Factors affecting milk production in the Butana are investigated. Production records of 353 Butana cows with 1,311 calvings during the years 1943-57 from a governmental dairy farm herd on the north of Atbara, Sudan were analysed. Heifers averaged 44 months old at first calving. The average interv...

The use of imported semen within the Holstein-Friesian cattle population in Kenya has contributed to increased milk production per cow, however, information on how this has impacted on functional traits, particularly early life survival and reproductive performance is scarce. This study evaluated...

The carcass characteristics of Sudanese cattle are investigated in relation to the improved marketing procedures. Results of initial use of meat laboratory involving a total of 31 head of fattened cattle from Western Baggara and Butana bulls were evaluated. Data on beef quality and slaughter by-p...

The aflatoxin (AF) albumin adduct is often used as a biomarker for aflatoxin exposure in humans. An ELISA method previously used for aflatoxin serum albumin in human blood was used to analyse bovine serum samples (n = 22) collected from dairy cattle during an aflatoxin mitigation study in Kenya. ...

Study on the use of imported semen at the Alemaya Research Station was reported. Birth weight, weaning weight, feedlot and slaughter performance of native Boran and crossbred calves were evaluated. Results on comparative performance included.
The blood contituents of Adamawa Gudali and Wakwa cattle were exaluated to determine the haematological values for each breed. The effects of sex and age on the parameters were also examined.

The effects of crossbreeding on production performance are investigated. The performances of local pure lines from West African Shorthorn (WAS) and N'Dama cattle, and their crosses with Santa Gertrudis and Red Poll were evaluated over a period of 4 years. The F1 generation of Santa Gertrudis x WA...

The milk production of five zebu cattle from south-western Ethiopia was estimated. Calves were weighed before and after suckling three times a day, seven days each week. Average daily production for a 14-week period was 11.14, 9.39, 8.11 and 7.37 lb. of milk. Daily gains for calves of these cows ...

Reproductive performance, mortality, growth, and culling and replacement rates based on 20000 calving records were evaluated for grade Boran beef cattle maintained with trypanosomiasis risk in Tanzania. Under ranching conditions, over a 10-year period in this area of high Glossina moistens morsi...
Data collected on number of services per conception (NSC), age at first calving, (AFC), calving interval and calf pre-weaning mortality rate of Boran cattle and their Friesian crosses were evaluated. The NSC was 1.81, 1.61 and 1.69 for Boran, F1 Boran-Friesian and three-quarter Friesian heifers r...
