RESUMO

Anecdotal reports suggest that the new coronavirus SARS-CoV-2 pandemic (COVID-19) has increased overweight and obesity prevalence in dogs and cats. The present report aimed to perform a retrospective overweight/obesity survey on 1,001 consecutive cases attended in the Veterinary Clinics Hospital from the Federal University of Rio Grande do Sul during its reopening to the public after months closed due to the pandemic. The overall overweight or obesity observed prevalence was 36.63%; being the frequency in cats slightly greater (38.37%) than compared to dogs (35.76%). No local increase in these frequencies was detected. Neutering (dogs and cats), age greater than 10 years (dogs), and male gender (cats) were factors associated with overweight/obesity. Bodyweight was not registered in about 30% of the medical records, while the body condition score was not registered in about 50% of the cases. These flaws were more often observed in feline medical records and efforts to improve these data records are warranted.

Especula-se que a pandemia pelo novo coronavirus SARS-CoV-2 (COVID-19) tenha agravado a prevalência de sobrepeso e obesidade em cães e gatos. O presente artigo teve como objetivo realizar um levantamento de sobrepeso/obesidade, o qual avaliou os registros de 1001 casos consecutivos atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul, durante a reabertura da instituição ao público, após meses fechada devido à pandemia. Observou-se uma prevalência de sobrepeso ou de obesidade de 36,63%, sendo a frequência ligeiramente maior em gatos (38,37%) do que em cães (35,76%) e não sendo documentado aumento local na prevalência. Castrações (cães e gatos), idade > 10 anos (cães) e sexo masculino (gatos) foram associadas ao sobrepeso/obesidade. Em cerca de 30% das fichas não havia peso registrado, e em cerca de 50% não havia registro de ECC. Essas falhas foram mais frequentes em fichas de felinos e demandam medidas para aumentar o registro desses dados pelas equipes clínicas.

RESUMO

The physically effective neutral detergent fiber content alone has not been able to explain the appearance of diarrhea in ruminants fed diets with large volumes of spineless cactus, so the proliferation of enterobacteria in spineless cactus may be associated with cases of diarrhea in sheep. In the in vitro test, used two varieties of spineless cactus, both of which were chopped to particles of 4 and 2 cm2. For the in vivo test, 15 lambs were allocated to three treatment groups, namely, spineless cactus crushed and immediately supplied to the animals; spineless cactus crushed 8 h before supply; and silage of spineless cactus. The variables evaluated were dry matter intake, weight gain, fecal score, hemogram, and fecal colony count. In the in vitro test, higher Enterobacteriaceae and lactic acid bacteria counts were found both at 12 h and 24 h when the spineless cactus was crushed to 2 cm2 in both varieties. The sheep fed the spineless cactus crushed 8 h prior to supply showed the highest Enterobacteriaceae count in the feces (8.48 CFU/g), compared to animals fed silage of spineless cactus (4.95 CFU/g). It can thus be concluded that the management of spineless cactus influences the development of total and fecal coliforms, especially when it is chopped to 2 cm2 and exposed to the environment for periods longer than 7 h, and that the bacterial population can be controlled by administering the spineless cactus in the form of silage.

RESUMO

Background: Cats can be defined as being overweight if their bodyweight is 15% above optimum weight and classified as obese if they are more than 30% above their optimum weight. There is a general agreement among investigators that the incidence of excess body weight in cats is increasing. Obesity has considerable impacts on the health of cats and is linked to a variety of health issues including orthopedic disease, diabetes mellitus and non-allergic skin conditions. The purpose of the present study was to evaluate the relationship between obesity and associated diseases in cats examined at some veterinary practices in Istanbul-Turkey. Materials, Methods & Results: Data of 2,272 patients examined at four private veterinary practicesin Istanbul was studied to reveal the association between body weight and diseases. Information regarding sex, age and neutering status was also considered for each patient. Patients were classified according to their body weight to three groups as lightweight (female: 3.0 kg and under, male: 4.5 kg and under), optimum -weight (female: 3.0-4.5 kg, male: 4.5-5.5 kg) and overweight/obese (female: 4.5 kg and over, male: 5.5 kg and over). Accounting all adult cats treated by the clinics, diagnoses of osteoarthritis, heart diseases, dermatological diseases, hepatic lipidosis, metabolic syndrome - diabetes mellitus, lameness, gastrointestinal diseases, musculoskeletal diseases, neoplasia and urinary diseases were statistically evaluated. Considering data coming from 2,272 cats, which were referred to veterinary practices, 33.12%, were classified as overweight-obese, 40.04% were optimum-weight and 26.84% were lightweight. It was determined that overweight-obese cats were more likely to be diagnosed with osteoarthritis and hepatic lipidosis compared to other groups (P < 0.05). Overweight-obese cats were more likely to be diagnosed with gastrointestinal disease and neoplasia compared to lightweight cats (P < 0.05).[...]

