Selection of Sumba Ongole (So) Cattle Based on Breeding Value and Performance Test

Abstract

Selection of livestock was purposed to increase productivity. A performance test was conducted using 25 males and 25 females of Sumba Ongole (SO) cattle. The performance test were conducted in three periods (2014, 2015 and 2016) for about 535 days. Descriptive statistics ws used to analyze data of body weight. Cattle with age between 300 to 600 days were used for evaluation. Result showed that heritability value of yearling weight (YW365) was 0.77+0.68 as a high category. The highest breeding value of YW365 were 66.05 kg (male) and 41.89 kg (female). The average of corrected final weight (CFW) weight were 172.55+34.22 kg (male) and 159.80+37.73 kg (female). The performance test in this study obtained six A class (1 bull and 5 cows) based on the standard minimum of body measurements for SO cattle.

Breeding value of sires based on offspring weaning weight as a recommendation for selecting Kebumen Ongole Grade cattle

“…The value of standard error (SE) which obtained in this study were lower than its heritability, its can indicate that the value of heritability was accurate. The heritability value of this research was lower than Sumba Ongole and Aceh cattle at 0.77± 0.68; 0.49±0.59 respectively (Said et al, 2016;Putra et al, 2014) and also higher than several research of Indonesian cattle such as Ongole-crossbreed and Bali at 0,24; 0.27±0,16; 0.09±0.15 and 0.33±0.09, respectively (Paputungan et al, 2015;Gunawan and Jakaria, 2011). Some research has also been done on Asturiana de los Valles cattle, Northeastern Thai Indigenous Cattle, Hanwoo, Friesian and Charolais cattle at 0.29; 0.27±0.06; 0.15; 0.13±0.09 and 0.36 ± 0.01 (Goyache et al, 2003;Intaratham et al, 2008;Park et al, 2001;Atil et al, 2005;El-Saied et al, 2006).…”

“…The highest BV of sires in this research was 49.76 kg (KJ.J608) with the ratio 231.45 %, it means that the BV value of it was 131.45 % higher than the average BV in population. Several previous studies showed the higher BV in SO, PO, and Nellore cattle were 66.05 kg, 45.96 and 20.75 kg respectively (Said et al, 2016;Paputungan et al, 2015;Rodriguez and Guerra, 2013). The sire breeding values based on the offsprings weaning weight can be used as one of the selection criteria for choosing the superior sire.…”

Association of growth hormone (GH) gene polymorphism with growth and carcass in Sumba Ongole (SO) cattle

“…According to Agung et al (2015), the SO cattle has excellent potential as beef cattle based on the ability to gain higher dressing percentage (>50%) compare with other local breeds cattle in Indonesia. Recently, Indonesian farmers can do the selection in the SO cattle based on the MPPA value, breeding value and also performance test (Said et al, 2016a;Said et al, 2016b) but it is need more genetic information to determine the population for the breeding program. However, the superior SO cattle can be generated through the breeding program with early detection system based on the genetic information using molecular technology.…”

Non-genetic factor and genetic parameter analysis for growth traits in Sumba Ongole (SO) cattle

“…There are a few information about SO cattle productivity in Indonesia. Previous studies reported that the average of dressing percentage in SO bull was 51.73 -52.40 kg (Paskah et al, 2016) and the average of body weight in SO bull at ± 2.5 years age was 353.86 -474.08 kg (Said et al, 2016a). Moreover, the birth weight of SO cattle reached of 23.86±5.68 kg (male) and 19.77±3.19 kg (female) as reported by Said et al (2016b).…”
