| الوصف: | This study aimed to evaluate the effects of concentrate supplementation containing different protein levels on estrous signs and progesterone profiles of two age groups of Ongole Grade cow. Thirty females cows were grouped according to their ages (G1= 25±1.6 months; G2= 37±1.7 months), where each group received 3 dietary treatments with 5 replicates. The dietary treatment was based on CP levels of total mixed ration (TMR) (T1= 7.41% CP; T2= 8.23% CP; and T3= 9.17% CP). The cows were synchronized using PGF2α and GnRH, followed by time-fixed artificial insemination (TAI) using frozen semen. Data on nutrient intake and progesterone concentration were subjected to a randomized complete block design of ANOVA following a factorial arrangement of 2×3 while data of estrous signs were analyzed using non-parametric methods of Kruskal-Wallis and independent t-test. The results showed that there was a significant interaction effect between age group and dietary TMR treatment on CP intake and TDN intake in which the highest intakes were found in older cows (G2) fed TMR at 7.41% CP (T1) (p |
