Digital technology-enabled structural transformation and market of agricultural commodities
The agricultural sector has undergone different transformation phase which has led to improved proficiency, yield, and productivity. The upsurge of technology in agriculture could be the most transformative agent. This is because agricultural innovation will not only transform farming mechanisms but as well change the entire supply chain. Technology adoption in agriculture will positively influence farming operations and control input supplies, processing and retailing, price, and sales of agricultural commodities. Against this backdrop, this study empirically investigates the point of sales where the deployment of digital technology becomes significant. The study utilised Wave 4 (2018/2019) of the Living Standards Measurement Studies (LSMS), Integrated Survey on Agriculture (ISA) for the empirical analysis and applied the multinomial logit regression to answer the research question. The result shows that across various points of sales, technology adoption is significant for all the actors. However, though significant for all actors in the sale chains, the estimated coefficients slightly differ. The study concludes that there is a need to lower the cost of digital technology, such as the cost of a mobile phone and internet usage. To lower the cost of a mobile phone and the internet, and to enhance accessibility, especially in rural areas, the government and donor agencies need to invest in infrastructure to foster healthy competition in the telecommunication industry. This will lower the cost of a basic monthly data plan, because, with the current rate of mobile data plans and the speed of exhaustion, not many farming households, especially those in rural communities can afford it. Besides, taxes on ICT (e.g mobile phones and internet) tools which are in most cases, excessively high to afford should be lowered. Similarly, there should be support for public internet access points (e.g., building of masts in all localities), and digital training for rural farmers to foster technology adoption.
NON-GENETIC FACTORS AFFECTING MILK FAT PERCENTAGE UNDER SMALLHOLDER DAIRY SYSTEM IN INDIA
Crossbred cows' milk fat percentage data were collected from the Bharathi Agro-Industrial Foundation, Pune. The phenotypic data collected were from smallholder dairy systems from six states from 2016 and 2022. The data were subject to quality control and R statistical software was used to find the significance among the non-genetic factors affecting the milk fat percentage. The overall mean milk fat percentage was 3.83±0.81 among the crossbred cows. The mean values for different years ranged between 3.47±0.24 and 3.92±0.88, whereas the mean values for the three seasons were 3.82±0.79, 3.82±0.82 and 3.86±0.82 respectively. The later stage of lactation had a higher mean of 3.98±0.78 as compared with 3.57±0.82 during early lactation. A significant difference (P<0.001) was noticed among all the non-genetic factors considered for the present study. The results will be useful to study the performance of crossbred under different environmental conditions.
PROSTHETIC REHABILITATION OF A SOFT-SHELL TURTLE
A softshell turtle was presented with a history of vehicular collision. Clinical examination revealed shell fracture in the carapace as well as hind limb paralysis. Turtle was bright and alert and its excretory system was also functional. External fixation was done using the adhesives to fix the carapace. As the turtle was trying to move with its fore limbs hence it was decided to place the prosthesis to support its hind body and further movement. Supportive medicines and physiotherapy were also given to revive the normal functions. In this case, internal organs were not injured which made the turtle to survive the trauma. The practice of prosthesis is common in mammals but we tried the same in the reptile which proved to be successful.
BIOCHEMICAL CHANGES IN COW URINE AND DUNG BASED BIO-PESTICIDE FORMULATIONS, AND ITS EFFECT ON TICK CONTROL IN CATTLE
Bio-pesticide or Biological pesticides are derived from natural materials such as animals, plants, bacteria, and certain minerals. It is less toxic and reduces the pollution problems caused by conventional pesticides. The present study studied biochemical changes in cow urine and dung-based six (T1, T2, T3, T4, T5 and T6) different bio-pesticide formulations and their efficacy on cattle tick control. The results revealed that N2, CP, Urea, Uric acid, hippuric acid and creatinine increased significantly over fermentation. In tick control, results revealed highest tick mortality (%) in T6 (53.25±0.96) as compared to T5 (46.08±0.96), T4(42.26±0.96), T3(33.44±0.96), T2(28.41±0.96) and T1(22.77±0.96), respectively. However, the cow urine and dung-based formulations had a significantly (P<0.01) higher effect on tick mortality (42.54±0.51%) as compared to heifers urine and dung-based formulations.
Effect of supplementation of different Organic Trace Minerals on Production Performance, Immune Response, Carcass characteristics and Cost Economics of Commercial Broilers
An experiment was conducted to investigate the comparative performance of commercial broilers fed KemTrace (mineral propionate) with other organic minerals. The feeding trial was conducted for a period of six weeks with 672 chicks allotted to seven experimental groups each with 12 replicates and each replicate consisting of 8 birds in a completely randomized design. The diets of the treatments were : T1-Basal diet with Blend A (Inorganic- sulphates, oxides and carbonates) @1000gm/mt; T2-Basal diet with Blend B (Proteinates) @500 gm/mt. ; T3- basal diet with Blend C (Propionates with antioxidants)@250 gm/mt.; T4- Basal diet with blend D (same as T3 but produced in different process) @350 gm/mt.: T5-Basal diet with Blend E (Propionates, Fumarates with antioxidant) @250gm/mt.: T6-Basal diet with Blend F (Propionates, Fumarates with antioxidant) @500 gm/mt.; T-7 Basal diet with blend G (Butyrates, Propionate, Fumarates with antioxidants) @500 gm/mt of feed. Parameters like growth performance, carcass yield, immune status and trace mineral retention in organs were observed in the broilers. The collected data were analysed using SPSS software Programme version 17.0 and interpreted. The commercial broilers supplemented with metal propionate form of organic mineral performed better than other organic mineral supplementations on growth performance and immune response. Metal propionate form of organic mineral supplemented broilers also showed significantly higher performance on carcass quality and cost economics than other organic mineral supplementations.
