Utilización de suero lácteo como suplemento en la dieta para lechones y su efecto en el crecimiento de vellosidades intestinales.

Abstract

This research aimed to evaluate the effect of intestinal hair growth using whey as a supplement in the diet of piglets. The methodology was carried out with a mixed focus (quantitative-qualitative), supported by bibliographic research. There were 12 piglets divided into three groups of 4. The first group was fed only with a commercial balanced feed (2kg); the second group was administered a balanced feed of 70% (1.4kg) and whey (30%) (6L); and the third group was offered a balanced feed of 60% (1.20 kg) and 40% of whey (8L). The results showed that the chemical characteristics analyzed from the whey were 5.055% sugars; 4mg/100g calcium; 0.534% ash; 13.2 mg/100g phosphorus; 0.5% fat; 91.983% humidity; 1.718% protein; and 45.862 mg/100g sodium. The acidity determined an initial pH of 6.32 with an acidity of 0.63. In the evaluation of the productive parameters with respect to the feed consumption in weeks 2 and 3, the T1 demonstrated statistical differences from the T3. With the diets about weight gain, T2 was the best, with 36.50%. For consumption, it was the T1 with 108.08%, while according to feed conversion, the T1 treatment was at 3.19%. No representative numerical differences existed between the values found as to the height and width of the hairs; however, there is variation in terms of the depth of the lowering to the reference value for the individual T2 and T3 concerning to T1 and to the initial value, where the microns doubled, concluding that the best treatment used was the T2.
