good Moment of it mounts it or of the insemination.
Do they agree you that the good moment to inseminate or to mount a sow is when the inmobilidad reflection is presented in the female?

The moment of the Insemination should be determined since according to the female type that you are inseminating, it is not the same thing a female lecturer, one miscarried, or a primeriza, or mainly a weaned female (that even varies a lot according to the day that he/she enters in zeal after the weaning). The important thing is that the Insemination you of in an appropriate moment so that the sperms are available in the fecundation place to the moment that the ova are also, for what it is necessary to also take into account the life useful or functional point of sperms and ova. For what cannot be considered the reflection of immobility like the good moment to inseminate the females, because you should also take into account how many times you are detecting zeal a day, and the type and quality of detection of zeal that you are carrying out in your females.
Greetings.

Andrés,
What specific symptom of behavior does it indicate me that should inseminate or don't unite sow?
The sows, depending on their state: if it is mature, primeriza, lecturer and if it has miscarried, does it vary me the duration of the zeal? It is what I have understood.
Do you think that a corporal state under it should influence in inseminating a sow or not?
Rather, should I inseminate the thin sows that show me symptoms of zeal, or is it better to recover them to be served?
A very special greeting,

Andrés S

Andrés Looks:
The females, depending on their type (miscarried, repeated, primeriza or weaned), it varies the duration of zeal, being very unstable and I cut in the first 3 types, and where it is longer it is in the weaned females, mainly those that present zeal after 3 to 5 days of the weaning, for what you should value each female to know when to inseminate the female starting from that it presents the Reflection of Immobility (also depending if you detect heat twice or one a day). The corporal condition of the females is indispensable to value it, and it is also necessary to consider that you can measure the Thickness of Dorsal Fat (EGD), besides the visual qualification of the condition, to be more sure of the condition of the females, because of it depends it the productivity of the female, in certain cases it is very advisable allowing to pass the zeal in very thin females, and to recover them and to inseminate them until the following zeal.
Greetings.

Andrés, thank you for your answers.
Is the thickness of dorsal fat measured in mm to the height of the first lumbar vertebras, until what does he/she mediate in mm it indicates me that I should or not to inseminate or to serve a sow of low corporal condition, rather, what do you limit they exist?
The races and could genetic lines also be an indicative one of if to inseminate them or not?
Do you believe that that influences?
Greetings.

Not you if it is the appropriate forum, but he would want some suggestion for the sows that still in zeal they resist to it mounts it of the spear, I have had to discard them as reproductoras. Is there some suggestion?
Thank you.

Andrés, although your question is of the month of July, I wait that same it serves you.
The mensuration of EGD, in alive animals, is carried out in the denominated point P2 (that belongs together with the 10 and 11 rib). The mensuration of EGD, is used to estimate the energy reservations that he/she has a female. In primerizas, although there is variation with the genetic type, it is recommended not to mount them or to inseminate them before the 7 months, and with a superior weight to the 130 kg (this in EGD means 18-20 mm in P2).
To see the corporal condition, you can also use something similar to what is used in bovine livestock, where the whole female is appreciated. If they interest you more details, we see like we make.
I agree with the comments that he/she made you Andrés with relationship to the moment of the IA, but if it is mature females (that already gave birth to), in moment that the zeal appears after the weaning, he/she has effect on the duration of the zeal, and therefore moment of making the insemination.
Greetings,

the reflection of the inamovilidad of the sow is Generally the sign that we need to know if we should inseminate or to make the it mounts. The dilemma is in synchronizing this cubrición according to the status of the animal (substitutions, multíparas, miscarried, etc) since, like they described previously, the duration of the zeal varies before according to the status mentioned and it is impredesible the maximum point of the ovulation (or I itch of the ovulation curve). In the farm where I work we use conventional artificial insemination and we synchronize in the following way:
Substitutions: they cover to the moment to present the inamovilidad reflection due to the short duration of the zeal and later on each 12 Hr until completing three cibriciones. That is to say, Hour 0, 12, 24.
Female multiparas: Dejasmos to pass the moment of the reflection and we inseminate the 12, 24 and 36 Hrs. That is to say, if it leaves in the morning in zeal, we inseminate in the afternoon, tomorrow of the following day and in the afternoon. If it is in the afternoon, we inseminate in the morning of the following day, the afternoon and the morning of the third day.
Lecturers: He/she is carried out it mounts natural to the moment of the repetition and the 24 Hrs. We only accept a repetition, if the female repeats for second time, automatically we discard it, unless one has to consider the productivity of the same one.
Miscarried: We don't serve them, we discard them.
We use this system since chequeamos I guard in the morning and in the afternoon and the average of having been born totals is of 11 pigs for childbirth.

In the service, be this it mounts natural or IA, what is looked for is that to the moment of the ovulation they are the sperms qualified in the fecundation place.
Regarding the ovulation this usually happens in the 2/3 of zeal (the problem is that we don't know when the zeal lasted) and it is simultaneous, that is to say the entirety of the ova is ovulated in a period of 2h.
With relationship to which it is the good moment to make the it mounts or IA, depends on several factors:
1 - form of detection of the zeal, if one makes with presence of the male one and twice a day, you can usually detect the zeal at their beginning, if one makes without the male (for the alone man) this it is not detected in all the females (more difficult in nulíparas) and the detection is achieved at least 12 hours after initiate the zeal.
2 - in nulíparas (also llamandas reinstatements or cachorras) this hard one less 36 to 48 h.
3 - in multíparas (mature) it depends on the moment of appearance of the zeal after the weaning, today in day there are works demonstrating that if the zeal appears until the 4° day it is longer than if he/she appears from now on of the 5 day.

There are protocols but detailed (if to some he/she is interested him I can send it) but I eat general recommendation and if we make detection of zeal with the male:
to) in the first case it is recommended to make the first insemination at the 24 hours of detectrado the zeal,
b) in the second case at the 12 hours,
c) for the nulíparas it is recommended to make the insemination to the moment to detect the zeal,
d) for lecturers at the 12 hours of having detected.
After the first one it is recommended to make inseminations every 12 hours, while the sow allows it (that is to say it is in zeal).

According to my experience, it would not spend time in the sows that miscarry since they usually have sequels and in their majority they have reproductive problems again.

The good moment to inseminate or to give mounts, it is the second day that the zeal is presented, because it is when the ovulation is presented in that lapse of time, besides detecting very well the days in that the estro stage begins, and to identify the proestro stage perfectly.

It is notorious when a sow presents the clear signs of zeal, it is restless, vulva swelling (intense pink color), it mounts other sows, etc. All producer should be alert to these signs.

Although we should be careful the silent jealousies that you/they are jealousies that you/they allow to spend, and it is an economic loss each zeal that spends in the farm.
