Zinc Levels

The objective of this study was to investigate the effects of different sources and levels of zinc (Zn) on nutrient digestibility, plasma metabolites, and relative Zn bioavailability in male mink. Animals in the control group were fed a basal diet, consisting mainly of corn, soybean oil, meat and bone meal, and fish meal, with no Zn supplementation. Mink in the other 9 treatments were fed the basal diet supplemented with Zn from grade Zn sulfate (ZnSO<sub>4</sub><sup>. </sup>7H<sub>2</sub>O), Zn glycinate (ZnGly), or Zn pectin oligosaccharides (ZnPOS) chelate at concentrations of either 100, 300, or 900 mg Zn/kg dry matter. The results showed that zinc levels increased the AD of fat linearly (P &lt; 0.05). The AD of fat in Zn-900 was higher (P &lt; 0.05) than that of the control. Fecal Zn and urinary Zn were affected by dietary Zn addition (P &lt; 0.01). Moreover, Zn supplementation increased Zn retention compared with the control group (P &lt; 0.05). The N retention in ZnPOS was higher (P &lt; 0.05) than that of the control. The effect of Zn level was linear (P &lt; 0.01) for N retention. In addition, the activity of alkaline phosphatase was higher in groups supplemented with 900 mg/kg Zn (P &lt; 0.05) compared with the control group. There were significant interactions (P &lt; 0.05) among Zn sources on the activity of Cu-Zn superoxide dismutase (Cu-ZnSOD). Compared with ZnSO<sub>4</sub>, relative bioavailability values were 148% and 173% for ZnGly and ZnPOS, respectively, based on Cu-ZnSOD activity. In conclusion, our data show that the relative bioavailability of ZnPOS was greater than that of ZnSO<sub>4</sub><sup>. </sup>7H<sub>2</sub>O and ZnGly and Zn supplementation can enhance the Cu-ZnSOD of male mink, and mink can efficiently utilize ZnGly and ZnPOS.

, , , , and Antibiotics as growth promoters in poultry diets are currently restricted, so other feed additives, such as prebiotics and probiotics, have been suggested as an antibiotics alternative to improve the performance and gut health of poultry. The current experiment was conducted to study the effects of adding Mannan oligosaccharides (MOS) as a potential replacement for an antibiotic on productive performance, nutrient digestibility, some blood parameters, and caecal microbiota of broiler chickens. For conducting the current research experiment, a total of 180 one–day old Ross broiler chicks were randomly divided into one control group fed a basal diet and four dietary treatments with six replicates for each treatment. The treatment groups were fed a basal diet supplemented with different levels of MOS 0.5, 1, and 2 g/Kg diet and Lincomycin 4.4 mg/Kg diet during 35 days of the feeding trial. With exception of the growing period, the group fed a basal diet supplemented with 2 g MOS/Kg feed had considerably higher body weight and weight gain, while having the lowest feed consumption and best feed conversion ratio compared to the other treatment groups, during all experimental periods. Moreover, dietary supplementation of MOS resulted in a significant decrease in the counts of caecal E. coli and Enterococcus, while Lactobacillus and Yeast bacteria counts were significantly higher, compared to non-supplemented groups. Broiler chicks having a 2 g MOS/kg diet recorded lower values of cholesterol, low-density lipoprotein (LDL), urea, and liver enzymes, including Aspartate transaminase (AST) and Alanine aminotransferase (ALT), while they recorded significantly higher high-density lipoprotein (HDL), compared to the other experimental groups. Group treated with MOS 2 g/Kg feed improved digestibility of crude protein, ether extract, crude fiber, nitrogen-free extract, and organic matter, compared to the control group, Additionally, MOS supplementation also increased the intestinal villi length, width, and crypt depth and decreased intestinal inflammation, compared to the control group. In conclusion, supplementation of MOS at 2 g/kg diet improved growth performance, digestibility, and blood parameters without having adverse effects on the intestine of broiler chickens, comparable to the Lincomycin.

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.

The study was carried to evaluate the effects of feeding phytogenic feed additive, Artemisia absinthiumon nutrient intake, nutrient digestibility, utilization and performance of sheep. Ten male adult Bakerwal sheep were randomly divided into control group (T0) and treatment group (T1). The complete ration for T1 was fortified with herb Artemisia absinthium@ 4%. Significant (P less than 0.05) differences were observed in DM intake, OM intake, average daily gainand digestibility coefficients of DM, OM, CP and EE. However, non-significant (P less than 0.05) differences were recorded in digestibility coefficients of NFE, NDF, ADF and HC. Significant increase in % DCP and % TDN were recorded in T1 group as compared to T0 group. Nitrogen, calcium and phosphorus balance were comparable between two groups and were positive in both groups. Among haemato-biochemical parameters blood glucose, Hb, PCV and total serum proteins, differed non-significantly (P£0.05) between the groups, both before and after experimental feeding, except the BUN which was found significantly (P£0.05) higher in herb supplemented group.

