AbstractPurslane is a widespread wild vegetable with both medicinal and edible properties. It is highly appreciated for its high nutritional value and is also considered as a high-quality feed resource for livestock and poultry. In this study, Sanhuang broilers were used to investigate the effect of feeding purslane diets on the growth performance in broilers and their gut microbiota. A total of 48 birds with good growth and uniform weight were selected and randomly allocated to four treatment groups A (control), B, C and D. Dietary treatments were fed with basal diet without purslane and diets containing 1%, 2% and 3% purslane. The 16S rDNA was amplified by PCR and sequenced using the Illumina HiSeq platform to analyze the composition and diversity of gut microbiota in the four sets of samples. The results showed that dietary inclusion of 2% and 3% purslane could significantly improve the growth performance and reduce the feed conversion ratio. Microbial diversity analysis indicated that the composition of gut microbiota of Sanhuang broilers mainly included Gallibacterium, Bacteroides and Escherichia-Shigella, etc. As the content of purslane was increased, the abundance of Lactobacillus increased significantly, and Escherichia-Shigella decreased. LEfSe analysis revealed that Bacteroides_caecigallinarum, Lachnospiraceae, Lactobacillales and Firmicutes had significant differences compared with the control group. PICRUSt analysis revealed bacteria mainly enriched in carbohydrate metabolism pathway due to the additon of purslane in the diet. These results suggest that the addition of purslane to feed could increase the abundance of Lactobacillus in intestine, modulate the environment of gut microbiota and promote the metabolism of carbohydrates to improve its growth performance. This study indicates that the effect of purslane on the growth-promoting performance of broilers might depend on its modulation on gut microbiota, so as to provide a certain scientific basis for the application of purslane in the feed industry.

This study was conducted to investigate the effects of adding L-carnitine and Protexin(R) probiotic on performance and some blood parameters of ostrich chickens. In this study, a total of 48 one-day old ostrich chicks randomly divided into four treatment groups. Each treatment comprised of 4 replicates and 3 animals in each replicate and reared for 8 week. The experiment was arranged in a completely randomized design. The dietary treatments were: Treatment 1 (Control): Basal diet without supplementation; Treatment 2: Protexin(R) probiotic with level of 1 kg/t; Treatment 3: L-carnitine 500 mg/kg diet; Treatment 4: Protexin(R) probiotic with level of 500 kg/t + L-carnitine 250 mg/kg diet. The results of this study indicated that diet supplementation with L-carnitine and Protexin(R) probiotic increased ostrich chickens weight and feed intake at 8 weeks of age in comparison to other treatment groups. The other results showed no significant differences in feed conversion ratio (FCR) among different treatments at 8 week of ages and Broilers receiving L-carnitine + Protexin(R) probiotic had lowest FCR compared to the other tratment groups. Furthermore, diet supplementation with L-carnitine and Protexin(R) probiotic increased blood glucose concentration of ostrich chickens at 8 weeks of age in comparison to other treatment groups. Futher result showed that birds received L-carnitine + Protexin(R) probiotic had lowest total cholesterol in compersion to other treatment groups and birds receiving L-carnitine and Protexin(R) probiotic had lower HDL, LDL, and VLDL concentrations in compersion control group. There were no significant effect in calcium and phosphorus concentrations between control and other treatment groups.

The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

Marine algae polysaccharides have been shown to regulate various biological activities, such as immune modulation, antioxidant, antidiabetic, and hypolipidemic. However, litter is known about the interaction of these polysaccharides with the gut microbiota. This study aimed to evaluate the effects of marine algae Enteromorpha (Ulva) prolifera polysaccharide (EP) supplementation on growth performance, immune response, and caecal microbiota of broiler chickens. A total of 200 1-day-old Ross-308 broiler chickens were randomly divided into two treatment groups with ten replications of ten chickens in each replication. The dietary treatments consisted of the control group (fed basal diet), and EP group (received diet supplemented with 400 mg EP/kg diet). Results showed that chickens fed EP exhibited significantly higher (P < 0.05) body weight and average daily gain than the chicken-fed basal diet. In addition, significantly longer villus height, shorter crypt depth, and higher villus height to crypt depth ratio were observed in the jejunal and ileal tissues of chickens fed EP. EP supplementation upregulated the mRNA expression of NF-κB, TLR4, MyD88, IL-2, IFN-α, and IL-1β in the ileal and jejunal tissues (P < 0.05). Besides, we observed significantly higher (P < 0.05) short-chain volatile fatty acids (SCFAs) levels in the caecal contents of the EP group than in the control group. Furthermore, 16S-rRNA analysis revealed that EP supplementation altered gut microbiota and caused an abundance shift at the phylum and genus level in broiler chicken. Interestingly, we observed an association between microbiota and SCFAs production. Overall, this study demonstrated that supplementation of diet with EP promotes growth performance, improves intestinal immune response and integrity, and modulates the caecal microbiota of broiler chickens. This study highlighted the application of marine algae polysaccharides as an antibiotic alternative for chickens. Furthermore, it provides insight to develop marine algae polysaccharide-based functional food and therapeutic agent.

