Abstract The objective of this study was to evaluate the effects of Levucell SC (LY; Saccharomyces cerevisiae CNCM I-1077) supplementation on performance, feed efficiency, ruminal temperature, feeding behavior, and carcass quality traits in yearling steers. Forty-eight crossbred steers were randomly allocated into two treatments: (1) Control and (2) LY with two pen replicates per treatment (12 steers per pen). Steers were housed in pens equipped with GrowSafe and fitted with reticulo-rumen boluses. All steers were maintained on their respective dietary treatments until harvest to assess carcass traits. There were no differences amongst treatments in DMI, ADG, morbidity or mortality rates, ruminal temperature or F:G. Live-yeast supplemented steers had 17% greater (P = 0.05) backfat thickness than control steers, which resulted in a 13% increase in yield grade, with no differences in all other carcass traits. Live-yeast steers exhibited different feeding behavior patterns than control steers, such that LY steers approached the bunk 25 minutes earlier (P = 0.01) than control steers, had 22% greater (P < 0.05) bunk visit (BV) duration, 41% increased (P < 0.05) head down duration, 18% slower (P < 0.05) BV eating rates, and a tendency for 9% lower BV frequency. Meal criterion was 47% longer (P = 0.01) for LY steers resulting in a reduction (P = 0.07) in meal frequency. Additionally, LY steers consumed 27% longer meals (P < 0.05) that tended to be larger in size (P = 0.09). Although DMI was not different throughout the trial, LY displayed 10% decreased (P < 0.05) meal-eating rates due to longer meal lengths. Overall, LY steers approached the feed bunk sooner following feed delivery, ate fewer, but larger meals at a slower rate, and spent more time eating compared to control steers. Live-yeast supplementation clearly altered feeding behavior patterns, suggesting more favorable fermentation and the capability to mitigate metabolic stress in steers fed high-grain diets by altering meal patterns.

 A dose-response experiment with 5 total dietary threonine (Thr) levels (0.54, 0.64, 0.74, 0.84 and 0.94%) was conducted to study the effect of dietary Thr on growth performance and carcass traits of Yangzhou geese from 0 to 8 weeks of age. Three hundred 1-day-old Yangzhou goslings were randomly allocated to 15 pens with 20 birds (10 males and 10 females) per pen according to similar pen weight. There were 5 dietary treatments, consisting of 3 replicate pens. Weight gain, feed intake and feed/gain of geese from each pen were measured at 2-week intervals from 0 to 8 weeks. At 56 days of age, four geese (2 males and 2 females) were selected randomly from each pen and slaughtered to evaluate the carcass quality. The results showed that an increase in dietary Thr resulted in an increase and then a decrease in daily weight gain in both periods. Peak daily weight gain responses appeared in geese fed the 0.74%Thr diet in both periods (36.120 and 61.96 g, respectively). Thr supplementation significantly affected feed/gain in the 0–4 week period (P ≤ 0.045) and daily feed intake in the 5–8 week period (P ≤ 0.012). No significant linear or quadratic responses from Thr supplementation were observed in growth performance and carcass traits of geese except for eviscerated carcass percentage (quadratic effect, P ≤ 0.016). The optimal Thr requirement of Yangzhou geese from 0 to 8 weeks of age was 0.726% for eviscerated carcass percentage. The results of our experiment reported herein would document that the Thr requirements suggested by NRC (1994) for geese up to 8 weeks of age are safe estimates; they may slightly overestimate the requirements but not by a large margin.

Abstract Weaning imposes multiple stressors that reduce feed intake and impair intestinal integrity. Furthermore, poor environmental management could compound the high stress period increasing morbidity and mortality of postweaning piglets. The objective of this research was to investigate the effect of supplemental Saccharomyces cerevisiae (ActiSaf HR+®) on postweaning growth performance, fecal scores and immune parameters in a clean or dirty nursery environment. The experiment was a 2 X 2 factorial design with 2 dietary treatments fed in a sanitized (following barn SOP) and un-sanitized (pits flushed, feeders and pens scraped) nursery environment. Weaned piglets (n = 260 and 5pigs/pen; 14.7±1.5lbs wt., 20.8d of age) were allotted to the following dietary treatments: 1) control or 2) ActiSaf HR+® (0.1% in phase 1 and 2 and 0.05% phase 3 diets) for 5-wks postweaning. On days 3, 7, 14, 21 and 35 fecal scores/pen and blood samples were collected for monitoring diarrhea and measurement of cytokines. Overall, pigs fed ActiSaf tended towards greater ADG compared to control fed pigs regardless of environment (P = 0.09; 379 vs. 357 g/d, ActiSaf vs control, respectively). Final pen weights at d35 were greater in ActiSaf vs. control fed pigs (101 vs. 97 kg/pen; P < 0.05). Pigs reared in the dirty vs clean environment had reduced overall ADG (352 vs 384 g/d, respectively; P = 0.01), and pigs in the dirty environment tended towards higher overall feed:gain compared to pigs in clean environments; 1.87 vs. 1.76 g/g (P = 0.09). Diarrhea scores were increased in the dirty environment compared to the clean environment on days 3 and 7 (P < 0.01). Serum TNF-a concentrations were not significantly affected by diet or environment. In conclusion, nursery pigs raised in clean environments had higher ADG and improved feed conversion than pigs reared in a dirty environment. Pigs fed diets containing ActiSaf HR+® tended towards increased ADG regardless of environment.

The influence of insect protein origins on broiler chicken meat parameters were studied using 135 day old Arbor acre birds subjected to three dietary treatments: Diet A comprised of a standard feed of the brand name ‘vital feed’ containing fishmeal as the major protein source (control), while Diet B and Diet C contained insect meal from African palm weevil larvae (Rhynchophorus phoenicis), respectively, winged termite (Macrotermes bellicosus) as replacement for fishmeal. Forty five broiler chicks were randomly assigned to each of the dietary treatments at the rate of fifteen chicks per replicate making three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were housed in similar cages and subjected to similar husbandry and sanitation practices, such that the only source of variation was the dietary treatments. After eight weeks of the experiment, carcass quality and organ weight measurements were analysed using appropriate statistical analysis. The result obtained showed that the broiler chickens fed insect meals performed significantly (P<0.05) better in terms of live weight gain (2,200.85±64.23 g and 2,046±58.40 g for Diet B and Diet C) compared to control. Carcass quality relating to defeathered weight and eviscerated weight also followed a similar trend with Diet B (2,187.74±62.72 g and 1,788.93±70.70 g), Diet C (2,015.83±74.62 g and 1,466.97±100.05 g), and Diet A (control; 1,526.47±47.40 g and 1,240.30±64.53 g). The records of cut-up parts and organ weight measurements were also significantly different (P<0.05) for the birds on insect meal (Diet B and Diet C) than those on fishmeal based diet (Diet A). The result showed that insect meal can effectively serve as a major source of protein in poultry feed formulation.
