steer vs heifer weight gain
Animals and hence their carcass types are classified as: Bull - entire cattle with masculine characteristics; Steer - male cattle castrated when young. “This is a great definition. Fetal growth is rapid. The SDSU Extension Beef Cattle Budgets can be used to estimate revenues and costs associated with six different beef cattle enterprises: Heifer development, Cow costs, Backgrounding from November to February, Finishing Steers, Backgrounding Yearlings from 750-1100 pounds, and Finishing Yearlings from 1100-1400 pounds. The calf-fed diet is meant to “get them ready for the feedlot setting,” Cassie Youst, Penn State Extension Dairy Educator said. However, feed efficiency favored the heavier test weight barley. 3.2 % of body weight: Daily rate of gain: 2.2 lbs. Beef steers gained more weight per day in only 6 of the 13 trials. Cattle Prices - Cattle market reports. Steer A vs. steer calves with an average weaning weight of 500 lbs. example, a 400 kg steer weighed ‘full’, i.e. Steers fed the light test weight barley required 4% more feed per unit gain than those fed medium or heavy barleys, but the difference was not significant. By contrast, a 16-month old steer with a hip height … In some cases, steers fed to higher weights (even above 1,100 pounds) may be more profitable. The weight is lost in 2 ways. Heifers receiving either a Ralgro or Synovex-C implant gained more weight … Faster-gaining steers had heavier harvest and carcass weights, and higher yield and quality grades. Steer and Heifer … steers (529 vs. 559 lb, weighted average) and finished at heavier final weights (1003 vs. 925 lb). (This weight allows for reduced weight gain and shrink because of training, fitting, conditioning and hauling.) Based on iterative optimization to minimize the difference between expected and observed DMI, revised equations for retained energy (RE, Mcal/kg) were developed for steers and for heifers: RE steer = 0.0606 × (LW × 478/MFW steer) 0.75 ADG 0.905; RE heifer = 0.0618 × (LW × 478/MFW heifer) 0.75 ADG 0.905, where LW = mean shrunk live weight. Graze them on pasture for grass fed cattle or supplement their diets with grain or protein feed for more rapid weight gain. gain per day * *(Average Daily Gain for the entire feeding period) A nutritional program can now be designed to provide a ration that will provide 2.0 lb. Numerous research trials have shown that implanted steer calves gain at a rate equal to, or greater than, bull calves. Average daily gain was similar between H-HEIFER, L-HEIFER and STEER and lowest in COW (P<0.01). The eating quality of roast m. longissimus dorsi, casseroled m. supraspinatus, minced m. gastrocnemius and grilled m. psoas major from bull beef, slaughtered at 400 days was different (by triangular tests) from that of twin steer beef. It is not uncommon for the buyer of a live animal to question, “The dressing percentage of my 1400-pound steer was 63% but I only got 550 pounds of meat – where is the rest of my meat?” The calculation of dressing percentage is based on hot carcass weight. So you only need to use one applicator and one implant for all your cattle — providing labor savings and improved … ; illustrates the body weight change throughout the feeding period. With beef breeds, many steers go into the feedlot at 500 to 850 lb and reach their finished weight at 1200 to 1400 lb. throughout the developmental period. variations in oats. Total fresh feed consumption for 100 days: Final weights are adjusted to a common age at slaughter. Break-even purchase prices. 2 lbs. The prices used for 550-pound and 750-pound steer calves were from USDA cattle market data summarized and reported for Nebraska and posted October 2, 2015. Generally, 100% grass-fed cattle are harvested at 1,000 to 1,200 pounds live weight, yielding a 550 to 600 pounds hot carcass weight (hanging weight). Farmers must maintain a high weight-gain rate for the animals, and meet strict quality targets. Suckling calves: Implanting suckling calves once with zeranol or estradiolprogesterone type implants will increase daily weight gains an average of 0.10 pound per day for steer calves and 0.12 pound per day for heifer calves (Selk, 1997). illustrate weight change during the first week of weaning (Table 1). Dairy steers are an important part of the U.S. beef supply. The higher yielding animal is worth an extra $0.92 per cwt on a live weight basis. For instance, heavy steers destined for the Japanese short fed market have an entry weight of approximately 450kg and a finished weight of 600kg, giving an average weight of 525kg. Therefore,castrating and implantingcan add value byincreasing market weight while avoiding the cost ofdiscounts for intact males. As soon as the dollars catch up to the gain, the added value that is represented by 2.80 pounds per day gain on grass versus 4.07 pounds per day gain in the feedlot can be assessed. They are the only true 200-day trenbolone acetate and estradiol implants for use in both steers and heifers. It is not clear at this tirae if the weight—gain advantage is due to bull vs steer calves, or breed effects. MGA® may be combined with Rumensin or Bovatec in supplements or rations offered to heifers. Calves of this age and weight should have fully developed rumens and be able to fully utilize forage based rations. For example, a 0.5% difference in the dressing percentage between steer A and B shown in Table 1, results in a $12.02 difference in price per animal. Another good rule of thumb is to aim for an 1,100-pound finishing weight, but this varies depending on breed. For a backyard steer, 90 days on grain should be sufficient. It will take 66 days to get there and the sale date will be April 19. 