The challenges and the potential of acidification in monogastric fish
 
In monogastric animals, including a wide variety of different fish species (ranging for instance from Salmon and trout via tilapia and seabass to Pangasius), the chemical breakdown is next to others achieved in the stomach through acidification. However, in some species or at certain stages during the lifetime, the acid production of a fish is limited. What kind of implications does this have for monogastric aquaculture species, which are heavily depending on the high protein inputs – and on the proper digestion of these expensive ingredients?

Effects of dietary potassium diformate on juvenile tilapia – a performance analysis

09/20/12

by Christian Lückstädt, Animal Nutritionist, ADDCON, Germany

Global production of farmed tilapia in at least 85 countries exceeded 3 million t in 2009 and requires high-quality fish feeds. In such intensive aquaculture production, bacterial diseases have been identified as a major cause of economic loss to producers. Feeding antibiotic-medicated feeds is a common practice to treat bacterial infections. Prophylactic use of antibiotics as growth promoters in aquaculture production has also occurred widely.

However, growing awareness from consumers and producers of aquaculture species has resulted in a demand for responsible and sustainable aquaculture. Regulatory authorities in most exporting countries now focus on the misuse of antibiotic growth promoters (AGP) in aquaculture, while public attention has shifted towards sustainable production methods....

New growth promoting products for the aquaculture industry

Dobble-salt technology on potassium diformate (KDF) triggers high interest at the shrimp farmers day in Thailand.

The Thai shrimp farmers day was held in Surat Thani, south Thailand, from February 12 to 13, 2011 and it was here that ADDCON presented its double-salt-technology based growth promoting products for the aquaculture industry in a newly designed booth. The company proudly presented latest results of research, in which the white shrimp (Litopenaneus vannamei) grew significantly better on receiving the growth promotor (KDF) included in the feed.

"The use of dietary acidifiers in salmonid nutrition" – by Christian Lückstädt

Routine use of antibiotics as growth promoters is a matter of debate in the animal farming industry. The use of low levels of these antibiotics in animal feeds possesses the possibility to transfer bacterial immunity to species pathogenic in animals and humans (Liem, 2004). The EU has banned all antibiotic growth promoters (AGP) from livestock production with effect of January 2006. Public opinion and regulation authorities in most of the export countries focusing now on the misuse of antibiotics in aquaculture and public attention have shifted towards production methods.

Utilization of Acidifiers in tilapia nutrition and feeding

A short review on the use of potassium-diformate

Routine use of antibiotics as growth promoters is a matter of debate in the animal farming industry. The use of low levels of these antibiotics in animal feeds potentially can transfer bacterial immunity to species pathogenic in animals and humans (Liem 2004). The EU has banned all antibiotic growth promoters (AGP) from livestock production with effect January 2006. Public opinion and regulating authorities in most export countries are focusing now on the misuse of antibiotics in aquaculture and public attention has shifted towards production methods. Therefore, alternatives to AGP are being sought worldwide in a variety of forms. Acidifiers consisting of organic acids and their salts present a promising alternative and they have received much attention as a potential replacement to improve the performance and the health of treated animals. In animal nutrition, acidifiers exert their effects on performance via three different ways (Freitag 2007): (a) in the feed; (b) in the gastro-intestinal tract of the animal; and (c) due to effects on the animal’s metabolism.
