“…Geese reared under intensive conditions are called broilers. This type of production is practiced in Turkey ( Isguzar and Pingel, 2003 , Tilki et al., 2005 , Tilki et al., 2009 , Saatci et al., 2009 ), China ( Liu et al., 2011 ), and the Czech Republic ( Tůmová and Uhliřová, 2013 , Uhliřová and Tůmová, 2014 , Uhliřová et al., 2018 , Uhliřová et al., 2019 ). In Poland, production of goose meat based on intensive rearing is not widespread, with one reason being the lack of tradition for farming broiler geese.…”

“…The goose carcass traits are affected by many different factors including rearing system ( Liu et al., 2011 ), genotype ( Isguzar and Pingel, 2003 , Kapkowska et al., 2011 , Tůmová and Uhliřová, 2013 , Uhliřová and Tůmová, 2014 , Uhliřová et al., 2018 , Uhliřová et al., 2019 ), and variety ( Boz et al., 2019 ). Also values of some physicochemical parameters of breast and leg muscles change differently during postmortem aging depending on goose breed ( Okruszek et al., 2008 , Okruszek, 2012a , Tůmová and Uhliřová, 2013 ) and variety ( Boz et al., 2019 ).…”

“…In Poland, 14 breeds of these birds are currently raised. In recent years, interest in the use of native, noncommercial breeds of geese for meat production has increased ( Tilki et al., 2005 , Saatci et al., 2009 , Kapkowska et al., 2011 , Kirmizibayrak et al., 2011 , Tůmová and Uhliřová, 2013 , Uhliřová and Tůmová, 2014 , Uhliřová et al., 2018 , Uhliřová et al., 2019 , Boz et al., 2019 ). Moreover, traditional goose breeds can be used to produce crosses with increased meatiness and reduced carcass fat ( Isguzar and Pingel, 2003 ).…”

The aim of the study was to determine slaughter yield and meat quality of native Zatorska ( ZG ) goose and compare them to those of commercial hybrid White Koluda® goose ( WKG ) after fattening in an intensive production system. The experiment was carried out on 500 birds of each group and lasted up to 10 wk of age. The birds were kept on deep litter with access to free range and were fed with the same complete feed mixtures, according to dietary requirements for broiler geese. Body weight, carcass composition, and technological properties of breast and thigh muscles were evaluated (pH 24 , L*a*b* color, water holding capacity, thermal loss, drip loss, and shear force). In addition, chemical composition of breast and thigh muscles, fatty acid profile of muscle lipids, and amino acids of proteins were determined. The body weight, weight of eviscerated carcass, and dressing percentage of ZG were lower ( P < 0.05) than those in WKG. However, breast and thigh muscles of both groups of geese were characterized by similar technological and nutritive values. The differences in meat quality traits concerned only the shear force of breast muscles, with higher values ( P < 0.05) for WKG. Moreover, dry matter content in breast muscles of ZG was higher than that in WKG. The effect of goose genotype on the level of oleic acid and monounsaturated fatty acids in breast muscles was shown. Also, the amino acid proportion of meat protein depended on goose breed. Breast muscles of ZG were characterized by higher ( P < 0.05) content of some nonessential (Glu, Asp, Ala) and essential amino acids (Val, Thr), and thigh muscles contained less ( P < 0.05) Gly, Lys, and Leu and more Pro and Ile than WKG. The present results indicate that the meat of both ZG and WKG broilers showed good technological properties and basic chemical composition and fatty acid profile, and the protein was characterized by high nutritional value. Moreover, the smaller carcasses produced from ZG can better meet the needs of the current market.

“…However, information on the effects of age on fatty acids in goose muscle and adipose tissues is limited. Moreover, the effect of sex on the fatty acid content in muscle was studied in native Czech geese and crossbred Novohradska geese at 8 wk of age ( Uhlířová et al., 2019 ), but it has not been described in adult geese. Therefore, we conducted a research study to better understand the distribution of adipose tissue and the fatty acid composition of muscle and adipose tissues in geese, taking into account age and sex.…”

In this study, we evaluated the body fat distribution and fatty acid composition of muscles and adipose tissues of Yangzhou geese, including thirty 60-day-old goslings (15 males and 15 females) and 20 320-day-old geese (10 males and 10 females). Adipose tissues of Yangzhou geese were distributed widely and could be divided into 5 types: subcutaneous fat, abdominal fat, sartorial fat, neck fat, and mesenteric fat. Higher contents of abdominal fat, sartorial fat, neck fat, and mesenteric fat but a lower content of subcutaneous fat were found in adult geese than in goslings ( P ≤ 0.05). Adult female geese deposited more fat than adult male geese ( P ≤ 0.05). No difference was found in the fat distribution and fat content between male and female goslings ( P > 0.05). The breast muscle of adult geese was characterized by a higher content of total monounsaturated fatty acids ( ΣMUFAs ) and a lower content of n-6 polyunsaturated fatty acids ( ΣPUFAs n-6) than that of goslings ( P ≤ 0.05). Lower concentrations of total saturated fatty acids and ΣPUFA were found in adult female geese than in female goslings ( P ≤ 0.05). In comparison with adult female geese, the breast muscle of adult male geese had higher total saturated fatty acids and stearic acid ( P ≤ 0.05). For the thigh muscle, adult female geese had a higher ΣMUFAs content than adult male geese ( P ≤ 0.05). In adipose tissues, adult geese had a higher Σn-6/Σn-3 ratio but had lower contents of erucic acid, linolenic acid, arachidonic acid, docosatetraenoic acid, and ΣPUFA n-3 than goslings, and adult female geese had a higher ΣMUFAs content than adult male geese ( P ≤ 0.05). In conclusion, adult geese, especially adult female geese, accumulated more fat than goslings. Both age and sex affected the fatty acid composition of muscles and adipose tissues in geese. This research provides essential information not only for the nutritional evaluation of geese but also for the consumption and processing of goose products.

A number of goose breeds are raised commercially in China. However, the data on the slaughter performance of the goose breeds and the nutritional value of their meats lack a thorough comparative analysis. In this systematic review, the slaughter performance of the goose breeds and nutritional value of their meats were comparatively analyzed to provide an overview of the characteristics of the goose breeds raised commercially in China. Fifteen goose breeds were selected from 27 research articles published up to January 2022 on the slaughter performance of the goose breeds raised commercially in China and their nutrient composition after literature searching, literature screening, variety selection, and data collation. The slaughter indexes of the goose breeds and the basic nutrient composition, amino acid composition, and fatty acid composition of the meats of the goose breeds were standardized using min–max normalization and compared. The results suggest that the slaughter indexes and nutritional indicators of the meats of Yangzhou white goose, Xupu goose, Landaise geese, and Sichuan white goose are more balanced than those of the meats of the other goose breeds. The results of this review can lay the foundation for optimizing the breeding methods of the commercially raised goose breeds and processing methods of the meats of the geese. © 2022 Society of Chemical Industry.

Fatty acid composition of goose meat depending on genotype and sex

Abstract: NG had a relatively higher growth rate and meat oxidative stability, whereas the advantage of CG meat is its favourable fatty acid profile characterized by a higher PUFA content.
