Fat should be fed appropriately The fat content of the dairy diet should not exceed 7% of the dry matter of the diet.The supplement is usually 3 ~ 4%.Calculating the amount of fat added The exact amount of fat a cow needs depends on the amount of milk fat produced.If a cow produces 36 kg of fresh milk per day, 3.5% of milk fat and 1.27 kg of milk fat per day, 1.27 kg of fat should be added to the diet in order to maintain the normal condition and continuous production level of the cow.Do not use only one type of fat in the production of feeding different sources and types of fat.For example, using soy as the sole fat in the diet can lead to excess rumen biodegradable protein, affecting feed intake.Gossypol poisoning occurs when cotton seeds are fed more than 3.6 kg or 4.5 kg a day, resulting in visceral bleeding and reduced reproductive capacity.Liquid grease is not suitable for feeding dairy cattle.Note the interaction between fat and roughage When adding fat consider the type of roughage that makes up the diet.When corn silage was used as the main forage, only adding cattle and sheep oil could increase milk yield.Alfalfa and cottonseed have a good synergy, alfalfa can speed up the digestion of cottonseed.Poor palatability can be avoided by gradually increasing the amount of fat fed.The first feeding 1/3, in three stages to the full amount, usually takes 3 to 4 weeks.Fat can be added gradually during the dry milk period.It is best to add fat to a fully blended diet, fully blended with other ingredients.(Li Weiqi) statement: the copyright of this article belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through email, we will promptly deal with.Email address: jpbl@jp.jiupainews.com
