Heterogeneous acid on the role of ruminant livestock nutrition

Days of testing, the results of Feeding cattle heterogeneous acid than the control group, a 1 day prolific standard milk 1.4kg,[link widoczny dla zalogowanych], which yield 7.84. Feed efficiency was also improved. Rogers et al (1989) comprehensive coverage of goods in the United States, 43 in the Feeding of heterogeneous salt farm on the lactation performance. The 5P50 tested Holstein cows, the average yield for the 7j80 ~ children 190Lg. The feeding and management of rangelands tested way of mutual differences,[link widoczny dla zalogowanych], there are feeding, but also dissipate into the atmosphere style | 2 to 6 times a day feeding, milking three times per J 2 soy basal diet of corn silage and alfalfa silage , Wing Skill thousands of grass, alfalfa hay and concentrate mixture sets. Feed the field different, but diet formulations can meet or slightly exceed NRC recommended nutrient allowances for a trial period of 3 to 4 months. The results add 9 ¢ò heterogeneous acid increased milk yield, although the magnitude of the yield test is not consistent. Test ¢ó and ¢ô, respectively, in the daily milk yield increased O. 1¡¿. 8kg, the {what-three trials by the middle of the mouth of bovine lactation milk yield _ spider respectively 5.4,2.7 and 3.6kg, first-born cow daily milk yields increased by an average 1.3kg. Measurement results show that the heterogeneous acid Feeding fat yield and milk protein increased the yield of the cow's health and reproductive performance without adverse effects. Test group of cattle a lower incidence of metabolic disease. Feeding the difference seems to increase the milk of heterogeneous acid stomach, animal husbandry, not number the first volume skills ¡§ Man! Thirteen l! Johnson.

Third,[link widoczny dla zalogowanych], the use note to J1] heterogeneous acid as feed Tim Sh¨ª f agent Ge must pay attention to some of its features. (1) should be started 2 weeks before parturition cows fed, otherwise yield poor results. From an economic point of view, in the lactation period, 8O days after the heterogeneous acid feed can be stopped. (2) use of heterogeneous acid should be strictly controlled doses. At first dose should be halved for two weeks. (3) ears ago, the various types of heterogeneous acid products on the palatability of the cows are still not ideal. they should be mixed with other units and then fed diets , fed by newly added to the standard amount of most agents' best day dose into multiple meals. some cattle to be taught by more days to adapt to the intake system (4). rumen microorganisms to adapt to heterogeneous acid additive to cow reaction yield of milk, the need for a long period of time. According to reports, ¡»into heterogeneous acid to achieve the maximum increase rate of milk will take 40 ~ n0 days. Fourth, the mechanism of heterogeneous acid is a VFA points, no doubt can be used as livestock energy source. heterogeneous acid is an important nutrient rumen bacteria or growth factors, Feeding can increase the number of cellulolytic bacteria and activities. heterogeneous acid biosynthesis can be seen as a precursor amino acid, when the diet in Valeriana acid, leucine and isoleucine to be added such as low natural ga help to increase the protein into (HuIt3c, etc., 19j). Quispe (i982) and Gorosito (1985) and other evidence, will be provided to enhance rumen bacterial activity commercial plant cell wall digestibility,[link widoczny dla zalogowanych], and Peijia! rumen fermentation rate and the production of acetic acid, volume ratio. There are two tests showed that the acetic acid yield was increased by 10 and 40, respectively. Another three trials that the sheep rumen acetic acid yield increased 3e,¡¿ 8% and 26, while no increase in acid production. acetic acid is the body's biochemical reactions important participant in the citric acid cycle, which account for at least the total oxidative metabolism of ruminants: G ~ 4c. it is also the main station into the milk fat precursors. FeIx (] 980) and Fie0r1984) and other research Ben kick, volatile fatty amine salts, amino acids not only as a precursor of Quebec, but also affect the absorption of the metabolic process. Feeding cock Structure acid can increase the concentration of growth hormone in the blood, reduce blood fine,[link widoczny dla zalogowanych], reduce the stimulus of insulin release. there is that the heterogeneous acid ultimately Africa by increasing the dietary energy to stimulate islet Chong (aoa-insuiinstimulatin faint energy) release, to improve breast the utilization of energy and nutrients, thus substantially improving milk production. Although ruminant digestion and metabolism is a very complex physiological problems, but the role of Feeding mechanism of heterogeneous acid feeding effect has not been fully identified nor J all the same, although most cases a positive effect. but you can believe that with further testing and exploration, more to grasp the mechanism and application of methods can be effectively used for its meat and milk production. reference to race sail offer smoked pole A dark eye of an ax
