“…In the current study, the weights of hens and cocks were statistically similar which contradicted the reports of Lukanov and Pavlova (2021), Assefa and Melesse (2018), Moula et al (2011) and Youssao et al (2010) in which males were rather heavier than females. The similarity in weights of male and female birds may be due to the slow growth rate of local chicken.…”

“…Similarly, the shanks of males being taller than those of females in Tolon district was in consonance with works by Assefa and Melesse (2018), Halima (2007) and Youssao et al (2010) even though the values in those earlier reports were generally higher. The superiority of males to females in morphological body measurements have been widely reported (Yakubu et al, 2009;Youssao et al, 2010;Moula et al, 2011;Assefa and Melesse, 2018;Lukanov and Pavlova, 2021). Nevertheless, the similarity in values recorded for chest circumference for male and female domestic chickens contradicts findings of Yakubu et al (2009) and Moula et al (2011) who observed significant differences in chest circumferences between male and female birds.…”

The knowledge of morphometric measurements is paramount in domestic chicken production and marketing practices hence this research was undertaken to determine the morphological characteristics of domestic chicken in the Tolon District of Ghana. Birds reared under the traditional scavenging system, were randomly selected in four (Nyankpala, Tolon, Woribogu and Dondo) communities. Live body weight (BW) and thirteen morphometric traits namely, body length (BDL), chest circumference (CC), thigh circumference (TC), drumstick length (DL), shank length (SL), wing length (WGL), neck length (NL), head width (HDW), hip width (HPW), comb length (CL), head length (HDL), wattle length (WAL) and beak length (BKL) were measured. The data was subjected to general linear model, correlation and path coefficient analyses. The results revealed that, domestic chickens were generally smaller in sizes. The average values recorded were 0.99kg, 18.98cm, 20.60cm, 7.78cm, 11.78cm, 8.05cm, 16.17cm, 12.15cm, 2.34cm, 7.57cm, 3.39cm, 2.28cm, 1.70cm and 2.60cm for BW, BDL, CC, TC, DL, SL, WGL, NL, HDW, HPW, CL, HDL, WAL and BKL respectively. Location of birds significantly (P< 0.05) affected morphometric traits (BDL, CC, TC, SL, WGL, NL, HDW, CL, HPW, and WAL) of birds. Similarly, sex of birds had significant (P<0.05) effects on BDL, DL, SL, WGL, NL, HDW, CL, HDL, WAL and BKL whereas age had no significant (P>0.05) influence on any morphometric traits. The presence of crest affected (P<0.05) the variations in DL, SL, WAL and BKL. Also, presence of spur affected the variations (P<0.05) in BW, DL, NL, CL, HDL, WAL and BKL whiles comb type had no significant (P>0.05) effects on any morphometric trait. Correlation coefficients were generally low, with the highest (0.513) recorded between TC and CC. The highest direct path coefficient was obtained from CC (0.237), followed by BDL (0.156) and WAL (0.153). The findings of this work will be useful in characterization studies and breeding program for local domestic chickens.

“…On the other hand, indigenous chicken breeds are preserved by private breeders without commercial interests (Weigend et al., 2014). Scientific morphological comparisons have recently been made to accurately differentiate between breeds that appear roughly visually similar (Lukanov & Pavlova, 2021). Major problems in the small populations of indigenous chicken breeds include a rapid increase in inbreeding (Malomane et al., 2019), a lack of systematic performance testing and the absence of controlled breeding management (BLE, 2017).…”

Background/introduction In the absence of evidence‐based findings for Saxonian Chicken (SaChi) and German Langshan bantam (GLB), which are indigenous endangered German fancy chicken breeds, the objective of the present study was to characterise their growth performance and meat potential in an extensive free‐range system Methods A total of 340 hatching eggs from SaChi and 439 eggs from GLB were provided by private breeders, from which 263 SaChi (77.3%) and 174 GLB (39.6%) hatched (p < 0.001) Results By week 20, SaChi reached body weights of 2362.3 ± 315.3 g (mean ± SD; roosters) and 1624.7 ± 158.9 g (hens), while GLB weighed 1089.7 ± 148.3 g (roosters) and 820.4 ± 89.5 g (hens). Fitting the non‐linear regression of growth data to the Gompertz function estimated asymptotic body weights of 3131.4, 2363.9, 1359.2 and 1107.3 g, with inflection point times of 10.5, 10.3, 9.2 and 9.3 weeks in male SaChi, female SaChi, male GLB and female GLB, respectively. Moderate plumage damage was observed on days 18, 35, 53, 70 and 105 in SaChi and on days 53, 70 and 105 in GLB, while all birds presented completely intact plumage on day 140. Using a binary logistic regression model, breed, age and sex were shown to affect the plumage condition (p < 0.001 each). Roosters were slaughtered in week 20. No breed effects were detected in the carcass yield (SaChi: 68.8 ± 1.7%, GLB: 69.7 ± 1.8%) (p = 0.135) or abdominal fat share (SaChi: 0.89 ± 0.15%, GLB: 1.08 ± 0.14%) (p = 0.281). The percentage of valuable cuts (breast fillets and legs) in the carcass was 43.8 ± 1.9% for SaChi and 43.1 ± 3.0% for GLB (p = 0.490) Discussion/conclusions In conclusion, this study provides insights into the performance traits and welfare indicators during the rearing of two endangered German chicken breeds.

Abstract. Ispenc and the Southwestern Bulgarian dzhinka are two small chicken breeds, originating respectively from two neighboring countries – Turkey and Bulgaria. They are characterized by uniformity in some major mutational exterior traits, such as beard and muffs, shank-feathering, vulture hocks, and rose comb. The aim of the study was to compare some of the main morphological and morphometric features of the Ispenc and Southwestern Bulgarian dzhinka breeds. The study was performed on 15 roosters and 25 hens of each breed. Ispenc had a significantly higher live body weight, respectively by 19.65% in roosters and by 17.11% in hens, compared to the Southwestern Bulgarian dzhinka (p<0.001). The birds of the Turkish breed are polydactyl, 5-toed, while the Bulgarian breed does not have this mutation. The length of the back, the wingspan and the length of the shank in Ispenc were significantly higher in both sexes, compared to the Southwestern Bulgarian dzhinka (p<0.01). The comb of the Bulgarian breed is more compact, with significantly lower values in terms of its width (p<0.001). In terms of the dimensions of the head and its formations, there are more statistically significant differences between hens of the two breeds than between roosters. The study leads to the conclusion that the seemingly close breeds involved in the study show a number of statistically significant phenotypic differences, which suggests differences in their genotype.
