Qualidade da carne de fêmeas suínas alimentadas com diferentes concentrações de ractopamina na dieta

Abstract: RESUMOAnalisaram-se as qualidades física, química e sensorial, bem como o perfil de ácidos graxos da carne de fêmeas suínas alimentadas com dietas com concentrações crescentes de ractopamina. Foram utilizadas 468 fêmeas, com peso inicial de 84,77±7,20kg, alojadas em 36 baias e alimentadas com dietas contendo 0, 5, 10 ou 15mg de ractopamina/kg. Após o período de 28 dias, dois animais de cada baia, depois de passarem por 15 horas de jejum sólido, foram abatidos. Uma amostra do músculo Longissimus da meia carcaça… Show more

“…The value reported when using 10ppm (20:1) was the lowest and closest to the recommended ratio. Although, all values are high, they were close to other values seen in the literature (WEBER et al, 2006;WATANABE et al, 2012).…”

“…Results are contradictory with some studies not showing a significant difference in fat profile (WEBER et al, 2006;WATANABE et al, 2012), while others observed differences for some fatty acids (ENGESETH et al, 1992;PERKINS et al, 1992;CARR et al, 2005). Furthermore, older studies evaluated fewer fatty acids, providing limited knowledge into the fatty acid profile.…”

“…This result proves that the use of CBB in a qualitative feed restriction program leads to a reduction in the fat content of the carcass but does not alter the composition of the fatty acids. Watanabe et al (2012) found no effect on the concentration of fatty acids in longissimus dorsi muscle samples from females fed diets with increasing levels of inclusion of ractopamine; even when the fat deposition rate decreased, the profile of the fatty acids was not changed.…”

“…Watanabe et al (2012) evaluated the use of ractopamine in diets for female pigs and observed no effect on the arachidonic fatty acid content, which can be explained because the AG composition of the pig muscle is obtained from the diet. Therefore, the fatty acid content provided by the diet was not enough to increase the average composition of the fatty arachidonic acid.…”

“…As várias práticas de uso, bem como as interações com os componentes da dieta e fatores experimentais adversos contribuem de certa forma para a limitação de sua magnitude. Dentre esses fatores, os mais destacados são: o nível de inclusão na ração e o tempo de fornecimento do produto, os níveis de lisina e a relação lisina/energia metabolizável, a linhagem genética/sexo e o programa alimentar adotado (CAMPBELL, TAVERNER, 1988;STAHLY, BARK, 1991;SMITH et al, 1995;SCHINCKEL et al, 2001, SCHINCKEL et al, 2002CANTARELLI, 2007;SANCHES et al, 2010;WATANABE et al, 2012).…”
