Carcass, internal organs, duodenal digesta bacteria and economics of broilers fed dry African porridge (Tetraptera tetrapluera ) pod meal

A study was conducted to ascertain the potential of African Porridge pod meal as natural feed additive to improve broiler performance. Its effect on carcass, internal organs, duodenal bacteria and economic benefits were examined. One hundred and twenty (120) 1-day old mixed sex Ross chicks were randomly allotted to 4 dietary treatments (T1 – T4) containing 0.0, 0.25, 0.5 and 0.75%dry African porridge pod meal respectively. Each treatment was replicated three times with 10 birds per replicate in a complete randomized design (CRD). Feed and water were given ad libitum for 8 weeks. Dressed percentage was significantly reduced (P<0.05) by African porridge pod meal which posted 68.96 - 71.93% as against 76.96% by the control. The cut-parts were not improved significantly. Abdominal fat deposition, bile secretion were increased and pancreas enlarged (P<0.05)by 0.50 and 0.75 levels of African porridge pod meal. Feeding of African porridge pod meal did not alter the nutritional value and pH of the meat. The spice showed antibacterial activity against salmonella and E. coli in the duodenum. The economic benefit was not improved, but the same as the control. In conclusion, in terms of carcass yield use of African porridge pod meal could not be advocated, but considering its antibacterial effect it could be used at 0.25% to modulate the gut of broilers.

INTERNAL ORGANS CHAR ACTERISTICS OF NATIVE CHICKEN FED BY COCONUT OIL (Cocos nucifera) ON DIET. The research was carried to determine the internal organs characteristics of buras chickens fed coconut (Cocos mucifera) oil in diet. A total 100 unsexed buras chickens was used in this experiment. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 5 replications (4 hens each). The data were subjected to analysis of variance, when the treatments indicated significant effect it was continued Duncan’s Multiple Range Test. Five dietary treatments containing 0, 0.5%, 1 %, 1,5%, and 2% levels of coconut oil (CO) with five replicates were applied to chickens. Parameters measured were body weight, heart, liver, pancreas and gizzard weight. Result showed that CO in the ration significantly increased the body weight (P<0.01) but did not affect to heart weight, liver weight, pancreas weight and gizzard weight.(P>0.05) It can be concluded that coconut oil in the diet can’t increase the internal organ characteristics. We can gave the 2% CO in the diet for the best results. Key words: Internal Organs, Coconut Oil, Buras Chickens

The aim of this experiment was to identify the internal organs weight of 6-weeks old native chickens after treatment feed with l-threonine and l-tryptophan supplement. This experimental research used 128 native chickens aged one-week-old in a Completely Randomized Design with four treatments and four replications. The dietary treatments were T0 (control feed), T1 (T0 + 0.35% l-threonine + 0.10% l-tryptophan), T2 (T0 + 0.68% l-threonine + 0.17% l-tryptophan), and T3 (T0 + 1.00% l-threonine + 0.25% l-tryptophan). The variables measured included body weight, liver weight, pancreas weight, gizzard weight, and intestinal length. Statistical analysis showed that l-threonine and l-tryptophan significantly affected body weight, liver weight, pancreas weight, gizzard weight and intestinal length. Supplementing 1.00% l-threonine and 0.25% l- tryptophan to feed contributed to the highest body weight and internal organs weight of native chickens.

