Abstract We investigated the effects of feeding beet pulp (BP) instead of corn flake (CF) on growth performance, beef quality, ruminal fermentation, and blood parameters in Korean cattle steers. Eighteen Korean cattle steers (body weight, 732 ± 12.6 kg; age, 31.2 ± 0.16 months) were divided into the CF and BP groups. The approximately 92% of dry matter of the requirement was offered as a concentrate portion, and the 8% was offered as an oat straw. The 85% of concentrate portion was provided by the pelleted basal concentrate, and the remaining 15% with CF or BP for 12 weeks. Average daily gain, feed efficiency, and carcass traits were not affected by feeding BP. The proportion of ruminal iso-butyrate (P = 0.004), iso-valerate (P = 0.001), and valerate (P = 0.01) were lower in the BP group compared to the CF group. Blood glucose (P = 0.06) and non-esterified fatty acids (P = 0.09) concentrations tended to be higher in the BP group than in the CF group. The results suggest that BP could be a good energy source without affecting the growth performance and beef quality in Korean cattle steers.

AbstractWhole-crop maize forage was ensiled without inoculant (control), inoculated with Lactobacillus buchneri and L. plantarum at a rate of 1 × 105 cfu/g fresh forage per bacterium (LBLP), or inoculated with Bacillus subtilis and L. plantarum at a rate 1 × 105 cfu/g fresh forage per bacterium (BSLP) with the goal to investigate the growth performance of finishing feedlot lambs. Thirty Dorper × Santa Ines lambs (29 ± 3.5 kg initial body weight) were used in the feedlot programme and assigned (n = 10) to one of three diets containing control, LBLP or BSLP silages in a 60:40 forage:concentrate ratio. Inoculation of maize silage did not alter dry matter intake (overall mean = 1.16 kg/day) and average daily gain (overall mean = 0.217 kg/day) of lambs. Consequently, feed efficiency remained unchanged. Inoculation of maize silage did not alter carcass and meat traits of lambs, with the exception of meat colour, wherein yellowness (b*) decreased by feeding LBLP and BSLP diets compared with the untreated diet. Regarding ruminal fermentation, there was an interaction between diets and the interval at which ruminal fluid was sampled for determining total volatile fatty acid concentration, but inoculation yielded no obvious results. In conclusion, the use of diets based on maize silage inoculated with L. plantarum combined with either L. buchneri or B. subtilis did not display relevant effects on growth performance of lambs; this response might be related to the limited impact of these bacterial inoculants on silage composition.

(1) Background: we investigated the influence of dietary soybean meal (SBM) replaced with distillers dried grains with solubles (DDGS) plus rumen-protected (RP) lysine and methionine on the growth performance, nutrients digestion, rumen fermentation, and serum parameters of Hu sheep. (2) Methods: ninety Hu sheep were allocated to five groups: the control group (CON) which received the SBM diet, the DDGS group (NSM), the DDGS diet with RP lysine group (DRPL), the DDGS diet with RP methionine group (DRPM), and the DDGS diet with a mixture of RP lysine and methionine group (DRPLM). (3) Results: Final BW and carcass weight of the DRPLM and CON groups were greater (p ≤ 0.05) compared to NSM, DRPL, and DRPM groups. The DRPLM group tended to increase the dry matter intake (DMI, p = 0.06), average daily gain (ADG, p = 0.06), dressing percentage (p = 0.07), and tail fat weight (p = 0.09). The DRPLM group had increased (p ≤ 0.05) apparent digestibility and had altered ruminal fermentation characteristics. (4) Conclusions: replacement of SBM with DDGS in a diet with adequate metabolizable protein and by-pass amino acids (lysine and methionine) could maintain the growth performance of Hu sheep.

The objective of the present study was to evaluate the effect of different levels of ground oak acorn on growth performance, blood parameters and carcass characteristics. Twenty-four goat kids averaging 16.93 ± 1.25 kg initial bodyweight were randomly assigned to four experimental diets in a completely randomised design for 90 days. The experimental diets consisted of (1) 0% oak acorn (control), (2) 8% oak acorn, (3) 17% oak acorn and (4) 25% oak acorn on a DM basis. The goats were slaughtered after 105 days of feeding and carcass characteristics were measured. DM intake increased linearly in small amounts as the level of acorn in the diet increased (P < 0.004). The results showed that average daily gain, water intake and feed conversion ratio were unaffected by levels of ground oak acorn (P > 0.05). There were no significant differences in blood parameters (P > 0.05). Carcass fat depth and abdominal fat weight decreased with increasing ground oak acorn in the diet. Other carcass characteristics were not affected by different levels of ground oak acorn. On the basis of the results of the present study, it may be concluded that ground oak acorn can be used up to 25% in the diets of young goats without any adverse effects on growth performance and carcass characteristics. At this level of acorns, the goats received low concentrations of hydrolysable tannins (11 g/kg DM) in their diet.

