Spray-dried plasma improves feed conversion
Published: June 17, 2014
Summary
Spray-dried blood plasma is a highly digestible protein source containing immunoglobulins, growth factors, biologically active peptides, enzymes and other factors that are biologically active in the gut. Bovine SDP has been shown to produce improved growth rate, feed intake, feed efficiency and produce superior breast yield in broilers. Porcine SDP has been used in piglet starter diets to improve...

Blood meal feeding to broilers were recommended long back in the literature in a balance nutrition programs at some places where the blood meal manufacturing is cost effective. animal proteins are widely used and leading product could be MBM due to multiple benefits with bacterial threats are limited due to better storing infrastructures created. We need to know the nutritional chemical status of plasma meal and methods of plasma meal manufactured commercially . It may be better to have broiler ration basic ration with corn-soya base rather than wheat -soya base in my opinion. It is very good indication that we can use the wastage of slaughter house for broiler production but there is always a processing and preservation cost involved in animal products proteins than veg protein nutritional formulations in tropical climates hot and humidity situation. I thank to the team for such plannings for broiler nutrition as alternative protein source. Is there any species specific plasma meal nutrition is planned for broiler chickens?
thank you sir for good article. dr rathm

The true utility of plasma in broiler is not nutritional, so in this case the nutritional composition of plasma is not matter. The true advantage of plasma is that it improve the the sanitary status of intestine and therefore the nutrients of the diet (energy) are used mainly for functions of growth, more than for defense against of subclinical infections. This is the reason because the FCR improve when plasma is included in started diets not only in broilers

Keeping quality of animal protein is low. Already MBM are being used at 5% level in most feed in poultry. Some, though small, use fish meal also. Now using plasma meal will increase total animal protein share in feed. This has many benefits but increased susceptibility to infection majorly clostridium or NE in intestine. So you have to guard against these with utmost importance. Otherwise all the benefits will be geopardised.
However I believe these are necessary evils or compulsion.

just to say that doses of plasma in this experiment was just 0,5% (5 gr / kg) and dont seem correct to compare spray dried blood plasma with other animal protein ingredients like MBM or fish meal, these meals are just a source of nutritional proteins and their manufacturing process is very different from spray dried plasma. Plasma is a very safe product and a source of functional proteins with specific functions in the animal.

Can anybody tell me about the cost in dollar term?

Thanks for all the comments. Dr Santander is right, SDPP would be safer than most other animal products in view of its preparation. There have been issues with pigs, now being linked to a viral infection in piglets. This is likely because some SDPP is of porcine origin. I think this will be of benefit to the poultry industry - if the pig industry does not use SDPP, then the price will drastically reduce. Currently, it sells for about $A8000 per tonne in Australia. We have done several other experiments, to be published soon. We found that it could be fed at 0.05 % rather than 1 % and can be fed for 5 rather than 10 days, to achieve the same benefits. The cost of feed per unit BWG is also lower with SDPP than without it.

Prof Paul
Any thoughts why the first 10 d no effect but we saw an effect after 10 d even after withdrawal of SDPP

Hell Antrison,
The first 7-10 days represent a period of rapid development of the gastrointestinal tract. We have assessed this as part of our studies on SDPP. The product positively affects this development, which then tends to have an effect on subsequent growth and FCR. It is therefore worthwhile including SDPP in starter or pre-starter diets, a period during which feed consumption is also low. I do not think it will be economical feeding it throughout the production cycle, and in any case, does not seem to be necessary.
I would add that our studies were on a small scale and in cages. One study that was conduced on litter (also small-scale) did not show such extensive improvement in response. I think it will be worthwhile testing different dietary formulations and also a larger study on litter.

How can the birds get this spray?
It is difficult to apply
Is it economic approach?

Hi El-Sheikh, I have seen some interesting trials with soluble plasma in poultry, the application was in drinking water (like medicines), however the application of plasma powder in poultry feed could to have some losses of product (feed remaining after feeding). I think you have to consider a additional economic cost for these possible losses of plasma powder into the feed.

I wonder how do you explain the significant differences in FCR among five treatments at day 10 when weight gain as well as feed intake showed no treatment effects. Please show the CV's and test for treatment variance homogeneity.

poultry production has become a highly developed business all over world and there is no world wide board to accept the ingredients for poultry production or cattle production. In my opinion when we are approaching a stage where the safe food is widely promoted with certification for world wide trade reasons , i feel one board consisting technical persons need to say which are the products we can feed to animal when human food production is involved.My opinion veg feed for all animal would be appropriate when animal products are getting more attraction from bacterial growth as compered to corn soya diet feed ingredients.
It might be doing good in cold environment but not suitable in hot and humid climate and use of antibiotics as protective line would get in to disadvantage due to safe food criteria. However small markets can make any decision at their levels but we have to know that converting protein and fat from ingredient need good acceptable base of ingredients with acceptable aroma and sustainability to moisture contents of the ingredients. Thank you for a wonderful discussion on spray plasma protein for immunity of chick? dr rathm

Dear Prof El-Sheikh,
I just popped into this conversation. Spray Dried Animal Plasma is produced in different sites across Europe, but also in other areas of the World. The pure bovine source would possibly the ideal one, and Paul Iji's research shows performance with this ingredient. Profitability, we have seen in European settings, can reach around 4:1 , consistently via improved feed conversion, and seeing a trend in improved daily gain, but it will all depend on the stress factors in the specific production settings. If you want, we can share further information.
Best regards,
Victor

In commercial layers, we'd be targeting 2% inclusion in the first diet, and in the critical phases (18th week on wards? to 22?) and 0,5% during lay. It is a reference value, as environmental pressure /climate/ density feeding factors / raw materials used would challenge these doses up- or downwards.
