Abstract
An experiment was designed to study the growth phenotypes of piglets born to sows injected withpregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) prior to mating inorder to improve endogenous secretions of pregnant hormones during pregnancy. The experimental sowsused in this study were 10 local breed sows with body weight ranges of 30-40 kg. Before mating, estrouscycles of the experimental sows were synchronized by injecting 3.75 mg prostaglandin twice with 14 daysinterval. The experimental sows were then divided into two groups, each consisted of 5 sows. The firstgroup was injected with 200 IU PMSG and 100 IU hCG per sow at the same time with the secondprostaglandin injection (day 15th), while the second group was not injected with PMSG and hCG but it wasinjected with NaCl 0.95% as a control. After showing estrous behavior, the experimental sows were mixedwith selected boars for natural mating. The pregnant sows were maintained until farrowing and weaning. Variable measured were body weights and body lengths and leg heights of the piglets at birth andweaning. The results showed that injection of the sows with PMSG and hCG prior to the mating, increasedbirth weight by 76.92% and total birth weight of live piglets per sow by 265.6% as compared to control.Piglets born to sows injected with PMSG and hCG prior to mating had higher survival rate with adramatically decreased mortality and a higher pre-weaning growth rate that finally increased total weightof weaned pigs per sows dramatically by 107.44% (increased 2 times) as compared to control. It is concludedthat the growth phenotypes of local piglets could be improved by injecting the sows with gonadotropinbefore mating.

Summary
Variable measured were body weights and body lengths and leg heights of the piglets at birth and weaning. Teknologi tersebut telah terbukti meningkatkan sekresi endogen hormon kebuntingan dan memperbaiki lingkungan uterus dan plasenta selama periode kebuntingan, sehingga memperbaiki pertumbuhan embrio dan fetus (Manalu et al, 1998; Adriani et al, 2007; Mege et al, 2007) yang akhirnya memperbaiki bobot lahir anak (Manalu et al, 2000b; Mege et al, 2006; Adriani et al, 2007; Lapian et al, 2013). Peningkatan sekresi endogen hormon kebuntingan terbukti memperbaiki pertumbuhan dan perkembangan kelenjar susu sehingga meningkatkan produksi susu pada masa laktasi (Manalu et al, 2000a; Sudjatmogo et al, 2001; Adriani et al, 2004; Lapian et al, 2013) yang akhirnya memperbaiki pertumbuhan anak prasapih dan pascasapih (Andriyanto dan Manalu, 2011; Lapian et al, 2013). Perbaikan pertumbuhan prenatal dengan perbaikan sekresi endogen hormon kebuntingan selama periode kebuntingan, menghasilkan anak yang unggul dengan memiliki daya tahan hidup, laju pertumbuhan prasapih, dan pascasapih yang lebih baik sehingga meningkatkan produktivitas induk
