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 Avaliação da digestibilidade de farinha de cefalotórax de camarão (Penaeus vannamei) em dietas para tilápia (Oreochromis niloticus)(2023-09-22) Campelo, Kesya Leal; Santos, Juliana Ferreira dos; http://lattes.cnpq.br/6621907859216486; http://lattes.cnpq.br/2587814165212462In order to promote knowledge about alternative ingredients for aquatic animal feed formulations, the apparent digestibility coefficients (ADC) of protein, dry matter and crude energy of two ingredients in tilapia feed were determined. Seventy-two juvenile Nile tilapia (Oreochromis niloticus) with an average weight of 61.85±10.06 g were used in a completely randomized experimental design with three treatments, three replications and eight fish per box, alternating between the box and the hatchery. Three treatments were used: Reference feed, based on the nutritional needs of the species; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) whole with reference feed; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) with low fat content. The ADC was determined by the indirect method using 1% celite as an inert indicator. The CDA for crude protein was 94.14% and 94.22% and digestible values for crude protein were 51.96% and 56.90%; for dry matter, 92% and 91.8%; for energy, 92%; and digestible values of 80 and 89% were found. Shrimp cephalothorax waste was considered a potential substitute for protein in feed for the species.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 Escondidinho de jaca verde: desenvolvimento de produto(2022-10-07) Silva, Maria Eduarda Nascimento da; Panetta, Monica Helena; http://lattes.cnpq.br/0760135351368402Item Desenvolvimento e aceitabilidade de brownie low carb(2021-03-02) Souza, Sérgio Luiz Tavares de; Panetta, Monica Helena; http://lattes.cnpq.br/0760135351368402; http://lattes.cnpq.br/8427817147720123Item Desenvolvimento e análise física de pão sem glúten com diferentes fermentos(2022-05-26) Ferreira, Pedro Vinícius Duarte; Panetta, Monica Helena; http://lattes.cnpq.br/0760135351368402; http://lattes.cnpq.br/9220472695228796Item Desenvolvimento de brownie vegano com utilização de géis de chia e linhaça(2021-03-05) Silva, Carla Vivianne Santos; Costa, Ana Carolina dos Santos; http://lattes.cnpq.br/8927435119035218Item 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.
