Sixty steers were fed during first winter with different levels and source of protein. The steers grazed on improved pastures until reached 350 kg of liveweight,
assigned to a finishing period on pastures-P (n=30) or grain-G (n=30). Treatments were: T1) P13-P: diet with 13% of crude protein (PC) and fattened on P; T2) P13-G: 13% PC, fattened on G; T3) P15-P: 15% PC fattened on P; T4) P15-G: 15% PC fattened on G; T5) P17-P: 17% PC fattened on P; T6) P17-G: 17% PC fattened on G; T7) U100-P: 15% PC, using urea 0.5% of diet, fattened on P, T8) U100-G: 15% PC, urea 0.5% of diet fattened on G; T9) U50-P: 15% PC urea1% of diet, fattened on P, T10) U50-G:15% PC urea1% of diet fattened on G. The aim was to evaluate the effect of the combination of the diets (first winter stocking and finishing periods) on
carcass and meat quality (subcutaneous fat cover-SF, meatcuts/fat ratio- C:F, color of fat-FC and meat-MC, marbling- Marb). There was a clear effect (P<0.05) of the
finishing period in SF, C:F, FC and MC. Grain diets improved FC and MC, presenting higher values of SF and lower C:F ratio than grass fed animals. It was not observed
any clear effect of levels and source of protein in carcass and meat quality. Comparing T1 vs. T2, steers form T1 showed differences (P<0.05) on SF and Marb. Those results suggest that the level of protein could affect the growth of the animals and their tissue composition considering the finishing diet regimes. |

Abstract:Enterotoxemia caused by Clostridium perfringens type D is one of the most prevalent clostridial diseases of sheep. The lesions of
the acute form of this disease, particularly the cerebral lesions, are well characterized; however, detailed descriptions of the cardiac and pulmonary lesions are lacking. Here we describe cardiopulmonary lesions in experimental acute type D enterotoxemia in sheep and determine the role of epsilon toxin (ETX) in the development of these lesions. Four groups of 6 sheep were intraduodenally inoculated with either a wild-type C. perfringens type D strain; its etx knockout mutant, which is unable to produce ETX; the etx mutant complemented with the wild-type etx gene, which regains the ETX toxigenic ability; or sterile culture
medium as a control. All sheep were subjected to postmortem examination within 24 hours of inoculation. Lesion scores were compared between groups for pulmonary edema; hydrothorax; ascites; hydropericardium; endocardial, myocardial and epicardial hemorrhages; microscopic lesions of acute myocardial degeneration and necrosis; and myocardial, endocardial, and epicardial edema, hemorrhage, and inflammation. Only sheep inoculated with the wild-type and complemented ETX-toxigenic bacterial strains developed cardiopulmonary lesions, which were present in varying degrees of severity and proportions. These lesions were not present in sheep inoculated with the etx mutant or in the negative control. We conclude that severe acute cardiopulmonary lesions in sheep with experimental enterotoxemia are associated with the capacity of the strains to produce ETX. These changes are likely contributors to the clinical signs and even death of affected animals.
