The constant need to supply the growing global energy demand, leads an increase in generation of greenhouse gases. To circumvent this problem, more and alternative means have been used compose grid. One alternatives, which recent decades has received great attention from researchers, is conversion wave into electrical energy. In Brazil, studies also gained momentum, possibility implementing con...

The aim of the experiment was to study relationship between age cows, blood BHBA content, and CLA isomer (C18:2 cis9,trans11, CLA9; C18:2 trans10,cis12, CLA10) content during first three weeks post-partum. For experiment, 105 cows were selected from entire herd assigned one four groups: healthy primiparous (PH), multiparous (MH) or ketotic (PK), (MK) based on their symptoms, serum concentration...

Present study was conducted on 12 dry Surti buffaloes to assess the effect of heat stress amelioration during period their biological responses and milk production in subsequent lactation. Buffaloes were divided into control (n=6) treatment groups. Treatment housed only shed having wall-mounted fans, roof whitewashed with microfine lime powder open paddock covered 75% green net. At -8, -3, +1 +...

Minerals and some biochemical parameters determined from blood serum analyses in left displacement abomasum (LDA) affected and healthy dairy cows to evaluate the effect of displacement abomasum on mineral status, energy metabolism and liver function. Samples were collected from 60 affected cows and 60 healthy control cows matched with cases, based on herd, parity, and stage of lactation. Concen...

The metabolic adaptation of dairy cows during the transition period has been studied intensively in the last decades. However, until now, only few studies have paid attention to the genetic aspects of this process. Here, we present the results of a gene-based mapping and pathway analysis with the measurements of three key metabolites, (1) non-esterified fatty acids (NEFA), (2) beta-hydroxybutyr...

Metabolism in the mammary gland was related to changes in milk output in response to changes in dietary protein intake. Three diets of grass silage and concentrate were fed to four lactating dairy cows equipped with intravascular catheters across the mammary gland. Concentrates differed in the inclusion of protected soybean meal and provided 11.3, 15.4, and 20.1% CP, respectively. Blood samples...

Twenty-four Holstein dairy cows were used to evaluate the single and combined effects of different levels of crude protein (CP) and monensin treatment during early lactation on blood metabolites, milk yield and digestion of dairy cows. The experiment was designed as a completely randomized block with a 3×2 factorial arrangement of treatments. The factors were three concentrations of CP suppleme...
