This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Abstract Background Probiotics are used as a means to improve animal health and intestinal development. Saccharomyces boulardii is a well-known probiotic; however, few studies have examined the effects of S. boulardii on weaned piglet performance. Therefore, this 28-day study compared the effects of S. boulardii mafic-1701 and aureomycin in diets for weaned piglets on growth performance, antioxidant parameters, inflammation and intestinal microbiota. One hundred and eight piglets, weaned at 28 d of age (8.5 ± 1.1 kg), were randomly divided into the three dietary treatment groups with six pens and six piglets per pen (half male and half female). The dietary treatment groups were as follows: 1) basal diet (CON); 2) basal diet supplemented with 75 mg/kg aureomycin (ANT); 3) basal diet supplemented with 1 × 108 CFU/kg S. boulardii mafic-1701 (SB). Results Compared to CON group, SB group had higher feed efficiency (P < 0.05) in the last 14 d and lower diarrhea rate (P <  0.05) over the entire 28 d. Total superoxide dismutase in serum was markedly increased in SB group (P < 0.05). Moreover, compared with CON group, SB group decreased the levels of pro-inflammatory cytokines interleukin-6 (P <  0.01) and Tumor necrosis factor-α (P < 0.05) in jejunum. Supplementation of S. boulardii mafic-1701 increased the abundance of Ruminococcaceae_UCG_009 and Turicibacter (P < 0.05), whereas the abundance of unclassified_Clostridiaceae_4 was decreased (P < 0.05). Furthermore, S. boulardii mafic-1701 administration increased cecal concentration of microbial metabolites, isobutyrate and valerate (P < 0.05). Conclusions The improvement in feed conversion ratio, reduction in diarrhea rate in weaned piglets provided diets supplemented with S. boulardii mafic-1701 may be associated with enhanced antioxidant activity, anti-inflammatory responses and improved intestinal microbial ecology.

Broiler chicken performance feed ration containing pineapple peel meal and supplemented by yoghurtABSTRACT. An experiment was conducted to determine the broiler performance feed ration contained pineapple peel meal supplemented by yoghurt. A hundred broiler chickens 2 days old were used in this study those divided into 4 treatment groups and kept for 4 weeks. The treatments were level of pineapple peel meal (PPM) into the ration; P0 = ration without PPM, P1 = ration contained 5 % of PPM, P2 = ration contained 10 % of PPM and P3 = ration contained 15 % of PPM. To neutralize high crude fiber content in the ration, chickens were supplemented by yoghurt consisted 3,3 x 108 CFU/ml of Lactobacillus bulgaricus and Streptococcus thermophilus as much as 3 ml/kg body weight. Yoghurt was offered in the morning before feeding. Each treatment was replicated 5 times. The experiment was assigned into Completely Randomized Design with 4 treatments and 5 replications. Parameters were feed consumption, water consumption, body weight gain and feed conversion ratio. Data were analyzed by Analysis of variance (ANOVA) and significantly effect was tested by Duncan’s Multiple Range Test. Results of this study showed that there was no significant difference (P0.05) among 0, 5, and 10 % the treatment groups on feed consumption, water consumption, body weight gain and feed conversion ratio. Offered 15 % of pineapple peel to the chickens did not significantly (P0.05) increased feed consumption and conversion ratio but did not significantly (P0.05) decreased body weight gain.  It is concluded that pineapple peel meal might be mixed into the broiler chicken ration up to 10 % without any significant adverse effect  on performance when they were supplemented by yoghurt as much as 3 ml/kg of body weight.

Considering the inherent attributes of tannia cocoyam (Xanthosoma sagitifolium) its appropriate utilization may enhance performance of starter broiler chicks. This study was therefore carried out to determine the dietary evaluation of starter broiler chicks fed cooked cocoyam tuber meal as energy source in place of maize. The cooked cocoyam tuber meal was used to replace maize at various levels of 25%, 50%, 75% and 100% respectively for diets 2, 3, 4 and 5 to determine the best replacement level that would give optimal performance in starter broiler chicks' diets. Result of the proximate composition of cooked cocoyam tuber meal showed that it contained 13.11% moisture, 2.60% ash, 1.85% ether extract, 3.90% crude protein, 9.45% crude fibre, 70.13% nitrogen free extract and 3004.37 Kcal/kgME. 150 day old Anak broiler chicks were used for the experiment. They were divided into 5 treatment groups of 30 broiler chicks each. Each treatment group was subdivided into 3 replicates of 10 broiler chicks each and kept in deep litter. Each starter diet was fed to a group of 30 starter broilers for 4 weeks using completely randomized design. They were given feed and water adlibitum. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and economics of production. In the starter broiler feeding trial, the starter broilers on 25% cooked cocoyam meal compared favourably with the control (P> 0.05) in terms of feed intake, body weight gain and feed conversion ratio and significantly (P > 0.05) performed between than those on 100% CCYM. The cost of production (N/Kg broiler) was however cheapest for diet 2 (25% CCYM) N395 versus control diet (N494.28). It was therefore concluded that cooked cocoyam tuber meal (Xanthosoma sagitifolium) could be used in the diets of starter broiler chicks' up to 25% without affecting the body weight gain, feed intake and feed conversion ratio as indicated in this study.

