Afegir etiqueta | Sumari: | Iron supplementation for newborn piglets is a standard practice in intensive swine production, due to the need to prevent anemia and ensure optimal development. Despite its importance, many producers underestimate iron supplementation, considering it an unnecessary expense, which can negatively affect animal health and productivity. Because of these challenges, the present research focused on the evaluation of different iron administration treatments in newborn piglets, using two forms: dextran and gleptoferron. The main objective was to evaluate the effects of different iron application treatments on hemoglobin levels and productive parameters in piglets. Additionally, the possibility of achieving similar results with lower doses of iron compared to the standard dose of 200 mg of iron dextran administered on the third day of life was explored, which could have important implications for efficiency and resource management on pig farms. The study was carried out at the Mathias pig farm, located in the Balsas canton, El Oro province. A stratified random sampling was performed using a completely randomized design (CRD), using a total of 150 piglets (females and males) distributed in five treatments (30 animals per treatment). Hemoglobin levels at day 20 showed significant differences among treatments (p<0.05), with values ranging from 11.02 g/dL (T3 the lowest) to 11.90 g/dL (T5 the highest). As for hematocrit, significant differences were also observed (p<0.05), with values ranging from 32.46 (T3 the lowest) to 35.06% (T5 the highest), at the same age as the animals. In the results obtained for the variable weight gain, no significant difference was found between treatments (p˂0.05). |
