Abstract This study assessed the effect of Sweet BranTM (SWBR; 40% DM inclusion; Cargill Corn Milling, Blair, NE) or modified distiller’s grains (MDGS; 25% DM inclusion) in the diet of newly received feedlot steers on feeding behavior and growing period performance. Diets were formulated for similar metabolizable protein and DM. Two hundred sixteen freshly weaned Angus-cross steers (253 kg ± 18.1) were stratified by BW to 36 pens (n = 18 per treatment; 6 steers/pen). Individual BW were recorded on d 0, 28, and 60. Eight pens per treatment were utilized to assess rate of feed disappearance early (day 5 and 6) and late (53 and 54) during growing by weighing feed in bunks every 2 hours post-delivery for 12 consecutive hours. Feed weights were averaged across consecutive days within pen and timepoint. Slopes were calculated between each timepoint to determine rate of feed disappearance. Data were analyzed with Proc Mixed of SAS 9.4; diet was fixed effect and pen was experimental unit. Feed disappearance slopes were analyzed as repeated measures with the repeated effect of time. Body weights did not differ on d 28 (P ≥ 0.29), but d 60 BW and d 0 to 60 ADG were greater for SWBR than MDGS (P < 0.05). Steers fed SWBR had greater DMI throughout the trial (P < 0.05). Feed efficiency (G:F) did not differ throughout the trial (P ≥ 0.31). Rate of feed disappearance on d 5/6 was greater for SWBR between hours 6–8, and greater for MDGS from hours 10–12. On d 53/54, SWBR had increased feeding rate during hours 0–2, while MDGS was increased from hours 8–10. Steers fed SWBR had a greater rate of feed disappearance earlier in the day and had improved DMI and growth than steers fed MDGS.

Abstract The objective of this study was to determine the effects of an immunomodulatory feed ingredient during post-weaning on growth and cortisol levels of beef heifers. Commercial Angus heifers (n = 72) from two AI sires were blocked (n = 9) by sire and BW and then randomly assigned to one of two pens per block. Each pen (4 heifers/pen) per block was assigned to one of the treatments. Heifers were fed a commercial TMR twice daily from d 0 to 60 to gain 0.75 kg/day. The feed was top-dressed once a day with either 72g of Celmanax (CEL) or 72g of corn germ (CON) per pen. Body weight was collected on d -1, 0, 15, 30, 45, 60 and 61. Blood samples were collected on d 0, 15, 30, 45 and 60. Sixteen heifers (n = 8 CEL; n = 8 CON) were randomly selected for a corticotropin releasing hormone/ arginine vasopressin (CRH/AVP) challenge after the 60 d period. Two heifers per pen (n = 32) were randomly selected for a transportation challenge to evaluate stress response on d 61 or 62 of the study. Pen was the experimental unit and data was analyzed by ANOVA or repeated measures analysis as appropriate. Feed efficiency and BW gain was increased (P = 0.04) in CEL heifers compared to CON heifers. Serum cortisol concentrations were decreased (P < 0.01) in CEL heifers compared to CON heifers on d 30 to 60 post-weaning. Serum cortisol concentrations were decreased (P < 0.05) in CEL heifers compared to CON heifers during the CRH/AVP challenge from 60 to 150 minutes post infusion. Serum cortisol concentrations were decreased (P < 0.05) in CEL heifers compared to CON heifers throughout the transportation challenge. In summary, supplementation of Celmanax post-weaning increased BW gain and reduced cortisol concentrations in beef heifers.

Abstract Four hundred forty weaned pigs, initial weight of 5.86 kg and 21 days of age, were used to evaluate the effect of feeding a LucraFit® nursery program on piglet performance. Pigs were randomly assigned to one of two treatments Control or LucraFit® with 12 replicates per treatment and 20 pigs per pen. Pigs were fed a four-phase nursery feed budget of 1.13, 2.27, 5.44, and 20.64 kg/pig for phases 1–4, respectively. Control diets contained 18% lactose in phase 1 and 0% in phase 2, 3, and 4. LucraFit® diets contained 0% lactose and LucraFit® was added at 2.5, 2.5, 1.25% in phase 1, 2 and 3, respectively. Body weights were taken on day 0, 8, 15, 22, 29, 36, and 43 with corresponding ADG, ADFI, G:F calculated. Data were analyzed using the Mixed procedure of SAS with pen as experimental unit. Period 1 (d0 to 8) ADG tended to increase (P < 0.10;0.188 vs 0.175 kg/d) and G:F increased (P < 0.05;1.38 vs 1.06) in the LucraFit® treatment. Period 1 ADFI was greater (P < 0.05) for the Control treatment (0.166 vs 0.141 kg/d). Period 2 (d8 to d 15), LucraFit® treatment tended (P < 0.10) to increase ADG (0.416 vs 0.398 kg/d) and increased (P < 0.05) G:F (0.973 vs 0.894). Period 3 (d15 to d 22), ADFI was increased (P < 0.05) with LucraFit® treatment (0.628 vs 0.577 kg/d) and therefore increased (P < 0.05) G:F for Control treatment (0.794 vs 0.752. Period 6 (d36 to d 43), LucraFit® treatment increased (P < 0.05) ADG (1.57 vs 1.40 kg/d) and G:F (0.565 vs 0.500). Overall (d0 to 43) Gain:Feed was increased (P < 0.05) with LucraFit® treatment (0.713 vs 0.691). Final nursery body weight (d 43) tended (P = 0.08) to increase with LucraFit® treatment (27.05 vs 26.32). The results of this study suggest that feeding LucraFit® in lactose free nursery diets improves feed efficiency.

