Contenido :  ABSTRACT: Objective: Our objectives were to compare the effects of feeding eucalyptus bark or eucalyptus wood chips, both by-products from the pulp industry, on voluntary feed intake, animal performance, and physiological variables of heifers finished on high-concentrate diets. Materials and Methods: Forty-eight British-breed heifers (Angus, Hereford, and their crosses) that were 22 to 24 mo of age and had an initial BW of 355 ± 8 kg were used. Four heifers were allocated to each of the 12 pens (experimental units). The experiment was a randomized complete block design with 2 treatments and 6 replications each. The 2 different fiber sources (wood chips or bark) were included in the fattening diet in the same proportion (8.9% DM basis). The rest of the ingredients in the diet were the same. The final diet was offered 3 times per day, and heifers were fed for 84 d. Results and Discussion: Fiber source (wood chips vs. bark) did not affect ADG or G:F (P > 0.10). However, DMI (P < 0.01), DP (P = 0.04), and hot carcass weight (P = 0.06) were greater in heifers fed with bark compared with those fed with wood chips. Heifers from the bark treatment spent less time (P = 0.02) chewing than heifers from the wood chips treatment. Implications and Applications: In conclusion, bark could be used as a source of fiber for finishing cattle in high-concentrate diets at the same levels as wood chips. This finding is relevant for the feedlot industry because eucalyptus bark has no industrial use... Presentar Todo

Contenido :  Abstract. Introduction: Quillaja brasiliensis (St. A. ?Hil. & Tul) Mart (Quillajaceae) is a species native to South America, which is rich in saponins. Saponins are used in different industries, so there is a constant demand for this type of compound. Based on the wide range of applications for the saponins found in this species, notably as immunoadjuvants, we conducted a comprehensive study of this tree and its saponins. Objective: The purpose of this work is to complete the characterisation of the immunoadjuvant saponin fraction from Q. brasiliensis leaves and further study the saponin fraction obtained from Q. brasiliensis bark. Methodology: Saponin fractions were studied using mass spectrometry in combination with classical methods of monosaccharide and methylation analysis. We performed direct infusion and liquid chromatography/electrospray ionisation ion trap multiple?stage mass spectrometry (DI?ESI?IT?MSn and LC?ESI?IT?MS2). Results: Seventy?five saponins, 21 from leaves and 54 from bark, were tentatively identified according to their molecular mass, fragmentation pattern and chromatographic behaviour. This work represents the first investigation of saponins from the bark of Q. brasiliensis and some of them presented new structural motifs not previously reported in the genus Quillaja. Conclusion: The efficiency and selectivity of the data dependent LC?MS2 method allowed the rapid profiling of saponins from Q. brasiliensis. The results of the monosaccharide and methyla... Presentar Todo
