Full textTo limit health disturbances is a challenge for the pig industry. The objectives of this study are to quantify the feed intake and growth responses of pigs following different sanitary challenges, to describe the adaptive dynamic responses of pigs to common farming practices in combination with the sanitary conditions, and to determine the consequences of a feed restriction on these adaptive responses. For major health disturbances that may occur in commercial pig production settings, feed intake and growth responses were quantified by a meta-analysis using data of 122 peer-reviewed experiments. The intensity of these responses differed among sanitary challenges, suggesting differences in the physiopathological mechanisms implied. The reduction in growth is partly due to a reduction in feed intake but also due to changes in digestion and metabolism. The contribution of changes in digestion and metabolism to the response was most prominent for sanitary challenges that directly affected the gastrointestinal tract. In the experimental part of this study, farming practices of feed restriction after weaning and building changes had short-term negative effects on performance, health status and behavior of pigs irrespective of the sanitary conditions. In poor sanitary conditions, the negative consequences of feed restriction worsened in the course of time. The degradation of sanitary conditions, as its interaction with feed restriction, led to an increase in the time to recover the level of performance and behavior observed before the building change. The results of this study are a first step to taking into account health factors in predictive growth models such as InraPorc®. These models can be used tools to test strategies supporting the adaptation of the animal to its environment. Key words: weaned pigs, health, nutrition, adaptation, meta-analyzis

Full textThis study aimed at evaluating nutritional strategies that could modify the rate and composition of weight gain at both whole body and muscle levels in pigs, and therefore increase age and intramuscular fat (IMF) content at slaughter without increasing carcass fatness. Two nutritional strategies were used : 1) 25 % restricted feeding (R1) or 20 % energy restriction associated with a progressive decrease in lysine to energy intake (R2) from 30 u^to 110 kg in both synthetic line (experiment 1A) and Duroc (experiment AB) crossbreeds, 2) compensatory growth (CG) response following a feed restriction during the growing period : 30 up to 80 kg followed by re-alimenatin up to 110 kg in Duroc crossbreeds, experiment 2 ; 35 % restricted feeding from 30 u^to 70 kg followed by re-alimentation up to 110 kg in Duroc crossbreeds, expirement 3. In experiment 1, R1 and R2 pigs were 30 d older at slaughter, due to a 25 % lower growth rate compared with ad libitum controls. At 110 kg, R1 pigs were leaner and had less IMF, whereas R2 pigs exhibited a similar carcass composition, but higher IMF content as compared with controls. The increase inf IMF was high and highly significant in the Longissimus, in particular for the Duroc crossbreeds (+ 40 % IMF, P<0. 001), but was not significant in the Biceps femoris muscle of both genotypes

Full textWeaning is a critical step in pig farms. Separation from the sow, change in the environment and dietary transition from liquid milk to a solid diet induces a destabilization of digestive and defense functions in weaned pig. Weaning leads to digestive disorders and growth alteration that often require antibiotic use to alleviate pathogen invasion and mortality. Bacterial resistance to antibiotics has become a major concern for public health. Thus, it has become necessary to find new strategies to promote digestive health in weaned pigs. The aim of this thesis is to evaluate the potential of two microalgae – Spirulina and Chlorella – as new functional ingredients to promote digestive health in piglets at weaningTwo trials were conducted in pigs weaned in contrasted sanitary conditions –good or poor–and that received 1% of Spirulina or Chlorella in starter diet. In good sanitary conditions, dietary supplementation with Spirulina and Chlorella both enhanced nutrient digestibility and intestinal morphology but did not affect growth performance. In poor sanitary conditions, both Spirulina and Chlorella supplementation altered growth performance with slight effect on indicators of digestive health. In a third trial, oral administration of the two microalgae before and after weaning was assayed to evaluate the ability of Spirulina and Chlorella to limit the early intestinal changes caused by weaning. Spirulina administration before and after weaning enhanced growth in suckling piglets and reduced risk of diarrhoea outcome in weaned pigs. Potential mechanisms of action of Spirulin

Full textL'excrétion endogène basale d'azote est en moyenne de 1.14 g/kg MSI. L'animal en est le principal facteur de variation.
En moyenne, la DIV de l'N des céréales se situe entre 77% pour le seigle et 87-89% pour le blé, le triticale, et le maïs. Celle des issues de meunerie passe de 94% pour les farines basses à 70% pour les sons. Celle du corn gluten feed varie de 62 à 75%, selon le lot. Elle est de 74% pour le tourteau de colza, 81 % pour le tourteau de tournesol et 88% pour le tourteau de soja. La DIV des AA des issues de meunerie, du corn gluten feed et du tourteau de soja peut être prédite à partir de leurs teneurs en fibres insolubles et/ou du pourcentage d'azote lié au résidu NDF (NNDF).
En moyenne, l'excrétion endogène spécifique d'N se situe entre 1.1 et 2.1 g/kg MS pour les céréales. Elle est de 3.6 et 7.9 g/kg MS pour, respectivement, le tourteau de soja et le tourteau de colza. Pour la plupart des matières premières, l'excrétion endogène spécifique d'N augmente significativement avec la teneur en fibres insolubles. Toutefois, plus l'animal est léger, plus il semble sensible à une augmentation de la teneur en fibres insolubles, et en particulier en ligno-cellulose, du régime. Par ailleurs, la fibre de type blé serait plus stimulante que la fibre de type orge. Des équations de prédiction de l'excrétion endogène spécifique d'N en fonction de la teneur en ADF (Acid Detergent Fibre) du lot de matière première et du poids de l'animal sont proposées.
En moyenne, la DIR de l'azote est supérieure à 95% pour le blé, le triticale et le maïs, elle est de 94% pour le tourteau de soja, 91 % pour le sorgho, 88% pour l'orge, 84% pour le seigle et 86% pour le tourteau de colza.
