Identification of a novel SNP in BMP15 gene and its association with litter size in Damani goats
This study examines the BMP15 (Bone Morphogenetic Protein 15) gene as a potential genetic marker for reproductive traits, specifically litter size, in Damani goats. Genomic DNA was extracted from 180 Damani goats, and a novel single-nucleotide polymorphism (SNP), g.557 G > A, was identified in the…

Can nano-liquid formulation of Andrographis paniculata and Moringa oleifera extract serve as an alternative to antibiotics for improving broiler performance and gut microbiota modulation?
Rising restrictions on antibiotic growth promoters require alternatives. Phytobiotics such as Andrographis paniculata and Moringa oleifera have shown potential, though their efficacy is often constrained by the instability of bioactive compounds during digestion and a limited understanding of their…

Effects of different water-soluble nitrogen in diets on in vitro digestibility and gas production
This study investigated the effects of replacing elephant grass (EG) with corn silage (CS) on in vitro rumen fermentation, digestibility, and greenhouse gas emissions. Five diets with 0–100% CS substitution (DM basis) provided water-soluble nitrogen (WSN) levels of 18.5–34.6% of total N. Substrates…

Effects of feeding different alfalfa hay on carcass characteristics, meat quality, and fatty acid profile of growing lambs fed complete pelleted diets
Herein, 40 growing male lambs of the Al-Naimi breed were randomly divided into 4 groups and fed a single diet with four particle sizes and lengths of alfalfa forage (1, 5, 10, or 15 mm) in a pelleted complete diet (PCD); lambs were housed individually for 14 weeks. Compared with lambs in the…

Efficacy of Ashwagandha root extract on cognition parameters in geriatric dogs: a randomized, double-blind, placebo-controlled trial
Cognitive deficits increases as dogs grow. Ashwagandha is a known adaptogen with antioxidant and anti-inflammatory actions, thus promoting health in geriatric pets. This study was conducted to assess whether Ashwagandha root extract (ARE) has a role as a nervine tonic in geriatric dogs with an…

Effects of continuous grazing in saline islet areas rich in wild halophytes on digestibility, liver function and lambs' growth and carcass performance
The effects of continuous grazing on an islet dominated by halophytic flora on digestibility, feed intake, growth, health indicators and carcass traits of Barbarine × Queue Fine de l'Ouest lambs were studied. Ewe lambs (23.80 ± 2.14 kg) were divided into two groups. The first one was reared on…

Comparative effects of clove bud powder (Syzygium aromaticum) and sodium bicarbonate on anaesthetic induction and recovery in juvenile three-spotted tilapia (Oreochromis andersonii, Castelnau 1861)
Access to affordable and effective anaesthetic agents is crucial for the welfare of cultured fish, particularly in resource-limited settings. This study evaluated clove bud powder (Syzygium aromaticum) and sodium bicarbonate as cost-effective anaesthetics for juvenile Oreochromis andersonii, a…

Effects of contaminated bedding materials on its microbial load and on broiler chickens performance, foot health and meat quality
Bedding material is an important component of the broiler rearing environment and can influence litter moisture and microbial conditions during production. Changes in these environmental conditions may subsequently affect overall performance and meat quality. This study evaluated the effects of…

Fertility duration in indigenous hens following controlled mating, and growth performance of their offspring
In Uganda, indigenous chickens constitute 70% of the poultry population, but their reproductive efficiency is affected by insufficient fertility data. This study evaluated the fertility duration in indigenous hens after mating and compared the growth performance of their offspring with that of…

Rumen microbial diversity and functional annotation in cattle fed yeast supplements using shotgun metagenomics
This study evaluated the effect of yeast supplementation on rumen microbial diversity and fermentation potential in cattle. Four rumen-fistulated cattle were assigned to four treatments: T0(control), T1(150 mL LEBAS®/kg feed), T2(300 mL LEBAS®/kg feed) and T3(12 g lyophilized yeast/day) across four…

Phenotypic characterization of indigenous chickens reared under an extensive production system in Namibia
This study characterized indigenous chickens reared in the four selected Northern regions of Namibia, namely Omusati, Oshana, Ohangwena and Kavango East. A total of 233 indigenous chickens were investigated for plumage colour and type, comb types, shank colour and body weight. Plumage colour, shank…
