The Effects of Fetal Number on Maternal Serum Progesterone and Estradiol of Ewes During Pregnancy

ABSTRACT: Twenty nine ewes with similar weight and age were used to study the contributions of fetal number to circulating concentrations of progesterone or estradiol during whole pregnancy. The ewes were injected with 1 nil synthetic prostaglandin PGF2(x (PFOSCAviti, Inter...13) isia. and were repeated on d l I from the first injection to synchronize the estrous cycle. Based on the number of lambs born at parturition date, the ewes were assigned into 5 groups (0. I, 2, 3, and 4) with n = 3, 12, 9, 4, and 1, respectively. Blood samples were collected every other week for progesterone and estradiol analyses using radioimiuunoassay. Simple correlation was used to determine the relationship between, the fetal number and serum progesterone or estradiol colicentratiolis. The results of the experiment. showed that fetal number correlated with the maternal scrum progesterone concentrations either during the first half of pregnancy (

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

The Role of Turmeric Powder in Lipid Metabolism and Its Effect on Quality of the First Quail\u27s Egg

This experiment was conducted to determine the role of turmeric powder in lipid metabolism andits influence on the quality of the first quail\u27s egg. Sixty female quails were assigned into a completelyrandomized design with four treatments (levels of turmeric powder i.e., 0; 13.5; 27; and 54mg/quail/day) and each treatment used 15 quails. The treatment was conducted for 60 days. Parametersmeasured were proximate analysis and the quality of the first layed eggs. At the end of the experiment,serum cholesterol and triglyceride concentrations, abdominal and pectoral fat weights, and feedconsumption were measured. Chemical analysis showed that turmeric powder contained 7.97%curcumin. Supplementation of turmeric powder lowered serum cholesterol and triglycerideconcentrations, egg fat and protein contents, haugh unit and yolk index, but did not affect feed intake,abdominal and pectoral fat weights, egg weight, eggshell weight, eggshell thickness, and egg shellindex. However, quails supplemented with turmeric powder showed a variation in egg laying delayranging from 1 to 16 days. Quails supplemented with 54 mg/d turmeric powder had the highest follicleshierarchy. It was concluded that supplementation of turmeric powder with the level of 54 mg/quail/daydecreased lipid content of the egg and improved the other egg quality parameters

Thyroid Hormone and Blood Metabolites Concentration of Gilts Superovulated Prior to Mating

An experiment was conducted to study injection of pregnant mare serum gonadotrophin (PMSG) and human chorionic gonadotrophin (hCG) as superovulation agent in gilts to improve thyroid hormone and blood metabolites concentraton. In this experiment, 48 gilts were assigned into four groups of twelve gilts injected with PMSG dan hCG dose levels of 0, 600, 1200 and 1800 IU/gilt. Injections were conducted three days before estrus. During  gestation, gilts were placed in colony pigpen. On days 15, 35, and 70 of gestation blood collected to determine triiodothyronine, tetraiodothyronine, tryglicerides, glucose, protein and bood nitrogen urea concentration. The resuts showed that superovulation dose levels of 600 to 1200 IU/gilt increased concentration of thyroid hormone (triiodothyronine and tetraiodothyronine/thyroxin) and blood metabolite (triglycerides, glucose, and protein), but decreased blood urea nitrogen in gestation ages 15, 35, and 70 days.  It is concluded that superovulation with dose of 600 to 1200 IU can improve of gilts metabolite hormone and blood metabolites.

Pengaruh pemberian somatotropin pada saat kebuntingan terhadap pertumbuhan anak tikus

Mortality, growth and conception development after placentation are affected by capacity and placenta function which are influenced by hormonal and growth factor to succed pregnancy till birth. Growth hormone is protein or polypeptide hormone. It influences protein metabolism, increases amino acid up take, carbohydrate metabolism, gluconeogenesis, fat mobilizatin, minerals metabolism and the development of cartilage that will lead to growth. The purpose of this research is to observe the effectiveness of somatotropin on the growth of fetus. Forty pregnant rat were divided to 4 groups, they were K (not given somatotropin), A (given somatotropin 9 mg/kg BW at 12 to 20 days of pregnancy), B (given somatotropin  9 mg/kg BW at 2 to 11 days of pregnancy), C (given somatotropin  9 mg/kg BW  at 2 to 20 days of pregnancy). Parameters observed were ovulation rate, implantation rate, development/growth of uterus and placenta, size of fetus, and pups growth. The result showed that somatotropin could increase implantation succed, development of uterus and placenta that are followed by good performance of reproduction during pregnancy and also birth body weight pups.Keywords: Somatotropin, Pregnancy, Pups
