The Biodegradation Role of Saccharomyces cerevisiae against Harmful Effects of Mycotoxin Contaminated Diets on Broiler Performance, Immunity Status, and Carcass characteristics

Abstract

A feeding trial (35 days) was carried out to investigate the effect of Saccharomyces cerevisiae cell wall as a mycotoxin biodegradation agent on the performance, feed efficiency, carcass traits, and immunity response against diseases in broilers fed aflatoxin B1 contaminated diets. For this purpose, 200 one day old broilers were randomly allotted into four groups, each with five replicates (10 birds per replicate). Four starter and finisher experimental rations were formulated by using (A) 0, (B) 1.25, (C) 2.5, and (D) 3.75 g kg−1 of Saccharomyces cerevisiae. Experimental diets were contaminated with aflatoxin B1 (100 ppb kg−1 diet). The experimental chicks were kept under standard managerial conditions, and the vaccination program was followed against infectious bursal disease (IBD), infectious bronchitis (IB), and Newcastle disease (ND) diseases. At the end of the feeding trial, carcass, organ weight, and blood samples were collected randomly to determine the carcass traits and antibody titer against ND and IBD viruses. Throughout the experiment, the addition of 3.75 g kg−1 of the Saccharomyces cerevisiae cell wall (Group-D) in feed resulted in the highest weight gain, final weight, feed intake, and the lowest FCR values followed by C group compared with the other groups. All carcass traits were significantly (p > 0.05) improved by increasing the inclusion levels of Saccharomyces cerevisiae in broiler diets. It could be concluded that the broiler diet supplemented with 2.5 or 3.75 g kg−1 of Saccharomyces cerevisiae as a biodegrading agent resulted in improved growth performance, immunity activity and carcass traits, and supplementation with Saccharomyces cerevisiae at these levels can be used effectively in broiler diets without negatively affecting bird health status.

Effect of a Diet Supplemented with the Moringa oleifera Seed Powder on the Performance, Egg Quality, and Gene Expression in Japanese Laying Quail under Heat-Stress

“…Previous studies have reported that stress affects the secretion of LH and FSH in turkey poults [40], laying hens [8,41], and turkey hens [42]. Thus, successful and profitable poultry production requires understanding the negative effects of environmental conditions and overcoming them [43,44]. M. oleifera could be used as a valuable feed additive in animal nutrition due to its unique nutritional profile [21].…”

“…Additionally, the seeds of Moringa oleifera are a source of protein, iron, calcium, ascorbic acid vitamin A, and antioxidant compounds, such as carotenoids, flavonoids, vitamin E, and phenolics [46]. The presence of vitamins and minerals benefit the immune system and cure a myriad of diseases [19,43,44,47,48].…”

Effect of Antibiotic, Phytobiotic and Probiotic Supplementation on Growth, Blood Indices and Intestine Health in Broiler Chicks Challenged with Clostridium perfringens

“…The small intestine was measured between the site from which the duodenum emerges from the gizzard and the beginning of the ceca. The relative organ weight was calculated according to Arif et al [42] formula: the relative organ weight = (weight of organ/live weight of bird) × 100.…”

Assessment of Stocking Rate and Housing System on Performance, Carcass Traits, Blood Indices, and Meat Quality of French Pekin Ducks

“…Body weights (BW), weight gain (WG), and feed intake (FI) were recorded at 14 and 49 days of age in early morning before receiving any feed. FCR was also calculated as described by Arif et al [30]. On 49 days, after 12 h of feed deprivation, five birds per group, one bird/replicate/group, were randomly selected, weighed, slaughtered, scalded, wet-plucked, and eviscerated.…”
