The value of livestock increased annually after 1981, but the
decreases in livestock in the early revolutionary period were
such that by 1985 the overall value of livestock remained below
the 1976 level. Severe shortages of meat and eggs, coupled with
high demand and the absence of price controls, encouraged the
raising of livestock and were expected to improve livestock availability.
Livestock-raising methods were generally unsophisticated. Sheep
and goats were kept by nomadic tribesmen and by sedentary villagers
who supported a few animals as a sideline to farming. These animals
had diets of grass and shrubs that often left them diseased and
malnourished; in turn, the herders obtained little profit in the
way of meat, milk, hair, and hides.
