200 one-day-old Avian chickens were randomly divided into four groups and 0.5%、1%、1.5% "Zeng Mian San"(ZMS) were added in feed of Ⅰ,Ⅱand Ⅲ groups from 7 days old respectively,the IV group was the control.
The results showed that the rates oi pig"s body weight gain and feed utilization were increased by 20. 6% and 17% respectively by adding the biogas slurry (air dry weight) at 1. 5 times as much as the ration, when the ration contained 10% gross protein and digestible energy value of 12. 1 MJ/ kg.
Three hurdred one day healthy broilers were choosed and divided them into ten groups separately,use 0.5%,1%,2% dose of Chinese herbal medicine which compound with Cuzhangsan Ⅰ,Ⅱ,Ⅲ to engage in contrast test of raise broilers,at 1 d,14 d,28 d,56 d survey weight and comsume capacity for feed of broilers of each groups.
In one set of lines animals were fed ad libitum, in the other set they were individually fed a fixed amount of feed (about 10% below the control ad libitum intake) which was not changed over generations.
These results mean that significant amount of feed leachate COD may pass the biological system without any change.
The goal of the inclined conveyor method for particle shape separation is to process a large amount of feed material for recycling technology.
All hatches ate a similar amount of feed to slaughter.
An example of the amount of feed required for various weight ranges is shown in Table 7.
