Sánchez-Osorio stocks which sides of control are very important for maximizing the TN70’s possible.
At the start, he tells us that aside from the intensive control and vitamin manuals, there may be a smaller model within the type of recommendation and sensible knowledge (guidelines). Extra not too long ago, there may be an app to be had for any mobile phone, with elementary control and feeding suggestions for the TN70.
Sánchez-Osorio emphasizes that the number of long run breeding sows starts even earlier than they’re born. It is necessary that the dam’s frame situation at weaning is excellent as a result of this may occasionally affect estrus within the following cycle and the standard of the oocytes and embryos, with the ensuing affect at the high quality of the piglet born.
Gilt building
He additionally stresses the significance of the longer term breeding sow’s enlargement section. Even supposing this section is dependent an increasing number of much less at the genetics provider, as many purchasers produce their very own alternative gilts, it is vital that they practice Topigs Norsvin’s suggestions for feeding long run breeding sows.
Excellent number of piglets from start is very important. Handiest essential piglets with excellent start weights and no less than 14 teats (for TN70s this goal will also be 16) must be known as possible long run breeding gilts.
TN70 alternative gilts expand and develop speedy, are lean, and feature a excellent urge for food. Really helpful weight curves and feeding methods take this into consideration and save you too fast enlargement within the juvenile section (25 to 55 kg). We suggest that gilts all through their building should be fed advert libitum, however in a managed approach, by way of decreasing nutritional power and feeding in 3 stages. The primary two stages (25-55 kg and 55-100 kg) purpose to make sure ok frame and skeletal building. Within the 3rd section, we purpose to organize the sow for her first gestation. If offering 3 stages isn’t an choice, our nutritionists can counsel intermediate answers tailored to the prerequisites of each and every farm.
Weight in the beginning provider
The objective weight at mating is 150-160 kg, at round 240 days of age (220-240). The significance of the age/weight courting is emphasised, which is probably not the similar in all prerequisites. The objective must be to reach a enlargement of 650g/day from start to mating. The age in the beginning provider must be contingent on achieving the minimal weight discussed and making sure that it’s no less than the second one or 3rd warmth.
Sánchez-Osorio provides that it would not be sufficient to understand the load in the beginning provider, however preferably, the load in the beginning farrowing and primary weaning must be monitored, because the sow’s building all through this primary parity has an instantaneous affect at the sow’s longevity.
Control in the beginning provider
It’s endorsed that boar publicity start at 5-6 months. It’s been noticed that this early publicity favors better uterine building and higher efficiency during her reproductive lifestyles.
Relating to mating, there aren’t any important variations with appreciate to different hybrids: Mating at the second one or 3rd estrus, the TN70 sow sticks out for appearing transparent indicators of ouestrus.
Crate acclimation must be accomplished for at least 15 days, and it’s also really useful to do a particular flushing all through the former 15 days. If it’s not conceivable to have a particular vitamin, no less than give an additional provide of dextrose and make sure a prime feed consumption all through this section.
Feeding curve
In gestation, it is very important to make certain that the sow continues her herbal frame building along with supporting the advance of gestation. Sánchez-Osorio tells us that if conceivable, two other feeds must be utilized in gestation, one for early and mid-gestation and any other for overdue gestation. The aim of the feed for the primary section of gestation is to get well frame situation. The feed for the second one section is to want fetal building in an effort to enhance start weight. If enforcing the 2 diets is difficult, only one gestation vitamin can be utilized however it must be balanced to stimulate weight achieve by way of gestation within the youngest women folk and, on the identical time, to keep watch over the frame weight of upper parity sows.
In weaned sows, dietary wishes are upper initially of gestation and once more on the finish of gestation, when fetal enlargement and mammary building are at their top. In gilts, necessities practice an upward curve during gestation to toughen the sow’s frame building (Desk 1).

As soon as within the farrowing room, it might be perfect to present a peripartum feed from the access into the room till the second one or 3rd day after farrowing. The benefit of a transition vitamin is that the volume of feed will also be higher earlier than farrowing with no need any unfavorable impact on udder building and the onset of milk manufacturing, combating constipation and conserving them calm. Some other side to be careful for is that there’s continuity within the composition of the gestation and lactation diets.
In lactation, frame situation losses must be lower than 10% of frame weight. After farrowing, a steady, sluggish building up is selected. The purpose is to keep away from overfeeding the sow by way of looking to building up too speedy, which might have the other impact. The concern is that beginning the Eighth-Ninth day, the feed consumption must be the utmost asked by way of the sow.

Farrowing control
Sánchez-Osorio refers us to the former article at the TN70 variety standards. As he defined there, Topigs Norsvin has sought to make certain that any building up in overall born is accompanied by way of an building up in born alive and an building up within the selection of teats. Consistent with him, this explains why the TN70 does now not require very explicit control referring to farrowing help or cross-fostering as this can be a sow with excellent control and prime milk capability.
In farms with excellent prerequisites, the manufacturing function must be between 15-16 born alive and 13-14 piglets weaned in line with sow.
This sow can paintings with lactations between 21 and 28 days and will download weaning weights just about or above 7 kg at 28 days.
