Performance of Broilers Fed Diets Supplemented with Sanguinarine-Like Alkaloids and Organic Acids

Phytogenic additives and organic acids in broiler chicken diets

“…Similarly, studies with organic acids also showed no performance difference, in comparison with the negative control and/or the birds fed antibiotics (Gunal et al, 2006;Abdel-Fattah et al, 2008;Vieira et al, 2008;Faria et al, 2009). However, most of the studies that used these additives in broilers were conducted in low health challenge environments.…”

“…Although there are no performance differences between the treatments, the association of phytogenic additves and organic acids can be used in order to improve performance. Additive and/or synergistic effect was observed with the combinations of probiotics and acidifiers (Khosravi et al, 2010), sanguinarine and organic acids (Vieira et al, 2008), essential oils and enzymes (Basmacioğlu Malayoğlu et al, 2010), acidifiers and enzymes (Smulikowska et al, 2010) and phytogenics and probiotics, improving the immune system of the birds (Li et al, 2009).…”

Assessment of Benzophenanthridine and Protopine Alkaloids in Broiler Challenged and Not by Salmonella Heidelberg

“…On the other hand, in the study of Vieira et al (2008a), 21-d-old broilers receiving 50 ppm of a product containing BPA in the drinking water were heavier than the controls. Moreover, Vieira et al (2008b), when evaluating different levels (0, 12.5, 25, 37.5, and 50 ppm) of a BPA product added to the feed as a performance enhancer, observed a higher weight gain in 21-d-old broilers receiving 50 ppm BPA compared with the controls.…”

“…However, on day 21, the birds receiving BPA for the period of one to 21 days of age (BPA 1-21d) were heavier (p<0.05) compared with those receiving BPA from one to six days of age and challenged with S. Heidelber g at six days of age (BPA 1-6 d, SH) ( Table 2). Zdunczyk et al (2010), Vieira et al (2008a), and Vieira et al (2008b) when assessing the performance of broilers treated with BPA, but not submitted to health challenges. Zdunczyk et al (2010) did not observe any differences (p>0.05) in the body weight of BPA-treated broilers relative to the controls neither 8 nor at 21 days of age.…”

“…The strategic use of dietary supplementation with plant extracts in food animals has shown many benefits through its active properties (Vieira et al, 2008a;Vieira et al, 2008b;Hernández et al, 2004). Oliveira (2012) reported that benzophenanthridine (sanguinarine and chelerythrine) and protopine (protopine and alocryptopine) alkaloids are the active principles extracted from Macleaya cordata.…”
