This study evaluated the influence of a blended phytogenic feed additive on feed intake, feeding behavior, nutrient digestibility, and growth performance during feedlot adaptation, early, and late finishing periods as well as carcass traits. Twenty-six crossbred F1 Angus × Nellore bulls (19 mo ± 4 d) were housed in individually pens and fed a high-forage receiving diet for 7 days. At the end of the receiving period, bulls were weighted [initial shrunk body weight (SBW) 363 ± 20 kg], blocked by SBW and randomly assigned to two treatments; Control: without any additive or PHY: 150 ppm of a phytogenic feed additive fed throughout the adaptation and finishing phases. Bulls were transitioned through four steps over 18 days to a high-grain finishing diet (as % DM, 64% rehydrated corn grain silage, 19% corn gluten feed, 13% sugar cane bagasse and 4% minerals, urea, and vitamins mix). The finishing phase lasted 68 days, with mid-point measurements dividing early and late finishing period. The PHY group DMI was greater during adaptation and late finishing periods (P < 0.05), with a tendency during early finishing period (P = 0.06). Number of daily meals was similar between treatments (P = 0.52), but an increased meal length was noted for PHY group (P < 0.05), which contributed to their greater DMI. Diet digestibility remained similar between groups during the finishing periods (P > 0.1). Ruminitis scores were low and liver abscess similar between treatments. Final SBW tended to be higher (P = 0.09) and hot carcass weight was greater for the PHY group (P < 0.05), with no differences on dressing percentage, ribeye area and marbling score. In conclusion, the PHY treatment had positive effects on intake and carcass weight, without increasing metabolic disorders.

A study was conducted to evaluate the effects of supplementing feedlot finishing corn diets with dry corn gluten feed (CGF). Animal performance and carcass traits were compared with those obtained by feeding a barley-based diet typical of diets fed commercially in western Canadian feedlots. The second objective of the experiment was to evaluate the diets using the 1996 National Research Council (NRC) Beef (level 1 and 2) and Cornell Net Carbohydrate and Protein System (CNCPS, version 5.0) models to determine how well the models predict animal response. Crossbred beef steers (248) weighing 423 ± 20.5 kg were allocated to 24 pens and then six pens were assigned to each of four diets: (1) barley grain (13.8% crude protein, CP), (2) corn grain (9.2% CP), (3) corn grain supplemented with a low level (7%, DM basis) of CGF (CGF-low, 9.7% CP), and (4) corn grain supplemented with a high level (23%) of CGF (CGF-high, 11.7% CP). The barley grain was steam-rolled and the corn grain was dry-rolled. All diets contained 8% barley silage (DM basis). The cattle were adapted from a backgrounding diet to the experimental diets over a period of 28 d and then fed for a period of 136 d. During the adaptation phase cattle fed unsupplemented corn grew slower (P < 0.05) than the cattle fed the other diets (1.23 vs. 1.52 kg d-1). However, after day 42 of the study, cattle fed unsupplemented corn grew very rapidly such that gain for the entire feeding period was similar for cattle fed unsupplemented corn and barley diets (1.62 vs. 1.58, P > 0.05). Furthermore, growth rate was higher (P < 0.05) for cattle fed barley or unsupplemented corn than for cattle fed low or high levels of CGF (1.48 and 1.45 kg d-1, respectively). The dry matter intake (DMI) averaged 11.4 kg d-1 during the feeding period and was not affected (P > 0.05) by diet. Feed:gain ratio (kg DM:kg gain) was similar (P > 0.05) for cattle fed barley (7.09) and unsupplemented corn (7.38), but was higher (P < 0.05) for cattle fed CGF-high (7.92), and intermediate (P > 0.05) for those fed CGF-low (7.52). There were no differences in carcass composition between barley and corn-fed cattle, but those fed low and high levels of CGF had carcasses that were fatter with lower lean meat yield. The three models underestimated DMI of all four diets. When DMI was set to observed intake in the models, CNCPS accurately predicted ADG and F:G ratio for cattle fed corn diets, but all models underestimated ADG of cattle fed barley. All models correctly predicted that gain during the feeding period was not limited by protein supply. The results from this study indicate that rolled-corn diets containing about 9.5% CP, with 50% of the CP as DIP are adequate for feedlot cattle weighing more that 500 kg. Substituting dry CGF for corn grain reduces feed efficiency and gain due to the lower digestible energy content of CGF.

