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.

Abstrak: Local sheep is one of the animal genetic resources which is potential to be developed in supporting national meat supply. Local sheep has some superiorities such as twinning birth, early mature age and non seasonally breeding. Nevertheless, instead of these superiority, some problem still occurred as lacking of lamb survivability rate, low carcass percentage and high variances both genotype and phenotype parameters. The objectives of this study were to find the relationship between ewe age and its productivity, and ewe body measurements and its milk yield on grazing system. This study was conducted in the Jonggol Animal Science Teaching and Research Unit (JASTRU), Singasari Village, Bogor District, from June up to November 2007. As many 100 lactating ewes, on 1 to 4 years of age, were used in this study. Sheep were reared on grazing system from 9 a.m. to 4 p.m. and housed at night. The results showed that ewe age highly significant affected the body weight after lambing (p<0,01), milk yield (p<0,01), total birth weight (p<0,01) and total weaning weight (P<0,01) but did not significant for litter size. Breast circle, udder base circle, and udder height showed strong relationship in predicting 3 to 5 year ewe milk yield (p<0,01). The most productive ewes was 3 to 4 year ewes group.

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.
