ThesisItem Open Access Comparative study on Ravenna grass (Saccharum ravennae) in relation to retention of foetal membranes in bovines(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Himanshu Kumar; Gupta, H.P.The present research work was organized for comparative study on ravenna grass(Saccharum ravennae) in relation to retention of foetal membranes in bovines. Thirty six primiparous and pluriparous recently calved crossbred cows without the history of dystocia were selected for the study and divided into five treatment and one control group as T1, T2, T3, T4, T5 and C. Cows in T1 group were given 2kg bamboo leaves, orally once after mixing with jaggery. Whereas cows in group T2, T3 and T4 were given green ravenna grass @ 50, 150 and 300gm, orally, single dose respectively. A single dose of methylergometrine maleate @ 5mg IM was given to cows in T5 group. All treatment was given immediately after parturition. Cows in control group were left untreated. Cows were examined for expulsion of foetal membranes and onset of first postpartum visible estrus. The mean time of expulsion of foetal membranes in groups T2, T3 and control was significantly (p˂0.05) higher than the groups T1, T4 and T5. The mean time (days) for first postpartum visible estrus was significantly (p<0.05) short in T1, T3, T4 and T5 as compared to control group. On day 0, glucose concentration was significantly (p˂0.05) low in control as compared to T1 and T5. In T1, T2, T4, T5 and control group, the significant (p˂0.05) increase in the blood glucose concentration was observed between day 0 to 30 and 45 postpartum. In T1, T2, T3, T4, T5 and control group, there was a significant rise in the total protein level from day 0 to 15, 30 and 45. Significantly (p˂0.05) lower calcium level in blood was observed in T2 and control as compared to the T1, T4 and T5, on the day of calving (day 0). Significantly (p˂0.05) lower phosphorus level in blood was observed in control group as compared to the T1, T4 and T5, on the day of calving (day 0). In group T1, T3 and T5, the concentration of selenium was significantly increased from day 0 to 30 and 45 postpartum. While, in the T4 group, the concentration of selenium was significantly increased from day 0 to 15 postpartum. In the control group, the zinc concentration was significantly increased from day 0 to 15, 30 and 45 postpartum. The finding from the present study suggests that there is no effect on hemoglobin, TLC and DLC concentration by different treatment protocols. Ravenna grass is also play an important role to prevent the case of RFM as similar to methylergometrine maleate and bamboo leaves.
