The crude glycerin reduces losses fermentative and improves the nutritional value of marandu grass silage in a semiarid region / A glicerina bruta reduz perdas fermentativas e melhora o valor nutricional da silagem de capim marandu em uma região semiárida

The ensiling of marandu grass at the recommended time of management results in low dry matter (DM) content and nutritional value, but the addition of crude glycerin can compensate for these deficits if used during ensiling. Thus, the aim of this study was to evaluate the best level of inclusion of crude glycerin that can improve fermentation and the nutritional value of silages prepared with Urochloa brizantha cv. Marandu. The treatments consisted of five levels of inclusion of crude glycerin (0, 7.5, 15, 22.5, 30% of fresh forage) during ensiling of marandu grass with eight replications following the completely randomized design. For the evaluation of ruminal kinetics, four crossbred steers were used, cannulated in the rumen, following a randomized block design in a split plot scheme. For the percentage unit of inclusion of glycerin, there was a linear reduction of 0.34% in gas losses and increase of 0.45% and 0.55% in the recovery of DM (P <0.01) and in the DM content (P <0.01), respectively. The inclusion of up to 22.5% of crude glycerin in the silage of marandu grass is recommended to reduce losses during fermentation and improve the recovery of dry matter and the nutritional value of silage

Objective: Report a clinical case of a restorative treatment for LCNC. Methodology: Case report of a descriptive qualitative type according to the ethical principles that govern research with human beings present in the Declaration of Helsinque. Case Report: A 34-year-old male patient, leucoderma, sought care at the Dentistry Clinic of the Tiradentes University Center - UNIT/AL complaining of dentinsensitivity. During the anamnesis, he reported ingesting acidic foods frequently, performing toothbrushing right after meals and having used orthodontic appliance for about two years. On clinical examination, the presence of LCNC was identified in elements 15 and 16. Therefore, the restorative treatment was discussed and accepted by the patient, and the resin composed of the nano-hybrid type was the material of choice. Final considerations: The treatment of LCNC is based on the control of etiological agents and restorative protocol, being preferable the use of composite resins and self-condidiator adhesives.Objetivo: Notificar un caso clínico de un tratamiento restaurador para la LCNC. Metodología: Reporte de caso de tipo descriptivo cualitativo según los principios éticos que rigen la investigación con seres humanos presentes en la Declaración de Helsinque. Informe del caso: Un paciente masculino de 34 años, leucoderma, buscó atención en la Clínica de Odontología del Centro Universitario Tiradentes - UNIT/AL que se queja de dentinasese a la sensibilidad. Durante la anamnesis, informó que ingería alimentos ácidos con frecuencia, realizando el cepillado de dientes justo después de las comidas y habiendo utilizado aparato de ortodoncia durante unos dos años. En el examen clínico, se identificó la presencia de CNCL en los elementos 15 y 16. Por lo tanto, el tratamiento restaurador fue discutido y aceptado por el paciente, y la resina compuesta del tipo nano-híbrido fue el material de elección. Consideraciones finales: El tratamiento de LCNC se basa en el control de agentes etiológicos y protocolo restaurador, siendo preferiblemente el uso de resinas compuestas y adhesivos autocondiadores.Objetivo: Relatar um caso clínico de um tratamento restaurador para lesões cervicais não cariosas (LCNC). Metodologia: Relato de caso do tipo do tipo qualitativo descritivo de acordo com os princípios éticos que regem a pesquisa com seres humanos presentes na Declaração de Helsinque. Relato de caso: Paciente gênero masculino, 34 anos de idade, leucoderma, procurou atendimento na Clínica de Odontologia do Centro Universitário Tiradentes – UNIT/AL queixando-se de sensibilidade dentinária. Durante a anamnese, relatou ingerir alimentos ácidos com frequência, realizar escovação dentária logo após as refeições e ter utilizado aparelho ortodôntico por cerca de dois anos. Ao exame clínico, foi identificado presença de LCNC nos elementos 15 e 16. Logo, o tratamento restaurador foi discutido e aceito pelo paciente, sendo a resina composta do tipo nano-híbrida o material de escolha.  Considerações finais: O tratamento das LCNC baseia-se no controle dos agentes etiológicos e protocolo restaurador, sendo preferível o uso de resinas compostas e adesivos autocondiocionantes

Use of banana (Musa sp.) pseudostem hay in feedlot sheep feeding

The objective with this study was to evaluate intake, feeding behavior, rumen fluid characteristics, performance, and nutrient digestibility of sheep fed banana pseudostem hay (BPH) with and without virginiamycin (VM). Thirty-two uncastrated male crossbred Dorper × Santa Inês lambs at approximately five months of age, with an average initial body weight of 25.00±1.95 kg, were used in the experiment. Four diets were tested, as follows: Tifton grass hay (TGH) plus concentrate with VM; BPH replacing 60% of TGH plus concentrate with VM; TGH plus concentrate without VM; and BPH replacing 60% of TGH plus concentrate without VM. The experiment was set up as a completely randomized design in a 2×2 factorial arrangement, in which the factors were represented by BPH and TGH with and without VM, organized in an orthogonal contrast. Banana pseudostem hay inclusion influenced nutrient intake, except for non-fibrous carbohydrates corrected for ash and protein. Neither idling nor water intake times were changed by VM inclusion or banana pseudostem hay addition. Rumen fluid pH did not differ among the contrasts (THV+BHV) vs. (TH+BH), THV vs. TH, and BHV vs. BH, which were used to evaluate VM influence. Banana pseudostem increased rumen fluid pH in the contrast THV vs. BHV, both treatments including VM. Mean temperature of rumen fluid was 34.07 °C, and it did not change by inclusions of VM or banana pseudostem hay. No difference was observed for crude protein digestibility in the evaluated contrasts. When associated with virginiamycin, banana pseudostem hay provides satisfactory performance and nutritional parameters for feedlot sheep. Virginiamycin does not change the performance or nutritional parameters of these animals when Tifton grass hay is used as the only roughage sourc

Nutritional parameters and performance of crossbred heifers fed with millet and BRS 716 biomass sorghum silages

ABSTRACTThis study addressed the different proportions of millet and sorghum silage biomass BRS 716 (BRS-716 silage) in the diet of crossbred heifers ¾ Holstein x ¼ Zebu on their nutrient intake, and digestibility, microbial protein synthesis, nitrogen balance, ingestive behaviour, and growth performance. Five experimental diets with 0, 25/75, 50/50, 75/25, and 100% of BRS-716 silage in compared to millet silage were evaluated. The roughage: concentrate ratio in the total dry matter (DM) of the diets was 75:25. The diets were evaluated in ten heifers with an initial body weight of 264.95 ± 19.4 kg (± SEM), following the experimental design in two 5 × 5 Latin squares, simultaneously. The total experimental period lasted 105 d, divided into five periods of 21 days, including a 17-d initial adaptation, and four for data collection, and samples. The increase of BRS-716 silage in the diet of crossbred dairy heifers did not change the dry matter intake (DMI), and indigestible neutral detergent fiber (iNDFI). For the purine derivatives, and microbial synthesis, there was no significant effect (P > 0.05). The average daily gain was 0.795 kg/d. The millet silage, and BRS-716 silage in the diet of crossbred Holstein × Zebu heifers used exclusively or combined in different proportions
