Performance of dairy goats fed whole sugarcane

Abstract

Five lactating goats were used in a 5x5 Latin square experiment to determine the effects of feeding whole sugarcane (WSC) on intake, total tract nutrient digestibilities, milk yield and milk composition. Goats were fed diets containing 0, 100, 200, 300, and 400 g kg(-1) WSC and 400, 300, 200, 100, and 0 g kg(-1) tifton hay (TH). Intake of dry matter and neutral detergent fiber (NDF) decreased linearly (p<0.05) as the level of WSC in the diet increased. Total tract nutrient digestibilities were not influenced by WSC inclusion except for the digestibility of NDF which decreased linearly (p<0.05) as the level of WSC in the diet increased. Inclusion of WSC linearly (p<0.05) decreased milk yield without affecting milk composition. It was concluded that WSC had a lower feeding values than TH for lactating goats.

Cana-de-açúcar em substituição ao feno de capim-tifton 85 em rações para cabras Saanen

“…Segundo Cabral et al (2008), o baixo CMS de dietas à base de cana-de-açúcar pode estar relacionado à baixa digestibilidade da FDN, o que certamente ocorreu neste estudo. Houve uma redução de 37,50% no CMS para dieta com cana-de-açúcar como volumoso único em relação à dieta exclusivamente com feno de tifton, e a baixa digestibilidade da FDN apresentou relação direta com o CMS.…”

Nutritional value of sugarcane silage enriched with corn grain, urea, and minerals as feed supplement on growth performance of beef steers grazing stargrass

“…Rumen degradable and undegradable nitrogen (Aranda et al 2001), as well as low fiber digestibility (Cabral et al 2009), are limiting factors in the utilization of sugarcane by ruminants. However, in our study the addition of corn grain and urea to the sugarcane maybe allowed higher starch and degradable N in the rumen (Alvarez and Preston 1976) to satisfy the needs of rumen microorganism and then improve the DM intake (OrtizRubio et al 2007).…”

“…However, due to the critical situations of sugar table industry and the low sugarcane crop price, it was induced that whole sugarcane plant be used as forage supplement for feeding cattle. Whole sugarcane contains around 29 g crude protein/kg dry matter (DM; Cabral et al 2009). When fresh sugarcane is used as supplement, the reduction of DM intake and neutral detergent fiber (NDF) digestibility is evident, which may be by the rumen acid pH caused by soluble sugar fermentation (Aranda et al 2001) or by the low NDF digestibility of sugarcane as compared to grasses (Cabral et al 2009).…”

Thus, this crop in the tropics is usually supplemented with richer nitrogen-protein ingredients (Gendley et al 2009).…”

Sugarcane‐derived animal feed

“…Whole sugarcane (i.e., stalk, juice, tops, and trash) is used extensively in the tropics and subtropics as a roughage source for the production of cattle , Hulshof et al 2012, Pedreira et al 2012, Rotta et al 2014, pigs (Xande et al 2009(Xande et al , 2010, sheep (Magana et al 2009, Cutrim et al 2012, and goats (Cabral et al 2009). Although not for human consumption, it is interesting to note that sugarcane (either processed using cryogenic grinding or pelleting) has been assessed as an additive to the diets of mice (Wang et al 2007(Wang et al , 2012 and cats (Fischer et al 2012) to improve their digestive and, hence, general health.…”
