The Effects of Corpora Luteal Number on Serum Progesterone and Estradiol of Ewes During Luteal Phase of Estrous Cycle and Pregnancy

ABSTRACT Two experiments were conducted to study the effects of corpora luteal number on maternal senint concentrations of progesterone and cstradiol during luteal phase of estrous cycle and pregria.ncy. The experimental ewes Wer0 injected twice with I ml PGF2 to destroy previously existed corpora lutea The number of corpora lutca was counted by laparoscopy 5 days after the onset of estrous cycle. Blood samples were collected weekly during the estrous cycle and biweekly during pregnancy for lionnone analyses using raclionnuatinoassay, Simple correlation was used to determine the relationship between the number of corpora lutea and pi ogesterone or estradiol concentrations. Progesterone concentrations increased with the number of corpora linca dui tug the lineal phase of estrous cycle (

Contributions of Maternal Serum Progesterone and Estradiol Concentrations or Corpora Luteal and Fetal Number to Mammary Growth and Development of Ewes During Pregnancy

ABSTRACT Sixteen ewes with similar weight and age were used m an experiment, and injected twice with PGF2 before being bred. Number of corpora lutea was detennined 5 d after the onset of estrous cycle by laparoscopy. Number of ewes haying 0, 1, 2, 3, and 3 corpora lutea were 3, 2, 5, 4, and 2, respectively. At parturition date, the number of ewes gave birth to 0, 1, 2. 3, and 4 lambs were 3, 6, 4, 2, and l, rcspectivdy. Blood samples were collected every other week during pregnancy for progesterone and estradiol analyses with radiounmunoassay. At parturition date, the experimental ewes were sacrificed and the mammary glands were excised for determination of dry-fat-free tissue (DFF0. Multiple regression and correlation was used to determine the relationships of serum progesterone and estradiol concentrations and of corpora luteal and fetal number with mammary Keywords: Sheep, Corpus luteum, Fetal number, Progesterone, Estradici, Mammary Growt

Performance of Pepper Post Harvest Machines

The purpose of this study was to learn technical performance and financial feasibility of a unit of mechanical post-harvest processing of pepper. The equipment used in such a process is thresher, peeler and dryer. The equipment was tested to learn its technical performances. It was found that the threshing efficiency of the thresher was 98% with a capacity of 269 kg fresh pepper spikes per hour and damaged berries of 5.3%. The peeling efficiency of the peeler was 98% with an optimum capacity (in term of fresh pepper spikes) of 224 kg per hour.The financial analysis showed that a unit of mechanical post-harvest processing of pepper with a capacity of 30,000 kg per year needs an investment of Rp. 82,060,000.00. This investment wi/l give an NPV of Rp. 141,605,144; net BIC of 2.37 and IRR value of 81.33%. An intensive and local specific study must be carried out to get appropriate conclusions of such an analysis

Effect of Superovulation on Piglet Production

Sixty gilts with average body weight of 107.80 + 5.10 kg were used in an experiment to study the use of PMSG and hCG as superovulation agent to increase piglet production. In this experiment 60 gilts were assigned into a completely randomized design with 4 treatments of superovulation with dose level 0, 600, 1200 and 1800 IU/gilt. Injections were conducted 3 days before estrus. During gestation, gilts were placed in single pigpen, and maintained to term. The parameters were birth weight, preweaning growth and mortality. The results showed that superovulation dose levels of 600 and 1200 IU/gilt increased the piglet birth weight, litter size, preweaning growth and piglet production at 90 days. It is concluded that superovulation with dose levels of 600 to 1200 IU can improve productivity. (Animal Production 8(1): 8-15 (2006

Effect of Curcumma, Zn-Proteinate, and Cu-Proteinate Supplements on Milk Production of Subclinical Mastitis Fries Holland Cows

