Abstract The objectives were to analyze the effects of housing cow-calf pairs in drylots or pasture on calf performance and behavior through the receiving phase. Simmental × Angus (2 yr; 108/yr; 81 ± 15.3 d postpartum) spring-calving cows were stratified by age, BW, BCS, and calf sex and allotted to six groups/yr. Groups were randomly allotted to 1 of 2 treatments: drylot (DL) or pasture (PAST). After weaning, calves were shipped 262 km to a feedlot for a 42 d receiving period. All calves were fed a diet consisting of corn silage, wet distillers grains, corn, and grass hay during the receiving phase. Behavior was evaluated on d 1 and d 2 after arrival. Calf BW was measured on d 0, 21, and 42. Average daily gain (ADG), dry matter intake (DMI), and feed efficiency were also determined. The data were analyzed using the MIXED procedure of SAS. On day 1, there was a treatment by time interaction for lying (P = 0.04). At h 2, 4, and 11 more PAST calves were lying. There was a tendency (P = 0.08) for PAST calves to spend more time eating. More DL calves vocalized (P = 0.03). On day 2, there were treatment by time interactions (P ≤ 0.02) for lying and walking. More PAST calves were lying at h 1, 2, 8, 9, and 12. More DL calves were walking at h 2, 11, and 12. Pasture calves had greater (P < 0.01) ADG and G:F than DL calves. However, the DL calves had greater (P ≤ 0.02) BW at d 0, 21, and 42. In conclusion, calf behavior at receiving was influenced by preweaning housing. Additionally, pasture calves had improved receiving phase ADG and feed efficiency but were still lighter than drylot calves after 42 d receiving phase.

Abstract The objectives were to analyze the effects of housing cow-calf pairs in dry lots (DL) or pasture (PAST) on calf performance and behavior through the receiving phase. Simmental × Angus (n = 108; 87 ± 11.5 d postpartum) spring-calving cows were stratified by age, BW, BCS, and calf sex and allotted to six groups. Cows were limit-fed a ration consisting of corn silage, dried distillers grain, corn stalks, dry rolled corn (DRC), and soybean hulls to meet protein and energy requirements. Calves had ad libitum access to same diet in an adjacent pen. Calves on PAST were rotationally grazed with free-choice mineral. After weaning (177 ± 11.5 d of age) all calves were fed a diet consisting of corn silage, wet distiller grains, DRC, and grass hay during the receiving phase (42 d). At the age 87, 142, 177, 198, and 219 ± 11.5 d, BW was measured. Hair coat score (HCS) and dirt score (DS) were measured on d 0 and d 90. Calf behavior was observed after feedlot arrival. Average daily gain, DMI and feed efficiency were also analyzed. The data were analyzed using the MIXED procedure of SAS. Dry-lot calves had greater (P < 0.01) BW and ADG prior to weaning. Calves from PAST had lower (P < 0.01) DS and greater (P < 0.01) HCS at weaning. Upon feedlot arrival, more (P < 0.01) DL calves were walking and had increased (P < 0.01) vocalizations. Calves from PAST had greater (P < 0.01) ADG, DMI as a percent of BW, and gain:feed than DL calves during the receiving phase. Calves raised in a dry lot had greater BW and ADG prior to weaning, but PAST calves had fewer behavioral signs of stress and greater growth performance in feedlot.

