Macadamia integrifolia

Macadamia nut, Queensland nut

Evergreen tree native to eastern Australia and also extensively cultivated in Hawaii and California. The nuts have a smooth round shell measuring about 2 cm in diameter. The shell splits when the kernel is ripe. The kernels contain 75-80% oil, which would make a good salad oil, but the kernels are too valuable as dessert nuts for commercial milling.

Feed-grade macadamia nuts can be included up to 10% in concentrates for ruminants without adverse effects. Higher levels in ruminant feeds decrease feed intake and digestibility because of the high fat content of the nuts.
