Intestinal Digestibility

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.

Abstract Oxidative stress seriously affects poultry production. Nutritional manipulations have been effectively used to alleviate the negative effects caused by oxidative stress. This study investigated the attenuating effects and potential mechanisms of dietary taurine on growth performance and meat quality of broiler chickens challenged with hydrogen peroxide (H2O2). Briefly, a total of 192 male Arbor Acres broilers (28-day-old) were randomly categorized into 3 groups: non-injection of birds on basal diets (control), 10.0% H2O2-injection of birds on basal diets (H2O2), and 10.0% H2O2-injection of birds on basal diets supplemented with 5 g/kg taurine (H2O2+taurine). Each group consisted of 8 cages of 8 birds each. Results indicated that H2O2 administration significantly reduced growth performance and impaired breast meat quality by decreasing ultimate pH and increasing shear force value (P < 0.05). Dietary taurine improved the body weight gain and feed intake, and decreased feed/gain ratio of H2O2-challenged broilers. Meanwhile, oxidative stress induced by intraperitoneal injection of H2O2 suppressed the nuclear factor-κB (NF-κB) signaling and initiated autophagy and apoptosis. Compared with the H2O2 group, taurine supplementation restored the redox status in breast muscle by decreasing levels of reactive oxygen species and contents of oxidative products and increasing antioxidant capacity (P < 0.05). Moreover, upregulated mRNA expression of NF-κB signaling-related genes including p50 and Bcl-2, as well as enhanced protein expression of NF-κB were observed in the H2O2+taurine group (P < 0.05). Additionally, dietary taurine decreased expression of caspase family, beclin-1 and LC3-II (P < 0.05), thereby rescuing autophagy and apoptosis in breast muscle induced by H2O2. Collectively, dietary supplementation with taurine effectively improves growth performance and breast meat quality of broilers challenged with H2O2, possibly by protecting against oxidative injury and modulating cell death signaling.

AbstractThe aim of this study was to determine the effect of different dietary levels and sources of methionine (Met) on the growth performance of turkeys, carcass and meat quality. A total of 816 Hybrid Converter turkeys in 6 groups and 8 replications were fed wheat-soybean meal-based diets supplemented with three sources of Met: DL-isomer, L-isomer and DL-hydroxy analog (DLM, LM and MHA, respectively). In four 4-week periods (from 1 to 16 weeks of age), the Met content of turkey diets corresponded to the level recommended by NRC (1994) or was increased by approximately 50% to match the intake recommended by some breeding companies. Increased dietary Met content resulted in a higher final body weight (BW) of turkeys (P=0.002) and a lower feed conversion ratio (FCR) (P=0.049), but had no effect on carcass dressing percentage and most parameters of carcass quality. The higher dietary Met level contributed to a decrease in meat pH, a lower contribution of redness and a smaller muscle fiber diameter (P=0.028, P=0.040 and P=0.004, respectively). The higher dietary Met level had no influence on the redox status of meat, but it reduced the incidence of lymphoid cell infiltration between muscle fibers threefold (P=0.003). Throughout the experiment, no significant differences were noted in the growth performance parameters of turkeys, irrespective of Met source. MHA contributed to higher abdominal fat content, lower dry matter (DM) content and lower catalase (CAT) activity in breast meat, compared with DLM and LM. Increased dietary Met content, approximately 50% higher than that recommended by NRC (1994), regardless of Met source, led to higher final BW of turkeys, but had no effect on carcass dressing percentage and most parameters of carcass quality.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.

Mannanoligosaccharides (MOS) can be used in poultry production to modulate immunity and improve growth performance. So, we hypothesized that our enzymatic MOS could achieve the same effects in broilers. To investigate this, a total of 192 one-day-old Partridge Shank chickens were allocated to four dietary treatments consisting of six replicates with eight chicks per replicate, and they were fed a basal diet supplemented with 0, 0.5, 1 and 1.5 g MOS per kg of diet(g/kg) for42 days. Treatments did not affect the growth performance of chickens. Dietary MOS linearly increased the relative weight of the bursa of Fabricius and jejunal immunoglobulin M (IgM) and immunoglobulin G (IgG) content, whereas it linearly decreased cecal Salmonella colonies at 21 days (p < 0.05). The concentration of jejunal secretory immunoglobulin A (sIgA) and IgG at 42 days as well as ileal sIgA, IgG, and IgM at 21 and 42 days were quadratically enhanced by MOS supplementation (p < 0.05). Also, chickens fed MOS exhibited linear and quadratic reduction in jejunal malondialdehyde (MDA) accumulation (p < 0.05). In conclusion, this enzymatic MOS can improve the immune function and intestinal oxidative status of Partridge Shank chickens.

