“…In trials with domestic sheep the maximum consumption values of 56-82 g dry weight/kg/day were 60-62% within the range of digestibilities (Baumgardt, 1970;Greenhalgh & Reid, 1973) with the voluntary intake decreasing with changes in digestibility of forage. A similar pattern is found in wapiti or red deer (Cervus elaphus) (Maloiy & Kay, 1971;Mould & Robbins, 1982), roe deer (Capreolus capreolus) (Drożdż & Osiecki, 1973;Perzanowski, 1978;Drożdż, 1979), and white-tailed deer (Odocoileus virginianus) (Ammann et al, 1973).…”

Dry matter intake (DMI), and dry matter digestibility (DMD) were determined for three diets, using three desert bighorn sheep, Ovis canadensis mexicana. Bighorn sheep were placed in individual cages and fed three diets: high and low quality alfalfa, and Bermuda grass (Cynodon dactylon).Mean DMI of high quality alfalfa, low-quality alfalfa, and Bermuda grass was 1,281.3, 1,512.0, and 1,084.0 g/animal/day, respectively, with corresponding DMD's of 68.5, 64.1, and 57.7°/o. Dry matter digestibility was improved with increased crude protein and cell solubles, and with decreased neutral detergent fiber and hemicellulose. Mean digestibility energies for the high quality alfalfa, low quality alfalfa, and Bermuda grass were 642.6, 626.6, and 412.3 kJ/kg BW°-75 /day, respectively.

“…Quality of forage depends on habitat conditions and weather, but forage quality naturally declines through the summer and autumn as plants mature and senesce (Campbell and Dotzenko 1975, White 1992, Van Soest 1994). Forage quality is especially important for growing fawns that have high metabolic rates and small, undeveloped rumens (Montgomery and Baumgardt 1965, Ammann et al 1973, Spalinger 1980, Wallmo 1981). Although fawns may nurse more to compensate for poor forage quality, poor forage quality may simultaneously reduce the quality and quantity of milk produced by their mothers (Loudon et al 1983, Beauchemin 1991, White 1992, Morand‐Fehr et al 2007).…”

Forage quality's influence on mule deer fawns

et al. 2011

In many mule deer (Odocoileus hemionus) populations, recruitment of fawns drives population dynamics. The quality of food available to females and their fawns in summer and autumn may play an important role in fawn recruitment. We examined direct links between digestible energy (DE) content of food and the DE intake of females on the nutrient concentration of milk and between the nursing behavior, DE intake, growth, and survival in captive mule deer fawns. We offered females and their fawns diets that simulated the natural decline in DE content of forage from mid‐summer to late autumn in many western landscapes. Fawns fed a higher DE diet weighed 14% more at the onset of winter, had fewer unsuccessful nursing attempts, consumed milk with more protein and energy, and had higher survival than fawns fed a low DE diet. Differences between fawn performances among treatments were greatest when diet quality began decreasing earlier in the summer. Because our results indicate that summer and autumn nutrition is likely to influence fawn recruitment, wildlife biologists should include metrics for summer precipitation and late autumn fawn mass in population models, and land managers should focus on methods for improving the nutritional carrying capacity of summer and early autumn habitats. © 2011 The Wildlife Society.

1998, In vitro digestibility of seasoiiiil forages used by wapiti and roe deer in northeastern China, -Ecography 21: 11 -17.Seasonal changes in in vitro dry matter digestibility (IVDMD) of five forage classes (browses, sedges, forbs. ferns and the bark of Vimus spp,) used by wapiti and roe deer were determined in relation to chemical composition, using the two-stage technique of in vitro trial with rumen inocula from one wapiti and one roe deer captured in winter. Wapiti and roe deer showed remarkable fluctuation in IVDMD among seasons and forage classes. IVDMD decreased from 43,8-64.3% in spring to 29,4-40.5% in winter for wapiti, and from 52.4-77,4% in spring to 25.9-36,5% in winter for roe deer. There was significant variation in IVDMD among species of browses for wapiti and roe deer. IVDMD ranged from 28.5% to 58.7% in twigs and from 39.8% to 58,2% in leaves for wapiti, and from 24.1% to 67.7% in twigs and from m.ifA, to li.TA in leaves for roe deer. Roe deer had higher IVDMD (40,0-71.7%) in both leaves and twigs of browses than wapiti (35.9-58.7%) during snow-free seasons, but IVDMD of twigs was lower for roc deer (25,9-36,5%) tban wapiti (29.4-38,4%) in winter. Significant multiple correlation was found between NDF and ADF, and IVDMD in sedges, forbs and ferns for both wapiti and roe deer, whereas only roe deer showed the significant multiple correlation for leaves of browses.H.
