Sažetak
To understand variability and phenotypic association among body traits in West African Dwarf goats, morphological traits were examined based on location and sex. Two hundred and twenty-seven (227) goats in two Nigerian states were surveyed. Randomized complete block with Factorial treatment design, GLM, Pearson’s phenotypic correlation procedures of SAS® was employed. Morphological and index traits examined were body weight (BWT), hearth girth (HGH), diagonal trunk length (DTL), height at the withers (HWT), height at the rump (HRP); and Trunk length index (TLI), over-building index (OBI), body depth index (BDI), body breath index (BBI), withers-girth index (WGI), body-length index (BLI)and Weight-height index (WHI). BWT, DTL, TLI, OBI, BLI and WHI were influenced (P<0.05) by location, while DTL, TLI, OBI, BDI, BBI and BLI were influenced (P<0.05) by interaction of Location and Sex. Does recorded higher (P<0.05) BWT, TLI and BLI (27.75, 183.62 and 156.33), while Bucks had higher (P<0.05) DTL, HGH, HWT, HRP, OBI, BDI, BBI, WGI and WHI (80.57, 58.78, 46.89, 46.36, 99.29, 126.01, 127.01, -26.02 and 45.83). Ekiti goats recorded higher OBI, while Osun goats were higher on DTL, TLI, BLI and WHI (P<0.05). Highest correlation for females and males were between BWT/WHI (r =0.952/0.967, P<0.0001); for BWT/WHI were (r =0.969/0.972, 0.0001); and between HRP/HWT (r =0.953/0.929, P<0.0001) on Ekiti and Osun goats respectively. Between Ekiti and Osun goats BWT/WHI (r =0.969/0.972, P<0.0001) and HRP/HWT (r =0.953/0.929, P<0.0001) were obtained. CVs were highest on WGI (-69.65/-45.16); BWT (31.89/43.79), and WHI (29.25/35.54) for Does and Bucks; while WGI (-56.72/57.42), BWT (53.51/46.78) and WHI (42.09/36.76) were higher for Ekiti and Osun goats. Significant (P<0.0001) phenotypic correlation were obtained between BWT, DTL, HWT, HGH individually, and many other traits (r =0.336-0.957).
