Cardoon meal is a by-product of oil extraction from the seeds of Cynara cardunculus and can serve as a novel alternative feedstuff for ruminants. This study examined the rumen fermentation, biohydrogenation of fatty acids (FA) and microbial community in lambs fed a concentrate diet containing 15% dehydrated lucerne (CON, n = 8) or cardoon meal (CMD, n = 7) for 75 days pre-slaughter. Diets did not influence rumen fermentation characteristics and the abundance of bacteria, methanogens, fungi, or protozoa. Rumen digesta in CMD-fed lambs displayed a higher concentration of total saturated FA and lower total odd- and branched-chain FA and monounsaturated FA. Feeding CMD decreased total trans-18:1 isomer and the ratio of trans-10 to trans-11 C18:1, known as the “trans-10 shift”. Amplicon sequencing indicated that the rumen bacterial community in CMD-fed lambs had lower diversity and a higher relative phyla abundance of Proteobacteria at the expense of Bacteroidetes and Fibrobacteres. At the genus level, CMD mediated specific shifts from Prevotella, Alloprevotella, Solobacterium and Fibrobacter to Ruminobacter, suggesting that these genera may play important roles in biohydrogenation. Overall, these results demonstrate that cardoon meal can be used as a feedstuff for ruminants without negatively affecting rumen fermentation and microbiota but its impact on biohydrogenation may influence the FA composition in meat or milk.

Three experiments were conducted to evaluate the feasibility of using a commercial slow-release urea product (SRU; Optigen®, Alltech Inc., Nicholasville, KY, USA) as a partial replacement for vegetable protein sources in cattle diets. The first experiment was an in vitro rumen fermentation that evaluated the effect of replacing soybean meal (SBM) nitrogen with nitrogen from either SRU or free urea in diets varying in forage:concentrate ratios. The second experiment examined the effect of replacing SBM with SRU on in situ dry matter and nitrogen degradability in the rumen. In the third experiment, a feeding trial was conducted to evaluate the effect of replacing SBM (0% as-fed SRU) with 1% or 3% as-fed SRU on feed carbon footprint (CFP; total greenhouse gas emissions associated with the life cycle of feed raw materials) and the toxicity potential of SRU in growing beef cattle. Results showed that replacing SBM with SRU up to 1.3% did not negatively affect in vitro rumen fermentation parameters. Supplementing SRU favourably decreased ruminal accumulation of ammonia and lactic acid when compared to free urea. There was no significant effect on effective rumen degradability of dry matter and nitrogen when one-third of SBM was replaced by SRU in the in situ study. Compared with the 0% SRU diet, feed CFP decreased by 18% and 54% in 1% SRU and 3% SRU diets, respectively. Additionally, feeding up to 3% SRU diet to beef cattle did not affect health and intake, and blood hematological and biochemical indices were within the physiological range for healthy bulls, suggesting no indication of ammonia toxicity. Overall, these results indicate that SRU can be used as a sustainable alternative to partially replace vegetable protein sources in ruminant diets without compromising rumen function and health of ruminants.

Slow-release urea (SRU) is a coated non-protein nitrogen (NPN) source for providing rumen degradable protein in ruminant nutrition. A meta-analysis was conducted to evaluate the effects of replacing vegetable protein sources with SRU (Optigen®, Alltech Inc., USA) on the production performance of dairy cows. Additionally, the impact of SRU supplementation on dairy sustainability was examined by quantifying the carbon footprint (CFP) of feed use for milk production and manure nitrogen (N) excretion of dairy cows. Data on diet composition and performance variables were extracted from 17 experiments with 44 dietary comparisons (control vs. SRU). A linear mixed model and linear regression were applied to statistically analyse the effect of SRU on feed intake and production performance. Feeding SRU decreased (P < 0.05) dry matter intake (DMI, -500 g/d) and N intake (NI, -20 g/d). There was no significant effect (P > 0.05) on milk yield, fat-corrected milk, energy-corrected milk, and milk fat and protein composition. However, SRU supplementation improved (P < 0.05) feed efficiency (+3%) and N use efficiency (NUE, +4%). Regression analyses revealed that increasing SRU inclusion level decreased DMI and NI whereas increasing dietary crude protein (CP) increased both parameters. However, milk yield and feed efficiency increased in response to increasing levels of SRU inclusion and dietary CP. The NUE had a positive relationship with SRU level whereas NUE decreased with increasing dietary CP. The inclusion of SRU in dairy diets reduced the CFP of feed use for milk production (-14.5%; 373.13 vs. 319.15 g CO2 equivalent/kg milk). Moreover, feeding SRU decreased manure N excretion by 2.7% to 3.1% (-12 to -13 g/cow/d) and N excretion intensity by 3.6% to 4.0% (-0.50 to -0.53 g N/kg milk). In conclusion, feeding SRU can contribute to sustainable dairy production through improvement in production efficiency and reduction in environmental impacts.

