In most areas of Michigan deer have overbrowsed cedar swamps, one of their favorite food sources in the winter, to the point where there’s no food left for them, he said. It’s important to recognize that some bucks might have larger antlers than others at yearling age for many various reasons, such as being born early, being a single fawn raised by a maternally experienced doe, being disease free, or having been raised in exceptionally good habitat. Personally, I don’t know if the research reported by Hewitt and his group will put an end to the yearling buck culling debate. The intended purpose is often to improve antler quality in the population. Some researchers have openly criticized the study by Koerth and Kroll, claiming methodology and data analy- sis were flawed and biased conclusions. They cost $2.60 a pound. RELATED: Council rejects deer cull request. Among whitetails, the culling harvest strategy generally involves targeting those bucks with inferior antlers for removal to improve overall antler quality of those left to do the breeding and for harvest at an older age. to reduce the number of people that work for a particular company by a large amount: The programme of redundancies was intended to cull 1000 jobs. Free e-mail watchdog. The latest round of aerial deer culls in Victoria's Alpine region has sparked concern that the practice could be creating a "smorgasbord" of fresh food to support the region's wild dog population. Therefore, given the 4-point harvest strategy, a large percent of the yearling cohorts could legally be harvested. I’ll reserve final judgment until I see a study of comparable proportions conducted on Northern whitetail range (which is highly unlikely in the near future), where fluctuating environmental pressures differ from those experienced on Southern range. For example, research conducted by Mitchell Lockwood and his cohorts from the Texas Parks and Wildlife Department, indicated selective breeding by superior-antlered yearling bucks improves subsequent yearling antler scores. These could be bucks that lack 1 or both brow tines, bucks that are 7 points or less and 2.5 years old or older, or 3.5 and 4.5 year old bucks that have 8 … Bucks that started out with 3 or less antler points remained smaller in all measured antler traits at 2.5 years of age and in most antler traits at 3.5 years of age. The Culling Debate Until recently, the culling debate has revolved primarily around studies using captive deer, held in unnaturally high densities and fed either high-quality or restricted diets. Answer this question. They found that the doe’s nurturing ability was far more important than genetics in determining the yearling buck’s antler points, spread, weight and beam length. When people cull animals, they kill them, especially the weaker…. Delve deeply in Deer symbolism and meaning to find out how this Animal Spirit Guide can illuminate, support, and guide you. Lockwood and his group concluded the following: “Our findings clearly indicate that under constant suboptimal environmental conditions, phenotypic change in antler quality can be realized with intensive selective harvest of yearling males.”. But this is a complex subject deserving far more discussion than allowed here.

Given their study findings, the authors concluded the following: “Because of a positive relationship between yearling and mature antler size, selective harvest of juvenile males can either increase or decrease the aver- age antler size of the cohort, depending upon harvest criteria.”. In animal breeding, it is the process of removing or segregating animals from a breeding stock based on specific trait. FireCel features a two-temperature hand warmer, with both 110- and 130-degree settings, which will provide steady heat for up to 3 hours. — Strickland, B. K., S. Demarais, L. E. Castle, J. W. Castle, J. W. Lipe, W. H. Lunceford, H. A. Jacobson, D. Frels, and K. V. Miller. Presumed benefits of such harvesting were based upon penned deer research. Since whitetails exhibit segregation of the adult sexes, this also implies that habitat designed to favor one sex might not necessarily favor the other. According to Hewitt and his cohorts: “Our data show clearly that yearling male deer with small antlers have, on average, smaller antlers at maturity.” In their view, “The correlation between yearling and mature antler size was unequivocal.”. In subsequent years, they attempted to recapture and examine as many of the marked animals as possible. 