An experiment has been carried-out on physiological responses in Saanen, Anglo Nubian and Toggenburg goats at different body weights and feed intakes during treadmill exercise at $30{^{\circ}C}$ environmental temperature (ET). The results showed that respiration rate (RR) was significant between time ${\times}$ breed interaction (p < 0.01), with values for the Anglo Nubian being least, while the Saanen was intermediate. With time, RR differed significantly, and after 1 h the respective RR were 238, 221 and 303/min in the Saanen, Anglo Nubian and Toggenburg. With time the rectal temperature (Tr) increased gradually and after 1 h exercise mean values were 40.8, 41.3 and $40.7{^{\circ}C}$ in the Saanen, Anglo Nubian and Toggenburg respectively. Rump skin temperature (RTs) values differed significantly between Anglo Nubians and Toggenburgs, with the differences averaging 0.3, 0.6, 0.4 and $0.4{^{\circ}C}$ after 15, 30, 45 and 60 min exercise respectively. With breed, highest loin skin temperature (LTs) values were in the Anglo Nubian, with an overall mean of $37.9{^{\circ}C}$ (p < 0.05).

The objective of the present study was to investigate the accuracy of mastitis diagnostic indicators for different dairy goat breeds. Biweekly milk samples were collected from individual half mammary gland of seven Saanen and seven Alpine dairy goats in the period of 40 to 120 days in milk. With threshold value set at 2.8 and 3.1 for Alpine and Saanen dairy goats, respectively, log (SPC) offered good sensitivity (0.89, 0.93), specificity (0.88, 0.95), positive predictive value (0.75, 0.85) and negative predictive value (0.95, 0.98) as a mastitis diagnostic tool. The correlations of log (SPC) with milk yield, log (SCC), ALP, LDH, $Na^{+}$, $K^{+}$ and EC were significant in Saanen dairy goats (p<0.05), with the highest correlation coefficient (0.653) existing between log (SPC) and log (SCC). The correlations of log (SPC) with milk yield, milk fat, milk protein, log (SCC), $Na^{+}$, $K^{+}$, EC were significant in Alpine dairy goats (p<0.05), with the highest correlation coefficient (0.416) existing between log (SPC) and log (SCC). There were different best-fit regression equations with different multiple diagnostic indicators for Saanen and Alpine dairy goats. In conclusion, different breeds of dairy goats may have to adapt different mastitis diagnostic parameters for a better diagnosis.

We report herein the successful results of estrus induction, sperm cryopreservation and kids born by transcervical insemination of frozen-thawed semen in a Saanen goat. Flugestone acetate (FGA: 60 mg) was inserted into vagina for 15 days. The goat was intramuscularly injected with 400 IU PMSG and 200 IU hCG ($PG600^{(R)}$: Intervet, Korea) a day before withdrawal of the FGA sponge. Follicles and corpora lutea were identified on both ovaries by laparoscopy. Artificial insemination was performed 46 hours after removal of FGA sponge. The concentration of frozen-thawed semen was $3.975{\times}10^8/ml$ and 0.5 ml of frozen-thawed semen was transcervically inseminated into uterine body under anesthesia. Three kids, all females, were born 144 days after artificial insemination. This is the first report producing kids by transcervical insemination of frozen-thawed semen in a Saanen goat of which the estrus was induced by FGA sponges, PMSG and hCG during non-breeding season in Korea.

This trial evaluated the effects of dietary supplementation with monensin sodium on dry matter intake, metabolic parameters and milk yield and milk composition of dairy Saanen goats in the periparturient period. Twelve Saanen pregnant dairy goats were assigned to a treatment and a control group. Saanen goats were fed monensin as its 10% sodium salt in the amount of 33 mg/kg of total dry matter intake during 30 d before parturition till d 42 in milk. Blood samples were collected from each goat at d 30, 15 and 7 before expected kidding time and also in d 1, 7, 13, 19, 21, 28, 35 and 42 postpartum. The serum concentrations of ${\beta}$-Hydroxybutyrate (BHBA), non-esterifed fatty acid (NEFA), calcium, magnesium, inorganic phosphorus, cholesterol, triglyceride, urea, total protein, albumin and glucose and aspartate aminotransferase (AST) activity were determined. The BHBA concentration significantly decreased in goats, which received monensin in comparison to controls in the postpartum period (p = 0.049). The concentration of sodium (Na) was significantly influenced by monensin treatment in the postpartum period (p = 0.048). In addition, the difference in dry matter intake was highly significant between the two groups during the pre-partum period. Controls had more dry matter intake (DMI) than treatment goats (p = 0.0001). Mean 3.5% fat corrected milk production was not influenced by monensin treatment. However, milk fat percentage was significantly decreased in monensin treated goats (p = 0.0017).

Caseous lymphadenitis (CLA) is a chronic and contagious disease of sheep and goats caused by Corynebacterium (C.) pseudotuberculosis. A four-year-old female Saanen dairy goat was submitted to the Animal Disease Diagnostic Center at National Veterinary Research and Quarantine Service. The clinical signs of the goat were emaciation, abortion and quadriplegia. The multifocal nodules of lymph nodes were encapsulated and filled with whitish caseous contents on the cut surface. Histopathologically, lymph nodes displayed suppurative and necrotizing granulomas. Caseous necrosis was diffusely observed in the center of the lymph nodes. Gram positive bacilli were shown in the lesions. C. pseudotuberculosis was isolated and confirmed by the biochemical tests and PCR assay. Based on clinical signs, histopathological examination and bacterial isolation, we diagnosed this case as CLA. To our knowledge, this is the first report of CLA in a Saanen dairy goat in Korea.
