The effect of paddy straw and concentrate containing green tea dust on performance and nutrient digestibility in feedlot lambs

Abstract: The utilization of low-input paddy straw hay (PSH) for fattening lambs should be incorporated with a high-quality concentrate (HQC) in which green tea dust (GTD) rich in tannins can be added as a natural feed additive. Completely randomized design was used to compare 5 doses of GTD inclusions (dry matter, DM basis) at 0% (GTD-0), 0.5% (GTD-0.5), 1% (GTD-1), 1.5% (GTD-1.5), and 2% (GTD-2) in an HQC as the main diet of PSH-fed fattening lambs on average daily gain (ADG, g/head/day), dry matter intake (DMI, g/hea… Show more

“…In addition to the preference for other farm animals because of their ability to tolerate extreme environments, sheep productivity is an important part of rural farmers' lives, providing them with a source of animal protein and revenue from sheep trades [3] Traditionally, West Java's farmers have fed their local sheep with grass as the majority feed using a cut and carry method. Nowadays, farmers feed their sheep with not only grass as the main feed but also concentrate [4]. The typical concentrate ingredients are the by-products of agroindustry such as rice bran, cassava meal, copra meal, palm kernel meal, and so on.…”

“…The nutrient contents of the field grass can be seen in Table 1. Dry matter, ash, crude protein, crude fiber, and crude oils analyses were done using the method of the Association of Official Analytical Collaboration (AOAC, 2005) while total digestible nutrients (TDN) was calculated using a similar TDN equation to Ramdani et al (2020). Gross energy was measured using a bomb calorimeter.…”
