Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, Volume 199, Issue 1, Page e21-e29, 4/11 July 2026.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

Impacts of Intercropping Maize–Grass–Legume for Silage Production and Oversowing Black Oat for Lamb Grazing on Soil Fertility

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Intercropping grasses and legumes could be an important strategy for sustainable food production in tropical weathered soils. This study aimed to assess the impact of intercropping systems comprising maize and grass with or without a legume for silage production and overseeded black oat overseeded for lamb grazing on crop production, root ...

Supplementation of Hermetia Illucens Larvae to Improve Growth Performance, Meat Quality, and Intestinal Microbiology of Broiler in a Cost‐Effective Manner

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Hermetia illucens larvae meal (HIL) improved broiler growth, carcass yield, gut microbiology, and profitability, with the highest performance observed at 12% inclusion. However, lower inclusion levels (4%) offered a better balance by enhancing meat quality and maintaining favourable fatty acid profiles while still supporting productive and economic ...

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.
