Hatching Eggs

In seed production, the success of spawning and egg production is very important to mantain the cultivating sustainability. The quantity and quality of the blacksaddled coral grouper eggs should be properly manipulated to produce the higher values. The purpose of this study was to determine the effect of different temperatures on the results of hatch success (embryo development, incubation time, hatching rate and larvae abnormality). The eggs used were obtained from natural spawning and collected with egg collector. The fertilized eggs were incubated in four pieces of container and were treated with different temperatures of 26°C, 28°C, 30°C, and 32°C which each treatment was repeated 3 times. The incubation equipment with automatic temperature control was used in this treatment. The results showed that the eggs which were incubated at 32°C produced a faster of embryonic development and hatch within 14 hours while the temperature of 26°C took 18 hours to hatch. However, the temperature of 32°C resulted in low egg hatchability, with 60.29%, as well as the abnormalities of 8.42%. The best temperature of each treatment was obtained at the incubation temperature of 30°C, whereas the phase of the hatch was achieved within 15 hours, with egg hatchability of 92.25% and the abnormality of 6.29%. From these results, it can be concluded that the optimum incubation temperature for Blacksaddled coral grouper was 30°C. Keywords: hatching, egg of Blacksaddled coral grouper, Plectropoma laevis, incubation temperature.

SummaryThe flameback pygmy angelfish Centropyge aurantonotus, highly appreciated and valued by the aquarium market, is heavily harvested and traded. Temperature is one of the abiotic factors that has the most influence on fish development, especially in the early stages of life. For captive production, it is essential to know the appropriate environmental parameters for each species. In this sense, this study aimed to evaluate the influence of temperature on the embryonic development and hatching rates of C. aurantonotus incubated at six different temperatures (20, 22, 24, 26, 28, 30°C). Embryonic development events were very similar in terms of morphological and chronological characteristics compared with other species of the genus Centropyge. Incubation time was inversely proportional to temperature. The treatment at 22°C required twice the time of that required by 30°C treatment for hatching to occur. The best incubation temperature range was 24–28°C. Values below 22°C and at 30°C showed lower hatching rates compared with other treatments. Based on these results, the recommended temperature at which to incubate C. aurantonotus eggs is between 24–28°C.

Abstract Theoretical and applied aspects of the concept of using biomimetic protective coatings GREEN ARTICLE (ARTIficial cutiCLE) in the poultry industry, namely in the production of table and hatching eggs, are developed. The basic matrix component of the protective coatings GREEN ARTICLE is chitosan, an environmentally friendly, inexpensive, and harmless material. It is experimentally proved that electrochemical and ultrasonic technologies for modifying a solution of chitosan in peroxide compounds (peracetic acid and hydrogen peroxide) with nanoparticles of oxides like titanium, iron, zinc, and metals, such as titanium, copper, and calcite, allow to create protective coatings of double action in accordance with the technologies: (a) extending the shelf life of table eggs, food green article (FGA) and (b) preventing contamination of hatching eggs with pathogenic microflora, increasing the hatchability of eggs, and the quality of chicken, hatching green article (HGA). In the technology of storing table eggs, artificial cuticles based on chitosan FGA are characterized by the following characteristics: increased thickness of 6–10 µm, low gas and moisture permeability, and high biocidal activity against pathogenic bacteria and viruses. It is shown that the use of FGA technology in the production of table eggs can extend the period of transportation and storage of products by 33–35 days at a temperature of 24°C and maintained a grade A (Haugh unit = 71–60) through the entire 35 days period. The technology HGA reduces the rate of contamination of hatching eggs with pathogenic microflora by 99.29–99.7%, while increasing the egg hatching rate by 2.3–11.6% compared to the control, depending on the cross of the poultry and the storage conditions of the hatching eggs. It is important that these technologies have a great prospect for application in countries that develop green technologies for the production of poultry products.

Abstract Over the last decade, there has been an increased consumer interest in niche food products with special aroma and flavour, and rich in nutrients. Poland has a large (19 lines) and valuable collection of laying hens enrolled in the genetic resources conservation programme. Research to date has shown these hen breeds to vary in phenotype, productivity, and biological quality of hatching eggs and meat. A significant problem in using hens for both egg and meat production is that the number of unwanted cockerels increases with increasing intensity of egg production. This problem can be overcome by castration of cockerels. Roosters were sterilized long before Christ, first as a religious ritual and then to increase the body weight of birds. The qualities of capon meat were noticed much later when it turned out to be more delicate, juicy and tender compared to rooster meat. The aim of this paper was to review the literature on capon production, including the effects of castration on the bird’s body and on the quality of meat obtained.

