Effects of dietary supplemental bile acids on performance, carcass characteristics, serum lipid metabolites and intestinal enzyme activities of broiler chickens

Abstract

The objective of the present study was to evaluate the effect of bile acids derived from swine on the growth performance, carcass traits, serum lipid metabolites and intestinal enzyme activities in broiler chickens. Four hundred thirty-two 1-day-old Arbor Acres male broilers were randomly assigned to 4 treatments with 6 replicates of 18 chicks each for 42 d. The experimental treatments received a corn-soybean basal diet containing lard and were as follows: 0 (control), 40 mg, 60 mg, and 80 mg bile acids/kg of diet. Dietary of inclusion bile acids significantly increased average daily gain and decreased feed to gain ratio from d 21 to d 42 (P < 0.01). However, average daily feed intake was unaffected by dietary supplementation with bile acids. The dressing percentage and the percentage of thigh muscle in the carcass were notably (P < 0.01) higher for broilers fed diets supplemented with 60 and 80 mg/kg bile acids. In contrast, abdominal fat weight was reduced significantly (P < 0.01). In 42-day-old broilers, serum triglyceride, high density lipoprotein and low density lipoprotein concentrations were unaffected (P > 0.05) by bile acids supplementation. Supplementation with 60 and 80 mg/kg significantly increased the activity of duodenum lipase and lipoprotein lipase on d 21 and d 42, as well as decreased the activity of hormone sensitive lipase on d 42. Supplementation of diets with 60 and 80 mg/kg of bile acid can effectively enhance the activity of intestinal lipase and lipoprotein lipase and improve growth performance and carcass traits of broilers.

Effects of Bile Acids and Lipase Supplementation in Low-Energy Diets on Growth Performance, Fat Digestibility and Meat Quality in Broiler Chickens

“…Similar results were also reported by Zhao and Kim (2017) and Hosseini et al (2018) who observed that TG, TC, HDL-C and LDL-C concentrations were unaffected due to dietary energy in broilers. In the present study, bile acids supplementation in LE diet did not change serum TG, TC, HDL-C and LDL-C, which is in agreement with (Alzawqari et al, 2011;Ge et al, 2018;Lai et al, 2018b). Similarly, lipase supplementation along with bile in LE diet had similar effect as bile acid supplementation alone in LE diet.…”

“…Supplementation of bile acids in broiler diet significantly improve the digestibility of fat (Nazir, 2014;Hemati Matin et al, 2016;Lammasak et al, 2019). Similarly, other studies (Ge et al, 2018;Lai et al, 2018a;Lai et al, 2018b) reported that the supplementation of bile acids improve daily weight gain, feed conversion ratio (FCR) and carcass yield in broilers.…”

Impact of dietary supplemental bile salts on growth performance, carcass, immunity and antioxidant parameters and bacteriology of broiler chicks

“…These results agreed with the observation obtained by Alzawqari et al (2016) and Lai et al (2018) who indicated that BWG improving significantly in broiler chicks fed diet plus bile acid matched with the nontreated group. However, Rezaeipour et al (2016) indicated that bile salts preparation failed to take out any increased significantly in broiler chick's performance (LBW and BWG).…”

Association of predicted deleterious single nucleotide polymorphisms with carcass traits in meat-type chickens

“…When bile acids are released in the ileum, induces the synthesis of fibroblast growth factor (FGF-19) which stimulates hepatic protein and glycogen synthesis (Kir et al 2011). In an interesting work in broilers, Lai et al (2018) demonstrated that dietary supplementation of swine bile acids for broiler chickens influences their growth performance and carcass characteristics as reduction of abdominal fat, As presented above the genes BARL, WDR77 and VWA8 were selected as candidate genes for muscle growth and development in chickens. SYCP1, CRNN, CRY4 were not selected as candidate genes for muscle growth or carcass development in this study, because there is no information available in the literature to support this.…”
