An experiment was conducted to investigate the effects of glutamine on growth performance of weanling piglets. Sixty piglets weaned at 21 days of age were randomly assigned to two groups (10 piglets per pen, 3 pens per group). The control group received a maize-soybean meal-based diet. The treatment group received a maize-soybean meal-based diet supplemented with 1.0% free l-glutamine. Piglets were fed the diets for 20 days. Results showed that piglets fed the glutamine diet had lower diarrhoea ratio and shorter diarrhoea duration than those fed the control diet during 20 days after weaning. During the first ten days after weaning, pigs supplemented with glutamine had a 12.05% lower feed:gain ratio than those fed the control diet (P &lt; 0.05). During the second ten days after weaning, they had a 27.75% higher average daily gain than those fed the control diet (P &lt; 0.05); there were no differences in the feed:gain ratio and average daily feed intake. During the first ten days after weaning, the serum urea nitrogen of pigs supplemented with glutamine was reduced by 17.36% (P &gt; 0.05) compared to the control. During the second ten days after weaning, serum urea nitrogen was reduced by 4.27% and serum concentrations of total protein increased by 18.70% in pigs supplemented with glutamine compared to the control (P &gt; 0.05). There were no differences in albumin, T<sub>3,</sub> T<sub>4</sub> and growth hormone. &nbsp;

(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.

SUMMARYThe present study was conducted to determine the effects of a polysaccharide of Atractylodes macrophala Koidz (PAM) as a dietary additive on growth performance, immunoglobulin concentration and IL-1β expression in weaned piglets. One hundred and twenty Landrace×Yorkshire piglets weaned at 28 days old (body weight 7·5±0·07 kg) were assigned to five treatment groups (three pens/group, eight piglets/pen) fed maize/soybean-based diets supplemented with 0, 3, 6 or 9 g of PAM/kg diet or antibiotics (0·4 g flavomycin/kg+0·13 g olaquindox/kg). The experimental period was 28 days. With increasing PAM supplementation levels, average daily gain was greater (quadratic, P<0·05) and the ratio of amount fed to live weight (LW) gain (feed/gain) improved (quadratic, P<0·05) during days 14–28 and overall, and diarrhoea incidence decreased (linear, P<0·05) during days 14–28. Supplementation of PAM also increased (quadratic, P<0·05) serum concentrations of interleukin (IL)-2 and IL-6 on day 14, and increased (quadratic, P<0·05) IL-1β expression in jejunal mucosa and lymph nodes. Concentrations of PAM between 6 and 9 g/kg presented the strongest bioactivity compared to the control group or antibiotic-fed group. These findings indicate that PAM is effective in improving growth performance and cytokine response, which suggests that PAM can be used as a diet additive for weanling piglets.

The objective of this study was to determine the effects of chlorogenic acid (CA) and bamboo charcoal particles activated by microwave (BCP) on performance, serum urea nitrogen and husbandry environment of broilers. The diets were devoid of antibiotic growth promoters (AGP). Two hundred and forty Avian broilers were allocated to a 2 × 2 factorial experiment involving two levels of CA (0 or 1000 mg CA/kg feed), and two levels of BCP supplementation (0 or 100 mg/kg feed). The diets and water were offered ad libitum. The growth performance and serum urea nitrogen was significantly increased when CA supplemented (P<0.05), while BCP significantly affects the ammonia concentration of the husbandry environment (P<0.05). These results indicate that CA and BCP combination can effectively improve the performance and husbandry environment.

Abstract Background Garlic and its constituents exhibit activities on modifying rumen fermentation and improving growth performance. As a by-product of garlic processing, garlic skin contains similar bioactive components as garlic bulb. However, studies in ruminants using garlic skin are scarce. This study was conducted to investigate the effects of garlic skin supplementation on rumen fermentation characterizes, growth performance, ruminal microbes and metabolites in ruminants. Twelve Hu lambs were randomly assigned into one of two treatments: basal diet (CON) or basal diet supplemented with 80 g/kg DM of gallic skin (GAS). The experiment lasted for10 weeks, with the first 2 weeks for adaptation. Results The results revealed that the average daily gain and volatile fatty acid concentration were higher (P < 0.05) in lambs fed GAS than that in the control group. Garlic skin supplementation did not significantly (P > 0.10) affect the α-diversity indices. Increased (P < 0.05) abundances of Prevotella, Bulleidia, Howardella, Methanosphaera but a decreased (P < 0.05) abundance of Fretibacterium were observed in GAS-fed lambs. In addition, the garlic skin supplementation favorably regulated (P < 0.05) pyrimidine metabolism, purine metabolism, vitamin B6 and B1 metabolism. Moreover, high correlations were observed between fluctuant rumen microbiota and metabolites. Conclusions Supplementation of garlic skin improved the growth performance of sheep by modifying rumen fermentation through inducing shifts in the rumen microbiome and metabolome.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

A total of 120 weanling pigs [(Landrace &times; Yorkshire) &times; Duroc], 21 days of age with an average initial body weight (BW) of 6.52 &plusmn; 0.22 (SE) kg were selected to investigate the effects of extruded rice product as a replacement for dried whey on growth performance, coefficient of total tract apparent digestibility (CATTD), blood profiles, faecal shedding of Lactobacillus and Escherichia coli (the microbial counts of digesta were expressed as log<sub>10</sub> colony forming units per gram), and faecal scores of weanling pigs. Pigs were randomly allocated to one of four dietary treatments, with six replicates per treatment and five pigs per pen. Pigs in the control group were fed a diet based on corn, soybean, and 20% dried whey. Experimental groups received the same diet as the control group, but dried whey was replaced by 3%, 6%, and 9% extruded rice. Throughout the experimental period (six weeks), no differences were observed in the average daily gain, average daily feed intake, and gain/feed ratio. Pigs fed 6% and 9% extruded rice had a lower (P &lt; 0.05) CATTD than pigs fed the control diet on Day 14. The blood creatinine concentration of pigs fed 9% extruded rice was higher (P &lt; 0.05) than that of pigs in the control group on Day 14. Pigs fed the diets containing 6% and 9% extruded rice had decreased (P &lt; 0.05) faecal E. coli counts on Day 14 compared with pigs fed the control diet. The current results indicate that feeding extruded rice can decrease faecal E. coli counts without negative effects on growth performance in weanling pigs.

