Abstract:

Milk production, body condition, body weight and individual feed records for 196 2-yr-old heifers and their calves were used to evaluate sources of variation in weaning weight and its two major components, total energy consumption for the year and efficiency of energy use, defined as weaning weight divided by total energy for cow and calf. Four breed groups of cows including 29 Hereford, 73 Simmental × Hereford, 68 Angus × Hereford and 26 Tarentaise × Hereford were represented over the 6-yr period. Long-horn bulls sired the calves in all but the first 2 yr when Angus bulls were used. Sources of variation were evaluated by fixed model least squares and multiple regression analyses. The least squares analysis indicated the Hereford and Angus × Hereford differed only in level of condition both at calving and at weaning, with the Angus cross slightly fatter. The Simmental cross was highest in calving condition and equal to the Angus in weaning condition. The Simmental and Tarentaise crosses were similar and significantly different from the other breed groups in milk production and weaning weight of first calves. The Tarentaise cross was different from the other three groups in cow weight at weaning, cow efficiency and condition at weaning. The Tarentaise cross and Hereford group had lowest total cow and calf energy consumption, with Simmental cross highest and Angus cross intermediate. The Simmental cross achieved a high weaning weight through high energy consumption and slightly above average efficiency, while the Tarentaise group utilized high efficiency along with low energy consumption. The breed of dam by sex of calf interaction was significant for cow efficiency which has some implication for efficiency experiments that depend on group feeding. Standard partial regressions indicated that year followed by cow condition at weaning and milk production were leading sources of variation in weaning weight and efficiency. Year and cow weight at weaning were leading sources for total energy consumption. Cow weight at weaning was of least importance in determining weaning weight and efficiency. Key words: Weaning weight, cow efficiency, energy consumption, beef cattle

Abstract:

Forty-two multiparous dairy cows of three different breeds (Holstein, Montbéliarde and Tarentaise) were fed on the same type of forage (natural grassland) preserved in the form of either hay (H) or silage (GS), according to a changeover design (two 4 week periods). The proportion of concentrate in the diet and the energy and nitrogen contents were similar in both treatments. The milk produced by these cows was used for the manufacture of Saint-Nectaire type cheeses, under controlled and identical cheesemaking technological conditions. More cheese was produced with the H treatment milk. The cheeses made with the GS treatment milk were more yellow and tended to be more bitter. The other chemical and sensory characteristics did not differ much between the two treatments. Of the 51 volatile compounds identified, four were in significantly higher proportion in the GS than in the H cheeses. Cheeses produced from Tarentaise cows' milk were more yellow and their pH was higher than those made with the milk of Holstein or Montbéliarde cows. The cheeses from Montbéliarde and Tarentaise cows' milk were firmer, more melting and tastier than those made with the milk of Holstein cows. Although some trends were apparent, there were no significant differences in cheese volatile compounds for different breeds.

Abstract:

SummaryOne hundred and thirty-seven (Holstein (41), Montbéliarde (42) and Tarentaise (54)) dairy cows in first or second lactation received during winter one of two levels (high, H; low, L) of energy intake, and were later fed identically at pasture. Thrice in winter and twice at pasture, the chemical composition and coagulation properties of individual milks were measured. Milk from Holstein cows had lower casein and calcium contents, and poorer coagulation properties (curd firming time and curd firmness) than that from Montbéliardes and Tarentaises (P < 0·01). These differences practically disappeared when taking into account the distribution of the different κ-casein variants and milk casein content. κ-BB milks had coagulation properties 20–50% superior, according to characteristic, to those of AA milks. In the three breeds, animals from the H group had casein contents higher by 1·4 g/l than those of the L group, which induced a significant improvement in curd firming time, curd firmness and cheese yield. Turning out to pasture induced an increase of 0·02 in milk pH, and improved milk coagulation properties. These changes did not appear to result entirely from the parallel increase in milk casein content.

