time spent on food, rumination and leisure. The ruminal pH was not influenced by the replacement of ground corn with extra fat whole corn germ. Above all, it showed quadratic behavior throughout the collection hours. There was no effect of substitution on ammoniacal nitrogen (NAR) concentrations; however, decreasing linear behavior was observed due to the collection times and interaction of the replacement levels and the collection time. Quadratic behavior was also observed for acetate, and a decreasing linear effect for butyrate. The acetate and propionate concentrations, the total AGV and the acetate: propionate ratio showed quadratic behavior, depending on the collection times. In view of the results, it is recommended to partially replace ground corn with extra fat whole corn germ in the sheep diet.Item Avaliação nutricional do resíduo de biscoito para a alimentação de suínos em crescimento(2021-02-26) Carmo, Matheus Rocha do; Dutra Junior, Wilson Moreira; http://lattes.cnpq.br/5594343814011398; http://lattes.cnpq.br/1116419112841949The objective of this study was to evaluate the residue of the cookie industry for growing pigs. A physical-chemical analysis of the cookie waste (RB) was performed to determine its composition, then a digestibility trial was developed to determine the digestibility coefficients of dry matter (DM) and crude protein (CP). For this, 16 castrated male Landrace x Moura crossbred pigs were kept in metabolism cages, grouped in an entirely randomized design with two treatments (control diet and diet with 40% cookie waste substitution), eight repetitions and one animal per experimental unit in the growth phase (mean initial weight of 34.68 ± 4.14 kg). The experimental period consisted of 14 days, with the first 7 days for adaptation to the cage and feed, and the last 7 days for collection. During this period the animals received water and feed twice a day. Dry matter digestibility, crude protein digestibility and digestible protein were evaluated. The cookie residue presented 90.47% DM, 4.59% CP, 14.80% EE, 1.94% CZ. The gross energy of the cookie residue was 4061 kcal/kg, while the DP was 90.61%. The apparent digestibility coefficients of the cookie residue showed 94.24% CDAMS and 90.21% CDAPB. The results of chemical composition and nutrient digestibility allow us to conclude that the industrial cookie residue has the potential to be used in the feeding of growing pigs.Item Glicerina bruta na dieta de caprinos confinados: características de carcaça e de perna(2019-02-01) Cordeiro, Eduardo Henrique Araújo; Véras, Antonia Sherlânea Chaves; http://lattes.cnpq.br/0074248045711399; http://lattes.cnpq.br/9903022769655568Goat farming is a widespread activity in the Brazilian semi-arid region. The goat has great adaptation to the climate of this region, which suffers with irregularity in the rains, damaging the production of forage resources. The practice of confinement is an option of the producer to minimize food shortages, implying higher food costs. With increasing supply, crude glycerin (GB) becomes an alternative ingredient in the diet formulation of these animals. The objective of this study was to evaluate the carcass and leg characteristics of goats confined when fed with different levels of crude glycerin (0, 6, 12 and 18%) in the diet. A total of 40 goats were used, with no defined racial pattern, with a mean initial weight of 19.52 ± 2.35 kg, divided into four treatments with 10 replicates, using a completely randomized design. In 58 days of evaluation, the consumption and leftovers of these animals were recorded daily, and food samples and leftovers were collected for bromatological analysis to determine dry matter intake (DMI). At the end of the experimental period, slaughtering was carried out to determine the carcass and leg characteristics of the animals. The content of the gastrointestinal tract increased according to higher levels of GB. The empty body weights; hot and cold carcass weight and their yield; the loin eye areas; and the weights of the reconstituted leg and respective muscles and bones, decreased linearly. The inclusion of GB with low glycerol (63.06%) in up to 18% in DM in the goat diet compromises the main characteristics of the carcass and leg of the animals.Item Resíduo da indústria de doces em associação à Protenose® na alimentação de pequenos ruminantes fistulados: consumo e digestibilidade(2019-01-18) Silva, Dijaina Ferreira da; Véras, Antonia Sherlânea Chaves; Almeida, Marina de Paula; http://lattes.cnpq.br/7584834665120683; http://lattes.cnpq.br/0074248045711399; http://lattes.cnpq.br/7458404797378748The objective of this study was to evaluate the effect of different levels of residues from the candy industry in substitution of corn for the feeding of small ruminants, on consumption and apparent digestibility of dry matter and its components. 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 Desempenho de frangos de corte de 1 a 21 dias alimentados com rações contendo farelo residual de milho com e sem enzimas(2019-01-15) Antunes, Larissa Rayane; Ludke, Maria do Carmo Mohaupt Marques; http://lattes.cnpq.br/4629657233206289; http://lattes.cnpq.br/8292412515130779The objective of this research was to evaluate the effect of experimental diets containing different levels of inclusion of residual corn bran (FRM) supplemented or not with enzymatic complex, through performance parameters in broilers from 1 to 7 and from 8 to 21 days of age. The FRM is a product resulting from the processing of maize for the generation of by-products destined for human consumption, being an ingredient with the potential to make up the rations of broiler chickens used by producers in the Northeast region. The treatments were diets included levels of FRM, without and with enzyme (S/E and C/E): 0% FRM S/E, 0% FRM C/E; 18% FRM S/E; 18% FRM C/E; 36% FRM S/E; 36% FRM C/E; 54% FRM S/E; 54% FRM C/E. A total of 1536 male chicks of the commercial strain Ross 308 (AP95) from 1 to 21 days of age were housed in boxes, in a 4x2 factorial arrangement (four inclusion levels of FRM x without and with enzyme), eight replicates with 24 birds per unit experimental. The performance variables were daily mean weight gain (GPMD), mean daily feed intake (CMDR) and feed conversion (CA) in stages 1 to 7, 8 to 21 and in the total period of 1 to 21 days. The FRM can be used up to 54% in diets for broiler chickens from 1 to 21 days of age without affecting the performance parameters of the animals, and supplementation of the enzymatic complex in the experimental diets resulted in improved feed conversion of the ingredients present in the feed.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.
