Abstract

Neurodegenerative disorders with or without behavioral disorders are constantly increasing. Support for affected patients is particularly complex due to the associated presence of several pathologies and social factors. The objective of doctors is to optimize the care of these elderly people. The use of lavender essential oil (Lavandula angustifolia) in this type of pathology is being studied as a treatment for cognitive disorders and behavioral disorders and which could help limit the iatrogenicity of psychotropic drugs.

Abstract

Early feeding in the nest is a promising biomimetic strategy to improve gut health and prevent digestive diseases. To formulate adequate starter feed, it is essential to determine the nutritional values of the preweaning diets. However, the assessment of suckling rabbits' digestion is challenging since the kits are raised together with their mother along with the fact that gut morphology and functionalities are deeply changing during the transition from milk to solid feed. To study the digestive capacity of the young rabbits, a 15-days digestibility trial was performed from 21 days of age to weaning on rabbits provided with early feeding or not. A mother-litter separate feeding system with controlled suckling was used to monitor intake and faecal excretion of 20 litters. All the litters had access to pellet feeds from 15 days. A starter feed in a form of a gel was provided as early as 3 days of age to half of the litters. Gut development dynamics and milk intake were taken into account to adjust faecal digestibility calculations. Digestibility coefficients of dry matter, crude protein, gross energy, and fibre fractions (NDF, ADF, Hemicelluloses) were high between 21 and 24 days (64%, 72%, 68%, 44%, 37% and 55%, respectively) and were followed by a decrease between 25 and 27 days (-16%,-10%,-16%,-32%,-37%,-7%). Starter feed supplementation did not modify faecal digestibility. Our original data revealed a short period where digestive capacity of the rabbit seemed to be overwhelmed by the sudden influx of dry matter in the gut. This could be implemented in the future for pre-weaning feed formulation.

Abstract

Postweaning short-term restriction strategies are commonly used in rabbit breeding to reduce mortality and morbidity. However, little is known about the implications of the immune system in that reduction. This work studied the consequences of feed restriction and dietary digestible energy (DE) concentration on the local immune response, according to a 2x2 factorial design: 320 animals were alloted at weaning (35 days of age) in four groups, with two diets differing in DE (10.13 vs 9.08 MJ DE/kg) and two intake level (ad libitum "AL" or restricted at 75% of AL). Ten animals per group and per age were sacrificed at 50 and 63 days of age. Feces, blood and ileum were collected. Fecal and plasmatic IgA levels were determined by ELISA and ileal cytokine expressions were measured by RT-qPCR. Fecal IgA levels were reduced by 58% with feed restriction (P

Abstract

Restricted feeding is commonly used in rabbit breeding to reduce mortality and morbidity but results in decreased growth and lower slaughter yield. A high energy diet offered at 75% of the ad libitum (AL) intake could prevent these detrimental effects. The aim of this work was to study the consequences of such a feeding strategy on the digestive efficiency of growing rabbits. 48 animals were divided into four groups differing in dietary energy content (2417 (HE) vs 2168 kcal DE/kg GM) and feeding level (AL or restricted at 75% (R)) according to a 2x2 experimental design. Animals were fed the experimental diets from weaning (35 d of age) to 74 d of age, and feed restriction was applied from 35 to 63 d. Digestive efficiency was assessed during feed restriction (42 to 46 d) and after one week of AL feeding (70 to 74 d). Feed restriction improved fecal digestibility of organic matter (OM, +3.8pts), protein (+5.4pts) and fiber (NDF +5.5pts, ADF +5.9pts; p

Abstract

National audience; L'effet de la teneur en protéines de l'aliment (T=147 vs HP=180g MAT/Kg) a été étudié sur la qualité de la carcasse et de la viande de lapins, nourris à volonté (ad lib.=100%) ou rationnés (R=75% de l'ad libitum) pendant 4 semaines à partir du sevrage (35j). La restriction alimentaire a réduit le rendement à l'abattage (-1.4 pt) et l'adiposité globale de la carcasse (note d'engraissement : -0.6 pt, gras interscapulaire : -27%, périrénal : -37%). La viande des lapins restreints présentait un pH ultime supérieur pour le râble (+0.3 pt). Les indicateurs de coloration de la viande (L*a*b*) ont révélé une viande plus pâle chez les lapins soumis au rationnement, tant au niveau du Biceps Femoris (Luminance : +0.87 pt et indice de rouge : -0.97 pt) que du râble (indice rouge : -0.68 pt et indice de jaune : -0.53pt). L'élévation du taux protéique de l'aliment a très légèrement augmenté le rendement à l'abattage (+0.3 pt) et a réduit l'adiposité de la carcasse (note d'engraissment : -0.2 pt, gras interscapulaire : -9%). La qualité du Biceps Femoris a été sensiblement modifiée par le taux protéique de l'aliment (pHu : -0.05 pt, indice de jaune : +0.68 pt).

