Title: Effect of Parity on Live Body Weight, Daily Milk Yield and Lactation Length of Sudanese Kenana Cattle
Author: Elamin, Khalid M.
Abstract: Effect of parity (PA) on live body weight, daily milk yield and lactation length of Sudanese Kenana cattle breed were investigated using a surveyed random sample comprised of (200) animals on different numbers of parities, animals were reared on natural pastures. All parameters were determinated by standard statistical analysis models with multivariate ANOVA when daily milk yield (DMY), Live body weight (LBwt) and lactation length (LL) as response and parity numbers (PA1, PA2, PA3 and PA4) as independent (P≤0.05). The results revealed that parities had a significant effect on all quantitative parameters that investigated. These differences between observed means were separated using Duncan multiple range tests with equal variances assumed. This suggests that parities could be used as independent factor for estimation of quantitative parameters with relatively high accuracy in Sudanese Kenana cattle breed.