Abstract:

Abstract Ophiolites occur at several places in the Lower Penninic of the W and Central Alps. They are generally ascribed to oceanic crust of a so-called “Valais ocean” of Cretaceous age which plays a fundamental role in many models of Alpine paleogeography and geodynamics. The type locality and only observational base for the definition of a “Valais ocean” in the W Alps is the Versoyen ophiolitic complex, on the French-Italian boundary W of the Petit St-Bernard col. The idea of a “Valais ocean” is based on two propositions that are since 40 years the basis for most reconstructions of the Lower Penninic: (1) The Versoyen forms the (overturned) stratigraphic base of the Cretaceous-Tertiary Valais-Tarentaise series; and (2) it has a Cretaceous age. We present new field and isotopic data that severely challenge both propositions. (1) The base of the Versoyen ophiolite is a thrust. It overlies a wildflysch with blocks of Versoyen rocks, named the Méchandeur Formation. This “supra-Tarentaise” wildflysch has been confused with an (overturned) stratigraphic transition from the Versoyen to the Valais-Tarentaise series. Thus the contact Versoyen/Tarentaise is not stratigraphic but tectonic, and the Versoyen ophiolite has no link with the Valais basin. This thrust corresponds to an inverse metamorphic discontinuity and to an abrupt change in tectonic style. (2) The contact of the Versoyen complex with the overlying Triassic-Jurassic Petit St-Bernard (PSB) series is stratigraphic (and not tectonic as admitted by all authors since 50 years). Several types of sedimentary structures polarize it and show that the PSB series is younger than the Versoyen. Consequently the Versoyen ophiolitic complex is Paleozoic and forms the basement of the PSB Mesozoic sediments. They both belong to a single tectonic unit, named the Versoyen-Petit St-Bernard nappe. (3) Ion microprobe U-Pb isotopic data on zircons from the main gabbroic intrusion in the Versoyen complex give a crystallization age of 337.0 ± 4.1 Ma (Visean, Early Carboniferous). These zircons show typical oscillatory zoning and no overgrowth or corrosion, and are interpreted to date the Versoyen magmatism. These U-Pb data are in excellent agreement with our field observations and confirm the Paleozoic age of the Versoyen ophiolite. The existence of a “Valais ocean” of Cretaceous age in the W Alps becomes very improbable. The eclogite facies metamorphism of the Versoyen-Petit St-Bernard nappe results from an Alpine intra-continental subduction, guided by a Paleozoic oceanic suture. This is an example of the long term influence of inherited deep-seated structures on a much younger orogeny. This might well be a major cause of the inherent complexity of the Alps.

Abstract:

This study investigates genetic diversity and structure of native Egyptian cattle populations, called Baladi, as Saidi from Southern Egypt, Menufi from Mid-Delta and their F1 crosses with the French Tarentaise breed using DNA Microsatellite markers. A total of unrelated 97 individuals were genotyped utilizing eight SSR primers (ETH10, ETH225, BM1818, BM1824, BM2113, SPS115, TGLA53 and TGLA126). All utilized SSR were found to be polymorphic. The highest and lowest numbers of alleles detected were 16 and 6 at TGLA53 and SPS115 loci, respectively. Baladi-Tarentaise crosses (Bal-Tar) had the highest number of alleles over all. The PIC values of 7 loci were higher than 0.5, indicating high allelic variation of utilized markers. Estimated PIC values were up to 0.898, 0.866 and 0.873 for TGLA53 genotyped in Saidi, Menufi and Bal-Tar, respectively. Hobs values were lower than the expected ones in the native populations accompanied with positive values for Fis and significant deviation from HWE indicating inbreeding trend in native populations. Structure analysis indicated three ancestral genetic backgrounds. The native populations share two main backgrounds in almost equal percentages, while the Bal-Tar had the third one. The three populations showed low percentage of admixture. The studied Mediterranean cattle populations that belong to Egypt and France seem to have differentiated from each other with only little genetic exchange between the geographically isolated populations so local cattle is very similar.

Abstract:

SummaryTwo cases of livestock production involving French local breeds are analysed. The first shows how a high quality product under AOC (Protected Designation of Origin — PDO) has been defined for the Bresse chicken breed, formely kept by fancy breeders. The second shows the role of the local cattle breeds Abondance and Tarentaise in both the use of mountain areas and the development of PDO products. How to consider such values in a public policy dealing with farm animal genetic resources is discussed.

