title: USE OF HYDROALCOHOLIC EXTRACT OF Schinus terebinthifolius Raddi IN PRE- AND POST-MILKING ANTISEPSIS OF THE TEAT IN DAIRY COWS

description: Abstract Medicinal plants have been used for centuries as an alternative treatment for health problems. Schinus terebinthifolius Raddi is a median tree that belongs to the Anacardiaceae family. The antibacterial effect of leaves extract of this plant has already been demonstrated. The objective of this study was to test a substance derived from this plant to be used in pre- and post-milking teat antisepsis. The hydroalcoholic extract of Brazilian pepper tree was used in opposite quarters for twelve consecutive weeks, and commercial iodine was used as control. None of the indices analyzed - black background mug, CMT, intramammary infections, skin health, and teat health - showed a statistical difference between the treatments, suggesting that the plant extract can be used in pre- and post-milking teat antisepsis, as a substitute for conventional products for herds in an agroecological production system.

title: ANESTHETICS EFFECTS OF INTRANASAL OR INTRAMUSCULAR ASSOCIATION OF MIDAZOLAM AND RACEMIC OR S+ KETAMINE IN BUDGERIGARS (Melopsittacus undulatus)

description: Abstract Intranasal anesthesia in birds is considered a safe, simple and efficient technique. The aim of this study was compare the anesthetic effects of midazolam (5 mg.kg-1) with racemic (R) or S+ (S) ketamine (15 mg.kg-1), administered intranasally (IN) or intramuscularly (IM) in budgerigars (Melopsittacus undulatus). Eight budgerigars were used in a crossover design with four treatments: INR, INS, IMR and IMS. Onset time, dorsal recumbency time duration, total anesthesia time, total recovery time, sedation degree and recovery quality were evaluated. Significant differences were observed in onset time between INS (40.25±10.55 sec) and IMR (74.32±21.77 sec); between administration vials for dorsal recumbency time, INS (23.93±7.51 min) and INR (28.68±16.13 min), which were different from IMS (60.08 ± 27.37 min) and IMR (74.3±21 min). In total anesthesia time, INS (45.48±17.94 min) and INR (39.24±15.62 min) were different from IMS (75.84±20.20 min) and IMR (20.73±79.4 min). The total recovery time was significantly higher in INS (21.55±18.43 min) compared to IMR (5.1±3.56 min). The results of this study indicated that both administration vials can be used for short time non-invasive procedures and the intranasal vial is preferable for fast procedures.

title: EFFECT OF MONENSIN SODIUM ON METABOLIC PROFILE OF EWES BEFORE AND POSPARTUM

description: Abstract The study was carried out to analyze the effect of monensin supplementation during 60 days prior to parturition, and 30 days postpartum, on the metabolic and hormonal profile of ewes. Pregnant ewes (n=13) were randomly divided into two groups: monensin group (n = 7; 30 mg/day) and control group (n = 6). Blood and ruminal fluid samples were collected 60, 50, 40, 30, 20 and 10 days prior to parturition, at the time of parturition and on 10, 20 and 30 days postpartum. The following variables were analyzed: glucose, fructosamine, non-esterfied fatty acids, β-hydroxybutyrate, cholesterol, triglycerides, total protein, albumin, urea and ketone bodies in the urine. The hormonal determinations were cortisol and insulin. The analysis of the ruminal fluid involved pH and concentration of volatile fatty acids. The statistical analysis involved ANOVA and correlation studies (P&lt;0,05). Monensin increased (P&lt;0,05) the propionic acid concentration in the rumen and blood fructosamine and insulin. The administration of monensin improved some indicators of energy balance.

title: TONOMETRY OF THE FEMORAL ARTERY IN HEALTHY DOGS AND IN THOSE WITH CHRONIC DEGENERATIVE MITRAL VALVE DISEASE

description: Abstract Applanation tonometry is a method capable of measuring blood pressure in an artery. In addition to speculation about the reason for the variations in amplitude of femoral pulse waves in dogs with chronic degenerative mitral valve disease (CDMVD), in medicine, it has been demonstrated that many symptoms of heart failure in people are attributable to peripheral vascular functional abnormalities, and they are not highly associated with central hemodynamic parameters. Thus, this study aimed to verify the applicability of the vascular tonometry in dogs, to evaluate the pressure measures of the femoral artery in healthy dogs, and compare them with those of dogs with mitral regurgitation due to CDMVD. Moreover, the parameters established for tonometry were correlated with cardiac index obtained by echocardiography. For this, the data were obtained from 10 healthy dogs and 10 dogs with CDMVD with mitral regurgitation on echocardiography. We observed that the pre-conduction period of the femoral pulse wave was significantly lower in CDMVD than in healthy animals. There was a strong correlation between systolic pressure of the femoral artery with determining parameters of cardiac systolic function in healthy animals. The applanation tonometry of the femoral artery was an applicable technique in dogs.

title: BIOLOGICAL ASPECTS OF RODENT Holochilus sp., NATURAL HOST OF SCHISTOSOMIASIS

description: Abstract In the present study, we aimed to analyze the reproductive aspects (seasonal period and number of embryos) and positivity for S. mansoni in rodent of Holochilus gender, in São Bento - MA. For this, monthly captures of up to 10 Holochilus sp. rodents were conducted, randomly for sex, taking notes of the seasonal period of São Bento in each month of capture. At the laboratory, rodents had feces analyzed for S. mansoni infection by Kato-Katz method. After the analysis, they were adequately anesthetized for obtaining full length, weight and sex determination. In females, an incision of the ventral portion of the body was carried out to verify the presence of embryos and to count them. Among the captured rodents, there was male dominance in almost all months and they tended to be heavier and had larger bodies than the females. The animals showed high reproductive potential. The positivity for S. mansoni and the reproduction of Holochilus sp. were greater in the rainy season of São Bento. As for the number of embryos, we observed that, in the rainy season, more males were found than female. In short, the intense reproductive activity, along the susceptibility to S. mansoni presented by rodents are factors that help to maintain and aggravate schistosomiasis in Baixada Maranhense.

