This experiment was carried out to determine the nutritional status of sheep and cows and the effects of feeding status on reproduction and milk yield. For this purpose, 14 sheep and 27 cow farms were selected as pilot and the criterion for the selection was that the sheep and cow farms should include at least 50 sheep and 5 cows respectively.

While straw was used in all cow farms and this was followed by milk feed, wheat, brain, sugar beet pulp, barley, cotton seed meal and dried alfalfa but the ratios of feeds in diets were different. While straw and barley were used in most sheep farms. Other feeds were added to diets in a few farms.

Sunflower and cotton seed meal used in diets had low content of energy and protein but the content of crude fiber was determined to be higher. b caroten levels were low in dried hay as alfalfa and vetchling. Crude fiber levels of diets were high, but other nutrient levels of diets were different. It was observed that rations used in farms were not programmed according to feed requirement of animals but were adequate for only mecanical satisfaction.

When compared with low milk yield cows, conception rate was lower in high milk yield cows inseminated at peak period of lactation but conception rate increased in further inseminations. Thus, mean conception rate was balanced. While, there was not marked abortion in cow farms, low abortion levels in sheep farms depending on travmatical reasons were observed.

In general, feeds were stored under suitable conditions, whereas sugar beet pulp was stored under primitive conditions. Because of this, the highest mold and bacteria counts were detected in sugar bet pulp. The contamination with mold and bacteria in other feeds was determined not to be at dangerous levels.
