Effect of dietary inclusion of fermented sea mustard by‐product on growth performance, blood profiles, and meat quality in broilers

Abstract

BACKGROUND: Sea mustards are traditionally consumed as human food in many Asian countries. However, owing to the large consumption of seaweed, there are a substantial number of by-products produced during processing. These by-products after fermentation can provide a good alternative nutrient source for broilers and serve as a recycled resource reducing the environmental pollution of the seaweed industry. Therefore, an experiment was conducted to evaluate the effect of fermented sea mustard by-product (FSM) supplementation on growth performance, nutrient digestibility, excreta microflora, blood profiles, relative organ weight, and meat quality in broilers. The treatments were: control (CON), basal diet; FSM, CON +2 g kg −1 FSM. RESULTS:During days 1 to 35, with the supplementation of 2 g kg −1 FSM, body weight gain (BWG) increased (P < 0.05), whereas the feed conversion ratio (FCR) decreased (P < 0.05). On day 35, with the supplementation of 2 g kg −1 FSM, excreta Lactobacillus counts increased (P < 0.05), and the excreta Escherichia coli counts decreased (P < 0.05). There were no significant effects (P > 0.05) on nutrient digestibility, blood profile, relative organ weight, and breast meat quality of broilers fed with FSM diets. CONCLUSION: Dietary supplementation of 2 g kg −1 FSM can improve growth performance, and shifted excreta microflora by increasing the proliferation of Lactobacillus counts and by decreasing E. coli counts.

Supplemental Impact of Marine Red Seaweed (Halymenia palmata) on the Growth Performance, Total Tract Nutrient Digestibility, Blood Profiles, Intestine Histomorphology, Meat Quality, Fecal Gas Emission, and Microbial Counts in Broilers

“…Regarding terms of feed development in broiler production, the focus has expanded to include potential supplementation with natural products. Based on our results, the inclusion of seaweed in a corn/soybean meal-based diet led to significant increases in weight gain and feed efficiency, similar to the findings of Shi et al [ 28 ]. Evans and Critchley [ 9 ] also showed that the dietary inclusion of seaweed enhanced bird health and productivity and improved the gut microflora.…”

The effects of dietary seaweed inclusion on growth performance of broiler chickens: a systematic review and meta-analysis

“…A total of 2,257 broiler chickens were involved in this study. The seaweed type used included seaweed blend 27 , Laminaria japonica 28,30 , Undaria pinnatifida 29,31 , Hizikia fusiformis 31 , and Ulva lactuca 32 . The inclusion dose ranged from 2 to 30 g/kg, while the intervention duration ranged from 21 to 42 days.…”

Effects of dietary seaweed supplementation on milk productivity, milk quality and health of dairy cows

“…In recent years, seaweed (known as marine algae or marine macroalgae) has been interested in applied scientific fields, especially in nutritional composition and its benefits in the health improvement of humans and animals (Brown et al, 2014;Shi et al, 2019;Shimazu et al, 2019). In fact, it is very rich in several polysaccharides and complex carbohydrates (Makkar et al, 2016); or in useful metabolites and necessary minerals, being considered as a natural source of additives in various animals (Morais et al, 2020).…”
