Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Zinc Levels

An experiment was conducted to investigate the effect of dietary zinc (Zn) level on growth performance, Zn concentration, Zn metalloenzyme activity, Zn transporter 2 (ZnT2) mRNA abundance, metallothionein (MT) mRNA abundance and MT concentration in either serum or tissues, so as to evaluate the optimal dietary Zn level of broiler chicks fed a corn–soybean meal diet from 22 to 42 days of age. At 22 days of age, 288 birds were assigned randomly by bodyweight to one of eight dietary treatments of six replicate cages each with six birds per cage, and fed a Zn-unsupplemented basal corn–soybean meal diet containing 27.66 mg of Zn/kg or the basal diet supplemented with 20, 40, 60, 80, 100, 120 or 140 mg of Zn/kg from reagent-grade ZnSO4·7H2O. Regression analysis was performed to estimate the optimal dietary Zn level in the presence of asymptotic response. The results showed that dietary Zn level had no effect (P > 0.25) on the growth performance, serum alkaline phosphatase and 5′-nucleotidase activities, and liver copper-Zn superoxide dismutase activity, but affected (P < 0.07) tibia Zn concentration, pancreas Zn concentration, ZnT2 mRNA abundance, MT mRNA abundance and MT concentration. The optimal dietary Zn requirements of broilers from 22 to 42 days of age were 62.44 mg/kg for tibia Zn, 64.30 mg/kg for ZnT2 mRNA abundance and 53.50 mg/kg for MT mRNA abundance based on asymptotic models, respectively. Accordingly, the optimal dietary Zn level for broilers from 22 to 42 days of age was 65 mg/kg in this study.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Intestinal Lesion

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

Main Effects

Abstract Four experiments were conducted to determine the effects of increasing soybean meal (SBM) in diets with or without 25% DDGS on growth performance of nursery pigs. Treatments were arranged in a 2 × 3 factorial with main effects of SBM (27.5, 32.5, or 37.5%) and DDGS (0 or 25%). A total of 296, 2,502, 4,118, and 711 pigs, initially 10.6, 11.7, 12.5, and 12.3 kg, were used and there were 10, 16, 13, and 12 replicates per treatment in Exp. 1, 2, 3, and 4, respectively. Experimental diets were fed for 21 d. Pigs were weighed and feed disappearance measured to calculate ADG, ADFI, G:F, and caloric efficiency (CE). Data were analyzed using the GLIMMIX procedure of SAS with block as random effect and treatment as fixed effect. The average cull rate was 0.7, 0.5, 0.2, and 0% and the mortality rate was 0.7, 0.3, 0.4, and 0% in Exp. 1 to 4, respectively. There were interactions (P ≤ 0.039) between SBM and DDGS for G:F and CE in Exp. 2 and for ADG and ADFI in Exp. 3. These were mostly driven by increasing SBM negatively affecting performance in a greater magnitude when diets contained DDGS compared to diets without DDGS. The main effects of DDGS and SBM were more consistent across experiments. Pigs fed diets with 25% DDGS had decreased (P ≤ 0.001) ADG and ADFI in all experiments as well as poorer (P ≤ 0.028) G:F and CE except for Exp. 3. Feeding increasing amounts of SBM generally did not result in any major impact in ADG, but consistently improved (linear, P ≤ 0.078) G:F and CE across experiments. The mechanism for this response is unclear but could be driven by intrinsic components of SBM or underestimating the energy value of SBM.
