Butyrate and propionate improve the growth performance ofLitopenaeus vannamei

Abstract

Organic salts may improvement the animal performance, increasing the efficiency of nutrient utilization and modifying the intestinal microbiota. This study aimed to evaluate the effects of sodium butyrate and sodium propionate supplementation at different levels of dietary inclusions in the growth of Litopenaeus vannamei. In total, seven diets were evaluated: a control diet (without supplementation) and three diets from each sodium salt, propionate and butyrate, in concentrations of 0.5%, 1% and 2%. We used 21 tanks of 6000 L stocked with 150 shrimps (2.53 AE 0.03 g). The shrimps fed diets supplemented with propionate and butyrate, in all concentrations, increased their final weight. The feed efficiency, nitrogen retention, protein efficiency rate, survival and yield of shrimps fed the diet containing 2% butyrate were higher in comparison with control treatment. The shrimps supplemented with butyrate also showed lower counts of Vibrio sp. in the intestine. The shrimps fed the diet supplemented with butyrate and propionate also showed higher values of serum agglutination titre. Thus, it is possible to conclude that dietary supplementation with propionate and butyrate in different dietary concentrations modify the intestinal microbiota and improves the growth of L. vannamei.

Dietary Supplementation with Butyrate and Polyhydroxybutyrate on the Performance of Pacific White Shrimp in Biofloc Systems

“…In another study of shrimp reared in clear water, Silva et al () observed that a diet supplemented with sodium butyrate increased the growth and survival of L . vannamei .…”

“…In the clear‐water rearing of L . vannamei , dietary supplementation with 0.5 and 2% of sodium butyrate increased the retention of nitrogen and the rate of protein efficiency, but phosphorus was not retained (Silva et al ).…”

“…Some authors have demonstrated sodium butyrate as a potential in vitro inhibitor of pathogenic bacterial strains in fish and shrimp (Nuez‐Ortin ; Silva et al ). In clear water, shrimp fed with sodium butyrate (0.5–2%) also had lower values of Vibrios ; however, no significant differences were observed for total heterotrophic marine bacteria (Silva et al ). The potential for inhibition induced by butyric acid, mainly against Gram‐negative bacteria, results from organic acid passing through the cell membrane in undissociated form and then dissociating in the cytoplasm.…”

“…Moreover, these authors observed an improvement in performance of L . vannamei cultured in an indoor clearwater system with dietary supplementation of 0.5–2% of sodium butyrate (Silva et al ).…”

Effect of dietary L-malic acid supplementation on growth, feed utilization and digestive function of juvenile GIFT tilapiaOreochromis niloticus(Linnaeus, 1758)

“…Organic acids or their salts are capable of inhibiting the growth of harmful intestinal microorganisms such as coliforms, enterococci and vibrio sp. (Øverland et al., ; Zhou et al., ; Silva et al., ) and promoting the reproduction of acid tolerant beneficial bacteria such as Lactobacilli (Luckstadt, ), which may ultimately increase the digestive enzyme activities of the fish intestine (Askarian et al., ).…”
