you can ask same question relating to human being. Why you have to provide protein diet to children. It is a growing stage and protein is directly related for growth.
So the answer could be for growth in calves.
No. It is probably one of the most unwise management feeding decisions you can make for your calves. It is not advisable nor recommended to feed weaner calves feed that is meant for an animal that has a completely different digestive system--and thus different nutritional requirements--than they. One big difference is fat content in feed: Young calves, like these weaned calves, should not have more than 4 percent fat in their diet. A horse's diet can have at least 8 percent fat in it, which may affect these calves in a way you wouldn't want to have happen to you. For instance, you may find the feed intake (which affects average daily gain) will decrease if they are fed a ration and cause scouring or diarrhea. The protein content of this horse feed may be lower than what these calves need: Weaned calves, or calves weighing around 500 to 800 lbs, need 14 percent crude protein in their diet. Feed for mature horses and mules only has 8 to 10 percent protein, which is not enough for these calves. How much carbohydrate is in the feed will affect your horses negatively but will be what these calves may need. These calves will need around 60 percent TDN in their diet in order to grow. Since you would only supply no more than 0.3 to 0.4 percent of a mature horse's body weight in cereal grains per feeding, that is not nearly enough for these calves, but it may be too much if the feed is too high in fat. The ratio of calcium to phosphorus for cattle is different than for horses. For your steeds, optimum Ca:P ratio is between 1:1 to 3:1, though it's fine to go up to 6:1. Ideally, for horses, the Ca:P ratio should be 2:1. For cattle, must be fed feed that is between the ratios of 2:1 to 7:1 Ca:P. Also, the K/(Mg+Ca):P ratio (or tetany ratio) for cattle cannot exceed 2.2:1. For horses, such a ratio is unimportant and often ignored because such issues as tetany does not pose a significant risk in equines. With all this in mind, it is highly recommend you feed your horse and mule feed to your horses and mules, and purchase feed specially formulated and made for your weaner calves.
Your pigeons are likely not receiving enough protein in their diet. Look for a better brand of feed with more protein.
You can get more protein in your diet by eating lean meats, red meats, protein powder, fish, and things like that. There are even protein pills you can take.
A cat that is fed a diet of fish will more than likely not experience any more health problems than other cats. Fish is protein and cats can handle a lot of protein without it harming them. A varied diet is always better for anything than feeding one type of food.
No south beach is not the only high protein diet. There is also the Atkins diet. They basically are built on the same principles to eliminate carbs and eat more protein.
There are many sites decidicated to this diet, but this ones seems to have the most information. http://www.webmd.com/diet/protein-power-what-it-is
High-protein diets take a page from the low-carb craze. The goal is to lose weight by eating more protein-packed foods, which often means consuming fewer carbohydrates. The portion of total calories derived from protein is what defines a high-protein diet. In a typical diet 10%-15% of daily calories come from protein. In a high-protein diet, this number can be as high as 30%-50%.
A protein diet is one which concentrates on protein rather than carbohydrates and fats. High protein diets are often used for weight loss as they tend to burn more fat. A good diet should include all the food groups.
To increase your protein intake in a vegetarian diet, try to consume foods like beans, lentils, nuts, and dairy. Also, you can supplement with protein powders.
A high protein diet can have a lot of great benefits on your fitness and health level. The added protein in your diet will help to promote faster repair and development of your muscles after a workout. Not only will a protein diet help you develop larger muscles, but a high protein diet is also known to enhance your daily energy level. These benefits are a huge part of why so many people are taking in more protein.
The protien diet is a low-carb and high protein diet. More information is available at the following: www.webmd.com/...crohns.../crohns.../creating-a-crohns-disease-die...
Because they're losing protein from the milk they produce.
