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.
Poultry production is a business, which like any other enterprise seeks to generate profit. This is done by keeping production costs as low as possible. Wilson & Bayer (2000) found that feed cost is about 60 -70% of the total cost of production, and energy alone contributes about 70% of the feed cost (Saleh et al. 2004). Poultry were observed to eat the amount of feed that approximately meets their energy requirements (Rose, 2001). In addition, they consume a daily amount of food that...

Dear Users,
This is an interesting forum from our Spanish community, generated by Gabriella Olivieri from Venezuela:
Hi, I want to ask a question about the supply of minerals in broilers:
I provided 200 grams of mineral (FOSVIT 20 of the CIA. Turtle Brazil) for every 40 kilos of concentrate, at 2 days after arriving the chicks, it has improved the yield in weight, but there is mortality at 16 days by infarction, and at 35 days this mortality is increased to 13.
I thank you any...

Summary During the last decades important triggers for innovation have been the reduction of the output of minerals and nitrogen to the environment and the ban by the EU on the preventive addition of antibiotic growth promoters (AGP’s) to feeds. A good protein evaluation system with an accurate estimation of requirements will minimise the output of nitrogen to the environment, improve intestinal health and performance. AGP’s have a direct effect on the numbers of...

Very little data is available on the fiber fractions of different feed ingredients e.g (arabinoxylnas, beta glucans, mannans, pectins, lignin, cellulose etc). What is the percentage of different fiber fractions in a particular ingredient and how much of these are degradable with particular enzyme addition? Before addition of enzyme in any ration substrate identification is compulsory. Enzyme addition in the form of single or cocktain preprations without knowing the exact proportions of fiber...

Paper from the Australian Poultry Science Symposium The degree of grain grinding may influence the efficacy of exogenous enzymes in poultry diets, but published data on this aspect are limited. Amerah et al. (2008) reported that the effectiveness of exogenous xylanase in broiler diets is influenced by the particle size (PS) of wheat. The aim of the present experiment was to examine the interaction between maize PS and...

Dear Users, This is an interesting forum from our Spanish community, generated by Joaquin A. Paulino from República Dominicana: Birds do not have a crude protein requirement, they only need an amount of nitrogen for the synthesis of essential amino acids. The ideal protein concept, investigated by Boorman (University of Nottingham) and Baker University of Illinois), is defined as the exact contribution of all amino acids with no excess or deficit for...

Introduction. The most vital nutrient in the poultry ration is considered 'dietary energy' even though energy itself is not converted into Glucose in meat or egg except for liponeogenesis. Moreover; it is used as fuel for the synthesis of meat or egg. Therefore 60-65 % of the metabolisible energy in the poultry ration is imputed to carbohydrate. Other nutrients are normally adjusted based on the feed intake of the bird. There exists a relationship between energy and digestible...

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...
