Abstract This study evaluated the effects of timing of dried distillers grains (DDG) supplementation during late-gestation on performance of Bos indicus-influenced cow-calf pairs. At about 84 d before calving (d 0), 84 mature Brangus cows were stratified by BW and BCS (422 ±42 kg; BCS = 5.0 ± 0.14) and assigned randomly to bahiagrass pastures (14 cows/pasture). Treatments were assigned randomly to pastures (2 pastures/treatment) and consisted of no prepartum supplementation (CON), 1 kg/d of DDG from d 0 to 84 (LATE84; 84 kg of DM/cow); or 2 kg/d of DDG from d 0 to 42 (LATE42; 84 kg of DM/cow). The respective weekly supplement amount was divided and offered into 3 feeding events (Monday, Wednesday, and Friday). Cow BCS were assessed on d 0, 45, 84 (calving), 140 and 224 (start and end of breeding season, respectively). Calf BW was collected at birth and weaning (d 346). Growth and reproductive data were analyzed using SAS MIXED and GLIMMIX procedures, respectively. Cow BCS from d 45 to 224 did not differ between LATE84 and LATE42 cows (P ≥ 0.20) but was always the least (P ≤ 0.05) for CON cows. Calving date, calf birth BW, and percentage of pregnant cows on d 283 did not differ (P ≥ 0.19) among treatments. Calf pre-weaning ADG and BW at weaning did not differ (P ≥ 0.58) between LATE42 and CON calves, but LATE84 calves tended to have the greatest pre-weaning ADG (P = 0.10; 0.88, 0.83, and 0.82 ± 0.02 kg/d, respectively) and BW at weaning (P = 0.10; 263, 254, and 252 ± 4.4 kg, respectively). Therefore, timing of prepartum DDG supplementation did not impact cow reproductive performance. However, calf pre-weaning growth tended to be enhanced when cows received longer vs. shorter or no periods of prepartum DDG supplementation

The Impact

Abstract The beef cattle industry in the Southeastern United States relies primarily on forages that not always meet the cowherd nutritional requirements, resulting in reduced performance if supplemental nutrients are not provided. Although precalving nutrition modulates postnatal offspring performance, most studies did not utilize Bos indicus-influenced cows consuming low-quality, warm-season forages. Hence, 3 studies evaluated the impact of different supplementation strategies during gestation on subsequent cow and calf performance.Study 1focused on timing of dried distillers grains (DDG) supplementation during late-gestation. Treatments initiated 84 d before calving and consisted of no supplementation, 1 kg/d of DDG from d 0 to 84, or 2 kg/d of DDG from d 0 to 42. Timing of prepartum DDG supplementation did not impact cow reproduction, but calf pre-weaning growth was enhanced only when cows received longer vs. shorter or no periods of prepartum supplementation. Study 2evaluated the use of prepartum supplementation of sugarcane molasses/urea added or not with DL-methionine hydroxyl analog. At 56 d before calving, Brangus heifers received no supplementation or molasses/urea (7.2 kg DM/wk) with or without methionine (105 g/wk; Alimet, Novus) until calving. Sugarcane molasses/urea supplementation improved cow BCS at calving and calf postnatal growth compared to no supplementation. However, supplemental methionine did not further enhance cow and calf growth performance. Study 3 compared winter vs. annual supplementation of sugarcane molasses/urea or range cubes. Starting on d 0 (pregnancy diagnosis; May), Brangus cows were assigned to receive molasses/urea supplementation during winter only (calving until end of breeding season) or year-round supplementation of molasses/urea or range cubes. Treatments had similar annual supplement DM amount (272 kg/yr). Year-round supplementation of molasses/urea and range cubes enhanced cow BCS at calving but did not impact pregnancy rate of cows and calf weaning weights than winter molasses/urea supplementation.

Abstract This study investigated growth and reproductive performance of Bos indicus-influenced beef heifers provided a concentrate supplement at either a constant or stair-step supplementation. Sixty-four Brangus heifers were stratified by initial BW and age (255 ± 20 kg; 270 ± 22 d) and assigned to 1 of 16 bahiagrass pastures (4 heifers/pasture). Treatments were randomly assigned to pastures (8 pastures/treatment) and consisted of concentrate DM supplementation at: (1) 1.50% of BW from d 0 to 100 (CON) and (2) 1.05% of BW from d 0 to 49 and 1.95% of BW from d 50 to 100 (STP). Supplementation started on d 0 and continued until start of estrous synchronization on d 100. Intravaginal temperatures (16 heifers/treatment) were collected every 30 minutes from d 25 to 31 (September) and d 85 to 91 (November). All heifers were provided supplement at 1.50% of BW from d 101 to 211. Heifers were bred by AI from d 113 to 115 and Brangus bulls were placed with heifers from d 121 to 211. Data were analyzed using the MIXED procedure of SAS with treatment, time, and interaction as fixed effects. From d 0 to 49, ADG did not differ (P = 0.87); however, STP heifers had greater (P = 0.01; 0.73 vs. 0.56 kg/d) ADG from d 50 to 100 compared to CON heifers. Percentage of pubertal heifers, percentage of heifers in estrus, or reproductive tract scores did not differ between treatments (P ≥ 0.40). Intravaginal temperatures were greater (P < 0.0001) for CON vs. STP heifers from d 25 to 31 but did not differ (P = 0.74) from d 85 to 91. Using a stair-step vs. constant supplementation amount (1.05 to 1.95% vs. 1.50% of BW) before the breeding season reduced intravaginal temperatures and increased overall ADG in Bos indicus-influenced beef heifers.

