Feed formulation
Welcome to the page about Feed formulation of Engormix; a source of knowledge on Feed formulation.
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,...

Due to the high cost of feed for poultry, there is continuous pressure to formulate ‘least-cost’ diets that meet nutritional requirements. However, the main aim of any commercial enterprise is usually to maximise profits with the resources or inputs available. The increasingly dynamic nature of egg supply and volatility of egg price in Australia has reinforced the need for a more sophisticated approach than the total reliance on least-cost ration formulation alone for the...

Back in 2013, in the very first blog I published on the Insta-Pro website, I wrote about how extrusion processing, especially high-shear dry extrusion from Insta-Pro, was a reliable way to produce better ingredients and make it easier for animals to extract more dietary energy for productive purposes. Animals need energy to make meat, milk,...

Trace minerals are indispensable components in poultry diets. Minerals like Calcium, Phosphorus, and Manganese play a major role in growth, bone development of birds, whereas Copper and Zinc are responsible for maintaining the feather color. Minerals have a key role in enzyme structure like Catalase (Fe), carbonic anhydrous (Zn), SOD (Cu, Zn, Mn) and GSH (Se). There are two forms of trace elements available to birds ie., Inorganic and Organic form. Trace minerals in inorganic forms such as...

Introduction Soybean meal (SBM) is the most important and preferred source of quality protein in animal feeds (Banaszkiewicz, 2011). Among the oil seeds, SBM contains the highest crude protein (CP) and has the best AA profile, with only 6% crude fibre (Dei, 2011). The AAs in SBM are highly digestible by poultry (Newkirk, 2010). Based on the CP content, SBM can generally be classified as high protein (47% - 50%), or low protein (44% - 46%). Popescu & Criste (2003) suggested...
