morfoanomalías in the sperms of pigs

hello friends wanted to know because you reason sperms they are observed with whip line, drop citoplasmat proximal and distal, line flexionada and is head loose nose talvés related with the extraction form ,falla in the laboratory or problem of the male?

they can be independently all those causes or on the whole. Vos is making reference to a problem that is not unitary, but multifactorial.

Mayra, pleasure in greeting you.
Good, in what I can help, it is that there is a series of factors that you/they influence in the production and the quality of the sperms, I eat for example, age, nutrition, time and frequency of extractions, in short.
When you have a mature age male, not senile, frequently of 2 or 3 weekly extractions, with good health, the spermatic alteration is possibly nutritional, because the reproductive males need a specialized diet, and with different nutritional levels that the feeding of females that is the feeding that is given to the male in general. The levels and the different vitamins and minerals that are needed for the formation of the sperms are those that can be producing an alteration like the one that you mention.
Greetings,

Mayra: He/she receives a greeting from Guadalajara, Mexico.
With regard to your question, the malformaciones of the sperms has different causes:
Infectious: Bacterial for: Leptospira, Erisipela, Estreptococos, Estafilococos, Brucela, and for Virus like: AUJESZKY, PRRS, F.P.C. as the most frequent.
Nutritional for a deficiency of Amino acids: Lisina, Treonina, Valina, mainly and of microminerales as The Zinc, Manganese, Selenium, Vitamins TO, AND and C, basically. And this is generally because I eat habit we feed the reproductive Hogs with portions designed for sows in gestation or sows lactantes. He/she remembers that the Hogs require high levels of sulfurated amino acids and of very good quality. It revises the requirements of PIC for sires, like a nutrition guide for sires.
The illnesses like the Erisipela, F.P.C., PRRS, produces vascular dysfunctions (in the circulation hemática of the testicle). The virus of Aujeszky produces necrosis in the Túbulos seminíferos and in the epididimo, since it affects to the germinal epithelia and of secretion. The other bacterias also produce lesions in the different ones you structure testiculares involved in the maturation and nutrition of the sperms.
The morphology is also affected by a sobretrabajo of the hog, and stiller if it is not well nurtured, although it is well fed.
I wait it is you of utility my comment.

The morfoanomalías of which speak, lines and drops citoplasmáticas, take place in the epidídimo and they are usually cause of estrés situations, as heat, cold, vaccinations,…, or in the event of the drops, besides the estrés, or lack of functionality of the epidídimo or for an inadequate extraction rhythm,…. Therefore, what we should make would be to try to avoid that these estrés situations take place, or to minimize them as much as possible, as well as to make extractions with the appropriate rhythm for the hog in question.

Regarding the sperms without line, again thinking of the simplest thing, the most frequent causes would be the incorrect realization of the tint protocol–extension, or some problem at level testicular that committed the formation of the sperm, that which would be of very bad predicts for the animal, and even cause of their elimination if the problem persists.

A greeting.

Hello. What I can tell you is that you revise the portions in the nutrition topic. You also have to have very in bill the age of the hog, it can be that it is very old or reutilizado and not well fed, he/she remembers that it can be very well fed, but very bad nurtured. This could have relationship in the morfoanomalías of the sperms, or to the case that it could have suffered a blow, and this generates an infection, that which will be seen in the quality of the sperms. Until soon.

Cordial Greeting. These abnormalities are more associated to the part of the espermatogenesis, flaws in the process, immature epz, etc.

Hello. In general it is accepted that an ejaculated normal of pig it possesses from the 1 to the 5 of aberrant sperms, although depending on the race and region in which work, is possible to consider up to a 10 of abnormalities like normal. An ejaculated with more than the 25 of abnormalities it should be discarded, because you will surely have flaws in the fertility. The anomalies can be classified in primary that are those arisen during the espermatogenesis, secondary when we think of those developed by the sperms during their maturation through the itinerary of the epididimo, and lastly the tertiary ones that can be due to the gathering process and extension of the semen. As the colleagues they have already commented, the causes of these malformaciones are multifactoriales, and depending on the problem that you observe, will discard the less decisive options in each case. On the other hand, I recommend you you get a book published by the institute of Catalan studies of the University of Barcelona, published in the 2000, titled spermatic Morphology of the pig, of the doctors Bonet, Briz, Pinart, Sancho, García Gil and Badia, it contains data excellent and excellent pictures obtained after several years of investigation morfológica.

Hello! My experience in handling of semen, allows me, in certain way, to confirm that those problems that you were should to the handling of the semen from the collection. It is probable that the glass collector doesn't have the appropriate temperature, or the glass is without protection to the light, more if the glass is transparent, or when transferring it to the laboratory he/she receives a lot of movement. On the drop citoplasmática, it is very for sure to the interval among collections is very short. I suggest you, observe these factors.

