Four treatments with four replications were evaluated. The treatments were: T1 = 100% Kikuyu (Pennisetum clandestinum) grass hay (KGH); T2 = 25% Buddleia skutchii leaves (BSL) + 75% KGH; T3 = 50% BSL + 50% KGH, and T4 = 75% BSL + 25% KGH. The highest (P < 0.05) dry matter intake (DMI) was for T2; the neutral detergent fibre (NDF) intake for both T1 and T2 (535 and 563 g per day, respectively) were similar (P > 0.05) and both were higher in comparison with the rest of the treatments. Digestibilities of dry matter (DM), crude protein (CP), NDF and acid detergent fibre (ADF) were not statistically different (P > 0.05) for treatments T1, T2 and T3, and both T1 and T2 were significantly (P < 0.05) higher than T4. The daily live weight gains (DLWG; 19.5 and 19.0 g per day, respectively) were similar for both T1 and T2, and significantly higher than T3 and T4. The total wool production (WP) and manure production results were not statistically different between treatments (P > 0.05). Nevertheless, there was a clear tendency in reduced DMI, digestibilities and DLWG when replacing KGH with 50 or 75% of BSL. In addition, a basic economic evaluation was carried out.

This research took place in five indigenous communities of Chiapas, Mexico. By means of interviews with producers, a list of 37 species was obtained, of which 14 were selected for evaluation based upon: a) their frequency of use; b) presence of foliage during the drought season (winter); c) local abundance and d) chemical composition and concentration of toxic substances. Among the 14 selected species, six were shrubs and eight were trees. All these species were available all year round. The 14 species showed invasive tendencies and different quantities outside the communities than inside the communities. The values of ecological importance (1.9-4.4) were similar or higher to those found (1.96) in oaks (Quercus spp.), which is the dominant tree species in the region. The foliage of the 14 species contained crude protein (CP) levels of 7.2-22.3%, gross energy (GE) between 2.9-4.5 k&/g; neutral detergent fiber (NDF) of 21-59%; acid detergent fiber (ADF) of 18-5 1%; tannic acid 0.42-0.69 g/100 g, absence or low content of cyanogenic glucosides and low, moderated or high contents of alkaloids. Based on the distribution patterns, abundance, frequency of use and chemical composition, Rapanea juergensenii, Buddleia sp., Eupatorium semialatum and Ostrya oirginiana, are considered as feasible to be incorporated into

Based on the indigenous Tzotzil Botanical Classification, three Buddleia groups were taxonomically identified. Group 1 includes the species Buddleia skutchii and Buddleia cordata, group 2, Buddleia americana and Buddleia crotonoides, and group 3, Buddleia parviflora and Buddleia nitida. Even though all these groups have been used as fodder, the most frequently used are the species in group 1, which are the most common species with the widest distribution patterns. Based on their chemical composition, the species of higher nutritional values were B. skutchii and B. crotonoides (crude protein (CP), 10.6% and 9.3%; neutral detergent fiber (NDF), 37.5% and 33.7%; in vitro dry matter digestibility (IVDMD), 75.9% and 58.2%; and digestible energy (DE), 3.3 and 2.5 Mcal/kg). The first one has been recommended for sheep feeding based on its high nutritional value. During an intake and digestibility trial, B. skutchii leaves substituted 50% of Kikuyo grass (Pennisetum clandestinum) without decreasing dry matter (DM) intake and digestibility. These results suggest that the systematic incorporation of B. skutchii into existing sheep production systems could Animal Feed Science and Technology 80 (1999) 123±134

The chemical composition results on a dry matter basis were as follows: the crude protein (CP) content ranged from 8.4% in Q. rugosa to 27.7% in M. leucantha. Neutral detergent fiber (NDF) ranged from 39.0% in M. leucantha to 58.3% in Q. rugosa and Acid detergent fiber (ADF) varied from 30.8% in M. leucantha to 56.8% in Q. rugosa; Gross energy (GE) contents were 3.0 kcal/g or even greater. Tannic acid was detected from 0.25 g/100 g in E. chiapasana to 1.1 g/ 100 g in Q. rugosa; there were no cyanogenic glucosides detected in the samples, and no alkaloids were encountered in Q. rugosa and A. acuminata, but E. chiapasana showed higher alkaloid content than the other trees. Q. rugosa had the highest foliage production (6.9 kg DM/plant/cut), while E. chiapasana had the lowest production (1.2 kg DM/plant/cut). In an in vivo intake and digestibility trial, the leaves of M. leucantha fed as a sole diet for sheep had the best composition values, higher (P<0.05) in vivo dry matter intake (IVDMI-L) (628 g/day) and in vivo dry matter digestibility (IVDMD-L) (76%) of the five evaluated species. Therefore, the foliage of M. leucantha was included in the sheep's diet in a growth and digestion trial at 0%, 25% and 40% levels of inclusion replacing alfalfa (M. sativa); in vivo CP intake (IVCPI-D) (106.9 g/day), in vivo CP digestibility (IVCPD-D) (67.5%), and live weight gain (LWG) (75 g/day) were higher (P<0.05) in sheep fed with diets including M. leucantha leaves at 40% level of inclusion.