title: NUTRITIVE VALUE OF A NATIVE PASTURE DOMINATED BY Eragrostis plana Nees AND ITS RELATION WITH METABOLIC PROFILE OF PRIMIPAROUS COWS SUPPLEMENTED FROM PREGNANCY TO POSTPARTUM

description: Abstract The objective of this research was to evaluate the quality of the forage mass of a native pasture covered by 70% of Eragrostis plana Nees (South African lovegrass) under continuous grazing of primiparous cows. The following chemical characteristics of forage components leaves and stems of South African lovegrass and native species were evaluated: organic matter in vitro digestibility (OMIVD), crude protein (CP), and neutral detergent fiber (NDF). The protein and mineral metabolic profile in blood was associated with the supplements common salt, mineral salt, protein salt and reproduction salt. There was higher crude protein content in leaves and stems of South African lovegrass in winter (9.4% and 6.7) and spring (8.9% and 6.6), respectively. Metabolic protein in the blood did not differ among supplements (P&gt; 0.05), but levels of albumin (34.5 to 25.3 g/L) and urea (36.2 to 30.1 mg/dL) decreased from winter to summer. There was deficiency of the average content of mineral phosphorus for cows supplemented with protein salt (3.9), mineral salt (3.3) and common salt (2.2) in spring and common salt (2.9 mg/ dL) in summer. Primiparous cows managed on native pasture with a prevalence of 70% coverage of South African lovegrass need mineral phosphorus supplementation with reproduction salt in spring and summer.

title: SUBSTITUTION OF STARCH SOURCES BY SOLUBLE NEUTRAL DETERGENT FIBER IN DAIRY COWS DIET

description: Abstract The objective of this research was to evaluate the effects of replacing corn grain by citrus pulp on dairy cows performance. Nine Holstein cows (three cannulated in the rumen), at 80 ± 24 milking days, and daily medium production of 20 ± 0.58 kg/day were used. Animals were maintained in tie stall with individual feeder and drinker. Experimental design was a 3 x 3 Latin square. Experiment lasted 21 days, being 14 days of adaptation and seven of collection. Treatments were 100% corn grain (CG); 50% corn grain and 50% citric pulp (CG-P) or 100% citrus pulp (P). There were no differences in nutrients (DM, OM, NDF, ADF, CP, starch) ingestion among diets. The treatment with citrus pulp produced larger proportion of acetate in relation to the others, as well as larger acetate/propionate ratio. The pH averages ranged between 5.86 and 7.35. The averages of N-NH3 presented larger differences in the times 2 and 3 hours after feeding. There were no differences among the diets for total 4%-fat corrected milk production, protein, lactose, total dry extract (TDE) and milk urea nitrogen (MUN).

title: NUTRITIVE VALUE OF SILAGE OF PIATÃ GRASS MONOCROP AND INTERCROPING WITH SORGHUM FOR FORAGE AND GRAZING

description: Abstract The objective of this study was to evaluate the influence of the time of cutting on the nutritive value of Piatã silage grass in monocrop and intercropping with sorghum for cutting and grazing. We used a randomized block design with four replications. Treatments were arranged in a split plot design, with systems as plots (Piata grass, sorghum for cutting and grazing, and intercropping), cutting ages as sublots (70, 90, and 110 days after sowing). The minisilos were opened at 46 days to evaluate silage crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN), ammonia nitrogen, lignin, and pH. We observed significant interaction between system and age on the variables CP, ADF, NDF, lignin and pH. With the advancement of age, there was a linear reduction in crude protein content of 0.12, 0.08, and 0.16 percentage units for each day after sowing in sorghum silage, sorghum grass and grass + Piata, respectively. There was a linear increase in the pH value of sorghum silage + grass due to the advancement of age of 0.03 units for each day after sowing. In sorghum silage and monocrop grass, the pH did not vary with the cutting age, with values of 4.63 and 5.20, respectively. Sorghum systems showed potential for the production of good quality silage at 70 days of age.

title: GROWTH DYNAMIC AND FORAGE YIELD OF Trachypogon plumosus UNDER LEVELS OF SOIL FERTILITY CORRECTION AND REGROWTH AGES

description: Abstract We assessed the effects of levels of soil fertility correction (control, liming, fertilization and liming + fertilization) and of regrowth ages (21, 28, 35, 42, 49, 56, 63, 70, 77, and 84 days) on growth dynamic and forage yield of Trachypogon plumosus in the Roraima´s savannas. Dry matter (DM) yields, absolute growth rate (AGR), net assimilation rate (NAR), and leaf area ratio (LAR) increased consistently with regrowth age, while the crop growth rate (CGR) was inversely proportional to regrowth age. The grass showed high responsivity to soil fertility improvement. Liming + fertilization or fertilization alone provided higher DM yields (1,934 and 1,661 kg ha-1), AGR (36.6 and 31.5 kg ha-1.day), CGR (32.5 and 27.9 kg ha-1.day), NAR (4.993 e 4.152 g/m2), LAR (152.9 and 140.9 cm2/g), and LAI (2.42 and 2.14). Regrowth intervals of 56 to 63 days for liming + fertilized and fertilized pastures, and 63 to 70 days for control or liming pastures were appropriate to provide maximum forage yields, growth rates and to prevent larger losses relative to senescence and leaf death.
