Background: Copper (Cu) is an essential trace mineral for growth, production and health of poultry. Due to its poor absorption from inorganic source which is common supplemental form, large amount of Cu is excreted in the excreta. This experiment was conducted to assess the bioavailability of Cu from organic and nano sources at lower level of supplementation to reduce the excretion level without compromising the growth performance of chicken. Methods: A total of 420-day-old Giriraja chicks were randomly assigned to 7 treatment groups having 4 replicates each (15 chicks per replicate). The basal diets of both chick (0-6 weeks) and grower phases (7-10 weeks) were supplemented with 20 and 30 ppm of Cu from inorganic source as control (T1), the groups T2, T3 and T4 supplemented with 100, 75 and 50% of control from organic Cu, T5, T6 and T7 treatment diets supplemented with 75, 50 and 25% of control from Cu nanoparticles, respectively. Result: The grower phase and cumulative body weight gain was significantly (p less than 0.05) higher in T2 compared to T1, T6 and T7 groups, while the feed intake in chick phase was lower in T2, T5 and T7 groups as compared to T1, T3, T4 and T6. The chick phase feed conversion ratio was significantly (p less than 0.05) better in T2 and T5 groups compared to T1, T3, T4, T6 and T7, whereas the cumulative FCR was better in T2 and T5 compared to T6 and T7 groups, while it was not affected during grower phase. The dry matter and crude protein metabolizability were significantly (p less than 0.05) higher in T2 and T5, the organic matter and ether extract metabolizability was higher only in T5. The crude fiber and nitrogen free extract was not affected by the treatment diets. Nitrogen excretion was significantly (p less than 0.05) lower and its retention was higher in T2 and T5 treatment groups but was comparable with control. The Cu excretion through excreta was significantly (p less than 0.05) higher and its retention was lower in control as compared to all dietary treatments. Hence, it was concluded that the Cu supplementation from organic or nanoparticles form can be reduced by 50 and 75% of standard, respectively without compromising the growth performance of birds and nutrient digestibility of diets.

The increase in human population, particularly in the developing countries like Nigeria and the demand for animal protein intake has necessitated different approaches of solving protein shortage. A 28-day study was carried out to determine the performance of finishers fed on different hourly soaked doum palm (Hyphaene thebaica) pulp meal (DPPM) diets. Two hundred and sixteen (216) finishers (4 week-old) were randomly allotted to six dietary treatments. Each treatment consisted of 36 birds with three replicates (12 birds per replicate) in a completely randomized design (CRD). Six experimental diets were formulated and designed as follows: T1 (Control) contained 0% DPPM while T2, T3, T4, T5 and T6 contained 12.5% each of 2, 4, 6, 8 and 10 hours soaked DPPM as substitute for maize, respectively. Feeds and water were provided ad libitum for all treatment groups. The average body weight gain (40.44- 42.71 g/b/d), average feed intake (87.52-96.73 g/b/d) and feed conversion ratio (2.14-2.34) were non-significant (p>0.05) regardless of the dietary treatments. Statistical differences (p<0.05) were observed in some carcass parameters such as thigh (13.40-14.98%), neck (5.32-6.55%), shank (3.81-5.2 %), wing (9.80-11.41%), head (2.43-3.74%) and two haematological indices; white blood cell (160.67-189.53 X 103/mm3) and eosinophils (0.33-2.00%) across the treatment groups. The processed DPPM could serve as a rich energy source in broiler feeds with the raw doum palm pulp containing 2987.45 kcal/kg. Also, soaking the pulp for 2 to 10 hours before been included in broiler diet improved the nutritional content, acceptability, palatability and utilization of the feed by the broilers. Thus, up to 12.5% processed DPPM can be included in the diets of broiler chickens without adverse effect on growth performance, nutrient digestibility, carcass characteristics and haematological indices of chickens.

A study was carried out to determine the effect of Crina Poultry Plus®, a natural blend of essential oils and benzoic acid. on the growth performance, carcass yield and nutrient digestibility of broiler chickens. Six treatment diets were formulated by the addition of Crina Poultry Plus (CPP®) at 0, 0.2, 0.3, 0.4, 0.5 and 0.6g/kg of feed. Two hundred and forty day-old chicks were allocated to the six dietary treatments with each treatment having four replicates. Each replicate had 10 broilers. The parameters measured were live weight, live weight gain, feed intake, feed conversion, protein efficiency ratio, carcass and organ    characteristics, nutrient utilization and feed cost benefit. Results of growth performance showed that there were no significant differences (P>0.05) across the treatment groups, but birds fed diets supplemented with CPP® had significantly heavier body weight (BW), higher average daily weigh gain live weight gain and similar feed conversion ratio when compared with the control group. The dressing percentage, thigh, drum stick, breast cut and back cut were not significantly (P>0.05) different across the treatment groups but those fed diet supplemented with CPP® had higher values when compared with the control diet. The supplementation of CPP® improved nutrient digestibility in broiler chickens. Birds fed diet containing 0.6g of CPP® had numerically lower cost per kg of weight gained compared to other treatment groups. It can be concluded that the addition of 0.6 g CPP® in broiler diets improved performance, carcass, organ characteristics and nutrient utilization of broilers.