BACKGROUND Concentrate supplementation of a grass silage‐based ration is a typical practice employed for indoor winter finishing of beef cattle in many temperate countries. Plant by‐products, such as dried corn gluten feed (CGF), can be used to replace conventional feedstuffs in a concentrate supplement to enhance the sustainability of ruminant production systems and to improve meat quality. This study examined the chemical composition, fatty acid profile, oxidative stability and sensory attributes of beef (longissimus thoracis muscle) from steers offered grass silage and concentrate supplements containing varying levels (0%, 25%, 50%, 75%) of CGF substituted for barley / soybean meal. RESULTS Feeding 50%CGF decreased the protein content and increased intramuscular fat in comparison with 25%CGF. Total phenol content and iron‐reducing antioxidant power followed the order: 0%CGF > 50%CGF and 25%CGF > 0%CGF = 50%CGF, respectively. Compared to 0%CGF, 25%CGF and 75%CGF decreased C14:0 and increased C22:2n‐6, C20:5n‐3 and total n‐3 polyunsaturated fatty acids whereas 75%CGF increased conjugated linoleic acids and C18:3n‐3. Diet did not affect the oxidative stability and sensory attributes of beef patties. CONCLUSION The inclusion of up to 75%CGF in a supplementary concentrate for steers increased the proportion of health‐promoting unsaturated fatty acids without negatively influencing the shelf‐life and eating quality of longissimus thoracis muscle. © 2021 Society of Chemical Industry

Thirty-six steers were randomly assigned to one of three dietary treatments fed ad libitum grass silage and concentrate supplements containing either barley/soybean meal (CON), 80% DM corn (CDGS)- or 80% DM wheat (WDGS)-dried distillers' grains with solubles for 124 days pre-slaughter. Chemical and fatty acid composition, shelf-life, and eating quality of longissimus thoracis muscle were determined. Dietary CDGS and WDGS increased the proportion of conjugated linoleic acids (P < 0.05) and tended to increase C18:3n-3 (P = 0.075) and total polyunsaturated fatty acids (P = 0.060) relative to the CON. Feeding diets containing distillers' grains reduced the lipid and colour stability of fresh beef patties stored in modified atmosphere packs (MAP), with CDGS exhibiting an intermediate effect between CON and WDGS. Diet did not negatively influence the texture profile parameters and eating quality attributes of beef stored in MAP. The inclusion of CDGS or WDGS in supplementary concentrates may improve the fatty acid profile but decreased the shelf-life of beef.

This study investigated the quality composition, oxidative stability and sensory attributes of beef (longissimus thoracis, LT) from steers offered grass silage and a concentrate supplement in which barley was replaced by 40% and 80% (as-fed basis) of dried citrus pulp (DCP). Dietary treatment did not influence the antioxidant status (α-tocopherol and total phenolic contents) and activities of LT (radical scavenging activity, ferric reducing antioxidant power and iron chelating activity). Feeding DCP significantly increased the proportion of conjugated linoleic acids and polyunsaturated fatty acids in beef. Lipid and colour stability of fresh beef patties stored in modified atmosphere packs (MAP) were unaffected by dietary treatment but feeding 40% DCP reduced (P < .05) lipid oxidation in aerobically-stored cooked beef patties. Beef patties stored in MAP for up to 7 days were assessed by sensory panellists to be juicier for those fed 40% DCP compared to 0% and 80% DCP. Results indicated that substitution of barley with DCP improved the fatty acid profiles of beef without negatively influencing the eating quality of beef.