Abstract

National audience; L'effet de deux stratégies de restriction de l'ingestion (-25% de 35 à 63j d'âge), avec distribution unique ou fractionnée en 2 (1D vs 2D), a été analysé sur le comportement alimentaire du lapin, sa digestion et sa qualité de carcasse. L’étude a été réalisée dans un réseau de 5 stations d’expérimentation cunicole (groupe GEC) et sur un total de 2444 animaux élevés en cages collectives. Le fractionnement de la distribution ne modifie pas la quantité d'aliment ingérée (121g/j en moy., 35-63j.). Sept jours après l'application du rationnement (42j.), le profil quotidien d'ingestion est profondément modifié, avec une consommation du tiers de la ration quotidienne de 8h30 à 10h30, contrairement aux témoins qui en ingère moins de 10%. La distribution fractionnée accroit l'ingestion du matin chez les lapins restreints (>40%), en revanche cela accroît l'ingestion "nocturne" chez les animaux nourris à volonté (85-90%). Les animaux restreints du groupe "1D" ont en moyenne consommé 90% de la ration avant 16H30. La distribution fractionnée n'interagit pas avec le niveau alimentaire sur l'efficacité digestive, cette dernière étant améliorée avec une ingestion réduite de 25% (+3 unités pour l'énergie, +6 pour les protéines, et +4 pour le NDF, P

Abstract

The transition from a milk-based diet to exclusive solid feeding deeply modifies microbiota-host crosstalk. Specifically, early ingestion of plant polysaccharides would be one of the main nutritional components to drive host-microbiota-interaction. To capture the effects of polysaccharides early-life nutrition (starch vs rapidly fermentable fiber) on the holobiont development, we investigated on the one hand the gut bacteriome and metabolome and on the other hand the transcriptome of two host gut tissues. Rabbit model was used to study post-natal co-development of the gut microbiota and its host around weaning transition. The assessment of the microbial composition of the gut appendix together with the caecum was provided for the first time. Gene expression signatures were analyzed along the gut (ileum and caecum) through high-throughput qPCR. The data collected were completed by the analysis of animal growth changes and time-series assessment of blood biomarkers. Those accessible and reusable data could help highlight the gut development dynamics as well as biological adaptation processes at the onset of solid feeding., (© 2024. The Author(s).)

Abstract

In mammals, the introduction of solid food is pivotal for the establishment of the gut microbiota. However, the effects of the first food consumed on long-term microbiota trajectory and host response are still largely unknown. This study aimed to investigate the influences of (i) the timing of first solid food ingestion and (ii) the consumption of plant polysaccharides on bacterial community dynamics and host physiology using a rabbit model. To modulate the first exposure to solid nutrients, solid food was provided to suckling rabbits from two different time points (3 or 15 days of age). In parallel, food type was modulated with the provision of diets differing in carbohydrate content throughout life: the food either was formulated with a high proportion of rapidly fermentable fibers (RFF) or was starch-enriched. We found that access to solid food as of 3 days of age accelerated the gut microbiota maturation. Our data revealed differential effects according to the digestive segment: precocious solid food ingestion influenced to a greater extent the development of bacterial communities of the appendix vermiformis , whereas life course polysaccharides ingestion had marked effects on the cecal microbiota. Greater ingestion of RFF was assumed to promote pectin degradation as revealed by metabolomics analysis. However, transcriptomic and phenotypic host responses remained moderately affected by experimental treatments, suggesting little outcomes of the observed microbiome modulations on healthy subjects. In conclusion, our work highlighted the timing of solid food introduction and plant polysaccharides ingestion as two different tools to modulate microbiota implantation and functionality. IMPORTANCE Our study was designed to gain a better understanding of how different feeding patterns affect the dynamics of gut microbiomes and microbe-host interactions. This research showed that the timing of solid food introduction is a key component of the gut microbiota shaping in early developmental stages, though with lower impact on settled gut microbiota profiles in older individuals. This study also provided in-depth analysis of dietary polysaccharide effects on intestinal microbiota. The type of plant polysaccharides reaching the gut through the lifetime was described as an important modulator of the cecal microbiome and its activity. These findings will contribute to better define the interventions that can be employed for modulating the ecological succession of young mammal gut microbiota.

