Effects of Protein and Energy Balance in Ration on Physiological and Hematological Status of Garut Sheep

摘要

Background and Objective: The quantity and quality of rations play an important role in maintaining livestock performance. This relates to the energy produced which in turn can affect the physiological and haematological status. This study aimed to observe physiological status parameters (respiratory frequency, body temperature, heart rate and pulse) and hematologic parameters (erythrocytes, leukocytes, haemoglobin, haematocrit and platelets) of Garut sheep which are treated by different protein and energy balance. Materials and Methods: The study was conducted using 24 weaned Garut sheep, aged 4 months old, using a completely randomized design (CRD). The treatments given are P1 = ration with 12% protein content and 60% total digestible nutrients (TDN), P2 = ration with 12% protein content and 65% TDN, P3 = ration with 14% protein content and 60% TDN, P4 = ration with 14% protein content and TDN 65%, P5 = rations with 16% protein content and 60% TDN and P6 = rations with 16% protein content and 65% TDN. Results: The results showed that the energy and protein balance in each ration did not significantly affect the physiological and haematological status, except plasma leukocytes level and haematocrit of sheep. Sheep that provided ration with 14% protein content and TDN 65% (R4) had a significantly higher (p0.05) leucocytes and haematocrit level compared with other treatments. Conclusion: The provision of rations with a protein balance of 16% and TDN 60% is sufficient to meet the production needs of sheep in terms of physiological and haematological status in Garut sheep.
