Feeding Value of Sugarcane Stalk for Cattle
Kawashima, T.,Sumamal, W.,Pholsen, P.,Chaithiang, R.,Boonpakdee, W.,Kurihara, M.,Shibata, M. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.1
A metabolism trial with four castrated male Brahman cattle, average body weight 320 kg, was conducted in order to determine the nutritive value of chopped sugarcane stalk (CSS) for the establishment of feeding strategy in the dry season in Northeast Thailand. Animals were subjected to the following four dietary treatments: Treatment 1; 100% of CSS, Treatment 2; 70% of CSS and 30% of commercial complete feed (TMR), Treatment 3; 40% of CSS and 60% of TMR, and Treatment 4; 100% of TMR. The average CP, ether extracts, nitrogen free extracts, crude fiber and ash contents of CSS were 2.0, 0.9, 79.0, 16.1 and 2.2%, respectively. Although the amount of feed given was approximately at maintenance level, animals in treatments 1 and 2 refused a part of feed. The metabolism trial revealed that total digestible nutrient and metabolizable energy contents of CSS were 61.5% and 9.04 MJ/kgDM, respectively, when it was properly supplemented with protein sources. Nutritive value of CSS was lowered when animals were given CSS solely. This was due to the large loss of energy into urine and methane. Voluntary intake of CSS in cattle was not enough to satisfy energy requirement for maintenance. The CSS can be used as a roughage for feeding cattle in the dry season with proper supplementation of protein and energy.
The Use of Sugarcane Stalk for Feeding Lactating Cows
Kawashima, T.,Sumamal, W.,Pholsen, P.,Chaithiang, R.,Boonpakdee, W. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.2
The use of chopped sugarcane stalk (CSS) as a roughage for lactating cows was examined using four Holstein crossbred cows in a private dairy farm in Khon Kaen, Thailand, in comparison with rice straw (RS), which is the conventional roughage in the dry season in the region. Cows were subjected to the following two dietary treatments: Diet 1) RS with commercial concentrate feed, and Diet 2) CSS and RS with commercial concentrate feed. The diet was switched over every 3 weeks. The amount of concentrate was determined by the experience of the owner of the cows. RS and CSS were given ad libitum. There was no difference in milk production between two groups, although the total DMI was less in cows fed CSS. Solid-not-fat (SNF) content in milk was significantly higher in the cows given CSS. The NEFA content was significantly lower in the animals given CSS, which suggested that cows given only RS as roughage would be suffering from energy malnutrition. Therefore, it was considered that CSS feeding improved energy supply, which resulted in higher SNF in milk. In the nutritional point of view, the present study clearly showed CSS can be used as a roughage for dairy cows in the dry season.