Context Phytogenic applications in animal nutrition currently attract worldwide scientific attention for their potential to contribute positively to sustainable and high-quality animal production. However, further understanding and substantiation of dietary phytogenic functions is required. Aims The inclusion level of a phytogenic premix (PP) comprising functional flavouring substances from ginger, lemon balm, oregano and thyme was studied for its effects on broiler growth performance, carcass traits, nutrient digestibility, liver and meat total antioxidant capacity (TAC), and lipid oxidation. The expression of genes for nutrient transporter proteins (SGLT1, GLUT2, PEPT1, BOAT and LAT1), for FABP2 involved in cellular fatty acid uptake and metabolism, and for the mTORC1 complex relevant for protein synthesis were profiled along the intestine. Methods One-day-old Cobb broiler chickens (n = 500) were assigned to four treatments with five replicates of 25 chickens each. Starter (1–10 days), grower (11–22 days) and finisher (23–42 days) basal diets were supplemented with four levels of PP inclusion as treatments: 0, 750, 1000 and 2000 mg/kg diet, termed control, PP750, PP1000 and PP2000. Feed and water were available ad libitum. Data were analysed by ANOVA, taking the treatment as fixed effect. Statistically significant (P ≤ 0.05) effects were further analysed and means were compared using Tukey’s HSD test. Polynomial contrasts tested the linear and quadratic effect of PP inclusion levels. Key results Growth performance responses were not improved significantly (P &gt; 0.05) by PP inclusion level. However, carcass (P = 0.030) and breast meat yield (P = 0.023) were higher in PP1000 than in the control. In addition, PP1000 had higher (P = 0.049) apparent metabolisable energy than PP2000 and the control. Increasing PP inclusion level increased breast (P = 0.005), thigh (P = 0.002) and liver (P = 0.040) TAC. Breast and thigh meat TAC reached a plateau at PP1000, whereas liver TAC continued to increase linearly. Lipid oxidation in breast meat and liver was delayed linearly (P ≤ 0.05) with increasing PP inclusion level. Expression of genes SGLT1, GLUT2, PEPT1, BOAT and FABP2 were not affected by PP inclusion. However, PP inclusion affected the expression of LAT1 (P &lt; 0.001) in jejunum and of mTORC1 in duodenum (P = 0.010) and ceca (P = 0.025). In particular, expression increased with increasing PP inclusion level in a linear and quadratic pattern depending on the intestinal segment. Conclusions Overall, PP inclusion at 1000 mg/kg diet improved carcass and breast yield, dietary available energy, and overall meat and liver TAC. Preliminary evidence was highlighted for effects of PP in promoting expression of genes relevant for muscle protein synthesis. Implications This study has contributed new information on effects of a phytogenic premix on broiler meat yield and antioxidant capacity, digestibility, absorption and metabolic functions, further supporting phytogenic benefits for broiler production.

A feeding trial was conducted by supplementing Mentha arvensis (MA), Geranium thunbergii (GT) and liquid minerals (LM) in drinking water of pigs and the effects on growth, carcass characteristics and meat quality were evaluated. A total of 80 pigs were allocated into 4 treatments: control (0% plant extracts, 0% LM), T1 (0.1% LM + 0.1% 1 MA: 4 GT), T2 (0.1% LM + 0.1% 4 MA:1 GT), T3 (0.1 % LM + 0.1% 1 MA:1 GT). Weight gain was significantly increased in T3. However, the dietary treatments had no significant effect on carcass weight, back fat thickness and water holding capacity (WHC). A significant reduction in cooking loss and shear force was observed in T2. Considering the meat color, T3 significantly increased the a* value. Microbial count was significantly decreased (P less than 0.05) at 0-week of storage in T3. Our studies indicate that plant extracts and liquid minerals enhances the growth performance and meat quality, without any adverse effects.

Abstract Background: Weaning is associated with growth decline and morphological changes in the gastrointestinal tract of the pig. Insects, such as the Black soldier fly larvae (BSFL), are suggested as a sustainable novel protein source in diets for pigs. They contain chitin, medium chained fatty acids, and anti-microbial peptides, which could improve the gastrointestinal function and health in the post-weaning pig. The objective of this study was therefore to investigate the effect of increasing inclusion of full-fat BSFL in diets for post-weaning pigs on growth performance parameters, digestibility, gut morphology, and the microbial community in the colon. Eighty crossbred weanling pigs were weaned at approximately 32 days of age, with an average weaning weight of 10.6 ± 0.8 kg. For four weeks, the pigs were fed one of four dietary treatments: a control diet or one of three diets containing an increasing amount of full-fat BSFL meal: 4.76% (BSFL5), 9.52% (BSFL10), and 19.06% (BSFL20). Results: Increased level of full-fat BSFL in the diet did not affect growth performance or fecal consistency. A reduction in apparent total tract digestibility (ATTD) of crude protein (P = 0.035) was found for increased inclusion of BSFL, whereas the ATTD of crude fat increased (P<0.001). Jejunal, ileal, or colonic morphometry was not affected by the BSFL inclusion. Some changes in the colon microbiota were observed, but no differences in the short-chain fatty acid concentrations were detected between the dietary treatments. At the phylum level, dietary treatment affected the relative abundance of Bacteroidota, Firmicutes, Campilobacteria, and Thermoplasmatota, but there was no clear pattern relationship with the BSFL inclusion level. At the genus level, the inclusion of BSFL in the diet reduced the relative abundance of Lactobacillus (P = 0.015) compared to the control. Conclusions: Collectively, the results indicate that up to 19.06% of full-fat BSFL meal could be included in a balanced diet for PW pigs without affecting growth performance, gut function, or health.

Thirty six weaned mixed breed rabbits aged between 5 -6 weeks were used to investigate the growth performance and feeding cost of rabbits fed graded levels of oven dried poultry droppings. The rabbits were randomly assigned to four dietary treatments with three replicates and three rabbits per replicate in the ratio of 2:1 (2 females and I male) in a completely randomized design. poultry droppings were oven dried at 100 c, 80 c, 60 c, 40 c and incorporated at 0, 20, 40 and 60% levels of inclusion to replace ground nut in the compounded feed or experimental diets and designated as T1,T2 ,T3 and T4 respectively excluding treatment one (T1) . Data collected were subjected to Analysis of Variance (ANOVA. Growth performance performance of rabbits showed no significant (P>0.05) differences across the treatment groups. However highest average feed intake was recorded in T3 (40 %) inclusion level 473.60 g and the lowest in T3 (40 %) of 458.80 g. The result of cost of feeding revealed that as the inclusion level of oven dried poultry increased the cost of feeding rabbits reduces The trial revealed that oven dried poultry dropping can be used at 40 %level of inclusion in the rabbit dietwithout posing any threat to the animal.
