- Abstract
Normal productive and reproductive behavior in domestic animal is closely associated with interaction between hormones and nutritional status of the animal system. A double PG protocol and dietary mineral mixture supplementation were used on 24 non-descript delayed pubertal heifers, aged between 3-5 years to study the effect of both on reproductive performance. Heifers were randomly allocated into four equal groups, comprising A (Control), B, C & D treatment groups (n=6 in each group). All the groups were fed iso-nitrogenous and iso-caloric ration according to the body weight. Group A (n=6) was fed a ration containing 0% mineral mixture feeding on a daily basis. Group B (n=6) received rations containing a mineral mixture at 1% of the total diet per day. Group C (n=6) was subjected for double PG protocol and GnRH. Group D (n=6) was fed a ration that included a mineral mixture @ 1 % of the ration, along with the double PG protocol and the GnRH. Compared to group C, group D has slightly higher progesterone levels due to more pregnant heifers. A significant increase in plasma progesterone concentration was observed in the B, C, and D groups that received mineral mixtures and hormone protocols. A similar progesterone level was found in group C and group A at 60 days. The estrogen value in group D was lower due to the higher number of non-cyclic heifers in comparison to the other groups. Additionally, mineral concentrations in the treatment groups were significantly higher than those in the control group. Group A, B, C and D were recorded 33.3, 50.0, 66.6, and 83.3% pregnancy rate respectively after artificial insemination, which indicating the effect of combining hormonal protocol with mineral mixture supplementation.
