This study assessed the effect of browse Plants feed formulation on Goat (Capra aegagrus hircus) rumen microbial activities and in vitro gas production in Red Sokoto goat (Capra aegagrus hircus) over a period of fourteen (14) weeks. Four selected browse plants- Afzelia africana (TAa) Detarium microcarpum (TDm), Daniellia oliveri (TDo) and Khaya senegalensis (TKs) -were used to formulate diets for animal feeding. Three groups of growing Indigenous Red Sokoto goats were assigned to each of the browse plant diets (BPD), while the control group was placed on a basal diet only. Rumen fluids were collected from the goats intermittently for three (3) consecutive periods, and analyzed for pH, methylene blue-reduction time (MBRT), nitrate reduction, cellulose digestion, glucose fermentation and sedimentation activity rate. The results showed that browse plant feed formulation did not have a significant (p > 0.05) effect on the pH value of the rumen contents. Significant (p < 0.05) reductions in MBRT, nitrate reduction, and glucose fermentation were observed in all treatments except the control diets. However, the period for cellulose digestion significantly increased in all the browse plant-supplemented diet treatments. Furthermore, the volume of gas produced was significantly reduced by 64% (TAa), 62% (TDm), 71% (TDo), and 74% (TKs) in goats fed with browse plants as dietary supplements compared to 7% in the control (Tc). Overall, this study demonstrated that browse plant feed has the potential to significantly reduce the volume of methane produced and released by ruminant animals into the environment.

The utilization of exogenous enzymes is a prevalent nutritional strategy in the poultry industry. However, their effectiveness when used in diets formulated with non-traditional agro-byproducts like cassava peel remains uncertain. From a practical standpoint, assessing the efficacy of these enzymes in such contexts is vital to achieving competitive performance outcomes while maintaining low production costs. This study assessed the supplemental value of exo-enzyme (Maxigrain®) in the utilization of cassava peel meal (CPM) by broiler finisher chickens in a 28-day feeding trial. Two hundred and forty, 4 weeks old Arbor acre broiler birds were randomly allocated to four experimental diets tagged as T1, T2, T3 and T4, which were formulated to replace maize at 0, 25, 50, and 75% inclusion levels respectively with supplementary enzyme (Maxigrain®). The birds were further subdivided into four replicates of ten birds each in a completely randomized design arrangement. At the end of the 4 weeks feeding trial, performance and carcass attribute indices were measured, while feces and blood samples were collected for nutrient digestibility and blood biochemical evaluations, respectively. Data on feed cost analysis were calculated using the prevailing current market price of feed ingredients. The result showed that average weight gain and feed intake were significantly affected (P<0.05) by dietary treatments. Birds on a 50% CPM enzyme diet had a significant (P<0.05) higher weight gain and feed intake followed by those on a 75% CPM diet as compared to the control group. Feed cost/kg weight gain significantly (P<0.05) decreased with increasing levels of enzyme-supplemented CPM. Profit margins generated were higher (P<0.05) in bird fed enzyme-treated CPM diet group. The apparent nutrient digestibility of the birds revealed a significant (P<0.05) variation in all parameters evaluated and increased with increasing levels of enzyme-supplemented CPM diets. Also, all blood metabolites evaluated were significantly affected (p<0.05) by enzyme supplementation to CPM-based diseases except for WBC, globulin, creatinine and cholesterol. Enzyme supplementation produced no significant (p>0.05) effect on live weight, carcass weight and dress weight across the treatments, however, birds at 50% dietary level had the highest mean values compared to other treatment groups. The cut weights of the wing, breast, thigh, back, liver, GIT and kidney were significantly (P<0.05) affected by the dietary treatments. Therefore, enzyme supplementation improved performance, nutrient digestibility, and carcass characteristics of broiler finishers fed cassava peel meal-based diet without any adverse effect and 50% inclusion gave an optimum performance on carcass and organ traits.