Abstract This 2-yr study investigated the timing of dried distillers grains (DDG) supplementation of Bos indicus-influenced cows during late gestation and its impacts on offspring performance. On d 0, 84 Brangus cows/yr were stratified by BW (482 ± 75 kg) and BCS (5.3 ± 0.8) and randomly assigned to bahiagrass pastures (14 cows/pasture). Treatments were randomly assigned to pastures (2 pastures/treatment/yr) and consisted of no prepartum supplementation (CON), 2 kg/d of DDG from d 0 to 42 (LATE42), or 1 kg/d of DDG from d 0 to 84 (LATE84). At weaning (d 347), 38 steers/yr were vaccinated against bovine respiratory disease, transported for 720 mi to the feedlot, penned according to prepartum pasture distribution, and fed the same corn silage-based diet until harvest. Data were analyzed using SAS GLIMMIX procedure. Cow BCS at calving was greater (P ≤ 0.05) for LATE84 and LATE42 vs. CON cows and did not differ (P = 0.16) between LATE84 and LATE 42 cows. Cows offered LATE42 supplementation had greater (P ≤ 0.05) calving percentage from wk 2 to 6 of the subsequent calving season than CON and LATE84 cows. Calf BW at weaning was greater (P ≤ 0.05) for LATE 84 vs. LATE42 calves, and the latter greater than CON calves (269, 261, and 255 ± 2.6 kg, respectively). Seroconversion against parainfluenza-3 virus at weaning was greater (P ≤ 0.05) for LATE42 vs. CON steers, with LATE84 being intermediate. Feedlot BW and carcass weight did not differ (P ≥ 0.36) among treatments, but marbling scores and carcasses grading choice tended (P ≤ 0.10) to be greater for LATE42 vs. CON steers, with LATE84 being intermediate. Therefore, timing of DDG supplementation during late gestation in Bos indicus-influenced cows enhanced calf weaning weight, humoral immunity, and carcass characteristics at different magnitudes than cohorts born from non-supplemented cows.

Abstract This study compared the effectiveness of liquid sugarcane molasses/urea or wheat middlings-based range cubes supplementation on performance of beef cow-calf pairs. On d 0, 82 mature pregnant Brangus cows were stratified by BW and BCS (433 ± 47 kg; BCS = 4.6 ± 0.77) and randomly allocated into 1 of 6 bahiagrass pastures (13–14 pairs and 9.3 ha/pasture). Treatments were assigned randomly to pastures (2 pastures/treatment) and consisted of cows offered: winter supplementation of molasses/urea from calving until end of breeding season (d 161 to 300; MOL-W), or year-round supplementation of liquid urea/molasses (MOL-Y) or range cubes (CUB-Y). Supplement amount offered to cows differed monthly among treatments, but all cows were limit-fed 272 kg/yr of the respective supplement DM and similar trace mineral supplementation (336 g/cow/wk). Cubes were formulated to be isocaloric and isonitrogenous compared with molasses/urea (75% TDN, 20% CP; DM basis). Weekly supplement amount was divided in half and offered every Monday and Thursday. Cow BCS: did not differ among treatments from d 0 to 74 (P ≥ 0.56); was greater at calving (d 161) for MOL-Y and CUB-Y vs. MOL-W cows (P ≤ 0.05); and was greatest, intermediate, and least at start of breeding season (d 217) for MOL-Y, CUB-Y, and MOL-W cows (P ≤ 0.05), respectively. Liver concentrations for Co, Se, and Cu on d 122 and 217 were greater (P ≤ 0.02) for CUB-Y vs. MOL-W and MOL-Y cows. Calving date, percentage of pregnant cows on d 360, and calf birth BW, pre-weaning ADG, and BW at weaning did not differ (P ≥ 0.14) among treatments. Therefore, year-round supplementation of liquid molasses/urea and range cubes enhanced cow BCS at calving and start of breeding season but did not impact subsequent reproductive performance of cows and calf weaning weights than conventional winter molasses/urea supplementation of cows

Protein Nutrition

The transition period of the dairy cow is physiologically and nutritionally stressful as feed intake is reduced whilst nutrient demand for the support of foetal growth and initiation of milk synthesis are increased. Also during this period the diet of dairy cows changes from being predominantly forage, often of mediocre quality, to a diet often containing high levels of concentrate and high quality forage or mixture of forages. In the recent past nutritional management of the dairy cows during the transition period has centred on protein nutrition. While some studies have shown responses to milk yield or composition from protein nutrition in late gestation, many have shown no response. The objective of the present study was to examine the effects of level of concentrate in late gestation on subsequent reproductive performance. The effects of treatment on animal performance have been presented by Keady et al. (1999).

The aim of this study was to evaluate the reproductive performance of Ile de France ewes undergoing dietary supplementation before and during the breeding season, with and without association with management conditions (pre-mating shearing). Thirty-six ewes with an average body weight of 66 kg were used in the experiment. Treatments involved ewes receiving or not receiving concentrate supplementation (flushing), with groups subdivided according to the management condition to which animals were subjected: shearing or lack of it. Thus, ewes were divided into four treatments: flushed and shorn; flushed and unshorn; unflushed and shorn; and unflushed and unshorn. Flushing increased weight gain and body condition score, and when associated with shearing, it promoted anticipation of estrus. Fertility rate (86.05%), calving rate (77.77%), birth rate (113.83%), and type of birth (single: 82.29% and twin: 17.71%) were not influenced. Birth weight (3.96 kg) and prolificacy (1.25%) also were not affected. Despite the lack of changes in reproductive traits, flushing adopted during the breeding season associated with shearing anticipated estrus in ewes.