An experiment was carried out to determine the effect of different organic acids (OAs) on carcass yield and internal organ characteristics of broiler chickens. The OAs were ethanoic acid (acetic acid - AA), butanoic acid (butyric acid - BA), citric acid (CA) and methanoic acid (formic acid - FA). One hundred and fifty (150) day old AborAcre-plus chicks were used. There were five dietary treatments. Diet 1 which served as control (CON) contained no OAs, while 0.25% of AA, BA, CA and FA replaced palm kernel cake in diets 2 – 5. Each treatment was replicated three times with 10 birds per replicate, arranged in completely randomized design (CRD). Diets were both isoenergetic and isonitrogenous. The experiment lasted for 4 weeks during the finisher phase. Feed and water were given ad libitum. At the end of 4 weeks, 3 birds from each replicate giving a total of 9 birds per treatment were slaughtered for carcass and internal organ evaluation. Result from the carcass evaluation showed that dressed carcass, breast, thigh, wing and drumstick of OA treated groups were not significantly (P>0.05) different from the control. The backcut was significantly (P<0.05) heavier in control than in AA and CA. Abdominal fat in birds fed OAs was statistically similar to the control. The liver weight was significantly (P<0.05) reduced by BA and FA while the weight of spleen was reduced (P<0.05) by all the OAs. The caecum and the large intestine were significantly (P<0.05) enlarged in the control. There was non effect (P>0.05) on other internal organs.

PERFORMANCE OF BROILERS FED THE LAMTORO (LEUCAENA LEUCOCEPHALA) LEAF MEAL IN THE DIETS. The utilization of lamtoro (Leucaena leucocephala) leaf meal (LLM) in broiler diets was investigated employing 0, 5, 10, 15 and 20% levels substituted to the based diet (control). In this experiment, 100 birds were randomly allocated into five groups of treatments. Each treatment was repeated into four replications with five birds per each replication. The five dietary treatments were allotted to the birds in a completely randomized design. The birds were fed experimental finisher diets. Feed and water were provided ad libitum. Effect of LLM inclusion up 20% on feed intake (g), live weight gain (g) and feed conversion did not differ significantly (P ˃ 0.05). It may be inferred from these experiments that LLM up to 20% can safely be substituted to broiler based diet.Keywords: Lamtoro leaf, broiler, performance

Gut Ph

Feed additives such as enzymes, probiotics, prebiotics and acidifiers are few examples of suitable alternatives to in – feed antibiotics in animal agriculture due to the ban of antibiotic use. However, the Nigerian poultry industry still experiences cases of antibiotic use. The gut benefits of alternatives to antibiotics often culminate in improved growth performance but there are or may be certain gut responses that attribute to the observed performance of poultry birds. In order to ascertain this, an experiment was conducted to evaluate the effect of antibiotic administration and enzyme supplementation on gut pH and bacteria counts. One hundred and fifty day-old broiler chicks were randomly distributed to three dietary treatments having five replicates and 10 birds per replicate. The experiment lasted forty – two (42) days and was arranged as a completely randomized design. A maize- soybean meal diet not supplemented with antibiotic or enzyme served as the control. Birds fed diet II had antibiotic (Dicoxin plus ®) administered to them. Birds fed diet III had their diets supplemented with enzyme (Roxazyme G2G®). Results indicated pH of the crop to be significantly (P<0.01) reduced by feed additive. The pH of the Ileum was least (5.65) under antibiotic administration but was not significantly different (p>0.05) different that of birds fed control and enzyme supplemented diet. Gizzard pH was acidic but not significantly (P>0.05) across all the treatments. Lactobacillus and Coliform counts were significant (P<0.05) affected by feed additive addition. It can be concluded that feed additive impact on gut pH can influence the type and population of bacteria present in the gastrointestinal tract.

Abstract Feeding condensed tannin (CT)-containing diets and minimizing preslaughter stress have been reported to improve meat quality and food safety in small ruminants. An experiment was conducted to determine the effects of feeding sericea lespedeza (SL), a high-CT legume, and transportation stress on gut microbial counts and meat quality in goats. In a completely randomized design with split-plot, thirty-six uncastrated male Spanish goats (Age = 8 mo; BW = 26.0 ± 0.48 kg) were assigned to one of 3 dietary treatments (n = 12): ground ‘Serala’ SL hay (SER), bermudagrass hay (BG), or bermudagrass hay - dewormed goats (BG-DW) at 75% of intake, with a corn-based supplement (25%) for 8 weeks. At the end of the trial, goats were either transported for 90 min to impose stress or held in pens before slaughtering in two replicates. Hot and cold carcass weights were lowest in SER, highest in BG-DW, and intermediate in BG group (P < 0.01). Longissimus muscle initial pH was not affected by diet or stress; however, the L* values were lower in SER compared with BG or BG-DW (P < 0.01). Diet or stress treatment did not have a significant effect on rumen and rectal pH values or E. coli and coliform counts. Rumen E. coli counts were 0.32, 0.35, and 0.32 (SEM = 0.088) log10CFU/g, respectively, in SER, BG, and BG-DW groups. The SER group had the lowest aerobic plate counts (APC) in both rumen and rectum (P < 0.01). Rumen APC were 4.74, 6.74, and 6.95 (SEM = 0.420) log10CFU/g, respectively, in SER, BG, and BG-DW groups. The results indicate that diet and stress did not notably influence meat quality characteristics studied or gut E. coli counts in goats, although there is evidence that APC in rumen and feces can be reduced by feeding SL for 8 weeks.