EFFECT OF CATERPILLAR (BUNAEOPSIS AURANTIACA) MEAL AS A REPLACEMENT FOR FISH MEAL ON CARCASS AND SENSORY EVALUATON IN BROILER CHICKEN

Nigerian Journal of Animal Production

An experiment was conducted to evaluate the effect of graded levels of Caterpillar (Bunaeopsis aurantiaca) as replacement for fish meal on carcass and sensory parameters of finisher broilers. A total of 150 four- week old broilers were randomly allocated to five experimental diets formulated to contain 0, 15, 30, 45 and 60% caterpillar meal. There were 30 birds in each treatment which was replicated three (3) times with ten (10) birds per pen in a completely randomized design. Throughout the experimental period, feed and water were provided ad libitum for all treatment groups. Data were collected on carcass and sensory characteristics of the birds. Results revealed that live weight (2380.74-2654.67 g), dressing percentage (84.54-86.14 %) and breast weight (18.17-21.34 %), and all the sensory parameters measured were not statistically (P>0.05) influenced by dietary treatments. The study concluded that up to 60% Caterpillar (Bunaeopsis aurantiaca) meal can be included as replacement for fish meal in the diets of finisher broilers without adverse effect on carcass and sensory parameters of birds.

An experiment was conducted to determine the impact of acidifier supplementation to a mixture of sun-dried cassava and sweet potato peels meal in diets of broiler finisher chickens on growth performance and cost implication. A total of 105, 28-day-old Arbor acres broiler chicks were randomly allocated into 4 dietary treatments containing 5 replications of 7 birds each in a completely randomized design. Diet T1 served as the positive control (PC) containing maize-soybean meal based diet, diet T2 served as the negative control (NC) containing 25% replacement of maize with sun-dried cassava-sweet potato peel mixture (CSPPM) in T1 diet, while diet T3 and T4 were formulated to contain 0.5% and 1% acidifier supplementation to NC, respectively. Results showed that final body weight and weight gain were significantly higher (p<0.05) in birds fed PC and 1% acidified CSPPM diets than those fed CSPPM based diet. Feed intake was higher (p<0.05) in PC and acidified CSPPM diets compare to those fed CSPPM based diets. Birds fed PC and 1% acidified CSPPM diets showed significantly (p<0.05) lower feed:gain compared to the group fed CSPPM based diet. Feed cost/intake and feed cost/gain were significantly higher (p<0.05) in control group than in other dietary treatment groups. Feed cost/kg gain reduced significantly (p<0.05) in birds fed acidified CSPPM diets than those fed PC and NC diets. Conclusively, CSPPM can replace maize up to 25% in broiler finisher ration with acidifier supplementation up to 1% inclusion level for improved performance at a lower feed cost/kg gain.

The need for sustainable management of cypermethrin, a widely used synthetic pesticide with significant ecological impact, calls for urgent concerns among environmental stakeholders. Therefore, in this study, the potential cypermethrin-degrading (PCD) bacteria were screened and identified from the soil samples collected from the Cowpea farm of Teaching and Research farm of Kwara State University, Nigeria. The bacterial strains were screened and isolated through enrichment techniques and identified using the standard phenotypic and molecular techniques. The potential for cypermethrin utilisation was determined in the cypermethrin-treated mineral salt medium. The three PCD bacterial strains isolated were PCD1 (Lysinibacillus fusiformis), PCD2 (Bacillus sonorensis), and PCD3 (Achromobacter sp.). Molecular characterization confirmed the identities and revealed high sequence similarity with known species. The accession numbers for these strains are MF973057 (PCD1), MF973058 (PCD2), and MF973059 (PCD3). The growth-dependent utilization of cypermethrin using the optical density values (OD 600 nm) showed the highest OD value on day six (PCD2: 0.60 and PCD3: 0.65) and day nine (PCD1: 0.80) respectively. The observed increases in optical density (OD 600 nm) affirmed their potential for cypermethrin degradation. While the strains exhibit promise in metabolizing cypermethrin, further research is needed to assess their suitability for bioremediation.

... Cassava peel is a cheaper and readily available agro-industrial by-product, farm waste or crop residue resulting from the processing of cassava roots for human consumption. Several studies have shown that cassava peel can be exploited as an alternative feed resource in the diets of monogastric animals in replacing high-energy cereals, particularly maize [12,13,10,14,15,16]. However, the use of cassava peel has largely remained underutilized as livestock feed due to its high level of cyanide, non-starch polysaccharides (10.0 -38.4%) often designated as fiber, high phytate content and low protein content ranging between 2.10 and 8.20%, which often limit their utilization in monogastric diet [17,13,4,14]. ...
