Book Description
Cattle consuming low-protein forage (7% CP) require additional supplemental protein to maintain BW and BCS. Daily delivery of protein supplements places undue financial burden on cattle producers. Supplementing cows as infrequently as once every 6 d) has resulted in similar changes cow BW and BCS when compared to daily supplementation. As calving season nears, producers may wish to increase supplementation frequency. The responses to a change in supplementation frequency during the third trimester of gestation have not been widely investigated. Therefore, our objective in Study 1 was to evaluate the effect of altering supplementation frequency during late gestation on performance of spring-calving cows grazing low-quality, dormant native range and supplemented with dried distillers grains with solubles (DDG). Angus x cows (n = 238; mean age = 6 ± 2.5 yr; average initial BW = 618 ± 56.2 kg; average initial BCS = 5.7 ± 0.03) were stratified by age, BW, BCS, and assigned randomly to 1 of 4 treatments: 1) DDG daily (D1); 2) DDG once every 6 d (D6); 3) DDG daily from d 1 to d 60 and then every 6 d (D1-D6); 4) DDG every 6 d from d 1 to d 60 and then daily (D6-D1). Treatments were initiated 100 d prior to expected onset of calving. Cow BW and BCS were measured every 28 d. Cows were sorted daily before supplementation at 0830 h. Supplement delivery was calculated to meet dietary CP requirements. Increasing supplementation frequency 28 d prepartum negatively affected final BW and BW change from d 61-88 for the D6-D1 supplementation group (P 0.05) compared to other supplementation groups. Cow BW change for the study (d 1-88) was also less (P

Book Description
In many pasture and rangeland scenarios, low-quality forages (6-8% CP) are the primary energy source for some portion of the year. At these times, energy is typically the first limiting nutrient to the ruminant. Low-quality forages are generally not limited in availability; however, the high cell wall content and reduced levels of CP prevent ruminants from being able to extract the harvested energy. Without provision of supplemental nutrients, the available energy may be inadequate to meet performance expectations. Protein supplementation during periods of inadequate forage quality has been observed to alleviate ruminal nitrogen deficiencies and increase forage utilization. Increased forage utilization translates into greater energy extraction allowing for increased animal performance. The first trial was conducted to evaluate the effects of utilizing non-protein nitrogen (a slow-release urea compared to urea) on intake and digestion of beef steers consuming low-quality bermudagrass hay. Steers were provided ad libitum access to a low-quality bermudagrass hay (7.3 % CP and were ruminally dosed once daily with either urea or slow-release urea (SRU) at levels to provide 0, 64, 128, or 192 mg of N/kg of initial BW per day. Additionally, steers were supplemented with glycerol at levels of 0 or 0.1% of initial BW per day. Total OMI and forage OMI (FOMI) increased quadratically (P

Book Description
Documents the effects of adopting standards for public land health and guidelines for livestock grazing management on Bureau of Land Management (BLM) administered land in New Mexico. The standards and guidelines would be incorporated into eight BLM resources management plans (RMP) that cover approximately 13.5 million acres. In addition, for each alternative there are existing land use decisions that are in conformance with the standards. These decisions would be changed to bring them into conformance"--Page xiii.

Book Description
Two experiments evaluated the effects of altering dietary protein on beef cattle performance and nutrient excretion. In the first study, concurrent experiments were conducted to evaluate the effect of protein supplementation to beef cattle grazing warm-season shortgrass forage during the late growing season. For all Exp., treatments consisted of a supplemented group (1.32 kg of a 39% CP fed 3 times a week) and a non-supplemented control group. In Exp. 1, cow final BW (P = 0.24) and ADG (P = 0.38) were not affected by treatment. There was no difference (P = 0.97) in cow final BCS regardless of treatment. Calf ADG (P = 0.54) and weaning weight (P = 0.45) were not affected by treatment. In Exp. 2, cow final BW (P = 0.39) and final BCS (P = 0.81) did not differ between treatments. Cow ADG (P = 0.07) tended to be greater when supplemented with 0.22 kg CP per day. Calf ADG (P = 0.50) and weaning weight (P = 0.11) did not differ between treatments. In Exp. 3, heifer final BW (P = 0.17) was not different between treatments. Heifer ADG (P = 0.02) was greater for supplemented heifers. Supplementing protein to cattle grazing late season medium quality forage is advantageous for increasing ADG in replacement heifers and potentially beneficial to improve condition in lactating primiparous cows. In a separate study, a commercially available condensed tannin (CT) extract (ByPro; Silva Team, Ontario, CA) was included in a cereal grain-based diet at 3 levels (0, 1, or 2% of diet, DM basis). No group by treatment interactions was detected (P ≥ 0.18) among the response variables. Provision of CT did not affect (P ≥ 0.64) DM intake or apparent total-tract DM digestion. Nitrogen intake was not affected (P = 0.58) by inclusion of CT in the diet, but fecal N output increased (P = 0.04) at 2% CT inclusion compared with control. However, there was no difference (P = 0.36) in urine N output among treatments. Nitrogen retention was less than (P = 0.03) with 2% CT than 0 or 1% CT. Proportion of total N excreted in urine decreased (P = 0.03) with CT supplementation at 1 or 2% in the diet. Similarly the proportion of total N excreted in feces increased (P = 0.03) with 1 or 2% CT inclusion. Site of N excretion was shifted away from urine and toward feces when CT was included in a complete diet fed to beef cattle.
