“…Probably, the maintenance of feeding and rumination times associated with a reduction in the DMI has resulted in increased feed and rumination efficiencies for goats. Evaluating the replacement of whole grain corn with whole cassava root, Silva et al (2012) found no effect on the times and efficiencies of ingestion and rumination of dairy goats, as well as on the number of cuds and daily cud chews of the animals.…”

“…However, the whole root can also be used in ruminant feed when dehydrated (Chanjula, Ngampongsai, & Wanapat, 2007;Faria et al, 2011;Santos et al, 2015). For dairy goats specifically, the replacement of corn with cassava shavings improved the digestibility of non-fiber carbohydrates in the feed, but did not influence the animal ingestive behavior (Silva et al, 2012). However, due to the powderiness caused by the dry root and the difficulties in storage and cyanide toxicity of the fresh root, a viable alternative for the preservation of the cassava root is ensiling.…”

The objective of this study was to evaluate the effect of replacement of corn with pre-dried cassava root silage (CRS) on intake, ingestive behavior, production and composition of goat milk. Five lactating Saanen goats were used, with 42.5 ± 4.2 kg body weight and production of 2 kg milk day-1, distributed in a 5 x 5 Latin square with five treatments: 0, 28.6, 58.0, 81.6 and 100% replacement of corn with CRS in the diet dry matter. Goats were monitored for five periods of 15 days each. The intake of dry matter, crude protein and neutral detergent fiber decreased linearly (p <0.05) with the replacement of corn with CRS. Feeding (348.5 ± 62.1 min.) and rumination (468.8 ± 83.8 min.) times were not influenced (p >0.05) by the replacement of corn with CRS, but the ingestion and rumination efficiencies had a linear increase (p > 0.05). Milk production (2.17 ± 0.45 kg day-1), fat (3.49 ± 0.42%), protein (3.11 ± 0.13%) and lactose (4.47 ± 0,11%) of goat milk were not influenced (p >0.05) by the replacement of corn with CRS. Therefore, it is recommended the total replacement of corn with pre-dried cassava root silage in the diet for dairy goats with an average production of 2 kg day-1.
