Black Oil Sunflower seeds are valued for their oil content, which accounts for about 50% of the seed dry weight. Boss is an excellent protein source 16-20% and Sunflower protein is less rich in the amino acid lysine than soybean protein but it does have a relatively high amount of the amino acids cystine and methionine. BOSS has a lot of omega oil which is good for animals fur coats and helps feathers shine and stay healthy. BOSS is more readily eaten by chickens than flax seeds. The oil that adds fat to their diet and helps their weight will make feathers glossy and shiny. This is important because the oil on the feathers will help keep their bodies insulated against cold and dampness.
It has also been said that black oil sunflower seeds play a large role in egg production. If you have hens that aren’t laying like they used to, try adding sunflower seeds to give them a productivity boost. You should not only see a boost in the number of eggs laid, but also the quality, making sunflower seeds a worthwhile addition to your chickens’ diet. Even if you don’t see a change in the egg production of older hens and ultimately decide to cull, you will see an increase in their weight beforehand.
A Brazilian study found increased egg weight in hens fed sunflower seeds. Its researchers stated that increasing levels of sunflower seeds in daily rations did not affect feed intake, feed conversion or yolk color.
Sunflower seeds contain 31% more iron per gram than raisins, another popular source for iron.
Overall, sunflower seeds are a good source of a number of important nutrients.
