Consulter le resumé

Les Cahiers de l'IFIP, 5(2), 1-7 - La revue R&D de la filière porcine française

Après avoir capitalisé des données antérieures, les partenaires du projet Valormap ont procédé à une étude de gisement des co-produits potentiellement intéressants pour la méthanisation au sein de leurs filières respectives. Cette enquête a permis en outre d’établir ou de réactualiser des ratios de production et d’échantillonner ces co-produits à des fins d’analyse. Le potentiel méthanogène et les concentrations en matières sèches et organiques, azotes ammoniacal et total, phosphore et potassium ont ainsi été déterminés sur plus de 90 déchets des industries agro-alimentaires. Les auteurs du projet ont réalisé plus d’une vingtaine de fiches « co-produits » où figurent les informations essentielles les concernant. Pour les grandes catégories de déchets organiques identifiés dans ce projet, un outil web public donne accès aux masses correspondantes à l’échelle départementale et aux quantités d’énergie correspondantes, sous forme de KWh et de Nm³ CH₄, à l’échelle cantonale. L’ensemble des résultats sont disponibles sur le site du projet (https://www.valormap.fr/).

Feed eco-design: how to make a good decision? Part 2- rebound effects of eco-feed production

Consulter le resumé

Sandrine Espagnol et al., 11th International conference on life assessment of food 2018 (LCA Food), 17-19 octobre 2018, Bangkok, Thaïlande

This study takes place in a context where the feed manufacturers have access to eco-labeling databases which allow them to do eco-design and produce feeds with less environmental impacts. First results of eco-feed show substitutions between feedstuffs compared to standard feed. Therefore, the objective of this study is to identify the rebound effects of the production of eco-feed for pigs if the practice becomes widespread in France. A mind map was built with 5 experts to identify in a qualitative way the panel of different consequences. We then focused on the one concerning the change of crop rotations to produce eco-feed. We chose a virtual territory dedicated to produce the feedstuffs for a pig farm and assessed the environmental impacts by LCA using different functional units and perimeters. The situation with the production of eco-feeds can appeared better or worse compared to the production of standard feeds. This work underlines the complexity of eco-design and the limit to do it with data from attributional LCA. It is necessary to complete the databases by information to make the users aware of the rebounds effects invisible during the eco-design process.

Diversité des productions porcines en France

Consulter le resumé

Jean-Yves Dourmad et al., Innovations agronomiques (FRA), 2018, volume 68, octobre, p. 151-170

Alors que la production porcine française est souvent perçue comme uniforme, il existe une assez grande diversité en termes d'organisation et taille des élevages et d'insertion dans l'exploitation agricole. Les élevages spécialisés représentent 39% des exploitations et 61% du cheptel alors que pour 38% des exploitations l'élevage porcin est associé à la présence de bovins. Au niveau des produits la diversification est surtout assurée en aval par le tri des carcasses et des pièces de découpe, et la transformation. Le porc est en effet valorisé à 75% sous la forme d'une grande diversité de produits transformés qui contraste avec la faible diversité de l'offre en viande fraiche. Depuis quelques années on assiste au développement de différentes démarches valorisant l'origine ou le mode d'élevage. Les leviers de différenciation concernent souvent plusieurs dimensions comme la race des animaux, l'origine géographique des produits, leurs qualités organoleptique ou diététique, l'absence ou la présence de certains composés dans l'alimentation des animaux, le bien-être animal et la production biologique. Cette évolution est favorisée par le renforcement des liens entre les groupements de producteurs et l'aval, y compris jusqu’à la transformation et la distribution.

Diversity of pig production in France

Although French pig production is generally perceived as uniform, a rather large diversity still exists in terms of organization and size of pig units and their integration with the rest of the farm. Specialized pig farms represent 39% of all pig farms and they raise about 61% of all pigs, whereas in 38% of farms the raising of pigs is associated with ruminants. Diversity of pork products is mainly obtained by the sorting of carcasses and cuts, and their processing. Indeed, in France, about 75% of pork is consumed after processing, with a very large diversity of products. This contrasts with the rather low diversity of pork fresh meat. Nevertheless, in the recent years, we may observe the development of strategies of diversification based on the origin or the way of production. The differentiation levers may combine different dimensions among: animal breed, geographic origin, organoleptic and dietetic quality, the absence or the presence of specific compounds in animal feed, animal welfare, and organic production.
This evolution towards increased diversity is promoted by the consolidation of the links between pig producer cooperatives and the downstream of the pork production chain, including processing and distribution sectors.

