Abstract

Abstract. This study was carried out to determine the optimum fertility and fertile period using the number of spermatozoa, oviduct condition and timing of insemination of native rooster spermatozoa. Ninety six commercial Isa brown pullets and nine kampung roosters were used in this study in a 3×2×2 factorial arrangement with one bird in a cage constituting a unit. The factor levels were the number of spermatozoa (50, 100 and 150 million/0.1 ml), oviduct condition (hard-shelled eggs and free hard-shelled eggs), and timing of artificial insemination (in the morning, at 7 AM and in the afternoon, at 4 PM).  The results showed that among the treatments there was no significant interaction to fertility and fertile period. Insemination with 50 million sperm number seemed to be the same result with the other 2 treatments. Oviduct condition had a highly significant difference on fertility and fertile period percentage, and timing of insemination did not differ between morning and afternoon.  In conclusion, the only oviduct condition (free hard-shelled eggs) was the best results for insemination in terms of fertility and fertile period of native roosters.  It is recommended that for the maximum fertility and fertile period, hens should be inseminated with 50 million spermatozoa, free of hard-shelled eggs and insemination performed in the morning or in the afternoon. Keywords: timing of artificial insemination, fertility, fertile period, semen dose, oviduct conditionAnimal Production 14(1):32-36, January 2012

Abstract

AI for cattle has been develop in Indonesia in contrast, AI for small ruminants (sheep and goat) are less developed. Its due to the lack of facilities, processing and packaging during storage. This research aims to compare the effectivity and efficiency of two different packaging technique (test tube and straw). Test tube and 0.25 ml mini straw were tested . Semen was obtained from adult PE buck (3 yr) after collection by using  artificial vagina. The fresh semen was then evaluated and diluted 5 folds with 2.9 percent Na-citrate. Diluted semen then packed in test tube and mini straw, and stored in refrigerator (100C) for 7 days. Observations were done everyday on sperm motility, abnormality and percentage of  live sperm. Observation were made at 370C. Observation on fresh ejaculate showed that semen has 6x 109/ml concentration, 90 percent motility, 8 percent abnormality and  95 percent  live sperm. Five folds dilution reduced sperm concentration to 1.2 x 109/ml, but did not change sperm motility, abnormality and percent of live sperm. Sperm was then packed according  to the treatments. Storage in both packaging did significantly reduce  (P<0.01) sperm motility and percent live sperm, but not for sperm abnormality. All sperm stored in test tube were classified death at day 5 storage. However, sperm in the straw were remain live eventhough the percentages was low. It can be concluded that straw has a better result than test tube. Eventhough sperm motility was extremely low, it remains valuable for cervical insemination.

Abstract

Fifteen thin tail ewes were used in to study of contribution of maternal serum estrogen concentration this in relation to estrous duration with inducted of PMSG. The first step, all experiment ewes were injected prostaglandin (7.5 mg luprositol per head)  i.m. as much twice of interval day 11 to homogeneity follicle growth phase. In the estrous observed was estrous (700 IU duration, then blood sampling taken out of vena jugulars to analyses of estrogen. The second step, all experiment  ewes were inducted PMSG  (700 IU per head), then in the estrous observed was same as the first step. The result of experiment show that induction of PMSG  influence to  maternal serum estrogen concentration has different significantly (P<0.01)and estrous duration has different significant (P<0.05).Maternal serum estrogen concentration prior and post of  induction of PMSG contributed 25.28 and 57.12 percent, respectively. It was concluded that the estrous duration in relation  to increased maternal serum estrogen concentration. (Animal Production 3(1): 40-44 (2001) Key Words: Estrogen, estrous, ewes

Abstract

A study on the effect of AI time on the fertility of layer hens was carried out. Semen was collected from eight kampung roosters, with age ranging from 12-18 months.  Completely Randomized Design was used to analyze the data obtained.  Every eight hens (n=8) was inseminated intravaginally at 0-2 hrs, >2-4 hrs, > 4-6 hrs and >6-8 hrs after oviposition.  The results showed that insemination time did not affect  (P>0.05) the percentage of fertility from days 2 to 20.  However, the insemination time affected (P<0.05) the percentage of fertile eggs from days 2 to 9 and it did not affect (P>0.05) the mean duration of the fertile period.  In conclusion, the time of insemination at 0 – 2 hours after oviposition gave the best fertility.  It is recommended that for the best fertility flock inseminations should be performed at a time of 0-2 hours after an egg is laid every 9 days.

Abstract

The use of various levels of glycerol as a cryoprotective agent for freezing kampung chicken semen was examined with respect to intravaginal insemination.  There was a significant (P<0.05) effect of various levels of glycerol (4, 8, 12 and 16 %) on motile spermatozoa, but there was no significant effect on fertility.  It was concluded that the use of glycerol for preservation of kampung chicken semen in liquid nitrogen gave satisfactory cryopreservative results on    motility of thawed kampung chicken spermatozoa, but failed to produce fertile eggs.
