Description

A compound feed for growing and finishing pigs with reduced ammonia concentration in pig houses

technical field

The invention belongs to the field of livestock and poultry breeding, specifically relates to animal nutrition and feed, in particular to a compound feed for growing and finishing pigs which reduces the ammonia concentration in pig houses.

Background technique

With the rapid development of animal husbandry and the improvement of breeding intensification, while animal husbandry provides humans with meat, milk, eggs and other livestock products, the accompanying odor of livestock and poultry manure is also harmful to the growth of pigs and the environment. cause serious harm. This not only destroys the normal ecological balance, endangers human beings, consumes protein feed resources excessively, but also seriously restricts the sustainable and stable development of the animal breeding industry.

Pig house odor (ammonia) comes from microbial decomposition of residual nitrogen-containing substances in manure. To reduce the odor (ammonia) in the pig house, we should first use modern nutrition principles to reduce the residual amount of nitrogen-containing substances in pig manure by reducing the protein content in the feed; Balanced additives to maintain the health of the body and high utilization efficiency of nitrogen-containing substances, thereby reducing the residual nitrogen-containing substances in pig manure; secondly, using microbial ammonia-reducing agents that can use themselves and biologically fix nitrogen inside and outside pigs Further reduce the residual amount of nitrogenous substances in manure and inhibit its decomposition to produce ammonia. On this basis, the main measures to reduce the odor of pig houses are to remove the feces and urine in the pig house in time, to maintain the sanitation of the pig house and to maintain a good ventilation state. At present, the reduction of ammonia concentration in pig houses through nutritional regulation is in the research stage, and there is no finalized product in China. It is innovative and necessary to develop and research compound feeds that reduce the ammonia concentration in pig houses.

The present invention will be described below based on the experimental results.

As test subjects, 90 Du×Chang×Da Sanyuan hybrid growth-finishing pigs with a body weight of about 34 kg were selected. They were randomly divided into two groups, the control group and the test group, with 3 repetitions in each group and 15 heads in each repetition. The control group was fed with the full-price compound feed produced by the local Hebei Dexing Feed Co., Ltd., and the test group was fed with the ecological compound feed of the present invention.

The test was carried out at Xuguang Pig Farm in Wei County from April 1st to June 1st, 2013. The indicators measured in the test were:

(1) On the 1st day at the beginning of the test and the 60th day at the end, weigh the two groups of pigs on an empty stomach respectively, and calculate the weight gain of each group;

(2) record the number of dead heads of each group every day, and calculate the death rate of each group during the test;

(3) Record the material consumption of each group every day, and calculate the material-to-weight ratio;

(4) At 9:00 and 16:00 every day, the concentration of ammonia and CO ₂ in the house was detected with the mini warnb portable multi-gas detector produced by Germany's Del Company.

All the following test data are processed by SPSS13.0 software, and the processing results are compared by LSD method or Duncan method to see if the difference is significant.

Test result 1: The effect of compound feed on pig growth performance is shown in the table below

It can be seen from the test results in the above table that the average daily weight gain of the pigs in the test group increased by 52.50g compared with the control group, and the feed-to-weight ratio was also 0.31 lower than that of the control group. The difference was significant (P<0.05), which improved the pig growth rate and feed Conversion rate.

Test result 2: The effect of compound feed on the odor in the pig house is shown in the table below

It can be seen from the test results in the above table that the ammonia concentration (mg/m3) and _CO2 (mg/m3) in the piggery of the test group were significantly lower than the control group, and the difference was significant (P<0.05) compared with the test group. ). The survival rate of the pigs in the test group was 100%, and no death occurred, while the death rate of the pigs in the control group was 1, and the survival rate was lower than that of the test group. It can be seen that the compound feed for growing and finishing pigs with reduced ammonia concentration in the pig house of the invention has a good growth-promoting effect, which is reflected in three aspects: increasing the growth rate of pigs, improving the feed conversion rate, and reducing the mortality rate.

The present invention adheres to the principle of "prevention first, and prevention is more important than cure" in solving the problem of animal husbandry's environmental pollution, uses ecological principles, and uses modern nutrition regulation methods to reduce the ammonia concentration in pig houses from the root, and promote Livestock and poultry health, saving protein feed resources, reducing production costs, so as to achieve efficient, ecological, sustainable and healthy development of pig farming.
