บทคัดย่อ (EN): Three experiments were conducted in Suratthani province. The First experiment was aimed at studying the chemical composition and dry matter degradability of palm oil and palm oil by-product and to apply this to feedstuffs for ruminants. The second and third experiments were conducted to study protein requirements for maintenance and growth of Southern indigenous cattle and Brahman crossbreed cattle fed palm oil by-products. The by –product from palm oil plantations were palm fronds (PF). By –product from the palm oil industry were: 1. decanter cakes, another source of energy (4175.5 kcal/kg) 10.79%EE and 14%CP for ruminant, 2. Palm kernel cakes (PKC) separated into two groups, pure PKC without shell or husk (containing 14.5%CP and 77.7% NDF) and PKC mixed with shell and husk (containing 6.8%CP, 59.3%NDF), 3. Empty fruit bunch (containing 3.4%CP, but high NDF and ADF contents), 4. Palm press fiber (containing 7% CP, high NDF (91%) and ADF (74%)). Dry matter degradability of the PKC and decanter cake were 60% and 62%, respectively. The second experiment studied the dietary nitrogen requirement of native Thai cattle. The relationship between the average daily gain (ADG) and N intake (NI) was: ADG = 525.22 NI – 92.29 (R2 = 0.32). The protein requirement for maintenance and growth 100 g of growing male indigenous cattle was 0.176 g N/kgW0.75/d and 0.06 g N/kgW0.75/d, respectively. The third experiment studied the protein requirements of Brahman crossbred steers reared under small-holder condition. The relationship between the protein intake and ADG was: protein intake= 0.578 x ADG + 5.686 (R2 = 0.94) showing protein requirement for maintenance was 5.686 g protein /kgW0.75/d (0.909 gN/ kgW0.75/d) and protein requirement for 100 g protein /kgW0.75/d growth was 57.78 g protein/kgW0.75/d (9.24 gN/ kgW0.75/d). This value is close to 58.98 g protein/kgW0.75/d, the requirement reported in WTSR (2008). The investigated nutrient requirement of the WTSR (2008) can be used for Brahman crossbred cattle reared under small-holder condition in Southern Thailand.
