The objective of this study was to evaluate the chemical composition and bone strength of the tibiotarsus of broilers at 7 and 14 days of age. Bone percentages of collagenous protein (CPr), non-collagenous protein (NCPr) and minerals (calcium, phosphorus, potassium and sodium) were determined. The experiment utilized 650 male Cobb chicks at one day of age, fed corn and soybean meal-based diets. The experimental design was of random blocks with five treatments, five replicates and 26 birds per experimental unit. The treatments consisted of a basal diet supplementated with NH4Cl to obtain five levels (-50, 0, 50, 100 and 150 mEq/kg) of electrolyte balance (EB). The levels of EB influenced the following characteristics: ash and potassium content; Ca:P ratio and the breaking strength (at 7 days); and phosphorus and potassium contents and breaking strength (at 14 days). At the starter phase of rearing, the supply of acidogenic diets affected the concentrations of potassium and phosphorus in the bone tissue, without altering the organic fraction.

O presente trabalho teve como objetivo determinar a prevalência de Salmonella sp. em suínos abatidos em frigoríficos sob Inspeção Federal no Estado de Mato Grosso. Amostras de linfonodos mesentéricos e tonsilas de diferentes procedências foram coletadas em três frigoríficos. Das 300 amostras processadas, 50 (16,6%) foram positivas para Salmonella sp., sendo identificados 14 diferentes sorovares. Os sorovares mais freqüentes foram Derby (16%), Typhimurium (14%), London (12%) e Give (12%). Os resultados epidemiológicos obtidos mostram uma baixa prevalência desta bactéria quando comparados com os resultados de estudos realizados em outros Estados.

The present study aims to determine the prevalence of Salmonella sp. in pigs in slaughterhouses under Federal Inspection at Mato Grosso, Brazil. Samples of mesenteric lymph nodes and tonsils were collected in three abattoirs from different regions. Three hundred samples were processed; fifty (16.6%) were positive for Salmonella sp. and belonged to fourteen different serological types. The most common serotypes were Derby (16%), Typhimurium (14%), London (12%) and Give (12%). The epidemiological results obtained show a low prevalence of this bacterium when compared to studies in other Brazilian states.

Foram avaliados os questionários respondidos por 476 alunos, com idade entre 15 e 20 anos, de uma escola do bairro Pedra 90 em Cuiabá-MT, objetivando conhecer as características da população canina e felina daquele local. Dos 476 domicílios, em 371 (78%), foram registrados 513 cães e 307 gatos. Dos 513 cães, 289 (56,3%) eram machos e 224 (43,7%) fêmeas. Dos 307 gatos, 182 (59,3%) eram machos e 125 (40,7%) fêmeas. Os proprietários de 474 (92,4%) cães e 267 (86,9%) gatos afirmaram ter vacinado seus animais contra raiva.

Questionnaires answered by 476 students (age 15-20 yrs) attending a local school in the neighborhood of Pedra 90 in Cuiabá-MT were analyzed in order to study the characteristics of feline and canine populations in the region. The results showed that 371 (78%) of the 476 families kept 513 dogs and 307 cats. Of 573 dogs, 289 (56.3%) were male and 224 (43.7%) were female. Of 307 cats, 182 (59.28%) were male and 125 (40.72%) were female. The owners of 474 (92.4%) dogs and 267 (86.9%) cats reported that their pets had been vaccinated against rabies.
