Agro-industrial by-products contain valuable components such as polyphenols that can play a significant role in producing milk with specific properties through rumen fermentation. In Egypt, the buffalo milk chain has a potential market, which is larger than that for cow milk, especially in small villages. Therefore, this study aims to explore different feed ingredients from agro-waste for enhancing the functional properties of raw buffalo milk including polyphenols, flavonoids, vitamins A, C, α-tocopherol, and conjugated linoleic acid (CLA) contents. For this purpose, thirty dairy water buffalo (Bubalus bubalis) with a weight of about 520 kg were randomly divided into five groups of six animals each. The first group was fed a basal diet (silage) without agro-waste, while the other four groups were fed the basal diet after replacing 25% of the diet with different agro-wastes including barley (snack/bakery waste), sweet potato/carrot, biscuit/cake waste and tomato pomace. The feeding experimental period lasted 90 days, then milk samples (n = 150) were collected. Our results show that adding sweet potato/ carrot or tomato pomace to the basal diet enhanced the contents of vitamins A, C, and phenolic compounds reflecting on the enhancement of the antioxidant capacity of raw buffalo milk. Concerning the CLA content, the milk samples collected from buffalo fed the basal diet fortified with tomato pomace and biscuit/cake waste had the highest CLA and α-tocopherol content. Therefore, this study recommends using the tested agro-waste ingredients for producing functional buffalo milk, especially for small-medium milk producers.

Агропромышленные отходы содержат ценные компоненты, такие как полифенолы, которые могут играть существенную роль в выработке молока со специфическими свойствами в результате рубцовой ферментации. В Египте цепь буйволиного молока имеет более крупный потенциальный рынок, чем коровьего молока, особенно в небольших деревнях. Таким образом, данное исследование нацелено на изучение различных кормовых ингредиентов от сельскохозяйственных отходов для повышения функциональных свойств сырого буйволиного молока, включая содержание полифенолов, флавоноидов, витаминов А, С, α-токоферола, и конъюгированной линолевой кислоты (CLA). С этой целью 30 молочных буйволов (Bubalus bubalis) весом приблизительно 520 кг были разделены на пять групп по шесть животных. Первая группа получала основной рацион (силос) без сельскохозяйственных отходов, в то время как остальные четыре группы получали основной рацион с заменой 25% рациона различными сельскохозяйственными отходами, включая ячмень (отходы снеков/хлебобулочных изделий), сладкий картофель/морковь, отходы печенья/пирожных и томатные выжимки. Экспериментальный период кормления длился 90 дней, а затем отбирали образцы молока (n = 150). Наши результаты показали, что добавление картофеля/моркови или томатных выжимок к основному рациону увеличивало содержание витаминов А, С и фенольных соединений, отражая усиление антиоксидантной способности сырого буйволиного молока. Что касается содержания CLA, то образцы молока, отобранные от буйволов, получавших основной рацион, фортифицированный томатными выжимками и отходами печенья/ пирожных имели наиболее высокое содержание CLA и α-токоферолов. Таким образом, данное исследование рекомендует использование тестированных ингредиентов сельскохозяйственных отходов для производства функционального буйволиного молока, особенно для мелких и средних производителей молока.