This study was carried out to determine the effect of dietary supplementation of Cymbopogon citratus oil (LGO) on the performance and carcass characteristics of broiler chicks. A total of 250 one-day-old chicks of Ross 308 strain were divided into 5 treatments with 5 replicate per treatment of 10 birds in a completely randomized design. The dietary treatments include a control diet (T1) with no Cymbopogon citratus oil (LGO). LGO was supplemented at 0.1%, 0.2 %, 0.3 % and 0.4 % in diets 2, 3, 4 and 5 respectively. The experiment lasted for 56 days; feed and water were administered ad libitum. Results obtained revealed that average daily weight gain (ADWG), average daily feed intake (ADFI), average daily water consumption (ADWC) and feed:gain were significantly influenced by LGO (P˂0.05). Highest mortality was recorded in T1 (4.15 %) followed by T2 (1.71 %), T3 (0.50 %), none was recorded in T4 and T5 (P˂0.05). dressing percentage, carcass and relative organ weight were significantly different among the treatments (P˂0.05).There was no noticeable inflammation was observed on the liver, kidney spleen and other internal organs. It was concluded that LGO is rich in phytochemical constituents and can be safely included in the diets of broiler chicks up to 0.4 % level without causing any detrimental effect on the growth performance and carcass of birds.

Abstract The objective was to determine the functional and nutritional values of Corynebacterium glutamicum Cell Mass (CGCM) on growth performance and gut health of newly-weaned pigs. Forty newly-weaned pigs (21 d of age; initial BW 7.1 ± 0.4 kg) were allotted to 5 dietary treatments based on randomized complete block design with sex and BW as blocks. The lysine broth of CGCM (CJ Bio, Fort Dodge, IA) was homogenized by using French press and dried to obtain lysed CGCM. Dietary treatments were: basal diet with lysed CGCM at 0, 0.7, 1.4, 2.1%, and with 1.4% intact CGCM. Experimental diets were formulated based on nutrient requirements (NRC, 2012) and pigs were fed based on 2 phases (10 and 11 d for each phase). Titanium dioxide (0.4%) was added to phase 2 diets as an indigestible external marker to calculate nutrient digestibility. Feed intake and BW were measured at d 0, 10, and 21. Pigs were euthanized on d 21 to collect proximal and distal jejunal mucosa to measure TNF-α, IL-8, MDA, IgA, and IgG concentrations. Diets and ileal digesta were collected to measure AID. Data were analyzed by SAS using MIXED, REG, and GLM procedures. Overall, increasing daily lysed CGCM intake increased (P < 0.05) ADG (211 to 296 g) and ADFI (432 to 501 g). Increasing levels of lysed CGCM decreased (P < 0.05) MDA and changed (quadratic, P < 0.05) IgA (max: 4.90 ng/mg at 1.13%) and IgG (max: 3.37 ng/mg at 1.04%) in the proximal jejunal mucosa. Increasing daily lysed CGCM intake had quadratic effect (P< 0.05) of protein carbonyl (max: 6.3 μmol/mg at 4.9 g/d). Lysed CGCM potentially benefits growth performance and gut health of newly-weaned pigs by reducing oxidative stress and increasing immune response.