Abstract

Early introduction of a nutritional substrate is a promising biomimetic strategy for controlling the implantation of the microbiota and preserving the health of young animals. In this study, we provided experimental solid substrate in a gel form to stimulate suckling rabbits' intake and to investigate its effects on microbiota implantation and colonization. All the rabbits had access to solid feed outside the nest as of 15 days of age. Except for the control group, rabbits were offered starter feed gels inside the nests from 3 to 18 days of age. These gels were either free of additives (AF&#95;GEL) or contained 4% of fructo-oligosaccharides (FOS&#95;GEL) or 4% of mannan-oligosaccharides and β-glucans mixtures (MOS&#95;GEL). The cecal content of 160 rabbits was sampled at 18, 29, 38, and 57 days of age and analyzed using 16S rRNA gene sequencing. Pups consumed an average of 3.95 ± 1.07 g of starter feed gel with a higher intake when it was supplemented with fructo-oligosaccharides (+1.2 g; P < 0.05). Starter feed gel consumption increased the ensuing intake of pellets (+17 g from 15 to 21 days; P < 0.05). Alpha-diversity indexes were similar between groups and prebiotic supplementation did not induce a clear shift in microbiota pattern. Conversely, when considering rabbits that consumed more starter feed, the highest proportions of bacteria with plant-degrading abilities, such as species from the Lachnospiraceae and Ruminococcaceae families, were observed at 18 days of age. However, fermentative activities were not affected by starter feed intake at 29, 38, and 57 days of age. By providing comprehensive results on the regulation of microbial community structure at the onset of solid feed intake, this research paves the way for further studies on digestive ecosystem maturation., (Copyright © 2020 Paës, Gidenne, Bébin, Duperray, Gohier, Guené-Grand, Rebours, Bouchez, Barilly, Aymard and Combes.)

Abstract

Weaning is a critical period for the health of rabbits, with a high sensitivity to digestive diseases. Allowing early consumption of solid feed in the nest of the suckling rabbit could help to maintain its health around weaning. In general, previous studies have focused on feed intake of rabbits when they are able to leave the nest, i.e. around 16 days. Herein, we provide a unique dataset of the dynamics of the onset of feed intake in suckling rabbits from 8 days to weaning. We quantified the solid feed intake behaviour and determined the dietary preferences for pellets according to their physical properties using nine pellets differing in diameter or compression rate. Additionally to the data provided in Paës et al. [1] we provide (i) the description of the nine pellets processing (ii) the description of the 3 point-scale system for nest quality evaluation, (iii) details on the device used to provide pellets in the nest, (iv) milk intake data and milk intake curve calculation and (v) pellet intake data according to physical characteristics., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2020 Published by Elsevier Inc.)

Abstract

Background: Short-term feed restriction strategies are used in rabbits to reduce postweaning digestive disorders, but little is known about the involvement of the immune system in these beneficial effects., Objective: In the present study, the consequences of feed and energy restriction on immune response were investigated., Methods: At weaning, 320 male and female rabbits were assigned to 4 groups differing in dietary digestible energy (DE) concentrations and intake levels: a low-energy ad libitum-feed (LE100) group, a low-energy restricted-feed (LE75) group, a high-energy ad libitum-feed (HE100) group, and a high-energy restricted-feed (HE75) group. The high-energy groups consumed 10.13 MJ DE/kg of feed, whereas the low-energy groups consumed 9.08 MJ DE/kg (formulated values). Intake amounts for the restricted groups were 75% those of the ad libitum groups. Rabbits consumed these diets until age 63 d, after which they consumed feed ad libitum for 9 d. Ten rabbits per group and per age were killed at ages 42, 50, 63, and 72 d. Spleens and appendixes were weighed; Peyer's patch surface area was determined by image analysis; plasma total immunoglobulin (Ig) G and anti-ovalbumin IgG; and fecal and plasma IgA concentrations were determined by ELISA; and ileal expressions of cytokines were measured by quantitative reverse transcriptase-polymerase chain reaction at ages 50 and 63 d., Results: The relative weight and size of the lymphoid organs were not affected by treatments. Concentrations of plasma total IgA (-41% at 63 d and -29% at 72 d), IgG (-22% at 72 d), and anti-ovalbumin IgG (-41% at 63 d) were lower with feed restriction. Fecal IgA concentrations were lower with quantitative restriction (-40%, -52%, and -65% at age 42, 50, and 63 d, respectively) and energy restriction (-56%, -46%, and -73% at ages 50, 63, and 72 d, respectively). Feed-restricted rabbits tended to have greater expressions of interleukin (IL) 1β and IL-2 and lower expressions of tumor necrosis factor α (P < 0.1)., Conclusion: These results demonstrated that, in rabbits, restriction and, to a lesser extent, dietary energy concentration modulate gut immunity., (© 2015 American Society for Nutrition.)
