This study was conducted to determine the effect of zinc on the productive performances, carcass yield and blood profiles of broilers. Experiment was done for a period of 35 days with a number of 60, day old broiler chicks. Birds were divided into four dietary treatment groups with 3 replications each having 5 birds per replication. The dietary treatment groups were; T0 (basal diet; no zinc), T1 (basal diet + 50 mg zinc/kg feed), T2 (basal diet + 100 mg zinc/kg feed), T3 (basal diet + 150 mg zinc/kg feed). Results revealed that body weight and body weight gain were significantly increased in the zinc supplemented group compared to the control group. Higher feed intake and better FE were also observed in the zinc supplemented group than the control group and the best performance was observed in the group fed 150mg zinc/kg feed (T3). Carcass yield was significantly higher in the groups fed dietary zinc. Net profit was slightly higher in the T3 group but not significantly (P.0.05) differed with the control group. However, T1 and T2 showed less profit even than the control group. Blood profile of the experimental birds including Hb, PCV, and ESR did not significantly differ among the groups. The results indicate that the addition of zinc in the broiler diet improves productive performances, carcass yield and increases net profit without affecting the health status of broiler. So, zinc can be used as an effective and useful micronutrient to improve the performances of broiler.

This study was conducted to evaluate the efficacy of dietary supplementation of Halquinol on productive performances, carcass characteristics and hematological parameters of Sonali chicken. A total number of 72 Sonali chicks of 07 days old were divided randomly into 04 experimental groups occupying 03 replications in each groups among which four dietary groups were considered i.e. control group (T0), Halquinol @ 0.25g/ kg feed in group (T1); Halquinol @ 0.5g/ kg feed in group (T2); and Halquinol @ 1g/ kg feed in group (T3) respectively. Results indicated that body weight and body weight gain were increased significantly (P<0.05) in birds supplied with Halquinol @ 1g/ kg feed group (T3) compared to the other groups. Higher (P<0.05) feed intake and better (P<0.05) FE were also observed in group T3 compared to the other groups. This result also indicated that body weight, body weight gain, feed intake, and feed efficiency were increased along with increasing dose of Halquinol. No significant (P>0.05) differences were found in dressing percentage, liver, heart and gizzard among the dietary treatment groups. However, the dressing weight, breast meat, thigh meat, and head weight was significantly (p<0.05) higher in birds supplied with Halquinol @ 1g/ kg feed group (T3) compare to control (T0) group. Present study revealed that hematological parameters, including Hb, PCV and ESR value of the birds of different groups does not differ significantly among the groups and it was within the normal range. Cost effective analysis of the experiment demonstrated that by using Halquinol @ 1g/ kg feed significantly (P<0.05) higher net profit than other dietary treatment groups and also highest profit over control (14.95Tk.). Based on the results of present study it may be suggested that supplementation of Halquinol can be used as a commercial growth promoter for the production of Sonali chicken. Asian J. Med. Biol. Res.

This experiment was conducted to investigate the influence of different dietary levels of zinc (Zn) on performance, vitamin B12, and blood parameters in lambs. Thirty six cannulated Poll Dorset × Small-tailed Han wether lambs were assigned randomly to four treatment groups: The control group, which was supplemented with 0.30 mg Co/kg dry matter (DM) to the basal diet; and the low-, medium- and high-Zn supplemented groups, supplementation of 50, 100, and 150 mg Zn/kg DM to the control diet, respectively. Lambs were housed in individual pens and the experiment lasted for 70 days. There was no significant difference in body weight gain and feed/gain between different treatment groups. The high-Zn supplemented lambs showed lower vitamin B12 concentrations in both ruminal fluid and plasma, and higher methylmalonic acid and homocysteine concentrations in plasma compared with the control and low-Zn supplemented groups (p < 0.05). No significant difference was observed in these biochemical values between the control, the low-, and the medium-Zn supplemented groups (p > 0.05). Plasma folate concentration, glucose, and heme-dependent blood parameters were not influenced by dietary zinc level. It was concluded that the higher level of zinc supplementation had a negative effect on vitamin B12 in lambs. Higher inclusion level of dietary zinc could inhibit vitamin B12 synthesis in the rumen of lambs.

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.

