Judul: Predection of Litter Size, Lamb Birth Weight, Mammary Gland Growth Indices and Milk Yield in Relation to Weaning Weight Based on Hormonal and Blood Metabolite Profiles During Pregnancy in Sheep (Ovis aries)
Abstrak: Forty five Javanese Thin-tail ewes (20, 19, and 6 ewes carrying 1, 2-3, and 0 fetuses, respectively) were used to measure hormonal (progesterone, est radial, three iodothyronine [T3], cort is01 ) and metabolite (beta-hydroxy butyric acid [BHBA], blood urea nitrogen [BUN]) profiles during pregnancy to predict litter size, lamb birth weight, mammary gland growth and development, milk production, mammary gland involution, and lamb weaning weight. Eighteen ewes (9, 6, and 3 ewes carrying 1, 2-3, and 0 fetuses, respectively) were sacrificed at parturition to determine mammary gland growth at the beginning of lactation. The others (11, 13, and 3 ewes carrying 1, 2-3, and 0 fetuses, respectively) were maintained during lactation and supplemented with 500 or 1000 g concent rate per ewes daily, t o determine milk product ion and mammary gland involution. Ewes with higher litter size had higher maternal serum progesterone, est radiol, T3, cortis0l, BHBA, and BUN during pregnancy. Ewes with higher litter size had higher increase in maternal serum progesterone and estradiol concentrations during the second half of pregnancy until 4 months of gestation age. Ewes with higher maternal serum progesterone and estradiol concent rations during the second half of pregnancy had heavier lambs at parturition.

Judul: Production performance of prolific Javanese sheep
Abstrak: The production performance of 425 Javanese ewes based on 1143 records produced at the Cicadas sheep Research Station of the Research Institute of Animal Production, Bogor, Indonesia, was evaluated in this study. Although the focus was on the effect of prolificacy and some major environmental causes of variation on lamb survival and ewe output at weaning, the analysis included other traits such as litter size, age at first lambing and lambing interval. Results concerning variation of litter size were consistent with previous studies and with a major gene hypothesis proposed to explain the genetic variation of the trait. Three lines of prolificacy classified as noncarriers or low line (LL) and carriers of the gene: medium (ML) and high line (HL) averaged 1.24, 1.81 and 2.26 lambs, respectively. from Ewes different prolificacy lines performed distinctly in different years (P<0.01); with HL animals being more sensitive to environmental fluctuation. Primiparous ewes had 10 to 13% smaller litters (P<0.01) than ewes at later parities. The repeatability for litter size was 0.51 while the within line 0.33, 0.15 and 0.24 Heritability was 0.62. for LL, Changes ML, in and HL, respectively. survival were due to Prolificacy-Year and ewe weight gain during gestation (P<0.01). Survival in the HL was 44% lower than that of ML and LL in poor years. Lamb survival for quadruplets was 86, 67, 44, singles, and twins, triplets and 31% respectively. Lower survival of their lambs (64.9%) as compared to later parities (74.6%) (P<0.01), was recorded in primiparous ewes mainly due to low body weights. Two main causes associated with lamb mortality were studied: ewe weight gain during gestation and lamb birth weight, which have a relative contribution of in the determination of this trait…dst

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