The effects of restricting iron intake for the final 60 days of a 180-day growth trial on growth performance, nutrient digestibility, slaughter performance and meat quality of dairy bull calves used in veal production were evaluated in this study. Twenty-four newborn Holstein bull calves with an average weight of 41.0 ± 1.62 kg were randomly assigned to two groups of n = 12 calves/group. Calves in the Control group were fed a basal diet that included a milk replacer and pellet feed for 180 days. The iron level in the basal diet was 50 mg/kg. Calves in the Treatment group received the basal diet supplemented with 70 mg/kg iron for the first 120 days, then received the basal diet for the remaining 60 days. Five calves from each group were slaughtered at the end of the trial, and samples of the M. longissimus dorsi and rumen fluid were collected. No differences were found in dry matter intake, growth performance or digestibility and metabolism of nutrients between the two groups (P > 0.05). The dietary iron regimen did not affect the concentrations of blood urea nitrogen, total protein, albumin, or glucose (P > 0.05); however, the haemoglobin content increased with the supplementation of iron in the diet (P < 0.05). Compared with the Control group, increasing dietary iron increased the meat percentage (P < 0.05) rather than the meat nutritional composition or quality of veal.

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.

AbstractThe effects of feeding dried sweet potato (Ipomoea batatas) leaf (SPL) on growth performance, digestibility, and nitrogen (N) utilization were studied in sheep. Twenty-four rams with initial body weight of 18.5 ± 1.49 kg were randomly allocated to four treatments containing ad libitum natural grass hay alone (T1), hay + 150 g SPL (T2), hay + 300 g SPL (T3) and hay + 450 g SPL (T4) on as fed basis. Results indicated that dry matter (DM), organic matter (OM) and crude protein (CP) in-takes increased (P < 0.001) with increasing levels of SPL. Sheep fed with T2, T3 and T4 diets gained 55.1, 52.6 and 66.5 g per head per day, respectively, while the gain of non-supplemented sheep (9.19 g per head per day) differed (P < 0.05). Digestibility of DM, OM, and CP was higher (P < 0.01) for all supplemented sheep compared with the control. The CP digestibility and N retention were negative in non-supplemented sheep. Urinary N excretion decreased (P < 0.001) with the increasing levels of SPL supplementation. The N retention improved with the increasing levels of SPL and was the highest (P < 0.001) in sheep fed with T4 diet and the lowest in non-supplemented sheep. In conclusion, supplementing a basal diet of natural grass hay with SPL considerably improved the average daily gain, OM and CP digestibility and N retention.

Autochthonous Bacteria

Poor utilization efficiency of plant protein diets always leads to intestinal barrier dysfunction and growth inhibition in animals. Probiotics have shown promise in improving growth performance and gut health of the host. However, obtaining the host-beneficial probiotic from thousands of bacterial phylotypes is challenging. Here, four intestinal autochthonous bacteria were isolated from fast-growing bullfrog after a 60-day feeding on a soybean meal (SM)-based diet. Another feeding trial was conducted to evaluate the effects of supplementing these strains in an SM-based diet on growth, nutrient digestibility, immunity, and gut health of bullfrog. A high-SM basal diet was used as a non-supplemented control group (NC), and four other diets were prepared by supplementing the basal diet with 1 × 107 CFU/g of Bacillus siamensis, Bacillus tequilensis (BT), Bacillus velezensis, and Lactococcus lactis (LL). Results showed that weight gain, feed efficiency, nitrogen retention, and apparent digestibility coefficients of dry matter and protein were significantly higher in the LL group compared with the NC group (p &lt; 0.05). Furthermore, compared with the NC group, both BT and LL groups showed markedly higher jejunal protease and amylase activities, serum complement 4 and immunoglobulin M levels, jejunal muscularis thickness (p &lt; 0.05), and up-regulated expression of il-10 and zo-1 genes (p &lt; 0.05). High-throughput sequencing revealed higher abundances of Bacillus and Cetobacterium in BT and LL groups, respectively, accompanied with decreased abundances of Enterobacter and Escherichia–Shigella. Besides, KEGG pathways related to metabolisms were significantly enhanced by the LL diet relative to the NC diet (p &lt; 0.05). Overall, the beneficial effects of two frog-derived probiotics were determined: supplementation of L. lactis in SM-based diet promoted growth and nutrient digestibility; both B. tequilensis and L. lactis supplementation improved immune response and intestinal barrier function of bullfrogs.