Relationship between age and body weight at farrowing over 6 parities in Large White × Landrace sow

Consulter le resumé

Nathalie Quiniou, 69th Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018 

At the beginning of the gestation, parity and back fat (BT) thickness are frequently used by farmers to choose among different feeding plans the most adapted one to feed each sow if individual feeding is possible. Otherwise, BT is used to allocate the sows to one of the available pens and to adapt the feed allowance at the group level. Usually a single target of BT at farrowing is retained at the herd scale, and each sow is expected to make up its BT for the difference between the target and its own initial BT. According to the factorial approach used to assess nutrient requirements, achieving an expected BT gain implies that enough energy is supplied above maintenance. Based on equation published by Dourmad et al., expected energy retention is obtained by the difference between the initial (calculated from measured BT and BW) and the final amount of energy (calculated from expected BT and BW).
When no information is collected on BW during the gestation, the expected final BW is also used to assess daily BW and corresponding maintenance requirement and to take into account impacts of housing conditions (temperature, activity level). Then, adequacy of the energy supply depends not only on initial and final BT, but also on initial BW and final BW. Individual BW have been collected over successive parities in the IFIP facilities (n=6,288 from Large White × Landrace sows born since 2000). Data of 90 sows born between 2012 and 2015, studied over at least 6 parities and group-housed from the 28th to the 108th day of gestation, were used to characterize the relationship between age and BW after farrowing based on BW at the first farrowing (BW_P1) and BW gain afterwards, with BW at the 6th parity considered as the mature BW: BWi(Age), kg = 145.6 + 0.171 × Age_P1i+ 111.4 × (1 – exp(- 1.453/1000 × (Age-Age_P1i)1.084)), RMSEP=16 kg; with Age_P1i: the individual age at the first farrowing used to adjust the mean BW_P1. Based on this equation, the individual expected BW gain (both growth and recovering parts) can be calculated and, combined with BT gain, used to assess the corresponding energy requirement for precision feeding during gestation. Its calibration for other lines or farms will require specific measurements due to interactions with management.

Precision feeding with a decision support tool dealing with daily and individual pigs’ body weight

Consulter le resumé

Nathalie Quiniou (IFIP) Michel Marcon (IFIP) et Ludovic Brossard (INRA), 69h Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018 

Nutritionists, feed companies and equipment manufacturers look for solutions that help farmers to improve sustainability of pig production. Based on experimental results obtained in silico or in vivo, a better adequacy between amino acid supplies and requirements increases feed efficiency and farmer’s income and reduces the environmental impact of growing pigs, highlighting the interest for precision feeding. Data are collected to characterize daily animal traits (e.g. body weight, BW) and their variation from one day to another (e.g. growth rate, &‘6;BW). They are used to determine the requirement for maintenance and growth on the next day, respectively. Therefore, adequacy between requirements and supplies depends on these predicted BW and &‘6;BW. The double exponential smoothing (Holt-Winters) method with a smoothing parameter &”5;=0.6 (HW0.6), presents a low sensitivity to the number of latest values used to forecast BW. It seems to allow for a secured prediction of BW soon after the beginning of the growing phase (at least after 4 days). A group of pigs was used in restricted feeding conditions to compare results obtained either with a 2-phase feeding strategy, considered as the control treatment, or a precision feeding strategy based on BW forecasting with the HW0.6 method. Pigs allocated to both treatments were group-housed in the same pen, equipped with the decision support system built in the Feed-a-Gene project to manage the data, to determine in real-time the corresponding nutritional requirements, and to adapt the feed characteristics provided to each pig through the blend of two diets (9.75 MJ net energy/kg, 0.5 or 1.0 g of digestible lysine per MJ). Available results from 24 pigs per treatment indicate that overall average growth performance were not influenced by the feeding strategy (P>0.58 for both average daily gain and feed conversion ratio) but digestible lysine intake was reduced by 6% (1,774 vs 1,879 g, P<0.01) and N output by 7% (P<0.01) with precision feeding. Results will be completed by a second group using the same treatments. This study is part of the Feed-a-Gene project and received funding from the European Union’s H2020 program under grant agreement no. 633531.

