“…The impact of feed on growth and feed conversion will mainly depend on the used ingredients and on their quality (Tacon, 1994). Also, processing of food plays an important role in food quality, safety, storage and characteristics of specific food item (Chen et al, 1999). Feeding represent over 50% of the operational costs of aquaculture (Jauncey & Ross, 1982;Tacon, 1993 andEl-sayed, 1999).…”

The present study deals with the effect of four commercially prepared diets on the length-weight relationship, condition factors, growth performance and feed utilization of the cichlid fish, Oreochromis niloticus fingerling reared in glass aquaria. The major components of diets included proteins, fats and carbohydrates of each feed type. The diets were analyzed for verification of values written on its commercial label. Data showed that, the standard length of the fish fed on the different diets did not vary significantly where it ranges between 6.28 ± 0.9 cm in diet II to 6.66 ± 0.8 cm in diet I. The same pattern of change was also noticed in comparing the weight of fishes fed on the four diets. Data indicated that, fish feeding on diet IV demonstrate the lowest weight being on the average of 8.86 ± 1.97 gm, while, fish feeding on diet I showed the highest weight being averaged 10.37 ± 3.2 gm. The growth of fish is nearly isometric in the first three diets and negative allometric in the fourth one. The values of condition factors are slightly differences among different diets. The highest value (3.46) of coefficient of condition (k) was recorded in the fish fed on diet II and the lowest value (3.09) in the fish fed on diet III. The highest average value (1.07) of the relative condition factor (kn) and the lowest (0.90) were recorded in the fish fed on diet III. The lowest value of total weight gain, average daily gain and specific growth rate were detected in the fish fed on diet IV. The value of feed intake of diet I is better than the values obtained from the other feed diets. The best feed conversion ratio (1.87) was recorded in the fish fed on diet II. The lower protein efficiency ratio (0.25) was recorded with diet IV and the higher protein efficiency ratio (0.53) was recorded with diet II.

“…Brzoska et al (1998) indicated a direct correlation between the levels of dietary 0)3 (n-3) fatty acids and reduced incidence of hypertension, atherosclerosis, and/or cardiovascular diseases. Ruminant products of appropriate fatty acid composition might be a source of health-promoting substances, which are beneficial in prevention and treatment of various diseases ranging from headache to heart problems, cancer and oxidative stress (Chen et al, 1999). From this point of view, the fatty acid composition of fat in the diet or reaching the duodenum might be more important than the amount of fat as an energy source in the diet.…”

The effect of energy source in diets on duodenal flow of bacteria N and fatty acids was measured in an experiment on four sheep in a 4x4 Latin square design. The basal diet for control animals consisting of 40% concentrate and 60% meadow hay was supplemented for experimental animals with 6% of rape seed oil, saccharose, or starch as an additional energy source. The energy supplement did not change rumen pH (P>0.05), but decreased (P<0.05) rumen ammonia-N from 41.6 mmol in the control group to 15.6,17.5 and 23.3 mmol in groups receiving rape seed oil, saccharose, or starch, respectively. A similar declining tendency was found for total volatile fatty acids and the majority of individual ones. Duodenal flow of bacteria N calculated from 2,6-diaminopimelic acid content was not significantly affected by the diet. The ratio of 2,6-diaminopimelic acid to total nitrogen content in digesta was lower in control than experimental groups, indicating a higher proportion of bacterial protein in the digesta of animals receiving additional energy in diets. The proportion of unsaturated as well as saturated fatty acids in the digesta of animals fed diets supplemented with starch was lower (PO.05) than in the remaining groups. The duodenal digesta of animals fed the diet supplemented with rape seed oil contained significantly higher (PO.05) polyunsaturated n-3, monounsaturated and saturated fatty acid proportions compared with the remaining groups. These results demonstrate that feeding sheep with diets supplemented with energy decreases ammonia and volatile fatty acid levels in the rumen fluid whereas only addition of rape seed oil increases the proportions of polyunsaturated n-3, monounsaturated and saturated fatty acid in the fat of duodenal digesta.
