Judul: Gambaran Diferensial Leukosit Anak Domba yang Dilahirkan oleh Induk dengan Perlakuan Superovulasi sebelum Perkawinan
Abstrak: Superovulation is the increase in the number of ovulating follicles. The research was conducted to determine the effect of superovulation and litter size on total and differential of leukocyte in lambs born to superovulated ewes before mating. The data of the research were drawn from 18 lambs with body weight ranging from 3 to 4 kg from 12 ewes. Twelve ewes with body weight ranging from 20 to 25 kg were assigned into a randomized design with 2×2 factorial arrangement. The first factor was superovulation and the second factor was litter size. Estrous cycle was synchronized by injection of PGF2α 10 mg/sheep twice at 11 days intervals. Superovulation was induced by injection of PMSG 100 IU/sheep. The ewes showing estrous sign were then mated naturally. Futher, sheep were pregnant and gave birth 18 lambs. The blood samples were drawn from 1 day old lambs. Parameters measured in this research were total of leukocyte and percentage of neutrophil, basophil, eosinophil, lymphocyte, and monocyte in the new born lambs. Data were analyzed using a General Linear Model. The result showed that superovulation of the ewes prior to mating increased leukocyte, but did not affect neutrophil and ratio N/L in lambs from superovulated ewes. From this study it can be concluded that superovulation of the ewes prior to mating increased the immunity of the lambs, while superovulation or litter size did not affect stress on lamb

Judul: Gambaran Sel Darah Merah, Hematokrit, dan Hemoglobin Induk Domba pada Awal Kebuntingan yang Disuperovulasi
Abstrak: Superovulation is a procedure when an animal is induced (usually through use of injectable hormones) to ovulate multiple ova. This study was conducted to study the blood profiles of nonsuperovulated and superovulated ewe during early pregnancy. The data were collected from May until June 2011. A total of 18 ewes weighing between 18–23 kg were divided into 2 groups. The first group was control (without superovulation) and the second group was superovulation (injected with PMSG and hCG). Variables measured were number of red blood cell, hematocrit, and hemoglobin concentration. Blood samples were drawn from the jugular vein for 30 days during early pregnancy, i.e., on days 1, 3, 6, 9, 12, 15, 30. The results showed that nonsuperovulated ewes had the lowest number of red blood cell, hematocrit, and hemoglobin concentration as compared to superovulated group. The number of red blood cell, hematocrit, and hemoglobin concentration increased on day 30. It was concluded that superovulation of ewes prior to mating could increase the number of red blood cell, hematocrit, and hemoglobin concentration.

Judul: Closed Knight’s Tour pada Papan Catur Berbentuk Persegi Panjang dengan Ukuran Maksimal 8 × 8
Abstrak: Closed Knight’s Tour merupakan langkah kuda yang mengunjungi setiap kotak pada papan catur tepat satu kali dengan langkah kuda berawal dan berakhir pada kotak yang sama. Graf yang terbentuk dari closed knight’s tour dinotasikan sebagai graf G(m,n), dengan m adalah banyaknya baris dan n adalah banyaknya kolom. Graf tersebut memuat Hamiltonian cycle. Sebuah graf terhubung G adalah graf bipartite jika dan hanya jika graf tersebut tidak memiliki cycle dengan panjang ganjil. Papan catur yang memenuhi syarat cukup untuk memiliki closed knight’s tour adalah papan catur berukuran 5 × 6, 5 × 8, 6 × 6, 6 × 7, 6 × 8, 7 × 8, dan 8 × 8.
