FERMENTATION OF BLOOD MEAL ABSORBED BY OIL PALM FRONDS WITH Bacillus amyloliquefaciens AND Lactobacillus plantarum
No full textThis study was aimed at improving the efficiency of blood meal (BM) use as feedstuff through the application of agricultural waste absorbance and fermentation technology. Blood was absorbed by oil palm fronds and fermented by using Bacillus amyloliquefaciens (BAF) and Lactobacillus plantarum (BLP) inoculants in 0, 60, and 120 hour incubation times. Quality was assessed by using Van Soest fiber analysis and in vitro digestibility trial on the best fermented product. Results showed that there was significant interaction effect (P<0.05) of inoculant type and fermentation times on the changes in fiber fraction of BM absorbed by oil palm fronds. Inoculant types were found to give significant effects (P<0.05) on ration digestibility rate and in vitro rumen condition characteristics. It was concluded that fermentation of BM absorbed with palm oil fronds with BLP in 120 hours resulted in BM with the best fiber fraction reduction, digestibility rate, and in vitro rumen condition characteristics. © 2023, Online Journal of Animal and Feed Research.

EFFECTS OF BIOSECURITY PRACTICES ON THE HEALTH MANAGEMENT SYSTEM OF POULTRY FARMS IN NIGERIA
No full textThe purpose of the study was to determine how Oyo State, Nigerian biosecurity strategies, affected the poultry health management system. The regional data were collected through a planned investigation. The 120 respondents were selected using random and purposeful sampling approaches. The analysis revealed that 43.3 of poultry farmers were between the ages of 31 and 40; the majority were men; 72.5 were married; 37.5 had been in farming for between 11 and 20 years, and 95.5 had one to six children. Most farmers (75.8) reported that raising poultry was their main source of income; 70.8 stated they got their information from the farmers' association; 95.0 stated burning birds reduced susceptibility to infectious diseases, and nearly all (99.2) stated keeping foot dips in place stopped the spread of infectious diseases. According to the regression analysis, there is a strong correlation between respondents' age, sex, marital status, agricultural experience, family size, source of income, and adoption of biosecurity methods in the research region. The greatest and most affordable way of infection protection can be found in biosecurity. Without appropriate biosecurity measures, no single disease prevention program will succeed. It is can be concluded that the introduction of additional biosecurity measures could be a significant boost to the prevention and spread of poultry diseases in the study area. © 2023,Online Journal of Animal and Feed Research.

Semen Cryopreservation Quality and Sperm Kinematics of Saanen Goats Using Different Diluents
No full textThe success of artificial insemination (AI) in small ruminants, especially goats, depends on the quality of frozen semen. Therefore, the current study aimed to determine the quality of various diluents, including tris-egg yolk, AndroMed®, and OviXcell®, on semen quality. The fresh semen samples from three male Saanen goats aged 1.5-2 years were collected and the mean individual motility of samples was recorded at 70. The cryopreservation quality of the semen was evaluated based on motility, viability, abnormality, and total sperm motility (TSM) indexes. The present laboratory experiment was performed with 3 treatments and 10 repetitions. The treatments in this study were T0 (tris-egg yolk), T1 (AndroMed®), and T2 (OviXcell®). The results showed no significant difference in the parameters of motility, viability, abnormality, and TSM among the treatment group. The kinematic parameters� average path length, velocity curved linear, and linearity showed a significant difference in all treatment groups. However, there were no significant differences among the three groups in terms of motility, progressiveness, distance curved line, distance straight line, average velocity path, velocity straight line, straightness, amplitude lateral head, beat cross frequency, and wobble kinematic parameters. Motility was higher in T2 than in T0 and T1, viability was higher in T1 than in T0 and T2, and abnormality was lower in T1 than in T0 and T2. In conclusion, the use of various diluents, such as tris-egg yolk, AndroMed®, and OviXcell®, can maintain the quality of frozen spermatozoa for over 24 hours, including motility, viability, abnormality, and TSM. Kinematic parameters obtained using CASA IVOS II can provide relevant information for various parameters using these diluents. © 2023, World''s Veterinary Journal. All Rights Reserved
The Effect of Sausage Tree Fruit (Kigelia africana) on Gonadal Development and Growth Performance of Oreochromis andersonii
No full textIn Zambia fish farms, Oreochromis andersonii is an important common indigenous fish species. Naturally, safe phytochemicals can effectively improve hsif reproduction performance and their production potential. Therefore, this study was conducted to determine the effect of Kigelia africana on the gonadal development and the performance of Oreochromis andersonii. A total of 96 male fingerlings were randomly assigned to four dietary treatments (D1-D4), and each treatment group had three replicates. The D1, D2, D3, and D4 groups were formulated to receive 0, 50, 100, and 150 g of powdered Kigelia africana/kg, respectively. The fish were fed the diets for 9 weeks, followed by the study parameter measurements at the end of the experiment. The highest mean body weight and gonadal weight were (29.8 ± 0.63 and 0.09 ± 0.010 g, respectively) for fish in the D2 group. There was no significant difference between the mean body weight of fish in