Results of a 2005 inter-laboratory ring test on RF blue lake microtracer

Two years after the first ring test (i’Tec_H17) that followed the establishment of the new method for extracting and analysing RF-blue lake microtracer (i’Tec_H18), several animal feed research labs implemented this technique. Following on from the first study, and in agreement with Tecaliman’s supervisory board, a new ring test was set up to assess analysis […]
Method for measuring bulk density, tap density and the Hausner ratio for additives and feedstuffs

Following the purchase of a new powder compac-tion apparatus, Tecaliman decided to modify its measurement procedure for bulk and tap densi-ties, and the resulting Hausner ratio. The objective was to arrive at a procedure similar to the measu-ring technique used by Carr (1965), as applied to the Hosokawa apparatus. Abdullah and Geldart (1999) demonstrated that […]
Measuring the angle of repose (flow) found in animal feed additives

Tecaliman carried out the first angle of repose measurement tests based on a technique described in standard NF T 73-008 (1978) that we refer to as the angle of repose (distribution). The results obtained using this method initially designed for powder and pellet surface agents demonstrated that the method was not suitable for use with […]
Technical rules for assessing the level of carry-over between feedstuff batches

Industrial obligations allied with French and European regulations are driving feedstuff manufacturers to assess the level of carry-over on their production lines. These technical rules, which are recognised by several certification reference systems, can also be applied to manufacturers of mineral and additive premixes. These carry-overs consist of technically unavoidable traces of residual product in […]
Recommendation on a method designed to assess the health status of delivery trucks

In the late 1990s, a committee of industrials and quality experts developed a trial method for checking controls on the critical recontamination point as represented by delivery trucks during the transportation of heat-treated products (HTP). At a time both when the level of prevention relating to biosafety in the animal nutrition sector clearly needs to […]
Establishing decontamination scales via the pelleting of pig, laying hen, broiler and turkey feeds

European regulations 183/2005 of 12/01/05 and 2160/2003 of 17/11/03 are driving the animal feed sector to strengthen its control over the risk of salmonella infection. This legislation was incorporated into French law under the order of 23 April 2007, which focuses specifically on the treatment of feedstuffs destined for breeding laying hens. The requirements laid […]
Technical rules for assessing the bacteriolytic effectiveness of a pelleting line or a heat treatment

The implementation of European regulations 183/2005 of 12/01/05 that establishes feed hygiene requirements, and 2160/2003 of 17/11/03 on control of salmonella in the food chain led to the publication in the French Official Journal of the Order of 23 April 2007 relating to approvals of business operators in the animal feed sector. This order introduced […]
Proposed method for monitoring the cleanliness of an industrial animal feed site

This proposed method was developed in 1998, during meetings of a commission comprising industrial operators (Tecaliman, 1999). On the request of members of this commission, it is worth remembering that this method only serves as an example and that everyone is free to apply it or modify it in line with the risks occurring on […]
Survey on coolers installed in livestock feed plants in France – Ventilation

This technical sheet follows sheet no.88 and presents part of the results obtained during the survey on coolers, carried out in 2012. The section detailed below concerns more specifically the ventilation.
Grinding and pelleting behaviour of diverse maize batches

Prediction tables, based on the behaviour of raw materials in the pelleting press, are used to assess how the latter affect pellet quality, press yield and abrasiveness (MacMahon and Payne, 1983).
