Aiming to evaluate the levels of crude glycerin (0, 7, 14 and 21% based on dry matter) in replacement of ground corn on the biological rhythm of ingestive behavior and physiological parameters of lactating goats. Eight crossbred Anglo-Nubian goats were used, which were distributed in simultaneous double Latin square (4x4). The animals were observed for feeding time, rumination and idleness during 24 hours. The respiratory rate (RR), heart rate (HR), rectal temperature (RT) and sweating rate (SR) were assessed in the morning and afternoon. Crude glycerin levels did not affect intake, rumination, idleness time, dry matter intake efficiencies, and chewing patterns of the goats. In addition, there was a reduction in the intake of DM, NDF, the intake efficiency (g NDF/h), and rumination efficiency in g DM/h and g NDF/h for the levels tested. The RR, HR and RT in the morning reduced with supplementation. In this same sense, the RR and HR in the afternoon reduced with the crude glycerin. Climatic conditions increased the RR, RT and SR of the goats in the afternoon. Therefore, it is recommended to replace up to 7% of ground corn based on dry matter by crude glycerin.

Background: Aneurysm is a dilation and a weakening of the vessel, usually 2 times higher than the normal diameter of the vessel. Considering the complexity of the definitive diagnosis of iliac artery aneurysm, it is necessary to use technology by imaging, aiming an early diagnosis. Thus, application of Doppler ultrasound allows the study of the horse's vascular system allowing various types of diagnoses among these members and vascularization for diagnosing thrombi in the abdominal aorta and mesenteric arteries in side verminotic aneurysm. The aim of this study was to describe the occurrence of two cases of aneurysm involving the aortic-iliac diagnosed by Doppler ultrasound. Cases: The study describes two cases of the aneurism in horses diagnosed by Doppler ultrasound at the Veterinary Hospital of UPIS. The animals showed clinical signs of edema in the pelvic limb, with varied degree of lameness 3 to 4, pain and wound did not heal and septic arthritis. The final diagnosis was obtained by Doppler ultrasound. In case one, Doppler ultrasound analysis indicated high arterial distension and blood flow disorganized, suggesting aneurysm. The patient did not respond adequately to therapy and due to the severity of these changes, the euthanasia was performed for definitive diagnostic. On the other hand, in case two, in the imaging examination, it was diagnosed with a dilated aortic Iliac left four times larger than the right and disorganized blood flow suggesting aneurysm. As a result of diagnosis and unfavorable prognosis, it was decided to stop sports activities by the animal mainly due to the progressive increase of the aneurysm. Discussion: Between the two reported cases, one animal died with excessive extension of injury and in another it was possible to establish a palliative treatment being observed improvement in clinical symptomatology. The aneurysm was defined as a dilation of the artery, which may be congenital or acquired. In this case, it was not possible to define the main cause. However, their characteristics, visualized through ultrasound and necropsy corroborate to described in the literature, such as slow growth, achieve considerable volume may compress, displace and destroy neighboring structures. They also tend to increase in size until they break, causing bleeding. In the reports one and two it was found aneurysm verum, where in the animal of the report one was carried out euthanasia due to the rupture of the iliac artery. Surgical procedures are not usually indicated, due to the rapid evolution of the aneurysm culminating in hemorrhage and death of the patient. Ultrasound in these cases was also able to measure the extent of the lesion, to evaluate the blood flow and consequently the turbulence of blood. It is a disease with an unfavorable prognosis, by the progressive increase of the aneurysm or due to the possibility of aneurysm rupture. According to the results of this report can be concluded that Doppler ultrasound should be included in the routine practice of equine veterinary clinic, mainly in athletic horses to diagnose arterial lesions with complicated detection on clinical examination. The clinical symptomatology presented by the animals can be included in routine practice. The aneurysm of the iliac artery if was not diagnosed in time can cause death of the animal, however, if it was detected early, it can be established a palliative treatment extending the duration of animal life.

Knowledge on climate and its action on the behavioral and physiological responses of animals are prevalent for the production system of the cattle industry. Therefore, The aim of this study was to evaluate the effect of season and time of day on physiological parameters of Morada Nova sheep in Alto Medio Gurguéia region. Eight arrays of Morada Nova were studied, in a completely randomized 4x2 factorial block, in four periods of the day, at 7-8 a.m., 10-11 a.m., 2-3 p.m and 5-6 p.m, and two seasons: E1 (hot and dry) October-November, and E2 (warm and wet) March-April. The physiological parameters respiratory rate (RR), heart rate (HR) and rectal temperature (RT) were measured weekly, performing four collections per season, totaling 8 samples. The ohysiological parameters respiratory rate, heart rate and rectal temperature were influenced (P<0.05) by season and by time of day, with higher values for all variables in the hot and dry season in the afternoon, primarily at 5-6 p.m, probably due to increased incidence of solar radiation and thus heat accumulation throughout the afternoon.

This work aimed to evaluate and correlate the thermoregulatory characteristics of crossbred cows (Holstein x Gir) submitted to three different periods of exposure to solar radiation with some meteorological variables and their effects on milk production. Were twelve lactating cows divided into three groups consisting of four animals each, all of the third lactation, up to five years of age and approximately 50 days of lactation, submitted to different periods of exposure to solar radiation. Milk production per cow in kilograms was recorded in two daily milkings. The respiratory rate (RR), heart rate (RR), rectal temperature (RT) and the decline in milk production (DPL) obtained by the difference between the weights of the morning and afternoon milkings per cow during the experiment were collected four times a week in May and June 2011. The results revealed that the temperature and humidity index (THI) for cows exposed to two hours of solar radiation was higher than values considered critical for lactating cattle. The group presented three upper critical values for all thermoregulatory characteristics of animals when compared with groups one and two. The thermoregulatory characteristics of animals of groups two and three groups were positively correlated with the decline in milk production and differently with meteorological variables.