3. n. Something picked out from others, especially something rejected because of inferior quality. These early studies indicated that removal of spike-antlered yearling bucks not only improved antler quality, but also improved inherent genetic traits for large antlers. Culling is the selective removal of presumably inferior deer in order to improve the quality of the remaining population. Get a hand warmer, LED flashlight, and portable power supply all in one device with FireCel – a versatile and compact multi-purpose tool! More specifically, these researchers discovered that implementation of a 4-point minimum harvest rule resulted in a reduction in average antler size among 2.5- and 3.5-year-old bucks in subsequent years on certain areas. recent questions recent answers. Another pattern is steady (incremental) growth throughout the productive life of the animal. The latest findings by David Hewitt and a group of Texas A&M researchers might have finally answered this rather intriguing question: Do yearling antlers serve as a predictor of antler growth potential? And does it work? There is an important factor to keep in mind: A cull to one person is not a cull to another, whether it be related to whitetail bucks or something else. For livestock and wildlife, … After an overwhelming 10-1 vote by city council to cull the deer population (a process which began January 4 and could continue into March), protests have raged throughout the community, with one group – called Ann Arbor Residents for Public Safety – even filing a lawsuit in federal court in an attempt to stop the process. Use of SHC that protects young males with small antlers should be viewed as a temporary solution to chronic age- structure problems.”. The topic always spurs lively debate among a group of hunters, but which bucks are cull bucks and which ones are not? Biology and Management of White-tailed Deer. The Latest It also looks at indicators like crop damage and whether the deer are infiltrating cities and damaging landscaping, as they are in Manistee. This does not mean antler genetics are unimportant. Then, the researchers compared recaptured bucks in the two antler-point categories to determine differences in antler growth at 2.5 years, 3.5 years, 4.5 years and 5.5 or more years in age. See it here now …, EXPLORE OTHER MEDIA 360 PROPERTIES FOR OUTDOORS ENTHUSIASTS. They speculate that this could have occurred for two reasons: (1) inherent regional differences in soil fertility and (2) differences in the buck harvest intensity. But is culling necessary? Management Implications Built with a high-quality aluminum shell, this device is durable enough for outdoor use, as well as compact enough to easily fit in your hunting bag, pocket, or glove compartment. — Demarais, S., and B. K. Strickland. Among whitetails, the culling harvest strategy generally involves targeting those bucks with inferior antlers for removal to improve overall antler quality of those left to do the breeding and for harvest at an older age. Meanwhile, I agree with the Hewitt et al. “Antlers.” Pages 107-145 in D. G. Hewitt (Ed.). Those concerned with woodland and wild flowers argue for an all-out war, pointing to research from the University of East Anglia that mooted a mass cull of 50–60% of all deer in … What does deer cull mean?

Jacobson and Texas A&M geneticist Steven Lukefahr based their conclusions on the examination of 220 yearling bucks raised at research facilities in Mississippi. Those favoring culling claim spike-antlered young bucks are genetically inferior, will never attain quality antlers typical of fork-antlered yearlings even when mature, and will contribute to perpetuation of such undesirable traits. ... Longueuil set to cull urban deer population, meat to supply local food bank. In Mississippi, research led by Bronson Strickland found that protection of small-antlered young males — intended to more closely balance adult sex ratios — might inadvertently contribute to smaller than normal antlers in subsequent years in some areas. Koreth and Kroll theorize there are different antler growth patterns in white-tailed bucks. Griffith said the DNR doesn’t have an ideal number of deer for the area and instead focuses on trends like whether the populations of cedar, oak and maple trees are regenerating. According to the researchers, this could have resulted in “random” removal of yearlings and no decrease in cohort antler size in subsequent years. ‘A mass cull is the only known method of ensuring the disease does not spread.’ ‘A mass cull is the only way to make sure that all these sheep are killed.’ ‘The pre-emptive cull of healthy animals in Cumbria is not happening at the pace the government intended.’ In addition, they claim culling will help reduce deer density, thereby improv- ing herd nutrition, as well as remove small-antlered genes from the herd and improve future antler quality. Griffith understands the appeal of buck hunting and antler trophies but says that by keeping the population numbers down, “nicer antler deer can be produced.”.
