“…Although energy may be a limiting factor, endogenous fat reserves may be used to bridge the gap between lactation requirements and actual diet quality. However, milk production may be more directly tied to current protein intake (Bahnak et al 1979), and low N intake by the dam reduces neonatal viability in deer (Sams et al 1995). We therefore selected a target diet quality of 14% CP, which is considered the minimum requirement to support a lactating female with one fawn (Verme and Ullrey 1984).…”

Deer Forage Response to Herbicide and Fire in Mid‐Rotation Pine Plantations

Mid‐rotation management practices for pine (Pinus spp.) plantations enrolled in cost‐share programs have not been widely evaluated for wildlife. Mid‐rotation pine plantations often have a substantial hardwood mid‐story that limits growth of desirable understory forage species important to white‐tailed deer (Odocoileus virginianus; deer). We treated with imazapyr herbicide and prescribed burning (HB) 11 thinned, 13–22‐year‐old loblolly pine (P. taeda) plantations in the Upper Coastal Plain (UCP; n = 5) and the Lower Coastal Plain (LCP; n = 6) of Mississippi, USA, enrolled in cost‐share programs. We then sampled these plantations for production of important deer forages during July of 2003 and 2004, years 1 and 2 posttreatment. Deer foraging habitat was clearly improved by the HB treatment in both regions by year 2. Forb species of annual importance to deer increased in percent cover and biomass in the UCP and in biomass in the LCP. We estimated nutritional carrying capacity using a target diet quality of 14% crude protein; estimates in HB plots were 3 times greater than controls in the UCP and 19 times greater in the LCP. Although UCP sites had baseline carrying capacities nearly 8 times greater than LCP sites, the greater relative response to HB in the LCP eliminated the regional difference. Our results indicate that imazapyr herbicide treatment followed by prescribed fire is a beneficial tool for deer management in mid‐rotation pine plantations.

“…Serum urea nitrogen concentration increased with increased level of protein in the diet. Several earlier reports (Bahnak et al, 1979;Brown et al, 1995;Putto et al, 1998) indicated that SUN was sensitive to change in dietary protein. Thus, it seems that SUN can be used as an indicator of diet quality in blackbuck.…”

A feeding trial was conducted to determine the optimum level of crude protein (CP) in the diet of captive blackbuck (Antelope cervicapra) in which feed consumption and nutrient utilization are maximal. Fifteen blackbucks (BW 25-34 kg) were distributed into three groups of five each in an experiment of 75-days duration including a digestion trial of 5-day collection period. All the animals were offered 200 g of concentrates and fresh maize fodder ad libitum. The overall CP content of the three respective diets was 6.9%, 10.4% and 12.7%. Blood samples were collected on the last day of the experiment. Intake and digestibility of CP increased (p < 0.01) with the increased level of CP in the diet. Feed consumption and nutrient intake were not significantly different among the groups. However, digestibilities of most of the nutrients were higher in the 10.4% CP diet than in the 6.9% CP diet. The endogenous loss of nitrogen was similar among the groups. Based on the endogenous losses, minimum N requirement was calculated to be 776 mg/kg BW(0.75) /day, and to meet this requirement, diet must contain at least 8.27% CP. Serum urea nitrogen concentration increased (p < 0.01) with increased level of dietary CP. Serum level of glutamate oxaloacetate transaminase and glutamate pyruvate transaminase was higher (p < 0.05) in the group fed 6.9% CP diet. Animals in the group fed low protein diet also lost body mass during the experimental period. It was concluded that a diet containing 10.4% CP was optimum for maximizing nutrient utilization without any adverse effect on voluntary feed consumption and serum metabolite profile of blackbucks.
