[Carbamide phosphate in sheep feeding].

Experiments were carried out in 1975 with feeding urea-phosphate to year-old sheep of the Black face Plevenska breed in the course of three months. Results showed that giving urea-phosphate instead of urea produces a favourable effect on the digestibility of nutrient matter, the coefficient of digestibility of the test group sheep rising as follows: for fats--11.12 at p less than 0.001; for proteins--5.10 at p less than 0.01; for phosphorus--10.0 per cent (p less than 0.01); etc. Dietary nitrogen was used 83.05 per cent (p less than 0.001) better when ureaphosphate was offered. A ration composed of meadow hay 1000 g, maize mash 300 g, barley mash 100 g, lime 5 g, sodium chloride 10 g, and urea-phosphate 15 g influenced favorably productivity of sheep, the weight gain rising by 90 per cent (p less than 0.001). Mutton obtained from sheep fed urea-phosphate the rate of 0.4 g per kg proved of higher quality, containing more protein and less fats, the dressing percentage being 3.5 per cent higher.
