Meat quality of lambs fed silk flower hay (Calotropis procera SW) in the diet

Abstract

-The objective of this work was to evaluate the influence of using silk flower hay replacing corn and soybean meal on physical-chemical and sensorial traits of lamb meat. It was used 32 intact Morada Nova male lambs (12.7 ± 2 kg initial body weigth) on feedlot system, distributed in a completely randomized design with four levels (0, 15, 30 and 45% on dry matter basis). The use of silk flower hay in the diet influenced quality of meat and carcass, leg weight, tissue composition, moisture, juiciness and flavor. Replacing corn (26.67%) and soybean (3.33%) with silk flower hay does not affect the tissue composition, ratios and muscularity index of leg and physical-chemical parameters of semimembranosus muscle of Morada Nova lambs.Key Words: carcass, flavor, Morada Nova, muscularity, native breed Qualidade de carne de cordeiros alimentados com feno de flor-de-seda (Calotropis procera SW) na dieta RESUMO -Objetivou-se avaliar a influência do uso de feno de flor-de-seda em substituição ao milho e ao farelo de soja nas características físico-químicas e sensoriais da carne de cordeiros. Utilizaram-se 32 cordeiros Morada Nova, machos não-castrados (12,7 ± 2 kg de peso vivo inicial), em confinamento, distribuídos em delineamento inteiramente ao acaso com quatro níveis (0, 15, 30 e 45% com base na MS). A utilização de feno de flor-de-seda na dieta influenciou a qualidade da carcaça e da carne, o peso da perna, a composição tecidual, a umidade, a suculência e o sabor. A substituição do milho (26,67%) e da soja (3,33%) pelo feno de flor-de-seda não altera composição tecidual, relação e índice de muscularidade da perna e os parâmetros físico-químicos do músculo semimembranosus de cordeiros Morada Nova.Palavras-chave: carcaça, flavour, Morada Nova, muscularidade, raça nativa Revista Brasileira de Zootecnia

Physicochemical and sensory characteristics of meat from lambs fed diets containing mulberry hay

“…Contrarily to what it was observed in the present study, several authors have reported that the inclusion of alternative forage sources in the diets of lambs may influence meat sensory quality (Madruga et al 2005;Costa et al 2011;Moreno et al 2015). Madruga et al (2005) observed differences in the meat from Santa Table 4.…”

“…The values found in this study are thus similar to those described in the literature. Costa et al (2011) observed no changes in meat colour using percentages (15, 30, and 45%) of silkflower hay replacing the concentrate in the diet of Morada Nova lambs finished in the feedlot. Similarly, Moreno et al (2015) reported no changes in meat colour when evaluating saltbush hay (Atriplex nummularia) in finishing diets for Santa Ines lambs in the feedlot.…”

“…Water-holding capacity (WHC), cooking loss (CL), shear force (SF), and sarcomere length (SL) in the Longissimus lumborum muscle of lambs fed diets containing mulberry hay. Ines lambs fed diets containing four different types of forages; Costa et al (2011) reported the influence of silk flower hay and Moreno et al (2015) reported the effect of saltbush hay on meat sensory quality of Santa Ines lambs. Scores assigned by the judges on a scale of 1 (dislike extremely) to 9 (like extremely) indicate that meat from lambs fed diets containing mulberry hay had good acceptability, what supports the potential use of this alternative source of nutrients in lambs feedlot diet without modifying the meat sensory attributes.…”

Sugarcane Production Based on Mineral and Organic Nitrogen Fertilizers for Ruminant Feeding

“…However, they are within the range found in the literature for this variety. ----------------------------%--------------------------- Similar dry matter results were found by Costa et al (2011). They obtained 30.4% of dry matter also in the fourth punch, whereas Cruz et al (2009) found an average of 30.5%.…”

Chemical Constituents and Uses of Calotropis Procera and Calotropis Gigantea – A Review (Part I – The Plants as Material and Energy Resources)

“…In NW Brazil [114], and to a smaller extent in parts of India [115], silk flower hay (SHF, C. procera SW.) has been reported to be suitable for feeding goats, sheep, and camels. In sheep and goat farming, it was noted that substitution of corn and soybean by silk flower hay of up to 30% did not decrease the nutrient uptake by Morada Nova lambs [116] and did not decrease the sensory attributes of their meat [117] or important attributes of the milk of the goats [118].…”
