Effects of acclimatization on energy expenditure by meat goats

Effects of acclimatization on energy expenditure by different goat genotypes

“…EE:HR was generally greater and varied much more among times of measurement than observed by Patra et al (2009) with yearling Boer and Spanish doelings. Factors responsible for these differences between studies are unclear, although gender could be involved.…”

“…1). Apparently, barn conditions prevented animal exposure to high Ta relatively more than observed by Patra et al (2009). Figs.…”

“…The deviation of EE by each animal at a particular time from the average for that animal overall the entire year (EEdiff) was determined. Simple correlation coefficients were determined between average mean daily Ta, RH, and THI in the 2 and 4 wk preceding HR measurement and EE and EEdiff, based on stronger relationships between EEdiff and climatic measures at 2 and 4 wk than 6 and 8 wk noted by Patra et al (2009). The same procedures were employed with the full-day measurement of Ta, RH, and THI and day length in the month preceding determination of EEdiff.…”

“…A recent study (Patra et al, 2009) dealt with effects of acclimatization on energy requirements of two meat goat genotypes in the U.S. (i.e., Boer and Spanish).…”

Effects of restricted periods of feed access on feed intake, digestion, behaviour, heat energy, and performance of Alpine goats

“…The confinement facility, described by Patra et al (2009), had 5.57 × 3.06 m pens. An area of 5.57 × 1.33 m at the front of each pen had an elevated expanded metal floor, with a flush manure system used once daily.…”
