Feeding trials

The effect of en2ymes, recorded in many feed trials, includes increased final weight of the animal, better feed utili2ation, improved feed conversion ratio (ECR), more homogeneous production, reduced mortaUty, and a reduced amount of sticky droppings (in chickens) (87). 

By this time, the product had proved, in continuing toxicity and feeding trials, to be safe and effective feed material.The process was patented and the trade name Pruteen given to the product A licence to sell the product as feed was granted by the Ministry of Agriculture, Fisheries and Food. 

Sc 5) Measure affinity for substrate/Measure protein content 6) Perform feeding trials in animals. 

Feeding trials would only be performed on selected organisms, perhaps on just one organism that appears suitable for production. There is no point performing such expensive trials until the characteristics of the organism in culture and chemical profiles (i.e. the operations in 3), 4) and 5)) have been carried out...

In 90-d feeding trials, the NOEL in rats is 5 mg/kg daily (Worthing and Hance, 1991). 

In 2-yr feeding trials, rats and dogs receiving 2,000 and 1,000 mg/kg, respectively, suffered no ill effects (WoPhing and Hance, 1991). 

The effective pretreatments for enzymatic hydrolysis of cellulose in hardwoods and agricultural residues have been developed over the past 90 years and new or improved ones are still being developed. The initial impetus for pretreatment research was the expansion of a feed base for ruminants (i.e., cattle and sheep). The concentration of pretreatment research on animal feed preparation placed an additional burden on researchers, because the product must be not only fully convertible to animal live-weight, but also nontoxic and palatable. Early feeding trials of pretreated fine sawdust to cattle produced very dismal results (55). This may be the reason, besides the...
