RU2380898C2 - Method for treatment of incubation eggs in order to improve hatching rate and safety of young birds - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: method for correction of embryonic vitality and natural resistance of chickens of line K8 of cross "Competitor-3" - paternal line, for the first six weeks of growth, including treatment of incubation eggs, when transferred for hatching. Eggs are treated in the first day of incubation directly prior to setting, and eggs are treated in the 19^th day of incubation in amount of 80 ml per 140 pieces of incubated eggs. Prior to their setting into incubation cabinet, 0.25% solution of limontar is used, and after transfer for hatching - by 0.55% solution of limontar.

EFFECT: invention provides for stimulation of embryogenesis, natural resistance, improved hatching rate and hatchability of eggs.

Description

The invention relates to agriculture, in particular to poultry farming, and specifically to methods of incubating treatments of eggs with natural metabolites (succinic and citric acids), which have anti-stress, immunostimulating and immunomodulating properties that increase the nonspecific reactivity of the body, hatchability of eggs, and productivity of poultry.

To stimulate the growth and development of poultry, it is effective to use natural metabolites (1), namely succinic acid. Method (2) (the use of solutions of the complex of succinic acid and glycine preparations by double treatment of the incubation eggs of the Smena-2 cross: pre-incubation and when transferred to the conclusion of 0.25 and 0.55% solutions, respectively) we accept as a prototype.

The objective of the invention is to stimulate embryogenesis, natural resistance, increase hatch and hatchability of eggs with the drug Limontar, which is a mixture of citric and succinic acids. Succinic acid increases the energy production of the respiratory chain of mitochondria, accelerates the synthesis of ATP, and also restores the potential of the mitochondrial and cell membranes.

EFFECT: increased energy production of the respiratory chain of mitochondria, accelerates ATP synthesis, and also restored the potential of mitochondrial and cell membranes.

The technical result is achieved by the fact that the method of correction of embryonic viability and natural resistance of chickens of the K8 line of the Cross-Competitor-3 cross - the paternal line in the first six weeks of rearing includes processing of the hatching eggs upon transfer to the conclusion, and the eggs are processed on the first day of incubation immediately before laying and they process eggs on the 19th day of incubation in the amount of 80 ml per 140 pieces of incubated eggs, with 0.25 being used before laying them in an incubation cabinet, and when transferring to conclusion 0.55% solutions imontara.

The proposed method is characterized in that in veterinary practice separately used succinic and citric acids.

The proposed method is illustrated by the following examples of the interaction of organic acids (see table 1-13).

The specified method 1 (the use of 0.02-0.2% solutions of succinic acid before incubation) can increase the hatchability of eggs by 4-6% compared with the control.

The proposed method for processing hatching eggs is economical because small concentrations of the drug are required, limontar is highly active and used in medicine, not toxic, because shown as a means to increase the nonspecific reactivity of pregnant women, improve its adaptive and compensatory-protective capabilities in order to prevent complications of hypoxia, fetal malnutrition and miscarriage.
