Randaom growth data of body weights in Hinai chicken, which were sampled at 6, 10 and 21.4 weeks of ages obtained from 1984 to 1989, were applied to the Richards growth model by the three point method. Shape parameter“m”in the growth model was used from 0 to 2.0 with intervals of 0.1.
1) Adaptation of the coefficient R² (%) was obtained from the body weight data against the examination of 6 groups of models with 6, 10 and 21.4 weeks of growth stages before 6 weeks of age at 1977. The coefficient R² fromthe growth stages with 6, 10 and 21.4 weeks of age were presented at 95.96-98.33%, respectively. It was slightly lower than other data.
2) The parameter“A”which indicated the mature body weight from 1984 to 1989 was 1921.4-2524.9g in femal, respectively. The parameter“K”which indicated the growth rate was 0.0793-0.1758 in male and 0.0688-0.1258 in femal, respctively. Both of data from parameters“A”and“K”were not significant with growth rate against year.
3) Estimated data of body weight were quitly small at 0 weeks of age in both sexes. Shape parameter“m”was 0.5 as in the previous data which was estimated by the data included with 0 weeks of age. These results suggested that the growth pattern which was obtained from restricted data to age might be also estimated by the 3 point method.

Canonical discriminate analysis was applied to assessment of lactation stages with the standard data of metabolic profile test in Nagano Prefecture. The canonical discriminate coefficients for standard were calculated with 7 biochemical measurements from 176 dairy cow samples in 3 lactation stages. A theoretical accuracy of the coefficients was 81.25%. Similarly, shores induced from the coefficients were calculated with data of 215 dairy cows in 12 herds for field application. As results of comparison between standard and field application scores, improvement dairy herds were lower than other herds in error rate of the canonical discriminate analysis.

Eight blood biochemical data (Total Protein, Glucose, Total Cholesterol, Calcium, GOT, γ-GTP, ALP and LDH) were measured with 28 dairy cow serum samples by three kinds of biochemical, analytical equipments in the two Livestock Hygiene Service Centers in Kagawa Prefecture. The data were analysed statistically to compare with standard data of the control equipment (Fuji Dry Chem 5500V) in the Tobu Center. As results, Glu and LDH values were reveised with one regression equation, and TP and T-cho values also with two equations of same slopes for the standard values, respectively.
