Enterocin Ent7420 and sage application as feed additives for broiler rabbits to improve meat carcass parameters and amino acid profile

The effect of enterocin (Ent)7420 and sage on rabbit meat carcass quality and amino acid (AA) conetnt was evaluated. Ninty-six Hyla male rabbits (35 days aged) were divided into experimental: E (Ent7420), S (sage), E + S (Ent7420 + sage) and control (C) groups. The additives were administrated in drinking water during 21 days. Time and time and treatment interaction effect were noted on carcass traits. The highest protein level was noted in rabbits LTL receiving Ent7420 in combination with sage. Essential (EAA) and non-essential amino acid (NEAA) levels increased in all experimental groups, with the highest EAAs in group E + S (E + S vs. E, S: P < 0.01; E + S, E, S vs. C: P < 0.001) and NEAAs in group E (E vs. S, E + S, C: P < 0.001). The dietary inclusion of Ent7420 alone and in combination with sage can improve the rabbit meat quality due to its higher protein, EAAs and NEAAs profile.

Automated summary

The study evaluated the effects of enterocin (Ent)7420 and sage on rabbit meat quality and amino acid content. The results showed that combining Ent7420 with sage led to the highest protein levels in rabbit meat, as well as increased essential and non-essential amino acids in all experimental groups. Dietary inclusion of Ent7420 alone or in combination with sage improved rabbit meat quality.
