Assesses the effect of cow-calf association and continuous suckling on the resumption of oestral activity; and monitors the temporal patterns of plasma progesterone during the post-partum period in grazing Ethiopian Small East African Zebu cows under uncontrolled mating.

Zerbini, E.Gemeda, T.Tegegne, AzageGebre-Wold, A.Franceschini, R.[Effects of work and diet on progesterone secretion, short luteal phases and ovulations without estrus in postpartum F1 crossbred dairy cows]Effects of work and diet on progesterone secretion, short luteal phases and ovulations without estrus in postpartum F1 crossbred dairy cows

Forty pregnant crossbred cows (20 Holstein-Friesian X Boran and 20 Simmental X Boran) were assigned to a 2x2 (work X diet) factorial experiment as follows: supplemented-non-working (SNW), supplemented-working (SW), non-supplemented-non-working (NSNW) and non-supplemented-working (NSW). Working co...

Ten Boran and 12 Boran X Friesian bulls with a mean (+standard error of the mean) age and body weight of 20.2+0.5 months and 225.5+2.5 kg were used over a 1 year period to determine the effect of plane of nutrition and season on body and testicular growth and on semen traits. Within genotype, bul...

This study examines superovulatory response, embryo recovery rates, embryo quality, return to natural estrus, and patterns of progesterone secretion and its relationship with superovulatory response and embryo quality in Boran cows after treatment with either a human menopausal gonadotropin (Perg...

This study was conducted in the central highlands of Ethiopia during 1990-92 to examine the effects of diet and partial suckling on lactation and reproductive performance of Boran (Bos indicus) cows. Primiparous Boran cows were allocated to dietary supplementation or no supplementation with eithe...
