Protein Feeds

Protein Feeds

 

feeds of plant and animal origin with a high protein content. Among the green feeds, the largest amount of high-quality protein is found in the young grass of legumes—from 132 grams (for clover) to 218 grams (for feed beans) of digestible protein per fodder unit. Of the grain feeds, legumes are also rich in protein; one fodder unit of pea grain contains up to 158 grams of digestible protein, beans have 211 grams, and soy beans have 223. There is a great deal of protein in the flour and bran of legumes, in wheat, millet, oil cake, groats, and baking and feed yeasts.

Feeds of animal origin are distinguished not only by richness but also by the high biological value of the protein. Meat meal contains 480 grams of digestible protein per fodder unit, the best varieties of fish meal have more than 600 grams, and dry blood has up to 554 grams.

The most common non-protein nitrogen (NPN) source used in ruminant feeding is urea, due to its low cost; thus, when prices of protein feeds escalate (i.e., soybean meal), it is economical to use urea as a nitrogen supplement in ruminant diets.
Factors that hamper the growth of fish meal market are availability of various alternate protein feeds including meat and soybean meal.
In Pakistan, information on protein degradability of protein feeds is scanty.

The experimental feeds were grouped into three types (fiber, protein, or lipid), and each type contained 5 feed component levels (low, medium low, base, medium high, and high) with levels (proportions) of the manipulated component ranging as follows: Fiber feeds = 2.3% to 11.3% fiber by dry weight; Protein feeds = 20.1% to 45% protein by dry weight; and Lipid Feeds = 3.5% to 13.5% lipid by dry weight.
The lower growth increase with diets containing 10% crude protein compared to the higher protein feeds suggested that this protein level was growth-limiting or that the growth-enhancing factor may be related to the protein fraction of the diet that was present at adequate levels to stimulate PL growth at 18% crude protein but not at 10%.
In the case of protein feeds, soybean oilcake and lupine produced the highest C[H.sub.4] levels (7.09-7.33 g/kg digested feed) followed by soybean meal and palm cake.
