Feeding Value of Sugarcane Stalk for Cattle

Feeding value of cottonseed meal for feedlot cattle.

One hundred twenty crossbred steers (294 kg, initially) were used in a 141-d finishing trial. Four concentrations (8, 16, 24, and 32% of diet DM) of cottonseed meal (CSM, prepressed solvent-extracted) replaced steam-flaked corn in a corn-based finishing diet. Increasing level of CSM decreased ADG (linear component, P < .10), feed efficiency (linear component, P < .01), and dietary NE (linear co...

Fat Quality and Feeding Value of Fat for Feedlot Cattle

While much attention has been directed at understanding factors influencing the NE value of supplemental fat (Zinn, 1994), alterations in NE do not necessarily form the basis for constraints on supplementation. Indeed, greater concern is often directed at potential detrimental effects of supplemental fat on diet acceptability and feed intake (Brethour et al., 1957; BuchananSmith et al., 1974; C...

Available Methods for Assessing Varietal Resistance to Sugarcane Stalk Borers

Sugarcane is semiperennial and produces considerable biomass, forming an ideal habitat for insects. Most insects do not affect crops, but some compete with humans for sugar and by-products. Sugarcane stalkborers are key pests of this crop worldwide because they feed directly on the vegetative tissues that store sucrose, allowing the introduction of micro-organisms that affect yield and quality....

Modelling the Water Content of the Sugarcane Stalk

This study models the amount of water stored in the millable stalk as a function of the dry weight of the stalk structures and of the stored sucrose. The correlation was highly significant (r=0.98, n=30). Structural material was equated to the difference between the stalk total dry weight and sucrose. Knowing the effect of the water deficit on the water content of the cane, the deficits were co...