different groups, but their mean gonadal weights differed significantly. The gonadal somatic index of fish differed significantly among treatment groups, with those in D2 having the highest mean value (0.36 ± 0.060). The highest mean standard length (103.3 ± 0.63 mm) and total length (126.0 ± 0.11 mm) of fish were observed for D1 and D2 groups, respectively. Additionally, the mean values for those parameters decreased with increasing Kigelia africana in the diet. The physicochemical parameters of water, including temperature and dissolved oxygen, ranged 16.8-23.1°C and 0.6-2.2 mg/L, respectively; these were generally at low levels considering the optimum requirements for this fish species. In conclusion, Kigelia africana improved gonadal growth and development but did not promote overall fish growth. The best gonadal growth/development results of Kigelia africana powder were observed at a level of 50 g/kg, which can be used as a performance booster in the aquaculture production of Oreochromis andersonii © 2023, World's Veterinary Journal.All Rights Reserved
AN INVESTIGATION ON AVAILABILITY AND EFFICACY OF ANTI-ANEMIC DRUGS FOR PIGS IN THE UKRAINIAN PHARMACEUTICALS
No full textAntianemic drugs are used to prevent anemia, majorly iron deficiency anemia. Drugs with such pharmacological action are especially relevant for piglets, as animals of this species at this age are particularly sensitive to iron deficiency. The present investigation aimed at studying the pharmaceutical market of antianemic drugs registered in Ukraine during 2017-2022. It should be noted that if the drug is registered, it has been checked for safety according to the food industry standards of Ukraine. In 2017, the national market of veterinary iron-containing drugs was represented by 13 drugs from the group QB03A �Antianemic drugs. Drugs of iron�, according to the �ТС-vet classification. The range of these drugs by 38 was provided by pharmaceutical products of Ukrainian manufacturers: "O.L.KAR-AgroZooVet-Service", "Pharmaton", "Brovapharma", "Experimental production of the Institute of Epizootology", "Biopharm", and "Vetsintez". Imported products (62 ) were represented by Pharmacosmos, Merial, Koofavet, "Vugen B&G", "Biovet Pulawy", "Interchem Verken De Adelaar", and "Bioveta". In general, the modern pharmaceutical market of veterinary drugs in Ukraine during 2017�2022 was sufficiently provided with antianemic drugs for pigs and mostly imported drugs. The percentage of antianemic drugs of Ukrainian production prevailed in 2020, however the imported drugs of this pharmacological group's was higher in 2022. It can be concluded that the drugs of non-Ukrainian production predominated among antianemic drugs in Ukraine during 2017-2022. Based on the obtained results, we can state that in Ukraine there is a need for the development and/or production of domestic anti-anemic drugs. They must be effective and ensure a reduction in the dependence of the national pharmaceutical market of drugs of this group on foreign manufacturers. © (), (). All Rights Reserved
IMPACT OF PHASE-FEEDING PROGRAMS ON PERFORMANCE OF BROILER CHICKENS IN NIGERIA
No full textPhase-feeding is the feeding of several diets for a relatively short period of time to specifically meet an animal�s nutrient requirements. The study evaluated the effect of different phase feeding methods on growth and carcass characteristics of broiler chickens. A total of 120-day-old chicks of the FIDAN strain were assigned to four dietary treatments of 30 birds each, 15 birds per replicate. Birds were fed at different phases: Phase 1 were fed broiler starter diet alone for 8 weeks; Phase 2 birds were fed starter diet from 0-4 weeks and 1st finisher diet from 5-8 weeks. Phase 3 birds were fed starter diet from 0-3 weeks, 1st finisher diet from 4-6 weeks and 2nd finisher diet from 6-8 weeks. Phase 4 birds were fed starter diet from 0-2 weeks, 1st finisher diet from 2-4 weeks, 2nd finisher diet from 4-6 weeks and 3rd finisher diet from 6-8 weeks of age. Result no significant differences (p>0.05) between the groups in body weight gain (2.91-2.47 kg/bird) and feed conversion ratio (2.03-2.34). Total feed intake was highest in phase 1 (6.70 kg/bird) followed by phase 2 birds (6.41 kg). Dressed weight in Phase 1 was significantly (p<0.05) higher than others, followed by Phase 2. Dressing percentage did not differ significantly (p>0.05) between the groups. Feed cost between treatments was however significantly (p<0.05) different, Phase 1 diet being costliest. Phase-feeding using phase 4 regime elicited reduced dietary cost without compromising optimal performance of the birds. © (2023). All Rights Reserved
Freight Mode Choice with Public Data from the United States
No full textThis paper investigates the selection of freight modes by shippers that require transportation for their shipments. A discrete choice multinomial logit model is used to understand the connectivity and integration between mode-choice and the regional socioeconomic environment. The 2012 Commodity Flow Survey and United States Census Bureau data are public sources used to estimate the corresponding model. Analytical results indicate that shipment characteristics, commodity and industry types, and regional socioeconomic attributes provide an enhanced representation of the economic linkages that determine mode choice at the regional level. Meaningful discussion and guidance is provided to understand this complex process
Intercomparison of Rainfall Estimates of Three Distributions for Computation of PFD using Rational Formula and SUH Approach
