[Development of clinically relevant vital signs of goat lambs of different breeds between birth and 28th day of life post natum].

Unlabelled: Monitoring caprine neonates is of great importance to minimize losses of valuable offspring potential. In addition to experience and ethological knowledge, it requires clinically relevant basic values for vitality assessment. Therefore, the aim of the study was to register appropriate basic parameters in healthy caprine lambs.

Material And Methods: Included in the study were 46 healthy, vital born lambs from 28 dams of the breeds White German Edel goat (WGE, n=15), Boer goat (n=7); Toggenburg goat (n=6). The three groups of subjects included 26 WGE, 9 Boer goat and 11 Toggenburg goat lambs. From birth, they were under intensive veterinary control. Vital signs respiratory rate, heart rate, and rectal temperature were measured immediately p.n.; 3rd, 12th, 24th h p.n.; 2nd, 3rd, 5th, 7th, 9th, 14th, 21st, and 28th d p.n. Furthermore, crown-rump length (CRL), birth weight, and weight development until 28th d p.n. Statistical analysis of the data was performed using BMDP/Dynamic Release 7.0 and two-factorial analysis of variance.

Results: Vital signs showed a typical course in the first 4 weeks p.n. with a significant decrease in values from the 5th d. p.n. Time as well as breed had significant influence on the development of the respective profiles (covariance analysis; p<0.001). There was a linear correlation for SSL and birth weight (y=0.0037 ×28969; r value 0.7805). Daily weight gain was independent of race and diet type. In contrast, there was a significant dependence between birth type (singleton or multiple birth) and weight gain with p<0.01 and between birth weight and sex (p<0.05).

Conclusion: The presented typical, breed-dependent postnatal changes of vital parameters in goat lambs in the period 0-28 days p.n. allow a more specific differentiation between clinically healthy and abnormal individuals in herd management using the physiological value tables. The age-correlated weight gain serves as a further evaluation parameter.
