Article Synopsis
- - The study aimed to analyze how maintenance energy needs in limit-fed Angus cows relate to energy used for building maternal tissue and milk production, and how this retained energy impacts forage intake during the dry period.
- - Twenty-four Angus cows were monitored over a 79-day late lactation phase, with precise adjustments made to their daily feed intake based on changes in body weight, and milk production and composition were measured periodically.
- - Findings indicated that maintenance energy for lactation was lower than expected, suggesting that as cows retain more energy (gain less weight and produce more milk), their energy requirements for maintenance decrease, differing from earlier beliefs about the relationship between milk yield and maintenance needs.
The objective of this study was to examine the effects of diet energy density on ranking for dry matter intake (DMI), residual feed intake (RFI), and greenhouse gas emissions. Forty-two mature, gestating Angus cows (600 ± 69 kg body weight [BW]; body condition score [BCS] 5.3 ± 1.

This was a replicated 5 × 5 Latin square with five drinking water treatments within each square: 1) fresh water (Control); 2) brackish water (100 BRW treatment) with approximately 6,000 mg/kg total dissolved solids (TDS); 3) same TDS level as 100 BRW achieved by addition of NaCl to fresh water (100 SLW); 4) 50% brackish water and 50% fresh water to achieve approximately 3,000 mg/kg TDS (50 BRW); and 5) same TDS level as 50 BRW achieved by addition of NaCl to fresh water (50 SLW). Each of the five 21-d periods consisted of 14 d of adaptation and 5 d of data collection.
