Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.

Gastrointestinal diseases pose a serious threat to industrial poultry breeding. Infections are caused by proliferation of naturally occurring intestinal microorganisms and their subsequent translocation to other organs and tissues of the birds. The consequences are a deterioration of feed conversion ratio, an increase in mortality and fnally a reduc- tion in productivity. According to the World Health Organization (WHO) this leads to a markedly increased risk of...

Abstract : The effect of dietary supplementation with Spirulina platensis algae-meal on the reproduction traits was studied in a one-year old pheasant flock. Three groups of penned pheasants with ≈100 hens plus 14 cocks per group were fed a basal diet supplemented with 0 %, 0.1% or 0.2 % algae-meal during the entire laying cycle of 12 weeks. The 0.2% algal group has laid by ≈14% more eggs per hen with a laying intensity higher by 8 %, compared to the...

Dear Sirs,
Dietary energy is a vital nutrient in livestock feeds. Since the grains market went up owing to its demand for bio-fuel the alternate feeds were searched. Sugar syrup was developed by me recently. The demand for it went up three times the production potential of the company and therefore, the company stopped its efforts for further development. My recent trials proved its potential to reduce cholesterol in milk, meat and egg I could not persue it further because of no support from...

Paper from the Australian Poultry Science Symposium Summary The combined inclusion of xylanase plus phytase in a wheat-based diet increased the ileal digestibility coefficients of 17 amino acids by an average of 8.6% (0.830 versus 0.764), which exceeded the average increases individually generated by xylanase (4.8%) or phytase (5.5%). Of probable relevance is that the combination of xylanase plus phytase markedly increased ileal...

Summary Maximising bird growth rate, feed efficiency and profitability of broiler production depends, among other factors, on accurate measurements of the apparent metabolisable energy (AME) content (MJ/kg) and AME intake (MJ/d) of cereal grain based diets. Near infrared (NIR) calibrations have been developed to measure these characteristics for cereal grains. Further research is being conducted to strengthen the...

A recent Poultry CRC study has shown that broilers raised on fibrous litter are generally more uniform in feed consumption, Feed Conversion Ratio (FCR) and, most importantly, body weight. This potentially greater uniformity holds the promise of less out of specification birds at the processing plant.
Moreen Ali, Laboratory Manager at Inghams, undertook comparative studies of the productivity and health of broilers raised on rice hulls, softwood sawdust, pine shavings, re-used single...

Improved broiler performance with the aid of organic acids has been reported from many sources. An important limitation, however, is that organic acids are rapidly metabolised from the fore-gut (crop to gizzard) of birds, which will reduce their impact on growth performance. ADDCON's patented poultry product FORMI NDF based on their unique double-salt technology has been proven to be effective in the whole gastro-intestinal tract (presentation at Poultry Nutrition Symposium in...

Phosphorus is an essential dietary nutrient for growing birds and is also essential for egg production and eggshell quality of laying hens. Even though an adequate amount of phosphorus is needed to support growth and production, there is a great concern about the contamination of land and water sources due to the phosphorus content in poultry manure. Thus, there is a great need to reduce the amount of phosphorus excreted in poultry manure by lowering the dietary...

The nutritive value of broiler diets containing rapeseed meals could be improved by appropriate xylanase-based enzymes, Chinese research has found.
In an in vitro and a broiler feeding trial Chinese researchers investigated the effect of fibre-degrading enzymes on the nutritive value of broiler diets containing hulled or dehulled Chinese double-low rapeseed meals.
Enzymes used were xylanase + β-glucanase (A), xylanase (B) and xylanase + cellulase (C)....

The development of resistance to certain antibiotics poses real problems to the animal and public health (Barton 2000, Hofacre et al., 2001). Consequently, many additives (prebiotics, probiotics, symbiotics...) raise a particular interest as products of substitution to antibiotics in order to improve the production performances and the health of animals (Bach 2001, Revington 2002). Pediococcus acidilactici is a probiotic bacterium that presents positive effects on the balance...

The Food Standards Agency has failed to support a ban on a poultry feed additive which contains the antimicrobial drug, nicarbazin. Nicarbazin residues have been a persistent problem in a high proportion of UK-produced chicken liver and in some chicken meat, but can also be found in more than a quarter of a million eggs eaten each day by British consumers. An EU scientific review [1] found that a safe level for residues could not be established...

Latest in enzyme technology boosts amino acid digestibility of broiler diets containing up to 18% DDGS.
Broiler producers looking for lower feed costs with distillers dried grains with solubles (DDGS) can use the latest developments in enzyme technology reported Dr David Ledoux at the 2009 International Poultry Scientific Forum, Atlanta, USA, 26-27 January 2009.
The use of DDGS in animal feed has increased with the growth of the bioethanol industry. Whilst DDGS is potentially...

Meat meal is an animal feedstuff produced by recycling animal by-products. These by-products include meat trimmings, inedible parts and organs, fetuses, and certain condemned carcasses. They are cooked (rendered) to produce a nutritional and economical feed ingredient. Blood, hair, hoofs, horns, manure, stomach contents, and hide trimmings are not permitted to be added to the meal. When bones are added to the meat meal it becomes meat and bone meal. Millions of tons of...

Importance of Early Feed Intake Feed intake is the single most important factor in determining growth rate of commercial broilers and turkeys. The data in Table 1 were obtained from industry sources and show that birds consuming feed the fastest weighed the most at processing and converted feed best. These data show what experienced growers have known for some time — flocks that do the best tend to be active and consume starter feeds quickly. It is also important to...

The unprecedented increase in feed prices during the past year are by now an unfortunate matter of record. The cost of virtually all feed ingredients, especially corn, soybean meal, phosphate, fat and even vitamins has gone far beyond any reasonable expectation. A number of causes for the current crisis have been cited, and their respective magnitudes debated, but it is certain that the massive diversion of feed ingredients to biofuels, reduced crop yields, and an increased demand for animal...
