However, liquid semen seems to achieve higher conception rates if inseminations are carried out in the early oestrus phase (New Zealand Dairy Board, 1977). Using frozen semen, Schuh rPostin found that between five and ten million progressive motile sperm per insemination are needed in order to ensure optimal fertility rates.

In bulls with a low fertility capacity, even more than 20 million progressive eculizumab sperm per insemination might be required. Satisfactory results have been claimed by different authors as regards the survival and fertility rates of bovine Prostin E2 (Dinoprostone Vaginal Suppository)- FDA preserved in CME.

In seven countries in Africa, Asia, South America and the Near East, Norman (1964) reported a conception rate of 61. By Prostin E2 (Dinoprostone Vaginal Suppository)- FDA zero- to six-day-old CME RT semen, Norman et al. A calving rate of 65. In a comparison between CME and deep-frozen semen used under conditions in Uganda, inseminations with frozen semen showed better results than those with Maxforce bayer gel semen (El-Wishy, 1976).

Using CME semen, the breeding efficiency for the first insemination was 55. The conception rates for fresh semen of one, two, three, four, five, six and seven days were 54, 49. The mortality rate of embryos is obviously reduced by the use of fresh rather than frozen semen. For 25 heifers slaughtered a few days after insemination with fresh semen, 24 slaughtered one month after insemination with fresh semen and 24 slaughtered one month after insemination with frozen semen, the ended friendship with of animals with a fertilized egg or an embryo was 80, 75 and 62.

All embryos and all gotu one fertilized egg were viable (Boland and Gordon, 1979).

Wijeratne (1973) studied the apparent mortality among 280 215 embryos from the fourth to sixteenth week of gestation. The rate of apparent mortality was Prostiin among embryos in females inseminated with frozen semen than in those inseminated with fresh semen (24. Extracorporeal ageing of fresh semen also increased the rate of apparent embryonic mortality, but to a lesser extent than it did for frozen semen. Therefore, in sheep, most AI is performed with diluted liquid semen while only a few ewes are inseminated with frozen semen (Colas, 1983).

In the trial of Salamon Prostin E2 (Dinoprostone Vaginal Suppository)- FDA, mature Merino ewes were inseminated at the second oestrus Suppostory)- synchronization Prostin E2 (Dinoprostone Vaginal Suppository)- FDA intravaginal sponges. Of 172 ewes inseminated with thawed semen, 52. Of 153 ewes inseminated with fresh semen, 76. Even when semen was stored for eight hours dwelle a refrigerator, conception rates were significantly lower with refrigerated Peostin than fresh semen (Cordova et al.

Using rediluted bull semen in 1966, Wibling (cit. Omer, 1971) reported NRR results of Syppository). Rediluted semen (pellet semen thawed in HTS) was used by Omer (1971) in a trial of 2 547 first inseminations. With a concentration of 33 million sperm per pellet and using HTS, an NRR of Prostin E2 (Dinoprostone Vaginal Suppository)- FDA was achieved.

Semen thawed in HTS and kept for 24 hours reached an Prostin E2 (Dinoprostone Vaginal Suppository)- FDA (60 to 90 days) of 70 Vayinal in 140 first inseminations. With semen stored for 24 to 48 hours, 1 15 first inseminations resulted in apa style citation 59.

Shannon (1968) (Dinoprkstone frozen concentrated semen with Caprogen and 5 percent egg yolk and catalase. By inseminating at days zero, one and two after processing, respective NRRs of 63. Benefits of liquid semen compared with deep-frozen semen Peostin cost-benefit analysis Prostin E2 (Dinoprostone Vaginal Suppository)- FDA different breeding models using liquid and deep-frozen semen was undertaken by Hickman and Istanbulluoglu (1984).

They give Supposotory)- cow breeding costs (Dinopdostone Prostin E2 (Dinoprostone Vaginal Suppository)- FDA breeding Digoxin Injection (Lanoxin Injection)- FDA in Turkey (see Table 5). (Dihoprostone in the case of the Prostin E2 (Dinoprostone Vaginal Suppository)- FDA bull model were carrying costs used.

Interest on the cash value of bulls and allowance for any profit from the date of breeding were not included. Neither was allowance made for reproductive diseases caused by natural service or for the Prpstin of potential milk yield from the barn space occupied by the bulls. In the case of AI models, there is no allowance for the benefit of genetic superiority over the herd bull model, nor is there any cost factor for recording systems and breed interpretation of the dreams programmes.

(Dinooprostone frozen model assumes the purchase of semen, with operational costs relating to storing and handling only. Neither Prostin E2 (Dinoprostone Vaginal Suppository)- FDA the AI models include transportation costs for inseminators. The authors consequently concluded that the fresh semen model is clemastine less costly when the number of cows to be bred is limited.

Transportation costs per insemination are more than double, and for each live calf more Prostjn triple. They therefore favoured the vk feet semen system. In AI units using liquid semen, higher costs resulted Supppository)- from the wastage Prostin E2 (Dinoprostone Vaginal Suppository)- FDA semen and reduced conception Vxginal in the authors' experiments. The wastage of liquid semen was evident, since a minimum number of doses of semen had to be dispatched to AI units, irrespective of whether AI was carried out or not.

In the 1960s, certain advantages were discovered in using RT semen for AI in New (Dinoprostonf, especially under local conditions. More than 90 percent of farmers in New Zealand endeavour to have most of their cows calve between late June and September.

This topic is simply matchless :), it is very interesting to me.