1. Gilts usually require less feed per lb. A summary of several research studies revealed that implanting steer calves only once improved daily gains by 0.10 pounds per day, and implanting twice increased daily gains by 0.13 pounds per day when compared to calves receiving no implants. Data collected by Superior Livestock from 2011 to 2013 shows the premium was only $1.13/cwt for non-hormone treated calves — not statistically different than the price received for implanted calves. This weighted difference of 98 pounds more feed and $1.62 higher feed cost per hundredweight gain cannot be explained by differences in gain in the feedlot or entirely by maintenance re- Heifers can gain from 0.40 to 0.46 lbs per day less than steers (Williams, 2002, p.2). Feeder steer (Long Fed) Purebred Angus steers (no scurs, no white colour forward of navel) weighing 400-500kg with 0-2 teeth and no HGP, preferably vendor bred, are grain fed for up 270-300 days and slaughtered at carcase weights of 420-470kg, averaging 440kg. From the side, the ideal steer should be free of extra leather in the throat area and have a clean, neat brisket and dewlap. In 1996, steers' and heifers' average daily weight gain was quite different; information from table 2 can be used to find the correct price to charge for the heifers. Once a heifer has a calf, she automatically becomes a cow. During the first week post-weaning, the average for HHAB steer and heifer weight changes was -5.15, -1.58, and -0.91 lbs/da, respectively, for calves previously stocked at low, medium, and high rates (Table 1). processor. Cows need to gain 1 to 1.25 lbs per day, while heifers and young cows need to gain 2 to 2.5 lbs per day. 0777 – Bull & Heifer Developer Pellets Read more; 0762 – 12% Pelleted All Stock Read more; 0763 – 14% Pelleted All Stock Read more; 7118 – 12% NP Hi-Fat Pellets Read more; 0776 – Bull & Heifer Developer (Medicated) Read more; 1; 2; 3 → gain / 150 days = 2.0 lb. Animal #1 Animal #2 Animal #3 Animal #4 Steer/Heifer’s Name: Steer/Heifer’s Ear Tag or At the one-quarter of 1 percent body weight supplementation rate as well as the one-half of 1 percent body weight rate, cattle gained about 2.22 pounds per day. Hereford bulls had the lowest average daily gain on test (3.18 Ib per day) but were bunk-line fed the lowest energy diet. This also means that heifers do not convert the feed as well as steers. Feed costs, genetics, flesh condition, weather and especially health of the cattle is critical in achieving an efficient cost of gain. An extra pound of gain took 7.4 pounds of supplement. Steer vs Heifer Feedlot Days On Feed P<0.0001 a b Savell 2008 . However, there is usually a dramatic decrease in daily gain and feed efficiency for Holstein steers weighing greater than 1,100-1,150 pounds. Steer calves fed for 60 days had an average buy/sell margin of $14.15/cwt and a . Finishing management. Steer … The carcass weight is usually between 600 and 900 pounds. Weight Gain in Beef Cattle Production . Holsteins consumed 3.7% more DM per day (18.39 vs 17.71lb/d) than the beef steers. per day on average. The Angus group averaged 1,214 lb., while their next closest counterparts, the other breeds, left the feedyard at 1,189 lb. Summary Mixed small and medium-frame Angus steer and heifer calves (n = 207) were used in a three-year Gain birth to weaning 1.0 kg/d Gain from weaning to mating 0.7kg/d Gain from mating to post calving 0.7 kg/d (includes calf weight in utero) Gain calving to end of bulling 0.3kg/d Gain 30kg in the year. Ralgro®, Synovex®, Compudose® or Steer-oid® implants will increase the rate and efficiency of gain of 400-pound-plus calves, especially if the calves are gaining over 1 pound daily. straight off feed, might produce a carcase weighing 208 kg. Again, if you can add weight gain for less than $0.90, you would sell the 700-pound feeder steer. Kansas studies showed an increase in average daily gain per steer of 0.35 pounds from late summer supplements of one to two pounds of feed per animal for steers grazing range grasses. Another method is to allow them to gain at a slow rate early in the developmental period (~1 lb. Average daily gain (3.62 lbs./day) was similar among steers grading USDA Prime, Choice and Select but was lower in steers grading Standard or below (3.30 lbs./day). of gain than barrows but more protein (Table 2.). Step 3. Therefore, 3.7% shrink factor. Steer calves and most heifer