Peanut, row crops, palm tree, trees, Florida farm. UF/IFAS Photo: Josh Wickham.Variety choice is a critical management decision in producing a peanut crop. Since several good peanut varieties are available, it is essential to know each variety?s attributes and how different varieties might fit into a farm plan. This 7-page fact sheet provides data conducted from trials in Florida at UF/IFAS research centers located in Gainesville (Citra), Marianna, and Jay from 2010?2013. Written by Barry Tillman, Mark Gomillion, Justin McKinney, and George Person, and published by the UF Department of Agronomy, May 2014.

Can Maternal Colostrum Be Replaced by Commercial Products for Feeding Newborn Calves?

dairy-calf-feeding Colostrum management and feeding are critical for calf health, calves? future productive life, and farm profitability. Current recommendations state that a calf needs to ingest at least 150?200 g of immunoglobulin G within two hours of birth, but when colostrum quality is poor or unavailable, colostrum replacer may be a suitable alternative. This 3-page fact sheet presents the results of a recent publication that evaluated the effects of feeding maternal colostrum, one dose of plasma-derived colostrum replacer, or one dose of colostrum-derived colostrum replacer on serum total protein, immunoglobulin G concentration, calf morbidity, calf mortality, and weight gain from birth to weaning. Written by Klibs N. Galvao, and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, May 2014.

What Is the Most Cost-Effective Breeding Program for Lactating Dairy Cows: Timed AI, Estrous Detection, or a Combination of Both?

dairy-cowAs any other business enterprise, the sustainability of a dairy farm is highly dependent on economics. Reproduction influences both milk production and number of replacement heifers available on a farm; therefore, reproductive efficiency becomes a key determinant of dairy cow profitability. Several parameters affect reproductive performance. This 4-page fact sheet presents information from recently published articles that looked at the economics of different reproductive programs for breeding dairy cows that use estrus detection only, timed AI only, or a combination of both. Written by Klibs N. Galvão, Gustavo M. Schuenemann, Eduardo S. Ribeiro, and Jose Eduardo P. Santos, and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, May 2014.

What Is the Most Cost-Effective Breeding Program for Breeding Heifers: Timed AI, Estrous Detection, or a Combination of Both?

Photo by Milt Putnam.As any other business enterprise, the sustainability of a dairy farm is highly dependent on economics. In order to obtain a profitable return on assets, there is a constant need to maximize outputs and, oftentimes, to minimize inputs. Reproduction influences both milk production and number of replacement heifers available on a farm; therefore, reproductive efficiency becomes a key determinant of dairy cow profitability. This 3-page fact sheet presents information from recently published work that looked at the economics of different reproductive programs for breeding heifers that use timed AI only, estrus detection only, or a combination of both.

Feeding dairy cows at the University of Florida's Dairy Research Unit in Hague, Florida. Bos taurus, dairy cattle, livestock, industry, DRU. UF/IFAS Photo: Tyler Jones.It is well established that early cyclicity results in increased pregnancy per artificial insemination and decreased time to pregnancy. But none of the previous studies has used synchronization programs such as the Presynch-Ovsynch as part of their reproductive management. This 2-page fact sheet presents the results of a recent paper that evaluated the effects of administration of GnRH at 17 ± 3 and 20 ± 3 DIM in Holstein dairy cows without a corpus luteum (CL) on induction of ovulation, uterine health, and reproductive outcomes. Written by Klibs N. Galvão, and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, July 2014.

Targeting ADG of Developing Replacement Heifers Using Age and Body Weight

North Florida beef cattle, pasture, field, calf. UF/IFAS Photo: Sally Lanigan.Heifer development continues to be one of the largest expenses to cow-calf operations, primarily due to cost of feed. Replacement heifers should be bred to calve at 24 months of age in order to maximize lifetime productivity of breeding females. Therefore, heifers should conceive at 15 months of age and achieve puberty at 13?14 months of age because heifers are infertile on the pubertal estrous cycle. This 4-page fact sheet was written by Phillip Lancaster and Cliff Lamb, and published by the UF Department of Animal Sciences, September 2014.

Pests and Fungal Organisms Identified on Olives (Olea europaea) in Florida

Figure 1. Leaffooted bug, Leptoglossus phyllopus, on an olive tree in Marion County, Florida.Olive production in Florida has increased over the last few years. As trees become available in nurseries many homeowners are planting them in their landscapes. Fortunately, olives are a relatively pest-free species, but some occasional invaders can be a nuisance or cause lasting harm. A few plant pathogens that may infect olives also can lead to a decline in overall plant health, fruit yield, or the visual appearance of plants. Following correct cultural practices when growing olives can reduce your chances of tree loss from pests and diseases. A survey of olive production and interviews with Florida growers in 2014 identified the pests and diseases described in this 5-page fact sheet, written by Jennifer L. Gillett-Kaufman, Sandra A. Allan, Jonael H. Bosques-Mendez, and Lyle J. Buss, and published by the UF Department of Entomology and Nematology, September 2014.

When Should We Stop Breeding Dairy Cows?

vm200The decision of when to start and when to stop breeding cows during a lactation is often a challenging one for dairy producers. This 3-page fact sheet presents practical rules on how to determine when to stop breeding Holstein dairy cows based on persistency of milk production and break-even point for milk production.

Should You Breed Cows during the Summer in the Southeastern United States? An Economic Analysis of a Dairy Herd in Florida

dairy-cowIn the southeast United States, since dairy cows experience decreased reproductive performance during the hot and humid summers, some dairy farmers delay breeding until the cooler fall. But there is no economic data to support this practice. This 3-page fact sheet presents the results of a recent paper that evaluated the effects that delaying breeding during the summer has on cow performance and profitability in Florida. Written by Klibs N. Galvão and Albert De Vries, and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, July 2014.

Closing Your Seasonal Home

Figure 1.  Before leaving your seasonal home, perishable items should be eaten, given away, or discarded. Get organized and make a plan before you lock your doors to leave your home for an extended period of time. Proper preparation inside and out will help ensure your return to a clean, undamaged home. Florida’s environment creates the possibility for mildew growth, storm damage, and pests. Unoccupied homes are more susceptible to these types of damage. This 6-page fact sheet provides the necessary steps to prepare your home before leaving for an extended period of time. There is also a checklist to help you remember. Written by Julie England, Audrey Norman, Randall A. Cantrell, and Maria J. Portelos-Rometo, and published by the UF Department of Family Youth and Community Sciences, June 2014.

Elder Nutrition

Figure 1. By 2050 in the United States, the over-65 popluation will more than double and the over-85 population will quadruple. Good nutrition is important throughout life, starting even before we are born. However, at certain stages in life, such as infancy, pregnancy, and in older age, the importance of having good eating habits is especially critical. This 8-page fact sheet focuses on how aging affects nutrition and diet and choices that older adults can make to improve or maintain their health and well-being as they age.was written by Linda B. Bobroff and Martie Gillen, and published by the UF Department of Family Youth and Community Sciences, April 2014.
