French milk recording results – Sheep – Year 2013 – p. 1

Introduction
The research and development process in genetic improvement of dairy sheep successively dealt with productivity of ewes
and herds (during the 70s and 80s), chemical milk composition and its suitability for cheese production (during the 80s and
90s), finally functional abilities such as resistance to subclinical mastitis and udder morphology (2000 decade). These
functional characteristics enable the animals’ functional longevity to be improved. This improvement matches with their
ability to postpone their culling for other reasons than those linked with their milk yield level. In other words, functional
longevity contributes to have flocks with a better cost-effectiveness, not by increasing takings, but by decreasing production
costs through reduced early culling. Genomics has been fully involved during these last years in dairy sheep breeding
schemes with, on one hand, the selection for resistance to scrapie thanks to the genetic typing of the PrP gene widely
implemented right at the beginning of the 2000s, on the other hand genomic breeding prospects which are subject to
Roquefort’in (Lacaune breed) and Genomia (Pyrenean dairy sheep breeds – Manech and Basco-Béarnaise) programmes.
From year 2015 onwards (choice of young rams at the end of 2014), Lacaune breed will shift towards a genomic selection
with a new scheme design.
The genetic improvement of dairy sheep within the three French traditional breeding areas (“Rayon”de Roquefort, PyrénéesAtlantiques, Corse) is based on the breeding of local breeds within their own production area and systems. This principle is
strengthened by the French AOC label (which guarantees the origin of a product) of each area. This label requires the local
breed as the genetic material to be used for the cheese production of Roquefort (Lacaune breed), of Issau-Iraty (BascoBéarnaise and Manech breeds) and Brucciu (Corse breed). The implementation of dairy sheep breeding programmes is based
on milk recording and progeny testing of animal insemination rams. It has systematically been well-reasoned in order to
increase its efficiency-cost ratio.
Pyramidal structure of the population
Breeds’ population is organized on the basis of a pyramidal structure made up of breeders, creators of the genetic gain and
farmers using genetic gain, in order to select the local breeds in population-wide terms. Selection tools are gathered in flocks
of breeders who are registered at the official milk recording organizations. These tools include qualitative recording and
breeding animals’ qualification with possibly udder scoring. Breeding flocks serve as a testing medium and provide the
breeding centers with young rams. Testing has been developed in order to maximize breeding schemes. The effort required
for its implementation is considerable as (depending on the breeds) 50 to 60 % of the inseminated ewes within a flock under
breeding are inseminated with tested rams. Breeders receive as compensation inseminations with the elite rams, i.e. the sires
of the breed’s rams. If they wish it, the breeders who use the genetic gain may receive a simplified milk recording. Its
objective is firstly to get a within-flock ranking of the ewes, but also the technical monitoring of the dairy flock.
Rationalization and optimization over the time
Breeding objectives have been planned gradually. Official milk recording implemented in the 60s was at the beginning only a
quantitative control (milk yield) due to the industry needs of milk on one hand, and because of the low initial productivity of
the French local breeds on the other hand. The first objective was clearly to increase ewes’ productivity. The breeding criteria
taken in consideration was the milk yield during the milking period which steps up fat and protein contents quantities, and
thereby cheese quantities.
Such an objective may be accepted during the start-up period of the breeding scheme. However, when this objective is fully
operational and becomes completely effective (in the 80s for the Lacaune breed, in the 90s – 2000s for the Pyrenean breeds),
the milk quality (fat and protein contents) deteriorates on a genetic level speaking. Thus, it is becoming essential to be
interested in the chemical quality of the milk also in order to know about cheese yield and the fat/dry ratio of cheese in the
framework of AOC cheese produced with raw milk and whole milk. That’s why a qualitative recording was to be performed,
although it is difficult and expensive to implement in dairy sheep because of the flocks’ size and the rapid mechanical
milking routines.
Finally, when the context of the industry was such as productivity was no longer directly looked for, breeders became then
interested in functional characteristics which are going to enable to decrease production costs and to improve work
conditions, especially milking conditions which represent the first work station of dairy ewes’ breeding.
Today, farmers and stakeholders of selection schemes raise the question of hardiness and plasticity and evoke the wish to
work on resistance to gastro intestinal parasitism, dairy persistency, ability to one-milking per day, feed efficiency, but also
the ability to transhumance and at the valorization of rangelands.
Milk recording simplification
The official AC design (monthly recording of one of the two daily milkings, whatever the milking) has been widespread. The
qualitative recording has been even more simplified. Only a part of the ewes is recorded: the primiparous (Pyrenean breeds)
or the first two lactations (Lacaune breed). Only the middle of the lactation is controlled, because it is the most representative
period from a genetic point of view. Thus, the objective is to carry out three samples at the first four test-days of the ewe
during the morning milking. The morning milking enables a better milk sampling, especially of the fat content and somatic
cells. The partial recording as described here above enables to save about 85% of the samplings and analyses in order to get
an efficiency a bet lower (the loss of precision may easily be compensated for rams by increasing the testing daughters’
number by about 10%), compared to the exhaustive A4 recording method (on a monthly rhythm for the two daily milkings
and for all the ewes on milking). This process is also systematically used for functional characteristics.

