RESUMENTaninos, contenido proteico y composición de áci-dos grasos de semillas de algunas especies de Vicia L. de Turquía.Las semillas oleaginosas de seis especies de Vicia (Leguninoas) fueron investigadas por su proteína, contenido en taninos y composición en ácidos grasos. El contenido de proteína en las semillas vario entre un 21.87%-31.33%. El contenido de taninos en las semillas vario entre un 0.13%-1.07%. La composición de ácidos grasos de estas seis diferentes especies fue determinada por GC mediante los esteres metílicos de sus ácidos grasos. Las semillas oleaginosas de las especies de Vicia contienen ácidos palmítico y esteárico como componentes mayoritarios entre los ácidos grasos saturados, con pequeñas cantidades de ácido mirísti-co, ácido palmitoleico y ácido margárico. Los ácidos grasos insaturados mayoritarios encontrados en las semillas oleaginosas fueron el ácido oleico, ácido linoleico y ácido linoléni-co. En este estudio, el contenido total de ácidos grasos saturado de las especies de Vicia vario entre 18.5 y 22.4% mientras que el de insaturados vario entre 71.1 y 80.3%. The seedoils of six Vicia species (Leguminosae) were investigated for their protein, tannin contents and fatty acid compositions. The protein contents of the seeds were found to be between 21.87%-31.33%. The tannin contents of the seeds were found to be between 0.13%-1.07%. The fatty acid compositions of these six different species were determined by the GC of the methyl esters of their fatty acids. The oilseeds of Vicia species contain palmitic and stearic acids as the major component of their fatty acids, among the saturated acids, with small amounts of myristic, palmitoleic and margaric acids. The major unsaturated fatty acids found in the oilseeds were oleic, linoleic and linolenic acids. In this study, the total saturated fatty acids of Vicia species were between 18.5 and 22.4% while the total unsaturated fatty acids were between 71.1 and 80.3%.

“…Throughout the world today there is also a growing resistance against the use of animal protein sources in animal feeding (Brand, 2002). It is desirable, therefore, that the nutritional potential of alternative plant protein feeds, such as grain legumes is fully exploited (Brand et al, 2004).…”

“…Phosphorus concentration varies between 4.2 g/kg (L. angustifolius) and 7.6 g/kg (L. luteus). No extreme differences in trace mineral concentrations occurred except for the manganese concentration of L. albus, which containes approximately 10 times more manganese than the other legume grains (Brand et al, 2004).…”

“…Protein sources are becoming scarcer and more expensive, especially for use in animal feeds (Brand et al, 2004a;Laudadio & Tufarelli, 2011). Depending on the feeding phase (pre-starter, starter, grower or finisher), protein composes up to 22.5% of a balanced diet (Brand & Gous, 2006).…”

Feed costs contribute the largest proportion of the input costs of slaughter birds in an intensive ostrich production unit. Alternative, cheaper feedstuffs, such as lupins (sweet and bitter cultivars), were therefore evaluated to determine the optimal lupin inclusion level in ostrich rations without affecting feed preference and intake. Sixty South African Black ostriches were randomly divided into ten paddocks of six birds per paddock. Three trials, with five different experimental diets, were conducted to investigate the diet preference of grower ostriches in a free-choice system. Feed and water were supplied ad libitum. The position of the diets in the successive paddocks was varied by rotating the five feed troughs in a clockwise direction, but within each paddock the position of each feeder and diet stayed the same throughout the three trials. In the first two trials, sweet (trial 1) or bitter (trial 2) lupins replaced soybean oilcake meal to have 0, 7.5, 15, 22.5, and 30% lupin inclusion levels in the diet. In trial 3 the soybean oilcake meal was replaced with either sweet or bitter lupins to have dietary inclusion levels as follows: 0% lupins, 15% sweet, 15% bitter, 30% sweet, or 30% bitter. The daily intake per group for each diet was monitored over a period of five days each. The average initial body weight of the birds was 73.6 ± 0.5 kg. No interaction was found between day and diet for the three trials and dry matter intake (DMI) did not differ between the five treatments for any of the three trials. In the second trial the birds tended to show a preference for the 7.5% bitter lupin inclusion level and discriminated against the 15% and 30% bitter lupin inclusion levels. Regression analysis of DMI on lupin inclusion rates revealed no significant trends. In conclusion, the study revealed that soybean oilcake meal can be replaced in the diets of grower ostriches by sweet lupin inclusion levels up to 30%, without any significant detrimental effect on diet preference and feed intake.
