This study was designed to evaluate the effect of substituting alfalfa hay with graded levels panicum maximum without or with graded levels of spirulina supplementation on rumen fermentation and nutrient degradability. The evaluation was achieved through an in vitro study, rumen fluid was obtained from adult sheep aged 2 years (fed clover hay), immediately after slaughter. Experimental diets were formulated as isonitrogenous and isocaloric and contained 40% forage.

- Camels' Feeding Behavior
- : The study investigates how camels (lactating) select between high-protein alfalfa and high-energy barley while grazing in a desert environment, examining their ability to meet nutritional needs. -
- Methodology
- : Eighteen camels were divided into three groups to graze on either alfalfa, barley, or a mix of both over two one-month periods. Energy expenditure was monitored using heart rate monitors calibrated with an oxygen consumption system. -
- Findings
- : Camels showed better forage intake and digestibility with barley in the first period, but overall energy balance favored barley grazing. Despite this, camels grazing on alfalfa produced higher milk yields compared to those solely on
Article Synopsis
- The study investigates using quinoa as a more affordable alternative feed for ruminants, evaluating its nutritional benefits and overall performance compared to conventional clover hay.
- In experiments, quinoa showed a good protein content of about 18.6% and suitable fatty acids, leading to positive outcomes regarding nutrient absorption.
- While replacing clover hay with quinoa did not significantly alter gas or methane production in the diets, it was found that quinoa could effectively replace up to 45% of clover hay without negative impacts on livestock health.
High prices of corn grains due to their shortage in some regions force researcher to explore nonconventional alternatives. Therefore, the present study aimed to evaluate the effect of replacing corn grains at 25% (dry matter (DM) basis) with date press cake (DPC) without/with exogenous enzymes at 2 L/ton feed in diets of Barki sheep (24 rams divided as 6 rams/treatment) and Egyptian buffaloes (16 buffaloes divided as 4 buffalo/treatment). Each experiment was conducted under 4 treatments regime: control diet containing only corn grains, T diet where the control diet supplemented with exogenous enzyme, T diet where the control diet contained DPC on corn replacement (25% DM basis), and T diet where the control diet contained DPC on corn replacement (25% DM basis) along with exogenous enzyme supplement.

This study aimed to evaluate the effect of adding herbal and aromatic plants at 1, 3, 5, 7% of total ratio DM supplementation of the incubation media of an in vitro rumen model.
Material And Methods: About 400±4 mg of feed sample (roughage and concentrate ratio of 45:55%) with each level, weighted into 125 mL glass bottles (6 bottles for each treatment), rumen fluid injected into these bottles and incubated at 39°C, after 24 h incubation digestibility of dry matter (IVDMD) and organic matter digestibility (IVOMD), total gas production (TG) and metabolic energy (ME) were studied.
