Effect of intestinal conditioner pronutrients compare to zinc oxide in weaned piglets
Effect of intestinal conditioner pronutrients on productive parameters and the adaptation to the new diet in weaned piglets, compared to the use of zinc oxide.
WeaningÂ is a critical point of the pig production cycle, as it is an stressful moment for the animals, caused by the combination of several factors from nutritional, social and environmental origin, among others, which may cause the appearance of intestinal disorders and a decrease in feed intake and weight gain.
Several products have been commonly used, together with management measures, to control intestinal disorders at this stage, like antibiotics and zinc oxide. Nowadays, the limitations stablished by the regulations make farmers search for alternative solutions to control the presence of diarrhea at weaning, like the use of intestinal conditioner pronutrients.
This trial evaluated the effect of intestinal conditioner pronutrients on productive parameters and the adaptation to the new diet in weaned piglets, compared to the use of zinc oxide.Â
A total of 600 piglets were used for this trial. Animals were 21 days-old at the beginning of the trial and 84 days-old at the end of the trial: 42 days of the nursery/postweaning phase, and 21 days of the fattening period.
Animals received the products during the nursery period (21 to 63 days old), and the assessment of productive parameters was performed during nursery and early fattening (63 to 84 days old), to see if there were long-term effects.
Animals were distributed in 2 groups:
- T1 – ZnO: Received zinc oxide from weaning (21 days) till day 42 of age at 2,5 â€“ 3 kg/t.
- T2 â€“ Conditioner: Received intestinal conditioner pronutrients from weaning (21 days) till day 63 of age at 0.5 kg/t.
The table below shows similar weight and ADG were obtained in both groups, without significant differences between T1 and T2.
Despite this, the group fed the conditioner (T2) obtained better FCR (3.47% improvement), which was significantly different in the last days of the nursery stage (days 21 to 42 of the trial).
The positive effect of the conditioner remained visible in the fattening stage, after the usage of the product.
The trial demonstrates that intestinal conditioner pronutrients can replace the use of zinc oxide in the nursery stage.
In addition, the use of the intestinal conditioners showed a positive impact in the following stages, thanks to a better gut development during the post-weaning period.
Furthermore, as pronutrients are a natural plant-based solution, they are safe for the environment and for human and animal health, as they avoids the secondary impact that zinc oxide has as a contaminant of the soil and the risk of resistances.
