The relationship between host nutrition and the development of clinical fascioliasis in sheep was investigated by comparing the course of the disease, firstly in animals given the same number of Fasciola hepatica metacercariae and fed rations containing 6 or 13% crude protein, and secondly in chronically infected sheep transferred from high to low protein diets. In the first experiment, it was found that sheep on the lower protein ration experienced more rapid anaemia, hypoalbuminaemia and weight loss, and died earlier than their better fed counterparts. Since the fluke burdens were comparable in both groups it was concluded that the advantages displayed by the latter reflected their freater capacity to withstand the parasites' pathogenic effects rather than a superior ability to limit infection. This was supported by the results of the second experiment demonstrating a faster development of disease in infected sheep when switched from high to low planes of nutrition. The importance of reduced appetite was also studied by comparing the clinical indices of infected sheeps with those of worm-free animals maintained on the same level of feed in-
take. It was found that loss of appetite contributed substantially, although not entirely, to the weight loss and hypoalbuminaemia, but in itself apparently had little effect on the attendant anaemia. |

Legumes shrubs such as Cratylia argentea have an ability to thrive in environments with low water availability and poor soil. On the other hand, forage grasses such as Tifton 85 have a greater demand for inputs to be productive. The objective of this study was to evaluate the performance of growing and finishing Lacaune lambs fed Cratylia argentea hay as an alternative to Tifton 85 (Cynodon spp). Twenty-four Lacaune lambs aged between five and six months (average body weight [BW] 21.50 ± 3.38 kg) were arranged in a split-plot randomized block design. The plots consisted of different Cratylia to Tifton 85 hay proportions (0, 20%, 40%, or 100%, dry matter [DM] basis) as a roughage replacement in the total diet. The subplots represented two evaluation times, entitled “initial period” and “final period”, which consisted of the early seven days of total feces and urine collection, and the last seven days of the experiment, respectively. The lambs were blocked by weight with six replicates per treatment. The results show that the level of Tifton 85 replacement for Cratylia hay in the roughage portion of the lamb diet did not influence (P > 0.05) weight gain (WG), dry matter intake or dry matter digestibility; feed conversion, feed efficiency; and the evaluated nitrogen balance variables. The digestibility coefficient of neutral detergent fiber decreased linearly as Tifton 85 replacement for Cratylia level was increased, which probably happened due to the presence of highly lignified material within the Cratylia hay. However, the alternative legume maintained animal performance of Tifton 85. In conclusion, Cratylia hay can be recommended as a potential substitute for Tifton 85 hay, which requires greater inputs for the production. Cratylia may be considered a feeding strategy for livestock production, especially for smallholder livestock systems and regions with unfavorable soil and climate.
