Potential to Improve Nitrogen Fertilizer Use Efficiency and Mitigate Pollution in Tropical Pastures Grazed by Sheep

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
We hypothesize that increasing N application rates will affect N use efficiency (NUE) for lambs grazing warm‐season annual grasses. We evaluated the effect of N fertilizer application rates (50, 100, 200, and 400 kg N/ha) on forage pearl millet (Pennisetum glaucum (L.) R.) and animal responses: N balance and NUE per animal and per area basis.

Temperature and duration of heating of sunflower oil affect ruminal biohydrogenation of linoleic acid in vitro [PDF]

, 2010
Sunflower oil heated at 110 or 150°C for 1, 3, or 6 h was incubated with ruminal content in order to investigate the effects of temperature and duration of heating of oil on the ruminal biohydrogenation of linoleic acid in vitro.

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

Effects of feeding almond hulls to light lambs on carcass characteristics and meat quality

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3876-3884, April 2026.
Abstract BACKGROUND Almond hulls (AH) are the main by‐product of almond processing for human consumption and contain bioactive compounds that can improve meat quality. Although AH are used as feed for dairy cows in some countries, information on their potential effects on meat quality is limited.

Repeated Ruminal Acidosis Challenges in Lactating Dairy Cows at High and Low Risk for Developing Acidosis: Ruminal pH [PDF]

Journal of Dairy Science, 2008
The primary objective of this experiment was to determine whether lactating dairy cows that are at high (HR) or low (LR) risk for experiencing ruminal acidosis, because of their diet and stage of lactation, differ in their response to an acidosis challenge.

Evaluation of cardiac injury biomarkers in sheep with acute lactic acidosis [PDF]

Āsīb/shināsī-i Darmāngāhī-i Dāmpizishkī, 2016
Rumen lactic acidosis is a metabolic disorder which develops in ruminants that have ingested large amounts of unaccustomed feeds rich in ruminally fermentable carbohydrates.

Effect of Diet Neutral Detergent Fibre Content on Dry Matter Intake, Nutrient Digestibility, Growth Efficiency and Carcass Characteristics of Finishing South African Mutton Merino Wether Lambs

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Feeding South African Mutton Merino lambs low‐NDF lucerne hay diets improved nutrient digestibility, energy utilisation, growth efficiency, and carcass quality. Despite lower intake at the lowest NDF level, fibre digestibility and feed conversion improved, indicating that highly digestible, low‐NDF finishing diets enhance lamb growth and carcass traits.

Effects of oregano essential oil on the ruminal pH and microbial population of sheep.

PLoS ONE, 2019
Oregano essential oil (OEO), which has antimicrobial properties, may be used for altering the ruminal pH and microbial populations of sheep, as observed by the altered volatile fatty acid patterns.

Comparative assessment of probiotics and monensin in the prophylaxis of acute ruminal lactic acidosis in sheep

BMC Veterinary Research, 2018
Background Acute ruminal lactic acidosis (ARLA) is a major nutritional and metabolic disorder usually characterized by excessive or non-adapted intake of diets rich in nonstructural carbohydrates. Feed additives that regulate the ruminal environment have

Effects of replacing different proportions of barley grain by barley fibre on performance of dairy bulls [PDF]

, 2007
The objective of the present experiment was to study the effects of partial replacement of barley grain with barley fibre (BF) on animal performance, carcass traits and diet digestibility of growing dairy bulls.