Abstract:

Cent trente sept vaches laitières de race Pie-Noir (41), Montbéliarde (42) ou Tarentaise (54), en première ou deuxième lactation, ont reçu au cours de l’hiver deux niveaux d’alimentation énergétique (haut : H et bas : B), et ont été ensuite alimentées de manière identique au pâturage. Des mesures individuelles de la composition chimique du lait et de son aptitude à la coagulation ont été réalisées 3 fois pendant l’hiver et 2 fois au pâturage. Chez les Pie-Noir, les taux de caséines et de calcium et l’aptitude à la coagulation (temps de raffermissement et fermeté du gel) ont été inférieurs (P<0,01) à ceux mesurés chez les vaches Montbéliardes et Tarentaises. Ces écarts disparaissent pratiquement lorsque l’on tient compte de la répartition des différents variants de la caséine kappa et de la teneur en caséines du lait. Les laits de type kappa BB ont présenté une aptitude à la coagulation supérieure de 20 à 50% selon les paramètres à ceux de type AA. Dans les 3 races, le lait des animaux du lot H ont présenté des taux de caséines supérieurs de 1,4 g/l à ceux des lots B, ce qui a entraîné une amélioration significative du temps de raffermissement, de la fermeté du gel et du rendement fromager. La mise à l’herbe s’est accompagnée d’une augmentation de 0,02 unité du pH du lait et d’une amélioration de son aptitude à la coagulation. Ces modifications ne semblent pas pouvoir être totalement expliquées par l’augmentation parallèle du taux de caséines du lait. L’aptitude du lait à la coagulation, mesurée chez les mêmes animaux au cours de leur 2 premières lactations, semble supérieure en deuxième lactation.

Abstract:

Le 3 juillet 1412 les représentants des communautés tarines de Landry et Peisey affirment devant les arbitres et médiateurs chargés de résoudre le conflit et ramener la paix, que la source première des tensions survenue entre les deux paroisses provient des limites jugées obscuri, obscures. La frontière et les éléments délimitant l’alpage de la Grassaz, commun entre les membres des communautés, nécessitent d’être retracées.Landry et Peisey sont confrontées, comme tant d’autres communautés médiévales et modernes, à la difficile et conflictuelle exploitation des ressources et des espaces communs qu’elles se partagent et particulièrement des alpages. Ces pâturages (pascua) de haute attitude, façonnés par l’Homme pour l’élevage du bétail depuis des millénaires, complètent la polyculture vivrière des paysans montagnards.Au travers de l’exemple de deux communautés rurales, cet article met en lumière les techniques de bornage, avec le traçage précis d’une frontière entre un espace commun, l’alpage de la Grassaz exploité conjointement par les communautés de Landry et Peisey, et le territoire propre aux habitants de Peisey.

Abstract:

Soixante dix-neuf vaches de race Tarentaise ont été utilisées au cours d’un essai de complémentation à l’alpage conduit 2 années consécutives. Au cours de la période estivale, tous les animaux pâturaient sur un alpage des Alpes du Nord, d’altitude comprise entre 1650 et 2200 m, conduit en pâturage rationné (renouvellement des parcs 2 fois par jour). Chaque année, au cours de l’ensemble de la période d’alpage, 2 lots ont été constitués : les vaches du lot Haut recevaient en moyenne 1,5 kg/j de concentré de plus que celles du lot Bas. L’effet du niveau des apports de concentré a été identique au cours des 2 étés : les vaches du lot Haut ont produit en moyenne 1,1 kg/j de lait de plus que celles du lot Bas (P<0,01), leur taux protéique a été légèrement plus élevé (+ 0,8 g/kg) et elles ont repris plus de poids vif (+ 6 kg) et d’état corporel (+ 0,4 point d’état) que celles du lot Bas. La reconstitution des réserves corporelles a été particulièrement faible chez les vaches du lot Bas en début de lactation à la montée à l’alpage. Ces résultats ont été comparés à ceux obtenus en zone de plaine, de demi-montagne ou sur d’autres alpages des Alpes du Nord.

Abstract:

Cet article présente un bilan de la variabilité génétique dans les huit principales races bovines laitières françaises établi à partir de l’information généalogique. La stratégie d’ouverture diffère entre populations, les races Normande et Tarentaise étant fermées, les races Prim’Holstein, Pie Rouge des Plaines, Brune et Simmental Française faisant largement appel à des gènes extérieurs, tandis que les races Montbéliarde et Abondance ont procédé à une légère infusion de gènes Holstein rouge. Lorsque la qualité des généalogies et la structure de la population permet de le calculer correctement, le niveau de consanguinité est faible mais il s’accroît assez rapidement, de l’ordre de 1 % par génération, ce qui correspond à un effectif génétique réalisé de quelques dizaines de reproducteurs. Le nombre d’ancêtres efficace, dérivé des probabilités d’origine de gènes, est compris entre 17 et 64 et n’est pas corrélé avec le nombre de femelles dans la population. Les races bovines laitières, du fait de l’efficacité de l’insémination artificielle, sont donc des populations extrêmement réduites en terme d’origines génétiques. Des études plus approfondies devront rapidement proposer des solutions visant à préserver la variabilité génétique, mais restant compatibles avec les programmes de sélection actuels. Sans préjuger des réponses à apporter, il semble cependant nécessaire, d’une part, de maintenir toutes les populations existantes et, d’autre part, d’augmenter le nombre de pères à taureaux.