Hello Mayra:
although only work with semen of bovine, in general, the anomalies that are presented have a common origin. For example, the drops proximales or distales indicate a degree of immaturity, the loose heads are very related with the manipulation, and the lines flexionadas, they suggest flaws in the temperature in that you maintain the sperms during the process.
I suggest you that you consult literature about the time of appropriate rest of the hogs, as well as on the vagina temperatures, tube collector, means, etc.
As a presumption, I tell you that it is probable that the hog semen to be less thick, have smaller protection to the abrupt movements that the one of bovine, for what I suggest you that you manipulate it with more softness (for example, when shaking the means in that you receive the semen).
I hope my comments are you of utility. Greetings from Tabasco Mexico.

Hello Mayra,
I think that it would be convenient that above all you control that of anomalies, as they told you. We sometimes find that we find many anomalies to the Microscope, but it turns out to be a low and normal percentage. Of those that named, only one is primary, the drop proximal, the rest can be storage problems (epidídimo) or manipulation, basically.
Gathering the hygienic-sanitary and alimentary conditions in those that those animals are being raised, you could find the cause, if it is that the semen really appears with a high of anomalies.
I hope you count us something more,
Greetings.

Mayra:
I would like you commented me first which the handling of the hog was, from before the extraction, later on, which the handling that you gave to the sample, was and lastly, the form in that you prepared your material and the procedure of evaluation of the seminal sample. Perhaps this is too tedious, but he/she gives me the impression, for your discoveries that you are you speaking of primary and secondary spermatic abnormalities, understanding each other these as those that were generated during the formation process and maturation of the sperms, and of the stage post epididimaria until their exit via ejaculation, respectively.
God willing we had that information, to determine.
Thank you.

Hello Mayra,
I have read several of the answers, and all statement is practically.
But to know the quantity of your particular problem, it is fundamental to have a reference and this is of how many sperms we are speaking, that is to say that of the abnormalities that you mention.
As the other colleagues they say, the causes are very varied, but depending on the anomaly and which their presence is (), you cannot advance a lot. Be possibly something very serious that it impedes you the use of that semen, or they are the normal ones that appear in any ejaculated.
Even some are not so important, as the presence of drop proximal, in most of the cases he/she is due to an use in excess of the males (the sperms don't complete the minimum time in the epididimo like to complete their maderez). Many of the line abnormalities, are due to errors in the tint protocol or to the handling of the semen.
But their we speak of head morfoanormalidades (for e.g.), there the topic is much more complicated because it is a flaw in the espermatogénesis.

Dear Mayra:
The spermatic morfoanomalias, always comes from the hog. They can take place for multitude of factors and they are very frequent in the summer, almost always for some inadequate conditions in the lodging of the animal. A lot of heat, ventilation lack, etc. of course that in the event of fever they also take place. But never for a wrong handling in the laboratory.

Hello friends.
Are we making two extractions for week of the Iberian pigs, not you if something has to also see for the race? And that we are in a time of heat that you sometimes arrives more than 35ºC, but in the place that the reproducers are they have ventilation, and in the moment of the tinsión treatment to make it technically. As you they say, it should be to the caloric estrés and problems of the same pig.

Dear Mayra,
in the experience that I have, I have not detected due differences to the genetics that you/they can explain those abnormalities. For what you count, it is possible that you have a thermal effect, but that depends of which the temperature is in the local where the males are housed, if you are above the 28, care.
But I reiterate you what I commented previously: it is necessary to quantify those morfoanomalías to know in front of what problem we can be.
Greetings.

Hello Mayra,
You really have in this forum the answer to the problem of your hogs, all that written is valid. Clear, the only thing that you should make is to order that commented so that you reach a correct conclusion. It is difficult to give a diagnosis without being present in the place, for it you become the interpreter of all the recommendations and the possible causes of the problem.
I comment you that in the center of swinish Insemination that I have, during 5 years hogs that never overcame the 5 of spermatic pathologies and hogs that always stayed in 8 and 12 have happened. What I want to tell you is that you will always find pathologies, you will never be an ejaculated with 0 of pathologies, that doesn't exist, at least I have not seen them. Therefore you should keep in mind that when a hog overcomes the 15 of pathologies, you are in front of a problem that can be reversible in dependence of the pathology type. But if the one is smaller, then really it IS NOT A PROBLEM. The fertility of having ejaculated with maximum a 10 of pathologies doesn't have significant difference with having ejaculated with smaller percentage, for it the recommendation of using ejaculated that they don't overcome that 10. On the other hand, I recommend you that you analyze at least 1 time per week the spermatic pathologies, you will realize this way that when that of pathologies ascends, you are facing a problem, but when he/she stays, then it is normal whenever it is under the 10. In the registrations you should write down any variation of temperature, handling, feeding, illness, etc. This is good you to determine the possible problems that you can have to future, because when the pathologies are primary, the problem appears 40 days after having been presented the cause, that is to say it IS NOT IMMEDIATE.
I hope these comments are you useful
Chao.

Hello Mayra. Giving for valid all the asseverations of the colleagues, the causes in general are the following ones:

* The whip lines are produced by thermal estrés during the extraction or prosecution of the semen.
* The drops citoplasmáticas are related with the degree of spermatic maturity (immaturity or age), mainly taken place by an inadequate extraction rhythm, also occasionally after vaccinating the hogs.
* The alone heads, they can be caused by a wrong handling of the extención or smear, even with the coloration.
