Description

Dipping piglet talcum powder preparation and preparation method thereof

Technical Field

The invention relates to the technical field of animal husbandry, in particular to a piglet talcum powder preparation for dipping of newborn piglets and a preparation method thereof.

Background

With the development of breeding technology, the pig raising industry in China gradually develops to intensification, the breeding management of large-scale pig farms is more and more standardized, the number of newborn piglets continuously rises every year, and the production performance is continuously improved. However, a considerable part of pig farms have the problem of bad environment, such as poor air circulation caused by unreasonable animal house design, one place for feeding and discharging, substandard temperature control conditions and the like. These conditions are all likely to cause diseases such as cold, diarrhea and the like of piglets, thereby affecting the healthy growth of the piglets.

Survival of piglets depends on a number of factors, of which birth is a very important influencing factor. Since the farrowing of sows is random and the farrowing of many sows occurs at night, if the delivery work is not in place, the survival rate is likely to be reduced. When the piglets are born, the bodies of the piglets are wrapped by the fetal membranes and mucus, if the piglets cannot be wiped clean in time, the piglets can be suffocated by the mucus in the oral cavity, and if the mucus on the bodies cannot be cleaned in time, the cold air in the environment can quickly take away the heat of the piglets, so that the piglets have diseases such as diarrhea and the like, the growth and the metabolism of the piglets are not facilitated, and the phenomena of slow growth and the like are caused; therefore, the development of the talcum powder is very important, and the talcum powder can improve the survival rate of piglets, guarantee the health of sows, reduce economic loss and improve production benefits.

The common pig talcum powder on the market at present has a plurality of problems. Firstly, the pH value is alkaline (pH: 9-11), and the skin of the newborn piglet is stimulated to a certain extent; secondly, the application method is mostly manual smearing, the operation is troublesome, the consumed time is long, the interval time from the first end to the last end is long, the phenomenon of uneven smearing is easily caused due to the waste of the talcum powder and the low utilization rate, the time interval from birth to the contact of part of piglets with the colostrum is prolonged, and the vitality is reduced. Finally, the traditional talcum powder has no functions of disinfecting and keeping the body temperature of piglets, and each kilogram of talcum powder can treat a small number of piglets, so that the cost is high, and the input-output ratio is low.

The piglet talcum powder preparation is acidic, has no stimulation, has the functions of quick drying, heat preservation and disinfection on newborn piglets, is small in dosage of each piglet, can be dipped for use, and is very little in waste.

The application method of the piglet talcum powder preparation capable of being dipped for use comprises the following steps: the steps are as follows: (1) the piglet talcum powder preparation is placed in a barrel and then sealed, and is forcibly shaken up and down to be changed into loose fluid; (2) as shown in fig. 2, the neck or head of the piglet is grasped, and the tail part is downwards vertically dipped in the preparation in the barrel; (3) the dipped piglets are shown in figure 3 and are placed on the nipples of sows; (4) after a plurality of piglets are dipped, the dry powder can be shaken upwards from the bottom of the container for a plurality of times by properly using two hands, so that the dry powder is changed into a fluid state again and then is used continuously.

The product characteristics of the present invention compared to prior art piglet talcum powders and prior art talcum powders for piglets are shown in table 1.

TABLE 1

To further highlight the characteristics of the piglet talcum powder preparation of the invention, comparative studies were performed in the laboratory. Unless otherwise specifically stated, the mixtures of silica and silicate used in the following examples and comparative examples were first heat-treated at 380 ℃ for 2 hours and then at 1100 ℃ for 3 hours. Wherein the purity of the tricalcium phosphate, the calcium sulfate, the magnesium sulfate, the ferric oxide, the copper sulfate, the kaolin powder and the talcum powder is more than 98 percent.

The components and the contents (wt%) of the piglet talcum powder formulations of the examples and comparative examples are shown in table 2.

TABLE 2

In comparative example 4, the mixture of silica and silicate was not heat-treated.

The sample powders of the piglet talcum powder preparations prepared in the above examples 1 to 6 and comparative examples 1 to 6 were placed in a constant temperature oven with a temperature of 30 ℃ and a relative humidity of 90% for 48 hours, and then the angle of repose of the sample powders was measured by a fixed cone bottom method to evaluate the fluidity of the sample powders. The method comprises the steps of firstly preparing a disc flat bottom with edges and a funnel, enabling sample powder to flow from the bottom of the funnel to the disc flat bottom (operation, the height from the funnel to a powder cone top is kept at 2-4 cm), carefully adjusting the height of the cone to obtain a powder cone with good symmetry, and then calculating the angle of repose. The angle of repose satisfies the following relationship: tan θ ═ cone height (h)/disc radius (r). The results obtained are shown in Table 3.

TABLE 3

Experiments show that the liquid crystal gel prepared in the embodiment 1-6 can keep proper fluidity after being placed for 48 hours, is suitable for dipping, and shows good drying and heat preservation effects; the powders of comparative examples 1, 3 and 4 to 5 had poor flowability and looseness, and the dipping resulted in non-uniformity, and the amount was large, and the drying effect was remarkably deteriorated. While comparative examples 2 and 6 had good fluidity, the dipping operation was much more likely to cause peeling, and the actual drying effect was not good.
