Effect of Cassava Hay in High-quality Feed Block as Anthelmintics in Steers Grazing on Ruzi Grass

Abstract

Six, one-year old dairy steers were randomly divided into two groups according to a Completely randomized design (CRD) to receive high-quality feed block (HQFB) without cassava hay and drenching (HQFB1+Ivomex) and HQFB with cassava hay (HQFB2) as block licks while grazing on Ruzi grass pasture. During the eight weeks, fecal parasitic egg counts dramatically declined for both treatment groups with 63.2 and 27.6% reduction from initial period for HQFB1+Ivomex and HQFB2, respectively. However, digestion of coefficients of nutrients particularly OM, were significantly higher in HQFB2 than, those in HQFB1+Ivomex, in addition, ADG of animals in HQFB2 tended to be higher than the group on HQFB1. It was, hence concluded that cassava hay could not only provide as a protein source but also serve as an anthelmintic in ruminants.

Effects of various plant protein sources in high-quality feed block on feed intake, rumen fermentation, and microbial population in swamp buffalo

“…Wanapat and Khampa (2006) reported that supplementation of HQFB could increase feed intake, nutrient digestibility, and rumen VFA. Moreover, supplementation of HQFB in lactating dairy cow indicates that rumen ecology, milk yield, and milk composition were significantly improved (Koakhunthod et al 2001).…”

“…The use of cassava hay was successfully implemented in several ways by either direct feeding or as a protein source in concentrate mixtures (Kiyothong and Wanapat 2004), as component with soybean meal and urea in feed supplements (Wanapat et al 2006a), and as an ingredient in high-quality feed blocks (Wanapat and Khampa 2006).…”

Effect of feeding feed blocks containing different levels of urea calcium sulphate mixture on feed intake, digestibility and rumen fermentation in Thai native beef cattle fed on rice straw

“…Therefore, to improve the productive and reproductive capacity of ruminant animals on small-holder farms, there is a need to develop feeding strategies that will enhance the quality and availability of feed resources (Calabrò et al, 2008;Wanapat, 2009). Feed blocks are solidified mixture of unconventional feeds such as rice bran, molasses, binder, salt, mineral and 10-15 g/kg DM of urea which have been shown to improve production of ruminants fed a rice straw as a main roughage (Wanapat and Khampa, 2006;Foiklang et al, 2011). However, inclusion of high amount of urea in the feed blocks is still limited because of the rapid hydrolysis of urea to NH 3 -N and absorption from the rumen (Galo et al, 2003).…”

Effect of Superblock Supplementation to Native Grass Based Diet on Rumen Fermentation In Vitro

“…However, the main principle of the supplement is to provide principal nutrient for microbial activity such as minerals, protein and soluble carbohydrates. Some study on feed supplement using by-product materials were reported by Roza et al (2013), Wanapat & Khampa (2006), Suharyono et al (2014) and Firsoni & Suharyono (2008). Indonesia national nuclear energy agency (BATAN) using tracer-radioisotope ( 32 P) technique previously reported that the formulation of agricultural and food by-products has resulted in feed supplement for ruminants.…”
