This study aimed to establish the optimal concentration of purified Kraft lignin (PKL) in the diet of finishing lambs. The experiment was arranged in a randomized block design, with four diets and LKR concentrations of 0, 6, 12, and 18 g/kg DM, with eight Poll Dorset × Texel crossbred lambs per treatment. The experiment was conducted with newly weaned lambs, aged 60 ± 10 days, with an average initial body weight of 23 ± 5 kg. The animals were [...] ABSTRACT This study aimed to establish the optimal concentration of purified Kraft lignin (PKL) in the diet of finishing lambs.

Sabe-se que a ultrassonografia é uma ferramenta diagnóstica acessível e economicamente viável, sendo considerada de eleição para a avaliação hepática. Pretendeu-se com este estudo avaliar qualitativamente (ultrassonografia modo B) e quantitativamente (histogramas em escala de cinza) o fígado de 28 cadelas em diferentes escores de condição corporal (ECC) quanto à presença de infiltração gordurosa; e a veia hepática direita (VHD) (modo B e modo Doppler colorido) quanto à sua visibilidade e presença de fluxo sanguíneo, respectivamente. A hipótese do presente estudo foi que a perda de peso reduziria a gordura hepática e, consequentemente, cessaria seu efeito mecânico sobre o lúmen venoso. Com isso, dividiu-se os cães do estudo em três grupos, de acordo com seu ECC: controle (ECC 4 ou 5), sobrepeso (ECC 6 ou 7) e obeso (ECC 8 ou 9), sendo este submetido à dieta, acompanhamento ultrassonográfico hepático e mensuração seriada de fosfatase alcalina (FA) e alanina aminotransferase (ALT). A dieta foi eficaz para o emagrecimento dos cães, porém a perda de peso não demonstrou efeitos sobre a VHD ou enzimas hepáticas. A utilização de histogramas auxiliou na detecção da gordura hepática e de sua redução ao longo da perda de peso do animal. Sendo assim, esta pode ser considerada uma ferramenta útil e de fácil execução, contribuindo no diagnóstico precoce e monitoramento da esteatose de forma não invasiva.

This study aimed to assess the health status of shelter dogs in two cities in the interior of São Paulo State, Brazil, as part of a university extension initiative focused on collective and preventive veterinary care. The project was conducted in two editions. The first was held in 2013 in a shelter in the city of Pirassununga, and the second in 2016 in a shelter in the city of Santa Cruz da Conceição. In total, 24 parasitological examinations of feces from collective kennels and 127 blood counts were conducted. In both editions, a large number of dogs exhibited thrombocytopenia and hyperproteinemia. We also identified cases of anemia and changes in the leukocyte counts, which were consistent with infectious diseases. Most fecal samples tested positive for intestinal parasites. These findings can be partially attributed to the substantial number of dogs in both shelters, which poses challenges for sanitary control.

The veterinarian has to frequently assess blood tests in equine medicine. The reference values are adapted from international literature, based on examinations of healthy horses, under a standardized climate and physical activity. This study aimed to compare the blood values obtained from sports horses and traction horses, taking into account the type of activity performed. Anamnesis and hematology data from 76 animals were used: 32 members belonged to the Traction Group (TG), corresponding to equines from traction activity (cart horses) and 44 members belonged to the Sport Group (SG), corresponding to equines used in obstacle jumping, both groups were from the Pirassununga region, State of São Paulo. Complete blood counts and plasmatic fibrinogen dosage were evaluated. The animals from the TG had lower erythrocyte count and hematocrit values. The animals from the TG had greater leukocyte values in the leukogram compared to the animals from the SG. Cart horses were found to have lower means of hematological values compared to the jumping horses. Moreover, these values were below the normal physiological range for the species.
