Effects of a high dose of microbial phytase and myo-inositol supplementation on growth performance, tibia mineralization, nutrient digestibility, litter moisture content, and foot problems in broiler chickens fed phosphorus-deficient diets

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Different Levels

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.
