Optimising nutrient density in a volatile market

The profitability of broiler production, expressed in its simplest form, is the value of the end product minus the input costs to produce that product. Of the input costs, feed is the major component. The ultimate challenge is to reduce input cost to a minimum, without compromising biological performance and profitability. A modelling approach can help to better calculate optimum diets.
By Dick Ziggers Breeding companies use very sophisticated programs to select the best bird for future performance. It takes four years before the current pedigree birds produce the... read more »

Rapeseed meal in animal diets

In the past few years, rapeseed cultivation has increased dramatically in the European Union, especially in countries like Germany, where renewable sources of energy are becoming important to national interests. Rapeseed oil has been proved to be one of the best sources for biodiesel, and an increasing amount of rapeseed meal has raised the level of interest among nutritionists and producers alike. In general, rapeseed is considered a good replacement, if only partially, for soybean meal in most animal diets. read more >

Application of soy protein concentrate in poultry pre-starter feed

Newly hatched birds have an under-developed digestive system and require highly digestible protein ingredients. Among commonly used plant protein sources, soy protein concentrate is an excellent plant protein ingredient for poultry pre-starter feed. read more >

Role of micronutrients in poultry production

Micronutrients are essential nutrients that birds require in small quantities to perform various vital physiological functions in the body. Even though dietary requirements are minor, they play a major role in the body metabolism, enzyme system, various physiological functions, reproduction and growth. However, most of these micronutrients cannot be synthesised by the bird itself. read more >

Vacuum core coating for pelleted feed

Fats and oils are increasingly important ingredients for energy in feed for pigs and poultry. But how to get these products into the pellet without detrimental effects to pellet quality? Vacuum core coating is one of the solutions. read more >

Astaxanthin: not only a pigment, but a health enhancer too

Astaxanthin is a naturally occurring carotenoid that pigments salmon, trout and other forms of seafood. Astaxanthin is routinely added in aquaculture diets to enhance natural pigmentation. Because of its unique bioactive properties, new promising uses also include enhancement of health, reproduction, and overall performance in fish, poultry and livestock. While synthetic astaxanthin dominates this market, the unique properties and consumer appeal of natural sources of astaxanthin like Haematococcus algae fuel their growing utilisation. read more >
