Animal Fat in Broiler Ration

It has been observed that there are lots of controversies in poultry nutrition regarding the use of feed ingredients from Animal sources. Many poultry experts are against to use animal sources such as Meat cum bone meal and Animal fat in poultry feed. 

But nowadays, due to use of highly modern Rendering technologies, the By-products of Abattoirs such as MBM and Animal Fat produced are of best nutritional quality. Those products are sterilized and having a good self life. Due to those properties now its need of poultry industry to use those products in poultry feed as a good Protein and energy sources.

Now all poultry feed manufactures are using Meat cum bone meal in poultry feed as a conventional item but some controversies till there to use of Animal fat in it. So till date lots of feed manufactures are considering animal fat as a Non- conventional Item in poultry feed. In concern to this, we have conducted the field trials to know the Impact of use of animal fat in poultry feed.

Materials and Methods

We have selected the farms randomly from the list of Broiler Contract farmers under Sahakar Agrovet, Ahamadnagar (Maharashtra). This firm was facing problems of Ascites too in the summer season also so they have decided to reduce the energy in Finisher feed. As per that after decreasing energy value by 100 Kcal he was successful to control the mortality of Ascites but at the same time FCR has been damaged and production cost was also increased. Then I have advised him to use 50% crude Soya oil and 50% Animal fat without decreasing the energy in feed. As per that he had make changes in the feed formulations.

Ingredients used in Broiler finisher Diet

Maize, Soya Doc, MBM, Soya crude oil, Animal Fat and maize gluten were the Major Ingredients used in feed formulation.

Nutritional Values (Broiler Finisher Diet)

Crude Protein% - 19.5, Metabolic energy - 3280 Kcal/kg, C: P ratio: 170

In both the groups the Nutritional values maintained were same as above and ingredients used were also same except Animal fat.

When they have started to use the Animal Fat in their feed formulations, their feed cost was decreased by 30 paisa per kg.

The Economics for the same was as:

The Rate of Soya crude oil was at Rs.46/kg Free on road while rate of Animal fat was at Rs.31/kg free on road 

Cost of Soya Crude oil used in feed formulations @4%:

4 x 46 = 184 per 100 kg feed so for 1 kg feed = Rs.1.84

Cost of Soya Crude oil used @ 2% + Animal Fat used @ 2% in feed Formulation:

2 x 46 + 2 x 31 = 92 + 62 = 154 per 100 kg feed so for 1 kg feed = Rs. 1.54

So they have saved Rs.0.30 per kg finisher feed after replacing 4% Soya crude Oil by 2% Animal Fat and 2% Soya crude oil in feed formulations

Summary & Discussions

This Study has been solved the below frequently asked questions (FAQ's) by Farmers:

1) Gross Energy obtained from Animal fat was very low i.e. around 8200 Kcal/kg?

This study has proven that by using the Animal Fat in feed by replacing 50 % quantity of soya crude Oil in Finisher diet will get the synergistic effect on gross energy values i.e. by using 50% Soya crude oil + 50% Animal fat will give us 9000 kcal/kg gross energy.

2) By using animal sources in poultry feed chances of bacterial infections are more?

If you look after results shown in table you can understood that mortality % was low on the feed having Animal fat in there formulations as compare to the other group. Apart from that they were succeed to overcome the problem of Ascites and heat stroke mortality.

3) Difficult to use/Handle?

Many feed manufacturers have to put the animal fat melting and spraying machinery at their feed mills which are low cost also. This Company/firm has installed such machinery from Pune based Company and running well without any trouble.

This field study has been proved that poultry birds will give better performance on the feed having balance of Saturated and unsaturated fatty acids in their formulations.

5) Storage life?

Unsaturated fatty acids are more prone to Oxidative rancidity over Saturated fat. So as Soya crude oil contains more unsaturated fatty acids that will be become more rancid than Animal fat if come in contact with air.



Note

Since output of above results, this customer is using this blend of Oils (Soya Crude Oil + Animal Fat) consistently and getting better results. Highlighting his recent results summary month wise.
