Does adoption of superior Murrah buffalo germplasm pay off? evidence from a causal impact study in Haryana, India.
Article in Frontiers in genetics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Buffaloes play a pivotal role in sustaining rural livelihoods, milk production, and nutritional security in South Asia, where genetic improvement remains a critical pathway to enhance productivity and profitability. Despite decades of breeding efforts, limited empirical evidence exists on the socio-economic impact of disseminating superior germplasm under structured progeny testing programs. This study employed a quasi-experimental design to evaluate the effects of the Central Institute for Research on Buffaloes (CIRB) Murrah superior germplasm disseminated under the Field Progeny Testing (FPT) program of the Network Project on Buffalo Improvement (NPBI) in Hisar district, Haryana, India. Treatment households were defined as adopters of CIRB superior germplasm, while non-adopters from comparable control villages, located approximately 40-50 km away to avoid spill-over, served as the control group. A total of 200 respondents (100 treatment and 100 control) were selected through a combination of purposive and random sampling. Data were collected using key informant interviews, focus group discussions, and structured household surveys, and analysed using doubly robust econometric approaches, including Inverse Probability Weighted Regression Adjustment (IPWRA), Propensity Score Matching (PSM), and Coarsened Exact Matching (CEM). Our findings suggest that calf birth weight, age at first calving, dry period, average daily milk yield, and cost of artificial insemination significantly influence the net income of buffalo-rearing households. Adoption of CIRB Murrah superior germplasm through the FPT program led to a significant higher annual net income by $405.94 per buffalo, average daily milk yield by 1.53 kg, and calf birth weight by 5.53 kg, while reducing Age at First Calving (AFC) by 2.94 months and shortening dry periods by 1.83 months in comparison with control group. The study further indicates that efficient reproductive management and affordable AI services are critical for realizing the full economic potential of buffalo herds. Consequently, the findings emphasize that targeted dissemination of superior germplasm combined with technical guidance on feeding, breeding, and health management is essential for enhancing productivity and profitability in dairy systems.