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.

Hepatic Histopathology

Mycotoxins are toxic secondary metabolites produced by different strains of fungi, such as aspergillus, fusarium, and penicillium that can contaminate feed ingredients or the entire feed of poultry and animals. Mycotoxins can cause many serious complications to both humans and animals due to carcinogenic, mutagenic, and immunosuppressive disorders. Therefore, the present experiment aims to investigate the effect of broiler chickens’ diets supplemented with different levels of nanosilica (NS) as an adsorbent agent of mycotoxins on their growth performance and hepatic histopathology. Detectable levels of toxins were present in the feed before feeding, and all levels of mycotoxins were above the normal limit. A total of 180 one-day-old male Arbor Acres broiler chickens were allocated randomly to six treatment groups with three replicates per group, including ten chickens per replicate. The experiment lasted for five weeks, and dietary treatments included control diet and diets with four levels of nanosilica as 0.05%, 0.10%, 0.15%, and 0.20% as well as 0.50% bentonite (fixfin® Dry) diet. Bodyweight, body weight gain, average daily feed intake, and feed conversion ratio were measured weekly. At the end of the fifth week, six chickens per treatment were sacrificed to investigate the effects of NS and bentonite on carcass characteristics and hepatic histopathology. The results showed that providing broiler chickens’ diets with an adsorbent agent, such as NS or bentonite, can reduce the side effects of mycotoxins and enhance their growth performance. The best record was achieved with NS at 0.20%, compared with the control group and other dietary treatment groups. Accordingly, 0.20% of NS could be used in broiler chickens’ diets to minimize the harmful effects of mycotoxins.

<p>The present study evaluated the effect of dietary <em>Eucommia ulmoides leaves</em> (EUL) on growth performance and antioxidant status of growing rabbits under heat stress condition. Four hundred and fifty weaned New Zealand male rabbits (6 wk old) were randomly divided into 3 equal groups (150 rabbits/group) and fed with a basal diet (control, digestible energy (DE): 15.92 MJ/kg and crude protein (CP): 19.24%) or the basal diet supplemented with 1 or 5 g of EUL/kg of diet (EUL1 and EUL5), in which the same quantity of barley meal was replaced. During the 21 d of experiment (43 to 63 d of age), the temperature and relative humidity of the rabbit house ranged from 27.5 to 32.5°C and from 65 to 73%, respectively. We analysed feed intake, growth performance and antioxidant status of growing rabbits. Compared with the control group, at the end of the experimental period, EUL supplementation significantly reduced the average daily feed intake (92.0, 92.8 and 100.7 g/d for EUL1, EUL5 and control, respectively; P&lt;0.05), improved the feed conversion ratio (3.80, 3.81 and 4.59 for EUL1, EUL5 and control, respectively; P&lt;0.05), increased the activities of glutathione peroxidase (+35.5 and +35.0% in plasma and liver of rabbits in EUL5 vs. control group, respectively; P&lt;0.05) and reduced those of malondialdehyde (–12.0 and –46.0% in plasma and liver of rabbits in EUL5 vs. control group, respectively; P&lt;0.05). These results suggest that inclusion of EUL in the diet of growing rabbits improved the growth performance and antioxidant status in growing rabbits.</p>

