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 in...
Dear Dorji
Another good book :Nutrition and Feeding of Poultry (From Larbier and LeClercq). You can start with this one . Is a little bit more simple , After this you can take the " commercial poultry production " from Summer. Both are excellent.
Because we are in a right direction and we all agree about the non using of antibiotics in poultry feeding I want to ask you about your biosecurity protocols may you have , about how you make washing of the houses , the disinfection , what kind of vaccinations you use etc
Hi every body?. Thanks to Dr. Gunasekar for all información we received
A question:
1. Could you do some comment about alifatic amino acid Leucina, isoleucina and valina? Their interrelationship?
2. What about for the free fatty acid content in an oil? Which was the upper limit. It was decrease the metabolizable energy?
Indonesian Institute of Sciences (LIPI) at Jogjakarta, Indonesia also improved the alternative material for replace the antibiotic in feed poultry, we extract the Lumbricus rubellus, herbal (Morinda citrifolia) and also use LAB (lactic acid bacteria) for this purpose.. Someday, we believe Indonesia will also banned the uses of AGP in feed poultry..
Verry good question mr Briceno. Valine is considered the 4th limiting amino acid for broilers feed on diets containing ingredients from vegetable origin.The linoleic levels are very interested . But , I consider is better to start a new topic for that . Because this are not regularly questions and I am verry interested for the answers .
Dear, Lonut.
I have done research on comparative study on antibiotic and organic acids as growth promoters. During my experiment I found that, organic acids had better response on broiler performance. I observed 0% mortality in organic acid group and 6.44% in antibiotic group. O.A reduce the Salmonella and Colliform counts from the sample. Thus, in feed we can use O.A as growth promoting agent instead of antibiotics. Best FCR was also noted in O.A supplemented group as compare with antibiotic.
I agree with the previous comments. Feed quality, handling and animal management will lead to good broiler performance. Antibiotics use can be minimized with some dietary manipulations
Totally agree with you Zakria. I always use OA for water sanitisation. Usualy I use OA for decrese the water ph to 4.25-4.45 (against salmonella). Ofcourse , OA have a lot of benefits but I use this special for this rol . Against salmonella. But , on the other hand , I know a lot of farms who did not use and have same results like us. And for your test- 6.44 with antibiotic? why? what was the reason of this dead ? overdosing of antibiotic?
Dear Mr Dr Haralanov-what is mean MEAT?
Thank you Mr. Zakria for sharing your research findings. i have agreed with your results but how is the meat quality and its there any residual effect found. i would like to suggest Mr. Zakria to share more result of your trail iterms like FCR.. growth as per the target weight. i have concern more on it because i have to purchase some organic acid to improve my feed quality.
what was type of organic acid you used ??
what types of organic acid should be used for broiler feed.
is directive for using of organic acid rather than antibiotic.....
thank you for your kind information ......
Dear sir.
The best formulation do not mean anything.
We have a lot of best formulation - best formulation for fast growing , best formulation for price of feed , best formulation for the cost of the meat .... we have a lot of best formulation.
What do you want? best price of feed (compared with something) , best speed of growing of chicks (like broiler specification guide) or best price of meat ?
And first question - what kind of broilers do you have?
After all please take attention to this: for best result you must have all perfect: house, feed and poultry. All this are working together.
All the best.
Since broilers are fast growing birds nutritionists aims at formulating rations that promotes this purpose by using ingredients that are rich in protein . This can be very expensive anyway. But the use of natural growth promoters now helps to reduce feed cost in this regard. Bio-ingredients limited in Nigeria sells and markets a probiotic called GRO UP. This is popular with some nutritionists here and some broiler farms.
As growing competition in feed industry especially in broiler feed. what level of crude protein for Prestarter (0-10), Starter(11-20) and grower (21-35) Rations for 1.5 FCR as mind going towards 22.5%, 21.5% and 20% Respectively. if we offer two feeds starter (0-15) and grower (16-35) as mind goes towards crude protein levels 22.5% and 21.5% with proper energy levels and amino acid balance for controlled environment. It really sound me a kind of HD feed to compete in industry.
Bird performance in the commercial poultry industry has shown a staggering improvement over recent decades. Modern broilers weigh about 2.5 kg at 39 days, with a live-weight feed conversion ratio of 1.6 kg of feed per kilogram of body weight gain. There are many ways to assess the quality of proteins, but nevertheless they are all related to amino acid supply, which thus becomes a key feature in animal nutrition. For many years, poultry feed formulation was based on the concept of crude protein, which often resulted in higher amino acid levels than those required by the birds. Broiler responses of economic interest, such as BW gain, FCR, and breast meat yield (BMY), can be optimized by increasing amino acid (AA) concentrations, improving the AA balance, or both.
Birds are not able to properly utilize this excess of amino acids, which is reduced to nitrogen and excreted as uric acid. Excessive protein levels in the feed do not only mean high formulation costs, but can also affect poultry performance. As the number of economically available synthetic amino acids increase, the crude protein level will be increasingly reduced. . According to Pack (1995), amino acid requirements must indubitably be expressed on digestible base, instead of total base.
The availability of different nutritional recommendations is a problem in establishing the best nutrition for broilers, as it generates doubts as to which recommendation should be used. The interactions among dietary amino acids must be considered. There will be a response to lysine only if methionine is adequately supplied, showing the importance of providing a well-balanced amino acid profile.
