Effects on rumen pH and feed intake of a dietary concentrate challenge in cows fed rations containing pH modulators with different neutralizing capacity

Optimizing Nutrient Digestibility Through Fermentation of Mangrove (Sonneratia alba) Fruit with Aspergillus niger: Implications for Livestock Feed Quality Improvement

“…The ideal pH of the rumen ranges between 6.9 and 7.3, where such pH conditions can support the growth of rumen microbes (Souza et al 2022). According to Bach et al (2023), pH varies depending on the type of feed provided. Fermentation of Tithonia diversifolia with Aspergillus ficuum and Lactobacillus plantarum produced a pH of 6.72-6.85 (Pazla et al 2021a).…”

Improving the Rumen Molar Proportion of Glucogenic Volatile Fatty Acids with the Inclusion of Siam Weed (Chromolaena odorata) Meal in Pelleted Diet of Fattened Cattle

“…A high protein diet increases the rumen's buffer capacity, elevating ruminal pH (Lopes et al, 2023), and a high intake of easily fermentable carbohydrates lowers the pH (Humer et al, 2017). This happens when the removal rate of lactic acid and VFAs from the rumen and rumen buffering capacity cannot keep up with their production rate (Bach et al, 2023). The normal ruminal digestion of dairy cattle occurs when the rumen pH is between 6.0 and 6.5 (Lam et al, 2015), whereas Haerr & Drackley (2012) proposed a range value of 6.0-6.9 for cattle feed total mixed ration.…”

The effect of oral administration of zeolite on the energy metabolism and reproductive health of Romanian spotted breed in advanced gestation and post partum period

“…The progressive genetic improvement of dairy cattle has led to continuous increases in milk production capacity. This high milk production potential can only be achieved if the diet that cows are able to consume supplies sufficient energy and nutrients, primarily through the inclusion of concentrates ( Bach et al., 2023 ;). Unfortunately, this emphasis on concentrates has led to several issues, including a decrease in ruminal pH, resulting in ruminal acidosis and negative implications for the energy balance ( Khachlouf et al., 2018 ).…”

“…Various strategies have been explored to manage rumen pH levels. These include supplementing rations with neutralizing agents, yeast cultures ( Bach et al., 2023 ;), sodium bicarbonate, and zeolite. Using zeolite at a maximum quantity of 400 g/day/cow has proven to be an effective buffering agent for enhancing productivity in dairy cow herds ( Khachlouf et al., 2018 ).…”