Slow-release urea (SRU) is a coated non-protein nitrogen (NPN) source for ruminant nutrition. This study applied a meta-analytic technique to quantify the effect of a commercial SRU (Optigen®, Alltech Inc., Nicholasville, KY, USA) on the performance of beef cattle. Data were extracted from 17 experiments and analysed using the random-effects model to estimate the effect size of SRU on dry matter intake (DMI), crude protein intake (CPI), live weight gain (LWG) and feed efficiency (FE) of growing and finishing beef cattle. There was no effect of feeding SRU on the overall DMI and CPI of beef cattle. Dietary inclusion of SRU improved the overall LWG (+92 g/d/head) and FE (+12 g LWG/kg DMI/head) of beef cattle. Notably, SRU supplementation in growing cattle exhibited a better improvement on LWG (130 vs. 60 g/d/head) and FE (18 vs. 8 g LWG/kg DMI/head) compared with finishing cattle. Moreover, SRU showed consistent improvements on the LWG and FE of beef cattle under several study factors. Simulation analysis indicated that positive effects of SRU on LWG and FE improved profitability through reduction in feed cost and reduced the emission intensity of beef production. These results indicate that SRU is a sustainable NPN solution in beef cattle production.

Fatty acids and oxidative stability were determined in meat from lambs fed a diet containing 15% dehydrated alfalfa (CON, n = 8) or cardoon meal (CMD, n = 7). Furthermore, the antioxidant activity of a phenolic-rich cardoon meal extract (1.32 GAE mg/ml) was examined in muscle homogenates (0, 0.5, 1, 5% v/w) subjected to iron/ascorbate-induced oxidation. Feeding CMD did not affect lamb performances and carcass traits but reduced (P < 0.05) the vaccenic and rumenic acids and increased stearic acid in muscle. Lipid oxidation was higher in raw meat from the CMD-fed lambs after 7 days of storage (P < 0.05). Feeding CMD did not affect the colour stability of raw meat and the oxidative stability of cooked meat and of muscle homogenates incubated with pro-oxidant catalysts. Adding 5% cardoon extract in muscle homogenates increased (+114.3%; P = 0.03) the total phenolic content and reduced (−77.6%; P < 0.01) lipid oxidation, demonstrating the antioxidant potential of compounds present in cardoon meal.

Ruminant meat production is associated with a large environmental cost compared to other livestock products. Feed production, transport, and utilisation play a major role in global food security and greenhouse gas emissions from livestock production. Replacement of edible feed crops with human-inedible biomass in animal diets is a potential strategy that could reduce food-feed competition and mitigate the environmental impacts of livestock. Globally, plant by-products (PBP) represent an important human-inedible feed resource for livestock production. These waste streams can be obtained from agro-industrial processes such as distillery and biofuel production, oilseed processing, fruit and vegetable processing, sugar production, root and tuber processing, and herb, spice and tree processing. The microbial population in the forestomach (rumen) of ruminants allow PBP to be used effectively compared to monogastric livestock. Assessing and improving the utilisation of PBP may enhance the environmental sustainability of ruminant meat production without compromising the quality attributes and consumer acceptability of meat. Some PBP contain a considerable amount of residual bioactive compounds such as vitamins, unsaturated fatty acids, and phytochemicals. Feeding innovations based on the utilisation of bioactive-rich PBP may reduce enteric methane and nitrogen emissions in ruminants while improving the nutritional composition and shelf-life quality of meat and meat products. This review examines the dual-impact of dietary PBP on environmental sustainability and meat quality attributes in ruminant production. In addition, the paper highlights the implications of this alternative feeding strategy on meat safety and the strategic interventions pertinent to its practical application for ruminant meat production.

The chemical composition, fatty acid (FA) profile and antioxidant potential of beef from steers fed corn (CDG) or wheat (WDG) dried distillers’ grains were determined. Thirty-six Charolais and Limousin-sired steers (421.9 ± 38.9 kg) were blocked by breed and body weight and randomly assigned to one of three dietary treatments (n = 12 steers/treatment). Treatments consisted of ad libitum grass silage supplemented with concentrate ration (4.0 kg dry matter basis daily) containing either barley/soybean meal (control), 80% CDG or 80% WDG (as-fed basis) fed for 124 days pre-slaughter. Following slaughter, the longissimus thoracis muscle (LT) was excised at 48 h post-mortem, vacuum packaged and aged for 14 days prior to subsequent analysis. Feeding CDG increased (P < 0.05) the pH and decreased the ash content of LT relative to the control. Dietary CDG (P < 0.05) increased the protein content of LT compared to WDG. The proportion of C14:0 (P < 0.05) was lower in LT from steers fed WDG relative to the control whereas the percentage of C15:0 and C20:0 (P < 0.01) were greater in LT from WDG compared to the control. Both CDG and WDG increased (P < 0.05) the percentage of conjugated linoleic acids (c-9 t-11+t-9 c-11 18:2) and tended to increase the percentage of α-linolenic acid (P= 0.08), C22:2 n-6 (P = 0.05) and polyunsaturated FA (PUFA, P = 0.06) compared to the control. There was no treatment effect (P > 0.05) on antioxidant status (total phenol and α-tocopherol contents) or activity (radical scavenging and iron-chelating activities, and iron-reducing antioxidant power) of LT. In addition, dietary CDG or WDG did not influence lipid or oxymyoglobin oxidation in muscle homogenates incubated with iron/ascorbate pro-oxidants. Overall, the inclusion of distillers’ grains in supplementary concentrates may improve the FA composition of beef irrespective of distillers’ grains type.