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

Abstract A duplicated 4 × 4 Latin square design evaluated the effects of replacing ground corn grain (GCG) by sugar-based byproducts plus corn gluten feed (SBB-CGF) on ingestive behavior and ruminal fermentation parameters in small ruminants. Four ruminally cannulated wether sheep and four wether goats (72 and 65 ± 2.3 kg BW, respectively) were individually allocated to 8 pens, over 4 periods of 19-d each (12 d adaptation plus 7 d of sample collection) to receive a diet containing 50% roughage (bermudagrass hay; Cynodon sp.) and 50% concentrate (80% GCG, 16% soybean meal, and 4% premix) with 4 levels of inclusion of SBB-CGF in replacement of GCG (0, 33, 66, and 100%, DM basis). Corn gluten feed was used with SBB to maintain the diets isonitrogenous. Ruminal fluid was collected at 0, 2, 4, and 6 h after the morning feeding, whereas ingestive behavior was assessed on the d 12 of each period for 24 h. Resting time linearly increased with greater inclusion levels of SBB-GCF (P = 0.04; 15.6, 15.7, 16.0, 16.8 h/d). Rumination time was greater (P = 0.001), whereas resting time was lower (P = 0.002) for wether sheep vs. goats (6.5 vs. 4.3 h/d and 15 vs. 17 h/d, respectively). Ruminal concentrations of ammonia-N (P = 0.05; 13.3, 13.2, 10.4, and 10.4 mg dL-1), acetate (P = 0.001; 58.9, 49.6, 48.5, and 43.1 mM), and acetate:propionate ratio (P &lt; 0.001; 3.6, 2.4, 2.0, and 1.9 mM) linearly decreased, whereas propionate concentrations (P = 0.01; 17.9, 23.0, 30.6, and 28.8 mM) linearly increased with greater levels of SBB-GCF in the diet. In conclusion, sugar-based byproducts plus corn gluten feed can replace ground corn grain up to 100% in the diets of goats and sheep consuming a 50:50 roughage:concentrate diet without compromising the ingestive behavior and ruminal fermentation parameters.

Abstract Twelve dual-flow continuous culture fermenters (1.95 L) were used to evaluate the effect of a phytogenic feed additive (Actifor Pro, Delacon, Engerwitzdorf, Austria; ACT) on ruminal fermentation and methane production when fed high fiber diets, comprised of bermudagrass hay (BGH) with or without corn gluten feed (CGF). Fermenters were utilized in a generalized randomized block design with a 2 × 2 factorial arrangement of treatments (n = 6): 1) diet (with or without CGF at 22% of diet DM) and 2) additive (with or without ACT at 1.0 g/L ACT). Two 10-d periods were conducted. Overall, comparing to no CGF, supplementation with CGF resulted in lower dry matter, organic matter, crude protein digestibility, microbial efficiency of nitrogen utilization, and methane production (mL of CH4/mol of total VFA), but increased neutral detergent fiber digestibility (all P ≤ 0.05). Diet × additive interactions were observed for molar proportion of acetate and propionate, and acetate-to-propionate ratio (A:P, all interactions P &lt; 0.05), where inclusion of ACT increased acetate molar proportion and A:P (both P &lt; 0.05), and decreased propionate molar proportion in diets with CGF (P = 0.05). A diet × additive interaction was also observed for methane production (ml of CH4/mol of total VFA; P = 0.08), where ACT decreased CH4 production per mol of VFA by 42% (P = 0.04), when only BGH was fed to the fermenters. In conclusion, CGF supplementation in BGH diets reduced methane production and improved fiber digestibility. The decrease in methane production per mol of VFA observed with ACT in the BGH without CGF diet warrants further investigation.
