Abstract
Various combinations of cereal chaff and Pinus radiata needles were fed to penned sheep in three experiments. The in vivo digestibility of green needles was estimated to be 36%. Intakes of needles were variable and increased to more than 50% of the total dry matter intake if the chaff component of the diet was restricted to 25% of normal intake. Under these conditions, the needles made a useful contribution to the diet and reduced rates of liveweight loss.The feeding value of pine needles may decrease by about 30% as they age but that of fresh young needles can be greater than those of late summer pasture residues. Therefore, if kept ungrazed for in situ consumption in summer or during drought, when pasture residues are not able to maintain sheep, green pine needles can be valuable either as a substitute for pasture or as a partial supplement.
