Evaluation performance reproduction on dairy cattle (Case study in sinarjaya dairy cattle cooperationABSTRACT. Aim of the identification of performance reproduction was to find out the successfully of reproduction management in the dairy cattle firm or farmers. Performance reproduction of dairy cattle include days open, calving interval, service per conception, first service postpartum and length of the pregnancy. All of that performance reproduction values was ideal value and close relation to the production and that values was difference between farmer and depend of management themselves. Sinar Jaya cooperation is one of dairy cattle cooperation, since 1977 with the population about 1554 dairy cattle’s in year 2006, has been opportunity to find out the performance reproduction of dairy cattle in that cooperation. Dairy cattle about 197 cattle’s was used as a sample of the treatment, which were minimum two times calving period with the completely recording of reproduction activity. The method of this research was descriptive method and the data was collected as a census method. As a conclusion, reproduction performance for the first service postpartum, days open and calving interval were ideal values but service per conception was bigger than optimal value.

The Relationship

The purpose of this research was to know the relationship between age with calving inteval (CI), days open (DO), and service per conception (S/C) in Friesian Holstein dairy cattle (FH). The research was started on Desember 2017 to January 2018 in PT. Greenfields Indonesia partnerships, KecamatanWagir Kabupaten Malang. The materials of the search used were 100 heads of dairy cattle which had at least two times of parturition. The method used in this research was a survey and data collection. The data were obtained from the records of reproduction. Data analysis was multiple linear regression using SPSS software 21.0 version. The results showed that the values of CI (434,9±58,9 days, 449,4±66,2 days, and 431,8±59,2 days), DO (218,9±58,7 days, 218,9±58,7 days, dan 217,6±54,1 days), dan S/C (3,2±1,8 times, 4,3±1,9 times, 2,6±1,1 times) for the ages of 4, 5, 6. The relationship between age with CI and DO were not significant (P>0,05), but the relationship between age with S/C was significant (P<0,05). The value of S/C increased on dairy cattle at age of 4 to 5 years and started to decreased at the age of 6 years.

In spite of the economic importance of fertility and increased knowledge of reproductive biology in the cow, efficiency of reproductive performance has continued to decline in dairy cattle. Improvements in fertility through genetic selection may be a possible approach to increase reproductive efficiency in dairy cattle. Although progress may be slow because of low heritabilities, ignoring fertility in genetic improvement programs has contributed to the current fertility problems. The objectives of this study were to (1) estimate genetic parameters and breeding values for fertility traits based on data from milk recording programs on a Holstein population and (2) develop a multi-trait selection index (dollar fertility value; $F) based on estimated breeding values. Data representing 3,282,843 lactations and 1,622,088 animals (cows and bulls from 1936 to 2007) were used for the analysis and obtained from official records maintained by the Argentinean Holstein Association (ACHA). Data were collected from official milk records, and lactations were standardized to 305 DIM for milk, protein, and fat. Gestation period was considered to be 282 days and restrictions were applied to ensure the quality of data (days open <40 and >350 days; calving interval <300 and >600 days; and contemporary groups with <25 lactations were eliminated). Days open (DO), calving interval (CI), age to first calving (AFC), and daughter pregnancy rate (DPR) were traits chosen for genetic parameter estimation. Daughter pregnancy rate was calculated from DO as PR = 0.25 × (233 DO); Kuhn et al. 2004 J. Dairy Sci. 87, 2277-2284. Animal models by lactation for each fertility trait included contemporary group (dairy herd and calving year), calving month, animal effect, milk production as a covariate and error term. Multiple-trait derivative-free restricted maximum likelihood (MTDFREML) was used to estimate covariance components (Boldman et al. 1995 ARS, USDA). Solutions for fixed effects, breeding values, and sampling variances (accuracies) were obtained for each trait. The proposed selection index ($F) included AFC and CI, with economic weights from -0.28 and -4.9 $/year per cow for AFC and CI, respectively (Gonzalez-Recio et al. 2004 J. Dairy Sci. 87, 3053-3061). Heritabilities for DO and DPR ranged from 2 to 7%; CI ranged from 3 to 8%; and AFC was 16%. Predicted transmitting ability values across different lactations ranged from -18.5 to 15.8 days, -23.15 to 16.0 days, -4.0 to 4.6%, and -120.3 to 76.2 days for DO, CI, DPR, and AFC, respectively. Values for $F ranged from -$89.16 to $147.12 in this Holstein population. Results indicate substantial variation in fertility traits, suggesting that genetic selection may be effective in improving declines in fertility. Asociacion Criadores Holando Argentino (ACHA).

The purpose of this research is to compare the efficiency of reproductive performance Friesian Holstein (FH) in various lactation periods. The material used in this research is obtained from the records of reproductive performance Friesian Holstein (FH) cattle from Australia and has been developed in PT. Greenfield Indonesia farm. Datas were using 473 heads dairy cattle these were 100 heads for each lactation period I up to IV and 73 heads for lactation period V. The variable measured were efficiency of reproductive include service per conception (S/C); days open (DO) and calving interval (CI). The datas were analyzed using Completely Randomize Design one-way analyzes of variance (one way lay out) and if the result showed differences, the research will be continued using Least Significant Difference (LSD). The results showed that the higher lactation period of dairy cattle the greater the S/C, DO and CI (P<0.01). In lactation period I and II earned S/C value 2.6±1.3 and 2.1±1.1 were lower than lactation period III, IV and V which earned value 3.7±2.0; 4.2±2.1 and 4.1±2.3. DO in lactation I and II as118.3±49.7 days and 97.6±35.1 days were lower than lactation period III, IV, and V is 153.5±65.8 days;  168.2±81.5 days and 59.2±74.7 days. The lower CI was in period lactation II 365.8±36.9 days compared with lactation period III, IV  and V as 393.8±54.5 days; 406.1±78.3 days and 401.3±65.1 days. Conclusion of this research was lactation period has an effect on the performance of FH dairy reproduction, the higher of lactation period would increase S/C, DO and CI. Keywords : Calving Interval, Days Open, Friesian Holstein Cattle, Lactation Period, Service Per Conception.

Reproductive and economic data were recorded before and one year after the installation of Herd Navigator™ in a dairy farm with AMS (Automatic Milking System) located in a mountain area of Northern Italy. Number of days open reduced from 166 to 103 days, number of days between the first and second insemination decreased from 45 to 28 days, and days for identifying an abortion were 80 % less, from 31 to 6 days. The preliminary results highlight the usefulness of the proactive herd management system installed for the reproduction management. A basic economic model is proposed to evaluate the potential economic benefits coming from the introduction of this technology. The model considers the benefits deriving from the reduction of reproduction problems and, consequently, of days open. Considering the effects related to the above mentioned aspects in a case study involving 60 dairy cows, a return on investment over 5 years has been calculated.
