“…Udder morphology is therefore related to milk production traits in dairy species and has received particular attention in ruminants (Akdag et al 2017;Vrdoljak et al 2020;Tuliozi et al 2021), lesser for donkeys (D'alessandro et al 2015).…”

To date, no selective actions have been taken to improve milk traits in dairy donkeys, and the characteristics of the udder are not well defined in relation to the productive characteristics. This study aimed at increasing knowledge on Amiata dairy donkey body conformation, udder traits, and their relationship with milk yield and quality. Morphological, udder, and teat measurements and milk evaluations of 45 pluriparous jennies were carried out. The average wither height of the jennies was 126 cm and the chest girth was 148 cm; a large standard deviation of some body measurements was found. Forty-nine percent of the animals showed a moderately developed udder, while most of the jennies had symmetrical half-udders (96%) and the intermammary cleft was clearly visible in 53% of subjects. Correlation analysis indicated that bigger animals tend to have bigger udders, higher teat diameter, and greater distance between teat tips. A positive correlation between the teat length and the milk fat was found ( p < 0.01), which suggests that jennies with longer teats have a better ability to release milk fat. The results of this paper may be useful to define the characteristics of the milking device and address selective choices of the animals.

“…The distribution of milk in the udder also affects the milk composition. In dairy ruminants, correlations have been found between udder size and the content of some milk constituents (Akdag et al 2017;Vrdoljak et al 2020).…”

“…In some studies, it has been reported that the udder size and volume can be used as a useful tool for estimating milk yield in sheep. Because, there are high positive correlations between many of these characteristics and the lactation milk yield, lactation period, and the daily average milk yield (Seker et al, 2004;Merkhan, 2014;AL-Khazrajiand AL-Khuzai, 2017;Kaygısız and Dağ, 2017;Akdag et al, 2018;Arcos-Álvarez et al, 2020;Özyürek, 2020).…”

In this study, it was aimed to determine the effects of udder type on milk yield, udder and teat traits, and some physicochemical properties of milk in 54 Awassi ewe aged 3-4 years. In this study, Type-3 udder, which was reported to be prevalent in breeded Awassi ewes. Type-4, Type-5, and Type-6 udders were not detected in ewes. The lactation period, lactation, and the daily average milk yield values were calculated as 208.33 days, 138.59 liters, and 659.49 ml, respectively. The 90th day of lactation measurements were as follows: udder circumference (44.58 ± 0.51 cm), udder width (13.20 ± 0.36 cm), udder depth (17.66 ± 0.58 cm), udder volume (881.25 ± 37.41 ml), teat length-right (3.84 ± 0.15 cm), teat length-left (3.64 ± 0.17 cm), teat diameter-right (2.07 ± 0.14 cm). The values of the physicochemical characteristics of milk generally showed an increase from the beginning to the middle periods of lactation and then decreased. In conclusion, udder type had no significant effect on the lactation period, milk yield, udder and teat characteristics and the physicochemical properties of milk in Awassi ewes. New studies are required in the determination of the yield and other characteristics of ewes in Turkey.

The objective of this study was to uncover the milk composition traits of Norduz sheep, which are bred in the Gürpınar district of the Van province, during the mid-term lactation period. The chosen ewes exhibited no signs of clinical or subclinical mastitis. A total of 104 sheep milk samples were meticulously collected to undergo comprehensive milk composition analysis. The chemical and physical attributes of Norduz sheep milk were methodically determined utilizing a milk autoanalyzer. The mean values for various milk constituents were as follows: milk fat (%), 2.48±0.11; solids-not-fat (SNF) (%), 10.76±0.08; milk protein (%), 5.09±0.04; lactose (%), 4.79±0.04; pH, 6.93±0.02; conductivity (mS/cm), 4.41±0.04; freezing point (֯C), -0.602±0.80; salt (%), 0.8035±0.66; and density (kg/m3), 1039.73±0.39. Noteworthy negative and statistically significant correlations were observed between milk fat and protein (r=-0.36, p
