Pro’s and cons on the use of different formulation techniques for feed additives

The factors that determine the quality of feed additives are the particle size [and its distribution], the targeted concentration of the active material in the final feed and the formulation technique use to manufacture the additive. This leads to the following conclusions.

Reducing particle size of feed additives gives a higher chance of a homogenous feed mix. However, too small particles are prone to percolation and loss through filters and sticking onto equipment.

Increasing particle size reduces the risk of feed mill contamination and carry-over. However, increasing particle size decreases the distributability of the active material with the risk that not all animals receive the correct (not too few and not too much) amount of active material with their daily diet.

Simple mixing is an unsuited technique for manufacturing of additives. Such products do not meet the quality requirements of the feed industry today. Other formulation technologies (fluid bed processing, mixer granulation and vacuum coating) exist which are better suited to obtain the desired characteristics of the feed additive.

A properly formulated and granulated feed additive [in terms of plasticity, hardness and disintegrating behaviour], with the correct size reduces risk in operation of a feed plant .It ensures that the proper amount of active material reaches the animal and is liberated ‘on-site’ in the digestive tract. It’s a means of reducing risk with feed additives and ensuring safety to both people and animals in the feed and food chain

Enzymes and fat addition

There are conflicting opinions regarding the application of enzymes at the fat coater. Should enzymes be applied to the feed before the fat, and then be exposed to the high fat temperature and risk of enzyme inactivation, or should they be applied post-fat application. With the concern then focusing on the enzyme’s ability to penetrate the fat coating on the pellets? Assay work carried out with samples from the commercial feed mills have shown there to be no clear interaction between enzyme stability and recovery, pre- or post-fat application, of the enzyme at the fat coater. Research cited by Engelen (1998) also supports this view. The recovery of Xylanase LC was shown to be unchanged irrespective of the fat temperature, the fat level and the spraying order.

Make your own Dairy feed through MakeFeed

MakeFeed Dairy is comprehensive feed formulation software, designed to combine the expertise, knowledge and standards of recent technologies in the field of Dairy nutrition. It is a simple, efficient and effective tool for formulation of rations for cattle and buffalo, which would be immensely helpful for dairy nutritionists, farmers, entrepreneurs, scientists, teachers and students alike. The present computer package MakeFeed Dairy has the sole objective to prepare the best feeds for cattle and dairy animals that would be optimum in all nutrients as well as minimum in cost. The software will be of immense benefit for both of small-scale farmers to feed industry manufacturers. The feeding cost alone being the major constraint in dairy enterprise, every effort has been directed to contain feed cost maintaining feed quality following optimum requirements of various nutrients including energy, protein, minerals etc for concentrate preparation. It would also help in preparation of whole ration with the best combination of other feed resources. In this package, safe/effective inclusion levels of different feed ingredients have been considered for the formulation of rations. MakeFeed Dairy is a Windows based unique software for efficient balanced formulation of concentrate and whole ration for different age groups cattle and buffalo for cost-effective maximum production performance. It provides information on nutritive values for a wide range of feed ingredients along with the maximum inclusion level for each ingredient. The users have options to edit the complete database of feed ingredients and modify suitably, add or delete particular feed ingredient due to change in nutritive composition and availability of feed ingredients.

The cost of the software package is Rupees 3000/- only, which includes the compact disc containing the software and a comprehensive user manual. Those who want to receive the software by post, please remit Rs. 100/- extra towards the processing, handling and postal charges. Please send your bank draft in favour of Director, Central Avian Research Institute, Izatnagar, Bareilly and payable to State bank of India, CARI Branch (Code 7027).

For purchase send a draft of software RS. 3100/- for dairy in favour of the Director, CARI, Izatnagar-243 122, UP payable at SBI, CARI branch (Code 7027).
