Grão de girassol na alimentação de suínos em crescimento e terminação: digestibilidade, desempenho e efeitos na qualidade de carcaça

Abstract

ResumoO uso do grão de girassol (GG) para suínos em crescimento e terminação foi avaliado através de um ensaio de digestibilidade e um experimento de desempenho. Na avaliação zootécnica 48 suínos, com peso médio inicial de 19,78 kg foram tratados com 4 dietas (com 0%, 5%, 10% e 20% de GG) durante 4 períodos (crescimento I e II, terminação e total). Ao abate as carcaças foram eletronicamente tipificadas. A energia digestível e metabolizável do GG foi de 3234 e 3223 kcal/kg, respectivamente. AbstractTwo experiments (a digestibility and a performance tests) were carried out to evaluate sunflower seed (SS) as swine feeding on growing and finishing phases. To performance evaluation 48 pigs, with 19.78 kg liveweight were allotted to four treatments (diet without SS, 5%, 10% and diet with 20% of SS) and they were evaluated during four periods (growing I and II, finishing and total period). All animals were slaughtered and submitted to an electronic carcass evaluation at the end of the experiment. The digestible and metabolizable energy values of SS were 3234 and 3223 kcal/kg, respectively. There were regression effect (P<0,05) on performance of the following characteristics for the levels of SS: daily feed intake (DFI): DFI(growing I) = 2066.500 -20.990X; DFI (growing II) = 3098.470 -36.015X; DFI (finishing) = 1 Professores Doutores..

Sunflower meal and supplementation of enzyme complex in diets for growing and finishing pigs

“…Treat -treatment; CV -coefficient of variation; β FG (%) -percentage of sunflower meal in the diet; γ -Interaction between treatments and SM (%); ns -does not present significance by the F test (P>0.05); * -(P < 0.05); Q -quadratic effect (P ≤ 0.05) of the sunflower meal level; L -linear effect (P ≤ 0.05) of the sunflower meal level; ns/NS -no significant effect SM%-0.0111 (SM%) 2 (R 2 = 0.95), with maximum point reached at the level of 8.16% inclusion. These results differ from other studies that did not report any influence of the inclusion of sunflower meal based feed on backfat thickness (SHELTON et al, 2001;SILVA et al, 2002b;SILVA et al, 2003;COSTA et al, 2005;CARELLOS et al, 2005). Relative to the amount of total fat in the pig carcass, animals fed increasing levels of sunflower meal also showed no effect (MILINSK et al, 2007).…”

“…In extensive research on the existence of influential effects of the addition (SILVA et al 2002b;COSTA et al, 2005;COLINA et al, 2010). Similar results were found by Silva et al (2003), evaluating sunflower seed in the fodder diet of growing and finishing animals. As more productive swine strains are developed, animals with greater potential for lean meat deposition develop.…”

“…No differences were observed for the same variables up to the inclusion of 15.0% sunflower cake in the fodder diets either (SILVA et al, 2002b). There was, however, a negative correlation between carcass weight and the inclusion of sunflower seed in diets for finishing pigs (SILVA et al, 2003). However, the inclusion of sunflower meal in swine fodder diets did affect backfat thickness (BT) (P < 0.05; Treat -treatment; CV -coefficient of variation; β SM (%) -percentage of sunflower meal in the diet; γ -Interaction between treatments and SM (%); nsdoes not present significance by the F test (P > 0.05); * -(P < 0.05); Q -quadratic effect (P ≤ 0.05) of the sunflower meal level; L -linear effect (P ≤ 0.05) of the sunflower meal level; NS/ns -no significant effect.…”

“…Colina et al (2010) used 17.5% inclusion of sunflower meal in diets for piglets of 15 days of age in their experiment, which suggested that the inclusion of this ingredient can also be used in the starter phase, in spite of its high fiber content. Silva et al (2003), on the other hand, reported inclusion of only 5.0% sunflower seed in the feed without affecting productive parameters during that phase. In comparison with soybean meal, Trombetta and Mattii (2005) used an 11.0% dehulled sunflower seeds inclusion in the fodder.…”
