t seems to avoid the contact with other tigers to be a credo of this Panthera - although otherwise the neighbors have a good circumstance. It is union time to observe almost retain the single aberration of this during that During this short time the sexes tolerate themselves and remain together it on a relatively narrow field.

After L. G. Kaplanovs observations the "partners" live together so narrow, that they leave a lot of making a track while wandering and the appearance of a whole "tiger flock" results. This mistake lower ran however honor inexperienced persons. The propagation itself mostly comes about at a period of three to eight days and occur several times per day. It however, was observations deviating strongly from these information already made. As extreme values for the length the union period can one for the minimum three days and the maximum twenty-three days may specify. Per day, then about ten (very much little) occur until eighteen splice grafts. In order to complete the information still control one state that every splice graft approximately can last ten seconds to three minutes. However, the immissio itself only lasts few seconds (2 - 6 seconds).

Approximately 5-7ml Ejakulat becomes free in the case of every immissio, in the case of a correlation (p > 0,05) between ejakulat and testicle volume of approx. 75cm3. The tigersperm is for instance 5,8µm long and 3,95µm broad. Measurements also yielded that sperms are in every ejakulat-sample around the 175,4 x 106 motile. This is essential more than for example with the cheetahs with 30,45 x 106 case you even moreer information on this subject require then send you me one emial via the link at the bottom of page.

For usual the tigress is on the ground with the stomach and the tiger is above her. A special feature in the case of this course of events is the neck bite with that of the tigers firm his companion adheres. This is the second addressed already and honor ritual, importance of the boat bite next to tigers. It is not for somebody that familiar to this behavior looks this with safety according to a killing experiment more als after a love game from. Subsequent can you see the coarse process:


A. the oestric tigress approaches the tiger (1). both ones first contact contact mistrustfully and cautiously (2). the tigress approaches for the tiger, moustache
hair to moustache hair and they ”kissing" (3). the tigress ”offers herself".

B. With position during splice graft (4). the tigress raises her backside a little in order to facilitate mounting the tiger (5-9). Tiger and tigress begin to roar, the sounds during the union ring as ”Ar Ar Ar Ar. . .". On the climax of the union bite the tiger firm into the neck of the tigress and ejects a penetrating scream. As soon as the union is carried out, the tigress throws the tiger off (10), a short fight then follows and they part. The entire union sequence lasts between 10 sec and 3 mins. cool after splice graft itself one OR both in the water off; they are then page to page. The tigress after a short time gets up and stage 3 or 4 is repeated the whole for itself off. the union indemnifies ten to eighteen once on the day of 3-23 days over a period instead of. [from K. S. Sankhala 1967]

 

Very frequent can observed dramatic atmosphere variation of the tigresses during the union may be. One of a calmer tiger and an extremely irritable tigress can speak generally. In the action is sometimes it the case that the tigress abrades her head gentle at that of her partner in a moment and abrades it completely non-mediated in the nearest one it and not provoked with the paws after it hits and/or zu bite. That bursts suddenly a tigress directly after the union act open and hits according to her partner can one also recognize in a repeated manner. These strokes however, are not that what one would understand as gentle. One would be able to even take them (the strokes) as brutal since tigers were seen at their flanks beautifully more often with bleeding claw lanes after the union act. For this reason, one mostly very much ensures in zoological gardens that the tiger has enough place in order to be able to jump at the side after the union act fast. That it is the tiger has interest in the union more in future no one to be observed very often if the tiger should be hurt this not the case be and by it it and this mostly for the rest of her life.

Former factories went out from the monogamy of the tiger. Testify contemporary finding however clip and of course polygamy the tiger next to the lion which is case, similarly how this. Ought it during union readiness (oestrus) not come for an impregnation, in such a way, the heat of the tigress inserts on the average after six to nine weeks again. These however, information can differ, there this both from the tiger lower kind, the individual and other factors off change. The expert opinions on this subject are similarly different.

As last, I would like to deal with the question when tiger and/or tigress become sex ripe. On this subject, very information very different from a lot in part exists. The variation ready one is not in percent very large among the different sub-kinds, the most misunderstanding result from the many different means the scientist that having gathered these information. Tiger masculine for the existing freely ones (all the same which sub-kind) control one an old man of 1/2 years of plus minus an 1/2 year specifying. For tigresses, one can also indicate 3 years plus minus a 1/2 year - consequently, they are sex ripe a little in former times as the males. On average, all tigers and tigresses those exist in captivity are sex ripe sooner a year cousins existing as yours in freedom.

Although there is very often quarrel among the scientists via state of the propagation cycle, it is nevertheless regarded as so good today as certainly, that the tiger (tigress!!) at general information full-year polyoestic - want to be called, that it over it can come in a distributed manner all year for union acts and pregnancies. The distribution of the birth number follows in a seen manner a Gauss'schen normal distribution coarsly and February culminates in the months by April. Consequently control one the "winter months" indicate October by December as main union time (independent of the respective hemisphere) - here therefore, can one relatively many unions observe if one would like thatdouble-exclamation

Some researchers would test too other connections like humidity, temperature and lighting conditions in the purchase also the oestrus the tigers. A connection between humidity and oestrus-duration and/or occurrence could not be found. However, connections could not of course be shot out at the temperature (particularly not next to the sibirian tiger). it seems to however be a connection between brightness and oestrus. In an experiment, a tigress of brightness unchangeable over a half year day and night (as on the day) was abandoned. Your sisters held under normal brightness circumstances showed no modification in the oestrus-behaviour, lasting those isolated tigers approx. three weeks sooner into the oestrus came. For this reason, the photoperiodicness of the oestrus of the tigress was formulated.

In zoological gardens, one is mostly troubled to find out the date of union readiness precisely. However, one can only gain relatively inaccurate information by means of urine and the sampling and a possible blood withdrawal regular through would be be led much too extensive. For this reason, one keeps to five mostly secure signs. The so-called lordotic bend the loin area roll over the back and wrap itself abrade the flanks and the forehead on the cage walls and/or. -pole as soon as roaring groaning are mostly such secure signs. The masculine tiger does need these aids of course not. Via a specific organ, the Jacobson'sche organ, is the tiger able to determine precisely the status of a tigress. Through that withdraw the lips can reach this organ fragrance molecules that is localized by the palate. This course of events is also mentioned "flehmen".

The masculine tigers are normally all year union ready. One however, could find, that very young tigers can propagate herself if they had an experienced tigress at her "page". They should now still have questions on this subject or have another request, then do not hesitate you for me one enamel to write:
