Effect of @entity460 with and without probiotic, XXXX , or both on organ and body weights, immune response and caecal microbiota in moulted laying hens.

@entity742 @entity353 @entity1132 @entity460 @entity9495
UNASSIGNED: A total of 72 laying hens were used to investigate the effect of probiotic and @entity1132 on body @entity353 , tibia ash, antibody production against @entity742 red blood cell (SRBC), heterophile-to-lymphocyte (H/L) ratio and gut microbiota in a common moulting method for 14 d. Hens were randomly allocated to 6 experimental groups consisting of (i) full feed (FF), (ii) feed withdrawal (FW), (iii) FW with @entity460 ( @entity9495 ), (iv) FW with @entity9495 and offering 7  g/lit @entity1132 in drinking water (CaL), (v) FW with @entity9495 and offering 1  g/lit probiotic in drinking water (CaP), and (vi) FW with @entity9495 and offering a mixture of @entity1132 and probiotic in drinking water (CaLP). The results showed body @entity353 in all FW groups were more than 25% that was significantly higher than FF group (p  <  0.05). The relative organ weights of hens in FW groups were lower than FF group; especially, it was significant for liver and ovary (p  <  0.05). No significant difference was observed between all groups for tibia ash. The highest H/L ratio was related to FW group and offering @entity9495 and @entity1132 numerically and probiotic alone significantly resulted in decrease of this ratio (p  <  0.05). The results also showed no significant difference for antibody production against SRBC among experimental groups. The highest coliform bacteria numeration observed in FW group and @entity1132 could significantly reduce this population (p  <  0.05). Lactic acid bacteria (LAB) numeration demonstrated a significant difference among treatments, so that FF hens had higher LAB than others (p  <  0.05). In addition, FW moulted hens had significantly lower LAB compared to other moulted hens (p  <  0.05), except for @entity9495 group. In conclusion, probiotic and @entity1132 was effective in maintaining caecal microbiota balance and improving immunity in hens exposed to moulting.