Two growth performance trials were conducted to evaluate the effects of grain source (corn vs. barley), corn silage level (15 vs. 50%) and body weight (BW) at slaughter on growth performance, carcass characteristics, and beef quality. Gains were greater ( P < 0.01) feeding corn vs. barley to Angus cattle slaughtered at 550 or 600 kg, most likely due to greater (P < 0.02) feed intakes for corn-fed cattle. Despite greater dry matter intake (DMI; P < 0.01) and feed to gain ratios (P < 0.08) with 50% silage diets, cost of production was lower (P < 0.01) feeding 50 vs. 15% silage diets. Grain source by BW endpoint interactions (P < 0.06) were present for Angus steers due to greater average daily gain (ADG) and lower feed to gain and cost of production in corn-fed cattle slaughtered at 600 versus 550 kg, while the converse was the case for barley-fed cattle. Carcass characteristics and palatability attributes were generally not affected (P > 0.05) by grain source or silage level in the diet. Grain source by silage level by slaughter endpoint interactions (P < 0.08) were present for measures of tenderness (shear force and taste panel assessment of tenderness, chewiness, and rate of breakdown). Gains were not affected (P > 0.27) by grain source for Charolais cattle, while barley feeding decreased (P < 0.10) DMI, feed to gain, and costs of production versus corn feeding. Silage level in the diet did not affect (P > 0.10) any growth performance trait in Charolais cattle. Grain source generally did not affect (P > 0.10) most carcass characteristics and shear force with the Charolais steers. The feeding of the 15% silage diet decreased (P < 0.10) measures of leanness and muscling. Many carcass characteristics were affected (P < 0.02) by slaughter endpoint in Charolais steers, with values changing as BW at slaughter increased from 600 to 700 kg.

The objective of this study was to evaluate the effect of supplementation of monensin, yeast and glucogenic precursors on growth performance and digestive characteristics of feedlot beef cattle. The treatments evaluated were: control, monensin (40 mg/kg DM), S. cerevisiae (10 g/a/d) and a mix of 1,2-propanediol and calcium propionate as glucogenic precursors (20 g/a/d) as D1, D2, D3 and D4, respectively. In trial 1, eighty steers (261±8 kg) were evaluated for 120d for growth performance variables. Thus, supplementation increased the average daily gain, feed efficiency and final weight (P less than 0.05). In Trial 2, four steers (260±5 kg) were used to evaluate ruminal fermentation and total digestive parameters. The ruminal propionate concentrations and the flow of nitrogen to duodenum increased with supplementation (P less than 0.05) whereas the ruminal digestion of nitrogen decreased with supplementation (P less than 0.05). It is concluded that productive parameters and propionate production are higher when supplementing with 10 g/a/d of S. cerevisiae and 20 g/a/d of the glucogenic precursor which presented a lower ruminal protein degradation.

Abstract This experiment evaluated the effects of substituting corn with beet pulp (BP) on growth performance and ruminal fermentation characteristics and microbiomes in fattening steers. Twelve Korean cattle steers (body weight, 485 ± 19 kg; age, 18.0 ± 0.17 months) were divided into corn and BP groups. Both groups were fed the basal concentrate to meet 80% of the nutrient requirements. For the corn group, corn (dry matter) was supplemented for the remaining 20% of requirement by top dressing; the BP group was supplemented with 14.88% BP plus 1.92% fat to provide the iso-energy content as the corn group. Steers were fed oat grass (2 kg as-fed basis) daily. Body weight was measured, and rumen fluid was collected after 3 h of feeding using oral stomach tube methods: at the start of the experiment then at 4-week intervals. Feed intake, average daily gain, and gain-to-feed ratio were not (P &gt; 0.05) affected by BP substitution; nor were acetate, propionate, butyrate, or total volatile fatty acid concentrations in the rumen fluid (P &gt; 0.05). BP substitution increased (P &lt; 0.05) the acetate to propionate ratio at 4, 8, and 12 weeks. Genomic DNA was extracted from pellets of rumen contents, and microbial populations were measured using real-time PCR at 8 and 12 weeks. BP substitution increased relative abundances of cellulolytic bacteria including Fibrobacter succinogenes (P = 0.01) and Ruminococcus albus (P = 0.04) at 12 weeks, whereas it did not affect amylolytic bacteria, including Succinimonas amylolytica, Ruminobacter amylophilus, and Streptococcus bovis. At 8 weeks, none of the microbial populations were altered by BP substitution. In conclusion, BP could provide a good energy source substitute for corn without affecting growth performance in the fattening period of beef cattle. Increased relative abundances of several cellulolytic bacteria supported the increased ruminal acetate to propionate ratio.