This experiment was conducted to determine the bioavailability ofD-methionine (Met) relative toL-Met for nursery pigs using the slope-ratio assay. A total of 50 crossbred barrows with an initial BW of 13.5 kg (SD = 1.0) were used in an N balance study. A Met-deficient basal diet (BD) was formulated to contain an adequate amount of all amino acids (AA) for 10–20 kg pigs except for Met. The two reference diets were prepared by supplementing the BD with 0.4 or 0.8 gL-Met/kg at the expense of corn starch, and an equivalent concentration ofD-Met was added to the BD for the two test diets. The pigs were adapted to the experimental diets for 5 d and then total but separated collection of feces and urine was conducted for 4 d according to the marker-to-marker procedure. Nitrogen intakes were similar across the treatments. Fecal N output was not affected by Met supplementation regardless of source and consequently apparent N digestibility did not change. Conversely, there was a negative linear response (P< 0.01) to Met supplementation with both Met isomers in urinary N output, which resulted in increased retained N (g/4 d) and N retention (% of intake). No quadratic response was observed in any of the N balance criteria. The estimated bioavailability ofD-Met relative toL-Met from urinary N output (g/4 d) and N retention (% of intake) as dependent variables using supplemental Met intake (g/4 d) as an independent variable were 87.6% and 89.6%, respectively; however, approximately 95% of the fiducial limits for the relative bioavailability estimates included 100%. In conclusion, with an absence of statistical significance, the present study indicated that the mean relative bioequivalence ofD- toL-Met was 87.6% based on urinary N output or 89.6% based on N retention.

Abstract Background: Several studies indicated that dietary organic selenium (Se) usually absorbed better than an inorganic source, with high retention and bioavailability. Dietary Se as an antioxidant element affects the immune system and hematological status in animals. Therefore, the aim of this study was to evaluate the effect of dietary supplementation of bacterial selenium as an organic source on hematology, immunity response, selenium retention, and gut morphology in broiler chickens. Results: The present results revealed that supplementation of inorganic Se was associated with the lowest level of RBC, HB, and PCV with significant difference than ADS18-Se. In the starter stage, both T2 and T5 were associated with the significantly highest IgG level compared to the basal diet, while all supplemented groups showed higher IgM levels compared to the control group. In the finisher phase, all Se supplemented groups showed significant (P ˂ 0.05) increases in IgG, IgA, and IgM levels compared to T1. Birds fed bacterial-Se showed high intestinal villus height and better Se retention more than sodium selenite. The organic selenium of ADS18 had a superior action in improving Se retention compared to ADS1 and ADS2 bacterial Se. Conclusion: Bacterial organic Se had a beneficial effect on the villus height of small intestine led to high Se absorption and retention. Thus, it caused a better effect of Se on hematological parameters and immunity response.

This study aimed to evaluate the effects of the administration of sodium humate (NaH) on the growth performance, diarrhea incidence, and fecal microflora of pre-weaned Holstein calves. In a 53-day experiment, forty healthy newborn female calves were randomly allocated to the following four treatment groups: (1) control (basal diet); (2) 1-gram NaH (basal diet extra orally supplemented with 1 g of NaH dissolved in 100 mL of milk or milk replacer daily); (3) 3-gram NaH (basal diet extra orally supplemented with 3 g of NaH dissolved in 100 mL of milk or milk replacer daily); and (4) 5-gram NaH (basal diet extra orally supplemented with 5 g of NaH dissolved in 100 mL of milk or milk replacer daily). NaH was mixed with milk (d 2–20) or milk replacer (d 21–53). Calves in the 5-gram NaH group had a higher ADG during d 1 to 21 and d 21 to 53 than the other groups did (p < 0.05). Fecal scores and diarrheal incidence were significantly lower in the 3-gram and 5-gram NaH groups than the 1-gram NaH and control groups during d 1 to 20 (p < 0.05). The serum IgA, IgG and IL-4 concentrations, and T-SOD and T-AOC activities were higher, and the serum IL-6, TNF-α, D-lactic acid, and MDA concentrations were lower in the 5-gram NaH group than the control group (p < 0.05). Furthermore, NaH supplementation increased the abundances of Bifidobacterium and Lactobacillus but decreased the abundance of Escherichia coli in feces (p < 0.05). These encouraging findings indicated that supplementation with 5 g of NaH effectively improved the immune status, antioxidant capacity, and intestinal beneficial bacteria, and further improved the growth performance and reduced the diarrhea incidence of the pre-weaned dairy calves.