RESUMO

A obesidade é a doença nutricional mais frequente em cães, leva a uma série de alterações nas funções corporais e limita a longevidade dos animais. Vários fatores contribuem para o desenvolvimento da obesidade em cães, como genética, raça, idade, falta de atividade física, composição calórica dos alimentos, tipo e a forma de alimentação, distúrbios hormonais, medicamentos e fatores relacionados com os proprietários. Devido à falta de estudos sobre os aspectos nutricionais e ambientais envolvidos no desenvolvimento da obesidade canina, o presente trabalho objetivou obter estas informações por meio de enquetes a proprietários. Foram realizadas 254 entrevistas com proprietários de cães com sobrepeso ou obesos, atendidos em Hospitais Veterinários Universitários. Selecionaram-se cães com escore de condição corporal (ECC) de 6 a 9, de acordo com escala descrita por LAFLAMME (1997). A maioria dos cães acometidos eram fêmeas adultas castradas, sem raça definida (33%) ou Poodles (17%). De acordo com 36% dos respondentes, o excesso de alimento era a possível razão do ganho de peso dos animais. Apenas 52% dos proprietários tentaram realizar controle de peso do seu animal, principalmente reduzindo a quantidade de alimento. Não houve correlação entre a condição corporal do proprietário, nível de escolaridade, renda familiar e ambiente domiciliar dos proprietários com o ECC dos animais. As informações obtidas podem auxiliar na identificação dos fatores nutricionais e ambientais envolvidos no desenvolvimento da obesidade em cães, podendo adotar medidas preventivas e desenvolver melhores estratégias para o tratamento.(AU)

Obesity is the most common nutritional disease in dogs and may cause many changes in body systems and limit the longevity of the animals. Many factors contribute to the development of obesity in dogs, as genetics, breed, age, lack of physical activity, caloric food composition, type and form of nutrition, hormonal disorders, medicine, and factors related to the owners. Due to the lack of studies on the nutritional and environmental aspects involved in the development of canine obesity, the present study aimed to obtain information through owners surveys. Interviews with 254 owners of overweight or obese dogs were conducted at University Veterinary Hospitals. Dogs were selected through body condition score (BCS) from 6 to 9, according to the scale described by LAFLAMME (1997). The data were coded, tabulated and submitted to frequency analysis and correlation (Spearman Test). Most affected dogs were castrated adult female of mixed breeds (33%) or poodles (17%). For most respondents (36%), food excess was the possible reason for the weight gain of pets. Only half of the owners have tried to achieve weight control of their pet, especially reducing the amount of food. There was no correlation between body condition of the owner, educational level, family income and home environment of the owners with pets BCS. Information obtained may help identifying nutritional and environmental factors involved in the development of obesity in dogs and can provide better preventive measures and strategies for treatment.(AU)

RESUMO

The impact of Cystoisospora felis infection on the nutritional efficiency of gerbils was studied. The variables weight gain and feed intake were measured during four weeks in 28 laboratory gerbils, of which 14 were inoculated with 3.5 × 10(5) sporulated oocysts of C. felis and the remaining 14 were controls. The animals from both groups were weighted, killed, eviscerated and had their carcasses and tissues weighted and compared. A modern tool designed for measuring nutritional performance of farm animals was applied. The results showed compromised nutritional efficiency of the infected animals within the first week after infection. The consequences of these results are discussed here, including the potential impact of infection on farm animals performance.

RESUMO

Vitamin D participates in mineral homeostasis, immunomodulation, cell growth and differentiation. The leaves of Solanum glaucophyllum contain high levels of 1,25-dihydroxyvitamin D3 as glycoside derivatives and their chronic ingestion generates a hypervitaminosis D-like state. We analyzed changes on carbohydrate expression as a cell differentiation indicator on samples of the small and large intestine of S. glaucophyllum-intoxicated rabbits, using conventional and lectin histochemistry. Male New Zealand white rabbits were intoxicated with S. glaucophyllum during two or four weeks and killed the day after. A group of animals ("possibly recovered group") were intoxicated during 15 days and killed at day 45 of the beginning of the experiment. We found changes in the lectin binding pattern in the small and large intestine of the intoxicated rabbits. Some of these changes were reverted in the possibly recovered group. Vitamin D could be a new regulator factor of the intestinal glycosylation process.

RESUMO

A carência de proteínas, causando Kwashiorkor, é o tipo de má-nutrição mais prevalente, pois fontes de alimentos protéicos, geralmente, são mais onerosas. Para estudos experimentais, o rato tem sido o principal modelo para avaliar as conseqüências de ingestão de dietas com diferentes teores protéicos, contudo ainda não estão claros os níveis de severidade dessas dietas para essa espécie. Nesse sentido, propõe-se avaliar a severidade de uma dieta hipoprotéica a 4% para ratos jovens. Para tanto, utilizaram-se 30 ratos Wistar (90 dias de idade), os quais foram divididos em dois grupos: controle (GC) e experimental (GC). O GC recebeu dieta normoprotéica, enquanto o GE recebeu dieta com 4% de teor de proteínas, ambos, durante 12 semanas. No final do experimento, avaliaram-se o peso, o crescimento, a massa gorda e massa magra dos animais. Os animais do GE não ganharam peso, tiveram retardo no crescimento, formaram menos massa gorda e menos massa muscular.(AU)

The protein lack causing Kwashiorkor is the most prevalent kind of malnutrition, because the food sources of proteins are usually more expensive. For experimental investigations, the rat has provided the primary model to evaluate the consequences of the ingestion of diets with different protein levels; however, the degrees of severity of these diets for these species are still not clear. In this sense, we aimed at evaluating the severity of a 4%-hypoproteic diet on young rats. We used 30 Wistar rats (90 days old), which were divided in two groups: control (CG) and experimental (EG). CG rats were fed with normoprotein chow, while EG rats were fed with a chow having 4% protein, for 12 weeks. At the end of the experiment, we evaluated the weight, growth, and fat and lean masses of the animals. The rats from EG did not gain weight, they had growth retardation, and built less fat and muscle masses.(AU)
