phytate in poultry rations containing rice bran (rb) critically reduce poultry performance while increasing n and p excretion. the objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. twenty days old male broiler chicks (n=180) in 60 floor pens wer...

Two hunared day old broiler chicks were alloted to five treatment groups evaluate the effect of whole soyabean and fish meal supplementation on productivity experimental birds. Feed consump­tion weight gains similar diets 1 -and 3, while feed efficiency protein ratio better (P<0.05) cooked diet 3 as compared groundnut cake based (control) ration. Fish also unproved performance. The raw gave ...

I. Using shccp fitted with re-entrant cannulas in the proximal duodenum, and which were given a ration containing long straw, a series of three experiments was conducted in which the flow of digcsta to the duodenum was measured and sampled continuously for 3 d. Therc appeared to be no consistent effect of this procedure on total flow of digesta to the duodenum from day to day, indicating that u...

An important issue of food supply for servicemen with individual needs is the adjustment diets through use protein, vitamin and mineral components which are functional ingredients such food, primarily flour based, products as: bread, bakery confectionery (cookies, crackers, gingerbread), fruit nut energy bars, “Granola” breakfast cereals. The priority task to increase nutritional biological val...

Methods of housing and managing the milk-fed dairy calf have changed considerably in recent years. We review key developments and how these affect calf welfare. Limit feeding of milk is recognized as both a welfare and production risk. Conventional limit feeding methods (i.e. approximately 10% BW/d) result in signs of chronic hunger, abnormal behavior, poor weight gains and poorer lifetime perf...

LMEYER, J. H. Interactions qf dietary jibe7 and protein on food intake and body composition of growing rats.Am.J. Physiol. 193(3) : 488-494. q@-The addition of cellulose to the diet increases protein needs as measured by gains in the fat-free body of ad libitum and pair-fed growing rats. This was attributed to loss of metabolic fecal nitrogen induced by dietary cellulose addition. It was demons...
