Rough rice

Many birds such as sparrows, blackbirds, rice birds, grackles, and cowbirds can cause heavy loss of grain in rice fields. Because the use of poisoned baits in some countries is often restricted by law or popular opinion, the information presented does not constitute a recommendation on any specific chemical. The use of strychnine-poisoned rough rice (17, 18, 25) against blackbirds, grackles, cowbirds, and English sparrows, wherever the use of poison is permitted, can be effective. Many other toxic chemicals will kill these birds however, domestic poultry and game bird species are relatively much less susceptible to strychnine than to other toxic materials. Therefore, we have in strychnine a fairly effective selectivity which other toxic materials do not offer. 

The findings reviewed by El Boushy and van der Poel (2000) indicate that wheat and sunflower seeds, polished rice, cooked potatoes, potato flakes and fresh fish are very palatable feedstuffs. Oats, rye, rough rice, buckwheat and barley are less palatable, unless ground. Linseed meal appears to be very unpalatable. 

Rough rice (paddy or padi rice) can be used in poultry diets after grinding but is generally not available. Rice that does not meet the quality standards for humans after processing is a good feed ingredient for poultry diets, provided it is not moulded and contaminated with toxic fungi. 

Harvested rice grain is composed of the outer hull, the bran layer and the inner white starchy endosperm. Rough rice, which is rice with the hull intact, is the form in which rice is stored for use throughout the year. Removal of the hull produces what is known as brown rice. Once the hull is removed, inadvertent scratching of the inner...

Rice oil is a minor constituent of rough rice when compared with the carbohydrate and protein content. Two major classes of lipids are present those internal within the endosperm and those associated with the bran. The internal lipids contribute to the nutritional, functional, and sensory qualities of rice (7). 

In developing countries, most rice is milled in a one-stage (huller) mill that removes hull, bran, and germ as a single mixture. It is estimated that less than 25% of rough rice is fractionated into hull and bran fractions (29). 

Parboiling of rice is also an example of wet heat stabilization. The lipase in rough rice is completely inactivated by either autoclaving for 3-20 minutes or by parboiling. 

The rough rice or paddy undergoes a precleaning process prior to milhng. Foreign materials, such as stones, mud baUs, straw, and weed, are separated with the use of screens, aspirators, and gravity separators. Cleaned rough rice is then...

Rice harvested from the plant with its husk intact is known as rough rice or paddy. The husk is not eaten by humans but is sometimes burned for use as an energy source.

Milling of rice is different from that of some of the other cereals in that there is usually no grinding step to produce a powder. Milling involves removal of the hull and bran layers of the rough rice kernel (paddy). Hulled rice (brown rice) is composed of surface bran (6-7% by weight), endosperm (about 90%), and embryo (2-3%). Milling of brown rice uses abrasion and friction between kernels to produce polished or whitened rice, where some 8-10% of the mass (mainly bran) has been removed.
