Abstract During two feeding trials, the effect of dietary phytogenic mixture on the performance and oxidative stress biomarkers in the liver of broilers reared under thermoneutral conditions (TN) and heat stress (HS) was studied. A number of 60 Cobb 500 chicks/trial were sheltered in environmentally-controlled digestibility cages. On the 14 days of age, the chicks were weighted and assigned to four groups (2 groups/trial with 30 chicks/group). In the first trial, two groups (C-TN and PM-TN) were kept in thermoneutral conditions. In the second trial, other two groups were kept (C-HS and PM-HS) in heat stress (32 ±1 °C). The structure of diets was the same in both experiments. Compared with the control diet (C), the experimental diet (PM) contained the addition of 1% phytogenic mixture (bilberry leaves, peppermint leaves, fennel leaves and sea buckthorn meal). Irrespective of temperature conditions, dietary PM did not affect broiler’s performance. The dietary supplementation of PM delayed protein and lipid oxidation in the liver tissue of broilers in both trials by increasing the hepatic catalase, glutathione and superoxide dismutase activity.

Abstract A 63-day study that involved 20 growing West African Dwarf sheep with average live bodyweight of 7.44 ± 0.18 kgW0.75 was carried out to evaluate nutrients intake, nitrogen metabolism, weight gain and blood profile of sheep fed Pennisetum purpureum (PP) substituted with white morus alba leaves (ML). The sheep were allotted to 5 treatments of 4 sheep per replicate in a Completely Randomized Design experiment. Five diets fed to the sheep were formulated designated as T1 (100 % PP), T2 (75 % PP: 25 % ML), T3 (50 % PP: 50 % ML), T4 (25 % PP: 75 % ML) and T5 (100 % ML). DM ranged 89.03 - 90.16 % and highest (21.05 %CP) was obtained in T5. Nutrients intake, DWG and FGR were significantly (p<0.05) influenced. Highest DMI (250.38 gW0.75/day) and CPI (52.70 gW0.75/day) were observed in sheep fed T5. Highest N-balance (5.75 gW0.75) was obtained in sheep fed T5. Consequently, the best DWG (16.10 gW0.75g/day) and least FCR (15.55). Haematological and serum biochemical indices were within normal range for WAD sheep. Thus, sole feeding of white mulberry leave could offer a reliable source of protein for sheep.

Abstract Current nutritional strategies of livestock industry are focused on evaluating the effects of terrestrial sources rich in natural bioactive compounds that can be used in farm animal feed and the subsequent implications on the quality of resulting animal products. In this context, the present study aimed to characterize from a nutritional point of view some natural plants used as phyto-additives in poultry nutrition: oregano, mint, basil, sage, fenugreek, thyme, turmeric, cumin and rosemary. The results of this study on plants nutritional evaluation showed a varied proximate analysis. Of all the plants, cumin, fenugreek and basil were the richest source of crude protein. Thyme had a large ether extractives content, followed by rosemary, sage and cumin. The obtained results revealed that oregano has the strongest antioxidant capacity (849.77 mmols equiv. asc. acid; 863.57 mmols equiv. vit. E), the highest total polyphenols concentration (86.77 mg GAE/g) and lutein and zeaxanthin (304.23 μg/g) of the analysed plants. Nevertheless, all plants had high concentration of total polyphenols, except cumin, a large amount of xanthophylls and vitamin E. After oregano, sage and thyme have been noted for their antioxidant capacity and major antioxidant compounds. Basil and sage revealed the highest amount of essential trace elements.

