“…In the current study, the calculated fat was found to be lower but the lactose was higher than the values reported by Şeker et al [8], Kahraman and Yüceer Özkul [15], Panayotov et al [18], Çelik and Özdemir [23] and also Tarazona et al [24]. Protein was found to be lower than the values reported by Kahraman and Yüceer Özkul [15], Panayotov et al [18], Çelik and Özdemir [23] and also Tarazona et al [24] but rate was to be higher than the value reported by Şeker et al [8].…”

“…The lactation periods of ewes were calculated according to Berger and Thomas [7]. Fat (%), solid non-fat (%), density (g•ml -1 ), lactose (%), mineral (%), protein (%), conductivity (mS•cm -1 ), and freezing point (°C) analyses of milk were measured by analyzer (Lactoscan MCCWS 3080, Milkotronic LTD, Bulgaria) in the morning and evening milking on the 30th day of lactation [8]. Measurements of the udder and teat before morning milking on the 30th day of lactation were made according to De La Fuente and Türkyılmaz [9] (FIG.…”

“…In another study conducted on Awassi sheep, the fat was 6.06 ± 0.21%, the protein was 3.77 ± 0.05%, the lactose was 5.73 ± 0.07%, the dry matter was 10.66 ± 0.13%, the mineral was 0.79 ± 0.01%. In addition, it was calculated that density was 1.035 ± 0.00 g•mL -1 , freezing point -0.75 ± 0.02°C, and conductivity 5.04 ± 0.02 ms•cm -1 [8]. In addition, protein, fat, lactose, and solid non-fat were found at 5.20-5.30, 5.70-6.10, 4.90-5.30, and 11.00-11.40%, in Awassi ewes, respectively [23].…”

It was aimed to determine the effects of udder type on udder traits, milk yield and some physicochemical properties of Bafra (Chios × Karayaka) ewes. The lactation length, daily milk yield, lactation milk yield, and daily average milk yield of ewes were determined. In addition the udder type were determined, udder and teat traits were measured. The fat, solid non–fat, protein, lactose, mineral, density, freezing point, and conductivity values of the milk were determined. Type 3 udder was observed at the highest rate (37.5%) and Type 5 udders were not detected in ewes. The lactation length, daily, and lactation milk yield values were calculated as 177.75 days, 868.60 g and 156.86 kg, respectively. Udder circumference, udder width, udder depth, right teat length, left teat length, right teat diameter, left teat diameter, the distance between teats and udder floor height from the ground was calculated as 40.95 ± 0.63, 12.36 ± 0.30, 16.24 ± 0.40, 2.85 ± 0.09, 2.76 ± 0.09, 1.49 ± 0.03, 1.43 ± 0.04, 15.35 ± 0.23, and 31.88 ± 0.70 cm, respectively. Rates of fat, protein, lactose, solid non–fat, mineral and also density, freezing point, and conductivity were calculated at 5.17 ± 0.30, 1039.08 ± 0.31, 6.24 ± 0.05, 11.51 ± 0.10, 0.88 ± 0.009, 1039.08 ± 0.31 g·mL-1, -0.80 ± 0.009°C and 5.26 ± 0.03 mS·cm-1, respectively. It has been determined that Bafra sheep can be a suitable breed for breeding in the conditions of Malatya, Province of Turkey. However, more scientific research should be done on this topic and the level of milk production should be improved.

“…Many studies have been conducted on the Awassi breed examining the udder and teat characteristics and the relationships between them and the milk yield in particular [1,2,7,11,12,13,14,15]. However, similar studies on Bafra sheep [9,16] are observed to be insufficient and not widespread.…”

This study was carried in order to evaluate the linear morphological characteristics of the udder and teats in the breeder conditions of Awassi and Bafra (Chios × Karayaka) ewes (Ovis aries) and to determine the udder types, lactation milk yield and the lactation period of the ewes. One hundred two Awassi and 61 Bafra ewes were included in the study. The means of the linear scores of udder depth, udder furrow, udder attachment, teat shape, teat angle and teat placement in Awassi ewes were determined as 6.10 ± 0.27, 6.33 ± 0.27, 4.49 ± 0.27, 6.49 ± 0.33, 3.98 ± 0.29, and 1.47 ± 0.14, respectively. The same parameters were determined as 6.31 ± 0.28, 6.77 ± 0.32, 5.72 ± 0.24, 1.20 ± 0.11, 1.72 ± 0.26, and 1.20 ± 0.11, respectively, in Bafra ewes. Significant differences were found between Awassi and Bafra breeds in terms of udder types (P<0.01). The type 3 udder, suitable for milking, was determined at the highest rate in both breeds, but type 2 udder was not detected in Awassi ewes. Statistically significant differences were found between Awassi and Bafra ewes in terms of linear morphological characteristics of udder and teat, udder attachment, teat shape, teat angle and 60th day milk yield, daily average milk yield and lactation period (P<0.01). Lactation milk yield and lactation period were calculated as 139.85 ± 5.31 kg and 208.53 ± 4.471 days, respectively, in Awassi ewes and 145.91 ± 9.97 kg and 175.23 ± 4.635 days in Bafra ewes, respectively. As a result, in order for linear udder characteristics to be used safely as an indirect selection criterion, there is a need for studies with a higher number of ewes and to calculate the repeatability and heritability.

“…In order to improve udder morphology and milkability, it is recommended to use linear udder traits in practice. The relationship of udder traits with milk yield in sheep has been investigated in many studies (Dzidic et al, 2004;Kominakis et al, 2009;Mioč et al, 2009;Prpic et al, 2013;Vrdoljak et al, 2020;Seker et al, 2022;Tolu and Yazgan, 2022;Marshall et al, 2023;Smith et al, 2023). Kaygisiz and Dag (2017) found generally positive and significant correlations between udder size and type of udder and milk yield.…”

Linear scores and measures of both udder and teat shape and size (thirteen traits) were assessed in 83 ewes of Improved Valachian breed (IV) and in crossbreds with East Friesian breed (EF 25% or EF 50%). At the same time, cistern measures and cross-section areas (fourteen traits) as well as milk yield and milkability were scanned using ultrasound technique or measured in the same individuals (130 measurements in each trait). Crossbreds with EF 50% had the largest udders in terms of depth, width, and height, as determined by either a nine-point linear score or exact measurements. Additionally, these crossbreds had teats that were more horizontally placed and the most appropriate udder attachment and shape. more horizontally and most appropriate udder attachment and shape. Ultrasound scans revealed that the areas of both the left and right udder cisterns scanned by ultrasound were the highest in EF 50% crosses. Overall cistern cross-section areas scanned from the side were 2934.6 mm2 in IV, 2932.6 mm2 in crosses of EF 25% and 3559.4 mm2 in crosses of EF 50% (P<0.05). Crossbreds of EF 50% had more appropriate machine milked milk and total milk yield (311.1 and 424.7 ml) than purebred IV (231.8 and 336.1 ml; P>0.05). On average, the proportion of machine-stripped milk was 33.2%, and non-significant influence of genotype was shown. Furthermore, all traits under study showed non significant differences between crosses of EF 25% and 50%.
