Ma Youxiang: Three experiences of grain saving and consumption reduction in China's aquaculture industry

At the recent video conference on the promotion of soybean meal reduction and substitution action, Ma Youxiang, vice minister of agriculture and rural affairs, emphasized the great significance of this deployment, summarized relevant work experience, and pointed out some existing problems
.

He said that in recent years, China has focused on improving efficiency and saving grain, open source substitution, reducing the amount of soybean meal on the demand side, increasing the supply of alternative resources on the supply side, and taking multiple measures to achieve initial results
.

01 Adhere to the efficiency of food saving, and vigorously promote low-protein diet technology
.

Practice has proved that by adding and using industrial synthetic amino acids in the feed to make up for the short board nutrients in the raw materials, the amount of protein in the feed can be effectively reduced and the waste can
be reduced.
If additives such as enzymes are used at the same time, the digestion and utilization rate of
feed protein can also be greatly improved.
The low-protein diet is called low-protein and is actually of high quality
.
"Judging from the effect of promotion in the past two years, there is still a lot of work to be done
about low-protein diet technology.
" Ma Youxiang said

On the one hand, there is room for further downward adjustment in the amount of soybean meal used, and soybean meal accounts for an average of 11.
8% of the feed produced by 33 million-ton feed enterprises across the country, which is 3.
5 percentage points
lower than the industry average.
On the other hand, China's amino acid industry is at the world's leading level, with the ability to produce all animal essential amino acids, production and export volume are in the forefront of the world, and most of the product prices have dropped to the acceptable level of feed breeding enterprises, providing a strong guarantee
for expanding the scope of application of low-protein diet technology.

02Adhere to open source and save grain, and fully tap the potential
of new feed protein resources.

Ma Youxiang believes that while promoting the reduction of traditional feed proteins such as soybean meal, some unconventional new protein feed resources also have great potential
.
For example, in recent years, the Ministry of Agriculture and Rural Affairs has launched the pilot project of the use of feed for surplus food at the table, and the pilot cities have been expanded to 10
.
"It turns out that we banned the so-called kitchen residue as feed in the prevention and control of African swine fever, but after a certain degree of processing, it is no problem, but it is a very important source
of protein.

It also mentioned that the Ministry of Agriculture and Rural Affairs has carried out pilot projects for the feed utilization of fur animal carcasses in Hebei and Liaoning; The first new feed ingredient certificate was issued to the manufacturer of Clostridium ethanol protein and successfully achieved factory mass production

Ma Youxiang pointed out that from the perspective of tapping potential, animal carcasses and alternative resources such as concentrated slaughtered animal blood, leftover food on the table, microbial bacterial proteins, and urea have great development and utilization value
.
After these resources are processed and processed in a standardized manner, they can be used as feed protein under the premise of ensuring safety, and together with the protein raw materials for soybean oil expansion and production, the supply of feed protein can be increased by more than
10 million tons.

03 Adhere to increasing grass and saving grain, and ensure the supply
of forage for cattle and sheep.

Practice shows that compared with the current structure of high amount of refined feed and low amount of high-quality forage, each additional kilogram of high-quality forage can reduce 1.
2 kilograms of refined feed, which can play a role
in replacing grain with grass and increasing grass and saving grain.
At the same time, the comprehensive efficiency of forage planting is higher, and planting high-quality forage such as alfalfa and silage corn can produce 100 kg of forage protein per mu of arable land, which is twice as
much as planting grain and oil crops.
If the alfalfa corn set crop model is adopted, the average yield of forage protein can reach 160 kg per
mu.

Ma Youxiang said that if the forage structure of cattle and sheep is optimized, scientific and accurate feeding, and the same amount of beef and mutton is produced as in 2021, it is estimated that the consumption of refined feed can be reduced by nearly 24 million tons

He also said that the primary problem that needs to be solved urgently at present is that the ideological understanding is not in place, "to some extent, it is a small technical problem and a big problem
in understanding.
" "For example, some places believe that cultivated land can only grow grain, not grass, but in fact, the requirements of the three types of cultivated land (high-standard farmland, permanent basic farmland and general cultivated land) are not the same, and grass is not allowed to be planted without a one-size-fits-all approach
