The present research seeks to evaluate the use of a phytobiotic in the fattening phase of guinea pigs (Cavia porcellus) by predicting its impact on weight gain, feed consumption and feed conversion. A predictive model based on linear regression was developed to estimate the benefits of the phytobiotic. The guinea pigs that received the supplement showed a significant weight increase (1040.30 g compared to 967 g in the control group), as well as an improvement in feed conversion. This study suggests that the use of phytobiotics is a viable alternative to antibiotics, improving both productive efficiency and sustainability in guinea pig farming.

This study evaluated the effect of a phytobiotic as anutritional supplement in Novogen Brown laying hensduring the first laying stage at I.E.S. Publico Huando(Huaral). Two groups were established: one withconventional feed (control) and the other supplementedwith the BIO AVIPLEX GOLD® phytobiotic. Parameterssuch as weight gain, laying percentage, and economic meritwere analyzed for 20 weeks. The group that received thephytobiotic achieved a higher average laying percentage(70.18%) compared to the control (63.32%), and greateraverage weight gain (1449 g vs. 1409 g). Economic meritwas 12.06% in the treatment and 4.69% in the control.The Wilcoxon test confirmed statistically significantdifferences. In conclusion, the phytobiotic significantlyimproves productive performance and profitability inlaying hens, offering a sustainable alternative to antibiotics.
