Track 1-15: Pastures in Integrated Crop/Livestock Production Systems
Description
Fluctuations in commodity prices, determine the need to find strategies to stabilize production in farming systems. The rice - pastures rotation systems are a good example of this, where animal production takes place in the moments where rice is rotated with pastures (3 years rice and 2 years pastures). In this context, INIA has developed a technology adjusted to the east of the country, with the use of "summer tillage" to intensify livestock production through the incorporation of lambs fattening. These technologies, comercially validated with sheep-rice farming systems, can move the process of cattle backgrounding (males and females), but requires technological adjustments related to planting winter annuals species and the strategic use of the supplementation and subsequent evaluation of the impact of these proposed intensifications of the livestock production phase and subsequent rice production. There are now new tools to study the feasibility of these alternatives (productive and economic) through modelling, but the validity of their results will be based on the certainty of technical coefficients. These coefficients must be generated in real situations where all the factors interact (Deambrosi 2009).
The objective of the present experiments, was to com-pare livewieght (LW) per hectare, daily gain (DG) and weight gain (WG) per animal on an annual ryegrass (‘LE 284’) sown over rice stubble, used for calf backgrounding, under the effect of two stocking rate, in the north of Uruguay.
