Livestock holdings were aggregated into Tropical Livestock Units (TLU) (FAO 1972) (9) and added as a single asset.
Livestock ownership, measured in TLU, was low at 4.73 per household and 1.43 per adult household member.

In our case, Mils is the livestock mortality (asset loss, measured in aggregate tropical livestock units or TLU) experienced by household i in locality I in season s.
where TLU is the total TLU of livestock insured and PTLU is the preagreed value of one TLU, so that their product reflects the total insured livestock value.
The size of the domestic herd measured in TLUs was strongly predicted by the number of adults in the household and positively associated with all measures of the consumption needs of households for both households with cattle camps and those without (pooled results shown in Table II).
Nineteen households (95%) fell below the conventional subsistence threshold of five cattle per capita (Kjaerby and Baynit, 1979; Sperling and Galaty, 1990) and 4.7 TLUs per capita (Dahl and Hjort, 1976).
The average primary production of these pastures is 100-200 kg dry matter/ha per year, that is to say a rainfall efficiency use coefficient of 1-4 kg dry matter/ha per year and per mm rainfall, and a carrying capacity of 1 TLU (tropical livestock unit) per 45-275 ha.
The average number of days of grazing per year is about 50, representing a load of 1 TLU per 7.3 ha.
