Abstract

The cage is made from synthetic materials, e.g. fiberglass, polycarbonate, PVC and acrylic. The cage has a 29.5 centimeter (cm) wide dry part (A), 4 cm wide feeders (3) separated from the posterior and anterior, a 6 cm high side part, and a 30 cm wide wet part (B). Shelters (1,2), each 12 cm wide and 6 cm high, are provided on each side of the cage. The wet part consists of a pool with three water levels: a 4 cm wide and 1.5 cm deep shallow area (4) to each side, a 6 cm wide and 2.5 cm deep deeper area (5) and a 10 cm wide and 5.5 cm deep central area (6).

State of the art

There is a patent pending (P200102111) -of the same inventors who present this- on the system of fattening of the Iberian frog in its initial phase of fattening.

Explanation Installations Cages (Fig. 1, 2, 3, 4 and 5)

Made primarily with fiberglass or other synthetic materials such as methacrylate, polycarbonate, PVC, cement, fiber cement, etc. They have a wet part located in the center of the cage and a dry part on both sides of the previous. Specifically:

-

Dry part (letter A in Figs. 1, 2 and 3): they are two equal zones located to both sides of the wet part. Each of them should measure 29.5 cm of width and contain:

?

A feeder (number 3 in Figs. 1, 2 and 3): a small excavation in the cage material 0.5 cm deep, 4 cm wide and length equal to that of cage but separated 4 cm from the walls front and back of it.

?

Four shelters of two types (numbers 1 and 2 of Fig. 1 and Figs. 4 and 5): two are located between the wall of the cage and the feeder (number 1 of Fig. 1 and Fig. 4), and two others are located between the feeder and the pool (number 2 of Fig. 1 and Fig. 5). All are pieces of "remove and put" made of methacrylate (or similar) whose Length will be the same as that of the cage. Some (Fig. 4) consist of a rectangular piece with a width of 12 cm, and with supports (number 7 of Fig. 4) 6 cm high that will be arranged in Every corner Others (Fig. 5) located closer to the pool than the above are the same as those already indicated: a rectangular piece 12 cm wide with 6 cm high stands (number 7 of the Fig. 5), but with another rectangular side piece directed towards the pool (number 8 of Fig. 5), of the same height as the brackets

-

Wet part (letter B in Figs. 1, 2 and 3) located between the two dry zones: it consists of a 30 cm wide pool with three water heights; in the center is the deepest portion (number 6 in Figs. 1, 2 and 3) 10 cm wide and 5.5 cm deep; sideways two areas with less depth (number 5 in Figs. 1, 2 and 3) of about 6 cm wide and 2.5 cm deep, and turn laterally the two shallowest zones (number 4 in Figs. 1, 2 and 3) of about 4 cm wide and 1.5 cm deep.

Each cage has water inlet and outlet, a at each end (number 9 in Figure 3), to have a continuous water flow of about 100 milliliters per minute.

In each cage there are frogs that have passed the initial phase of fattening, with a density of about 75 Animals per square meter.

At least once a week the cages are cleaned with soapy products and sanitized with products disinfectants

Enclosure

The cages are arranged in enclosures with temperature controlled conditions (18-22 ° C) and photoperiod (12 hours of light-12 hours of darkness). These enclosures must have a water source to provide each cage with a continuous flow and must be isolated from outside, to maintain controlled conditions and to prevent the entry of natural predators, as well as others animals and even for the arrival of sounds and smells strangers.

Feeding

The feeding is carried out with feed extruded and pelleted about 4 mm in diameter and about 6 mm in diameter length. The feed is available in the feeders every 4 days following the routine (4-day cycles) indicated in the Table I.

TABLE I Routine to follow with the cages: 4-day cycle that it is repeated as many times as necessary

Fattening

Frogs should have an average weight of more than 2 grams per animal at the beginning of the fattening period, performing periodic checks to check the evolution of the weight of the animals.

Description of cage drawings

Five figures are presented with different cage perspectives (Figs. 1, 2 and 3) and others (Figs. 4 and 5) With both types of shelters.

Inside the cages the different ones are represented components thereof: the dry part (letter A) and the part wet (letter B), as well as their constituents: shelters (numbers 1 and 2), feeders (number 3) and pool with their three heights (numbers 4, 5 and 6). The number 9 (in Fig. 3) represents the water inlet and outlet hole.

The shelters (Figs. 4 and 5), which are of two types, they are removable pieces that have at least three supports (number 7) for attachment placed in the manner in which Look in the picture. The shelters differ in that some (the of Fig. 4) consist of a horizontal piece and supports, and the others (those in Fig. 5) in addition to the horizontal piece and the brackets have another side piece (number 8).

The cages may have the desired length but always attending to an average density of animals of 75 frogs per square meter.

Industrial application

Industrial frog farming is an activity that arouses interest in future producers due on the one hand to the demand for frog meat (mainly of its legs) and for another, to the demand of live animals for restocking (whose populations in the natural environment have suffered a significant decline) as for teaching and research purposes. It can also exist other markets: for frog skin, to obtain flour animals, oils, etc.

This patent is applicable in industries interested in frog captive breeding. With her the product is available at any time of the year and in the best sanitary conditions.

Claims (2)