Abstract:

SummaryImproved understanding of the adaptation of livestock breeds to their production environments is important for many decisions in the field of AnGR management, ranging from genetic improvement to conservation. However, adaptation is complex and difficult to measure. One approach to this problem is to characterize adaptation indirectly by describing the production environments in which a breed has been kept over time, and to which it has probably become adapted. Comprehensive and comparable descriptions of the production environments in which animals are kept are also needed to make meaningful evaluations of performance data and to enable comparative analysis of the performance of different breeds. To address these requirements and in accordance with the Global Plan of Action for Animal Genetic Resources, it has been proposed that a recognized set of “production environment descriptors“ should be established and used throughout the world as a common framework for describing breeds' production environments. An important aspect of the process will be the georeferencing of breed distributions, which will allow them to be linked to a range of existing georeferenced data sets (e.g. climatic data). The link between a breed and a specific production environment may offer a basis for the development of a niche market; examples in include the Bresse chicken of France and the Abondance and Tarentaise cattle breeds of the northern Alps. Such niche markets represent important opportunities for keeping traditional breeds in use.

Abstract:

A comparative dendroecological study was carried out in an alpine valley of France (Haute-Tarentaise, Savoie) to analyze the climatic influence on the radial growth of the silver fir (Abies alba Mill.) and the Norway spruce (Picea abies Karst.). Ten populations were sampled at three altitudes on two exposures (North and South). For each population, a chronology of ring-width indices was standardized with a 7-year weighted moving average and with a residue chronology by autoregressive modelling. Then, correlation functions were calculated between growth indices standardized with both methods and climate with an iterative process (bootstrap). The climatic window used here covers 3 years, with mean monthly data of precipitation and temperature. The summer is the most important period for the spruce, which shows a transition along the altitude. This species is successively sensitive to drought at the lower level (year n of ring formation), sensitive to the previous hot summer (n - 1) at the intermediate level, and sensitive to the cold the same year (n) at the upper level. Fir growth is favoured by a rainy previous summer (n - 1) and a hot summer n at the highest altitude on northern slopes, with a difference between northern and southern slopes stronger than for spruce. The interspecific comparison reveals that the fir uses soil water more efficiently and is thermophile, whereas the spruce is more sensible to summer drought. The influence of the year preceding ring formation appears with both methods of standardization and seems to show a real physiological effect.

Abstract:

Abstract. Glacier mass balance (MB) data are crucial to understanding and quantifying the regional effects of climate on glaciers and the high-mountain water cycle, yet observations cover only a small fraction of glaciers in the world. We present a dataset of annual glacier-wide mass balance of all the glaciers in the French Alps for the 1967–2015 period. This dataset has been reconstructed using deep learning (i.e. a deep artificial neural network) based on direct MB observations and remote-sensing annual estimates, meteorological reanalyses and topographical data from glacier inventories. The method's validity was assessed previously through an extensive cross-validation against a dataset of 32 glaciers, with an estimated average error (RMSE) of 0.55 mw.e.a-1, an explained variance (r2) of 75 % and an average bias of −0.021 mw.e.a-1. We estimate an average regional area-weighted glacier-wide MB of −0.69±0.21 (1σ) mw.e.a-1 for the 1967–2015 period with negative mass balances in the 1970s (−0.44 mw.e.a-1), moderately negative in the 1980s (−0.16 mw.e.a-1) and an increasing negative trend from the 1990s onwards, up to −1.26 mw.e.a-1 in the 2010s. Following a topographical and regional analysis, we estimate that the massifs with the highest mass losses for the 1967–2015 period are the Chablais (−0.93 mw.e.a-1), Champsaur (−0.86 mw.e.a-1), and Haute-Maurienne and Ubaye ranges (−0.84 mw.e.a-1 each), and the ones presenting the lowest mass losses are the Mont-Blanc (−0.68 mw.e.a-1), Oisans and Haute-Tarentaise ranges (−0.75 mw.e.a-1 each). This dataset – available at https://doi.org/10.5281/zenodo.3925378 (Bolibar et al., 2020a) – provides relevant and timely data for studies in the fields of glaciology, hydrology and ecology in the French Alps in need of regional or glacier-specific annual net glacier mass changes in glacierized catchments.

