Evaluating the effects of direct-fed microbial supplementation on the performance, milk quality and fatty acid of mid-lactating dairy cows.

Background: The objective of the experiment was to investigate the effect of a mixture of direct-fed microbial (DFM) on feed intake, nutrient digestibility, milk yield and composition, milk fatty acid and blood parameter in crossbred mid-lactating cows.

Methods: Twenty-four crossbred Holstein cows (body weight = 650±15 kg; days in milk = 100±20; daily milk yield = 25±3 kg) were used in a completely randomized design with three treatments: (1) CON, without DFM; (2) LS, inoculation with Lactobacillus fermentum (4.5 × 10 CFU/day) plus Saccharomyces cerevisiae (1.

Effect of dietary leaves and branches on milk yield, quality, antioxidant activity and fatty acid profile, and blood parameters of Najdi dairy goats.

To investigate the effect of tree leaves and branches as a partial replacement of forage on milk yield and components, blood and rumen parameters of goats, 16 Najdi goats were used in a completely randomized design with 2 treatments (CON, without ; CE, contains ). The basic ratio consisted of 60% concentrate and 40% forage. In treatment CE, 22.

The Effect of Three Levels of Concentrate and Grain Processing on Feeding Behavior, Nutrient Digestibility, Blood Metabolites and Fecal pH Of Turkmen Horses.

The aim of this study was to investigate, the effect of different levels of concentrates and grain processing on feeding behavior, nutrient digestibility, fecal pH and blood metabolites in the horse. Sixteen 5 to 11 years old Turkmen horses with an initial body weight 433±50 kg were used in this experiment based on completely randomized design. Four treatments were studied, in three treatments were used 20, 25 and 30% of concentrate containing processed grains (A20, A25 and A30, respectively), and in one treatment was used 25% of concentrate containing whole grain (B25).

Lactobacillus plantarum as feed additive to improvement in vitro ruminal biofermentation and digestibility of some tropical tree leaves.

Aim: This study was performed to investigate the effects of Lactobacillus plantarum (LP) on the in vitro gas production (GP) kinetics and ruminal fermentation parameter of three species of tropical forage Ziziphus mauritiana, Acacia victoriae and Moringa oleifera.

Methods And Results: Treatments were (i) Z. mauritiana (Z) without LP (-ZLP), (ii) Z.

The Positive Impact of Increasing Feeding Frequency on Feed Intake, Nutrient Digestibility, and Blood Metabolites of Turkmen Horses.

To determine the effects of feeding frequency on nutrient digestibility and blood metabolites in horse, 16 Turkmen horses were used with weight of 430 ± 46 kg and age of 7 ± 1.8 years. Four feeding frequencies with 2 (M2), 4 (M4), 6 (M6), and 8 (M8) meals per day were used for a period of 28 days.
