Effect of coriander and anise as feed additives on growth and carcass characteristics of fattening buffalo calves [electronic resource]

Includes references.

Twenty-one six months old male buffalo calves weighed in average 110 kg were randomly divided into three groups (7animals each). Animals in group I (GR,) fed nonexperimental ration (control), while animals in group2 (OR,) and group3 (GR,) were fed rations with 4 kg Iton of concentrate feed coriander or anise as feed additives, respectively. Three animals of each group were slaughtered at the end of the feeding trial which lasted 240 days. The results showed that live body weight of calves in GR\was insignificantly higher than that of animals in GR, and GR,_ Dry matter intake of calves fed rations supplemented with coriander and anise were insignificantly higher than that of control group. The dressing percentage calculated relative either to slaughter weight (SW) or empty hody weight (EBW) was higher for calves in GR, than other groups. In similar trend meat yield percentage relative to SW or HeW had the highest values for calves in GR2_ Meat of calves in GR2 had higher juiciness, aroma and palatability in comparison to those of GRI and GR3• Cooking loss was higher for meat of calves in ORl than of GR2 and GR3. It was obvious that. feeding coriander supplement improved the boneless meat (BM) / slaughter weight (SWl, honeless meat BM / hot carcass weight (HeW), meat: bone ratio, water holding capacity, tenderness and eye muscle area than control group (ORl ) .It is fair to recommend the coriander as a natural supplement at 4kg Jton concentrate feed to improve meat yield and meat quality of buffalo calves.
