Evaluation of the artificial insemination programme for small-scale dairy farms in Malawi por Chagunda, Mizeck G.G., Wollny, C.B.A., Bruns, E., Kamwanja, L.A.

“…Data available from the Blantyre milk-shed area showed that the government controlled artificial insemination program applies a breed substitution strategy resulting in an increase of high grade Holstein-Friesian x Malawi Zebu crosses (>7/8 Friesian) from 388 in 1985 to 1228 cows in 1994. The semen is locally produced at the national AI center. …”

Constraints to Development of extensive livestock systems: Experiences from southern Ethiopia por Coppock, D. Layne

“…However, the Boran today are in a state of considerable change that has been induced primarily by a long-term decline in the per capita supply of cows' milk, the traditional dietary staple. This inbalance has resulted from steady growth in the human population in combination with density dependent fluctuations in cattle production. …”

Evidence of differences in trypanosusceptibility in East African Zebu cattle por Rowlands, G.J., Mulatu, W., D'Ieteren, G.D.M., Nagda, S.M.

“…Despite deficiencies in these data brought about by the high levels of drug resistance, dam-offspring regression analysis indicated genetic associations between dam and offspring PCV when corrected for parasitaemia and treatment frequency. In other words, cows with abilities to maintain PCVs at higher levels than others appeared to pass on this same characteristic to their calves, particularly once calves approached two years of age. …”
