the effects of phytase and glycosidase supplementation to diets containing rice bran on broiler performance were investigated by using 200 day old (308 ross) broiler chicks in a completely randomized design with five treatments and four replicates. the five dietary treatments were as: corn-soybean meal based diet; diet containing rice bran; diet containing rice bran supplemented with natafous; ...

Phytate P utilization from soybean meal (SBM) included in broiler diets has been shown to be poor and highly dependent on dietary Ca intake. However, the effect of Ca on P utilization and on the optimal ratio of Ca to nonphytate P (Ca:NPP) when diets contained varying levels of phytate has not been clearly shown and was the objective of this research. A factorial treatment structure was used wi...

background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar tothe diet with 0.0 LnA/LA ratio but different in total amounts of C18polyunsaturated fatty ac...

In Sterile Insect Technique (SIT) programs, mass-reared males of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), are maintained on a sugar-agar diet before their release into the environment. Several studies suggest that nitrogenous dietary supplements improve the mating competitiveness of the sterile males, thus increasing the cost effectiveness of SIT. Other research, however, ha...

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, gro...

Ž . Coho salmon smolts Oncorhynchus kisutch were fed one of three casein-based diets Ž . Ž . containing different levels of vitamin E Vit. E and Selenium Se . Diet 1 contained no Ž y1 supplemental Vit. E or Se, diet 2 contained moderate levels Vit. Es30 IU kg and Ses0.2 y1. Ž y1 y1. mg kg and diet 3 contained high levels Vit. Es900 IU kg and Ses1.0 mg kg . Smolts Ž were reared for 6 weeks on th...

an experiment was conducted to determine the appropriate methionine level in broiler breeder’s diet. the treatments consisted of 6 levels of methionine (0.2, 0.25, 0.3, 0.35, 0.4 and 0.45% diets), with 4 replicates of 7 hens each for a duration of 8 weeks and for ages of 28 to 35 weeks. diets contained similar levels of protein metabolizable energy. the levels of the other amino acids were take...

 This study was carried out to investigate the apparent digestibility coefficients (ADCs) value of protein, amino acid and energy and body amino acid composition of rainbow trout fed solvent extracted soybean meal (SBM) and full-fat soybean meal (FFS) partly replacing fish meal (FM) in diets. Five iso nitrogenous (average 50.36% crude protein) and energetic (4294 kcal/kg total energy) diets wer...

The efficacy of a recombinantly derived microbial phytase (Natuphos 5000, BASF Corp.) was evaluated in sorghum-soybean meal-based diets of finishing swine. During the 50- to 80- and 80- to 118-kg BW intervals, diets contained .40 and .39% plant P, respectively; control diets fed during the two weight intervals were supplemented with .08 and .04% inorganic P from dicalcium phosphate. The all pla...
