| In developing countries across the globe the impact of livestock on deforestation levels has been profound. This paper explores the role of the cattle industry in household decision making for small landholders in the Brazilian Amazon. Important inquiries raised in the literature are addressed, including the determinants of the co-evolution of deforestation and cattle herds, the possibility of production specialization, and the role of cattle in household livelihoods. Panel data suggest that households have changed focus from crop introduction to cattle. Empirical models reveal that location, wealth, and education are among the important determinants of production decisions and cattle accumulation. Policy recommendations include a focus on the cattle... |

| ABSTRACT: Caudal vena cava thrombosis (CVCT) is an acute disease secondary to ruminal lactic acidosis and rumenitis with fatal outcome in cattle fed with a high-grain diet. The aim of this paper is to describe CVCT in an adult Holstein cow from a herd in Balcarce, Buenos Aires, Argentina. Clinical signs included dyspnea, weakness, recumbence, and hemoptysis, followed by death in 3.5 days. Important necropsy findings included multiple hepatic abscesses, a septic thrombus (4.0cm x 2.0cm) in the vena cava adjacent to the liver, and a 15cm hematoma in the right lung. Histological lesions observed in the pulmonary parenchyma included suppurative pneumonia with embolic bacterial colonies and severe interstitial fibroplasia. Dissociation and degeneration of... |

| The aim of the present study was to investigate the changing profiles of plasma metabolic hormones during the ovarian cycles of beef and dairy cattle. We used 16 non-pregnant, non-lactating Japanese Black beef cattle (6 heifers and 10 cows; parity=2.3 ± 0.8) and 12 multiparous Holstein dairy cows (parity=3.0 ± 0.3). Blood samples for hormonal analysis (growth hormone, GH; insulin-like growth factor-I, IGF-1; insulin; and progesterone, P4) were obtained twice weekly for 40 days before artificial insemination for Japanese Black cattle and from 50 to 100 days postpartum for Holstein cows. Luteal phases were considered normal if the P4 concentrations for at least 3 time points over the course of 7 days remained above 1 ng/ml and at least 2 of the time points... |

| Abstract Klebsiella pneumoniae is important human and animal pathogen that causes a wide spectrum of infections. In this study, isolates from cattle nasal swabs samples were identified by 16S rRNA, and to evaluate the antimicrobial susceptibility, virulence gene carrying levels, and multilocus sequence typing of K. pneumoniae isolates. 33 isolates of K. pneumoniae were isolated and identified in 213 nasal swabs samples, of which 12 were hypervirulent K. pneumoniae strains. Extended Spectrum Beta-Lactamases genes were found in 93.4% of the strains. Of which, TEM was the most prevalent (93.4%), followed by CTX-M and SHV were 57.6% and 39.4%, respectively. A main mutation pattern of quinoloneresistance-determining region, Thr83-Ieu and Asp87-Asn in gyrA and... |

| ABSTRACT Chromobacterium violaceum is a rare opportunistic pathogen that causes highly fatal infections in domestic animals and humans. This report describes a fatal case suggestive of septicemia in a four-day-old female calf with chromobacteriosis. The calf had suppurative omphalophlebitis, suppurative fibrinous polyarthritis, anterior uveitis with bilateral fibrin deposition, fibrinous peritonitis, lymph node abscess and multifocal lymphocytic and neutrophilic encephalitis with multifocal hemorrhages. C. violaceum was isolated from the spleen and peri-renal lymph node and its identity was confirmed by PCR and sequencing. The pathogen was sensitive to azithromycin, gentamicin, enrofloxacin, norfloxacin, marbofloxacin, ciprofloxacin, erythromycin,... |

| ABSTRACT Osteoarthritis and osteochondrosis are highly correlated to reproductive failure in bulls. This study aimed to evaluate the carpal, tarsal and interphalangeal lesions in beef zebu bulls on semen collection regimen. Twenty-one beef cattle bulls, in a total of forty-one animals, were split into three age-based groups: animals from two to four years old (GI), from more than four to eight years old (GII) and above eight years old (GIII). The clinical findings were conformational changes of limbs, synovial effusion, peripheral venous engorgement of joints and prolonged decubitus. The total population showed moderate clinical manifestation and radiographic score. The GIII presented more severe joint lesions. Carpi and tarsi regions had discrete to... |

| Trypanosoma evansi from buffalo, cattle and horse isolates were purified by Diethylaminoethyl cellulose column chromatography. The purified trypanosomes from each sources were used separately for preparation of whole cell lysate antigens. A comparative study on polypeptide pattern of whole cell lysate antigens of these three isolates of T. evansi was studied. It showed a total of 11 dominant polypeptide bands with relative molecular weight ranging from 95 to 13 kDa, when resolved in 10% sodium dodecyl sulphate polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue. Except some minor differences between the relative molecular weight of isolates in a particular region, the polypeptide profiles of these three isolates did not resolve any... |

| El objetivo fue evaluar el comportamiento y fisiología de ganado bovino de doble propósito pastando sitios con cobertura arbórea alta (CAA), baja (CAB) y sin cobertura (SCA), en las épocas de lluvia y sequía. Se observaron vacas adultas durante 24 días en cada época, registrando la temperatura corporal y los tiempos que dedicaron a las distintas actividades durante el día. Las vacas dedicaron el mismo tiempo al consumo en las lluvias (P > 0.05), sin embargo, hubo mayor tiempo en CAB durante la sequía (P < 0.0001). Durante las lluvias, las vacas en pastoreo bajo CAA mostraron menor motivación de irse al descanso o iniciar la rumia (P<0.001), y mayor hacia la exploración que en otros tratamientos (P<0.001); durante la sequía, aquellas pastando en... |

| El objetivo fue evaluar la composición química y calidad de la carne de bovinos en diferentes sistemas de alimentación del estado de Puebla, México. Se realizó un muestreo en cuatro regiones: Trópico Este y Trópico Oeste donde la alimentación es en pastoreo más alimento concentrado y en el Centro y Mixteca, donde el sistema es estabulado con alimento concentrado. En cada región se definieron tres sitios y en cada uno se muestrearon 3 animales (n=36). Se evaluó el músculo Longissimus dorsi para determinar humedad, proteína, extracto etéreo (EE), cenizas, ácidos grasos, pH, color (L*a*b), capacidad de retención de agua (CRA), pérdida de agua por cocción (PPC), textura, y se colectó una muestra de sangre para determinar clenbuterol. En humedad, proteína y... |
