Replacing Soybean Meal with Distillers Dried Grains with Solubles plus Rumen-Protected Lysine and Methionine: Effects on Growth Performance, Nutrients Digestion, Rumen Fermentation, and Serum Parameters in Hu Sheep

(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.

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.

Abstract Background: The use of antibiotics as supplements in animal feed is restricted due to possible health hazards associated with them. Consequently, there is increasing interest in exploiting natural products as antibiotics with no detrimental side effects. In this study, we examined the effect of Astragalus membranaceus root (AMT) supplementation on dry matter intake, growth performance, rumen fermentation and immunity of Tibetan sheep. Materials and methods: Twenty-four male Tibetan sheep (31 ± 1.4 kg; 9 months old) were assigned randomly to one of four dietary treatments with different levels of AMT: 0 g/kg, 20 g/kg, 50 g/kg and 80 g/kg dry matter (A 0 , A 2 , A 5 and A 8 , respectively) in addition to their basal diets. A 0 acted as a control group and measurements were recorded over a 56-d feeding period. Results: Sheep fed with AMT had a higher average daily gain (ADG) and a lower feed:gain ratio (F:G) than controls ( P < 0.001). Rumen concentrations of NH 3 -N ( P < 0.001), total volatile fatty acids (TVFA) ( P = 0.028), acetate ( P = 0.017) and propionate ( P = 0.031) in A 5 and A 8 were higher than in A 0 . The addition of AMT in the feed significantly increased serum antioxidant and immunity factors of the sheep and increased the concentrations of serum interleukin, immunoglobulin and tumour necrosis factor-α (TNF-α) ( P = 0.010). Conclusions: We concluded that AMT can be used as a feed additive to improve growth performance and rumen fermentation and enhance the immunity of Tibetan sheep. Some responses exhibited a dose-dependent response, whereas other did not exhibit a pattern, with an increase in AMT. The addition of 50 g/kg and 80 g/kg AMT of total DMI showed the most promising results.

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 < 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 < 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 > 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 > 0.05). There were no differences in albumin, T<sub>3,</sub> T<sub>4</sub> and growth hormone.

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.

The objective of the present study was to evaluate the effect of replacing corn with orange pulp (OP) on growth performance, rumen fermentation, nutrient digestibility and blood parameters of fattening lambs. Twenty male lambs were placed in individual pens and fed with four levels of replacement of corn by OP (0, 33, 66, 100%) during 60 days. Average daily gain (ADG) showed a quadratic effect (p<0.007) with the increasing levels of replacement. Inclusion of 33 and 66% of OP in the diet significantly increased dry matter intake (DMI) compared to control group (p<0.01). Ruminal ammonia-N concentration showed a linear decrease (p<0.002). Ruminal fluid pH increased linearly with the increasing replacement of corn by OP (p<0.001). Acetate concentration showed a linear increase (p<0.001). Plasma total protein showed a linear increase (p<0.002). Organic matter, crude protein and neutral detergent fiber showed a quadratic effect with the level of replacement. The results of the present study showed that replacement of corn by OP improves DMI of fattening lambs, leading to an enhancement in ADG at the replacement level of 40.3%. Also, total replacement of corn by OP did not have any adverse effect on growth performance, rumen fermentation, nutrient digestibility and blood parameters.

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.

This study aimed to investigate the effect of applying various silage additives to whole corn crops at ensiling on growth performance, rumen fermentation, and blood physiology in growing–finishing bulls. Sixty Simmental × Yellow Cattle crossbred bulls were blocked by initial body weight (BW; 324.0 ± 5.4 kg) into 15 blocks. Animals in each block were randomly assigned to one of four diets formulated based on the following corn silage: control (CON), inoculated with complex lactic acid bacteria (CLB), ensilaged with mixed organic acid salts (MS), and ensilaged with CLB and MS (CLBMS). The feeding experiment lasted over 155 days, with an additional 7 days for adaptation. The results showed that bulls fed CLB-inoculated silage had greater (p < 0.05) daily dry matter intake than the other groups. The experimental treatment had no significant effect on average daily gain (p = 0.33) and feed-to-gain ratio (p = 0.13), although bulls fed CLB-inoculated silage had a larger numeric average daily gain. All additive-treated silage increased ruminal NH3–N content (p < 0.05) and reduced the acetate-to-propionate ratio (p < 0.05) of bulls compared with the control group. Bulls fed CLB-inoculated silage had a lower ruminal pH value (p < 0.05) than that of the other groups. Compared with the control group, bulls fed CLB-inoculated silage had greater blood cholesterol, albumin, and urea nitrogen (p < 0.05). Blood physiological responses were similar in bulls fed MS-treated and control silage, whereas those in cattle fed CLBMS-treated silage were between bulls fed CLB- and MS-treated silages and more similar to the former. Taking animal performance and cost effectiveness into consideration, the application of CLB alone to whole corn crops at ensiling appears to be a better choice compared with the application of either MS alone or both of them together.

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.

Abstract Our objective was to determine whether the inclusion of pepper extract would improve health in suckling lambs, stimulating antioxidant activity, and improving performance. We used Lacaune lambs distributed in four treatments, with four repetitions per treatment and three lambs per repetition: control group (T0) and treatments T1, T2, and T3 that received 200, 400, and 800 mg/kg of pepper extract, respectively. Groups T1 and T2 consumed more significant amounts of silage than group T0, and animals from group T1 consumed more concentrate and, consequently, consumed more solids. The addition of pepper extract enhanced growth performance, with the lowest dose (T1) giving rise to the most significant weight gain, average daily gain, and body weight, compared to T0. Regression analysis showed that the optimum point for pepper extract supplementation was 301.5 mg/kg. The levels of total protein and globulins were significantly higher for animals supplemented with pepper extract (day 28) than the control; the concentrations of albumin and urea increased over time but did not differ significantly among treatments. Serum glucose levels decreased significantly over time; however, the groups supplemented with pepper extract showed higher concentrations than group T0. The hematocrit was significantly higher in groups fed pepper extract; hemoglobin concentrations were also more significant, increasing over time in both groups. The groups that consumed the pepper extract had higher leukocyte counts due to greater lymphocytes and neutrophils. Levels of non-protein thiols increased significantly over time, while lipid peroxidation levels decreased significantly in all groups. The concentrations of reactive oxygen species significantly decreased in the serum of group T3 animals, those fed with pepper extract (day 28), compared to the control. In general, the addition of pepper extract in lamb feed can enhance weight gain, increase antioxidant levels, and stimulate the production of leukocytes and globulins in lambs.
