Description

 CLOSED CIRCUIT SYSTEM FOR LIQUID NUTRITION, HYDRATION, BENEFICIAL MICROBIO INOCULATION AND CARRIER FOR OTHER BENEFICIAL AGENTS FOR THE BIRTH UNTIL THE TIME OF EXPEDITION.

FIELD OF INVENTION

This patent application is for a closed loop for liquid nutrition, hydration, beneficial microbiota inoculation, and beneficial element carrier for newly hatched birds during the hatching phase up to the time of dispatch, that is, during the beginning of hatching until the moment of bird dispatch, the field of the invention being directed to the bird hatchery segment.

BACKGROUND OF THE INVENTION

Fertile bird eggs go through the incubation process and are transferred to so-called hatcheries, usually with 456 hours of incubation and the first hatching birds begin around 480 hours of incubation and the process usually ends. with 504 to 510 hours of hatcheries. Therefore, the first hatched are the birds that suffer the most from water deprivation, dehydration and excess period within the hatcher.

Several studies suggest that early-hatched, hydrated, newly hatched birds have better survival and better performance during productive life and greater disease resistance.

Thus, the present invention emerges as an innovation not only to provide better animal welfare and comfort, but also early nutrition, improve pathogen immunity and increase the survival and future productive performance of the bird.

TECHNICAL STATE In the path of technological development several initiatives try to improve the conditions of comfort, hydration and nutrition of prenatal or neonatal individuals.

[0006] One of the first attempts at neonatal nutrition took place in the Netherlands with the Dutch company Hatchtech's HatchBrooder system, which consisted of a transfer of newly hatched chicks to independent and exclusive structures to receive these birds and keep them in water, food and nutrition. solid, heat and light for at least two to four days after hatching. Difficulties have arisen regarding the size and cost of structures that should almost double in size and do not solve the problem of the birth window that remains as it is.

Another recent attempt with the Dutch company Hatchtech's HatchCare system is to use the same structure as the hatchers but employing a double bottom hatch where newly hatched birds fall through holes in the second part of the tray and have access there. the food the solid food, water and light. The difficulties with this system lie in the fact that food and water are exposed to the environment of heat, humidity, down and contamination, and birth trays must be unique and many hatcheries must replace the set of birth trays with unique trays.

[0008] A recent attempt at in ovo nutrition, where in ovo vaccinating machines are used at the time of egg transfer and injecting into the beneficial nutrient amniotic fluid and microbiota. The difficulties with this system is that many nutrients can cause embryonic mortality and the amount injected is usually very small, not more than 0.1 to 0.2 ml, losing the nutritional or hydrating effect.

The state of the art is known from document MU7502016-5, filed on 08/09/1995 and published on 14/04/1998, under the heading of "Thermal Semi-Automatic Incubator", which describes an incubator which The objective is to increase the hatching percentage in the hatching of eggs and to facilitate the obtaining of chicks or chickens for breeding. In the process of using the 'Semi-automatic Thermal Incubator' the user opens the door, turns on the arrow, fills the water reservoirs, puts the plugs and regulates the temperature in the thermostat using the barometer. After reaching the ideal temperature, lay the eggs and turn them as directed. The user must open the tampons on the indicated days and spray the eggs with water to facilitate the cracking and breaking of the shell. The incubator should only be turned off 12 to 24 hours after hatching has completed.

Another document of the state of the art is PI9407646-1, filed on 22/09/1994 and published on 21/01/1997, under the heading "APPENDIX FOR THE CREATION OF SPENDING GROWTH RATE. Processes for Operating a Computer; Process for Determining the Use of Nutrient Efficiency in a Population; and Computer System for Determining the Effectiveness of Nutrients for a Population Based on the Middle Population. The invention describes an apparatus and process for determining the earliest possible time for a living creature to reach its maximum growth rate. This information is then used to calculate optimal parameters for maximum return or investment. A computer determines the optimal number of birds per flock, type and amount of feed, length of time between hatching and sale to the feed processor, etc. The computer consists of a microprocessor, random access memory, storage device, a keyboard, a computer screen, a printer, and a math coprocessor.

[001 1] This document reported in the previous item aims to obtain a maximum growth rate in the shortest possible time, making use of a microprocessor system for the calculation of parameters considered ideal. However, like other known equipment, it does not solve the problem of beneficial microbial nutrition and colonization, thus not meeting the objectives of the present invention.

Problems inherent in the state of the art

Currently, there is a birth window between 24 (twenty four) and 30 (thirty) hours between the first bird to hatch (hatch) and the last bird to be drawn from the hatcher. Thus, the birds dehydrate and are delayed to receive nutrition, hydration and beneficial microbiota, adding to this the preparation time of the birds, with selection, vaccination and pre-expedition waiting room, which can reach more than 12 (twelve). or 16 (sixteen) hours.

