N'Dama
N'Dama is a domestic cattle breed from West Africa . Other names are Boenca or Boyenca ( Guinea-Bissau ), Fouta Jallon, Fouta Longhorn, Fouta Malinke, Futa, Malinke, Mandingo ( Liberia ), N'Dama Petite ( Senegal ).
Originally native to the highlands of Guinea , they can also be found in southern Senegal, Guinea-Bissau, Gambia , Mali , Côte d'Ivoire , Liberia, Nigeria and Sierra Leone . Because of their tolerance to Nagana , they can also be kept in areas with tsetse flies . They also show good resistance to ticks and the diseases they cause and to the stomach worm Haemonchus contortus .
In the 19th century, some animals from Senegal were brought to St. Croix to be crossed with Red Polls , which resulted in the Senepol cattle breed .
Reproduction and development
The age for first calving is 3.5 years in the upper Casamance and is slightly lower in the lower and middle Casamance. The average time between pregnancies is 16-17 months in the middle and upper Casamance and about 19 months in the lower Casamance. 80% of the calves are born in the second half of the year. The miscarriage rate is between 10 and 20%, resulting in an average calving rate of 56%. The calves are weaned at around 12 months and, if necessary, castrated at 3 years of age. The breed has an overall annual death rate of 12%, for calves under one year old it is around 30%. For one to two year old calves the rate is 15%, for two to three year old calves 5% and 2% for adult animals.