calves are sold, but some may be selected to enter the breeding herd. Yearling Bulls vs. Steers Yearling Bull Steers Live weight @ slaughter (kg) 636 630 Daily LWG (kg/d 1.50 0.84 Feed DM consumed 1890 4230 Cold Carcass Wt (CCW) 350 kg 340 kg Age - months 13 23 Age -days 395 699 KO % 55% 54% Feed cost £312 £423 Other Var. Journal of Animal Science, 2008. weight. Heifers need to eat 0.35 to 0.50 lbs more feed than steers to create a pound of meat (Williams, 2002, p. 2). It is one of Queensland's leading industries and a major source of export income for the state. Grazing steers at 425 pounds and greater weight decreases the cost of gain as compared to rations with stored feed. Moving forward we plan to sell the steer calves between 250 and 350 pounds, as it seems the return on investment diminishes quickly after that point. crease daily weight gains an average of 0.10 pound per day for steer calves and 0.12 pound per day for heifer calves (Selk, 1997). Break-even prices when fat steer and heifer prices are the same per cwt. Performance, DMI, diet composition, and slaughter data from 9,683 pens of steers and 5,009 pens of heifers that were fed high-concentrate diets for 90 d or more were obtained from 15 feedlots from the western United States and Canada. Break-even purchase prices. 1981 Animal Science Research Report 17 Table 2. Cattle are sold at the end of this phase when they’re around 10-14 months old and weight 700-900 lbs. 3 things to look at. represents the average steer or heifer; ... observed weight gain or possibly by feed intake during the first 30 to 60 d in the feedlot (Strasia 359 . She’s on 10 lbs of steer grower at 12% protein each day, 4 lbs of precon, 4 oz of show bloom, 2 oz of corn oil, and 5 grams of probiotic. For the miniature steer at that same point the weight is about 350 - 500#. Total steer and heifer slaughter in 2012 (25.43 million head) was less than 2019 (26.1 million head) and fractionally higher than 2020 (25.3 million head). Buyers try to purchase even lines of calves with good weights. … A pasture-based diet will burn energy, decreasing the gain received from grain. Estimate the stock growth rate and weight gain (kg/head/day) Example for estimating growth in 300kg growing steers or unjoined heifers in 100 days grazing. The transition between a ranch and feedlot is a challenging time for cattle, as they are exposed to multiple stressors including handling, transpor-tation, commingling, in addition to changes in feed, MGA® is a hormone material added to the ration of feedlot heifers. 425# steer@$202 = $858 525# steer @$182 = $955 On a moderate framed one, that takes time. Calves are sold at weaning (typically 205 days of age) or are retained for an additional forage production season as stockers. Although breeds with full-sized carcasses will likely continue to dominate the general U.S. meat market for some time, the Lowline Angus breed may continue to find its niche with small- acreage owners, producers, and 4-H members alike. The data set included pen means for more than 3.1 million cattle … Implants can improve rate of gain by as much as 0.25 pounds daily in a winter period. The US beef industry is focused mostly on … Based on a ration cost of $187/tonne* (or 0.085 cents per pound), Steer A costs $1.79 to feed per day. Buyers try to purchase even lines of calves with good weights. Selling weight: 940 lbs. These farms achieved average of mob liveweights of >540 kg at 16 months of age. For increased rate of weight gain in steers fed in confinement for slaughter, and for increased rate of weight gain and improved feed efficiency in heifers fed in confinement for slaughter. (880 hot carcass weight ÷ 1400-pound live weight) x 100 = 63%. Recent Online Sale Reports. Rate of gain was improved 10.3 percent and feed efficiency 6.5 percent in an average of 47 trials. “That is within reason of what we would expect a stocker calf of that age and that size to gain,” Rouquette said. Steer B Table 1 follows Steer A and Steer B through a typical finishing phase. Dressing % = (208 ÷ 400) × 100 = 52% If the same steer had been held off feed overnight, he could have lost about 5% of his liveweight in gutfill, and weigh only 380 kg next day after the overnight curfew. Queensland is the largest grower of beef cattle in Australia. At 16 months this same steer will have a hip height of 49.6 inches, but its frame score (4) and target slaughter weight (1100 lbs) will still be the same. The extent that forages contribute to a ration is determined by the price of feed grains or food processing by-products with equivalent feed value. 33 Relationship of fat percentage to days on feed . The ideal market steer (Figure 7) should be a stout, fast growing animal that is heavy muscled and carries a minimum amount of outside fat. Carcass weight is relevant only for payment purposes. After weaning from its mother, a stocker is put on grass or some other type of forage to promote growth and weight gain. That rapid rate of gain on summer grass … Really, non breeding stock heifer should be listed as well.