Technically, the slowness of this process causes dehydration, depletion and use of liver and yolk nutritional reserves, reducing survival, counteracting animal welfare and impairing the bird's future productive performance.

PURPOSE OF THE INVENTION

It is an object of the invention to provide the technology of a closed-loop system for liquid or semi-liquid nutrition, beneficial microbiota hydration and colonization, and carrier of other beneficial factors for newly hatched birds, from the hatch to the moment of hatching. expedition, ie during the beginning of hatching until the time of dispatch of the birds.

ADVANTAGES OF THE INVENTION

In addition to those evident from the foregoing description, the following advantages may also be highlighted:

- Safe closed-loop system for nutrition, hydration, and carrier of any factors that promote improvement and response of birds. Example of immune response and disease resistance, hydration, growth factors of newly hatched birds. - Increased bird survival, improved animal comfort and welfare, reduced dehydration losses, immediate nutrition of enterocytes, reduced bird exhaustion due to early consumption of reserves, tissue hydration, immediate inoculation of beneficial microbiota.

In the productive aspect, higher survival rate, higher weight gain, better feed conversion and higher resistance to pathogens are expected; more productive and healthier birds.

DETAILED DESCRIPTION OF THE INVENTION

[0018] CIRCUIT SYSTEM CLOSED FOR LIQUID NUTRITION, HYDRATION, INOCULATION OF BENEFICIAL MICROBIOTA AND CARRIER FOR OTHER BENEFICIAL AGENTS, DURING THE BIRTH PHASE UNDER THE APPLICATION OF THIS PURPOSE, comprises a system that applies to phases (C) and (D) of the flowchart of Figure 3, particularly from sanitation of hatcher rooms, where the trolleys (1) with trays (2), to the dispatch of chicks (3) ). Only for a better understanding of an incubation process does it begin, in phase (A), or egg room (4) where eggs arrive from production farms (5) and classification and storage occurs in temperature controlled rooms (6).

Step (B) is called egg incubation (7), where there are incubators with controlled temperature and humidity (8) and also the transfer to hatcheries at 19 days (approximately 456 hours) (9). that at this stage, vaccination is done in ovo.

In step (C) is where the system of the invention comes into operation, so-called hatcheries (10), where the birth of baby chicks begins with approximately 480 (four hundred and eighty) hours of incubation (11); birth is completed between 504 and 510 hours of incubation (12).

In step (D), or expedition (3), the system of the invention remains in use, nourishing the birds so that baby chicks are allowed to deprive themselves in the drawing, preparation and dispatching step (3B). of water for another 12 hours.

The system according to the invention, particularly in steps (C) and (D), utilizes the hatch (10) housing the carts (1) with trays (2) disposed inside the hatch (10) where it circulates in a circuit. closed (13) for a solution capable of promoting nutrition / hydration and microbiota inoculation for newly hatched birds or any other factor considered beneficial to birds, and the circuit receives illumination (14) through a light-generating source that may emit light. in the most appropriate spectrum the birds, while the solution leaving the interior of the hatcher (10) passes through a heat exchanger (15), where a pump (16) transfers this solution to the upper reservoir (17), from where continues returning to the closed loop (13).

Each said tray (2) has a conduit (18) of nourishing liquid that passes throughout the interior of said tray (2) in which are distributed the nipples (19) where the birds contained in the hatcher (10) access to nourish or hydrate or receive in liquid or semi-liquid form the specific beneficial factors.

The hatching set inside (10) has a system of, variable temperature between 32 ° C to 34 ° C, and relative humidity of around 75%, Therefore at the time of recirculation of nutrient solution it is necessary the installation of a heat exchanger (15), where it is cooled to an age-appropriate temperature range and the conditions required by baby chicks, from which a pump drives this liquid to the upper reservoir (17), where the nutrient solution returns to the closed loop of the invention.

[0026] With the present invention, the closed system maintains the characteristics of nutrition, hydration and other benefits to newly hatched birds up to 22 to 30 hours after birth considering the period within the hatcher.

The product used in this closed loop operates using a preferred nutritional composition, which gathers all nutrients for feeding and hydration of baby birds, ensuring not only survival while at the hatch, but also when pre-shipment and, after dispatch, the specific times in each of these phases being specified throughout this descriptive report. The nutritional composition in a preferred embodiment is shown below, namely:

 bird performance

However, the same system is adapted to complement the deprivation period that also occurs in the pre-dispatch phase of the birds, the nutrition is adjusted to a waiting time at dispatch which can be at least 12 to 16 hours. Therefore, the system is designed to operate both in the hatching phase and also in the baby chick room (waiting / dispatch), which will ensure safe transport and survival and welfare of the birds also in the waiting and transport processes.
