The Effects of L-Arginine Supplement on the Growth Rate and Morphometric Performance of Three Indigenous Strains of Birds

This study investigated the effect of supplementary L-Arginine on growth rate and morphometrics three indigenous strains chicken. A total 297 12-week-old pullets comprising 99 Kuroiler, Sasso, Shika Brown each. 3x3 factorial trial was used each treatment replicated thrice. There were levels oral inclusion (0.00mg, 500mg, 1000mg/3000ml water) for replicate respectively. Morphometric data measured body weight (BW), back length (BL), breast girth (BG), comb height (CH), shank (SL), thigh (TL), wattle (WH), (WaL), wing (WL). The linear measurements showed no significant (p>0.05) differences. However, birds administered with a higher (1000mg) dosage arginine had nominally metric values compared to other treatments. Kuroiler measures among breeds. These comparable Sasso but differed from which least measures. Observed trends that morphometric traits interaction between 1000nmg administration than any combinations. reversals deviations above-reported trend in breed BW, BG, SL while similar.
