It was evaluated the radiographs alteration of the castor oil bean polymer applied for the filing of induced bone fault in horses. Five animals were evaluated, subjected to a local anesthesia and sedation, proceeding to a surgical induction of a hole in the radio bone, in both members with three centimeters depth perforations. It was used a drill of eight millimeters of diameter. The right member served as a control, without filling induced holes. The holes in left radio were filled with the commercial polymer derived from the castor oil bean. We evaluated the localized swelling and radiological aspects as: the establishment of scores for bone filling, sclerosis and a morphometric analysis of the sclerosis area, in 15, 45, 90 and 180 days of lesion evolution. There was more swelling in local members whose injuries were filled with polymer from castor oil bean. By comparison, the radiographic examination showed better bone filling in the gaps of members control. We concluded that the completion of castor oil bean polymer in bone holes induced in radio of horses, delayed the bone healing, in the radiographic evaluation.

This work was carried out with the objective to evaluate the effect of different carbohydrate sources associated with sunflower oil on performance, carcass characteristics and cuts yields of feedlot sheep. Twenty four lambs were assigned to a completely randomized design with a 2 × 2 factorial arrangement with two sources of neutral detergent soluble carbohydrate, starch or neutral detergent soluble fiber, with and without the inclusion of 4.2% sunflower oil. The treatments consisted of diets containing high content of soluble fiber (17.14% DM) without adding oil, high in soluble fiber (16.35% DM) with inclusion of 4.2% sunflower oil, high starch (30.14% DM) without adding oil and high starch (28.21% DM) with addition of 4.2% of sunflower oil. The animals were feedlot with average initial of 17.7 kg and when reached 35 kg body weight were slaughtered. The different sources of carbohydrate and oil inclusion in the diet not influence the days on feedlot in the dry matter intake and average daily weight gain, but higher feed conversion was observed for the diet with a high percentage of neutral detergent soluble fiber compared to diet high in starch. The carcass weights and yields as well as the commercial cuts were not affected by diets. The performance and quantitative characteristics and carcass cuts of lamb are not affected by different carbohydrate sources and their association with 4.2% sunflower oil.
