The purpose of this experiment is to investigate the application efficacy of stress Ning on the production performance of commercial broiler chickens. 1280 healthy 1-day-old AA broiler chickens with similar body weight were selected and randomly divided into 4 treatments, with 8 replicates per treatment and 40 chickens per replicate (see Table 1).

In order to study PQQ The efficacy of Na2 in improving the immune and antioxidant properties of commercial broiler chickens. 1440 healthy 1-day-old AA broiler chickens with similar body weight were selected and randomly divided into 6 treatments, with 6 replicates per treatment and 40 chickens per replicate (see Table 1). Treatment 1: Control group, fed with a corn soybean meal based basic diet; Processing 2, 3, 4, and 5, the control group was supplemented with PQQ on the same diet basis Na2 0.1,0.2,0.3,0.4 mg/kg； Treatment 6: The control group was supplemented with PQQ on the basis of the same diet Na2 (chemical synthesis) 0.2mg/kg. The experiment is divided into two stages (0-21d, 22-42d).

The purpose of this experiment is to investigate PQQ The application effect of Na2 on the production performance of commercial broiler chickens. 1440 healthy 1-day-old AA broiler chickens with similar body weight were selected and randomly divided into 6 treatments, with 6 replicates per treatment and 40 chickens per replicate (see Table 1).

On November 25, 2020, Zhu Baoku, Secretary of the Party Committee of the School of Animal Science and Technology at Shandong Agricultural University, Professor Yang Zaibin, Professor Yang Weiren, Associate Professor Jiang Shuzhen, and Li Zhaoyong, Chairman of SD BIOTECH GROUP, and their delegation went to Shandong Huayu Group, Dongying Blue Ocean Group, Zibo Hefeng Seed Industry Technology Co., Ltd. and other enterprises to carry out a two-day industry university research exchange.

SD BIOTECH GROUP, as a major technology innovation project in Shandong Province, has achieved significant breakthroughs in the efficient production of high-quality livestock products through the transformation of technology achievements and high-quality livestock product production technology combination solutions. It has also cooperated with multiple enterprises.

Yanning improves feed efficiency and weight gain by significantly reducing three targets: feed induced immune response, high digestibility, and enteritis control, resulting in a comprehensive economic benefit increase of about 3%. The mission of Yanning is to control a series of inflammations such as enteritis, salpingitis, endometritis, mastitis, glandular gastritis, pericarditis, peritonitis, etc., which cause a decrease in production performance. At the same time, the excessive defense response of the body to inflammatory factors results in significant feed waste.

Professor Yang Zaibin, Chief Designer of Technology Innovation at SD BIOTECH GROUP, completed the "Illustrated Livestock and Poultry Standardization Scale Breeding Series Series" project, which won the second prize of National Science and Technology Progress Award.

The evaluation meeting for the achievements of major scientific and technological innovation projects in Shandong Province was successfully held. Two achievements jointly developed by SD BIOTECH GROUP and Shandong Agricultural University, namely "Research and Application of Key Technologies for Functional Premixtures and High Quality Eggs in Egg Chickens" and "Research and Application of Key Technologies for Octagonal Feed Utilization", were appraised by experts and received unanimous recognition and praise. Both achievements have reached the "international advanced level". The four major series of 13 products, mainly Yanning, of Shengdao Biotechnology Group have been widely promoted and applied in the market, adding benefits to feed enterprises and bringing profits to many breeding enterprises.

In order to study the improvement of broiler production performance by enzymatic hydrolysis of polysaccharides and Boluohui. This study selected 960 healthy 1-day-old AA broiler chickens with similar body weight and randomly divided them into 4 treatments, with 12 replicates in each treatment and 20 replicates in each replicate (see Table 1). The experiment used a 2 × 2 factorial method: treatment with 2 extracts of Platycodon grandiflorus (0 mg/kg vs. 300 mg/kg); Two yeast hydrolysate treatments (0 mg/kg vs. 75 mg/kg).
