Udder morphology and milk yield of Tsigai sheep
Original language description
This study aimed to determine how udder structure and milkability in Tsigai and crossbred Tsigai x Lacaune dairy sheep are impacted by breed and the progression of lactations. The measurements were analysed from 382 to 391 ewes during their first through third lactations, taken at two milk testing periods in varying stages of lactation. Udder morphology was evaluated through linear dimensions and ultrasound imaging, capturing elements such as udder depth, teat placement, cisternal proportions, and attachment quality. Milk yield dynamics were examined using flow meters that recorded milk letdown every 10 seconds to determine machine milk yield, machine-stripped milk, and total milk yield. The results revealed significant variances in udder size and cisternal depth between breeds, with crossbred ewes having larger udders and higher milk yields than pure Tsigai ewes. Furthermore, udder morphology deteriorated as lactation order increased, with teats becoming more horizontal and teat length expanding. Cisternal depth displayed the greatest variability among linear traits, correlating with differences in milking efficiency. Statistical tests confirmed that older ewes had more ample cisterns, thereby supporting the hypothesis that parity influences udder conformation and milkability. In conclusion, these findings provide insight into the breed-specific and lactation-related factors affecting milk production, underlining the importance of udder structure traits for optimizing dairy sheep selection and management strategies.