Abstract The objectives were to analyze the effects of housing cow-calf pairs in drylots or pasture on calf performance and behavior through weaning. Simmental × Angus (2 yr; 108/yr; 81 ± 15.3 d postpartum) spring-calving cows were stratified by age, BW, BCS, and calf sex and allotted to six groups/yr. Groups were randomly allotted to 1 of 2 treatments: drylot (DL) or pasture (PAST). Calves in the drylot had ad libitum access to a diet consisting of corn silage, dried distillers grain, corn stalks, dry rolled corn, and soybean hulls. Calves on PAST received creep feed three weeks prior to weaning. Calf BW was measured on d 0, 55, and 110. Calves were fence-line weaned on d 110. Behavior was observed for two days after weaning. Data were analyzed using the MIXED procedure of SAS. Drylot calves had greater (P &lt; 0.01) BW at d 55 and 110. There was treatment by time interactions (P &lt; 0.01) for lying and eating on d 111. More PAST calves were lying at h 2 and 3 and eating at h 11 and 12. More DL calves were lying at h 9, 10, 11, and 12. More DL calves were eating at h 2 and tended to at h 3. There was also a treatment by time interaction (P &lt; 0.01) for vocalizations on d 111. More PAST calves vocalized at h 1, however, DL calves vocalized more at h 4 and tended to at h 5. There was treatment by time interactions (P &lt; 0.01) for eating and walking on d 112. More DL calves were eating at h 2, 3, 4, 7, and 9. More PAST calves were walking at h 1 and 2. There was also a treatment by time interaction (P &lt; 0.01) for vocalizations on d 112. More PAST calves vocalized at h 1 and 10. In conclusion, housing cow-calf pairs in drylots improved preweaning performance and altered postweaning behavior.

Abstract Corn hybrids can be selected for improved digestion rates using lab techniques, which should impact animal performance. The objective of this study was to evaluate two Masters Choice corn silage hybrids on growing steer performance. In an 84-day growing study, 288 crossbred steers (initial BW = 303 ± 12 kg) were utilized in a generalized randomized block design with three diet treatments, 12 steers per pen and 8 pen replicates per treatment. Diets consisted of 80% corn silage (DM basis) of Masters Choice hybrid MCT6365 RIB (MC1, that has been selected to improve fiber and starch digestion) and MCT6733 GT3000 (MC2, that has been selected to improve fiber digestion) were compared to a conventional corn hybrid Farm Choice (CON, that is commonly grown in Eastern Nebraska). All corn was grown in one field under identity preserved method and harvested at 37-38% DM in three consecutive days. Relative to CON, feeding MC1 resulted in similar dry matter intake (DMI, P = 0.28), but numerically increased average daily gain (ADG, P = 0.14) which significantly improved feed efficiency (G:F, P = 0.02). Feeding MC2 led to greater DMI (P &lt; 0.01), similar ADG (P = 0.45), and lower G:F (P &lt; 0.01) compared to CON. The results suggest that feeding Masters Choice hybrid MCT6365 RIB (MC1) corn silage at 80% of the diet DM improved ADG and G:F by 4.2%, while feeding MC2 decreased G:F by increasing DMI compared to CON. Differences in corn hybrids exist when feeding growing cattle 80% silage.

Forty-eight Cu-depleted beef steers were used in a 105-d growing trial to compare four methods of Cu supplementation. Corn silage-barley concentrate diets were supplemented to contain 10 mg kg−1 dry matter (DM) Mo, and 1.3 (low S) or 3.7 (high S) g kg−1 total S. Copper treatments within low and high S diets were: (1) no supplemental Cu (0Cu); (2) a dietary supplement of 10 mg kg−1 DM Cu in the complete feed, added as CuSO4∙5H2O to the concentrate (CuSO4); (3) 20 g copper oxide needles (CuON) orally dosed on day 0; and (4) injectable Cu (ICu) on day 0. Although average daily gain was not different (P > 0.05) among Cu treatments, DM intake was lower (P < 0.05) with CuSO4 and CuON than with 0Cu or ICu. Feed efficiency (FE; feed:gain ratio) was better (P < 0.05) with CuSO4 (FE = 5.60) than 0Cu (FE = 6.88), while CuON (FE = 6.04) and ICu (FE = 6.16) FE were intermediate to 0Cu and CuSO4. Increasing dietary S from 1.3 to 3.7 mg kg−1 DM resulted in lower (P < 0.01) concentrations of Cu and Mo in liver and plasma, and plasma ceruloplasmin activity. An improvement of FE with CuSO4 was related to increased Cu and lower Mo concentrations in the plasma and liver of steers. With ICu there was some indication of an improvement of Cu status. With CuON, measured parameters were indicative of a metabolic Cu insufficiency, but with a lower concentration of Mo in plasma. At the levels of supplementation used in this trial, CuSO4 was a better Cu supplement than CuON or ICu for cattle consuming diets containing excess Mo or Mo plus S.

