INTRODUCTION Free radicals are responsible for aging and causative agents of various human diseases. Antioxidant compounds play an important role in various fields such as medical field (to treat cancers, cardiovascular disorders, and chronic inflammations), cosmetics (anti-aging process) and food industries (food preservative) [1]. Seaweeds contain reactive antioxidant molecules, such as ascorbate and glutathione (GSH) when fresh, as well as secondary metabolites including...

1. Introduction Maize is the most common energy source used in commercial monogastric diets, especially in the American, Southern Europe and most Asian countries where maize grain is the primary cereal for poultry feeds (Dei, 2017). However, the nutritional value of maize for livestock feeding can vary (Cowieson, 2005). Genotype, agronomic conditions and pre- and post-harvest processing can affect the chemical characteristics of cereal grains (Gehring et al., 2013). Indeed...

Fermentation products with main and side activities Feed enzymes are mostly produced by fungi or bacteria. Those living organisms produce a wide variety of different enzyme proteins. For commercial practice, only a limited number of those activities is assayed in the laboratory. Assaying e.g. the xylanase activity obviously results in a quantification of the xylanase level, while not providing information about other activities that remain present in the fermentation product. In...

From Dr Ildar Nisamedtinov’s presentation at Lallemand’s International Selenium Yeast seminar (Grenaa, Denmark, 2007) Alkosel®R397 is made from a natural yeast strain, Saccharomyces cerevisiae NCYC R397, selected for its ability to incorporate large amounts of selenium into amino acids (selenomethionine in particular, selenocsyteine). To insure optimal selenium incorporation, S.c. R397 is grown in the presence of measured amounts of inorganic selenium, during a tightly controlled...

1. INTRODUCTION Several studies have linked declining reproduction especially male fertility to toxicants found in the environment, particularly endocrine-disrupting chemicals (EDCs), such as phthalates (Wong and Cheng, 2011; Nordkap et al., 2012). One of the phthalates, Di-n-butyl phthalate (DBP) has attracted special attention due to high production volume in millions of tons annually (Swan and Elkin, 1999; Guerra et al., 2010). As a result, human and...

Yellow grease is the result of recycling used oil from fast food restaurants and then waste animal fat from slaughterhouses for poultry, swine and cattle is added. Theoretically, yellow grease is filtered and stabilized with antioxidant, then stored for export. Some exporters have the nutritional profile. In fact, yellow grease may be contaminated with toxic waste such as water contaminated with bacteria, residual oil used in motor vehicles (as...

1. Introduction Biochar (BC) is obtained via the pyrolysis of organic material. In the process, biomass is treated by heat in very low oxygen (or other oxidizers) content, where complex chemical compounds are transformed into simpler ones, eventually yielding gaseous products such as water vapor, carbon dioxide (CO 2 ), carbon monoxide (CO), hydrogen (H 2 ), methane (CH 4 ), ethane (C 2 H 6 ), and also solid carbon residue often named...

INTRODUCTION Aquaculture is the fastest growing source of animal protein for humans. However, as this industry continues to develop, several inherent challenges will arise. Foremost is the need for increased production of suitable and sustainable feeds. Aquaculture has long been criticized for ‘‘using fish protein to make fish protein’’ ( Naylor et al., 2009 ). This ‘‘fishmeal trap’’ ( New & Wijkström, 2002 )...

INTRODUCTION The continuous growth of aquaculture production based on fishmeal (FM) is fundamentally unsustainable, since most wild fisheries stocks are already beyond their catch limits (FAO, 2018). Plant-based ingredients, such as soy protein concentrate (SPC), are sustainable products widely used by the aquaculture industry as an important source of protein (ABDUL KADER et al., 2012). Fermented SPC is an innovative product, based on aerobic SPC fermentation using the bacteria...

INTRODUCTION Like other animal production systems, aquaculture has developed into a highly globalized trade-dependent industry, therefore as global fish farming continues to increase, the need for formulating nutritionally balanced and cost-effective diets with high-quality protein source is important (Furuya et al., 2010). In fact, nutritional value of protein in the diet for fish is influenced by its amino acids(AA) compositions, therefore, the quality...

Introduction The use of enzyme complex in animal feeding improves the utilization of nutrients that would otherwise be unavailable (Leite et al., 2011), reflecting positively on the performance and reducing the pollution load of excreta (Opalinski et al., 2010). However, the inclusion of enzymes in formulations should be made carefully, because this additive may lose their biological activity during pelleting process, which involves high temperatures, moisture, and...

Prevalence of numerous livestock diseases and increasing emphasis on animal health is expected to augment yeast market share for the animal feed application. The demand for high-quality meat has propelled significantly across the globe in recent years. In a bid to follow a high-protein diet, consumers are steadily shifting towards animal-based products.
Use of yeast in animal feed could help meet this growing demand. The product can stimulate growth of infant and young aged...

How best can Saponin, Trypsin, Phobol ester, Phytate, Phenol, Lectin and Tannin be eliminated to the nearest minimum tolerance level in our seeds. A lot of resources are wasting away in Africa especially seeds, leaves and roots that can be used as an alternative feed ingredients in poultry feed are not put into use because of anti nutritional factors especially those listed above that constitute major problems. We Animal nutritionists are working tirelessly both private and government...

Nutrition plays a major role in the performance of layer birds. Feed management is the most important practice to get egg production at a right time, maximum peak production, long standing peak production, standard egg size, good cull bird weight and reduced feed cost per egg. Body weight should be taken every week from 1 st week to 18 th week of age, the birds with less body weight...

The global feed phytogenics market, an intrinsic sub-vertical of the food, nutrition, and animal feed industry, has been observing massive growth over the recent years, subject to mounting prevalence of livestock diseases and deteriorating animal health. In fact, reports suggest that livestock producers lose up to USD 21 billion to animal diseases every year. This count also disrupts the living of nearly 1 billion people who rely massively on livestock products like eggs, dairy, and meat....

Introduction. Organic selenium (OSe) has an advantage in reducing oxidative stress in comparison to inorganic forms and incorporates into skeletal muscles, kidney, liver, and gastrointestinal mucosa proteins as selenomethionine and selenocysteine. It is an essential micronutrient for fish (Martinez-Alvarez et al., 2005). Yeast cell wall has been proven as an immunostimulant and health improver for fish and other animals (Selim & Reda, 2015). Materials...
