During the re alimentation period greater ADG

During the re-alimentation period, greater ADG was observed in the restricted group compared to control group. Greater ADG during the re-alimentation period, after early dietary restriction, was reported by Daza et al. (2003) and Serrano et al. (2009). Daza et al. (2003) reported that SB273005 compensatory growth response was observed 4 and 5 wk after the restriction period. The results from studies to restrict AA in the diet are inconsistent. Some authors (Kamalakar et al., 2009 and Martínez-Ramírez et al., 2008) observed no differences in ADG after early AA restrictions, but Fabian et al. (2002) reported greater ADG after early dietary Lys and other AA restrictions. During the re-alimentation period, greater G:F was observed in the restricted group compared to the control group. This is in an agreement with other studies (Daza et al., 2003, Fabian et al., 2004 and Serrano et al., 2009). In spite of the fact that there was greater ADG in the restricted group after early dietary restriction, we assume that a formation of fatty tissue was predominant in pigs exhibited compensatory growth. Similarly, other authors reported that greater ADG during the re-alimentation period is due to a greater fat deposition (Bikker et al., 1996 and Skiba et al., 2004). The pigs after early dietary restriction retained more fat in the body in comparison to non-restricted animals (Lovatto et al., 2006).
