Recent trials confirm that the introduc-tion of a versatile NSP (Non-Starch Polysaccharides) enzyme in pig diets,

improves performance and homogenei-ty of animals from weaning to slaughter. This has a positive impact on health management by a reduction of re-allotting and increased clean downtime.

The homogeneity within batches is not always measured and/or reported in trial reports although it is worth looking at. Pig producers know that in respect of a minimal clean downtime between batches and a limited mixing across batches, it is necessary to ensure proper animal health management. Low performance and/or high heterogeneity between animals make it difficult.

In practice, it means that more homo-geneous animals spend less time in the facilities because the time between the first and the last individual to reach target weight is reduced. More homogeneous animals also means less mixing both after weaning and when animals are brought to fattening rooms, which reduces stress and the spread of pathogens. Enzymes can contribute to increase piglets and pig homogeneity; as proven by recent research achieved in col-laboration with Adisseo testing Rovabio® Excel, added on top of the usual formulation.

Besides the general effect of an efficient NSP enzyme to increase digestibility, a ver-satile enzyme containing a wide range of enzymatic activities, may have more assets than a mono-activity enzyme to impact each individual metabolism and counteract animal diversity.

From -16 to -26% on piglet final weight variability

In the experimental station of a customer in France, a trial was conducted on piglets fed a barley-based diet from 42 to 70 days of age. Daily weight gain was improved by 3.9%, and feed conversion rate was reduced by 4.3% with Rovabio® Excel (Table 1). Moreover, the coefficient of variation decreased by 16 percent, proving the effect

of the enzyme on homogeneity of the batch. The first wick-ers graph (Graph 1) clearly shows that final weight of the lightest piglets is sig-nificantly increased with Rovabio® (27.2 kg vs 23.7 kg).

This trial con-firms the results observed in two other trials carried out in Germany. The University Of Applied Sciences of Nürtingen, showed that the addition of Rovabio® Excel on a wheat-based diet improved piglet growth perform-ances (Table 2) with a final weight increase of +1 kg (+ 3.4%). The coefficient of vari-ation on final body weight was reduced by 20 percent and the gap between the lightest and the heaviest piglets was significantly reduced - from 20 kg to 13 kg with Rovabio® (Graph 2).

At the University of München, the piglets fed a corn-soybean diet showed that Rovabio® Excel sig-nificantly improved piglet performances (see Table 3). As a result, piglets receiv-ing Rovabio® were

heavier (+ 3.7 % at 70 days of age). Final weight variability was significantly reduced by 26 percent.

From the piglet weight distribution at the end of the three experimentations, the number of days needed to reach target weight could be determined. The first indica-tor to be considered is the number of days needed to bring the last piglet to target weight. However, to be closer to manage-ment practice on field, a second indicator was calculated: the number of days needed to bring 75 percent of the piglet batch to target weight, when usually the batch can leave the weaning facilities.

A positive impact kept until slaughter

A trial was carried out in 2012 from weaning to slaughter and confirmed that the reduction of variability with Rovabio® Excel is also demonstrated during the fattening period, and that the time needed to reach slaughter weight is more homogeneous with Rovabio® across individuals.

This trial conducted on corn-based diets at the Kasetsart University in Thailand, shows that Rovabio® Excel decreases feed conversion ratio by 4.5% and significantly reduces the variability within batch (-72%). The faster growth brings a potential reduction of the fatten-ing period by three days, and the reduc-

tion of heterogeneity allows reducing the fattening period by seven extra days for 75 percent of the batch to reach 100 kg bodyweight. Altogether, with the addi-tion of a versatile enzyme from weaning to slaughter, the fattening period can be reduced by ten days and the number of overweight or down-graded pigs can poten-t ia l ly be reduced.

In these four trials with differ-ent diets and metabolic phases, in all cases, growth performances and animal homogene-ity were significantly improved with Rovabio® Excel until slaughter. This has been possi-ble thanks to the versatility of Rovabio®. The fact that Rovabio® contains 19 enzymatic activities allows a posi-tive response over animal homogeneity

on diverse diet types and unique metabolic specificities.

To reduce insect infestation, a common practice is the use of fumigation. The chemi-cal products used have to expertly and care-fully managed, for safety reasons. And do not decrease grain temperature.

The Conserfrio® system The Conserfrio® system can be used

independently of ambient weather con-ditions. Even under rain or fog there’s no risk of rewetting the grain. Our system is based on the making of con-stant conditions under which the grain storage is easy, natural, safe and profit earning.

Practices like turning the grain to cool it have weak success and waste lots of energy, also breaking some percentage of grains.

There are many direct savings and ben-efits related to a correct chilled conservation. The most important are:• Avoiding fumigation means cost savings • Less weight loss, in other words higher

product output at the end of storage time

• Higher product quality means a higher selling price

• Higher head grains after the milling process. This point is especially important in the rice industry

• Energy savings in the drying process. It is possible and safe to store product with a higher moisture content if grain temperature is low. A drying-cooling combination achieves relevant energy savings.

All of these benefits give a very quick payback of the capital investment in the chillers, typically achieved in one or two years.

Our system is suitable to be used in silos (made of metal or concrete, flat bottom or conical bottom) and warehouses, not need-ing additional civil works. The cooling units need only electrical energy.

The chiller replaces the fan. The chilled, dry air is introduced into the silo through existing ducts.

In warehouses, the chilled air may be introduced through ducts placed under or over floor. In both cases a ducting system must be previously installed.

ConclusionThe system

has demon-strated to be the most natural and cost-effec-tive to preserve grains, seeds and perishable granulates dur-ing storage. A low storing tem-perature not only reduces the product vital metabolic activ-ity but also most of the troubles of a storing without control.

Typical users of chilled aera-tion are from small farms with as little as 100 ton storage up to large plants with storing capacities of around 100,000, 500,000 or even 1,000,000 mt.

Rice mills, flour mills, feed mills, malting plants, oilseed crushing plants

and grain storage facilities can all benefit of our technology.

Consergra is pioneer in the applica-tion of chilled aeration in many products. Throughout the years, we have gained lots of experience in the bulk preserva-tion of products such as paddy rice in all its varieties and lengths, cargo rice, milled rice, maize, wheat, barley, sunflower seeds, cotton seeds, beans, soybeans and green coffee beans to name but a few.

In benefit of the human and animal health and of the environment as well, grains and seeds must be responsibly treated as food.
