    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/8413413377006449
    The 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 without

    Substituição da silagem do resíduo da cultura do abacaxi por palma forrageira na dieta para ovinos
    (2021-02-25) Damas, Luciana Pereira; Ferreira, Marcelo de Andrade; http://lattes.cnpq.br/4818123702136736; http://lattes.cnpq.br/1935877952205692
    The objective was to evaluate the partial replacement of the pineapple cultural residue silage (SRCAB) by forage palm (0; 29.2; 58.4 and 87.6%), in addition to a control diet with sorghum silage as exclusive roughage, diet for sheep on consumption, apparent digestibility, ingestive behavior. Five crossbred male sheep with an average body weight of 40 kg were used, distributed in a 5 x 5 Latin square, with five animals, five treatments and five experimental periods. The consumption of DM and MO were higher for the levels: 0; 29.2; 58.4; 87.6% substitution in relation to the control diet. Regarding the consumption of CP, at the replacement levels 0, 29.2 and 58.4% it was higher than the control. There was less consumption of NDF for the levels 58.4 and 87.6% in relation to the control diet, for the other levels the consumption was similar. For all substitution levels, the consumption of CNF was higher, compared to the control diet. The consumption of MS, MO, PB, FDN, CNF and NDT decreased linearly due to the replacement of SRCAB by forage palm. The digestibility of DM in relation to the control diet showed to be higher in all levels of substitution by palm, however, in relation to the digestibility of CP only in the substitution levels of 58.4 and 87.6% was higher than the control diet. As for the replacement levels, there was no change in the digestibility of nutrients. The feeding time was similar between all levels of substitution in relation to the control treatment, however the time spent with leisure was longer and the time of rumination less responses were observed, respectively; to the levels of 29.2; 58.4 and 87.6% of inclusion, respectively; due to the replacement of SRCAB by forage palm. SRCAB showed better nutritional value than the silage of the forage sorghum variety BRS Ponta Negra. The inclusion of forage palm to replace the silage of pineapple crop remains is not recommended, mainly because it reduces energy consumption.
