Description

Fermented compound traditional Chinese medicine additive for improving water content and PSY of sows and sheep and preparation method thereof
Technical Field
The invention belongs to the technical field of feed additives, and in particular relates to a fermented compound traditional Chinese medicine additive for improving the water content and PSY of sows and sheep and a preparation method thereof.
Background
Sow labor refers to the time it takes a sow to expel all the fetus from the body to the outside of the body at the time of delivery. In actual production, the time required for normal delivery of the sow (labor) was on average 4 hours (calculated as delivery of 12 piglets), and the average delivery interval between the two piglets was 20 minutes. However, in our investigation, it was found that the phenomenon of too long a sow in the pig farm (especially in summer) is very common, with a labor time of up to 5-8 hours, and even a fraction of sows up to 24-48 hours.
A series of hazards can be generated when the sow is in too long a labor course: firstly, the harm to sows is that the sows are extremely easy to generate delivery syndrome (extremely tired, severe pain and metabolic disturbance) after delivery, the delivery syndrome is manifested by poor postpartum mental state caused by excessive physical energy consumption, birth canal bleeding and vaginal household edema, and even death caused by vaginal and uterine prolapse or uterine rupture and massive hemorrhage; the sow has the advantages of no postpartum fever, difficult appetite recovery, lochia inexhaustibility, postpartum infection and the like, has high incidence rate of endometritis, greatly prolongs the recovery time of the normal function of uterus, and does not have oestrus for a long time after weaning; affecting the recovery of the normal appetite of the sow, resulting in the milk deficiency of the sow. Secondly, the harm to piglets is that the sow has too long a labor, and the longer the fetus is extruded in the uterus and the birth canal. Each time of uterine contraction and knoop can cause temporary interruption of blood supply of the fetus, long-time uterine contraction and knoop can cause persistent hypoxia of the fetus, and the intrauterine embarrassment and asphyxia of the fetus are caused, so that the weaned pigs and the shaggy pigs are obviously increased, death occurs in the delivery process, and the death rate is increased. Weak piglets tend to have poor vitality after birth, enough colostrum is not eaten, enough maternal protection can not be obtained, the conditions of diarrhea and yellow-white dysentery in lactation are increased, and the survival rate is low.
There are many reasons for the too long labor of sows, of which hypoamniotic fluid is one of the most important reasons. Amniotic fluid refers to a fluid filled around a fetus during gestation and surrounded by amniotic membrane (see FIG. 1), which consists essentially of placental permeate, fetal alveolar fluid and fetal urine [ Setnikar, et al, the fetalus lung, a source of amniotic fluid, proc Soc Exp Biol Med 1959, 101:842-845; brace, et al Regulation of amniotic fluid volume: insights derived from amniotic fluid volume function cultures.Am J Physiol Regul Integr Comp Physiol.2018,315:R777-R789. When amniotic fluid is excessive, normal water balance can be maintained by swallowing and intra-amniotic absorption of the fetus [ bell, et al regulation of amniotic fluid volume Plamenta, 2008, 28:824-832; brace, et al Regulation of amniotic fluid volume: insights derived from amniotic fluid volume function cultures.Am J Physiol Regul Integr Comp Physiol.2018,315:R777-R789. Normal amniotic fluid volume in the amniotic cavity may provide protection for fetal movement, growth and health [ Dubil and mangen. Ambaritic fluid as a vital sign for fetal wellbearing. Australias J Ultrasound med.2013,16 (2): 62-70 ]. Fetal swallowing of amniotic fluid helps reduce the incidence of necrotic enteritis in newborn piglets [ Good, et al, ampholytic fluid attenuates experimental murine and piglet necrotizing enterocolitis via reduced TLR signaling, gastroenterology,2013,144 (5): S314-S314 ] ], whereas fetal swallowing of amniotic fluid is almost zero when the amount of amniotic fluid is well below normal [ brain, et al, fatal swallowing as a protective mechanism against oligohydramnios and polyhydramnios in late gestation light, reprod sci.2013,20 (3): 326-330 ] ], and therefore, maintaining normal amniotic fluid is very important for fetal health and development. The lack of amniotic fluid can increase the mortality of fetuses and newborns, and can also obstruct the growth of fetuses, so that the fetuses are underdeveloped, pulmonary diseases are very easy to occur after the fetuses are born, and even the neonates die. Insufficient amniotic fluid during delivery may make the fetus difficult to break the amniotic membrane, prolonging the delivery time [ thibult, et al, neonaal pulmonary hypoplasia with premature rupture of fetal membranes and oligohydrammos.J Pediatr.1985, 107:273-277; kitterman, et al, effects of oligohydramnios on lung growth and maturation in the fetal at the rate of Am J Physiol Lung Cell Mol physiol 2002,282:L431-L439 ], in addition, because the amniotic fluid contains a large amount of organic matters, when the amniotic fluid is too little, the amniotic fluid in the amniotic cavity becomes viscous, the too little amniotic fluid and the relatively high viscosity thereof cause the increase of resistance of the birth canal, the piglets cannot be rapidly discharged from the birth canal, the hypoxia in the birth canal is caused, and the hypoxia can cause the serious reduction of the vigor of the primary piglets or the choking death in the birth canal of a fetus, so that the number of the produced and alive piglets of the sow is reduced. Studies have shown that the amniotic fluid in each amniotic cavity in a sow slowly increases from an average of 1.7 ml at 30 days of pregnancy to 201.3 ml at 85 days, then decreases to 107.4 ml at 105 days, and then approximately 26.3 ml of amniotic fluid at 112 days [ Goldstein, et al, hybridization of changes in volume, osmolarity and electrolyte composition of porcine fetal fluids during gel station. Biol reprod.1980,22 (5): 1168-1180 ].
