Effect of diet forms and litter types on the productive traits of broiler (Sasso) [electronic resouce].

Includes references.

This experiment was conducted to investigate the effect of the different form of diets and litter types on the productive traits of broiler (Sasso). A total number of 1890 one day old chicks of Sasso broiler were used. The study included nine groups of treatments, with two replicates for each treatment (18 pens); in factorial experimental design( 3X 3) three diet forms (pellet, mash and crumble) by three types of litters (sand, wheat straw and wood shaving litters). Results of Sasso broiler live BW at eight weeks of age, shows significant differences (P ≤ 0.05) was recorded among litter types and highly significant (P ≤ 0.001) among feed forms treatments. In that chicks fed diets of pellets or crumbs forms has highly significant superiority values over the chicks fed that of mash form through the 8-week. Also a highly significant difference (P ≤ 0.001) was attained with feed forms during period of 1-56 days of age. However, the differences among litter types of wheat straw or wood shaving in that respect were insignificant. FCR during the whole experimental period ranged between 1.69 (g feed/g gain) for the birds raised on wheat straw litter and fed pellet diet and 2.01 (g feed/g gain) for the birds raised on wheat straw litter and fed mash diet. Mortality rate of birds fed mash form diet was lower than those fed pellet or crumble form diets throughout experimental period. The performance index (PI) during the whole experimental period ranged between 54.43% (mash x wheat straw group) and 64.43 % (pellet x wheat straw group) for all combination groups studied. The Production number (PN) ranged between 375.91 (wheat straw x crumbs group) and 491.45 (wheat straw x pellet group) for all combination groups studied. The chicks fed pellet forms had significant superiority score over the chicks fed crumbs or mash forms, since the Profit margin (PM) averaged 7.33, 4.90% and 2.90 % respectively. Also, chicks raised on sand litter recorded highly significant highest PM at marketing age compared with chicks raised on wheat straw or wood shavings litters (8.79, 4.73 and 1.62 respectively). Key Words: Diet Forms, Litter Types, Productive Traits, And Broiler (Sasso).
