Abstract

This study was conducted with the aim of comparing the value of the Dams Productivity Index (DPI) for weaning weight in Peranakan Ongole (PO) Cows in Wawasan and Purwodadi Dalam Villages, Tanjungsari District, South Lampung Regency. The study was conducted in November 2019 - January 2020 in Wawasan Village and Purwodadi Dalam Village, Tanjungsari District, South Lampung Regency, Lampung Province. The data used were secondary data taken from the recordings of 50 breeding cows from each village that have given birth twice. Survey method was used in this research with data sampling was done by using purposive sampling. Variables observed was date of birth, calf birth weight, calf weaning weight, weaning age, date of birth made at first parity and second parity. Result of this research showed that the Corrected Weaning Weights (CWW) in Wawasan Village (114.03 ± 10.87 kg) was higher (P <0.01) than those in Purwodadi Dalam Village (110.72 ± 10.55 kg). The average of DPI of PO cows in Wawasan Village (62.18 ± 15.57) was higher (P <0.01) than those in Purwodadi Dalam Village (51.25 ± 16.62). The top nine DPI of PO cows in Wawasan Village were B.004, C.012, B.031, C.002, C.007 and in Purwodadi Dalam Village were B.009, B.005, B.004, B.002, and B.001.

Abstract

The research was conducted with a record of the growth performance of Saburai goats from 2013 to 2015 in the Saburai goat seed source area, Sumberejo District, Tanggamus Regency, Lampung Province. The research objective was to determine the appropriate breeding system to improve the growth performance of the offspring. This goal is achieved through heritability (h2) and repeatability (r) of growth performance (weight and body size at birth, weaning, and age one year). The h2 value was estimated using the step-by-step retreat method, the repeatability (r) was estimated using the permission class method. The results showed that the h2 and r values ​​of growth performance at birth, weaning, and age of one year were medium-class respectively. The h2 value at birth (body weight (BW) 0.10, height (TB) 0.11, body length (PB) 0.13, chest circumference (LD) 0.12, hip height (TP) 0.14) ) and the values ​​at birth (BW 0.12, TB 0.16, PB 0.14, LD 0.14, TP 0.16) are the lowest. The h2 value at weaning age (BW 0.16, TB 0.15, PB 0.16, LD 0.17, TP 0.17) and the r-value at weaning age (BW 0.16, TB 0.15, PB 0 , 16, LD 0.17, TP 0.17) were higher at birth. The value of h2 for one year of age (BW 0.18, TB 0.17, PB 0.16, LD 0.18, TP 0.19) and one year age value (BW 0.21, TB 0.22, PB 0, 22, LD 0.21, TP 0.21) the highest. It is provided that individual selection on the growth performance of weaning age and one year of age is an appropriate breeding system to improve the growth performance of Saburai goats.
