“…Fertility and hatchability are important economic factors that represent major components of reproductive performance ( Salamon, 2020 ). Paternity efficiency ( PE ), as a manifestation of fertility, refers to the percentage of chicks produced by a sire in relation to the total number of chicks produced in a flock ( Donoghue et al., 1999 ; Ely et al., 2017 ).…”

The purpose of this study was to investigate the influence of social rank ( SR ) on paternity efficiency ( PE ) in competitive mating flocks of geese. Thirty ganders and 150 geese (Zi geese, Anser cygnoides L.) aged approximately one, were divided into 3 groups. Flock 1 included 10 ganders and 50 female geese, flock 2 included 11 ganders and 55 female geese, and flock 3 included 9 ganders and 45 female geese. The frequency of the agonistic behavioral interactions ( ABI ) of the ganders and mating activity ( MA ) were video recorded in each flock. The SR of each gander was determined by the frequency of ABI with a score of 1 to 3 (1 being the dominant and 3 the most subordinate). To clarify the difference between being dominant and submissive, we collapsed rank 2 and rank 3 into a “subordinate” category. In total, 280 eggs were collected, and 219 goslings were hatched. Parent–offspring relationships among 399 individuals from the 2 generations were identified via 20 microsatellite markers, and the PE of each gander was calculated. There was no significant difference in individual body weight and semen quality factor among the different SR groups (dominant and subordinate), and the SR of the ganders was significantly correlated to PE for the 3 flocks. Goslings of high-ranking ganders contributed 48.68% in flock 1, 37.50% in flock 2, and 47.62% in flock 3. Approximately 45% of all goslings were sired by the 7 dominant ganders of the 30 total ganders across the 3 flocks. As SR has been shown to be heritable in geese, the selection of high-ranking ganders might be an effective way to improve reproductive efficiency in commercial geese flocks.

“…The goose industry in China is especially prominent with an annual output accounting for approximately 95% of the world's total production: with over 600 million geese slaughtered and more than 250 million tones of meat produced [1]. Due to increased market demand for day old goslings in the goose industry and the seasonality of the goose production, the improvement of reproductive performance in geese is crucial [2]. To optimize the reproductive performance and for high economic returns, balance between two major key reproductive factors, i.e., hatchability and fertility, is inevitable.…”

“…The success of incubation during this period depends primarily on the technology for the production of hatching eggs and their quality. Inadequate eggs lead to the formation of weak embryos, which die at the beginning of development after the formation of their circulatory system [7]. The number of embryos that died during this period in groups was at the same level.…”

This article shows the results of chicken eggs incubation by IUP-F-45 and BioStreamer 165HD. There were two different types of machines during two-lots of eggs incubation. The BioStreamer 165HD is equipped with such feature as flexible incubation environment tuning according to its technology of embryo feedback. The sensors control the temperature inside machine by using the temperature of egg shells. Also there are sensors which can monitor the humidity level by controlling and predicting the humidity loss of each egg lot and using the narrow-hatching window technology. The incubators are managed by controller and connected to one computer network. The eggs are set to cellular structure incubation tray. The pulsators are equipped with five wide blades to ensure the required air flow rate. In addition, the roof vents have been improved. The power of the heating elements has been increased, which provides a quick heating time for all eggs at the beginning of the incubation cycle. The larger diameter of the cooling coil creates a wider overall cooling surface. As a result of the research, it was found that the use of the BioStreamer incubator made it possible to increase the hatchability of eggs, to carry out the simultaneous hatching of young brood, reducing the hatching by 5.5 hours, to increase the yield of conditioned young chickens by 0.9% and its quality, to obtain a greater amount of meat products from broilers: the average weight of chickens increased by 2.7 per cent, the safety of brood - by 3.6 per cent.
