Animal Feed Yeast-Yeast culture manufacturers
Purpose of the experiment:
To determine the effect of adding animal feed yeast to broiler diets on broiler production performance
Experimental location:
Tashan broiler farm of Fuxi Group
Experimental time:
September 28, 2020-November 10, 2020
Farming mode:
Free-range on the ground
Experimental design:
This experiment selected 120,000 one-day-old commercial broilers (Kebao) in two greenhouses and divided them into a control group and an experimental group. The control group had 60,000 chickens in one greenhouse and the experimental group had 60,000 chickens in one greenhouse. The entire experimental period was divided into two stages, broilers (birth-21 days old) and broilers (21 days old-43 days old). The experimental group broilers were added with 0.3% animal feed yeast as the basic diet, and broilers were added with 0.2% animal feed yeast. The control group was the basic diet. The experimental group used an experimental diet in which animal feed yeast replaced soybean meal and oil in the basic diet.
Experimental method
The basic diet used in the experiment was self-supplied by the Fuxi Group Feed Factory. The control group and the experimental group were given exactly the same basic diet, feeding management system and environmental conditions. In the experimental group, 0.3% of Yidakang was added to the broiler formula in the feed factory to replace 4KG fat and 5KG soybean meal in the basic diet, and 0.2% of Yidakang was added to the broiler formula to replace 2KG fat and 2KG soybean meal in the basic diet. The chickens were weighed when entering and leaving the chickens, and the feed input was accurately recorded every day in the greenhouse unit, and the daily weight gain, daily feed intake, and feed-to-meat ratio were calculated. The mental state of the chickens was observed at any time.
Effects on the production performance of broiler chickens
| Group | Initial weight(g) | Final weight(g) | Daily weight gain (g) | Daily feed intake (g) | Feed to meat ratio |
| Control group | 45 | 910 | 41.2 | 48 | 1.17 |
| Animal Feed Yeast Group | 45 | 938 | 42.5 | 45 | 1.06 |
| Difference | 0 | 28 | 1.3 | -3 | -0.11 |
Effects on the production performance of medium and large chickens
| Group | Initial weight(g) | Final weight(g) | Daily weight gain (g) | Daily feed intake (g) | Feed to meat ratio |
| Control group | 910 | 2900 | 90.5 | 158.4 | 1.75 |
| 938Animal Feed Yeast Group | 938 | 3000 | 93.7 | 157.5 | 1.68 |
| Difference | 28 | 100 | 3.2 | -0.9 | -0.07 |
Notes:
1. Body weight, daily weight gain, and daily feed intake are averages.
2. This experimental data is limited to free-range farming.
Experimental conclusion:
Adding 0.3% animal feed yeast to the broiler formula to replace 4KG fat and 5KG soybean meal in the basic diet can reduce the feed-to-meat ratio and increase daily weight gain. Adding 0.2% animal feed yeast to broiler chickens to replace 2KG fat and 2KG soybean meal in the basic diet can also reduce the feed-to-meat ratio and increase daily weight gain.
