The effect of sex and slaughter age on growth, slaughter, and carcass characteristics in Lindovskaya geese reared under breeder conditions

Abstract

The study was conducted to determine growth, slaughter, and carcass characteristics of Lindovskaya geese. While a total of 237 goslings, 101 males, and 136 females were used to determine their growth characteristics, 16 male geese in total were used for the detection of the slaughter and carcass characteristics. Each slaughter group (12 weeks and 16 weeks old) consisted of 8 male geese. It was determined that the effect of sex on body weight values by week was significant (P < 0.05). In addition to this, the body weights of male geese were higher than the body weights of the female geese in all weeks. In the study, it was determined that the effect of the slaughter age on the weights of slaughter, head, blood, intestinal fat, and abdominal fat was significant (P < 0.05). Additionally, the values of the geese slaughtered at 16 weeks were higher compared to the geese slaughtered at 12 weeks. It was detected that the effect of slaughter age on the weight of the hot carcass, cold carcass, neck, breast and back, and other parts were significant (P < 0.05). Moreover, it was concluded that these values increased as the slaughter age increased. As a result, it can be said that slaughter age at 16 weeks was more preferable than at 12weeks under breeder conditions. Additionally, it has been revealed that Lindovskaya geese need to be reared under controlled conditions, with regular care and feeding, to obtain better results.

Effect of parent flock age on hatching, growth rate, and features of both sexes goose carcasses

“…Research on the influence of the sex of Czech Goose and Eskildsen Schwer on slaughter traits also confirmed the differences, including the slaughter weight ( Uhlírová et al, 2018 ). In the case of Lindovskaya geese, similar results were shown between sex ( Akbaş et al, 2020 ).…”

Effect of crossbreeding and sex on slaughter performance and meat quality in Xingguo gray goose based on multiomics data analysis

“…Recent research has found significant differences in muscle and carcass fat content between male and female geese ( Lisiak et al, 2021 ). Such differences, including slaughter weight, were also confirmed in a study on the effect of sex on slaughter characteristics of heavy Czech and Eskildsen Schwer hybrid geese ( Uhlirova et al, 2018 ), and similar results were observed in male and female Lindowskaya geese ( Akbaş et al, 2020 ).…”

Slaughter and Carcass Traits of Gray Hungarian and German Mast Geese

“…The overall mean of feather weight determined as 294.62 g in Gray Hungarian geese and 215.06 g in German Mast geese werelower than those of native breeds reported by Tilki and İnal (2004), similar to those of reported by Boz (2019), and higher than those of reported by Kırmızıbayrak and Önk (2011). The mean blood weight in Gray Hungarian and German Mast geese was lower than the values in the study of Akbaş et al (2020), Önk (2011), andBoz (2019), and similar to the values reported by , Saatcı et al (2009), and Kırmızıbayrak and Kuru (2018). It is suggested that these differences may be due to possible differences in genotype, age, or duration of bleeding.…”

“…Hot carcass dressing percentagevalues were 66.27% and 67.99% in Gray Hungarian and German Mast geese, respectively. In literature, carcass dressing percentage in geese generally varies between 60-73% and increases with age Kırmızıbayrak and Önk 2011;Akbaş et al 2020;Boz and Sarıca 2021). The carcass yield of approximately 67-68% obtained in the present study is considered to be at an acceptable level considering the nutritional conditions and age.…”