Abstract Objectives were to compare feedlot performance and carcass traits of F1 beef × Holstein steers and Holstein steers. Angus or Limousin × Holstein crossbred [n = 27; age = 12 ± 3 months; body weight (BW) = 435 ± 8 kg] and Holstein (n = 20; age = 11 ± 2 months; BW = 400 ± 9 kg) steers were fed at the Pennsylvania Department of Agriculture Livestock Evaluation Center for 111 days. Feed intake was recorded using the GrowSafe Feed Intake Monitoring System (Model 4000E, GrowSafe Systems Ltd., Calgary AB, Canada). The diet contained corn silage, dried distillers grains, soybean meal, and cracked corn and was formulated to meet or exceed the requirements of beef cattle (NASEM, 2016). Growth performance variables of interest and carcass measurements were analyzed with the Mixed procedure of SAS (SAS 9.4; SAS Institute Inc., Cary, NC). USDA assigned quality grades (QG) and yield grades (YG) were analyzed the with GLIMMIX procedure of SAS. Breed was a fixed effect in all models. There were no differences (P &gt; 0.05) between breeds in average daily gain or feed efficiency. Crossbreds exceeded Holsteins in initial (P &lt; 0.01) and final BW (P = 0.01), dry matter intake (P = 0.03), hot carcass weight (P &lt; 0.01), backfat (P = 0.03), and ribeye area (REA; P &lt; 0.01). Thirty-five percent (35%) of the Holsteins received a QG of Choice or above while 74% of crossbreds graded USDA Choice or above (P = 0.01). However, 75% of Holsteins were YG 2 or lower while only 45% of crossbreds achieved YG 2 or less (P = 0.05). There was no improvement in efficiency when crossbreds were compared to Holsteins; however, carcasses from crossbreds were more likely to grade USDA Choice or above while yielding greater REA and backfat than Holsteins.

Abstract The aim of this trial was to evaluate the effect of encapsulated calcium ammonium nitrate as a partial substitute for soybean meals in the concentrate dry matter intake, average daily gain and feed efficiency of Nellore young bulls under grazing conditions, during the dry season. Sixty-four weaned Nellore (initial BW = 177.46±3.77 kg and 9 mo old) were used in a completely randomized assay. The study lasted 84 days on the dry season. Animals were allotted into 16 paddocks of 1.0 ha each of Urochloa brizantha, randomly assigned into one of two treatments: (CTL) supplement with 25% CP, without nitrate inclusion and; (ENP): supplement with 25% CP, with a inclusion of 50 g of encapsulated calcium ammonium nitrate to each 100 kg of body weight. Animals were fed with concentrate at 1.0% of body weight. Concentrate offered was monitored daily as well as his refusals were collected and weighed to determine daily concentrate dry matter intake (DMI) and feed efficiency (F:G). Animals were weighed every 28 d for calculating average daily gain (ADG). Data were analyzed as a completely randomized design, using ANOVA (α = 0.05). No effects of treatments (P &gt; 0.3487) were observed for final BW (246.69 kg). The same for concentrate dry matter intake (P &gt; 0.0550). Animals consumed 2.34 kg of supplement per day. The average daily gain (0.832 kg, P &gt; 0.2649) and feed efficiency (0.356 kg, P &gt; 0.7315) were not affected by the inclusion of nitrate. The inclusion of encapsulated calcium ammonium nitrate in supplement to Nellore young bulls under grazing conditions during the growing phase did not affect the performance.