Abstract The feed quality have direct/indirect impact on the blood profiles of animal and determines health status. Hence, this study was carried out to investigate the dietary effect of T. nilotica seed meal (TNSM) on haematology and serum biochemical indices of goats. 15 West African Dwarf goats with a similar age range of 12-18 months old and body/live-weight of 6.88±0.26 kg were randomly allocated to 5 dietary treatments with 3 goats per replicate in a Completely Randomized Design arrangement for 12 weeks. Unprocessed TNSM were collected, screened and milled and were used to replace palm kernel cake at 20% (diet B), 30% (diet C), 40% (diet D) and 50% (diet E) replacement levels in a complete concentrate diets while diet A (control diet) had no T. nilotica. Nutrient composition, intake and animals' blood samples were assessed. Results revealed that all parameters observed were significantly (p<0.05) different. At 20%, DWG, FGR were best. PCV, RBC, Hb values of the goats decreased with increased with replacement level of PKC with TNSM. It could be concluded that TNSM could serve as protein source in place of PKC in goat diet up to 20% without any adverse effects on growth and health status.

Abstract The purpose of this study was to investigate the effect of synbiotic and organic acids on oxidative stability of breast broiler meat. The experiment consists on 120, 2 days old Ross 308 chicks, housed in metabolic cages (6 chicks/cage). A 2 x 2 factorial arrangement was considered with 4 treatments and 5 replicates (30 animals per group). Two different levels of synbiotic (0 and 10 g/kg) and two different levels of organic acids (0 and 1.5 g/kg) were added to the standard diets in order to constitute the four experimental diets. For further analysis, breast meat from 6 animals per group were collected in 42nd experimental day. No significant differences were noticed for any oxidative parameter measured in breast samples except TBARS (significant decreased values for OA supplemented groups), at the end of experiment. After 4 days of refrigeration (4°C), the secondary oxidative products (panisidine, TBARS) were significant smaller for E groups, compared to C. After 7 days of refrigeration (4°C), the OA groups had significant smaller values for primary (CD) and secondary oxidation products. Synbiotic and organic acids supplements presented positive effect on meat quality by increasing oxidative stability of breast meat during storage.

Abstract The composition of gastrointestinal tract microbiota can be changed by dietary manipulation, to prevent gut health issues and to promote animal performance. This study was conducted to investigate the effects of rice bran and alfalfa meal on growth performance and intestinal microbiota in broilers. A total of 252 Cobb 500 broilers, aged 14 days, were randomly assigned into 3 groups: control (CON), 5 % rice bran (RB), 5 % alfalfa meal (AM), and housed in an environment-controlled hall 42 days. Throughout the experimental period, grow performance parameters were monitored and at the end relative weights of internal organs were measured. Samples of intestinal content were collected for bacteriological determinations. Feed intake, daily weight gain and viability were not significantly affected by the dietary supplements. Alfalfa meal and rice bran decreased the populations of Escherichia coli and staphylococci in small intestine content, and Enterobacteriaceae, Escherichia coli and staphylococci in caecal content of broilers. The count of lactobacilli in both small intestine and caecal content registered a significantly increase in experimental groups, compared to CON group. Supplementation of diets with rice bran and alfalfa meal tended to increase the population of beneficial bacteria and inhibit the potential pathogens.

Abstract In this study, an experiment was conducted to investigate the effects of two levels of Bacillus subtilis ATCC 6051a (BS), respectively Bacillus licheniformis ATCC 21424 (BL) administered as direct-fed microbial DFM probiotic bacteria on plasma biochemical profile of weaning piglets fed diets. A total of 100 piglets, 30±3 day-old, with initial average body weight (BW) of 8.53±0.17 kg were randomly distributed to 5 homogeneous groups (C, E1-BS 1%, E2-BS 3%, E3-BL 1%, E4-BL 3%,), 2 replicates/group with 10 piglets/pens, for 16 days of biological trial. The doses used were: 1% low dose in a concentration of 1.6 x 109 CFU spores g-1 feed, and 3% high dose in a concentration of 4.8 x 109 CFU spores g-1 feed. Results showed that BS supplementation affected plasma concentration of GGT (P<0.017), TG (P<0.048) and Mg (P<0.0001). No effect (P>0.05) as diet*day interaction on plasma metabolic profile was observed. In conclusion, administration of Bacillus spp. maintains the concentration of blood plasma parameters within the physiological ranges, without affecting the piglet’s health status.

