Boerka goat is the best meat type goat. Feed quality is one of the biggest factors that affect productivity, so it is necessary to know in advance the need for nutrients. The purpose of this study was to determine the dietray of crude protein (CP) and Total Digestible Nutrients (TDN) in efficient feed for the production of Boerka goats male growing phase. This study was designed in a completely randomized design, consisting of six combination feed treatments with six replications. Namely: 1 (CP 13.00% and TDN 63.10%); 2 (CP 13.03% and TDN 65.07%); 3 (CP 13.00% and TDN 70.00%); 4 (CP 15.00% and TDN 62.69%); 5 (CP 15.12% and TDN 65.00%); 6 (CP 15.00% and TDN 70.00%). The observed variables were feed consumption, feed consumption ratio (FCR), nutrient digestibility (dry matter, organic matter, crude protein) and average daily gain (ADG). Results of this study show that the balanced of CP and TDN has no significant effect on consumption and FCR. However, it was significantly different for digestibility and ADG. Feed treatment (CP 13.03% and TDN 65.07%) obtained the higher digestibility of DM and OM (71.49 and 70.5%), while the highest CP digestibility was treated with CP 15.05% and TDN 62.69% (71.59%). The ADG response of Boerka goats with CP 13.03% and TDN 65.07% was the good results (144.90 g head-1day-1) while the lowest response was on CP 13.08% and TDN 63.10%. It is concluded that the dietray of CP 13.03% and TDN 65.07% is a recommended of Boerka goat male growing phase.

Many complicated bone fractures can be healed by different techniques including linear external fixation. New generation linear external fixators enhanced the scope of application for bone fractures by mechanical progress. Difficulties include implementing enough pins through fixation clamps to the comminuted fragments or clamp addition and fixing it properly to the rod with the correct pin insertion angle. Effective configurations may not always result. This study sought to reveal the clinical efficiency of modified clamps of a versatile external fixator (VEF) to fix different types of fractures and orthopedic problems according to the radiographic and clinical results. We used this fixator on 17 cats and 17 dogs of different ages and sizes, having different types of antebrachium, humerus, tibia, ulna fractures, and bone-muscle deformities. Clamps had different features to connect fixator pins. Many fixator configurations were created according to the fracture type and body weight of the animals. The most used ones were unilateral and bilateral configurations. The callus formation and visual gait analysis were observed after the operations, until the removal of the fixator. After fixator removal, the visual gait status of the limbs was excellent in 67% of the cases, good in 15%, fair in 12%, and poor in 6%. We found that rods and fixator pins were connected easily by semi-locked clamps. Also, the double pin holding clamps saved space on the fixation rod by the application of two pins through one clamp. We think that clamps of versatile external fixators can easily be constructed to limb fractures and save time during surgery.

Bovine mastitis is the most important disease of dairy herds worldwide. Its main etiologic agents are bacteria, including Streptococcus agalactiae. The importance of this agent in bovine mastitis is because it is highly contagious and has a high impact on the occurrence of clinical mastitis cases and in the increase of the bulk milk somatic cell counts. The dry cow therapy and the treatment of the clinical mastitis cases stand out among the measures to control intramammary infections in cows. However, these strategies require knowledge about the antimicrobial susceptibility of the causal microorganisms. Thus, this study aimed to evaluate the antimicrobial susceptibility of 89 S. agalactiae strains isolated from bovine mastitis between the years 2004 and 2008 in dairy herds from Campo das Vertentes region, Minas Gerais State, Brazil. The disc diffusion technique was used and the antimicrobials currently used in mastitis therapy were tested. The isolates tested showed 100% susceptibility to chloramphenicol, ceftiofur, cefotaxime, enrofloxacin, and cefquinome. High frequencies of susceptibility (>95%) were also observed for the beta-lactams (penicillin G, ampicillin, and oxacillin), cephalosporins (cephalotin, ceftiofur, cefotaxime, cefoperazone, and cefquinome), florfenicol, gentamicin, lincomycin, nitrofurantoin, and sulfamethoprim. The strains showed high frequencies of resistance to neomycin (15.74%), and tetracycline (21.35%). Multidrug resistance was detected in 2.25% of the tested isolates. The results pointed to variations in the antimicrobial susceptibility profiles of the studied strains and the importance of the use of the susceptibility tests to determine the correct antimicrobial to be applied in the treatment of bovine mastitis caused by S. agalactiae. The high frequencies of resistance observed to some antimicrobials, such as neomycin and tetracycline, commonly used in the treatment of mastitis and other pathologies, highlighted the need for more judicious use of antimicrobials on dairy farms.