Abstract:

The casein micelles of bovine milk are large aggregates of roughly spherical shape consisting of the four phosphoproteins αs1-, αs2-, β- and κ-casein (CN). They are polydisperse colloidal particles with weight-average diameters between about 50 and 500 nm (Horne, 1984). Since αs1-, αs2- and β-CN are sensitive to calcium it is assumed that they are located predominantly within the micelle, whereas κ-CN is mainly on the surface of the micelles and serves as a stabilizer for the aggregates owing to its hydrophilic C-terminus. Inorganic calcium phosphate interacts with the phosphate groups of the caseins. This conformation of caseins, calcium and phosphate also contains small amounts of magnesium and citrate. Of the dry matter of the micelle, ∼93% is casein and ∼7% inorganic components, mainly calcium and phosphate (McMahon & Brown, 1984; Holt & Horne, 1996).In several studies it has been demonstrated that milk with the κ-CN B variant has on average smaller micelles than κ-CN A milk (Morini et al. 1975; Nuyts Petit et al. 1997). Compared with κ-CN variants, there are only a few studies on the association of αs1-, αs2- and β-CN variants with casein content and micelle size. In the milk of β-casein-deficient mice, casein micelles were smaller than in normal mouse milk but still present. The lack of β-CN was partly compensated by an increased whey protein content (Kumar et al. 1994). A comparison of the cheesemaking properties of Tarentaise milks containing the A (A1 or A2, without distinguishing between these variants) and C variants of β-CN revealed that the most significant characteristic for discriminating the two types of milk is the average diameter of the casein micelles: 293 nm in β-CN C type milk, 187 nm in the A type (Delacroix-Buchet & Marie, 1994).The objective of the present study was to investigate the micelle size and the casein composition of milk from half sibs within Simmentals cross bred with Red Holsteins (Simmentaler Fleckvieh, SI×RH) sires heterozygous for A1A2 of β-CN.

Abstract:

En 1985, un programme de Recherche-Développement a été mis en place dans les Alpes du Nord pour répondre aux questions spécifiques posées par la filière laitière de cette région. Une partie des travaux de ce programme a concerné la caractérisation des animaux et des aliments. Ils ont montré que les vaches de races locales (Tarentaises en particulier) présentaient des aptitudes particulières (meilleures performances de reproduction, moindre précocité sexuelle, traite plus difficile, meilleure aptitude à la marche) comparativement à des vaches Holstein conduites dans les mêmes conditions, mais que leur rationnement pouvait être réalisé selon les recommandations mises au point avec ces animaux. L’étude des relations entre les facteurs de production du lait et les caractéristiques physico-chimiques et sensorielles des fromages a mis en évidence un effet des caractéristiques génétiques des animaux (variant C de la caséine bêta), du stade de lactation et de la nature de l’alimentation (en particulier la nature des pelouses d’alpage) sur la qualité des fromages. Ces résultats donnent des indications précieuses aux différents agents de la filière pour raisonner la conduite des animaux dans un objectif de production de fromages présentant une forte typicité.

Abstract:

Les variations de la numération cellulaire du lait ont été analysées sur 404 lactations de 208 vaches laitières conduites sur un domaine expérimental de l’INRA et indemnes de mammites cliniques au cours des lactations considérées. En moyenne, la numération cellulaire a été minimale en 2ème mois de lactation (50 000 cellules/ml) et maximale en fin de lactation (200 000 cellules/ml). Les vaches primipares ont présenté des numérations plus élevées que les multipares en début de lactation et plus faibles en fin de lactation. Les vaches Holstein ont présenté des numérations cellulaires constamment supérieures à celles des vaches Montbéliardes et Tarentaises. En fin de lactation, l’écart entre ces 2 groupes d’animaux atteint environ 120 000 cellules/ml. Cet effet de la race n’est pas dû à un effet du niveau de production. Chez les vaches multipares, la présence de plus d’une mammite au cours des lactations précédentes a conduit à des numérations cellulaires significativement plus élevées (d’environ 40 000 cellules/ml à l’échelle de la lactation) que chez les vaches ayant présenté une mammite ou pas du tout au cours des lactations précédentes. La numération cellulaire augmente légèrement, indépendamment de l’effet du stade de lactation, au cours des mois d’août et septembre. L’ensemble de ces facteurs de variations ne permettent cependant pas d’expliquer des numérations cellulaires supérieures à 300 000 cellules/ml dans un lait de mélange.
