Flavonoids and mannanoligosaccharides in broiler diets

Abstract

campus, and aimed at evaluating the effect of the inclusion of flavonoids along with mannan oligosaccharides (MOS) as compared to other additives on the performance, carcass and parts yields, and meat quality of broilers reared from 1 to 42 days of age. A total number of 1500 Cobb broilers were distributed according to a completely randomized experimental design into five treatments, with six replicates of 50 birds each. Treatments consisted of a control group, probiotic 1, probiotic 2, antibiotic, and flavonoids+MOS. For the period of 1 to 42 days of age, there were no differences among treatments as to daily weight gain, feed intake, mortality, and final body weight, but a significant difference was found for feed conversion ratio for the flavonoids+MOS treatment. Carcass and parts yields were not significantly influenced by the treatments. Tbars number, which indicates meat fat oxidation index, was significantly different in both refrigerated and frozen meat. The lowest oxidation index was obtained with the flavonoids+MOS treatments. Under the conditions of the present study, the supplementation of broiler diets with flavonoids+MOS was effective.

Performance, intestinal microflora, and blood constituents in finishing turkeys fed diets supplemented with dietary mannan oligosaccharide and live yeast

“…In agreement with our results, in a comparative study, Cömert (2004) reported that the BW and gain were not affected by the dietary MOS and probiotic addition in bronze turkeys which advanced in .2 MOS -mannan oligosaccharide; P -probability; SEM -standard error of the means (Pooled); NS -non-significant; HDL -high density lipoprotein; LDL -low density lipoprotein weeks (from 7 to 21 weeks). Similarly, Batista et al (2007) reported that the BW and gain were not affected by both prebiotic and probiotic supplementation in broilers. In contrast to other investigations with MOS, improvements in the BW or gain have been reported (Stanley et al, 2000;Sims et al, 2004).…”

“…Therefore, probiotics (Patterson and Burkholder, 2003) and MOS have the potential to enhance growth rate, feed efficiency, and livability in poultry species (Shane, 1999;Patterson and Burkholder, 2003). On the other hand, some of the reports failed to observe a positive effect of feeding with yeast on growth performance in turkeys (Bradley and Savage, 1995) and broilers (Batista et al, 2007).…”

The effects of dietary hesperidin supplementation on lamb performance and meat characteristics

“…No differences in broilers' DWG, feed intake, final body weight and carcass characteristics were found after flavonoid and mannanoligosaccharide (300 ppm) dietary incorporation (Batista et al . 2007).…”

Phytogenic pigments in animal nutrition: potentials and risks

“…In the paper by Kraemer investigations are listed which show no increase in intake of broilers after addition of flavonoid phytogenics. 30,31 Blank and Wolffram observed an increased feed intake and improved growth rates in weaning pigs fed elder pomace as a known source of polyphenols. 32 This effect was seen as a consequence of an increased palatability of feed.…”

“…However, the simple addition of plant‐derived colorants will not always foster intake. In the paper by Kraemer investigations are listed which show no increase in intake of broilers after addition of flavonoid phytogenics . Blank and Wolffram observed an increased feed intake and improved growth rates in weaning pigs fed elder pomace as a known source of polyphenols .…”
