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
Forage Field will include a soil surgery, advice on plate metering, guidance on use of software to make the most from pasture, weed control, how to grow homegrown protein feeds
and best advice when it comes to baling and wrapping silage.
Effects of heat treatment on rumen CP degradability that were observed in this study are consistent with findings of several studies where oilseed protein feeds
have been evaluated.
The Feedstock Machine converts poultry and swine manure into high protein feeds
, natural oils, and high quality soil amendments.
"The devaluation of Russian rouble coupled with the five percent duty will make imported soybean meal less competitive in price than domestic feeds - and protein feeds
supply by the end of 2009 may shrink."
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.
Currently, 28-32% protein feeds
are available for grow-out of catfish (Robinson et al., 1994; Cho and Lovell, 2002; Li et al., 2003; Robinson et al., 2006).