Data processing
Annual results of the sheep official milk recording are calculated from an extract of the French national dairy sheep database
used for indexing and research, which is part of the SIEOL Information System. This extract was performed at the end of the
dairy sheep year in December 2013. Thus, these results concern the year 2013. Regarding the seasonality of the dairy sheep
production in France, all lactations are considered as finished and qualified if they are calculated.
The results are presented by breeding area, French local administrative area (=French “département”), Milk Recording
Organization (MRO), Performance Testing organization and by breed.
Here are the definitions of these terms:
Breeding areas: 1 = ‘Rayon de Roquefort’ ; 2 = ‘Corse’ ; 3 = ‘Pyrénées-Atlantiques’
French local administrative areas (= French “départements”): Aude, Aveyron, Corse du Sud, Haute Corse, Gard, Hérault,
Lozère, Pyrénées Atlantiques, Hautes Pyrénées, Tarn, Tarn et Garonne.
Milk Recording Organizations (= MRO): ‘CDEO’, ‘Confédération Générale de Roquefort’ , ‘EDE 48’ , ‘EDE 81’ , ‘EDE
82’ , ‘SCP 30-34’ , ‘SUAE Corse du Sud’ , ‘SUAE Haute-Corse’ , ‘UNOTEC 12’
Recognized Performance RecordingOrganizations (= RPRO): ‘CDEO’, ‘OS Lacaune’ , ‘EDE 82’, ‘SUAE Corse du
Sud’ , ‘SUAE Haute-Corse’
Breeds: ‘Lacaune’, ‘Manech Tête Rousse’ , ‘Manech Tête Noire’ , ‘Basco-Béarnaise’ , ‘Corse’. Other breeds representing
less than 50 ewes nationwide are not taken into account in these results.
NB: In paragraphs 2.2 to 2.6, maps only show French local administrative areas (=French “départements”) where at least 10
lactations haven been calculated for the corresponding breed.
Warning:
Results between breeds or populations (Basco-Béarnaise, Corse, Lacaune, Manech Tête Rousse, Manech Tête Noire) should
not be compared, mainly for two reasons:
 each breed is represented only in one breeding area. Therefore, genetic type and dominant farming system(s) of each
French administrative region are closely linked.
 the calculation of milk yield at milking period varies from one region to another (and for breeds accordingly), in
relation with the average suckling length, depending on the farming system:
- 25 days in the area of Roquefort,
- 35 days in the Pyreneans and in Corse.
Some definitions:
Total number of ewes: ewes present in the flock at the beginning of the lambing period.
Number of ewes in lactation: ewes for which calculating a lactation has been possible (so this total takes into account
ewes that had at least one test-date with non-null milk production record).
Number of ewes that lambed: ewes with a date of lambing, non-pregnant ewes, aborted ewes without milk and not
mated ewe in 1st lactation are therefore excluded from this total.
Lambing rate: number of ewes which lambed divided by the total number of ewes (expressed in %).
Lactation rate: number of ewes with calculation of lactation divided by the number of ewes which lambed (expressed
in %).
Milk yield: it represents the milk yield at the milking-only period. This milk yield is calculated only on the period
of exclusive milking of the animal after the weaning of the lamb(s), and doesn’t take into account the milk yield
during the initial period of suckling or suckling x milking. So the milking length matches only to this milking-only
period. The milk yield is expressed in liters and the length in days.
The official milk recording is an AC milk recording protocol, i.e. a monthly control of one of the two daily milkings,
without any obligation of rotation. However, the recording occurs mainly in the morning because the sampling for the
qualitative control is more precise during the morning milking (more milk in the morning).
Results for fat and protein contents are not provided. The sheep qualitative control is indeed a very simplified control
(partial qualitative recording). It is based on a sampling performed only at the milking of the morning, on 3 recordings
during the middle of the lactation and it concerns only a part of the flock (the primiparous or the first 2 lactations,
depending on the breed). The way of recording and calculating the fat and protein contents are relevant for genetics,
but are not representative of current economic reality.
CNBL
Trends for 2013
The total number of ewes present in the flock at the lambing period reached 304,925 in 2013, i.e. an increase of 0.9%
compared to the previous year. The total of ewes in official milk recording had remained fairly stable (about 300,000 ewes)
over the last ten years. The total of ewes with lactation calculation reached 259,666 in 2013 and remained stable too.
The number of flocks which provided lactations results decreased by 0,5%. Except the year 2012 where the number of flocks
has stabilized, the decrease is constant since 2004 : there were 835 flocks in official milk recording in 2004, there are 759
today. Only the increasing size of the flocks allows maintaining the number of ewes in milk recording.
The average milk yield, which was over 250 liters in 2012, decreased in 2013 to reach 247.5 liters in 164 milking days.
A simplified milk recording not identified and presented here exists in addition to the official milk recording design. It
concerns all farmers (while the official milk recording is reserved only to breeders). 1,342 flocks and 536,460 ewes present at
the lambing period were registered in 2013 (last complete figures).
