Abstract
The objective was to determine the centesimal composition and some physicochemical parameters in the longissimus lumborum muscle from non castrated Santa Ines lambs, fed diets containing different proportions of passion fruit peel, in the following treatments: T1: 100% elephant grass, T2: 90% elephant grass + 10% dried passion fruit peel, T3: 80% elephant grass + 20% dried passion fruit peel, T4: 70% elephant grass + 30% dried passion fruit peel based on the elephant grass natural matter. The inclusion of 30% passion fruit peel in the diet of Santa Inez lambs turned the meat less intensely red (a = 7.40) but with a stronger hue (h = 59.75) than that resulting from the 10% addition. The water retention capacity was higher in the meat of lambs fed 30% passion fruit peel, as well as, shear force (0.50) and pH (6.40), but these values are adequate to assure quality. Protein content, minerals and energy did not change, but neither did their values fall below the level desired by industry. Lipid content was higher in the meat of lambs fed 20% of passion fruit peel. Therefore, the inclusion of 30% of passion fruit peel in the silage of growing Santa Inês lambs is recommended, because it improves the quality and nutritional parameters of the meat.

Objetivou-se determinar a composição centesimal e alguns parâmetros físico químicos no músculo Longissimus lumborum de 16 cordeiros Santa Inês, não castrados, alimentados com diferentes dietas contendo casca desidratada de maracujá, sendo os tratamentos T1: 100% capim elefante; T2: 90% capim elefante + 10% casca desidratada de maracujá; T3: 80% capim elefante + 20% casca desidratada de maracujá; T4: 70% capim elefante + 30% casca desidratada de maracujá com base na matéria natural do capim elefante. A inclusão de 30% de casca desidratada de maracujá na dieta de cordeiros Santa Inês tornou a carne com um vermelho menos intenso (a=7,40), mas com grau de tonalidade maior (h=59,75) em relação àquela com inclusão de 10%. A capacidade de retenção de água foi maior na carne de cordeiros alimentados com 30% de casca desidratada de maracujá, assim como a força de cisalhamento (0,50) e pH (6,40), porém são valores adequados para garantir a qualidade. Os teores de proteína, minerais e energia não se modificaram, mas também não apresentaram valores aquém do que é desejado pelas indústrias. Os teores de lipídios se apresentaram com maior quantidade na carne de cordeiros alimentados com 20 % de casca desidratada de maracujá. Recomenda-se a inclusão de 30% de casca desidratada de maracujá na silagem de cordeiros Santa Inês em crescimento, pois melhora os parâmetros de qualidade e nutricionais da carne.
