The lack of adaptation leads to poor performance of bulls both physically and during the breeding season. The most accurate and proven way of doing this for the last point is paying close attention to Estimated Breeding Values (EBVs). The uses of organic minerals that may result in the greatest benefit include zinc, selenium, and copper. Limited land resources are increasingly putting pressure on beef cattle producers to optimize and even maximize production on a given land resource. In addition, trace mineral requirements should be met. Whether they are young, first-season bulls or older, more experienced bulls, condition is key to maximizing their performance. A bull needs to be athletic, not fat. A maximum of 45 to 60 days is an ideal length of breeding season for yearling bulls. When growing bulls, its important that the ration is geared toward longevity and soundness as well as growth and gain. Boyles, S. Bull nutrition and management. Following are nutritional factors to consider when developing bulls post-weaning to the yearling stage. The notion that dairy cows must give birth to produce milk and that the calves are immediately separated from the dam, many of which will end up immediately being sold as surplus calves, has become a topic of public concern. By the time we wean them theres green grass coming and we just turn them out and let them grow, says Ehlke. In our program, we want to give young bulls every chance to exhibit their performance, but at the same time keep them sound and not too fat. Many diet formulations can easily satisfy yearling bull maintenance and growth requirements. Saughland Farm - High genetic merit rams enhance carcase value. https://edis.ifas.ufl.edu/AN211. This not only allows time to replace bulls if necessary, but also minimizes the time between examination and start of breeding. All bulls should be gaining weight and some condition during this period. Breeding soundness exam research has reported that bull with scores greater than 71 have a dramatically higher conception rate than those scoring 70 or less points. Selection: The breeding bulls should be selected from good pedigree Feeding: The properly balanced ration should be given which contains adequate energy, protein, minerals & vitamins.

Feed and management of these young bulls is very important, however, to ensure that they can stay sound and fertile. The Auburn Soil, Forage, and Water Testing Laboratory offers both forage and feed analysis services that can help producers understand the relative energy and protein value of feed resources. A variety of roughage sources are acceptable as ingredients for bull rations. (1998) determined that feeding 31 mg of free gossypol/ lb of bodyweight/ day (6 to 14 lbs of WCS) to growing bulls from 6 to 16 months of age resulted in increased sperm abnormalities, decreased sperm production, and adversely affected measured aspects of bull sexual behavior. The bull needs all that physical fitness as he will spend a significant amount of time following cows rather than feeding over the course of the breeding season. One of the most common complaints of yearling bull purchasers is the run down condition these bulls can exhibit after their first breeding season. As a result of this decision, producers need to consider utilizing bulls that will produce calves that will meet industry carcass standards. Regardless of the choice to include organic sources, the use of a well-balanced mineral and vitamin supplement to meet the bull's requirements is the main management consideration. Critical evaluation of all nutritional supplements should be based on the amount of nutrients supplied, the cost to supply the nutrients, and the acceptability of the supplement for the total nutritional program. Arthington, J. D., K. R. Johnson, L. R. Corah, C. L. Williams, D. A. Hill. The feed industry, popular press, and other cattlemen often offer conflicting advice about feedstuffs or their ingredients. Feeding too much grain to finishing cattle too rapidly can lead to lactic acidosis or founder ( see Subacute Ruminal Acidosis in Cattle and Sheep Subacute Ruminal Acidosis in Cattle and Sheep Subacute ruminal acidosis is characterized by intermittent, self-correcting periods of low ruminal pH. Extension Beef Specialist A good recovery period is essential for bulls to be fit and ready for next year's breeding season. There is no single best feedstuff that will grow, develop, or maintain bulls. o [ canine influenza] Breed type is an important consideration for the bull and the resulting mating with the cow herd. From an early age the bull should learn to associate people with feeding, grooming or exercise. A structurally sound, yearling bull should not require any foot care. PDF Concentrate Feeds - Teagasc Fall calving has become more prevalent, particularly in the south. In addition to gaining back this weight during their first rest, they must also gain enouch body mass as to achieve 75% of their mature weight by their second birthday. Then through winter they are fed at a neighbors feedlot, who raises registered Red Angus. This paper will start with nutrition. After the first breeding season, bulls may need to regain several hundred pounds of body weight depending on condition losses. Service capacity is the number of cows a bull can adequately detect in estrus and potentially breed during the defined breeding season. Overfeeding should be avoided for several reasons. 1. The effect of dietary zinc level and source on yearling bull growth and fertility. UF/IFAS EDIS document. The level of exposure will be dictated by the level of WCS supplementation and potential level of gossypol consumed by the bulls. Bulls should be drenched to prevent introducing worms and, if necessary, should be treated for lice. Whether the bulls were developed on the ranch, in a commercial facility, or at a centralized bull test, they were probably fed to gain from 2.5 to 4.0 pounds per day from weaning to one year of age. When to Cull Bulls - Livestock Expected Progeny Differences (EPD) predicts the differences expected in performance of future progeny of two or more sires of the same breed when mated to animals of the same genetic potential. As bulls increase in body weight, they require a greater amount of daily dry matter intake to meet the same production goal. Spring-born calves commonly are weaned at 67 mo, and their dams bred back while on pasture. When feeding more mature bulls, the use of WCS may be an acceptable feedstuff for the majority of the year.
