Background Spray-dried plasma (SDP) is one of additives in swine diets [1–3] and contains high protein with balanced contents of amino acids and various physiological components, such as immunoglobulins, peptides, glycoproteins, and others [4], that contribute to modulation of microbial populations [5, 6], immune responses and inflammation [4, 7, 8], and intestinal morphology [8, 9], and others [4]. Based on these beneficial effects, SDP is typically used in nursery...

1. Introduction The use of tannin in ruminant nutrition is increasing, mainly due to its diverse positive effects in several aspects concerning physiology, metabolism, and animal performance. However, research results are quite controversial regarding the concentrations and sources used, which reinforces the need for further studies to elucidate these still evident gaps. According to Haslam and Lilley [1], tannins represent secondary compounds of plants and are present in...

1. Introduction
The appearance of new transmittable plant diseases is determined by anthropogenic and conservational change, including changes in trade, land use, and climate [1–4]. The growth of infected plant material through trade in plant products, germplasm, grafts, and live plants has been recognised as the greatest contributing factor to the emergence of new plant diseases [5–7]. A pathogen may be introduced without disease emergence initially...

I. INTRODUCTION Dietary electrolyte balance (DEB) is defined by the interrelationship between sodium (Na + ), potassium (K + ) and chloride (Cl - ) where DEB = Na ++ K + -Cl - as mEq/kg and it plays an influential role in homeostasis of the body fluids. Borges et al. (2004) investigated DEB in two experiments and concluded that there was a quadratic effect on weight gain and feed conversion efficiency (FCE) when the DEB was...

Improving poultry meat quality along with cutting down the cost of production has been one of the major objectives of most farmers and nutritionists. To achieve this objective, several strategies have been adopted, one of which is dietary energy management. Energy is the foremost important and largest part of poultry feed. This energy is either comes from grains like corn, wheat, soy, etc or through fat. ...

Introduction Supplemental lipids are commonly included in diets for ruminants (Doreau and Ferlay 1994). These lipids are components of feedstuffs or through the addition of specific lipid additives (Loften et al. 2014). Most commonly, these lipid additives are used to increase the energy density of the diet (Hess et al. 2008), but can also be used to modulate the fatty acid (FA) composition of body tissues or induce metabolic changes. Verdugo (2016)...

The demand for fish protein hydrolysate products across the animal feed and pet food applications will attain traction on account of the increasing requirement for new functional foods. There is a significant influx of advanced throughput technologies that exhibit low environmental impact and superior economic sustainability.
Fish protein hydrolysates have excellent nutritive value as well as amino content and are consumed as either stand-alone items or components of functional...

1. Introduction Phytogenic feed additives (PFA) are the plant derived products used to improve performance of livestock and poultry (Windisch et al., 2008; Jacela et al., 2010). The PFA comprise of a wide variety of herbs, spices and products derived thereof and are mainly essential oils. This class of feed additives is at present used to a great extent as alternatives to the antibiotic growth promoters (AGP) in poultry and swine nutrition. Obviously, the ban imposed on the...

INTRODUCTION Disease control, high production, product quality, and reasonable production costs have been the recent main goals of the poultry industry. Hence, meeting per capita consumption and welfare to humans necessitates continuous efficient and goal-oriented healthcare to control disease spread and decrease the application of antibiotics (1). These endeavors will include the launch of programs to control infectious diseases, face the constant changes in political and...

INTRODUCTION Sorghum ( Sorghum bicolor (L.) Moench) is a tropical forage species widely used in ruminant nutrition. Sorghum is considered the best option in arid and semi-arid regions worldwide. Sorghum is a typical plant of hot climates due to its xerophilic characteristics, low soil fertility requirements, high tolerance/resistance to water stress and salinity (HASSAN et al., 2018). Sorghum grain has been used as an energy source in ruminant diet formulation and...

INTRODUCTION Preservation of alfalfa as silage is becoming convenient due to the ease of mechanization and reduced susceptibility to weather damage (Khadem et al . 2009). Calberry et al . (2003); Bhandari et al. (2008) and Khadem et al. (2009) reported that cows fed on ration containing chopped alfalfa hay had lower intake than those fed on a diet containing chopped alfalfa silage. But similar milk yield and composition (Calberry et al ....

1. Introduction In Nigeria today, despite the significant investment in commercial agriculture by the government, aid agencies, multilateral organizations and individuals, livestock production has not succeeded in meeting the protein demands in the country (Oluwatayo and Adedeji, 2019) [1]. The increasing human population in the country has indicated that the conventional forms of livestock production and artisanal fisheries which have been over-exploited will not be sufficient...

Introduction The poultry industry in Nigeria is an essential subsector of agriculture that provides food, employment, and other economic resources for the country (Ezekiel et al. 2012a). Livestock production can be threatened when feeds are contaminated by fungi and their toxic metabolites. Several mycotoxins, including aflatoxins (AFs), cyclopiazonic acid (CPA ), fumonisins (FUMs ), nivalenol (N IV ) and zearalenone (ZEN) have been reported to contaminate poultry feed and their...

1. Introduction Mycotoxins are harmful secondary metabolites produced by fungi that contaminate a wide range of food and feed products [1–3]. Depending on the frequency of occurrence and/or the severity of the disease that they produce, mycotoxins belonging to the aflatoxin, ochratoxin, and Fusarium toxin groups exert great impacts on animal/human health as well as on global trade [2,4]. Aflatoxin B1 (AFB1), zearalenone (ZEA), ochratoxin A (OTA), and deoxynivalenol (DON)...
