The engineering company Budde, Schou & Co .____ '(54) Pig Growth Feed.

The invention relates to a feed for pigs to promote growth by continuous or repeated administration to the pigs of a polyacrylate in admixture with a feed preparation for the pigs.

In the recent development of pig breeding using feed preparations, a feed preparation with good feed effect has become necessary. Such a feed composition with good feed effect is a feed with high nutritional value, but the content of raw fibers is low, and thus the preparation hair has been a direct or indirect cause of inhibition of the growth of pigs. That is, when pigs are fed exclusively with feed preparations without the use of litter, they are significantly inhibited in growth.

2 141677

To counteract this inhibition of growth, methods have been developed in which, in addition to feedstuffs, raw feedstuffs such as bedding are used or where the feed can be freely eaten by the pigs. However, these methods are not practical because the feed effect of the feed preparation is diminished and the amount of faeces and fertilizers is increased and the workload is increased by feeding the pigs.

Antibiotics and similar substances have been widely used as feed additives mainly for the growth promotion and prevention of diarrhea. However, these additives cause some disadvantages such as staying in the live body of the pig and may cause resistant bacteria to be produced therein.

Furthermore, it is known, in accordance with Danish Patent Specification No. 103,705, to use monomer acrylic acid or a salt thereof as a growth promoter in feed.

The monomer and the polymers are quite different in their effect, with the monomeric acrylic acid salt passing easily through a semipermeable membrane, while the polymeric polyacrylate does not pass through a semipermeable membrane. This fact shows a crucial difference in the action of a living body, namely that the monomer is absorbed through the intestines and skin of animals while the polymer is non-absorbent.

Thus, since the mechanism of action is quite different in the two cases, one cannot draw conclusions from one case to another, and thus, by the knowledge of the doctrine of the Danish patent no. 103,705, one cannot predict anything about the growth-promoting effect of the present feed. .

Thus, the growth-promoting feed of the present invention is characterized in that it contains sodium polyacrylate or potassium polyacrylate in an amount of 0.05-1.5% by weight of the feed.

For the growth promotion of pigs, the polyacrylate is diluted in the form of a corn starch powder or the like and then administered to the pigs. Advantageously, a certain amount of polyacrylate powder is mixed as a feed additive with e.g. a feed substance as set forth in Table I of the following Example 1 and the powder feed formed is administered either as is, or after forming the polyacrylate-containing feed into pellets or granules using a pelletizer by a conventional method. The amount of polyacrylate administered according to the present invention varies depending on the state and body weight of the pig and is within the range of 0.05 to 1.5% by weight based on the weight of the feed, and the resulting polyacrylate containing feed is continuously or repeatedly fed to the pig. .

The present invention will be further illustrated by the following examples.

Example 1 1. Experimental methods (1) trial period: 99 days (2) experimental pigs: 45 landrace x Hampshire- «wine (half sows and half boars) with a weight of approx. 33 kg. These pigs are divided into three groups (3) feed and experimental groups: as a basic feed a practical powdered feed preparation is used. The pigs from the two test groups (treated groups) are fed with the base feed ten, mixed with sodium polyacrylate (hereinafter abbreviated to "ΡΑΗΛ") in quantities of 0.3¾ and 0.1% respectively, and the pigs from one group (control group) are fed. exclusively with the grand fodder. The components and composition of the basic feed are given in Tables I and II, respectively, and the classification of the experimental groups is given in Table ΪΙΧ.

2. Experimental results: the growth status of pigs from each group is given in Table IV. On the fourteenth day from the beginning of the experiment, the test pigs are examined, observing that the pigs from the control group (group 3) have been inhibited in growth. These pigs are separated. Both Group 1 and Group 2, which have been fed the ground-fed blended PANA, showed good growth status, and in particular for both groups, average body weight gain per day was high. day 11% or greater than in the control group as indicated in Table IV. Further, the feed conversion ratio also improved.