We investigated the effects of a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) supplementation in 800 1-d-old male Ross 308 broiler chickens (42 ± 0.90 g) in a 7-week study. Broiler chicks were randomly allocated into one of the five dietary treatments (16 birds per pen with 10 pens per treatment). Dietary treatments consisted of corn-soybean meal based basal diet and the basal diet supplemented with blend of OAs and MCFAs at 0.25, 0.5, 0.75 g, and 1 g per kg of feed. In the current study, during the whole experimental period, the inclusion of the blend of OAs and MCFAs in the basal diet linearly improved (p < 0.05) body weight gain (BWG), feed conversion ratio (FCR), and dry matter digestibility. The increasing inclusion of the blend of OA and MCFA levels in the diets linearly decreased (p = 0.002) feed intake during d 1 to 7. Broilers fed diets containing different levels of the blend of OAs and MCFAs showed a linear increase (p = 0.006) in Lactobacillus concentrations and decrease (p = 0.014) in ammonia (NH3) at the end of the experiment. However, the blend of OAs and MCFAs did not affect carcass quality, E. coli, and Salmonella counts, as well as hydrogen sulfide and total mercaptans gas emission (p > 0.05). In conclusion, the blend of OA and MCFA supplementation positively influenced growth performance, DM digestibility, excreta Lactobacillus counts, as well as NH3 gas emission in broiler chickens.

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.

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

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 aim of the study was to investigate the effect of Bacillus licheniformis and salinomycin supplementation in broiler diets as individual factors or in combination on the growth performance, GIT morphometry, and microbiota populations. Four hundred one-day-old Ross 308 chicks were randomly distributed to four dietary treatments (10 replicates, 10 birds each). The following treatments were applied: NC—no additives; NC + SAL—salinomycin addition (60 mg/kg diet), NC + PRO—B. licheniformis DSM 28710 preparation (1.6 × 109 CFU/kg; 500 mg/kg diet), and NC + SAL + PRO—combination of salinomycin and B. licheniformis. Probiotic administration resulted in improvement (p < 0.05) of the performance parameters, including body weight gain (1–10 d, and 11–22 d) and feed conversion ratio (11–22 d, 1–36 d). An interaction (p < 0.05) between experimental factors was observed in terms of lower pH values in the crop (tendency, p = 0.053) and ceca. Both factors lowered the alpha diversity and Enterobacteriaceae and promoted Bacillaceae communities in the jejunum (p < 0.05). Interactions were also observed in terms of reducing Clostridiaceae in the ceca. In conclusion, the combined use of B. licheniformis and salinomycin in broilers’ diets had beneficial effects.

Background: Fat and oil are commonly used in poultry diets to increase energy density and also to increase the palatability of feed, feed efficiency and for deposition of fat in broilers. Thus a study was proposed to find the effects of dietary replacement of saturated fatty acid rich palm oil (PO) by omega-3 rich rapeseed oil (RO) on growth performance and economics in broilers. Method: The growth performance feeding trial was conducted in 160 day-old broilers (vencobb 400) with four treatment groups (G1, G2, G3 and G4) with four replicates of ten chicks each. The basal diet (R1) was prepared with palm oil included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively and fed to G1. The other treatment groups G2, G3 and G4 received R2, R3 and R4 experimental rations respectively. The experimental rations R2, R3 and R4 were prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil which was included in R1. Result: The broiler ration prepared with rapeseed oil at 50 and 100 per cent level (G3 and G4) replacing palm oil showed increased body weight gain (P less than 0.01) and better feed conversion ratio (P less than 0.05) than G1 group. There was no significant difference in the feed intake among the different treatment groups. Profit per kg live weight in G3 (Rs.12.06) and G4 (Rs.11.14) was more than G1 (Rs.8.21) and G2 (Rs.6.57). The supplementation of omega-3 rich rapeseed oil had significantly improved the performance of broilers.

A study was carried on 24 piglets (Large White York Shire × Desi) of an average initial weight of 20 kg of three gender groups, barrows, boars and gilts consisted of eight pigs each, of comparable body weight fattened from 20-48 kilograms (growing) to 49-96 kilograms (finishing) to see the effect of gender on growth performance, nutrient utilization and carcass traits. When comparing feed intake at the growing stage, gilts consumed significantly more (P less than 0.05) feed than boars and barrows. There was no significant difference in average daily weight gain among barrows, boars and gilts in growing and finishing stage. Gilts had significantly higher (P less than 0.05) feed conversion ratio than boars in growing period and barrows in finishing period. Nutrient digestibility was similar except crude protein among groups. Fasting weight and weight after bleeding was significantly lower (P less than 0.05) in gilts with nonsignificant difference between barrows and boars. Sex has no significant effect on evisceration weight, dressing percentage and carcass length in pigs. Carcass backfat of barrows was significantly thicker (P less than 0.05) than that of boars and gilts, however, the loin eye area was significantly larger (P less than 0.05) in gilts than boars and barrows. There were no significant differences among groups concerning the proportions of ham, under cut, bacon and rib chop however, shoulder and loin percentages were higher (P less than 0.05) in gilts than boars and barrows.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.