The proximate composition, fatty acid (FA) profile and antioxidant capacity of beef from steers fed varying inclusion levels of dried corn gluten feed (CGF) were examined. Forty-eight Charolais and Limousin-sired steers (424.0 ± 39.0 kg), blocked by breed and body weight, were randomly assigned to one of four concentrate rations (n = 12 steers/treatment, 4.0 kg dry matter basis daily) offered as a supplement to grass silage fed ad libitum for 124 days pre-slaughter. Concentrate rations contained either 0% CGF (control, barley/soybean meal-based ration), 25% CGF, 50% CGF or 75% CGF. Following slaughter, longissimus thoracis muscles (LT) were excised at 48 h post-mortem, vacuum packaged and aged for 14 days prior to further analysis. Diets containing 25% and 75% CGF increased the pH (~ 5.47 to 5.53) of LT compared to control whereas 50% CGF decreased the protein content and increased intramuscular fat of LT compared to 25% CGF. In comparison to the control, 25% and 75% CGF decreased C14:0 and increased long-chain polyunsaturated FA (PUFA, C22:2 n-6 and C20:5 n-3) and total n-3 PUFA (P < 0.01) whereas 75% CGF increased (P< 0.05) conjugated linoleic acids (c-9 t-11+t-9 c-11 18:2) and α-linolenic acid. No treatment effect on the antioxidant status (α-tocopherol content, radical scavenging and iron-chelating activities) of LT was observed. However, the total phenol content and iron-reducing antioxidant power in LT followed the order: control > 50% CGF (P < 0.05) and 25% CGF > control = 50% CGF (P < 0.01), respectively. Lipid and oxymyoglobin oxidation were unaffected by dietary treatment when muscle homogenates were subjected to iron/ascorbate-induced oxidation for up to 4 h at 4 ºC. Overall, results demonstrated that replacement of barley/soybean meal with up to 75% CGF in supplementary concentrate diets of steers increased health-promoting unsaturated FA in beef without negatively influencing the susceptibility of beef to oxidative deterioration.

This study characterised the response of ruminal fermentation and the rumen microbiome in lambs fed commercial vegetal sources of hydrolysable tannins (HT) and condensed tannins (CT). Forty-four lambs (19.56 ± 2.06 kg) were randomly assigned to either a concentrate diet (CON, n = 8) or CON supplemented with 4% of two HT [chestnut (Castanea sativa, HT-c) and tara (Caesalpinia spinosa, HT-t)] and CT [mimosa (Acacia negra, CT-m) and gambier (Uncaria gambir, CT-g)] extracts (all, n = 9) for 75 days pre-slaughter. Tannin supplementation did not influence ruminal fermentation traits. Quantitative PCR demonstrated that tannins did not affect the absolute abundance of ruminal bacteria or fungi. However, CT-m (−12.8%) and CT-g (−11.5%) significantly reduced the abundance of methanogens, while HT-t (−20.7%) and CT-g (−20.8%) inhibited protozoal abundance. Ribosomal amplicon sequencing revealed that tannins caused changes in the phylogenetic structure of the bacterial and methanogen communities. Tannins inhibited the fibrolytic bacterium, Fibrobacter and tended to suppress the methanogen genus, Methanosphaera. Results demonstrated that both HT and CT sources could impact the ruminal microbiome when supplemented at 4% inclusion level. HT-t, CT-m and CT-g extracts displayed specific antimicrobial activity against methanogens and protozoa without compromising ruminal fermentation in a long-term feeding trial.

