Adequate design of diets to animal health and productivity is essential in livestock industry. For the above, commonly are use bulky ingredients (fibrous sources) combined with a concentrates ingredients as cereals (energy sources), legumes (protein sources) and mineral concentrates. Mucuna spp. is a tropical legume in which its nutrients characteristics have been underutilized by livestock industry. Mucuna seed have an important nutritional characteristics as feedstuff: 1) Crude protein and energy concentration (dry matter basis) of 20 to 30 % and 15.7 to 24.7 MJ kg-1, respectively; 2) Presence of unsaturated fatty acids; 3) Similar concentration of anti-nutrient factors than other legumes, within which L-3,4 dihidroxiphenilalanine (L-DOPA,) can be easy reduced until no adverse effects on animal growth are noted. In addition, mucuna seed is a feedstuff economically advantageous, since is commonly considered as agriculture waste. The aim of this paper is to present a review of available information about the presence and concentration of nutritional compounds in the seed of Mucuna spp. with high potential for livestock industry.

A experiment was conducted to evaluate the substitution of the crude protein from the ration for the protein from crambe (Crambe abyssinica) meal on the performance of broilers in starter phase (eight to 21 days). A total of 420 male chicks of the Cobb strain were used, distributed in a completely randomized design, with five treatments and four replications of 21 broilers each. The experimental treatments consisted of a control diet without the crambe meal and other substitution of protein from ration for crude protein from crambe meal in levels of 5, 10, 15 and 20%. There was no significant effect for the feed conversion of the chickens, however, there was a decreasing linear effect for feed intake and weight gain of the birds, to the extent that crambe protein replaced the protein ration. A Reduction in the feed intake at 10, 15 and 20% levels of protein substitution was observed. For the weight gain, the lowest values observed were for the 15 and 20% replacement levels, whereas the levels of 5 and 10% did not differ in relation to the control treatment. Therefore, it can be recommended to replace the crambe meal in the feed level of 10% without negatively influencing the weight gain of broilers. [ABSTRACT FROM AUTHOR]

Colombian agricultural sector requires integraed agro-industrial sector to add value to their products and waste generated. Agricultural and agroindustrial use waste as raw materials for secondary metabolites is a subject of interest in research and seeks to respond to the use or destination of such waste through the development of technologies applicable to the Colombian environment. We evaluated peel, seed and pulp of avocado varieties Booth8, Trinidad and Papelillo in states of physiological maturity (MF) and consumption (MC). Characterization made bromatological fiber as soluble carbohydrates (CHOS), lignin (LG), cellulose and hemicellulose (CEL and HEMICEL) and crude fiber (CF) by (Tappi Methods, 1993, 1998), AOAC, 2001. The results were analyzed by ANOVA (P <0,05) using SAS V9.1. CHOS in the two stages of maturity and the three varieties ranged between from 12-38% peel, 20-35% pulp and 17-35% seed; CEL-HEMICEL 8-50% peel, 7-26% pulp, 1-5% seed, which can be a useful adjunct to biotechnological processes. The pulp of the three varieties has high nutritional value for their contents of protein, fiber and minerals. The composition of the shell and seed could be important for animal dietary supplements or recovery of solis for agricultural production. [ABSTRACT FROM AUTHOR]
