Supplementation of Graded Levels of an Ethanolic Extract from Rumen Liquor as a Prebiotic in Broiler Chicken Diets: Effects onFeed Intake and Growth Performance

Paper ID- AMA-29-06-2023-12391

We conducted the present work to determine the optimum dose of ethanolic extract of rumen liquor as a prebiotic for broiler chicken. Rumen liquor collected from the slaughterhouse was processed to precipitate a soluble fiber fraction. A growth trial was conducted for 42 days on 480 broiler chicks divided into four groups: CO, RL0.025, RL0.05 and RL0.10. The chicks were fed a maize-soybean-based pre-starter diet (1-14 days), starter diet (15-21 days), and finisher diet (21-42 days) supplemented with RL fraction at the rate of 0.0%, 0.025%, 0.05%, and 0.1% (w/w) for CO, RL0.025, RL0.05 and RL0.10 groups, respectively. Live weight gain was comparable for all groups till the starter stage. In the finisher stage, significantly higher growth, better FCR and PER were observed in RL-supplemented birds compared to the CO birds, with the best performance in the RL0.10 group. It is concluded that RL extract supplementation effectively improves the growth performance of broiler chickens without an increase in feed intake. However, supplementation at 0.10% (w/w) level in feed is more effective than lower doses in improving the growth performance of broiler chickens, which resulted in higher savings in rearing costs.

Supplementation of a Prebiotic Fraction Isolated from Rumen Liquor in Broiler Chicken Diets: Effects on Haematology, Hepatic Function Tests and Lipid Profile

Paper ID- AMA-29-06-2023-12390

The present research scrutinized the impact of replacing antibiotics from broiler chicken diets with rumen liquor fraction (RL) or xylooligosaccharides over haematological profile, liver function assay and lipid profile. Rumen liquor was collected from a slaughterhouse and processed to recover a soluble fiber fraction. Day-old broiler chicks (Ven Cobb-400 strain, n = 480) were grouped into four groups, namely CO (Unsupplemented), RL (0.05% RL), XOS (0.05% Xylooligosaccharides), and AB (Enramycin 0.0125%), with 6 replicates (n=20) per group. Six chickens per replicate were slaughtered for sample collection at 42 days age. Haemoglobin levels of the RL, XOS, and AB groups were significantly lower than the CO group. Total leucocyte count and eosinophils (%) were significantly higher in the XOS group. No significant difference was observed between dietary groups for the liver function assay. Significantly higher HDL cholesterol levels were observed in the prebiotic-supplemented groups, whereas significantly lower triglyceride and VLDL levels were observed in XOS-supplemented birds.

Influence of Maize Shank Size for the Colonization of Trichoderma viride under on farm condition

Paper ID- AMA-29-06-2023-12389

Trichoderma viride is a promising biocontrol agent against major soil-borne plant pathogens like Macrophomina, Fusarium, Sclerotium, and Rhizoctonia sps, which are causing significant crop losses ranging from 25 to 45 percent. The availability of viable spore inoculum under farm-level conditions is a significant constraint for the effective management of soil-borne diseases. In addition to recycling crop residues to enhance soil health, there is an emerging need for crop cultivation. To explore the substrate for on-farm production of T. viride, an investigation was made into the effectiveness of maize shank for on-farm multiplication. The studies on the spawning technique for multiplication of T. viride using different sizes of shank such as 0.5, 1, 2, 4, 6, 8, 10 cm and powdered form of shank revealed that the powdered shank inoculated with talc formulation (20 x 106 cfu/g) of T. viride @ 10 gram in 200g shank-based spawn with 40 % moistened was found to be effective for the colonization of T. viride 28 days after inoculation.

Images of ten rice genotypes consisting of Chithrakar, Kuliyadichan, TRY 4, ADT 53, ACK 14090, ACK 15004, ADT 45, ASD 19, IR 64, Bhavani were selected and subjected to various image processing machine learning tool for vision based classification. Using Grain analyzer, morphological features of rice seed such as length, breadth, thickness, geometric mean diameter, sphericity, surface area, weight and area were estimated. The mean data were subjected to PCA analysis in STAR software to reduce the dimensionality. The trait such as length, surface area, geometric mean diameter, area and weight contributed significant variation as they possessed positive values in both PC1 and PC 2. The predicted variables of PCA and visual, textural, spectral characteristics of rice seed image obtained from Image Analyser (LEICA) were subjected to various image processing process. The processed images were fed into the machine tools viz., Partial Least Square Regression (PLS) and Support Vector Machine (SVM) for vision based classification. Totally 2000 images were taken and 80 per cent images were used for training the model, 20 per cent images were kept for testing the model. By comparing accuracy, precision, recall and F1 score of both the methods, PLS gives better performance than the SVM classifier. By using these classifiers, genotypes could be identified based on morphological features, visual characteristics and textural characteristics, as the accuracy and prediction are reliable.

Exploring Genetic Variability, Correlation, and Path Coefficients in F2 Generation of Rice (Oryza sativa L.)

Paper ID- AMA-28-06-2023-12383

Prolonged flash floods in South and Southeast Asia cause substantial crop yield reductions, but improved breeding techniques enhance resilience. The F2 population derived from the cross between ASD 16 and the NIL of CO 51 Sub1 was evaluated to study genetic variability, trait associations, and direct/indirect effects on yield. The Indel marker ART 5 revealed distinct segregation patterns in progenies (Homozygous:22; Heterozygous:72). The investigation unveiled high PCV, GCV and heritability, accompanied by high genetic advances, in pivotal traits such as the number of productive tillers per plant, flag leaf length, number of filled grains per panicle, number of chaffy grains per panicle, and single plant yield. These findings indicate the prevalence of additive genetic effects and underscore the substantial contributions of these traits to the observed variability within the population. The results of the correlation analysis indicated a highly significant positive correlation between single plant yield and four important traits: days to fifty percent flowering, plant height, panicle length, and number of filled grains per panicle. The path coefficient analysis indicated that the number of productive tillers per plant exerted the most substantial positive direct influence on the single plant yield. Similarly, spikelet fertility, number of chaffy grains per panicle, and plant height demonstrated significant positive effects as well. The findings indicate that the selection of specific traits viz., plant height, panicle length, number of filled grains per panicle and number of productive tillers per plant can enhance breeding outcomes.
