Partial substitution of @entity2247 for XXXX : effect on "Hamra" lamb growth performance, carcass and meat characteristics.

@entity4336 @entity2247 @entity742 @entity460
UNASSIGNED: The aim of this study was to investigate the effect of two kinds of given diets on growth, on some carcass characteristics and on the major meat nutrients of local Algerian @entity742 breed. The investigated @entity742 breed called "Hamra" is one of the most famous breeds in Algeria. Among one 106 animals, 40 @entity742 were selected according to their age, similar livestock characteristics and body weight. The samples were divided into two equal groups: control and experimental @entity742 according to their live weight; 24.63        0.47 and 24.35        0.64  kg, respectively. Both groups were fed with two varieties of concentrate diets: @entity4336 diet based for the first group of control @entity742 (n   =   20) and @entity4336 substituted by @entity2247 (Variety Sa  da 183) for the second experimental group @entity742 (n   =   20). Both diets were supplemented with 200  g straw of @entity2247 /animal/ration. The chemical analysis of diets showed an elevated crude fibre content in the commercial concentrate. However, the experimental concentrate contained higher amounts of @entity460 . After 59  days of fattening, no significant difference was found among the two studied groups on the growth performance (p   >   0.05), showing the same final body weight. In contrast, a significant difference was found (p    <=   0.001) in relation to the cost of the given diet. This could affect the price of the produced meat. At 37.85        0.78  kg live weight, 10 @entity742 fed with experimental concentrate were slaughtered. The dressing percentage was 46.65  %, with 2.49  % of carcass shrink. Furthermore, an interesting percentage of total muscle was obtained (63.73  %) with a good carcass conformation scoring 9.56. Compared to other breed @entity742 , Hamra carcass could be considered as the most valuable one economically.