Low Energy Diet

Forty-eight Hereford and 60 Simmental steers were used to evaluate breed differences as affected by dietary energy content on growth performance, carcass and chemical composition, and beef quality. Diets were based on corn silage, alfalfa haylage, whole corn, and SBM and were formulated to provide 2.52 to 2.81 Mcal kg−1 ME and 11.7 to 12.6% protein in the growing phase and 2.69 to 2.86 Mcal kg−1 ME and 9.7 to 10.4% protein in the finishing phase. Low- and high-ener-gy diets were formulated for each breed with the high-energy diet for Hereford serving as the low-energy diet for Simmental. Steers were slaughtered after attaining 8 to 10 mm backfat determined by ultrasound. Higher energy diets increased (P < 0.09) average daily gain (ADG) and feed efficiency within both breeds. Hereford gained more rapidly (P = 0.074) and were more (P = 0.001) efficient in converting feed to gain than Simmental. High-energy diets decreased (P = 0.001) days on feed for both breeds and increased (P = 0.001) carcass weights for Simmental. Otherwise, carcass and chemical composition were generally unaffected by dietary energy content. Simmental were heavier (P = 0.001) and leaner (P = 0.001) than Hereford while marbling classification and intramuscular fat content were similar (P > 0.10) between breeds. While shear force decreased (P = 0.043) feeding the low-energy diet to Simmental, other shear and palatability attributes were unaffected by dietary energy content or breed. Altering dietary energy content for Hereford and Simmental influenced growth performance without affecting carcass and chemical composition and beef quality.

Effect Of Feeding

Fumonisin contamination in corn is an emerging issue in animal feed production. Fumonisin disrupts the metabolism of sphingolipids and reduces growth performance. This experiment was conducted to determine the effect of feeding fumonisin-contaminated corn on growth performance and sphinganine (SA) to sphingosine (SO) ratios of 9 to 28 kg pigs. A total of 350 pigs, were used with 5 pigs/pen and 14 pens/treatment. Dietary treatments contained fumonisin-contaminated corn (50 mg/kg of fumonisin B1 + B2) blended with low fumonisin corn (10 mg/kg of fumonisin B1 + B2) to provide dietary fumonisin concentrations of 7.2, 14.7, 21.9, 32.7, and 35.1 mg/kg. From day 0 to 28, increasing fumonisin concentration decreased (linear, p < 0.001) average daily gain, average daily feed intake (linear, p = 0.055), and gain:feed ratio (linear, p = 0.016). Although these response criteria tested linear, the greatest reduction in performance was in pigs fed with 32.7 and 35.1 mg/kg of fumonisin (B1 + B2). Increasing fumonisin concentration increased the serum SA:SO ratio (linear, p < 0.001) on day 14 and 28. In summary, for 9 to 28 kg nursery pigs, increasing fumonisin linearly decreased average daily gain and gain:feed ratio. However, despite the linear response, diets containing up to 21.9 mg/kg of fumonisin did not have as dramatic a decrease in growth performance as those fed more than 32.7 mg/kg. Further research is warranted to determine the effect of fumonisin concentrations between 21.9 and 32.7 mg/kg.

The aim of this study was to evaluate the effect of zinc (Zn) supplementation in different commercial forms on the growth performance, health status, and Zn balance of weaners in field conditions. The animals were fed pre-starter (from the 28th to 47th day of life) and starter (from the 48th to 74th day of life) mixtures differing in Zn form and concentration. Group I was given ZnSO4 at 150 mg kg−1; Group II received pre-starter zinc oxide (ZnO) at 3000 mg kg−1 and starter at 150 mg kg−1; and Group III was given 150 mg kg−1 of zinc oxide nanoparticles (nZnO). We found that the average daily gain in Group I was significantly lower, compared to Groups II and III. A commonly accepted level of Zn (150 mg kg−1) as nZnO can be recommended, instead of therapeutic doses of Zn preparations with the same efficiency. Moreover, a lower level of Zn in the diet can prevent the excessive accumulation of this element in waste and, thus, reduce environmental damage.

SUMMARYA total of 70 Nellore bulls (18 ± 3 months of age) were used to determine the effects of crude glycerine (CG) replacing starch- v. fibre-based energy ingredients in low (LC; 0·40 concentrate) or high concentrate (HC; 0·60 concentrate) – on a dry matter (DM) basis – on DM intake (DMI), methane emissions and growth. Ten bulls were slaughtered (reference group) to obtain the carcass gain (CrG). The 60 remaining bulls (374 ± 24·5 kg) were allocated to a 2 × 3 factorial arrangement (two concentrate levels, LC or HC; and three feeding regimes, FR). The FR were: CO – without CG and maize as an ingredient of concentrate; CGM – inclusion of CG (0·10 of DM) replacing maize in the concentrate; and CGSH – inclusion of CG (0·10 of DM) replacing soybean hulls (SH) in the concentrate. Bulls fed LC or HC had similar DMI (kg/d) and growth. The DMI and average daily gain (ADG) were similar among FR. Concentrate level and FR tended to interact for methane emissions (g) per kg DMI. Bulls fed CGM had a greater G : F (g CrG/kg DMI) than those fed CO or CGSH diets. Increasing dietary concentrate (0·40–0·60) did not affect intake, methane emissions, or growth. Inclusion of CG in diets to replace SH in LC diets tended to decrease methane emissions from animals. When CG replaces SH in the diets, CrG and G:F (g CrG/kg DMI) are decreased compared with bulls fed CGM.