In the middle and late gestation period, amniotic fluid volume mainly depends on urine excretion and alveolar fluid secretion of a fetus, proline in fetal urine is the most important amino acid required for fetal lung maturation, and insufficient proline content is likely to cause fetal lung hypoplasia when amniotic fluid is too low [ Harman. Amniotic fluids abominable chemicals. Semin Perinant.2008, 32:288-294; wu, et al Pulmonary Hypoplasia Induced by Oligohydramnios: findings from Animal Models and a Population-Based student, pedia Neonatl.2017, 58:3-7; weiner, et al, amniotic fluid volume at presentation with early preterm prelabor rupture of membranes and association with severe neonatal respiratory mobility, ultrasonic bond Obstet Gynecol.2019,54:767-773 ] is prone to respiratory disease after birth and even causes death of the neonate due to respiratory abnormalities [ Tanahashi, et al, polyhydroamnios in Lrp4 knockout mice with bilateral kidney agenesis: defects in the pathways of amniotic fluid clearance.Sci Rep.2016,6:20241 ]. In the middle and late gestation, the fetus can ingest nutrients, active factors and precursors of synthetic antibacterial substances by swallowing amniotic fluid, thereby promoting its own growth and intestinal maturation [ Li, et al, permeation in the biochemical composition of fetal fluids are apparent in surviving bovine somatic cell nuclear transfer pregnancies in the first half of station. Biol reprod.2005,73 (1): 139-148.; buddington, et al, prenatal gastrointestinal development in the pig and responses after preterm birth.J Anim Sci.2012; 90:290-298; wu, et al biological mechanisms for nutritional regulation of maternal health and fetal development, paediatr Perinat epidemic 2012;26:4-26.]. Amniotic fluid plays a more remarkable role in the last stage of pregnancy as a nutritional pathway of the fetus, and if this pathway is blocked, it leads to retarded intrauterine growth of the fetus (intrauterine growth retardation, IUGR) [ Wang, et al, tempororal proteomic analysis reveals defects in small-intestinal development of porcine fetuses with intrauterine growth, restriction.j Nutr biochem.2014,25 (7): 785-795 ].
In a large-scale pig farm, in order to pursue a large primary weight, the sow is subjected to fetal tapping in the later period of pregnancy, namely, the feeding amount and the nutrition concentration of the pregnant sow are increased, so that the nutrition substances such as protein and the like fed by the pregnant sow far exceed the normal requirement. In addition, the sow feed often contains mycotoxin, and long-term ingestion of the feed can cause accumulation of mycotoxin in a body, so that cardiovascular and fetal lung and urinary organs of the sow are damaged, and the blood supply of the sow to the fetus is insufficient, and the fetal alveolar fluid and urine are formed insufficiently.
How to increase the amount of amniotic fluid in the antenatal sow is a urgent problem to be solved in the current pig farm production, because sufficient amniotic fluid can enable the sow birth canal to be smooth during delivery, the formed water sac has the functions of softening and expanding the cervix and the birth canal of the parent, so that the fetus can be conveniently and smoothly produced, and the harm of dystocia to the sow and the piglet can be greatly reduced; in addition, sufficient amniotic fluid can inhibit bacteria to reduce birth canal infection.
