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.

They are also high in amino acids...which are very important for muscle building and maintenance.
Here is a good article on BOSS for goats but still informative:
The sunflower seed is a great source of quality protein, vitamins and minerals.
It has particular high quantities of thiamine and niacin. It's main mineral ingredient is iron, which is a difficult nutrient to obtain in sufficient quantities.
Feeding Sunflower Seed May Prevent Enterotoxemia By George F. Haenlein, University of Delaware, College of Agricultural Science, reprinted from Dwarf Digest, Summer 1998
Enterotoxemia is one of the major problems in dairy goat husbandry. The usual preventive treatment is vaccination against the offending clostridial perfringens microorganisms with bacterin toxoid type C and D at least twice annually. However, enterotoxemia is also known as overeating disease or toxic indigestion. It occurs after excessive feed intake by baby kids and adult goats especially when feed is very palatable; when the animals are hungry; when they stuff themselves with concentrate feeds, shelled corn, oats, oil meals and pellets, and when the feeds don't have long fibers.
However, nature made a neatly packaged feed which is palatable to goats without being too palatable, and which as a highly nutritious content inside its very useful fiber wrapper. This is the suflower seed. It was not routinelyavailable commercially in this country until recent consumer interest developed in sunflower oil, in shelled, salted or toasted sunflower seeds in natural food store snacks, and in sunflower seeds for winter wild bird feeding.
The bulk density of sunflower seeds is much less than for the other seeds, which might be another advantage against overeating disease; it takes more time for goats to eat 1 lb. of sunflower seeds than to eat 1 lb. of shelled corn.
However, due to the very high fat content of sunflower seeds, exceeding even soybeans, the total digestible, metabolizable and net energy contents for lactation are even higher than for oats and are not much less than for corn or soybeans. The mineral contents of sunflower seeds are higher than for corn; for calcium, phosphorus and potassium, sunflower seeds are much higher than either corn or oats; and the protein content is much higher than for corn or oats.
The main value of sunflower seeds, to date much overlooked in the nutrition and management of dairy goats - of dairy cows, too - is the high fiber content without sacrificing energy, mineral and protein values.
Black oil sunflower seed is good for them and helps with glossy coats. Goats like the whole sunflower plant if they can get it. However, if you are milking goats, it can suppress their milk.