Abstract Background The aim of this study is to investigate whether the energy matrix values of the nonstarch polysaccharide- (NSP-) degrading enzymes, bioemulsifier (LYSOFORTE®), guanidinoacetic acid (CreAMINO®), or their combinations could be summed. The effects of these additives on the growth performance, carcass traits, and economic value of the broiler chicken diets were evaluated. A total of 525-one-day-old Ross chicks with an initial body weight of 42.96 ± 0.87 g were haphazardly allocated into seven groups with five replicates. The seven experimental treatments are as follows: (1) basal diet with no additives (breeder recommendation), which is the control group, (2) basal diet minus 100 kcal/kg supplemented with 0.02% NSP-degrading enzymes (NSP), (3) basal diet minus 50 kcal/kg supplemented with 0.025% emulsifier (LYSOFORTE®), (4) basal diet minus 50 kcal/kg supplemented with 0.06% guanidinoacetic acid (CreAMINO®), (5) basal diet minus 150 kcal/kg supplemented with a mixture of NSP and LYSOFORTE® (NSPL), (6) basal diet minus 100 kcal/kg supplemented with a mixture of NSP and CreAMINO® (NSPC), and (7) basal diet minus 200 kcal/kg supplemented with a mixture of NSP, LYSO, and CreAMINO® (NSPLC). The experiment lasted for 35 days. Results It was found that the final body weight, body weight gain, and relative growth rate were significantly higher in birds fed diets supplemented with NSPL, NSPC, CreAMINO, and LYSO with the reduced energy matrix value. The overall feed conversion ratio was significantly improved due to the supplementation of NSPC, CreAMINO, NSPL, and LYSO with the reduced energy matrix value compared to the control group. Moreover, no significant effect on the carcass criteria was observed by the different treatments. As a result of the dietary supplementation with NSPL, NSPC, CreAMINO®, and LYSO with the reduced energy matrix value, the net profit, total return, economic efficiency, and performance index were increased and the cost of feed per kg of body weight gain was decreased. Conclusion The energy matrix value of NSPL, NSPC, CreAMINO®, and LYSOFORTE could be established in the diets of broiler chickens to improve the growth performance and economic efficiency.

Broiler Production

This study was conducted to observe the effect of different administration method of garlic and neem on growth performances, feed efficiency and serum biochemical parameters for safe broiler production. The experiment was done for a period of 32 days with 384 one-day-old straight run broiler chicks. The broiler chicks were divided into six groups each of 64 birds and replicated to four subgroups each of 16 birds. The dietary groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), garlic in feed (basal diet + 0.25% garlic powder), garlic in water (basal diet + garlic extracts), neem in feed (basal diet + 0.25% neem powder) and neem in water (basal diet + neem extracts). Results showed that the body weight and body weight gain increased significantly (P<0.05) in both the garlic and neem groups compared to the control group. Feed intake was not different (P>0.05) among the treatment groups. Garlic in feed and water and neem in feed groups showed better FCR (P<0.05) compared to the other treatment groups. There were no significant (P>0.05) difference in meat yield, bone development and dressing parameters except head and gizzard in different dietary groups. Supplementation of garlic with feed and water significantly (P<0.05) decrease cholesterol, triglyceride and LDL compared to the other groups. However, both the garlic and neem groups showed numerically higher HDL compare to the control group. There were no 0significant (P>0.05) differences in serum glucose and GPT among different treatment groups. GOT was significantly (P<0.05) lower in neem groups than that of garlic and antibiotic groups. Additive groups showed higher profitability than control group. Based on the results of the study, it may be suggested that the garlic and neem could be used both in feed and water as potential feed additives for safe broiler production. Bang. J. Anim.

The objective of this study was to investigate the effect of Ca : total(t) P ratio, vitamin C and microbial phytase on broiler performance and cadmium retention of broiler. In experiment, 288 day-old male broiler chicks (Cobb) were randomly assigned to 12 treatment groups, 3 replicates of 8 chicks each. The study was carried out for 42 days. The basal diet supplemented calcium, phosphorus, cadmium (0.5 and 5 mg/kg), zinc (20 mg/kg), vitamin C (0 and 1 g/kg) and microbial phytase (0 and 600 PU/kg feed). Differences among diets fed to individual experimental groups affect either body weight gain or feed intake and conversion after the 3 weeks and at the end of the experiment (p &lt; 0.05). Cadmium and microbial phytase supplement to diet caused a significant increase of cadmium concentration in the tissues examined. There were significant differences in tissues concentrations of cadmium (p &lt; 0.05) among the groups fed diets supplemented. In conclusion, addition of 600 PU feed of phytase per kg of diet compensates this effect and lowers the cadmium burden by up to 60%.

