AbstractA 42-d study was conducted to investigate the effects of an emulsifier supplementation (de-oiled soyabean lecithin (DSL)) of diets with different levels of metabolisable energy (ME) and various sources of fat on growth performance, nutrient digestibility, blood profile and jejunal morphology of broiler chickens. Diets were arranged factorially (2 × 2 × 2) and consisted of two concentrations of ME (normal and low), two fat sources (soyabean oil (SO) and poultry fat (PF)) and two levels of DSL supplementation (0 and 1 g/kg). A total of 800 1-d-old male broiler chickens were assigned to eight treatments with five replicates/treatment. The results showed the supplemental DSL caused improvements in the overall feed conversion ratio, fat digestibility and jejunal villus height:crypt depth ratio, but the magnitude of the responses was greater in the PF-containing diets, resulting in significant fat × DSL interactions (P<0·05). Abdominal fat percentage was also reduced by the PF-containing diet, but the response was greater in the normal ME diet, resulting in a significant ME × fat interaction (P = 0·048). Dietary DSL supplementation also increased nitrogen-corrected apparent ME values but decreased blood TAG (P = 0·041) and LDL (P = 0·049) concentrations, regardless of the source of fat used or the ME values in the diet. In conclusion, the present study suggests that the improvements in growth performance, fat digestibility and intestinal morphology that can be achieved with DSL supplementation are highly dependent on the degree of saturation of lipid incorporated into broiler chicken diets.

Abstract This study aimed to determine supplemental effects of phytase (VTR BIO-TECH, China) on bone parameters, jejunal mucosa-associated microbiota, intestinal morphology, nutrient digestibility, and growth performance of broiler chickens (Ross 308). Newly hatched broiler chickens (360, 44 ± 6 g BW) were randomly allotted in 6 treatments with 10 birds per cage based on CRD and fed for 27 d. Dietary treatments were the supplementation levels of phytase providing (0; 500; 1,000; 2,000; 4,000 FTU/kg feed) and 0.15% less Ca and 0.15% less P than the recommended requirements by ROSS 2019. Titanium dioxide (0.4%) was added to the diets as an indigestible marker to measure AID. On d 27, 3 birds were randomly selected from each cage and euthanized to collect jejunal mucosa and tissue to measure microbiota diversity and morphology, ileal digesta to measure AID, and left tibia to measure bone parameters. Data were analyzed using SAS. Phytase supplementation tended to increase overall ADG (P = 0.078; 39.7 to 42.2 g/d), whereas without affecting the overall ADFI and G:F. Phytase supplementation reduced (P &lt; 0.05) Pelomonas (10.01 to 2.64%) and tended to reduce Helicobacter (P = 0.085; 10.67 to 0.88%); Pseudomonas (P = 0.090; 2.02 to 0.31%); Sphingomonas (P = 0.071; 1.03 to 0.19%). Phytase supplementation increased (P &lt; 0.05) villus height (884 to 989 µm); the AID of CP (65.4 to 70.6%) and P (36.3 to 43.7%). Increasing phytase supplementation from 0 to 1,296 FTU/kg increased (P &lt; 0.05) breaking strength (184 to 213 N) and P content in the tibia (9.5 to 10.0%). In conclusion, phytase supplementation up to 4,000 FTU/kg feed showed benefits on intestinal health by reducing harmful bacteria in the jejunal mucosa, enhancing intestinal morphology and by increasing the AID of nutrients; and on the bone parameters by increasing the breaking strength and P content.
