Study On Feeding Different Proportion Of Alfalfa In The Diets Of Sheep For Production Performance

This paper, added different proportion in the diet of feeding the sheep in alfalfa, studied its effect on blood physiological and biochemical indexes in sheep, growth and digestibility. It aims at seeking for feeding the sheep diets of alfalfa hay in the optimum amount, so as to make full use of the nutrient characteristics of Alfalfa in the sheep which could grow even more rapidly, and provide data support and scientific basis in the production practice. The results showed that:Dietary supplementation of alfalfa hayed in average daily gain, average daily consumption of dry material, gross profit, daily gain and feed weight ratio had certain effect on feeding the sheep, the average daily gain of 40% added weight were significant difference (P<0.05), the best day, its gross profit gain effect,the daily gain highest for 1.15yuan.In the diet of feeding the sheep in alfalfa hay on feeding sheep dry matter, nitrogen, crude fat. acid detergent fiber, neutral detergent fiber, always in the intake of nutrients, and fecal digestibility had certain effect. Adding 40% alfalfa hay on the detergent fiber digestibility was significantly higher than the control group (P<0.05), the overall effect was the best.Urea nitrogen addition of alfalfa hay in the diet of feeding the sheep in the feeding sheep blood (BUN) content, total protein content (TP), glucose (Glu) had a certain impact on blood physiological and biochemical indexes of content, but the difference was not significant (P>0.05). Experiments showed that, adding 40% alfalfa hay in feeding the sheep diets could achieve good results.The test confirmed:adding alfalfa hay diet in sheep should be appropriate, the ratio could not exceed 40%, otherwise it will cause feed waste, reduce economic benefits. Therefore, the best production could be achieved by adding the 40% proportion of alfalfa hay, which in the future could be widely popularized and applied in production.
