    Effect of udder type on udder traits, milk yield and some physicochemical characteristics of milk in Awassi ewes
    (Hellenic Veterinary Medical Soc, 2022) Seker, I.; Koseman, A.; Kul, S.; Seker, P.; Kocyigit, S.
    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 Awassi ewes. For this purpose, 54 ewes of 3-4 years old were used.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 effects of different industrial sugars on royal jelly production
    (Hellenic Veterinary Medical Soc, 2022) Karlidag, S.; Koseman, A.; Akyol, A.; Yil, G.; Seker, I.; Uyumlu, A. B.; Erdogan, S.
    In this study, the larval acceptance rate and the royal jelly yield in honeybee (Apis mellifera L.) colonies supplemented with different industrial sugars at different locations were determined. For this purpose, feeding groups (1. Sucrose group, 2. Glucose group, 3. Bee feed syrup group, 4. Control group) and locations (1. Battalgazi, 2. Dogansehir) were formed. In queenless colonies that produce royal jelly, in order to sustain 5-15 day-old young feeder worker bees, two sealed frames with brood from support colonies were added. The royal jelly yield was harvested seven times. Based on the location, the feeding groups, and the location x feeding groups interaction, 12600 larvae were grafted, 9054 larvae were accepted, and the larval acceptance rate was determined as 71.86%. Based on the location, feeding groups and the location x feeding group interaction, the yield per cell was calculated as 213.15 +/- 11.53 mg/ cell, the yield per colony as 6.88 +/- 0.38 g/app., and the total yield per colony as 34.40 +/- 1.91 g/colony. In the study, no statistically significant difference was determined between feeding with sucrose, bee feed and the supplementary feeding with glucose. On the other hand, it was determined that the location where the royal jelly was produced affected both the larval acceptance and the royal jelly yield.
