Problems solved by technology

However, the inventor found that according to the conditions disclosed in this patent, it could not be dissolved when prepared under the condition of 37.5°C water bath. Later, the inventor added 15% ethanol and raised the temperature of the water bath to 42°C. Stir for about 10 minutes to dissolve; secondly, through the inventor's detection with an electronic nose, it is found that this pacifier does not quite match the actual smell of the delivery room, so it has a bad pacifying effect on piglets
In addition, the use of spray in the piglet breeding house will cause the floor or walls to be slippery, which will affect the movement of the piglets or the cleanliness of the house environment. It is difficult to apply it to the skin, and making it into microcapsules will increase the production cost.

Embodiment 1

[0029] The preparation of embodiment 1 piglet pacifier

[0030] Prepare as follows: put capric acid 20g, lauric acid 40g, myristic acid 40g and palmitic acid 100g in a beaker, mix well; then add oleic acid 333mL, linoleic acid 409mL, stir well; then add 187.5 mL of absolute ethanol, and finally put in a water bath at 37.5°C for 10 minutes, and fully stir to form 1000 g of a yellow oily mixture.

Embodiment 2

[0031] The preparation of embodiment 2 piglet pacifiers

[0032] Prepare according to the following method: put capric acid 0.4g (weight percent: 2.0%, the same below), lauric acid 0.8g (4.0%), myristic acid 0.8g (4.0%) and palmitic acid 2g (10.0%) In a 200mL beaker, mix well; then add 6.6mL (30.0%) of oleic acid and 8.2mL (35.0%) of linoleic acid in sequence, and stir well; finally add 3.75mL of absolute ethanol (15.0%); Place in a water bath for 10 minutes, stir well, and form 20 g of a yellow oily mixture. The room temperature condition is 23.5°C.

Embodiment 3

[0033] Embodiment 3 The making of piglet pacifier release box

[0034] according to figure 2 , image 3 The production mold shown is made of plastic, which is molded at one time. The box body 1 is cylindrical, with a height of 5cm and a diameter of 6cm; the height of the box cover 2 is 1cm, and the inner diameter is 6.1cm; 5, the diffuser hole in the center of the box cover 2 is circular, and 4 heart-shaped diffuser holes are symmetrically distributed around it. For the corresponding screw, the two can be screwed together.

[0035]When in use, unscrew the box cover 2, pour the piglet pacifier into the box body 1 of the piglet pacifier release box according to the ratio of 10ml / pig, then screw on the box cover 2, and hang it above the piglet breeding trough 20cm can be.

Abstract

The invention relates to a piglet soothing agent belonging to the field of animal welfare. The piglet soothing agent comprises the following components in percentage by weight: 1.0-3.0% of n-capric acid, 3.0-7.0% of dodecanoic acid, 4.0-8.0% of myristic acid, 8.0-12.0% of hexadecanoic acid, 35.0-40.0% of cis-9,cis-12-octadecadienoic acid, 25.0-30.0% of octadecenoic-cis-9-acid and 15-24% of absolute ethanol. The invention also discloses a preparation method and application of the piglet soothing agent. In addition, the invention also discloses a piglet soothing agent release box which comprises a box body and a box cover, wherein gas scattering pores are formed on the box cover. The piglet soothing agent provided by the invention can significantly reduce the saliva cortisol levels of weaned piglets, slow down the weaning stress of the piglets and obviously reduce the aggressive behavior incidence of the weaned piglets; and in addition, the piglet soothing agent has the advantages of convenient sources of raw materials, no toxicity and harm, no residue and safe and is convenient to use.

Description

technical field [0001] The invention belongs to the field of animal welfare, and in particular relates to a soother for piglets, a preparation method and application of the soother for piglets. Background technique [0002] After weaning, piglets are usually transferred to piglets for cultivation. Due to separation from sows and environmental changes, piglets are prone to psychological stress after weaning, which leads to emotional tension and releases a large amount of stress hormone catecholamines, which affects the health and growth of piglets . In addition, under stress conditions, the animal hypothalamus secretes corticotropin-releasing hormone (CRH), which promotes the anterior pituitary gland to secrete adrenocorticotropic hormone (ACTH), and ACTH promotes the synthesis of glucocorticoids by the adrenal cortex. Cortisol (also known as cortisone or hydrocortisone) is the most important glucocorticoid and can reflect the level of stress in piglets. [0003] Maternal o...