Evaluation of micropollutants and chemical residues in organic and conventional pig meat

G Dervilly-Pinel (ONIRIS) et al., 69h Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018

Even if there is no clear evidence that organic food products are healthier than conventional ones, the presumed absence of chemical contaminants is reported as main driver for organic consumers.. To provide occurrence data in a context of chronic exposure, samples of liver and meat (psoas major muscle) were collected in 2014 in six French slaughterhouses representing 70 pig farms, including 30 organic, 12 Label Rouge and 28 conventional. Each sample corresponded to a pool of tissues of three carcasses. Environmental contaminants (17 polychlorinated dibenzodioxins/ dibenzofurans (Dioxins), 18 polychlorinated biphenyls (PCBs), 3 hexabromocyclododecane (HBCD) isomers, 6 mycotoxins, 6 trace metal elements) and residues from production inputs (75 antimicrobials and 121 pesticides) were investigated using the most sensitive methods. Contamination levels were measured below regulatory limits in all the samples. However, some differences were observed between types of farming. Dioxins, PCBs and HBCD concentrations were thus observed as significantly higher in organic meat samples. Cu, Zn and As were measured at slightly higher levels in organic meat without differences between organic and Label Rouge. Liver samples from conventional and Label Rouge farms exhibited higher contents in Zn and Cd than the organic ones. Ochratoxin A was the only mycotoxin quantified in 25 samples (36%) and detected in another 22 samples (31%) of the livers analysed, without significant differences between farming systems. A correlation could be observed between mycotoxins concentrations in meat and liver. All meat samples exhibited pesticides levels below the detection limits, whereas only 3 conventional or organic samples (overall: 3.5%) displayed residual concentrations of authorized veterinary antimicrobials, but with concentrations far below the regulatory limits.

Description and consequences of variability in sows and piglets

Consulter le resumé

Nathalie Quiniou et al., 69th Annual meeting of the european federation of animal science (EAAP), Dubrovnik, Croatie, 27-31 août 2018

Even though animals are from the same genetic line, farmers have to cope with variability both in sows and piglets.
In sows, variability is observed in traits such as parity, prolificacy, appetite, body weight (BW) and back fat thickness (BF). For instance, at the beginning of gestation, variability in body condition among sows can be high due to parity and age. In addition, at a given age, variability in litter size, milk potential, and appetite results in different nutrient requirements and consequently in variability of changes in maternal body reserves. Variability in BF can be a problem as several studies have indicated that too high or too low BF values are to be avoided at farrowing as well as at weaning. In both cases, the longevity of the sow is impaired, and farmers are advised to manage the sows toward a target BF depending on the physiological stage, associated with an age-dependant BW, increasing with age up to mature BW. In addition, variation in sow’s body condition at farrowing and in prolificacy influences the new born and weaning piglet traits. Compared to less prolific sows, high-prolific sows farrow more piglets, which are both lighter on average and more heterogeneous. Compared to normal birthweight piglets, the survival rate of low birth weight piglets is lower. Providing additional care around birth helps these piglets to survive, but subsequent housing and feeding management have to be adapted to deal with the variability in their growth potential. Nutritional strategies (based on modelling approaches that take into account criteria that influence requirements) are suggested to optimise the expression of the animals’ potential, but most often without an intention to reduce inter-individual variability in growth performance. In order to control or reduce variability, other solutions have been evaluated in experimental studies that focus on the level and the dynamic of the feeding plan and the quality of the diet. The challenge is now to validate these solutions in production units, which will be more or less easy depending on the existing housing and feeding systems, and the economic, welfare and environmental context.

Relationship between age and body weight at farrowing over 6 parities in Large White × Landrace sow

When no information is collected on BW during the gestation, the expected final BW is also used to assess daily BW and corresponding maintenance requirement and to take into account impacts of housing conditions (temperature, activity level). Then, adequacy of the energy supply depends not only on initial and final BT, but also on initial BW and final BW.

Based on this equation, the individual expected BW gain (both growth and recovering parts) can be calculated and, combined with BT gain, used to assess the corresponding energy requirement for precision feeding during gestation. Its calibration for other lines or farms will require specific measurements due to interactions with management.