Over the past two decades, many Brazilian cities have been reporting an increasing incidence and spread of feline sporotrichosis. The disease is neglected, and little is known about the causal processes underlying its epidemic occurrence. This study characterized the spatiotemporal dynamics of feline sporotrichosis in Guarulhos. Moreover, we proposed and tested a causal explanation for its occurrence and zoonotic transmission, giving a key role to social vulnerability. A direct acyclic graph represented the causal explanation, while Bayesian spatial models supported its test as well as the attribution of a risk-based priority index to the census tracts of the city. Between 2011 and 2017, the disease grew exponentially and the spatial spread increased. The model findings showed a dose-response pattern between an index of social vulnerability and the incidence of feline sporotrichosis. This pattern was not strictly monotonic, so some census tracts received a higher priority index than others with higher vulnerability. According to our causal explanation, there will not be effective prevention of feline and zoonotic sporotrichosis as long as social inequities continue imposing precarious livelihoods.

Currently, the use of alternative medicine is necessary, even in animals. Our study focused on the valorisation of the use of herbal products in Algerian veterinary medicine. This study is based on a 6-month exploratory survey of 257 private practicing veterinarians, followed by a study of the bacteriological activity of the essential oil of the Pistacia lentiscus plant. The survey results generally  indicate that private veterinarians support phytotherapy as an alternative to conventional drugs in several areas and species. Also, the results of research conducted on the antibacterial activity of Pistacia lentiscus essential oil show that it inactivates 50% of the bacterial strains. This confirms the well defined role of this medicinal plant used as an alternative in veterinary medicine.

Enteroliths are concretions of minerals that cause partial or total obstruction of the intestinal lumen, resulting in recurrent and chronic colic in horses. This pilot study aimed to evaluate the in vitro solvent effect of carbonated beverages (CocaCola® and Coca-Cola® Zero), and papain and cellulase enzymes (Robinson Pharma®, Santa Ana, CA, USA) on enteroliths obtained from horses. Six 51-grams samples of six enteroliths were assigned to six treatments of immersion solutions: T1, Coca-Cola®; T2: Coca-Cola® Zero; T3: distilled water + papain (90 mg) and cellulase (120 mg); T4: Coca-Cola® + papain and cellulase; T5: Coca-Cola® Zero + papain and cellulase; and, CT: distilled water (control). The volume for immersion in the assigned solution was 150 mL, at a pH of 7.1, using an incubation shaker (Heidolph® , Germany) at 37ºC and 25 rpm, for 72 h. The evaluation periods of the dissolution percentage (difference between the initial weight and final weight of the samples), were 0, 3, 12, 24, 36, 48, 60, and 72 h. After 72 h of immersion, solutions T4, T5, and T1 presented 47, 38.8, and 14.9% of dissolution, respectively. The other solutions did not have major differences with CT (control). Under the in vitro conditions of this pilot study, papain and cellulase enzymes potentiated the dissolving effect of the carbonated solutions on the enteroliths obtained from horses. Further studies are suggested since the existing literature is on the dissolution of phytobezoars and not of enteroliths.

