Embodiment 1

[0080] Composition of "EXL" Yeast Extract

[0081] The EXL yeast extract used in Examples 2 and 3 is a yeast extract obtained by enzymatically hydrolyzing one yeast of Saccharomyces cerevisiae (species) and removing a water-insoluble portion. The yeast extract at 5% in hot water forms a slightly opalescent solution. It is a micronized powder that allows dust-free operation. The yeast extract contains about 10% by mass of peptides between 1000 and 10,000 Daltons.

[0082] The main properties of this yeast extract are shown in Table 1.

[0083] Yeast extracts of this type are readily available on the market and can be purchased inter alia from the company Bio Springer (94701 Maisons-Alfort, France), it being understood that the major manufacturers of yeast This type of yeast extract is available in the product line Hydrolyzate and Yeast Extract.

[0088] Effect of "EXL" Yeast Extract on Tail Phishing in Pigs

[0089] EXL yeast extract was added to the drinking water for three consecutive weeks in a pig finishing unit with known and recurring risk of tail phagocytosis. The treatment was based on a weekly dose of 75 mg / kg live weight administered in triplicate (25 mg / kg live weight / pig, repeated three times a week) during the first week, followed by a single dose of 25 mg / kg One weekly dose live weight / pig. This yeast extract was supplemented only after tail phagocytosis was reported. After three weeks, it can be seen that supplementation with EXL yeast extract more than doubled the occurrence (amount) of tail phagocytosis and this was statistically significant (p<0.05).

Embodiment 3

[0091] Effect of "EXL" yeast extract on peck-induced mortality in laying hens

[0092] The effect of EXL yeast extract on laying hen mortality was evaluated in a factory farm from 19 to 30 weeks.

[0093] 800 laying hens (Isa Brown species) reared in cages at a density of five chickens per cage were fed with a wheat-based feed, the composition of which is shown in Table 2.

[0094] The following experimental design was used:

[0095] - 400 laying hens without supplements (control)

[0096] - 400 laying hens, supplemented with EXL.

[0097] EXL yeast extract was added to the drinking water for a period of 12 weeks, based on a theoretical treatment of a weekly dose of 75 mg / kg live weight, divided into triplicate weekly doses for the first week (25 mg / kg live weight / hen), followed by A weekly dose of 25 mg / kg / hen was given once for several weeks. In practice, this amounts to 50g of yeast extract per 1000 hens. Hygienic conditions were good in this test.

Abstract

The invention concerns an agent containing a yeast derivative comprising 5'-nucleotides and/or peptides of at least 1000 daltons useful for preventing and/or treating cannibalism in wild animals, its preparation and its use.

Description

technical field [0001] The present invention relates to the prevention and / or treatment of cannibalism in domestic animals. Background technique [0002] Today's modern industrial livestock breeders strive to produce maximum quantities of meat, milk and eggs quickly and cheaply in dense production areas. In some of these intensive factory farms, syndromes such as cannibalism have been observed. The term "cannibalism" as used here is not limited to situations where one animal eats another, which is actually very rare. As used herein, the term "cannibalism" refers to any incident in which one animal injures another animal by biting or pecking. Thus, the term "cannibalism" includes pecking sometimes observed on poultry farms and in laying hens and game birds, as well as tail-biting (tail and / or ear biting) sometimes seen on pig farms. injuries), and aggressive behavior in ruminants. [0003] Cannibalism like this is detrimental to animal well-being and reduces production. ...
