A study was undertaken to evaluate the nutritive value and digestibility of Azolla in ruminants by in vitro techniques. The crude protein, crude fibre and ether extract contents were at a level of 21.37%, 12.5% and 2.3%, respectively. The neutral and acid detergent fibre levels were about 35.4 and 23.9%, respectively. The average in vitro dry matter digestibility, in vitro organic matter digest...

in this study, fish meal (fm) was replaced by the black soldier fly maggot meal (bsfm) with replacement levels at 0%, 25%, 50%, 75% and 100%. the feeding trial was conducted for 56 days and the effect of each replacement level on the growth performance, feed utilization, body composition and survival of the experimental fish was assessed. all the experimental diets were well accepted by the fis...

pearl millet has tolerance to harsh growing conditions such as drought. it is at least equivalent to maize and generally superior to sorghum in protein content and metabolizable energy levels. thus it is of importance for poultry feeding. amino acid (aa) determination is expensive and time consuming. therefore nutritionists have prompted a search for alternatives to estimate aa levels. traditio...

Hazelnut (Corylus avellna L.) is one of the important nut crops in world. The harvesting ofhazelnuts is done either by hand or by manual or mechanical raking of fallen nuts in Iran.Common hazel is widely cultivated for its nuts, including in commercial orchards in Europe,Turkey, and Iran. There are some genotypes of hazelnut in Iran that their growing areas arelimited to Gillan, Aredbil, Mazand...

Black soldier fly (BSF) larvae, Hermetia illucens L., develops on organic wastes, reducing ecological pollution and converting waste biomass into protein and fat rich insect biomass. BSF can replace increasingly expensive protein sources used in poultry, aquaculture and livestock compound diet formulation, such as fish meal and soybean meal, which holds the potential to alleviate future food an...

The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (m...

Goal. To study the nutritional value and polyphenolic composition of annual sunflower leaves (Helianthus annuus L.) for their further use as a phytogenic antioxidant additive poultry feed. Methods. The chemical phytoraw material (crude protein, crude fat, fiber, calcium, phosphorus, vitamin E, b-carotene) was evaluated according to generally accepted met­hods. quantitative content individual gr...