An experiment was conducted with 312 day-old male broiler chicks in grower phase(8-28d) to estimate the biological availability of four sources Zinc (Zn), Zinc sulfate(ZnSO4.H2O), two sources of Zinc oxide(ZnO FG1 and ZnO FG2) and Bioplex Zn. Zinc sulfate (ZnSO4.H2O) was used as the standard in the bioavailability assay. Chicks were allotted randomly to 13 dietary treatments with 6 birds per replicate and 4 replicates per treatment, that included an unsupplemented corn-soybean meal basal diet (25.50 mg of Zn/kg of DM), or the basal diet supplemented with 100, 150 or 200 mg/kg of DM as either ZnSO4.H2O (33 % Zn), Zinc oxide FG1(72%Zn), Zinc oxide FG2 (75%Zn) or Bioplex Zn (15% Zn). Dietary Zn level and source had no effect (P>0.05) of feed intake or body weight gain of chicks during first and second weeks of experimental periods, but feed conversion ratio in the first and second week and feed intake, body weight gain or feed conversion ratio in third week and total experimental periods were significant difference between treatments (P<0.05). The relative biological availability values using body weight gain were estimated to be 59, 99 or 45 for three levels of Zinc oxide FG1, 64, 78 or 31 for three levels of Zinc oxide FG2 and 151, 200 or 147 for three levels of Bioplex Zn, respectively. From the standpoint of bioavailability, Bioplex Zn was more available to broiler chicks than Zn from other sources and can be used by the feed industry as sources of supplemental Zn for broiler chickens.

Some available forages during the dry season can serve as a backup for ruminants andpseudo ruminants such as rabbits. One of such forages is the plantain leaf (PL). Due toscarce information of its effect on rabbits, this study was therefore, conducted to determine the organs response upon feeding it. Thirty mixed bred rabbits were randomly allotted to five experimental treatments. Five treatments were: concentrate compounded diet (T1/control), while T2, T3, T4 and T5 comprised T1(30g PL) and 25g, 50g, 75g and 100g plantain leaf (PL), respectively. The study lasted for 56 days. The parameters measured were liveweight, liver, kidney (left and right), bile, lungs, heart, testes and ovary. The performance data showed that mean body weight gain and feed conversion ratio were significantly (p<0.05) better in rabbits fed the concentrate (12.14 g/d and 4.65 respectively) than other treatments, though those on T5 was comparable. For the live weight, there were no significant differences amongst the treatment. There were no significant (p>0.05) differences in the organ weights of the rabbits for all the parameters measured except bile, and heart which were significant (p<0.05). Rabbits on T1 recorded the highest weight (3.93% dressed weight) in heart though similar (P>0.05) with those on T3 (2.60%). However, rabbits on T5 recorded a higher numerical weight (p>0.05) for liver, kidney (left and right) and ear (left and right). From the results, it can be concluded that feeding up to 100g/day of plantain leaf did not pose any adverse effects on the organ weights of weaner rabbits.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

Background: Rapid population growth of human and livestock create increasing demands for food, nutrition security in developing countries and therefore alternative feed resources must be identified and evaluated. This study was carried out to investigate the effects of Moringa oleifera leaf meal (MOLM) on supplemented feed on the growth and carcass quality of broilers in Calabar. Methodology: Fresh leaves of Moringa oleifera were bought and collected from Calabar, Nigeria. The leaves were dried for four days and milled. A total of 40 broiler chicks that 48 day-olds, unsexed (rose 308) were sourced from a reputable poultry farm in Calabar. The broiler chicks were randomly allotted to four treatment groups (A, B, C and D). 0%, 5%, 10% and 15% of MOLM were incorporated into the broiler feed which constituted the four treatment groups. Each group was replicated ten times at 10 birds per replicate. The following parameters were taken including feed intake, weight gain, feed conversion ratio, mortality rate and carcass quality. Data were subjected to statistical analysis. Results: The diet supplemented with 5% of MOLM showed significantly high body weight and followed by 10% of MOLM. Feed intake values were significantly (p<0.05) different across the treatment groups. The weight gain (WG) was statistically similar for group B and C but significantly (p<0.05) different in group D; with birds fed with 10% MOLM based diet having the highest WG. The feed conversion ratio of the birds were not significantly (p>0.05) different in group B and C, but differed significantly (P<0.05) in group D when compared with the control in group A. Carcass characteristics showed higher values of dressing percentage in birds fed supplemented with 10% MOLM (group C). The levels of MOLM were not significantly different in terms of liver weight, heart weight, kidney weight and abdominal fat. Conclusion: Overall, the best significant improvement in the response indices were obtained in birds fed 10% MOLM, while there was a reduced performance of birds feed with 15% MOLM.

A total of 144 day-old Anak 2000 strain of broiler chicks were used in the study. A basal diet was formulated and supplemented at 0, 200, 400, 600 mg kg of MgSO4 to constitute four dietary treatments. The birds were randomly allotted to the four dietary treatment groups and replicated thrice (12 birds per replicate). The performance characteristics, rutrient digestion coefficients, Mg utilization coefficients and haematological and biochemical parameters of the birds were determined Feed conversion ratio, crude protein retention, Mg utilization and blood parameters were highest in birds fed diet containing 400mg kg MgSO4 There were significant (p<0.05) differences in the final body weight, weight gain, Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER) and crude protein retention Liver Mg content, Mg intake and excretion increased significantly in a dosage dependent manner. Nutrients digestibility increased significantly as Mg levels increased from 0 to 400mg though, digestibility coefficients of Mg were significantly (p>0.05) depressed across treatments. However, serum Mg, Mg digestibility coefficient and tissue Mg residue were similar across treatment groups. The results showed that inclusion of 400mg kg supplemental MgSO4 in practical broiler starter diets resulted in improved performance and nutrients digestibility of the birds.
