Bovine rumen fluid was fermented anaerobically over 48 h with cottonseed, corn, alfalfa, or a mixture of these substrates in anaerobic mineral buffer. Samples taken at different incubation times were derivatized with n-butanol and subjected to gas chromatography and mass spectroscopy. No unusual fermentation end-products from the cottonseed substrate were detected. Cottonseed supported rumen fe...

Globally, food-producing animals consume 70 to 90% of genetically engineered (GE) crop biomass. This review briefly summarizes the scientific literature on performance and health of animals consuming feed containing GE ingredients and composition of products derived from them. It also discusses the field experience of feeding GE feed sources to commercial livestock populations and summarizes th...

Corn is the main component in manufacture of feed which functions as an energy source for poultry and ruminants. Requirements quality corn a ingredient are regulated Indonesian National Standard (SNI) includes moisture content, damaged seeds, mouldy foreign matter aflatoxin. The purpose this reserch was to evaluated analyzed whether it accordance with SNI 2020. In research, secondary data used ...

Abstract Mycotoxins are secondary metabolites produced by various fungi and known to have a significant negative impact on human animal health. When feedstuffs contaminated with mycotoxins, their toxicities may be caused variety of diseases. In this study, the residual mycotoxins in were analyzed using LC–MS/MS incorporated QuEChERS extraction. Analytical method validation was performed for LOD...

As the aquaculture industry becomes increasingly conscious of costs and benefits, it is searching for more “functional” feeds, many of which are augmented with key ingredients and compounds that promote animal growth and survival. In addition, plant proteins are increasingly used as alternatives to proteins from animal sources. The optimum production of feedstuffs with optimum dry matter conver...

Ochratoxin A (OTA) contamination often causes large economic losses on livestock production. The intake of feed contaminated by OTA also represents a potential risk for animal health and a food safety issue due to the transfer of the toxin through the food chain to humans. The aim of this paper is to review the available literature on: (1) the frequency and degree of occurrence of OTA in differ...

Nutrition can help reduce the impact of pork production on the environment and improve pig gut health. The formulation of diets based on highly-digestible feedstuffs and which meet the exact requirements of the pigs, markedly reduces the excretion of minerals such as nitrogen and phosphorus into the environment. The presence of fermentable dietary fiber in the diet can also decrease the emissio...

Increased cost of common feedstuffs and increased availability of coproducts from plant-based biofuel manufacturing has enhanced interest in the use of these coproducts in rations for dairy cattle (Donkin and Doane, 2007). Glycerol (commonly marketed as crude glycerine with a glycerol content of approximately 80%) is a coproduct produced during biodiesel production from soybean oil and is becom...
