Abstract This study investigated the effects of bacterial inoculants and enzyme-based silage cocktails on dynamics fermentation, microbiome, nutritional value silages produced from low-quality biomasses reed, rice, corn straw. A 90-day ensiling trial was performed using five distinct combinations six basal species ( Lactobacillus plantarum , buchneri Pediococcus pentosaceus Aspergillus niger Bacillus subtilis Candida utilis ) three enzymes (xylanase, β-mannanase, glucanase). Each type...

• Eighteen patients were evaluated for primary symptoms of cervical dysphagia and/or laryngeal aspiration and subsequently had a cricopharyngeal myotomy. Twelve neurologic lesion as the cause symptoms. Four Zenker's diverticulum demonstrated by barium contrast roentgenograms. Two complained persistent suprasternal following one or more antireflux repairs gastroesophageal reflux disease. Esophageal manometry identified pharyngoesophageal motor disorder in all but four patients, two with who...

Protein is the main limiting factor and second most expensive feed component of poultry ration after energy. In many developing countries, prices are consistently increasing because dependency on imported soybean meal. order to decrease sector meal it necessary find sustainable alternative protein sources. This review summarises recent findings nutritive value maggot meal, earth worm worms silkworm discusses their potential as an source for sector.

Selenium (Se) is an essential nutrient with multiple health benefits to humans and animals. Cattle generally require dietary Se supplementation meet their daily requirements. The two main forms of in cattle are organic inorganic Se. Data comparing the productivity effects on still insufficient, it necessary conduct more research evaluate bioavailability, nutritional value, deposition, body functions sources different breeds physiological stages raised areas levels. objectives this study were...

This study evaluated the effect of heating methods on alteration protein molecular structure in flaxseed (Linum usitatissimum L.) relation to changes subfraction profile and digestion dairy cows. Seeds from two varieties, sampled replicate plots at locations, were evaluated. The seeds either maintained their raw state or heated an air-draft oven (dry heating) autoclave (moist for 60 min 120 °C by microwave irradiation (MIR) 5 min. Compared seeds, moist decreased (P < 0.05) soluble (SP)...

The growing food-feed-fuel competition, declining availability of traditional feeds, higher prices, and the urgent need to provide long-term sustainability for animal production have all triggered global research into optimum extraction energy nutrients from lignin-rich plant biomass. Recent studies shown that Pleurotus species white rot fungus can selectively degrade lignin in biomass; however, its effectiveness degrading depends on type substrate fungus. This study was therefore designed...