The seroprevalence of Leptospira spp. and infection risk factors were investigated in horses from a military contingent in the Rio Grande do Sul State, Brazil. A total of 446 horses were evaluated and categorized into 309 mares, 11 stallions, and 126 horses with an average age of three years. To determine seroprevalence, serum samples from all horses were submitted to the microscopic agglutination test against 12 serovars belonging to nine serogroups, usually circulating in equine populations. To investigate the possible risk factors of infection by Leptospira spp., questionnaires were applied in that military unit. The seroprevalence in the horses with an average age of 3 years, mares, and stallions were 57.94% (73/126), 54.05% (165/309), and 45.45% (5/11), respectively. The main risk factors identified were contact with different water sources, the presence of rodents, and contact with wild and domestic animals. The high seroprevalence of anti‑Leptospira spp. antibodies may be associated with the presence of these risk factors. Therefore, the exposure of horses to possible reservoirs of Leptospira spp. should be minimized. Also, the immunoprophylaxis protocol should be reviewed and a shorter interval between vaccinations adopted to control leptospirosis in this herd.

This study aimed to evaluate the role of prostaglandin F2α (PGF) on ovulation. In Experiment 1, cows were randomly allocated to two treatments to receive 150 μg of d-Cloprostenol (PGF Group, n = 12) or 2 mL of NaCl 0.9% (Control Group, n = 11) and CIDRs, were removed 4 days later. No cow ovulated in Control and PGF groups. In Experiment 2, cows were randomly separated into two experimental groups to receive 4 injections of 150 μg of d-Cloprostenol (n = 9) or 2 mL of NaCL 0.9% (n = 9). In this experiment, ovulation was not observed in any cows. In Experiment 3, ovariectomized cows receive three injections of 300μg of PGF analog (PGF Group, n = 5), 100μg of Lecirelin (GnRH Group, n = 5) or 2 mL of PBS (Control Group, n = 4). The LH concentration was higher (P <0.0001) in cows from the GnRH group than in the PGF and Control groups. In experiment 4, cows with preovulatory follicles (>11.5 mm) were treated with Saline (Control Group, n = 6); Lecirelin (GnRH Group, n = 7) or Cloprostenol Sodium (PGF Group, n = 6). There was a significant increase in the vascular area of follicles from 0 to 24 h in GnRH and PGF treatments. In conclusion, PGF was not able to induce ovulation in cows with high or low plasma progesterone concentration. Additionally, PGF alone was not able to induce LH release and follicle luteinization, but increased follicular vascularization.

The epidemiological characteristics of bovine leptospirosis in animals and herds in Mato Grosso do Sul were investigated to determine parameters such as disease frequency and the serovars reactant in beef cattle herds. A total of 4,629 beef cattle herds were examined against 33 Leptospira spp. serovars. The serum samples were submitted to the microscopic agglutination test (MAT) for the serological diagnosis of leptospirosis. The MAT results showed that 3,814 (82.39%) of the 4,629 animals evaluated were seropositive for the bacterium, with serological reactions mainly to serogroup Sejroe, serovar Wolffi (36.49%). The observed high frequency of reactive animals demonstrates the relevance of the infection. Therefore, general and specific measures should be implemented to contain and/or prevent infection of the animals in the studied region.

O compósito à base de hidroxiapatita, quitosana e nanotubo de carbono foi desenvolvido com o intuito de auxiliar na consolidação óssea. Estudos anteriores sugerem que a combinação de substitutos ósseos e células-tronco mesenquimais (CTM) podem auxiliar a potencializar e promover a regeneração óssea. No presente estudo, o biomaterial foi desenvolvido e a viabilidade e a citotoxicidade de células Vero (ATCC CCL-81) e CTM obtidas de medula óssea provenientes de ovinos utilizando ensaios metil-tiazol-tetrazólio, MTT e iodeto de propídeo (PI) foram avaliadas em diferentes concentrações de extrato desse compósito. O compósito demonstrou ausência de citotoxicidade com comportamento semelhante ao grupo controle. Amostras com 50% e 10% de concentração de extrato do compósito mostraram resultados maiores comparados ao grupo controle (ensaio MTT). Esses resultados também sugerem que a presença do biomaterial pode ser utilizada em associação a CTM. Assim, esse estudo conclui que o compósito apresentado de hidroxiapatita, quitosana e nanotubo de cabono não foi considerado citotóxico e pode ser utilizado em teste in vivo.