Abstract The effect of feeding a diet containing 25% millet grain on performance and plasma metabolic profile was evaluated in weaned piglets during 21 days trial. A total of 40 pigs with an 8.14±1.08 kg average body weight (BW) was weaned at 28±3 days of age and divided into the control group (C) and the experimental group (M). The C group (n=20) received a conventional diet based on the corn-triticale-soybean meal while in the M group (n=20) received 25% millet grain cv. Marius replaced triticale (2 replicates per group). At the end of the post-weaning period, the performances (BW; average daily feed intake, ADFI; average daily gain, ADG; feed: gain ratio, F: G ratio) and plasma metabolic profile (lipid, protein, enzyme, mineral) were evaluated. A slow, but not significant increase was observed for the BW (+6%), ADG (+12%), ADFI (+5%) and F: G ratio (+7%) of pigs fed M diet. No effect (P>0.05) of dietary treatment on plasma metabolic profile was observed. However, the concentrations of triglyceride (-15%, P=0.089), total cholesterol (-14%, P=0.060) and aspartate aminotransferase enzyme activity (-16%, P=0.095) tended to decreased while inorganic phosphorus (+11%; P<0.04) had increased in the M vs. C diet. The present study indicated that the replacement of 25% millet grain to triticale in weaned piglet’s diet, maintains the performances and blood plasma parameters within the physiological ranges, beneficial to the health status.

Abstract The influence of genotype (GTY) and 20-week body weight (PW20) on full-sexual maturity (FSM) productivity and hatching traits were investigated on two parent-stock layers in Ibadan, Nigeria. Data were obtained on twenty-two batches of BOVAN NERA (BN) and ISA BROWN layers (IB) each, between 2009-2019, from a breeding company in Ibadan. These were grouped based on strain and 20-week body weight. Experimental design was randomized block design (RBD). Data were subjected to general linear model (GLM) factorial and Tukey’s HSD, α=0.05, procedures of Statistical Analytical Systems® (SAS, 2002) software. BN had better pullet weight (P<0.05, ds=0.88), while IB possessed higher hen-day egg production, persistency of egg production and pullet day-old chicks hatched (P<0.05, ds=-0.86 to -1.44) at FSM. The 20-week low weight birds required intensive skillful management for compensatory weight-gain to FSM, while egg weight was higher in 20-week high weight class at full maturity (P<0.05, ds=0.06 to -1.19). Genotype by 20-week pullet-weight interaction revealed better genetics of BN genotype on compensatory growth between 20th week and FSM, and on PFM (P<0.05, ds=0.24 to 1.62). The better HDF and P80 (P<0.05, ds= -1.73, -1.61) of medium weight IB genotype signals its genetic ability for higher percent day-old chicks production (P>0.05, ds= -0.72 to -1.11).

Abstract The study aimed to isolate, identify, preserve and evaluate the quantitative level of the Lactobacillus strains from gut content and faeces of weaned piglets, 30-107 days old; to test the viability of these strains preserved at 4°C and room temperature. Lactobacillus strains were isolated, phenotypically identified and preserved from gut content and faeces of 20 weaned piglets. Identification was performed by morphological, cultural and biochemical character examination, using apiwebTM and ABIS online software. Lactobacillus spp. from intestinal content and faeces (106 – 109 CFU/g) and the viability of strains preserved at 4°C and at room temperature were also determined (from 38 days to 4 months). Twenty-six strains of L. acidophilus, L. fermentum, L. plantarum, L. salivarius and L. delbrueckii ssp. delbrueckii, from gut content and faeces of weaned piglets were isolated, phenotypic identified and preserved. Of these, L. fermentum, L. delbrueckii ssp. delbrueckii and L. acidophilus biotype 2 isolates were technologically and ecologically suitable for continuing the testing of probiotic traits.