One hundred ninety-two male broiler chicks were dosed with monensin at concentrations of 0, 121, or 242 mg/kg feed throughout the normal growing period (50 days). Body weight gain and feed efficiency were determined weekly, and cardiac muscle was examined grossly and histologically at the end of the experiment. Livers also were weighed and examined grossly. Feed intake was determined daily, allowing continuous monitoring of drug intake. No depressing effects of the drug on growth rate and efficiency were observed until after four weeks, and then were evident only in the chicks receiving the 242 mg/kg diet. Subepicardial hemorrhage and congestion occurred in 40% of the hearts from the chickens fed the high monensin dose and were nonexistent in the other treatments. There appeared to be an inverse relationship between monensin dose and liver weight. The paralytic effects previously reported from acute dosing experiments were not observed. The results show that the heart and probably the liver are sensitive indicators of monensin toxicity and that the subchronic toxic dose is less than 18 mg/kg body weight per day.

Octopuses (Eledone cirrhosa (Octopoda: Cephalopoda)) held in an aquarium were subjected to varying conditions of feeding and starvation to evaluate putative indices of feeding and growth. Specific growth rate (%d−1) was linearly related to feeding rate (% of the body mass d−1) in animals with a mean body mass of 250 g at 15°C. Maximum growth rates varied between > 2% d−1 (body weights < 300 g) to < 1% d−1 (body weights ≤ 900 g) but specific growth rates were not related to body weight. Growth rates became negative (weight loss) after one week without food.The digestive gland index (DGI) was significantly correlated with short and long-term feeding and specific growth rates, and with body weight. Muscle RNA concentration was linearly correlated with growth rate during the previous 1–3 weeks but not with feeding rate. RNA:protein ratios were not different between mid-arm and mantle sample sites but arm tip values were significantly higher. RNA:protein ratio was related to body weight only in feeding animals. It is concluded that DGI is an index of feeding rate and that RNA:protein ratio can be used as an index of recent (~ 4 weeks) growth rate.

Abstract To assess relative bioavailability of an organic Cu source, 90 Angus-cross steers (265 ± 21 kg) were blocked by body weight to pens with GrowSafe bunks and randomly assigned to dietary Cu treatments (14–18 steers/treatment): 0 mg Cu/kg dry matter (DM; CON), 5 or 10 mg Cu/kg DM as Cu sulfate (CS5; CS10) or chelated bis-glycinate Cu (GLY5; GLY10). Steers were fed a common high antagonist growing diet (0.48% S; 5.3 mg Mo/kg DM; 4.9 mg Cu/kg DM). Blood was collected from all steers on d 0, 28, 56, 84 and 124. Liver samples were collected at trial beginning (d -3/-2) and end (d 125/126). Data were analyzed using ProcMixed of SAS (experimental unit = steer; fixed effect = treatment; random effect = block). Plasma Cu was analyzed as repeated measures (repeated effect = day). Plasma and liver Cu concentrations were regressed against Cu intake using ProcGLM to calculate relative bioavailability of GLY. Initial liver Cu did not differ between treatments (P ≥ 0.63), but final liver Cu was lesser in CON versus steers supplemented 5 or 10 mg Cu/kg DM from either source (P ≤ 0.09). Final liver Cu was greater for CS versus GLY (P &lt; 0.01). Plasma Cu for all treatments decreased through d 28; final plasma Cu was greatest for steers supplemented either source at 10 mg Cu/kg DM (treatment × day P &lt; 0.01). Relative bioavailability of GLY was 82% compared to CS (P &lt; 0.01) based on liver Cu but did not differ based on plasma Cu (P = 0.60). High concentrations of dietary antagonists and lower solubility of GLY (68.9% relative to CS) in rumen-like conditions (pH 5.2) may have resulted in free thiomolybdate absorption across the rumen wall and subsequent depletion of liver Cu stores in GLY supplemented steers.

Experiments were conducted to determine the effect of feeding a high (19.6%) or low (7.7%) fiber diet to meat- and egg-type chickens during the last 6 wk of their growing period followed by a high (12.4%) or low (6.2%) fiber diet during the breeding period. The addition of finely ground wheat straw at 40% of the ration during 15–21 wk of age resulted in a significant reduction in feed consumed, exclusive of the added fiber, per hen–day in both strains and a reduction in body weight gain per bird, but it had no effect on feed conversion efficiency. The addition of fiber also resulted in a significant increase in weight (and size) of various components of the digestive system in both strains when this was prorated to body weight. The carryover effects of feeding high fiber during the growing period were manifested by increased rate of lay and body weight gain in both strains, irrespective of the breeding period diet. However, pre-treatment on high fiber growing diet resulted in increased feed efficiency of both strains of hens fed a low fiber breeding diet, but not of the hens fed a high fiber breeding diet. The high fiber rations (20% wheat straw) fed during the breeding period depressed rate of lay and feed efficiency but did not affect the weight, quality, fertility or hatchability of the eggs. Mortality during the growing and breeding periods was not affected by the high fiber diet. Apparently chickens are capable of a high degree of anatomical and physiological adaptation to compensate for variation in nutrient concentration of their diet. Such adaptation during the growing period showed some beneficial effects on breeding period performance in meat- and egg-type chickens.
