الملخص EN

A study was conducted at Deir Al-Hajar Research Station for Shami Camels, Administration of Livestock Research, General Commission for Scientific Agricultural Research (GCSAR) during 2019 and 2020 to find the relation between vitamin c concentrations in milk, and either stage of lactation, parity (lactation number) or the presence of mastitis.

For this purpose, thirty lactating Shami camels from different parties were used.Milk samples were collected monthly over one entire lactation season lasting 11 months.

The concentration of vitamin c was 35.01±9.81 mg/l milk during considered parities without significant differences in its concentration.

However, vitamin c concentration was affected by lactation month P<0.0.5, and the values ranged between 18.99 and 53.03 mg/l milkduring lactation.

An evident decline in vitamin c concentration in camel milk appeared with positive interactions for the California test.

The average concentration of vitamin c in milk produced from healthy and infected udders was 35.01±9.81 mg/l and 22.99±1.30 mg/l, respectively.

It has been concluded that vitamin c in milk is crucial indicator of udder health status
