Adición de la harina de limón mandarina (Citrus x limonia) sobre los índices productivos e inmunoglobulinas en cerdos (Sus scrofa domesticus) post destete

Abstract

The main objective of this research was to evaluate the addition of Mandarin lemon (Citrus x limonia) flour on productive indices and IgG and IgA immunoglobulins in post-weaning pigs. Four treatments were employed: Control Treatment (T0) without addition of flour; T1: with 0.1%; T2: with 0.2%; and T3: with 0.3% (Citrus x limonia). We used 24 post-weaning pigs of Landrace x Yorkshire crossbreed, 28 days old with initial weights ranging from 5.4 to 6.4 kg. They were distributed into 4 treatments with 6 repetitions each one, with one animal per repetition, using a completely randomized experimental design (DCA). Data were analyzed using ANOVA and Tukey's test at a significance level of 95%, with the statistical software Infostat 2020. The duration of the research work was 28 days, during which weights were recorded at 35, 42, 49, and 56 days of age. Subsequently, blood samples were taken from the jugular vein and sent to the laboratory to determine the levels of serum immunoglobulins IgG and IgA using the immunoturbidimetry technique. No significant results were obtained regarding productive indices in the first three weeks. However, in week four, it was demonstrated that there was a better weight gain ratio and a more favorable feed conversion ratio for T0, while T3 had a higher weight gain and feed conversion ratio, making it the least favorable. In immunology, results were obtained for T0 in IgA and for treatment T2 in IgG. Additionally, a lower incidence of digestive disorders was observed due to antioxidant and immunomodulatory properties.
