Many factors complicate ruminal fistulation and cannulation by conventional methods and various modifications in the processing of ruminal cannulas as well as fistulation techniques had been recorded to minimise complications. Some studies investigated the effects of rumenostomy on physiological parameters, this study assessed changes in vital or physiological parameters following three different incision patterns of one-stage rumenostomy in Yankasa-Balami Ram. Nine healthy rams divided into three groups (A, B and C) were investigated for the effect of stylized (different incision locations on the rumen and skin) rumenostomy incisions on rectal temperature, pulse rate, and respiratory rates. These parameters were recorded before anaesthesia as preliminary values (Pre). Following anaesthesia and rumen cannulation, samples were collected at 0 h, days 1, 2, 3, 4, 5, 6 and similarly at weeks 1, 2, and 3. The Mean ± SE rectal temperature 37.56±0.42, 38.80±0.05, 38.26±0.18, pulse rate 72.00±1.15, 75.33±1.76, 76.00±3.05 and respiratory rate 23.33±2.90, 22.00±3.05, 24.33±1.85 were established at Pre for groups A, B and C respectively. All these parameters remain within the control values throughout the study except for group B where significant increase in pulse rate (97.66±0.88) was observed after surgery and subsequently returned to normal at day 1, while that of A and C are 83.00±2.88 and 80.33±2.18 respectively. The significant decrease in respiratory rate (17.00±0.57, 14.66±0.66, 15.33±0.88 for A, B and C respectively as well as decrease in temperature (35.00±0.06, 36.03±0.14 and 36.50±0.28 for group A, B and C respectively were observed. Normal pulse rate (78.33±2.02, 77.66±2.18, 79.33±2.33 for group A, B and C respectively), respiratory rate (20.00±0.57, 20.33±0.66, 21.00±1.52 for A, B and C respectively and temperature 38.03±0.29, 38.66±0.06, 38.73±0.06 for A, B and C were recorded at day 1. Additional incisions in group B resulted in more bleeding, which could have caused additional physiological stress. Overall, the more invasive procedure performed on group B likely resulted in a greater degree of physiological stress compared to the other groups, which may explain the observed differences in heart rate, respiratory rate, and rectal temperatureResults from the analyses show that the proposed scheme is highly effective and can withstand any statistical and brute-force attacks.