The aim of the studies was to conduct a veterinary-hygienic assessment of changes in the eggs productivity of laying hens, after the use of the “Prinarovskaya supplement of fish (DKR)” in their main diet, which is a homogeneous dry mass made from chilled river fish, by-products of fish processings, as well as grain products (wheat bran). The method of production of the additive in-cludes the following steps: grinding, cavita-tion heating and subsequent drying of the resulting mixture. The studied supplement contains a number of amino acids, vitamins and minerals, etc. The object of the study were laying hens of the LomannLsn-Classic breed at the age of 131 days. “Prinarovskaya DKR” were introduced into the diet of ex-perimental laying hens: of the 1st experi-mental group 8 g of “Prinarovskaya DKR” were introduced per 100 g of the main ration (RR); The 2nd experimental group - 6 g. DKR to main ration; 3rd experimental group - 4 g. DKR to main ration; the control group was fed only main ration - feed PK1-1G_1227 (GOST: R 51851-2001). A veteri-nary-hygienic assessment of the quality of eggs, obtained from laying hens, when feed-ing a new feed additive “Prinarovskaya” was carried out. We kept daily records of laid eggs by groups, the period of the beginning of oviposition. The egg production were calculated of the initial and middle laying hens , the egg production intensity for 120 days. To assess egg productivity, the weight of laid eggs, the egg mass for a certain peri-od of egg laying, and the feed costs per 10 laid eggs were determined. Organoleptic, physical, and chemical methods were used to evaluate egg quality. Egg mass is an important indicator of egg nutrition. GOST 31654-2012 "Food eggs. Technical conditions ”, as well as the requirements for chicken hatching eggs, the minimum weight of food and hatching eggs (45 g) is indicated, below which the imple-mentation and incubation of eggs is not rec-ommended [1]. In studies, the following indicators were taken into account: large and small diameter of eggs, egg density, egg shape index of laying hens of different groups. To assess the state of the internal contents of the egg after opening, the follow-ing indicators were taken into account: pro-tein mass, yolk mass, shell mass, egg vol-ume. An external examination of the eggs as-sessed the condition of the shell, the pres-ence of cracks, growths and depressions. The study indicates a positive effect of the feed additive "Prinarovskaya" on the egg produc-tivity of birds in all periods of egg laying

The aim of our research was to increase the productive and reproductive qualities of geese breeders by crossing the white Hungarian and Kuban rocks. To achieve this aim, we should solve the following problems: to study the economically advantageous features of geese flocks of different genotypes and to calculate the cost-effectiveness of the research results. Materials and methods. The experiments were carried out in the Limited company “Bashkirskaya ptitsa” of Blagovar district of Bashkortostan in 2009-2012 by geese flocks of white Hungarian, Kuban breeds and their crosses. To study the productive and reproductive qualities of geese flocks we formed four groups of 64 head of adult geese of first year at the rate of 3 to 1 gander goose. The first group was equipped with Hungarian white goose breeds, the second - the Kuban , the third - a cross between those, obtained by crossing the white Hungarian geese ganders with Kuban, and the fourth - a cross between the Kuban gander and white Hungarian geese. The research was carried out for 150 days. The process parameters and feeding of geese corresponded to VNITIP recommendations. According to the research, we found that the geese of III trial group (♂Hungarian × ♀ Kuban) outnumbered white peers of Hungarian breed and other groups in egg production by 9.6 and 2.2%, respectively, with 3.9% yielding Kuban. The highest content of carotinoids, vitamin A and B2 were found in the eggs of hybrid geese of III group, which amounted to, respectively, 16.05 mkg/g, 9.31 and 8.73 mkg/g. The highest number of conditional geese of first category had also cross-bred geese of third experimental group (♂Hungarian × ♀ Kuban) - 1,447 heads or 85.7%, which is 4.3, 5.9 and 2.2 % had more than a white Hungarian, Kuban breeds of geese and other crossbred groups. Output. Thus, due to the high egg production, the quality of hatching eggs and day-old chicks, the breeding of hybrid geese, obtained in crosses with a white Hungarian geese with Kuban rocks, yielded additional revenue of 119,751.7 rubles and increase profitability by 11.91% , compared with the parental forms Kuban breed geese.

Groupers were known as a high economically marine commodity and in order to support groupers production, the seed availability was the most important. Eggs are still as limited factor in hatchery production, for this reason the success of eggs transportation is one as base of successful production of seed. Planning on hatching time of eggs through different incubation temperature was an option to solve that problem. This experiment was aimed to find out the optimum temperature for groupers eggs and the minimum temperature to arrange incubation time and to plan the hatching time. Fertilized eggs were incubated into three beaker glasses of 1 liter in volume with the density of ± 250 eggs/liter. The incubation was done under laboratory condition at controlled temperature, i.e. (A) 21-22 ºC, (B) 24-25 ºC, (C) 27-28 ºC and (D) 30-31 ºC. The eggs that used were including orange spotted grouper (Epinephelus coiodes), brown marbled grouper (E. microdon), tiger grouper (E. fuscoguttatus) and humpback grouper (Cromileptes altivelis). Investigated variables were embryonic development pattern, incubation time and hatching rate. The result showed that the eggs incubated in temperature range of 24-31°C had the normal sequence of embryonic development pattern, but in temperature of 21-22°C performed irregular sequence and the embryonic development stopped at blastula or gastrula stage or even the eggs could still develop but the body of hatched larvae were abnormal. In lower temperature incubation, the incubation time was longer and the hatching rate of eggs was lower than those in higher temperature. Therefore the optimum temperature for incubation of orange spotted grouper, marbled grouper, tiger grouper and humpback grouper eggs ranged between 24-31 ºC, while the lowest possible temperature was 24 ºC.Keywords: incubation temperature, embryonic development pattern, grouper eggs, hatching rate
