The heat production (HP) of broilers has been shown to increase through the years associated with higher breast meat yield, supporting the use of an energy system that better accounts for HP differences caused by changes in genetics, body composition (BC), nutrition, and environmental temperature. This study aimed to determine the influence of BC on fasting HP (FHP) and the sensitivity of models based on metabolic body weight (MBW) alone or including BC to determine the maintenance net...

Introduction: Smallholder pig farmers in east Africa report that lack of feed, seasonal feed shortages, quality and cost of feed are key constraints to pig rearing. Commercially prepared pig diets are too expensive and there is competition for food between pigs and people. Smallholder farmers typically feed nutritionally unbalanced diets. This results in low average daily gain (ADG) and poor farmer profits. The objective was to compare the ADG of Ugandan pigs fed forage-...

Introduction The Canadian beef industry produces over 1.5 million tonnes of high-quality protein annually while maintaining the highest standards in animal care and environmental sustainability (CCA, 2020). In Canada, access to in-feed antibiotics has been limited to veterinary prescription and growth claims have been removed. To keep up the high standards of efficient production and prudent antimicrobial stewardship in the beef industry, alternative feed additives like yeast...

I. INTRODUCTION A number of factors including the global population growth, shift towards high protein diets, finite land availability for crop production, climate uncertainties, increase in fossil fuel prices and diversion of feed ingredients, especially of cereals, to biofuel manufacture presents challenges to the global feed supply. This is a major threat for sustainable poultry production, in both the developing nations, as they move towards animal protein food regimen due...

Introduction: Betaine has been known as a functional nutrient widely used in animal nutrition during the last decade. It’s the trimethyl derivative of glycine, and is present in many plants and animal tissues such as aquatic invertebrates and sugar beets. As a feed additive, betaine is commonly used as anhydrous, monohydrate, and betaine hydrochloride. According to the latest research, the nutritional properties of betaine HCL is equal to anhydrous while offering...

INTRODUCTION Feed (ration) formulation is a technique by which different feed ingredients are combined to provide required nutrient to animals for a period of time, usually 24 hours, at different stages of production. A ration should supply all essential nutrients and energy to maintain vital physiological functions of growth, reproduction and health of animals. Ration should be palatable, digestible with permissible level of anti-nutritional...

I. INTRODUCTION Both glucose and amino acids are essential for muscle protein deposition and feed conversion efficiency and total tract nitrogen retention was reported to be influenced by protein and starch digestion in broiler chickens (Liu et al., 2013). Liu and Selle (2015) found that 76% of the variation in the feed-conversion ratio (FCR) could be attributed to starch and protein digestion rates in sorghum-based diets. Quadratic relationships between proximal jejunal...

Every year the marketing age of broilers decreases by an average of 0.75 days for the same performance. This trend is likely to continue in the same direction for the coming years. Nutrition plays a vital role in enabling this improvement. As the feed cost represents an expensive input (~70-80% of broiler production cost), the poultry producer should be aware of the dynamics of the feed in its influence on final product quantity and quality. Formulating feed ideally requires in-depth...

Consumers are basing their purchasing decisions on how the meat, milk, and eggs are raised. With more consumers and animal advocacy organizations pushing to reduce – or eliminate in some cases – the use of antibiotics in livestock production, several challenges have come to light. Many veterinarians and producers are...

1 INTRODUCTION During the last decades, the productivity of laying hens has improved significantly, with higher number of eggs produced over the laying cycle and higher efficiency to utilize feed nutrients. This increase in productivity implies in a change in the requirements, and consequently, these hens become more demanding in nutrients, mainly amino acids (Elliot, 2008). Optimization of protein supply by understanding the amino acid needs of these hens requires a thorough...

Introduction The gradual increase in the world's poultry production concomitantly increases the need for ingredients to supply protein for diets. Cereals constitute about 60 - 70% of diets to meet the energy requirements of poultry, whereas oilseeds contribute to cover the dietary protein requirements of birds (Senkoylu & Dale, 1999). Soybean meal (SBM) is the main protein source in poultry rations given its high nutritional value. Most of the European and Asian...

INTRODUCTION The acute hepatopancreatic necrosis disease (AHPND) has affected shrimp farming in several countries, like, Vietnam, Malaysia, Thailand, Mexico and in Philipines.1-6 The unique symptoms and characteristics of this disease consisting of massive sloughing of hepatopancreas epithelial cells. The external symptoms in infected shrimp like, empty stomach, bluish body color and shrunken hepatopancreas could be observed. The rate of mortaly is significantly higher...

The demand for alternative feed ingredients for animal diets keeps increasing. However, alternative feed ingredients could contain anti-nutritional factors. Arabinoxylan, high in wheat, forms the major constituents of the cell wall and encapsulates highly valuable nutrients in the wheat grain. Due to its viscous nature and high molecular weight, it hampers efficient nutrient absorption and digestion. Xylanase could be used to degrade the xylan bond and in turn, improve digestibility. The...

Introduction Much information is given ( Willem Van Cotthem, 2012 ) on Opuntia ficus-indica as an aloes. In Arabic is called Sabr, Teen Shoky, Teen Barbary, Hendy, Hendia, or Barshomy. It could be used commercially and industrially in treatment of some diseases (eyes, face, bone, prostate, colon, stomach, and intestine) and in cosmetic manufactures. It is a permanent plant grows in arid zones and tolerates drought and salt for its leaves that are filled...

Despite extensive research presenting both the benefits and detriments of soluble non-starch polysaccharides (sNSP) in poultry diets, its concentration and composition in feed ingredients is not commonly considered during commercial feed formulation. Consequently, a study was conducted in which birds were fed commercial-type diets formulated to Cobb recommendations (barley, corn, sorghum or wheat-based) formulated to contain similar protein levels but differing soluble NSP levels (Low,...
