This book was released on 2011-10 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional traits are the characters of an animal which increase the efficiency not by higher output of product but by reduced cost of input. Udder and reproductive disorders are the imperative functional traits which causes major losses in milk production. Reproduction disorders affect the herd life, reproductive efficiency of cows and are responsible for removal of the cow from the herd. Crossbred cows appear to be more prone to infections and disorders as compared to indigenous breeds. Karan Fries cow is a crossbred of Holstein Friesian and Tharparkar (India) developed at National Dairy Research Institute, Karnal, India. Incidence of abortion, still birth, dystocia, retained foetal membrane, metritis, endometritis, anoestrus, repeat breeding, pyometra and other reproductive disorders in Karan Fries cows were evaluated. Production and reproduction performance traits were found to be influenced by reproductive disorders. Repeatability of anoestrus and abortion were moderate to high in second and third lactation. Metritis was the most severe reproduction disorder. Overall incidence of reproduction disorders was lower in F1 than interbred genetic group of Karan Fries cows.

This book was released on 2013 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dairying is a vital enterprise and important source of income generation for rural families of many developing countries of the world. Although, Holstein is imported by many tropical countries with the idea to improve the milk production but their performance in these environmental conditions is considerably low compared to the temperate environments. The expression of the inherit genetics worth differs from one environment to another and is significantly swayed by non-genetic factors. Environment and genetic (G x E) interaction plays key role in the expression of full genetic worth of an animal. The range of comfortable temperature in lactating Holstein cattle is between 4-24oC. Above 24oC, heat stress effects can be observed on the cattle, and milk yield markedly decreases above 27oC. In most of the tropical and subtropical countries the ambient temperature rises above 40 C, which is obviously suboptimal for Holstein to maintain their health and production performance. The present study was designed to investigate the effect of various environmental and genetic factors on various productive and reproductive traits of this breed under sub-tropical conditions."
