PORTILLO, Guido Arnaldo; RENAUT AQUINO, Juan Eusebio  and  SILVA MAZACOTTE, Elva Estefani. Effects of the use of α-amylase and lipase enzymes on the productive performance of recently weaned piglets. Investig. Agrar. [online]. 2021, vol.23, n.2, pp.111-116. ISSN 2305-0683.

During weaning, piglets have low digestive capacity due to the limited secretion of the enzymes responsible for digesting feed, affecting their productive performance, making it necessary to supplement with enzymes exogenously. For this, twelve non-castrated recently weaned and undefined breeds’ male piglets were used with the objective of evaluating the effects on productive performance of the use of α-amylase and lipase enzymes. The experimental design of randomized blocks was used, with three treatments (T1: control, T2: α-amylase and T3: Lipase) and four repetitions. The data were submitted to ANAVA and the means were compared by Duncan's test (p <0.05). It was verified that the piglets supplemented with α-amylase and Lipase presented greater weight gains (LWG and DWG) during the trial, as well as for the total LWG and the average DWG and in the DFI they stood out in the second and third period (30 and 45 days) and in the average DFI; while in the FC they only stood out in the two initial periods (15 and days) and in the average FC, while in the evaluation carried out at 45 days, the treatments presented similar behaviors for this variable. It is concluded that the addition of α-amylase and lipase enzymes in the feeding of weaned piglets is effective as they improve feed consumption, feed conversion and consequently weight gain and it is recommended to supply up to 30 days post-weaning.
