Effect of Feed Additive Supplementation on Growth Performance, Intestinal Morphology, Intestinal Microflora and Nutrient Digestibility Study of Broiler Chicken

Abstract Phytogenic feed additives have become attractive alternatives for use in animal diets. The objective of the present study was to evaluate the effect of a phytogenic-based feed additive on growth performance, nutrient digestibility, blood profiles, fecal noxious gas emission, and intestinal morphology of weaning pigs after dietary challenge with E. coli K88. A total of 120 crossbred pigs [(Yorkshire × Landrace) × Duroc)] with an initial body weight (BW) of 6.09 ± 0.96 kg (21 d of age) were assigned randomly to 1 of the 4 dietary treatments. Each pen housed 5 pigs, and there were 6 pens/treatment. Treatments included: T1, negative control (without antibiotics); T2, T1 + antibiotic; T3, T1 + 0.05% phytogenics; and T4, T1 + 0.2% commercial mix of organic acids. Overall, the average daily gain (ADG) with the T3 treatment was higher (P<0.05). At wk 1, the apparent total tract digestibility (ATTD) of dry matter (DM) was increased (P<0.05) with T4 treatment. The ATTD of ash with T3 and T4 treatments was greater (P<0.05). At wk 3, pigs fed with the T4 diet had a significantly higher (P<0.05) ATTD of DM. The ATTD of ash and calcium (Ca) was significantly increased (P<0.05) with the T4 treatment. Pigs fed with the T3 diet had a higher (P<0.05) ATTD of phosphorus (P). At wk 6, the ATTD of ash was significantly increased (P<0.05) with the T1 and T3 treatments. The data indicate that phytogenics positively affect growth performance of weaning pigs, indicating that their use as an alternative in the diets of weaning pigs can significantly improve ADG, under challenge with E.coli K88.

Abstract The objective was to determine the functional and nutritional values of Corynebacterium glutamicum Cell Mass (CGCM) on growth performance and gut health of newly-weaned pigs. Forty newly-weaned pigs (21 d of age; initial BW 7.1 ± 0.4 kg) were allotted to 5 dietary treatments based on randomized complete block design with sex and BW as blocks. The lysine broth of CGCM (CJ Bio, Fort Dodge, IA) was homogenized by using French press and dried to obtain lysed CGCM. Dietary treatments were: basal diet with lysed CGCM at 0, 0.7, 1.4, 2.1%, and with 1.4% intact CGCM. Experimental diets were formulated based on nutrient requirements (NRC, 2012) and pigs were fed based on 2 phases (10 and 11 d for each phase). Titanium dioxide (0.4%) was added to phase 2 diets as an indigestible external marker to calculate nutrient digestibility. Feed intake and BW were measured at d 0, 10, and 21. Pigs were euthanized on d 21 to collect proximal and distal jejunal mucosa to measure TNF-α, IL-8, MDA, IgA, and IgG concentrations. Diets and ileal digesta were collected to measure AID. Data were analyzed by SAS using MIXED, REG, and GLM procedures. Overall, increasing daily lysed CGCM intake increased (P < 0.05) ADG (211 to 296 g) and ADFI (432 to 501 g). Increasing levels of lysed CGCM decreased (P < 0.05) MDA and changed (quadratic, P < 0.05) IgA (max: 4.90 ng/mg at 1.13%) and IgG (max: 3.37 ng/mg at 1.04%) in the proximal jejunal mucosa. Increasing daily lysed CGCM intake had quadratic effect (P< 0.05) of protein carbonyl (max: 6.3 μmol/mg at 4.9 g/d). Lysed CGCM potentially benefits growth performance and gut health of newly-weaned pigs by reducing oxidative stress and increasing immune response.

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.

Daily Gain

The present study investigated the effects of dietary supplementation of a seaweed extract (SWE) to sows and weaned pigs on post-weaning growth performance, intestinal morphology, intestinal microflora, volatile fatty acid concentrations and immune status of pigs at days 11 and 117 post-weaning. Gestating sows (n20) were supplemented with a SWE (0v.10·0 g/d) from day 107 of gestation until weaning (day 26). At weaning, pigs (four pigs per sow) were divided into two groups based on sow diet during lactation and supplemented with a SWE (0v.2·8 g/kg diet), resulting in four treatment groups: (1) BB (basal sows–basal pigs); (2) BS (basal sows–treated pigs); (3) SB (treated sows–basal pigs); (4) SS (treated sows–treated pigs). Pigs weaned from SWE-supplemented sows had a higher average daily gain (ADG) between days 0 and 21 (P < 0·05) post-weaning compared with pigs weaned from non-SWE-supplemented sows. Pigs offered post-weaning diets (PW) containing SWE had decreased colonicEscherichia colipopulations on day 11 (P < 0·01) and decreased colonic Enterobacteriaceae numbers on day 117 (P < 0·05). Pigs offered PW containing SWE had a greater mRNA abundance ofMUC2in the colon at day 11 post-weaning (P < 0·05) compared with pigs offered unsupplemented diets. In conclusion, these results demonstrate that SWE supplementation post-weaning provides a dietary means to improve gut health and to enhance growth performance in starter pigs. Dietary SWE supplementation increased ADG during the grower–finisher (GF) phases. However, there was no growth response to SWE inclusion in GF diets when pigs were weaned from SWE-supplemented sows.

Abstract The aim of this trial was to determine the optimal supplementation mealworm on growth performance, apparent total tract retention of nutrients, hematological traits, immune response, and intestinal morphology in weaned pigs. A total of 180 weaned pigs (Landrace×Yorkshire×Duroc; 6.27 ± 0.15 kg) were randomly allotted to 3 treatments and 6 replicates on the basis of initial body weight and sex. The dietary treatments included a corn-based diet supplemented with 0, 2.5, or 5 % mealworm in 2 phases (0–14 and 15–28 d). The gain to feed ratio (G:F) was higher in pigs fed 2.5% mealworm compared with 2.5% during the first phase. Overall ADG was improved in pigs fed 2.5% mealworm compared with pigs fed 5% mealworm. No improvement in overall ADFI and G:F were observed. No digestibility responses were observed by adding mealworm to the diet, but the digestibility of DM and GE were tended to be higher in pigs fed 2.5% mealworm compared with control in phase 1. The number of monocytes tended to be increased in pigs fed 5% mealworm. The concentration of plasma IgG was higher in pigs fed mealworm, however, the plasma IL-6 was tended to be decreased when mealworm was added to the diet (P = 0.052). There was no change in intestinal morphology with increasing dietary levels of mealworm. The results showed that the dietary supplementation of 2.5% mealworm had beneficial effects on growth performance and immune system, however, no effects were detected on growth performance when 5% mealworm was added to the diet.