The hypothesis was tested that butyrate presence in the digesta of distinct gastrointestinal tract (GIT) segments of broilers leads to differential effects on digesta retention time, gut morphology, and proteolytic enzymatic activities, ultimately resulting in differences in protein digestibility. A total of 320 male day-old Ross 308 broilers were randomly assigned to 5 dietary treatments: 1) control (no butyrate), 2) unprotected butyrate (main activity in the crop and gastric regions), 3) tributyrin (main activity in the small intestine), 4) fat-coated butyrate (activity in the whole GIT) and 5) unprotected butyrate combined with tributyrin, each replicated 8 times. Rapeseed meal was used in combination with a fine dietary particle size in order to challenge the digestive capacity of young broilers. Birds were dissected at 22, 23, and 24 d of age and samples of digesta at various GIT locations as well as tissues were collected. Butyrate concentration varied significantly across GIT segments depending on treatment, indicating that the dietary contrasts were successful. The apparent ileal digestibility of methionine tended to increase when butyrate and/or propionate was present in colonic and cecal contents, possibly due to modifications of GIT development and digesta transit time. Butyrate presence in the digesta of the crop, proventriculus and gizzard, on the contrary, decreased the apparent ileal digestibility of several amino acids (AA). In addition, butyrate presence beyond the gizzard elicited anorexic effect that might be attributable to changes in intestinal enteroendocrine L-cells secretory activities. The present study demonstrates that, in broilers, effects of butyrate on digestive processes are conditioned by the GIT segment wherein the molecule is present and indicates its influence on digestive function and bioavailability of AA.

The pivotal roles of regulatory jurisdictions in the feed additive sector cannot be over-emphasized. In the European Union (EU), antioxidant substances are authorized as feed additives for prolonging the shelf life of feedstuffs based on their effect for preventing lipid peroxidation. However, the efficacy of antioxidants transcends their functional use as technological additives in animal feeds. Promising research results have revealed the in vivo efficacy of dietary antioxidants for combating oxidative stress in production animals. The in vivo effect of antioxidants is significant for enhancing animal health and welfare. Similarly, postmortem effect of dietary antioxidants has been demonstrated to improve the nutritional, organoleptic and shelf-life qualities of animal products. In practice, dietary antioxidants have been traditionally used by farmers for these benefits in livestock production. However, some antioxidants particularly when supplemented in excess could act as prooxidants and exert detrimental effects on animal well-being and product quality. Presently, there is no exclusive legislation in the EU to justify the authorization of antioxidant products for these in vivo and postmortem efficacy claims. To indicate these efficacy claims and appropriate dosage on product labels, it is important to broaden the authorization status of antioxidants through the appraisal of existing EU legislations on feed additives. Such regulatory review will have major impact on the legislative categorization of antioxidants and the efficacy assessment in the technical dossier application. The present review harnesses the scientific investigations of these efficacy claims in production animals and, proposes potential categorization and appraisal of in vivo methodologies for efficacy assessment of antioxidants. This review further elucidates the implication of such regulatory review on the practical application of antioxidants as feed additives in livestock production. Effecting these regulatory changes will stimulate the innovation of more potent antioxidant products and create potential new markets that will have profound economic impacts on the feed additive industry. Based on the in vivo efficacy claims, antioxidants may have to contend with the legislative controversy of either to be considered as veterinary drugs or feed additives. In this scenario, antioxidants are not intended to diagnose or cure diseases as ascribed to veterinary products. This twisted distinction can be logically debated with reference to the stipulated status of feed additives in Commission Regulation (EC) No 1831/2003. Nonetheless, it is imperative for relevant stakeholders in the feed additive industry to lobby for the review of existing EU legislations for authorization of antioxidants for these efficacy claims.

Several production factors could exacerbate the biological formation of free radicals which, in turn, cause oxidative stress that impair the health, overall performance and meat quality of broiler chickens. Such factors could have a nutritional, pathological, physiological or environmental origin. The modern drive towards intensive commercial poultry production has elevated the exposure risk of broilers to these factors. In contrast, it has been demonstrated in many studies that dietary antioxidants could combat oxidative stress and improve broiler performance as well as meat quality. Interestingly, these efficacy claims have generated much attention from several feed additive companies which has spurred the development of certain commercial antioxidant products available in the global market. Information from recent studies suggests that both natural and synthetic antioxidants can be effective for augmenting broiler performance and meat quality particularly under conditions of oxidative stress. However, legislative restrictions may hinder the inclusion of high amounts of synthetic antioxidants required to achieve potency in oxidative-stressed broilers. The efficacy of dietary antioxidants depends on the age of the birds, dose and duration of supplementation. Moreover, supplementation of individual antioxidants on average seems to offer a better performance improvement than does a combination of antioxidants. Nonetheless, research efforts aimed at finding the right proportion of combining dietary antioxidants will offer tremendous economic benefits especially with the reduced use of costly synthetic vitamin E. This article gives further insights into research areas that could enhance the effective supplementation of antioxidants in broilers.