The objective of the research was to find out the effect of Curcumma, Zn-proteinate, and Cu-proteinate supplementation on subclinical mastitis status in term of 4% FCM milk production. The research was conducted using 24 heads of lactating dairy cows in Randomized Block Design with six treatments, and four groups of milk production as replication i.e. I= >14 kg/day ; II= 12-13.99 kg/day ; III= 10-11.99 kg/day; IV= <10 kg/day. Treatments were: R1 (Control); R2 (R1 + 2% Zn proteinate); R3(R1 + 2% Cu-proteinate); R4(R1 + 2% Curcumma); R5(R1 + 2% Zn-proteinate + 2% Cu-proteinate); R6 (R1 + 2% Zn-proteinate + 2% Cu-proteinate + 2% Curcumma). Parameters observed were 4%FCM milk production and subclinis status. The results showed that ration supplemented with Curcumma, Zn-proteinate, and Cu-proteinate decreased mastitis subclinic status and 4% FCM milk production increased significantly. Supplementation of Curcumma, Zn-proteinate, and Cu-proteinate resulted is the best for decrease in subclinical mastitis indicator and increase 4% FCM milk production.

Physical and Chemical Characteristics of Maleo Egg in Bogani Nani Wartabone Park

The objective of this study was to examine the size (weight, length, and width) of Maleo egg in Bogani Nani Wartabone National Park.Physical characteristics that measure are : egg weight, egg shell, egg index , yolk, and albumen. Physical characteristics measured were: egg weight, egg shell thickness, egg index, yolk, and albumen. Two fresh eggs were weighed to the electric ohause balance with 400 g the scale 0.01. Two fresh egg were weighed with an electric balance. Length and width off egg were measured by used vernier caliper, egg shell thickness by  tripod micrometer, yolk color by yolk color fan. Length and width of egg used were measured by Vernier caliper, and egg shell thickness by a tripod micrometer, yolk color by yolk color fan. Physical characteristic have been identified eggs weight, egg width, egg length, egg index, albumen width, albumen length, albumen index, yolk width, yolk length, yolk index, weight albumen, weight yolk, egg shell thickness, and shell weight increased by 223.70 g, 104.00 mm, 56.68 mm, 56.41, 113.8 mm, 86.72 mm, 6.07%,  85.30 mm, 69.90 mm, 31.54%, 47.51 g, 110.80 g, 0.02 inch, 19.55 g, respectively.

This study aims to determine antioxidant and anticancer activity of  Clathria basilana extracts. The sponges were collected from Tablolong - Kupang , East Nusa Tenggara , Indonesia . The sponges were extracted with methanol. The crude extract was partitioned by n - hexane. The antioxidant activity of sponge extracts were tested by DPPH method . Anticancer activity of sponge extracts were tested by MTT method. Fraction of methanol - water at concentration of 500 ppm showed antioxidant activity of more than 50 % , while the fraction of n - hexane at concentration of 500 ppm showed antioxidant activity only 10 % . The test results showed that the fraction of methanol - water and n - hexane had anticancer activity of more than 50 % at concentration of 125 ppm.

Progesterone and Estradiol Profil In Ewes Injected With Prostaglandin (PGF,,) in Late Pregnancy

Suatu percobaan telah dilakukan untuk mempelajari profil progesteron dan estradiol pada domba bunting yang korpus luteumnya telah dihilangkan pada akhir kebuntingan.Percobaan menggunakan tiga puluh lima domba yang terdiri dari dua puluh delapan domba bunting (14 ekor disuntik dengan prostaglandin F2, sintetik sedangkan 14 ekor lainnya tidak menerima penyuntikan prostaglandin F2=), dan tujuh ekor domba yang tidak bunting dan bersiklus sebagai kontrol. Domba percobaan dipelihara dalam kandang dengan makananrumput raja kering ditambah konsentrat. vitamin dan mineral Air minum tersedia secara ad libitum. Setiap minggu sampel darah diambil dari vena jugularis dengan menggunakanvacutainer steril untuk mendapatkan serum yang selanjutnya akan digunakan untuk menganalisa progesteron dan estradiol dengan radioimmunoassay fase padat Hasil percobaanmenunjukan bahwa penyuntikan prostaglandin pada akhir kebuntingan pada dornba tidak menyebabkan penurunan konsentrasi progesteron dan estradiol yang bermakna dalam serum induk. Luteolisis oleh prostaglandin F:,. tidak bermakna menurunkan konsentrasi progesteron dan estradiol dalam serum induk. Disimpulkan bahwa pada akhir kebuntinganpada domba, sumbangan korpus luteum terhadap total konsentrasi progesteron dan estradiol serta perkembangan kelenjar susu induk sangat kecil
