Test example 1
In vitro inhibition of African swine fever virus
The African swine fever virus-resistant swine powder of examples 1-4 containing 0.3%, 0.5%, 0.7% and 0.9% formic acid ratios and the commercial plain powder (control group) containing no formic acid were co-cultured with African swine fever virus for 24 hours, and the time points for observing the survival rate of African swine fever virus were 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 5 hours, 12 hours and 24 hours, respectively.
The results of the test are shown in fig. 1, and the toilet powder of formic acid at all concentrations continuously decreased the survival rate of african swine fever virus with time. While the control group had no effect on the survival of African swine fever virus. The survival rate of african swine fever virus of 0.5% formate group, 0.7% formate group and 0.9% formate group was significantly lower than that of 0.3% formate group. In general, the survival rates of the African swine fever viruses of the 0.5% formate group, the 0.7% formate group and the 0.9% formate group were successively lower as the concentration of formate increased from 2h to 24h of the culture.
Test example 2
Animal testing
In 2019, 3 months, a certain pig farm in Guangdong, to-be-born sows are divided into three groups, and 180 newborn piglets and 90 sows are subjected to comparative tests respectively, wherein 1 group is a control group (no talcum powder for pigs is used); group 2 is prepared by applying the refreshing powder for pigs, which is used for resisting the African swine fever virus in the embodiment 1 of the invention, to the whole bodies of the born piglets; the 3 groups are commercial talcum powder with better effect, and the talcum powder is also smeared on the whole body of the born piglet. Each group had 60 piglets and 30 sows. After use, the contrast test is used for observing the hair color brightness, mental state, excretion state, respiratory state, survival rate, umbilical cord dropping time, healing condition, sow vulva healing and the like (the incidence of endometritis is used as a measurement index). Comparative observations are shown in table 1.
TABLE 1
As can be seen from Table 1, compared with the control group, the fur of the piglets in the groups 2 and 3 is more regular, the drying speed of the body surfaces of the piglets is faster, and the umbilical cord shedding time and the umbilical cord healing time of the piglets in the groups 2 and 3 are shorter than those in the control group. And the average daily gain of piglets and the survival rate of piglets are higher in the experiment 2 group and the experiment 3 group than in the control group. The groups 2 and 3 were lower than the control group in the incidence of diarrhea in piglets and the incidence of endometritis in sows.
According to the test results, the pig talcum powder for resisting the African swine fever virus can effectively dry the furs of the born piglets, improve the production performance of the piglets, reduce the reproductive diseases of postpartum sows and provide a barrier for the pigs to defend the African swine fever virus.
