Evaluation of the effects of green tea extract as a dietary supplement in sheep on gas production, volatile fatty acids, and digestibility.

Background And Aim: Phenolic tannins, which are ubiquitous in plants, exhibit diverse biological activities and have drawn significant attention for their potential impact on ruminant nutrition and health. Although phenolic tannins have beneficial and detrimental effects on rumen fermentation, their precise influence remains poorly understood. This study aimed to explore the effects of varying doses of green tea extract (GTE) on rumen fermentation parameters through an trial using sheep rumen liquids.

Effects of dietary black cumin ( L.) meal on performance, blood metabolites, and digestibility in a rice straw-based diet of fattening Garut lambs.

Background And Aim: During black cumin oil production, black cumin meal (BCM) is produced as a by-product. This study investigated the potential use of BCM to partly replace concentrate in a rice straw-based diet of fattening Garut lambs.

Materials And Methods: Twenty-eight heads of male Garut lambs aged approximately10 months with an average initial body weight of 20.

Effect of green tea dust as a dietary additive and anthelminthic on performance, digestibility, and fecal egg counts in Priangan ewe lambs infected with Strongyles worms.

Despite green tea dust (GTD) is a by-product of green tea fabrication, it has the potential as natural additive and anthelmintic in ruminant diets due to its high protein and bioactive contents. This study aimed to compare the effect of 3 different doses [0% (control), 0.75% (GTD-0.

Ovicidal activity and cytotoxicity of ethanolic extract of turmeric () and green tea () to treat digestive parasite of sheep.

Background: The Trichuris eggs are collected from naturally infected sheep. Natural antihelmintics such as herbal medicines are needed as an alternative, such as natural compounds from endemic plants.

Aim: This present study aims to evaluate the ovicidal activity and cytotoxicity effects of ethanolic extract of (EECL) and (EECS) as a biological anthelmintic against the egg of .

Biochemical Properties of Black and Green Teas and Their Insoluble Residues as Natural Dietary Additives to Optimize In Vitro Rumen Degradability and Fermentation but Reduce Methane in Sheep.

Black (BTL) or green (GTL) tea and their spent tea (STL) leaves can be used as natural dietary additives for ruminants. Experiment 1 used a 3 × 2 × 2 factorial arrangement, with four replicates ( = 4) to test the effects of three different inclusions of tea leaves at 0 (control), 50, and 100 g/kg DM of two different tea types (BTL and GTL) in two different total mixed diets containing either ryegrass hay (RH) or rice straw (RS) on in vitro rumen organic matter degradability (IVOMD), volatile fatty acids (VFA), pH, ammonia (NH), and methane (CH) outputs over a 24 h incubation time. Experiment 2 followed a 3 × 2 × 2 factorial arrangement, with eight replicates ( = 8) to study the impacts of three different STL inclusions at 0, 100, and 200 g/kg DM of two different STL types (black and green) into two different total mixed diets containing either RH or RS on the same in vitro measurements.

Chemical composition, plant secondary metabolites, and minerals of green and black teas and the effect of different tea-to-water ratios during their extraction on the composition of their spent leaves as potential additives for ruminants.

This study characterized the chemical composition of green and black teas as well as their spent tea leaves (STL) following boiling in water with different tea-to-water ratios. The green and black tea leaves had statistically similar (g/kg dry matter (DM), unless stated otherwise) DM (937 vs 942 g/kg sample), crude protein (240 vs 242), and ash (61.8 vs 61.
