Abstract

The aim of the present study was to determine the success rate of artificial insemination (AI), risk factors on pregnancy rate and to propose solutions for the improvement of the AI in a traditional area in Senegal. Of 291 selected cows, 276 were synchronized with the vaginal spiral (PRID®), PMSG...

AbstractFull Text

Reproductive inefficiency is one of major challenges affecting dairy farming in Kenya. This is partly caused by poor estrus detection, delayed determination of unsuccessful artificial insemination (AI) and sub-optimal calving to conception interval. Blood levels of progesterone hormone (P4) are a...

Abstract

The reproductive performance following oestrus synchronization and artificial insemination (AI) was evaluated during autumn and early winter in 60 Nubian goats in the Sudan to determine the best hormonal approach in inducing and synchronizing oestrus. The animals were divided into four groups...

AbstractFull Text

Kenya's smallholder dairy sector produces 85% of the total milk marketed in the country. A major constraint to milk production and number of calves born from the cows is the long calving intervals. Determining non-pregnant cows early by measuring progesterone levels by day 23 after insemination can ...

Abstract

Transrectal ultrasonography and observation of oestrus was carried out on a herd of 40 Nguni cows managed under extensive range conditions. In 30 oestrous cycles, the duration of standing oestrus averaged 25.4 h, and the interval between the end of oestrus and ovulation averaged 12 h. The mean...
