Effects of Katuk Leaf (Sauropus androgynus L. Merr) Meal Supplementation on Physiological and Hematological Status of Peranakan Etawah Goats

The study aimed to determine the effect of supplementing katuk leaf meal in concentrate on physiological and haematological status of Etawah grade goats. The research took place at the Goat Breeding and Forage Production Installation Sumlili Village, West Kupang district of  Kupang Regency, from March to August 2024. The materials used were 12 heifers of Peranakan Etawah (PE) goats with body weight of 21.5 – 25.3kg, mean 23.4 ± 1.85kg; rations were forage (lamtoro) and concentrate. The study used a 4 x 3 completely randomised design (CRD), with four treatments tried, namely: P₀ = farmer’s pattern ration of lamtoro leaves + 300g concentrate (70% fine bran: 30% ground yellow corn) without katuk leaf meal; P₁ = P₀ + 5% DM forage; P₂: P₀ + 10% DM forage; P₃= P₀ + 15% DM forage. The observed variables were respiration rate, pulsus rate, rectal temperature, haemoglobin content, erythrocyte count, erythrocyte and haematocrit numbers. Data were analysed according to the variance analysis procedure. The results of statistical tests showed that the treatment had no significant effect (P>0.05) on all variables observed. The average results obtained were respiration rate 63.5 beats/minute; pulsus rate 81.08 beats/minute, rectal temperature 38.16°C, haemoglobin level 10.3 g/dL; erythrocyte count 11.12 x10⁶/mm³; leucocytes 10.3 x 10³/mm³ and haematocrit number 31.0%.  It was concluded that supplementation of katuk leaf meal in concentrate did not interfere with metabolism in PE heifers under conditions with indications of physiological and haematological status within normal ranges.