This work aimed to explore the effects of dietary supplementation of Chlorella vulgaris (CLV) on the growth performance, carcass traits, hematobiochemical variables, immunity responses, and the antioxidant status of growing rabbits. A total number of 100 rabbits were randomly distributed into four treatment groups, each of five replicates (25 rabbits/group). The experimental groups were as follows; control: a basal diet without supplementation, CLV0.5: basal diet + 0.5 g chlorella powder/kg diet; CLV1.0: basal diet + 1.0 g chlorella powder/kg diet, CLV1.5: basal diet + 1.5 g chlorella powder/kg diet. Live body weight (LBW), cumulative body weight gain (CBWG), feed intake (FI), and feed conversion ratio (FCR) were not affected by dietary CLV supplementation. Platelet count (PLT), hematocrit (HCT), means corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) values were significantly increased in the CLV0.5 group compared with the other treatment groups. Dietary supplementation of CLV (1.5 g/kg diet) significantly reduced the alanine aminotransferase (ALT) activity. The concentrations of serum triglycerides and very low-density lipoprotein (VLDL) were lower (p < 0.05) in the CLV-treated groups than those of the control. Supplemental CLV at all experimental levels gave the best values of immunoglobulins (IgG and IgM) and glutathione activities. Malondialdehyde (MDA) levels were lower in the animals that received CLV in their diet than those of the control group. Dietary supplementation of 1.0 g CLV/kg had the potential to enhance immune responses and antioxidant status, as well as reduce blood lipid accumulation. Therefore, it could be concluded that CLV supplementation to growing rabbit diets can improve the health status.

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.

In Oman, efforts are underway to find alternative sources of fwd to support domestic livestock. The date industry thrives in Oman and one of its by-products is date fiber, a by-product of date syrup production. Although the product contains some free sugars, an evaluation of its potential in broiler diets has never been undertaken. Therefore, we conducted an experiment to investigate the value of date fiber in broiler chick diets. The experimental diets consisted of four graded levels of date fiber: 0, 15, 30 and 45 % in a broiler-starter ration replacing corn as an energy source. The diets were isonitrogenous. There were five replicates for each of the four diets and each replicate contained six broiler chicks. As date fiber percent increased in the dietary treatment, there were linear reductions in body weight gain, calculated apparent metabolizable energy (AMEn) content, and apparent protein digestibility (P < 0.05). Poor feed utilization (i .e., reduced feed efficiency) was observed in birds fed date fiber diets compared to the control group (P < 0.05). The poor performance of birds fed date fiber may be attributed to protein and energy limitations. We conclude that date fiber has no value in growing broiler diets. However, it may have utility in diets where a stable body weight is desirable.

Aim of study: Cull ewes are characterized by poor body condition, low body weights and tough meat texture. This work aimed to investigate the effect of distillated myrtle leaves (MDL) intake on body weight (BW) gain; carcass characteristics and meat quality of Barbarine cull ewes.Area of study: Northwest of TunisiaMaterial and methods: 27 Barbarine ewes were assigned into 3 groups receiving 500 g of oat hay and 750 g of concentrate control group (C), while they were given concentrate and pellets, containing 87% MDL, as substitute to hay in MHay group; for MConc group, they were fed hay, concentrate and pellets containing 30% MDL in partial substitution to concentrate. At the end of the fattening period (90 days), ewes were slaughtered.Main results: The dry matter intake was higher (p<0.05) for MConc and C groups. The average daily gain was significantly higher for C and MConc than MHay groups (113 and 107 vs. 87 g, respectively). Ewes fed MHay and MConc had a significantly lower feed conversion rate than Control group (12.5 vs. 15.4). Dietary treatment had no significant effect on carcass joint’s weight and proportions. The dressing percentage and carcass tissue composition were similar for all groups. The ultimate pH, water cooking loss and color parameters values were unaffected by the type of diet.Research highlights: These findings revealed that MDL could substitute, in ewes feeding, up to 87% to hay or up to 30% to concentrate without negative effects on body weight, carcass characteristics and meat quality.
