The effect of varying levels of high- and low-tannin faba bean (<i>Vicia faba</i> L.) seeds on gastrointestinal function and growth performance in turkeys

The effect of the dietary inclusion of pea seeds of colored-flowered and white-flowered varieties on gastrointestinal function in turkeys

“…This is an important consideration in the interpretation of the results of the present experiment where rapeseed was used as an energy component in the same amount in all diets. In the remaining treatments, digesta viscosity did not exceed 3 mPa⋅s, which is comparable with the values noted in experiments where SBM was partially replaced with faba beans ( Przywitowski et al., 2017 ; Mikulski et al., 2017 ) or peas ( Zduńczyk et al., 2020 ). The results of similar studies indicate that the viscosity of small intestinal digesta in the range of 2 to 3 mPa⋅s can be treated as a normal physiological state of the intestines in turkeys, at which the antinutritional effect is not observed ( Jankowski et al., 2013 ).…”

Gastrointestinal response to the early administration of antimicrobial agents in growing turkeys infected with Escherichia coli

“…In the present experiment, the experimental factors were not diet-related and the diets did not contain anti-nutritional components. This does not change the fact that the health status of the ceca, including enzyme activity and microbial metabolite profile, is of paramount importance in the production of premium-quality poultry products ( Przywitowski et al, 2017 ). Therefore, this study focused on intestinal processes that are often disregarded by researchers analyzing the growth performance and productivity of birds.…”

“…Their results can be used to determine the role played by the microbial community in intestinal metabolism. Therefore, attempts were made in previous studies to analyze the content and profile of bacterial fermentation end-products (ammonia, SCFAs) as well as the activity of selected bacterial enzymes in the large intestinal digesta, in the latter case instead of bacterial counts ( Zduńczyk et al, 2014 ; Przywitowski et al, 2017 ). According to Cuccato et al (2022) , antibiotics can compromise the intestinal health of broilers by increasing intestinal permeability, promoting inflammatory responses, and damaging the intestinal epithelium.…”

Valorization of faba bean (Vicia faba) by-products

“…However, feed conversion was lower in the groups fed with seeds low in tannin content than in the groups fed with high tannin seeds. The authors state that tannin-containing seeds can be mixed into the feed up to 30% (w/w) without negative effects [153]. Furthermore, Trevino et al confirmed in their studies that the weight of the chickens, the feed intake, and feed efficiency were reduced by adding tannins to the feed [154].…”
