Activity 2.2. Evaluation of new feeding alternatives to allow early weaning Highlights • Supplementing pre-weaned calves with legumes during the dry season results in more milk for sale and higher liveweight gain compared with calves grazing a sole cropped grass pasture. 72
Jorge Vela IIAP, Peru Use of Stylosanthes guianensis for Strategic Supplementation of Pre-Weaned Calves in the Peruvian Amazon In the region of Pucallpa, in the Peruvian Amazon, milk price is very high due to a captive market of fresh milk. Pre-weaned calves usually consume between 15%-20% of milk production from dam (residual milk). Therefore, developing a feeding alternative to partially substitute the milk consumed by pre-weaned calves with a high quality legume could have a great impact on the income of smallholders because they could sell more milk and improve their cash flow. Materials and Methods The following treatments were evaluated: T1, access of calves to native grass pastures during 8 hours/day, together with dam, and the remaining 16 hours in a pasture of Stylosanthes guianensis + residual milk; T2, access of calves to native grass pastures 24 hours/day, without the presence of the dam + residual milk + concentrates; and T3, control (access to native grass pasture 24 hours/day + residual milk). Results Table 1 presents trial results. Average daily weight gain of calves grazing stylo pastures were similar those obtained in the traditional pasture management system, but milk sales increased by 23% (0.89 kg additional milk/cow per day). This was reflected in a 25% increase in income. The treatment with sylo + concentrate presented similar milk sales to those of the treatment without concentrate, but higher daily weight gains. However, the variable cost was also higher, resulting in similar total net incomes as when only stylo was used. Conclusions This improved feeding alternative can have significant impact on the quality of life of small farmers. Stylo can be used to replace concentrates and thus increases cash flow and income, as well as milk productivity without sacrificing a reduction in weight gain of pre-weaned calves. 73
