Abstract

The objectives of this research were to estimate the genetic parameters of production characteristics, breeding value (BV), weaning weight ratio (WWR) correlation with BV and most probable producing ability (MPPA) of Simmental cattle reared at Balai Pembibitan Ternak Unggul Sapi Potong Padang Mengatas. Research was based on records of birth weight (BW), weaning weight (WW), post weaning average daily gain (ADG) and yearling weight (YW) from 2002 to 2007. Heritability value (h2) was estimated for BV, WW, ADG and YW using paternal-half sib correlation and repeatability value (r) of characteristics of both using intra class correlation. The genetic correlation (rG) of BW-WW, WW-YW, WW-ADG, WW-YW, WW-ADG and YW-ADG were analyzed by variance and covariance. BV and MPPA estimation was base on record of weaning weight. The h2 value of BW, WW, YW and ADG were 0.11±0.09; 0.39±0.16; 0.43±0.19; and 0.46±0.20, respectively. The r of BW, WW, YW and ADG, were 0.25±0.16; 0.32±0.18; 0.25±0.22; and 0.34±0.16, respectively. The genetic correlation value of BW-WW, WW-YW, WW-ADG, WW-YW, WW-ADG and YW-ADG were 0.29±0.37; 0.46±0.33; 0.2 ±0.39; 0.68±0.16; 0.006±0.30 and 0.57±0.21, respectively. From 18 Bulls, 10 bulls (55.56%) had the BV higher then average population value, 142.21 kg and the remaining 8 bulls (44.44%) was lower then average population value. Frequency of the BV of prospective male and female with WW higher than WW average was 210 calves (44.68%); whereas, 260 calves (55.32%) had WW lower than average population corrected with parent age (130.21 kg). Range of absolute BV was from 112.77 kg to 155.91 kg. The BV of male had average frequency higher than that of female, i.e. 149 males (66.22%) compared to 61 female (24.90%). The MPPA with above the average WW of the population was 150 cows (41.67%) and the rest of cows (210 head or 58.33%) were under theaverage. The WWR had positive and significant correlation (1.00**) with the NP. It means that, if the cattle have a high WWR, they will also have a high NP, so that they can be used as the criteria of selection.(Key words: Simmental cattle, Genetic parameters, Breeding value, Most probable producing ability, Weaning weight ratio)

Abstract

The objective of this study was to estimate potential genetic of Friesian Holstein at Taurus Dairy Farm, Cicurug, Sukabumi. Data observed were secondary data of milk yield, calving interval, service per conception, age at first calving, and length of lactation records of cows that have been experiencing one or more lactation since year 2003 to 2009, then were standardized based on milk yield by using correction factor 305 days of lactation period and mature equivalent (ME). Production trait (milk yield), reproduction traits (CI, S/C, length of lactation, and age at first calving) were analyzed by descriptive statistic. Data were analyzed by paternal half-sib correlation and nested method to get heritability, while the repeatability value were obtained by interclass and intraclass correlation method. Heritability and repeatability value then was used to count most probable producing ability (MPPA) and estimated real producing ability value and estimated transmitting ability (ETA) and breeding value (NP) of dairy cows. Estimates of heritability of milk yield by using nested are 0.287±0.135 (h2s), 0.310±0.154 (h2d), and 0.299±0.103 (h2(d+s)), and paternal half-sib correlation method was 0.63±0.23. Estimates of CI heritability with paternal half-sib method was 0.46±0.23, and values obtained using nested were 0.038±0.106 (h2s), 0.733±0.231 (h2d), 0.385±0.117 (h2(d+s)). Estimated heritability of S/Cwith paternal half-sib method was 0.001±0.110 and using nested method are -0.022±0.043 (h2s), 0.098±0.133 (h2d), 0.038±0.072 (h2(d+s)). Estimated value of milk yield repeatability with interclass correlation was 0.43±0.1 and intraclass correlation was 0.15±0.05. CI repeatability value with interclass correlation method was 0.00±0.09 and intraclass correlation was 0.19±0.07. S/C repeatability value with interclass correlation method was 0.12±0.15 and intraclass correlation was 0.02±0.05. Based on the calculation, the highest five ranks on the estimated relative value of MPPA and ERPA from 147 holstein friesian dairy cows with interclass repeatability method and 279 Friesian Holsteindairycows with intraclass method were 1966, 1941, 2180, 2087, and 2248. Database, Kimball, Beam, Doeboy, Paul, Varlour and Cassela get the highest rank, based on the estimated value of ETA and NP for 40 bulls using paternal half-sib heritability method and 38 bulls using nested heritability method.(Keywords: Friesian Holstein dairy cows, Milk yield, Reproduction traits, Genetic parameter)