No full textPeak flood discharge (PFD) for a given return period is considered as one of the most important parameters for planning and design of hydraulic structures, river protection works, and development of integrated water resources management projects. This can be achieved by adopting various methods such as flood frequency analysis, rational formula, envelope curves and Synthetic Unit Hydrograph (SUH) approach. Out of which, rational formula is applied for estimation of PFD for ungauged catchments with catchment area less than 25 km2 while SUH approach is adopted for ungauged catchments with catchment area more than 25 km2. This paper aims to investigate the study on intercomparison of probability distributions for estimation of extreme (i.e., 1-day maximum) rainfall for computation of PFD by adopting rational formula and SUH approach for the Vadhavan Port Project (VPP). The annual 1-day maximum rainfall series is extracted from the daily rainfall data observed at Dahanu site during the period 1969 to 2019 and also used for estimation of rainfall. The probability distributions viz., Extreme Value Type-1, 2-parameter Log Normal and Log Pearson Type-3 (LP3) adopted in extreme value analysis of rainfall is evaluated through diagnostic test using root mean square error and accordingly LP3 is adjudged as the best fit for estimation of rainfall. The 1-day maximum rainfall obtained from LP3 is considered to compute the rainfall intensity by applying one-third rule of IMD (India Meteorological Department) and also used for computation of PFD through rational formula. In SUH approach, the areal rainfall, physiographic and SUH parameters of the ungauged catchments are considered for computation of PFD. The study suggests the 25-year, 50-year and 100-year return period PFDs at six locations within the study area using rational formula and SUH approach could be considered for design purposes while designing any civil and hydraulic structures in the VPP
CHEMICAL COMPOSITION AND IN VITRO GAS PRODUCTION OF Brachiaria decumbens HARVESTED AT DIFFERENT STAGES OF GROWTH IN THE HOT HUMID REGION
No full textThe study evaluated the effect of harvesting date on the chemical composition and in vitro gas production of the botanic fractions of Brachiaria decumbens grass. The botanic fractions (leaf, stem and whole plant) of the grass at two maturities (60 and 120 days) in a Completely Randomised Design with factorial arrangement. Samples of botanic fractions at the different harvest dates were chemically analyzed for dry matter (DM), crude protein (CP), fibre concentrations and in vitro gas production (IVGP) was measured at 3, 6, 9, 12, 24, 36, 48, 72 and 96 h to estimate the volume and rate of gas production. Short-chain volatile fatty acids, microbial protein production, in vitro organic matter digestibility, and metabolizable energy were estimated from established models. Organic matter, crude fibre, NDF, ADF and ADL increased (P<0.05) with increasing maturity whereas the reverse was so for CP and ash contents (P<0.05). Significant interactions (P<0.05) between harvest date and plant fraction were present for both �b� and �c� attributable to treatment effects. Potential gas production �b� elicited a negative response for all plant fractions across the two harvest dates as the values decreased linearly. The rate at which the gases were produced �c� also induced a negative response for the leaf and whole fraction but a positive one for the stem fraction. The nutrient composition and gas production characteristics of grasses harvested at day 60 offer a better potential as high quality forage for improved intake and digestibility. The leaf fractions performed relatively better based on the afore-mentioned methods of quality assessment at both maturity periods. © (2023), (Scienceline Publication). All Rights Reserved
RELATIONSHIP BETWEEN STEAMING UP WITH COLOSTRUM PRODUCTION AT DIFFERENT MILKING TIMES IN HOLSTEINFRIESIAN COWS
No full textAims of study was to determine the relationship between steaming up with colostrum production at different milking times. The animals used in this research were 36 pregnant Holstein-Friesian (HF) cows. The method used in this research was a case study. Samples were determined with purposive sampling. The selected animal was divided into two groups, T1 (control) and T2 (steaming up). The steaming up was done two weeks prior to calving. The total average of colostrum production from HF cows that were in T2 group was 11.96±2.40 liter/cow/day, while the mean value of colostrum production from HF cows that were in T1 group was 8.05±1.80 liter/cow/day. The average colostrum production that was collected at morning milking from cows in T2 group was 6.38±1.36 liter/cow/day and at afternoon milking was 5.58±1.11 liter/cow/day, significantly higher than T1 group which was 4.22±0.92 liter/cow/day at morning milking and 3.83±0.90 liter/cow/day. The result of the regression equation on morning milking is Y = 2.059 + 2.159x. This means that steaming up treatment can increase colostrum production by as much as 2.159 liters at morning milking. While the result of the regression equation on afternoon milking is Y = 1.753 + 2.078x. This means steaming up treatment can escalate the colostrum production as much as 2.078 at afternoon milking. That equation is used as the basis for estimating the relationship between steaming up with colostrum production at both milking times, with a correlation coefficient (r) between steaming up and colostrum quantity at morning milking is 0.692, which means the relationship is in the strong category. Meanwhile, the relationship between steaming up and colostrum yield at afternoon milking is 0.666, which means the relationship is also in the strong category. It was concluded that steaming up had a very significant effect at both milking times in Holstein-Friesian cows. © (2023), (Scienceline Publication). All Rights Reserved