Abstract Cecal inoculum collected from broilers fed a diet supplemented with xylanase showed increased gas production in an in vitro fermentation study with arabinoxylan-based substrates, indicating that intestinal microbiota can adapt to increase the capability to ferment arabinoxylans when pre-exposed to xylo-oligosaccharides (XOS) produced by xylanase. As the most abundant non-starch polysaccharides in a corn-soybean meal-based diet is arabinoxylan, this study tested the hypothesis that a blend of a xylanase and XOS will improve growth performance of pigs compared with those fed a diet supplemented with xylanase alone. One hundred twenty male crossbred (Landrace x Large white x Duroc) pigs (77 days average age; 30 kg average body weight -BW) were allocated to one of three treatments: CTR (control diet), XYL (CTR diet supplemented with 100 g/t of xylanase [Econase XT, AB Vista]) and XYL+XOS [CTR diet supplemented with 100 g/t of xylanase and XOS (Signis, AB Vista)]. Each treatment had ten replicates, with 4 animals each. The control diet was formulated with corn, soybean meal, DDGS and cassava meal as major ingredients. Pelleted diets were fed over 3 phases: grower (30–60 kg), finisher 1 (60–80 kg) and finisher 2 (80–100 kg). Average daily gain (ADG) and daily feed intake (ADFI) were measured from 30 to 100 kg and feed efficiency calculated (FCR). No treatment effects were observed on ADFI. Pigs offered the XYL+XOS had increased ADG (CTR = 1.058 vs XYL+XOS= 1.086 g/pig/d; P = 0.02) compared with those supplemented with xylanase alone (CTR = 1.058 vs XYL = 1.067 g/pig/d; P = 0.40). Feed efficiency was improved with XYL (2.65; P = 0.042) and XYL+XOS (2.60; P < 0.001) compared with CTR (2.71). These results suggest that xylanase in combination with XOS further improves daily gain and FCR compared with a xylanase alone. Interestingly the differences between XYL and XYL+XOS become more apparent in older animals, when the microbiome matures and possibly digests fiber more effectively.

Abstract This study investigated the different addition levels of iron (Fe) in growing-finishing pigs and the effect of different Fe levels on growth performance, hematological status, intestinal barrier function, and intestinal digestion. A total of 1,200 barrows and gilts ([Large White × Landrace] × Duroc) with average initial body weight (BW; 27.74 ± 0.28 kg) were housed in 40 pens of 30 pigs per pen (gilts and barrows in half), blocked by BW and gender, and fed five experimental diets (eight replicate pens per diet). The five experimental diets were control diet (basal diet with no FeSO4 supplementation), and the basal diet being supplemented with 150, 300, 450, or 600 mg/kg Fe as FeSO4 diets. The trial lasted for 100 d and was divided into the growing phase (27 to 60 kg of BW) for the first 50 d and the finishing phase (61 to 100 kg of BW) for the last 50 d. The basal diet was formulated with an Fe-free trace mineral premix and contained 203.36 mg/kg total dietary Fe in the growing phase and 216.71 mg/kg in the finishing phase based on ingredient contributions. And at the end of the experiment, eight pigs (four barrows and four gilts) were randomly selected from each treatment (selected one pig per pen) for digesta, blood, and intestinal samples collection. The results showed that the average daily feed intake (P = 0.025), average daily gain (P = 0.020), and BW (P = 0.019) increased linearly in the finishing phase of pigs fed with the diets containing Fe. On the other hand, supplementation with different Fe levels in the diet significantly increased serum iron and transferrin saturation concentrations (P &lt; 0.05), goblet cell numbers of duodenal villous (P &lt; 0.001), and MUC4 mRNA expression (P &lt; 0.05). The apparent ileal digestibility (AID) of amino acids (AA) for pigs in the 450 and 600 mg/kg Fe groups was greater (P &lt; 0.05) than for pigs in the control group. In conclusion, dietary supplementation with 450 to 600 mg/kg Fe improved the growth performance of pigs by changing hematological status and by enhancing intestinal goblet cell differentiation and AID of AA.

Aim: This study aimed to investigate effects of rations containing formaldehyde-protected soybean meal on meat production in Kacang goats. Materials and Methods: Fourteen yearling Kacang bucks, weighing 15.8-19.8 kg, were arranged in a completely randomized design. The treatments included a control (PSBM0): 100% untreated SBM; PSBM50: 50% untreated SBM + 50% formaldehyde-protected SBM; and PSBM100: 100% formaldehyde-protected SBM. Results: The goats disliked the protected SBM. Therefore, differences in their intakes were reflected in their average daily gain (ADG). The ADG and slaughtered weight of the control group were the highest, while those of the PSBM100 and PSBM50 groups were similar. The carcass weights and meat production of the control group were higher than those of the PSBM50 group, but the retained protein to the meat conversion ratio of the PSBM50 group was lower than that of the control. The carcass percentages were similar between the treatments. Conclusion: The retained protein to meat conversion ratio of Kacang goats fed with 50% formaldehyde-protected SBM showed the lowest value, indicating that these rations efficiently produced meat in the carcass.