The effects of supplementing different urea molasses blocks to Yankasa Rams fed maize offal-based diet on nutrient intake, growth performance and economics of production were evaluated. Yankasa rams fed cowpea shell and maize offal-based diets mixed in a ratio of 1:3 supplemented with urea molasses block (UMB). The supplementary blocks were formulated to contain 0, 5, 10 and 15% urea. Twenty Yankasa rams were used for the experiment with initial body weights range of 16-20kg and randomly allocated to four treatment groups of five animals each in completely randomized designed. Data on feed and water intake, body weight change were measured. Rams were fed both the basal diet and supplements ad libitum. The result revealed no significant (P>0.05) difference in basal feed (579.38-595.18g/day), UMB (60.78-96.50g/day) and dry matter intakes (584.36-609.33 g/day) among the treatments. Rams on treatment 3 recorded the highest average daily weight gain (ADG) and feed conversion ratio (FCR) (101.43 g/day, 5.93) than those on treatment 2 (48.57 g/day, 12.37) with the least. The cost of UMB/kg was least in treatment 3 (N 46.66) compared to those on treatment 1(N 83.66), 2(N 113.05) and 4(N 50.39). Supplementation of urea molasses block improved growth performance and FCR. Urea up to 15% may be included in urea molasses blocks without any detrimental effects on performance. However, including urea at 10% in UMB gave the highest ADG and FCR and therefore may be recommended for growing Yankasa rams

Mannan Oligosaccharides

The study aimed to evaluate the effect of inulin and mannan-oligosaccharides (MOS) vs zinc-bacitracin (ZnB) on rabbit growth performance, nutrient digestibility, and blood profiles. In total, 108 rabbits 32 days of age were divided into four homogeneous groups fed the same basal diet and submitted to the following dietary treatments: control group, without supplementation; inulin group, supplemented with inulin (0.25 g/rabbit.day); MOS group, supplemented with MOS (0.083 g/rabbit.day); and ZnB group, supplemented with ZnB (0.083 g/rabbit.day). The supplements were administered 2 days per week from 32 to 81 days of age. At 32, 56 and 81 days, the rabbits were weighed and feed intake was measured. Mortality was recorded daily. Nutrient digestibility was measured at 65 days by an ingesta–excreta balance. Samples of blood were collected at 53, 67 and 81 days of age. The control group showed the highest (P < 0.01) mortality rate throughout the trial (17.0%), followed by ZnB (8.18%), inulin (3.7%) and then the MOS group, which had the lowest mortality (1.6%; P < 0.01). Addition of MOS led to a more favourable (P < 0.05) feed conversion ratio than addition of ZnB at 32–56 days of age and inulin for the entire trial period. The MOS group showed increased (P < 0.01) digestibility of dry matter, organic matter, ash and crude fibre relative to the control group. All supplements increased (P < 0.01) protein digestibility relative to the control. The level of alanine aminotransferase was reduced due to the use of feed supplements, and MOS supplementation gave the lowest (P < 0.01) value. Administration of prebiotics to growing rabbits as an alternative to ZnB can lead some advantages compared with both antibiotic and unsupplemented diets; MOS was more effective than inulin.

This research was conducted to evaluate the effect of probiotic supplementation on growth performance, gut microbiota, and hematology of local quails. Ninety-one-week-old quails were randomly distributed into three dietary treatments with three replicate per each for 42 days. The dietary treatments were: Treatment 1 which was control (no additive), standard diet added with Lactobacillus animalis bacteria 1 g/kg 1.35 × 109 colony forming units (CFU)/kg (PRO1) and commercial multi-strain probiotic (Lactobacillus acidophilus 2.75 × 1010 CFU, Streptococcus faecium 8.25 × 1010 CFU, and Bacillus subtilis 1.1 × 1010 CFU) (PRO2). Results showed that PRO1, isolated from chicken caeca, had probiotic properties to improve growth performance of local quail compared to the control group. In cecum digesta, addition of both types of probiotics significantly increased the number of Lactobacillus spp. and reduced the number of coliform bacteria at the end of the experiment. Furthermore, supplementation of both types of probiotics significantly increased the number of lymphocyte and reduced H/L ratio compared to the control group at the end of the experiment. While, no significant differences were observed between both types of probiotic. This research has established that L. animalis, which isolated in cecum of chicken origin, had the same data recorded when compared to commercial multi-strain bacteria probiotic by improved growth performance, gut microbiota, and hematology parameters and could be a convenient probiotic additive in dietary local quail.
