Abstract: The observation that P. haemolytica is capable of producing lung lesions identical with changes seen in enzootic pneumonia has been confirmed. The macroscopic and histopathological features of such lesions produced by P. haemolytica, type A, were indistinguishable from those caused by type T. In the gross pathological picture produced by P. multocida and Staph. aureus there was more extensive involvement than in most of the P. haemolytica infections. The basic histological lesion, however, was similar in all three. No lung changes were produced with E. coli or Strep. viridans. Inoculation by intratracheal catheter of a psittacoid agent resulted in a clinical syndrome identical to that described by previous authors. The pulmonary changes also corresponded essentially to those seen by previous investigators in experimental infections and in naturally occurring ?atypical pneumonia?. A combination of the PLV agent and P. haemolytica led to the production of lesions characteristic of both agents without any clear-cut influence of one infection on the course of the other, either clinically or pathologically. Although febrile responses and lesions ascribable to P. haemolytica were more frequent in sheep pretreated with PLV agent, the numbers involved were too few and the differences too small to permit any general conclusions. |

The objective of this study is to evaluate the bromatological composition, carbohydrate fractionation, in vitro digestibility and gas production of varieties of forage cactus of the genus Opuntia, associated with different phenological phases. The experiment was conducted in a completely randomized design in a 5 × 3 factorial arrangement consisting of five forage cactus varieties of the genus Opuntia ((IPA-20 (Opuntia ficus-indica Mill), Gigante (Opuntia ficus-indica Mill), Erect Prickly Pear (EPP) (Opuntia stricta Haw), African Prickly Pear (APP) (Opuntia undulata) and F-08 (Opuntia atropes Rose)). and three phenological phases (young, intermediate and mature). The concentrations of neutral detergent fiber and the C ratio of carbohydrates were lower in the Erect Prickly Pear (EPP) variety, in this same variety, a higher proportion of pectin was observed along with the giant variety and higher in vitro digestibility, with similar digestibility for the African Prickly Pear (APP) and F-08. The concentration of total carbohydrates was higher in the IPA-20 variety since the gas production adjusted by the bicompartmental model was higher for APP. Was observed in all varieties greater concentration of neutral detergent fiber and the C fraction of the carbohydrates in the mature cladodes. In vitro digestibility of mature phase was also superior in all varieties except APP. The Erect Prickly Pear and African Prickly Pear varieties present best nutritional value for feeding ruminants and mature phase is the least relevant.