This study evaluated food intake and productive performance of crossbred (½ Santa Inês x ½ dorper) lambs supplemented with different levels of faveleira (Cnidoscolus quercifolius Pohl) fodder salt. Thirty male sheep fed tifton grass hay, water, and faveleira fodder salt were randomly allocated into five treatments with six replicates each. The treatments consisted of diets with different inclusion levels of faveleira hay in the fodder salt composition: Treatment 1 (1% mineral salt + 99% faveleira hay), Treatment 2 (3% mineral salt + 97% faveleira hay), Treatment 3 (5% mineral salt + 95% faveleira hay), Treatment 4 (7% mineral salt + 93% faveleira hay), and Treatment 5 (Control - 100% mineral salt). Intake of dry matter, tifton hay and water, average daily gain, feed conversion, and feed efficiency were not affected by fodder salt supplementation (P > 0.05). There was a significant difference (P < 0.05) in fodder salt intake between Treatments 4 and 5, and daily intake was higher in animals submitted to Treatment 4 (61.0 g day-1). Mineral salt intake increased significantly with increasing mineral salt levels in the diet. However, no significant difference was observed in average daily gain across treatments, indicating that faveleira hay, even in small quantities, and tifton hay were able to meet the nutritional requirements of animals to support a good average daily gain. The inclusion of up to 99% faveleira hay in fodder salt formulations did not affect voluntary intake of forage, water and dry matter, average daily gain, feed conversion, and feed efficiency. Lambs supplemented with faveleira fodder salt had average daily gains within the optimal range for slaughter and high feed conversion and feed efficiency values. Faveleira was shown to be an effective supplementary feed alternative in sheep.

A trial involving a 2x2 factorial arrangement of treatments was conducted to evaluate two corn silage hybrids (Agromen, AGN35-A42) and (Bayer, A3663) and concentrate levels (25 and 50%) on animal performance. Twenty-four Holstein x Zebu crossbred steers, averaging 335±30kg of BW, were distributed in six randomized blocks to evaluate intake, digestibility, and performance. Treatments consisted of 75% corn silage A + 25% concentrate, 50% corn silage A + 50% concentrate, 75% corn silage B + 25% concentrate, and 50% corn silage B + 50% concentrate (dry matter basis); formulated to be isonitrogenous (13% crude protein, dry matter basis). There were no differences in the daily intakes of dry matter (DM), organic matter (OM), and crude protein. Additionally, there was a concentrate effect on non-fiber carbohydrates and total digestible nutrients intakes, and on total apparent digestibility of DM and OM, with higher intakes for steers fed diets with 50% of concentrate. However, average daily gain (ADG) was not influenced by treatments. The utilization of both corn silage hybrids in association with 25% of concentrate is a good option to feed crossbred steers with ADG close to 1.0kg in order to reduce diet cost.

Abstract Poor udder and teat confirmation decreases profitability due to decreased calf weaning weight, increased incidence of mastitis and labor, and decreased cow lifetime productivity. Therefore, the objective of this retrospective study was to evaluate the effect of beef cow udder score on cow performance and pre- and postweaning progeny performance. In a 5-yr study, crossbred cows at the Gudmundsen Sandhills Laboratory, Whitman, NE, were assigned an udder score each year at calving, from 1 to 5, using an udder and teat combination score. Cows were grouped by udder scores and classified as either low udder score (LUS, udder score 1 or 2; n = 223) or high udder score (HUS, udder score 3 or 4; n = 1,742). The udder score combines udder conformation and a teat scoring system. Low udder scores consisted of pendulous udders and large teats, whereas HUS consisted of tight udders and small, symmetrical teats. Mixed models were used to evaluate udder score on cow performance and calf pre- and postweaning performance. Cow body weight (BW) at prebreeding and weaning was greater (P &lt; 0.01) in LUS cows compared with HUS counterparts. Pregnancy rate was not different (P = 0.35) between udder classification groups. Calf BW at birth (P = 0.95), weaning (P = 0.40), and adjusted 205-d BW (P = 0.28) were not different between udder groups. Cow udder score did not influence feedlot entry (P = 0.41) and final BW (P = 0.30), dry matter intake (P = 0.53), average daily gain (P = 0.60), and gain:feed ratio (P = 0.85) of steer progeny. However, steers from HUS dams had greater hot carcass weight (HCW; P = 0.04) and backfat thickness (P = 0.02) compared with LUS counterparts. Results from this study suggest cows with less desirable udder structure may not have a negative impact on calf preweaning growth and performance; however, backfat thickness and HCW in the finishing phase were lower in steers from cows with a lower udder score.
