Britain doesn't have much of a goat-eating culture, but it's a different story elsewhere: globally, it's a major protein source, not least because goats are far easier to raise than sheep.
Prices have since leveled off, and soybeans continue to be a major protein source for many countries - especially prized by vegetarians around the globe for nutritional value and versatility in recipes, ranging from tofu burgers to soy smoothies.
A study was conducted to determine the effects of replacing canola meal (CM) as the major protein source with wheat-based dried distillers grains with solubles (W-DDGS) on ruminal fermentation, microbial protein production, omasal nutrient flow and animal performance.
These data indicate that W-DDGS can substitute for CM as the major protein source in dairy cow diets without negatively affecting ruminal fermentation, microbial protein production, and omasal nutrient flow, and can potentially increase dry matter intake and milk yield.
A study was conducted to determine the effects of including either wheat-based (W-DDGS) or corn-wheat blend (B-DDGS) dried distillers grains with solubles as the major protein source in low- or high-crude protein (CP) diets fed to dairy cows on ruminal function, microbial protein synthesis, omasal nutrient flows, urea-N recycling, and milk production.
Animals in group 1 were fed conventional concentrate mixture containing de-oiled groundnut cake (DGNC) as a major protein source, whereas, in groups 2 and 3, DGNC was replaced at 50% level with expeller pressed karanj cake and solvent extracted karanj cake, respectively.
In summary, our results indicate that both W-DDGS and B-DDGS can be included as the major protein sources in dairy cow diets without compromising nutrient supply and production performance.
In this study, we formulated five diets, namely, P1, P2, P3, P4 and P5, with Chlorella sp. powder, Spirulina platensis powder, yeast powder, soybean meal and corn gluten, respectively, as major protein sources.
Fishmeal and soybean meal were used as major protein sources.
Fishmeal, soybean meal, corn gluten meal and squid liver powder served as the major protein sources in the experimental diets; fish oil was used as the lipid source while dextrin flour was the carbohydrate source.
Wild game and fish are major protein sources, and smaller animals such as rats, wild chickens, and insects are also sometimes eaten.
