Function Analysis of Milk Yield on Small Holder Dairy Cattle in Sumbang Banyumas Region

A survey on smallholder dairy cow had conducted in Banyumas region from November 8th 1999 up to February 8th 2000. Forty six respondents were involved in this study (as samples). Cobb - Douglas analysis was applied in this survey. From the study can be concluded that a small holder owned 3.02 heads of dairy cow (2.2  ST), 1.44 heads of lactating cow with 9.77 L/day milk production on average. The benefit of the backyard farming was RP.70.603,225 per month on average. Feeding was the biggest influence on benefit because feed cost was 65.81 percent from the production cost. The milk production function , by the equation: Y = 0,8958 X1⁰·⁰³³² X2 0.049 X30.168 X40.608 The four variables can explain 92.4 percent (R²=0,924)on the milk  production variation .It can be suggested that to improve milk production on dairy cows can be done by intensifying labour, and improving the forage feeding.

Correlation between Floor Space and Sanitation of Cage with Mastitis Disease Occurrence on The Dairy C

The objective of research was to know the correlation between floor space and sanitation of cage with mastitis disease occurance on the dairy cattle. Sixtiy infected mastitis disease dairy cows were used in the research in the Banyumas regency. Survey was applied in this experiment and Linier Multiple Regression was used. The result showed that there were correlations between floor space  and sanitation of cage with mastitis which follow the regression line Yi = 15,355 + 1,087 X1 – 0,249 X2 (Animal Production 2(1): 9-12Key Words: mastitis, floor space, and sanitation

Study on Estimation of Milk Production Based on Heart Girth Measurement and Udder Size of Fries Holland Dairy Cows

An experiment entitled “Study on Estimation of Milk Production Based on Heart Girth Measurement and Udder Size of Fries Holland Dairy Cows “ has been carried at Karanglewas District Banyumas Regency. The objectives of this experiment were (1) to predict milk production of Fries Holland cows based on measurement of heart girth and udder size; (2) to complete information in attempting milk production estimation, especially Fries Holland cows; (3) to help the publics in case of productive cows selection. The material of this experiment was 40 heads of Fries Holland cows, at age of 3 years up to 5 years old. The result of this experiment (after the milk product data were corrected into 305 days lactation), showes that the average of heart girth was 180.20 ± 7.06 cm; udder size was 89.03 ± 23.35 dm2 and milk production was 2326.54 ± 331.79 litters. The data analysis indicated that correlation coefisient r = 0.87 and determination coefisient (R2) = 0,7651 and the multiple regression equation : Y = 1465.66 + 1.42 X1+ 6.79 X2. From the result of this experiment, if could be conclude that udder size parameter was the best variable of milk production estimation compared to heart girth and if can be used to estimated milk production.
