“…За останні 10 років в Україні теж спостерігається чітка тенденція поступової заміни в селянських і фермерських господарствах пекінських і мускусних качок на мулардів, які потрапляють до нас із-за кордону (у вигляді інкубаційних яєць). У зв'язку з відсутністю в Україні власної племінної бази для отримання мулардів ми провели віддалені пошукові схрещування для визначення найбільш придатних варіантів міжродових гібридів качок із використанням вітчизняного генофонду (Shkurko et al, 2016;Shkurko et al, 2018;Bondarenko & Shkurko, 2019). На першому етапі досліджень у ФГ «Повіт-Агро» було вивчено господарсько-корисні ознаки дорослих качок різних видів і порід та проведено три пошукові схрещування для отримання вітчизняних мулардів: ♂ мускусна коричнева × ♀ степова сіра (схрещування № 1); ♂ мускусна коричнева × ♀ українська глиняста (схрещування № 2); ♂ мускусна біла × ♀ українська біла (схрещування № 3).…”

The article presents the results of the production efficiency test of the new intergeneric hybrid of ducks-mullards at the farm «Povit-Agro», Kyiv oblast, which was conducted in 2016. In 2015, economic indications of adult ducks were studied and three search crossings aimed at obtaining domestic mullards were conducted: ♂ musk brown × ♀ steppe grey (crossing No. 1); ♂ musk brown × ♀ Ukrainian white (crossing No. 2); ♂ musk white × ♀ Ukrainian white (crossing No.3). The studies have shown that in accordance with the live weight and slaughtering qualities, the best ducklings among all groups of ducks were obtained as a result of crossing No. 3. Therefore, the purpose of this work is to test the production efficiency of ducks-mullards growing of hybrid No. 3 for meat, in comparison to the original parental forms (musk white and Ukrainian white). Remote hybridization of musk drakes with ducks of domestic population (Ukrainian white) occurred by means of natural mating. Three groups of ducks (200 heads each) with respect to the degree of reduction of pre-slaughter live weight were arranged in the following sequence: intergeneric hybrid No. 3 (4207.0 ± 24.2 g), musk white (3805.0 ± 59.7 g) and Ukrainian white (3384.0 ± 21.3 g). The conducted studies have shown that ducklings of Ukrainian mullard (musk white ♂ × Ukrainian white ♀) are characterized by better growth energy, survival rates and slaughter qualities than their original parental forms. In this regard they are more suitable for the efficient production of dietary meat at farms as well at private households.

“…They are reared in both large-scale industrial and small courtyard conditions for such valuable products as meat, foie gras, fat, feathers and down, eggs, edible offals, and paws [2,3]. Goose production is a recognized branch of animal agriculture in various countries, including Ukraine, and has been improved by genetics, breeding, reproduction biology, and technology advances (e.g., [4][5][6][7][8][9][10][11][12][13]). However, it is hampered by a low egg hatchability [2,14].…”

One of the major problems impeding the sustainable development of goose production is low egg hatchability. Thus, it is imperative to develop more efficient ways to improve the hatching qualities of goose eggs. The present study aimed to investigate the effects of changes in the temperature regime of incubation on the availability of vitamins A (retinol) and E (α-tocopherol), as well as important elements of antioxidant protection in embryos and goslings. The initial heating of eggs at temperatures of 39 and 39.5 °C during the first 24 or 36 h was used as the main factor influencing goose embryo development. The dynamics in the content of antioxidant retinol and α-tocopherol were analyzed in the liver of embryos and goslings (up to 9 days of age) using the standard regime of incubation (at 38 °C) and the prior heating of eggs (at 39 °C and 39.5 °C) in the first 24 and 36 h of incubation. The obtained results provided new information about the effect of the initial heating of eggs on the function of antioxidants in the gosling’s body. It was confirmed that the age-related changes of retinol and α-tocopherol levels in goslings are similar to those found in chicks, ducklings, and turkey-poults. In addition, the effect of an egg’s weight on hatchability was established, with the hatchability of eggs in the medium weight class being higher than that of smaller and larger eggs. The efficiency of the redistribution of retinol from the yolk to the liver in day-old goslings was higher by 6% when exposing eggs to a temperature of 39.5 °C for 36 h. The initial heating regime at 39.5 °C led to an increased hatch of goslings, and to the evenness of their hatch from eggs of different weights, approaching the hatch values of the medium class. Overall, the α-tocopherol concentration in the liver of embryos and goslings, using the starting heating of eggs, was higher than that with the standard temperature mode of incubation. At the same time, the hatch rate of goslings increased by 9–13%, and the hatchability of eggs by 10–16%. For use in the practice of hatcheries and breeding poultry farms, it is recommended that goose eggs are heated for 36 h at 39.5 °C.

In the article, according to international statistics (FAOSTAT), the dynamics of the duck population and the production of duck meat in the world, in Ukraine and in certain countries in the period 2016-2020 are given. It is established that in 2020 the duck population in the world slightly decreased (by 0.75%). At the same time, the largest number of ducks is concentrated in China – 62.7 and 60.6% of the world's population, respectively, in 2016 and 2020. Ukraine took tenth place in this ranking in 2020. With a slight fluctuation in the number of ducks in the world, a tendency to its increase was noted in the production of meat – by 37.8% compared to 2016. However, in Asian countries, ducks are bred not only for meat, but also for eggs, which are used as food. Duck egg consumption is about 10-30% of total egg consumption in China and Southeast Asia. Among the population of South-East Asian countries, such a product as "balyut" is popular, which is prepared using a duck egg with an embryo about 18 days old. Based on the analysis of data from various literary sources, the issue of duck keeping systems in different countries of the world and Ukraine is highlighted. Since ducks belong to waterfowl, along with the intensive technology of keeping them (in closed rooms with a microclimate that is controlled and regulated), extensive technology is also used – using walks, including water ones. In Ukraine, 97.5% of the duck population is kept in public farms, and therefore the main system of their keeping is extensive. The importance of complete feeding of ducks is also indicated, recommendations are given regarding the nutritional value of rations depending on the age of the bird. In Ukraine, the largest farm engaged in the industrial production of duck meat is the Poultry Brood Plant “Korobivskyi” JLLC of the Zolotonosha district of the Cherkasy region. The production of duck meat using intensive technology involves the use of high-production crosses, the keeping of poultry in poultry houses with a regulated microclimate and complex mechanization and automation of technological processes, and the feeding of poultry with complete ration compound feed.
