| description | The diagnosis of unstable non-acid milk (UNAM) in Brazil is overlooked due to the lack of information about this
problem available to dairy farmers, mainly in the North region of the country. This report describes the occurrence of UNAM in
three dairy farms of family farmers in northern Tocantins state, Brazil, who use animal feed based on Urochloa brizantha without
mineral supplementation. The animals had been subjected to a poor feeding practice, with low quantity and quality, due to the dry
period in the region and inappropriate nutritional management. Fourteen animals that presented alterations in milk characteristics
were subjected to 72% alizarol test, California mastitis test, strip cup test, somatic cell count (SCC), boil test, physical-chemical
and microbiological analyses, and search for undesirable substances. The time of lactation, udder health, and serum glucose level
of animals, and soil and forage quality were also evaluated. The results showed 42% animals diagnosed with mastitis, 21% of
them with clinical and 21% with subclinical mastitis; and 78% of animals with samples positive for the alizarol and boil tests, and
Dornic acidity between 14° and 18°, characterizing positive cases for UNAM. Only one animal presented SCC above the limit
established by the Brazilian legislation. The animals presented undamaged teats and no alteration in glycemia. Changes in nutritional
management were recommended and done and the alizarol tests were redone after 14 days, showing all negative results for UNAM.
The conclusion is that incorrect nutritional management is the main cause of UNAN in the studied cases. |
