The objective was to evaluate the activity against Haemonchus contortus by foliage taken from three tanniferous tree species and fed to Creole male kids experimentally infected with a dose of 350 larvae of H. contortus (L3) kg-1 body weight (BW). Twenty Creole kids weighing 12 ± 2.0 kg were randomly distributed in four treatments: T1 = control without foliage, and the addition of fresh foliage (10 % of the dry matter of the total diet) of Guazuma ulmifolia (T2), Pithecellobium dulce (T3) and Acacia cochliacantha (T4). For sixty days, the activity of the foliage against H. contortus was evaluated by quantifying the reduction in the excretion of eggs per gram of feces; also, the excretion of eggs was associated with the concentration of the blood cell pack, dry matter intake and weight change in animals. The data of the evaluated variables were analyzed in a completely randomized design and a Tukey test was carried out for comparison of means (p < 0.05). The secondary compounds of P. dulce and A. cochliacanta foliage were more effective (p < 0.04) in the control of H. contortus with minor excretion of eggs (1.48 and 1.18 Log10 g-1 of feces), respectively. The hematocrit was different (p < 0.005) mainly in hemoglobin, erythrocytes, lymphocytes and eosinophils; dry matter intake (p < 0.05) and changes in total body weight (p < 0.01) were higher in kids which received P. dulce foliage (T3) with 621.5 g d-1 and 2.4 kg...

The objective of the present study was to determine the chemical composition and in vitro gas production of different legume and wild arboreal pods. Seven seeds of legume browse species, Mexican calabash (Crescentia alata), esculent leadtree (Leucaena esculenta), guamuchil (Phitecellobium dulce), bastard cedar (Guazuma ulmifolia), needle bush (Acacia farnesiana), mimosa (Mimosa sp.) and elephant ear tree (Enterolobium cyclocarpum). Were evaluated for their chemical composition (g/kg DM) and in vitro gas production pattern. Crude Protein was higher for L. esculenta (220) and lower for G. ulmifolia (70). Neutral and acid detergent fiber were higher for G. ulmifolia (687 and 554) and lower for A. farnesiana (267 and 176). Lignin was higher for Mimosa sp. (219) and lower for P. dulce (81). Total gas production (ml gas/g DM) of P. dulce (187) and E. cyclocarpum (164) were higher (P<0.001) than Mimosa sp. The lowest values were for C. alata (108), G. ulmifolia (102), L. esculenta (99) and A. farnesiana (90). The nutritional characteristics of L. esculenta and A. farnesiana might be used as supplements in ruminant diets, due to their major content in CP and in vitro digestibility, representing an alternative protein supplement during dry season.
