Feedstuffs

Welcome to the page about Feedstuffs of Engormix; a source of knowledge on Feedstuffs.
Introduction: Tropical native legumes are an alternative to cost-intensive conventional feedstuffs. However, the adverse climate in the tropics induces pest and diseases during storage, affecting the nutritional quality of the feedstuff. Ensiling can face this problem and moreover improve digestibility or reduce the content of anti-nutritional factors (ANF). This study inquired the effects of ensiling a mixture of soaked cowpea (CWP) and sorghum (SOR) grains on fermentation...

Rendering involves repurposing animal co-products that would otherwise be discarded. It converts the parts of a meat animal we choose not to eat into stable, usable materials such as fuel, pet food, and livestock feed, creating a highly sustainable alternative. Below, learn more about products made from rendered materials in detail. You can discover...

Dietary alfalfa may improve broiler growth, but fiber inclusion may be detrimental during coccidiosis challenge. Alfalfa is a source of health-promoting bioactive compounds (phytochemicals) that may offer several benefits to the poultry industry by direct action or by influencing the microbial communities in chickens. Iowa State University researchers recently examined the role late-cutting alfalfa — either as ground hay or a lipid-soluble extract — may have on...

Pressure on feed cost is and will remain a decisive factor for profitability and sustainability in pork and poultry production. In the backdrop of soaring inflation, other production costs have escalated. Corollary minimizing the costs associated with production has never been of greater importance. Arguably, feed formulation is a precise science that seek to compute combination of feedstuffs to meet the requirement of an animal at least/best cost. Traditionally, the two primary factors that...

Dairy goats can be highly productive to the level of exceeding that of dairy cattle on a metabolic body size basis. Far too often and due to limited controlled research studies, feeding practices used for dairy cattle are extrapolated to feeding dairy goats. Similarly, commercial supplements are formulated for sheep and goats even though there are well known nutritional differences, namely copper nutrition where goats have a higher requirement like cattle. Goats are selective browsers...

The formation of a viscous gut content in the small intestine due to the presence of non-starch polysaccharides in feed can markedly restrict efficient nutrient digestion in poultry. This adverse effect may be mediated through the supplementation of exogenous feed additives. The present study investigated the effects of carbohydrases and a buffered formic acid on growth performance and ileal digesta viscosity in broiler chickens fed a wheat- or maize diet. A 2 × 4 factorial arrangement...

Reduced protein (RP) diets have received increasing interest in poultry nutrition due to the potential benefits in feed cost and environmental footprint (Liu et al., 2021). Understanding the order of limiting amino acids (AA) in RP diets is critical to ensure requirements are met cost effectively. To date, only the first three limiting AA (including lysine [Lys], methionine [Met], and threonine [Thr]) have been demonstrated in RP layer diets, while the order of the next most limiting AA is...

Diego Martínez (University of Arkansas)       An energy system is needed to optimize feed formulation and influence economics and sustainability. This study assessed the sensitivity of productive energy (PE) and classic net energy (CNE) to BW gain (BWG), feed conversion ratio (FCR), and net energy for gain (NEg) and maintenance (NEm), and developed models to predict BWG, FCR, and protein accretion (PAC). 1920 chicks in 96 pens were assigned to one...

Nelson Ruiz (Nelson Ruiz Nutrition LLC)     A set of 24 solvent extracted commercial soybean meal (CSBM) samples, which corresponded to the same lots of CSBM used in the field, were evaluated. The CSBM were from different origins (Argentina, Bolivia, Paraguay, Trinidad & Tobago, U.S.). The objective herein was to evaluate the relationship between KOH protein solubility (KOHPS, a measurement of overprocessing) and trypsin inhibitor activity (TIA, a...

INTRODUCTION Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe [teleomorph: Gibberella zeae (Schwein.) Petch], is an economically important disease of barley (Hordeum vulgare L.) that has resulted in massive commercial losses (Wilson et al., 2018). F. graminearum is capable of producing multiple, type B trichothecene mycotoxins [Deoxynivalenol (DON), 3-acetyldeoxynivalenol (3ADON), 15-acetyldeoxynivalenol (15ADON), nivalenol (NIV), and 4-acetylnivalenol (4-ANIV)],...

INTRODUCTION Maize (Zea mays) is one of the main sources for food and feed production in the world (Chulze, 2010). In 2017, more than 197 million hectares were grown with maize worldwide resulting in production yield of 1.13 billion tons of maize (FAOSTAT, 2020). Ensuring the quality and safety of maize for feed and food production is essential. One of the major quality and safety concerns is infection of the maize plants with fungi and the contamination of maize kernels with...

Introduction A wide range of in vitro and in situ techniques are used as alternatives to in vivo measurement of ruminal fiber availability. Fiber digestibility and forage fragility are critical factors should to be considered in forage evaluation and diet formulation for ruminants. Digestive characters of dietary neutral detergent fibers (NDF) fraction have been reported to greatly affect feeding behavior, chewing activity, rate of particles...

I. INTRODUCTION Nutrient requirements are established by means of dose-response studies. Data is subjected to appropriate regression analysis and the level needed to maximise a given response (body weight gain, feed efficiency, carcass yield, etc.,) is defined as ‘requirement’. The estimates are compiled as ‘tables of nutrient requirement’ e.g., NRC, CVB, Brazilian Tables, nutrition guides by the genetic suppliers, and are used by field nutritionists as...

I. INTRODUCTION In the 1990s, researchers from the American Soybean Association (ASA) showed that soybean meal with similar proximate analysis can perform very differently in poultry and swine feeding. Subsequently, Creswell and Swick (2008) carried out feeding trials, AME and digestible amino acid analysis of 4 soybean meals. They found that there was a large difference between the soybean meals in BWG and FCR from the broiler feeding trials as well as in AME and digestible lysine....

I. INTRODUCTION Cereal grains such as wheat, sorghum, barley and maize are commonly used in poultry diets as the main source of energy. Knowledge on the metabolisable energy content of cereal grains is critical for their efficient use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME has been the globally accepted system for describing the dietary energy content for poultry. Modern, commercial broiler...
