NUCLEUS has developed with IFIP and INRA a genomic program in Landrace. The main is to get a faster genetic progress already carried out (see new from 29/08/16) in Maternal Qualities and in particular in Number of Piglets Born Alive. Precision of breeding values will also increase thanks to this genomic program.
The first genotyped boars have entered in AIC during the 2nd semester of 2016. Gilts for auto-renewing of selection farms are now also genotyped.
In February 2016, NUCLEUS has exported to Benin Large-White animals. The aim of this importation is multiplication and sales to production farms.
Benin has been really affected by African Swine Fever and has to renew its park of breeding animals.
This exportation was a successfull and after to pass a conformity control, animals are very well adapted in their new farm.

Once again the work done by NUCLEUS has been recognized by the International Press.
NUCLEUS is working at different and numerous levels to provide solution for tomorrow as it's mentionned on the following article of the last International Pig Topics.
You will find below the link to this article.
Come to see us at EUROTIER from 15th to 18th of November in Hannover, Germany
We will be very pleased to meet you on our booth :
NUCLEUS will present its last innovations and genetic progress done on its different purebreed lines
Since the new breeding goal has been launched in 2014 in female lines Large White and Landrace, the average weight of piglets at birth and the homogeneity of weight of piglets at birth are included in the breeding goal. These two criteria are taken into account in order to select gilts and boars, which in parallel to the increase of prolificacy, maintain or improve the average birth weight o piglets and the homogeneity of weight of piglets. In no case the increase of prolificacy shall induce a decrease in average birth weight or an increase of the heterogeneity of weight of piglets.
The table below shows the evolution, in Large White breed, of
- the average birth weight of piglets
- the homogeneity of birth weight of piglets within a litter.
|
Number of weighted piglets |
Average individual birth weight |
Standard deviation of individual birth weight |
2015 |
50 487 |
1.379 kg |
0.287 kg |
2014 |
51 671 |
1.372 kg |
0.286 kg |
2013 |
47 467 |
1.379 kg |
0.287 kg |
These data confirm the full efficiency of the breeding goal. The increase of prolificacy did not get negative impact neither on the average birth weight nor in the homogeneity of birth weight.
As usual, NUCLEUS will be present to SPACE 2016 from September 13 to 16 in Rennes (France), Hall 8, booth A24. We invite you to meet us during this fair.
The first aim of a breeding scheme is to define the criteria to improve and then to identify and to select within its purebred population the animals improving these criteria. The identification of these improver animals enable to carry out genetic progress. The best boars selected and placed in artificial insemination center enable the diffusion of the genetic progress.
In female lines, the improvement of Maternal Qualities has been defined has priority and in particular the increase of prolificacy.
The tables below show the genetic progress done in the selection farms Large White and Landrace from 2012 to 2015.

The evolution of prolificacy in Large White and Landrace shows the efficiency of the new breeding goal and of the breeding methods applied daily.
70 boars NUCLEUS Landrace boars are present in artificial insemination centre in France. These boars are used for the renewing of pure breed GGP Landrace sows of selection farms but also and mainly for the production of F1 sows by insemination of Large White GP sows on multiplication farms.
The table below details the average performances of the mothers of these 70 boars present in French AIC on the 1st of January 2016.

Performances of the mothers of these 70 boars are simply remarkable!
The quality of NUCLEUS breeding evaluation has been recognized by international Pig Topics.
One detailed and well illustrated article has been published on the famous pig review.
