Afework, Y.Tegegne, AzageKassa, T.[Evaluation of the reproductive performance of crossbred dairy cows at the Asella livestock research station, Arsi, Ethiopia]Evaluation of the reproductive performance of crossbred dairy cows at the Asella livestock research station, Arsi, Ethiopia

In an experiment lasting from 1.5 years before, first calving until third parturition, 24 purebred indigenous Bos indicus (Boran) cows and 24 Boran crosses will; Holstein (proportionately 0.50 and 0 75 Holstein blood level) were given a diet composed of Bermuda grass hay and wheat bran (0 65: 0 3...

Presents results of a data collected over a 10-year period on 1,778 service intervals in 1,111 Arsi (Bos indicus) cows at the Ethiopian Ministry of Agriculture ranch to analyse conception rate at first service, interval between services in animals returning for insemination, the number of short c...


Mukasa-Mugerwa, E.Tegegne, AzageTeklu, Y.[Characterization of service intervals and frequency of short oestrus cycles in Zebu (Bos indicus) cows in Ethiopia]Characterization of service intervals and frequency of short oestrus cycles in Zebu (Bos indicus) cows in Ethiopia

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.


Mukasa-Mugerwa, E.Tegegne, AzageFranceschini, R.[Influence of suckling and continuous cow-calf association on the resumption of post-partum ovarian function in Bos indicus cows monitored by plasma progesterone profiles]Influence of suckling and continuous cow-calf association on the resumption of post-partum ovarian function in Bos indicus cows monitored by plasma progesterone profiles

Analyses reproductive data on 4123 inseminations from 2332 breeding records of 1237 Arsi (Bos indicus) cows, collected between 1982 and early 1989 from the Gobe ranch of the Ethiopian Ministry of Agriculture where cows were kept under similar management; and concludes that long post partum anoest...


Mukasa-Mugerwa, E.Tegegne, AzageMesfin, T.Teklu, Y.[Reproductive efficiency of Bos indicus (Zebu) cows under artificial insemination management in Ethiopia]Reproductive efficiency of Bos indicus (Zebu) cows under artificial insemination management in Ethiopia

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...


Jenet, A.Fernández Rivera, S.Tegegne, AzageWettstein, H.R.Senn, M.Saurer, M.Langhans, W.Kreuzer, M.[Evidence for different nutrient partitioning in Boran (Bos indicus) and Boran x Holstein cows when re-allocated from low to high or from high to low feeding level]Evidence for different nutrient partitioning in Boran (Bos indicus) and Boran x Holstein cows when re-allocated from low to high or from high to low feeding level

This study examined the effects of lablab hay and graded levels of wheat bran supplementation on feed intake, feed degradation characteristics, apparent digestibility, milk yield and milk composition of crossbred cows fed forages from cereal crops+legume intercropping (maize/lablab (ML) stover or...


Mpairwe, D.R.Sabiiti, E.N.Umunna, N.N.Tegegne, AzageOsuji, P.O.[Integration of forage legumes with cereal crops. II. Effect of supplementation with lablab hay and incremental levels of wheat bran on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum]Integration of forage legumes with cereal crops. II. Effect of supplementation with lablab hay and incremental levels of wheat bran on voluntary food intake, digestibility, milk yield and milk composition of crossbred cows fed maize-lablab stover or oats-vetch hay ad libitum

A study undertaken to determine the progesterone concentration in the peripheral plasma of pregnant Ethiopian Zebu cows using the ELISA technique.


Mukasa-Mugerwa, E.Tegegne, Azage[Peripheral plasma progesterone concentration in Zebu (Bos indicus) cows during pregnancy]Peripheral plasma progesterone concentration in Zebu (Bos indicus) cows during pregnancy

Presents the results of a study designed to characterize further the temporal patterns of oestrus onset and plasma progesterone profiles during the postpartum ovarian activitity in two groups of Ethiopian Bos indicus (Zebu) cows whose calves were either weaned at 4.5 months or at 7.5 months; repo...

Compares estrus response, estrus response interval and subsequent pregnancy rate in Bos indicus and Bos indicus X Bos taurus cross cows and heifers following estrus synchronization with prostaglandin F2 (PGF2X (a), a progesterone releasing intravaginal device (PR10) (b), and synchro-mate B (SMB) ...
