Effects of microencapsulated Lactobacillus rhamnosus JCM 1136 probiotics on blood parameters and body composition of rainbow trout

Effects of the microencapsulated Lactobacillus rhamnosus JCM 1136 on the blood parameters and body composition of rainbow trout (Oncorhynchus mykiss). In this study, first the probiotic bacteria L. rhamnosus JCM1136 were microencapsulated with coatings of sodium alginate and chitosan. Then, they were added to the food pellets and given to the fingerlings. For this purpose, 225 rainbow trout fingerlings (6.23 ± 0.17 g) in 5 treatments and each treatment with 3 replications were placed in California trays (220 × 30 × 15 cm). Treatment 1 (T1): Fish fed with 108 CFU/g microencapsulated probiotics with sodium alginate, treatment 2 (T2): fish fed with 108 CFU/g microencapsulated probiotics with sodium alginate and chitosan, treatment 3 (T3): fish fed with 108 CFU/g capsule-free probiotics, treatment 4 (T4): fish fed with probiotic-free sodium alginate-chitosan capsules and control treatment 5 (T5): fish fed with commercial free-probiotic and capsules pellets. At the end of the course, results indicated that the fishes fed with diet containing sodium alginate-chitosan microencapsulated probiotics in terms of blood parameters such as red blood cells, white blood cells, hemoglobin and hematocrit as well as the amount of carcass protein compared to control and other treatments were in better condition, which These differences were significant with control treatments fishes (p < 0.05)

Effects of prebiotic (Fermacto) in low protein diet on some blood parameters and intestinal microbiota of broiler chicks

This study was conducted to evaluate the effects of prebiotic (Fermacto) in low protein diet on serum cholesterol and intestinal microbiota of broiler chicks. One hundred and fifty six 1-day old Ross 308 broiler chicks of both sexes were used for 42 days. The chicks were randomly allocated to 12 pens containing 13 chicks each with 3 replicates and assigned to receive one of the 4 dietary treatments of 2 levels of protein (low and high) and 2 levels of prebiotic (0 and 0.2%) in a completely randomised design with factorial arrangement. There were no significant differences in serum HDL and LDL levels among treatments. Significant differences were observed in serum cholesterol and intestinal microflora between the high protein diet without prebiotic and the low protein diet containing prebiotic (P<0.05). The results of the present experiment showed that the addition of prebiotic to broiler diets containing 90% of the NRC protein recommendation significantly affects serum cholesterol and intestinal microflora of broiler chicks (P<0.05)
