“…Once the animals received the feed formulated for the kits, the difference in feed intake levels disappeared. It was previously demonstrated that this behavior led to a higher weaning weight with no negative effect on kit health (Read et al, 2016). An explanation could be the higher appeal of starch, as the energy in the mothers feed was supplied in the form of starch.…”

“…The introduction of solid feed is a key step in the development of intestinal microbiota and young rabbit specific feed has to be designed to stimulate solid feed ingestion and promote the maturation of the bacterial community. Read et al (2015, 2016) have previously shown that the feeding strategy at the onset of solid feed intake influences the early feed ingestion, where feed high in energy had a positive effect on early feed intake (Read et al, 2015, 2016), health and growth (Read et al, 2015). In this study, we compared the common rabbit feeding strategy in which young rabbits have the same feed as their mothers until the age of 28 days with a strategy of introducing from 18 days of age either a high concentrate or low concentrate feed that will be offered to young rabbits after weaning.…”

This study aimed to evaluate how the feeding strategy of rabbit kits at the onset of solid feed intake could affect ecological diversity and co-occurrence patterns of the cecal bacterial community. From birth to 18 days of age kits were exclusively milk-fed, and between 18 and 35 days the young rabbits also had access to solid feed. After weaning at (35 days), young rabbits were exclusively fed solid feed. Three experimental feeds were used: a high concentrate diet [H: 10.16 MJ digestible energy (DE)/kg and 15.3% crude protein (CP)], a low concentrate diet (L: 9.33 MJ DE/kg and 14.7% CP) and a reproductive female diet (R: 10.57 MJ DE/kg and 17.3% CP). The rabbit kits ( n = 357) were divided into three groups, differing by the diet received during two periods: from 18 to 28 and from 28 to 49 days of age. In the groups LL and HH, rabbit kits were fed L or H diets, respectively, during both periods. Kits in the group RL received feeds R and L from 18 to 28 and 28 to 49 days of age, respectively. Cecal bacterial communities of 10 rabbits per group were carried out at 18, 28, 35, 43 and 49 days of age by MiSeq Illumina sequencing 16S rRNA encoding genes. Between 18 and 28 days of age, solid feed intake was higher in the group RL compared to the other two groups (+24%; P < 0.01). Overall, 13.4% of the OTUs detected were present in the cecal ecosystem from 18 to 49 days old, whereas 17.4% were acquired with the onset of solid feeding and kept from 28 days on. Exclusive milk consumption constrains the bacterial community toward a similar structure but high phylogenetic beta-diversity. Introduction of solid feed induced a sharp change of microbial community structure and decreased phylogenetic diversity. A strong relationship in bacterial community network occurred only from 43 days on. Our feeding strategy at the onset of solid feed ingestion exhibited only a moderate effect on the microbial community structure ( P = 0.072), although the LL group seemed to reach faster maturity compared to the two other groups.

“…The rabbits were fed according to the diet established for each treatment. The food required was provided in two daily rations, according to their age: at 7:30 am in the morning, and at 4:30 pm in the afternoon because according to Read et al (2016), although rabbits have a limited feeding behavior, they can consume pelleted food quickly, which generates a hunger state during part of the day, creating stereotypical behavior to famine and the frustration for not consuming forage.…”

Nutritional supplementation with non-conventional food resources and its effect on the productive parameters in rabbits

The effect of diets with nonconventional forage resources, balu (Erythrina edulis) and giant taro (Alocasia macrorrhiza) was evaluated, on production parameters of New Zealand white rabbits (Oryctolagus cuniculus) under family farming production, in Silvania (Cundinamarca, Colombia). 36 weaned rabbits of 35 days old were used. They were distributed in 4 treatments (substitution of commercial pellets by giant taro leaves flour 25% (Giant taro), balu 25% (Balu); their mixture, giant taro 12.5% and balu 12.5% (GB), and a control with commercial pellets) with three repetitions each. Variables evaluated: initial weight at 35 days old, daily weight gain, consumption, feed conversion and final weight at 85 days old, carcass yield, haunch, loin and meat. Data was analyzed by Tukey multiple comparison test at 5% significance level, variance homogeneity and error independence verified by means of Shapiro-Wilks, Levene and Durbin-Watson tests, respectively, by R program. No significant differences were found in the final weight, on weeks 5 and 6, which registered significant differences (p<0.05), for giant taro (1771.85±88.21 AB), control (1933.06±88.20 B), giant taro (1935.05±91.26 AB), control (2144.42±91.26 B) respectively. Daily weight gain showed significant differences (p<0.05) at week 5 for giant taro (33.56±2.82 AB); control (.37±2.825 B). Significant differences were showed by most zootechnical variables (p<0.05). The results showed that diets with nonconventional forage resources (balu and giant taro) are a viable alternative for animal feeding, due to their high nutritional content and as a by-product of commercial interest for rural families in areas of the middle Colombian tropics.

“…Alimentation mère-jeune séparée Un autre moyen de stimuler l'ingestion solide est de favoriser l'accès à l'alimentation dès que le lapereau est en capacité de quitter le nid, sans modifier l'âge au sevrage, à l'aide d'un logement et de mangeoires adaptées (Fox et Guthrie, 1968 ;Fortun-Lamothe et al, 2000 ;Mirabito et Bocquier, 2005). Développé dans un cadre expérimental, ces dispositifs d'alimentation mère-jeune séparés, ont permis de préciser le comportement nutritionnel des jeunes (Debray et al, 2002 ;Travel et al, 2009 ;Read et al, 2016) mais n'ont pas été adopté en élevage commercial (figure 1). L'une des pistes de recherche pour la mise au point d'un aliment spécifique lapereaux encore allaités est de fournir au microbiote caecal un substrat à base de fibres rapidement fermentescibles, afin de stimuler son implantation et l'activité digestive, dans le but de l'amener plus vite à un état stable apte à surmonter le stress du sevrage.…”

Pour des lapereaux plus robustes au sevrage : des bases biologiques aux leviers d’action en élevage

et al. 2018

Les lapereaux naissent nus, incapables d’assurer seul une thermorégulation autonome suffisante, et ne sont qu’en partie mature sur les plans sensoriel, physiologique et moteur. Leurs interactions avec la mère sont limitées. En élevage, dès qu’ils sont capables de sortir du nid, ils accèdent à l'aliment de la lapine, bien qu’ils aient des besoins nutritionnels différents des siens. Face à ces apparentes fragilités, l’espèce a développé des adaptations physiologiques et comportementales efficaces comme l’existence de la phéromone mammaire, le comportement coprophage au nid et la dynamique de maturation du système digestif, qui sont autant d’atouts contribuant à la viabilité et robustesse des lapereaux au sevrage. Nous présentons ici certains leviers d’action envisageables en élevage (gestion des nids, homogénéisation des tailles et poids de portée, allaitement contrôlé, alimentation spécifique) pour valoriser ces atouts.
