How buffaloes let down milk
Perinatal physiology and welfare in water buffalo: calving, mother-calf bonding, lactation, and postpartum disorders.
Overview
Mota-Rojas D et al.. Front Vet Sci 2026 · PMID 42707960 · DOI 10.3389/fvets.2026.1913756
Most buffalo milk is stored deep in the udder and released only when oxytocin is released, for example by suckling.

5. Actual results
- Results
In buffaloes about 90-95% of milk is stored in the alveolar fraction of the udder and is only available after milk ejection induced by oxytocin and myoepithelial contraction; oxytocin release is triggered by teat stimulation (e.g. suckling).
- Absolute risks
not applicable
- Authors' conclusion
Understanding peripartum mechanisms supports welfare and productivity in buffalo systems.

9. Assessment of the statistical interpretation
Not applicable.
10. Relevance to the specific claim
Explains why oxytocin is used in buffaloes (milk let-down when the calf is absent) and confirms that oxytocin releases stored milk rather than creating lactation.
11. Independent contrary findings
I-INTA-05 (oxytocin misuse documented in India).
12. Transferability to Germany and Europe
Relevant to Egyptian buffalo dairying.
13. Overall methodological judgement
Supports the existing physiology assessment.

14. Open questions
Egyptian survey data on oxytocin use.
15. Linked fact checks
- Cows naturally lactate seasonally (after giving birth), but dairy cows are injected with oxytocin all year round so that they keep producing milk; such milk is 'induced, not real'. – Studies contradicting or limiting the claim
