Two experiments were conducted to evaluate the effects of irradiated ingredients in meal and pelleted diets on nursery pig performance. In Exp. 1, a total of 192 pigs (initial BW, 6.0 kg) were used in a 25-d experiment. Pigs were blocked by BW and randomly allotted in a 2 x 2 factorial arrangement of treatments with main effects of diet form (meal or pellet) and either irradiated (11.92 kGy) or...

I . A total of six diets based on maize silage were formulated to examine the effect of proteinand non-protein-nitrogen, and energy supplementation on the flow of amino acids to the small intestine and the synthesis of microbial amino acids in the rumen of growing cattle. All diets contained 24 g total nitrogen (N)/kg dry matter (DM), of which 550 g N/kg total N was supplied by either urea or f...

this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Ž . The replacement of fish meal protein with soybean meal SB or protein concentrates made Ž . Ž . from narrow-leafed lupin LP or field peas PP was investigated in extruded feeds for Atlantic Ž . salmon. Salmon 47 g were fed for 63 days on extruded feeds containing each of the plant meals to replace 25% and 33% of the fish meal protein and performance compared against a nutritionally Ž . balanc...

A seventy-five-day feeding study was performed to investigate the usage of black soldier fly (Hermetia illucens) larvae meal as an alternative protein source in carp diets (Cyprinus carpio). In this study, experimental fish were fed with four different (fish meal-based without Black (BSFL) (BSFL0), 50% (BSFL50), 65% (BSFL65), and 75% (BSFL75) substitution BSFL), triplicate. The carps (1.045±0.0...

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...

Every year, the world’s reserves of aquatic biological resources are depleted, so breeding and cultivation fish, shrimp shellfish becomes a reliable way to provide population with enough fish seafood. Recently, aquaculture has faced serious problems, including limited species diversity, labor intensity technological processes, environmental pollution, diseases others. For its reproduction, late...

A comprehensive study of feed staff animal origin was carried out to identify the most efficient ways use as components compound feeds. In samples feeds (fish meal, fish extrudate, meat and bone meal), parameters nutritional value safety were determined. It found that stable content crude protein essential critical amino acids characteristic which is advisable be used for purpose balancing youn...

Reduction of feed costs is a major concern of poultry producers. However, replacement of components of a corn-soybean diet with a lower-cost alternative requires the assessment not only of poultry performance and carcass characteristics but also of resulting meat quality. A brief overview of research studies, conducted over the past 10 yr, investigating the effects of alternative poultry feedst...
