In dairy cows the peripartum period involves endocrine and metabolic changes to compensate for the increased energy requirement aggravated by reduced feed intake. Cows adjust to the resulting negative energy balance with the mobilization of lipids from adipose tissue that, if excessive, could lead to many transition disorders compromising the offspring’s growth and well-being. The aim of this s...

Data from six experiments (two with dry cows) were used to predict partitioning of gross energy to CH4 in Holstein cows using selected independent variables, some of which were intercorrelated, and a stepwise backward elimination regression procedure. Methane outputs ranged from 3.1 to 8.3% (mean 5.5) of gross energy intake for 134 dry cow balance trials and from 1.7 to 14.9% (mean 5.2) of gros...

Increased energy demands to support lactation, coupled with lowered feed intake capacity results in negative energy balance (NEB) and is typically characterized by extensive mobilization of body energy reserves in the early postpartum dairy cow. The catabolism of stored lipid leads to an increase in the systemic concentrations of nonesterified fatty acids (NEFA) and beta-hydroxy butyrate (BHB)....

Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

the base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...

Variables derived from milk yield records were investigated to find an easy to measure and readily available indicator of the energy balance status of a lactating cow. Weekly energy balances during the first 180 d in milk (DIM) were calculated from weekly yield, live weight, and energy intake records for 470 first lactation heifers. The energy balance curve for each cow was estimated using a ra...