Uterine-vaginal-mastitis can reduce the annual average weaned pig count (PSY) of a Sow, because long-term uterine vaginitis of the Sow can easily cause weak implantation of fertilized eggs, so that symptoms such as increased embryonic death, blocked intrauterine development of a fetus or Sow oestrus return occur, and the like, while mastitis can easily cause the milk yield and quality of the lactating Sow to be reduced, and the survival rate of the lactating pig is reduced. Studies show that sows are susceptible to uterine vaginitis and diarrhea in piglets after infection with escherichia coli, staphylococcus aureus, salmonella and streptococcus.
At present, there are reports of using traditional Chinese medicine feed additives to shorten sow labor, but the reports of the documents do not relate to the traditional Chinese medicine feed additives to shorten sow labor, which is related to the increase of sow amniotic fluid, and also do not relate to the increase of possible effective components and potential mechanisms of the sow amniotic fluid in the traditional Chinese medicine feed additives.

7 elucidating the mechanism of increasing amniotic fluid by certain Chinese medicinal components
Reducing inflammation in sows, protecting organs and blood vessels, increasing blood flow and membrane permeability are important ways to increase fetal urine and alveolar fluid production. The data in Table 2 show that the fermented compound traditional Chinese medicine feed additive contains a plurality of medicinal components with the effects of resisting oxidation, resisting bacteria, diminishing inflammation, protecting cardiovascular diseases, accelerating blood circulation and increasing vascular permeability. Ellagic acid, gallic acid, methyl gallate, ethyl gallate and kaempferide have effects of resisting oxidation and reducing injury, and can keep the morphological structure of heart, lung, kidney and blood vessel intact, and exert physiological function to the maximum extent; 7-hydroxycoumarin has diuretic effect; 7, 8-dihydroxyflavone and ellagic acid have the effects of dilating blood vessel, and increasing vascular permeability and blood flow; kaempferol, caffeic acid and salidroside have protective effect on normal development of fetal pulmonary artery blood vessel, thereby ensuring normal blood supply of lung; protocatechuic aldehyde has the functions of protecting internal organs, promoting microcirculation and dilating blood vessels; genistein has the effect of protecting glomerulus; kaempferol can alleviate nephritis and repair kidney injury. These pharmacodynamic components allow more blood to flow into the capillaries of the alveolar and glomerular surfaces, thereby producing more alveolar fluid and urine (see figure 3). Therefore, under the synergistic effect of the medicinal components, the average amniotic fluid quantity in the amniotic cavity of the pregnant sow of the test group is obviously higher than that of the control group. The moderate increase of the sheep water quantity can not only reduce the viscosity of the amniotic fluid, but also ensure that the birth canal is fully kept in a lubrication state, so that the piglets can be rapidly discharged outside the body through the birth canal under normal conditions, and the birth interval is shortened.
8 elucidate the antibacterial and anti-inflammatory effects of certain Chinese medicinal components
Studies have shown that the compounds in table 2 have various degrees of antibacterial and anti-inflammatory effects. Wherein, ellagic acid has stronger inhibition effect on staphylococcus aureus, salmonella, escherichia coli, streptococcus and bacillus cereus; purine and amino acid can inhibit the growth and reproduction of bacteria in bacteria by forming a riboswitch, thereby achieving the antibacterial and bactericidal effects; camphor inhibits salmonella growth and rejects animal endotoxin; pyrogallic acid and demethylwedelolactone have the function of inhibiting staphylococcus aureus, escherichia coli and salmonella; kaempferin, gallic acid and quercetin have good antibacterial effects on staphylococcus aureus, escherichia coli, bacillus dysenteriae, pseudomonas aeruginosa and streptococcus; the ethyl gallate can inhibit the growth of staphylococcus aureus; eriodictyol and inositol have good inhibition effects on escherichia coli, staphylococcus aureus and pseudomonas aeruginosa; the dihydroxyflavone, asiatic acid and the microorganisms such as shigella dysenteriae, salmonella, streptococcus, staphylococcus aureus, escherichia coli and the like of the isomouse Li Sudui all have good inhibiting or killing effects. The plant active ingredients play a role in bacteriostasis and sterilization mainly through the ways of inhibiting the generation of Extracellular Polymers (EPS), reducing the adhesion of bacteria, destroying the integrity and permeability of bacterial membranes, inhibiting the activity of enzymes in bacteria, changing the metabolism of cells, inhibiting the synthesis of nucleic acid, enhancing the immunity of animal bodies and the like.
