Use of a bacterial complex on the surfaces of farrowing and post-weaning rooms: impact on digestive health and growth performance of piglets

Consulter le resumé

Use of a bacterial complex (Lactic acid bacteria and Bacillus ; Cobiotex ®) in farrowing and post-weaning units and benefits on digestive health and growth performance of piglets.

Suckling and weaning are difficult periods for piglets; they are more prone to infections e.g. diarrhea and arthritis. Therefore, room hygiene and the management of biofilm are essential, however, they are not always easy to control. The use of a bacterial complex (Lactic acid bacteria and Bacillus; Cobiotex ®) was studied in farrowing and post-weaning units. Two farrowing rooms and two post-weaning rooms with the same configuration were used in an experimental farm, one treated and
the second as control. The complex was applied on the surfaces of the rooms after cleaning, disinfecting and drying and it was repeated regularly (each week) during the life cycle of the animals. The piglets' performances during lactation and after weaning were measured and the health criteria were estimated: mortality, digestive health by scoring the consistency of faeces, arthritis and observations of clinical signs. Results in farrowing stage - The percentage of weaned piglets did not differ between the 2 groups. The percentage of arthritis, although lower in the treated room was not significantly different. Fecal scores were significantly lower in the treated group at 4 days: 17% of the treated group piglets with diarrhea against 41% in the control group. This difference is not confirmed at 21 days, perhaps due to the very low prevalence of diarrhea at this stage in the two groups (less than 2%). Weight gain per litter in the treated room was higher (100 g / day) than in the control room, but this difference was not significant. Results in post-weaning stage - The percentages of mortality between the two groups were not significantly different. Fecal scores 7 days after weaning showed significantly less diarrhea in piglets of the room treated: 56% of piglets had "normal" faeces against 45% in the control room. Fecal scores 14, 21 and 28 days after weaning were not significantly different. During the first fourteen days post weaning, the average daily gain and feed conversion ratio were
significantly improved. They were not different for the period from 14 to 35 days after weaning. Conclusion - The bacterial complex, after its spraying in the whole surface of a livestock building, promoted optimal digestive health (assessed by fecal score) during the suckling and post-weaning periods. The post-weaning growth performances during the first age (ADG and FCR) were significantly improved.

Application d’un complexe bactérien sur les surfaces des salles de maternité et de post‐sevrage : impact sur la santé digestive et les performances de croissance des porcelets

Consulter le resumé

Les périodes d’allaitement et de sevrage sont deux phases délicates pour le jeune porcelet, avec notamment des infections digestives et des arthrites (Anses, 2013). Les conséquences peuvent être des baisses des performances de croissance, des mortalités et le recours aux antibiotiques (Hémonic et al., 2013). La maîtrise de la pression d’infection en particulier par une hygiène rigoureuse des surfaces et par la lutte contre le biofilm fait partie des mesures préventives précédemment décrites (Madec et al., 2008).

L’utilisation de complexes bactériens pour orienter la flore bactérienne de surface des salles et stabiliser l’écosystème bactérien afin d’éviter le développement de flores pathogènes, en complément d’un nettoyage‐désinfection rigoureux, est une alternative à évaluer.
