SUMMARY:

The performance in the first week after weaning piglets can interfere in the final performance of the animals. This period is a critical stage for the production systems and it is a challenge for the piglet. The aim of this study was to evaluate the use of an oral glycoelectrolytic supplement to reduce or repair the energy deficit and the dehydration of the animals, evaluated the intestinal integrity of piglets in the post-weaning period and analyze the economic viability (BRL) of the supplement. The sample consist of in a total of 240 Agroceres PIC piglets (castrated males and females) which was weaned at age 22.60 ± 1.10 days and have average initial weight of 6.30 ± 1.0 kg. The treatment was performed offering water to the control group (n=120) and the treatment group (n=120) received the oral glycoelectrolyte supplement diluted in water (0.75%) which was available in accessory troughs during the first three days after weaning. The experimental design was randomized blocks with 12 replicates per treatment and 10 piglets per replicate. The zootechnical parameters were evaluated as feed intake, daily weight gain, feed conversion and mortality rate at 3, 7 and 49 days after weaning. Blood glucose analysis was performed on all piglets and the erythrogram analysis for 12 piglets of each treatment. Statistical analysis was performed using the Software R® version 1.0, 2021. The sample normality and equality of variances was tested by Shapiro-Wilk and Levene´s test, respectively. The means were compared by the Student's t-test using. P-values <0.05 were considered statistically significant. The partial results showed a better feed conversion (1.29) and a higher fluid consumption (0.639 L/day) on the third day after weaning to the treat group when compared to the control group (P<0.05). Furthermore, the final weight of the supplemented piglets was 0.720 kg higher than controls, which economically represented a gain of R$ 4.24/piglet. Blood glucose, mean corpuscular volume and mean corpuscular hemoglobin showed higher values for the group of supplemented piglets (P<0.05) and the chance of developing diarrhea was similar between groups. In conclusion, the use of an oral glycoelectrolyte supplement 0.75% may be an option for piglets in the first days after weaning, due to improves feed conversion and fluid consumption, in addition to increasing blood glucose levels without the development of diarrhea.
