Individual and Combined Effect of Zinc-L-Selenomethionine Complex with Mannan-Oligosaccharide on Growth Performance, Carcass Characteristics, Gut Development and Immune Response in Broilers.

Due to the increased restrictions on antibiotic growth promoters (AGPs), natural substitutes such as organic selenium and prebiotics are gaining increased attention to enhance the gut health and performance of broilers. This study aimed at assessing the effects of organic selenium separately and in combination with mannan-oligosaccharides (MOSs) on gut development, immunity, carcass traits and overall growth performance in broiler chickens. For this study, 528-day-old straight-run broiler chicks (Ross-308) were assigned to four dietary treatments (six replicates of 22 birds each), in a completely randomized design under a 2 × 2 factorial layout, including: (1) Se0.

Effects of water and feed based RISCO-NUTRIFOUR probiotic supplementation on the technological and physicochemical quality of broiler breast meat.

Introduction: Consumer interest in poultry and high-quality meat products has increased. Probiotics are used in the diet to improve the quality of broiler meat. The aim of this study was to investigate the effects of multi-strain probiotics (RISCO-NUTRIFOUR®, RNF) on the quality and physicochemical properties of broiler meat.

Lasalocid-supplemented diets for improving carcass characteristics, meat quality, and fatty acids content of goats.

This study investigated the effects of lasalocid supplementation on the diet of goats to improve carcass characteristics, meat quality traits, and fatty acid content. Sixty intact male Ardhi goats were used. The kids were divided into four treatment groups, each with 15 animals, and further subdivided into five subgroups, each with three goats, in a completely randomized design.

Exploring the Role of Salt Supplementation on Milk Composition, Fatty Acids, and Insulin Response in Lactating Camels.

Camel milk is a valuable food source with unique nutritional properties and potential health benefits. This study investigated the influence of high dietary salt on milk composition and fatty acid (FA) profile as well as insulin regulation in dairy camels. Twelve multiparous female camels were used in a crossover design with two treatments: control concentrate (CON; 1.

Assessment of gastrointestinal nematode infections in dairy cattle and the associated risk factors in Northern China.

Importance: Gastrointestinal nematodiasis poses significant economic losses in the livestock industry due to mortality, morbidity, and decreased production.

Objective: This study examined the prevalence of gastrointestinal nematodiasis in dairy cattle in Central Inner Mongolia, Northern China, the associated risk factors, and the effects on the pepsinogen and gastrin levels.

Methods: Fecal samples (n = 590) were collected from four regions and analyzed using the standard floatation and sedimentation techniques.

Foot-and-mouth disease seroprevalence is higher in young female crossbred sheep and goats compared to their counterparts in the border area between Pakistan and Afghanistan.

Objective: Foot-and-mouth disease (FMD) is a highly contagious disease in ruminants that causes significant economic losses worldwide. However, the prevalence of FMD virus (FMDV) in small ruminants has been overlooked in Pakistan. This study aimed to determine the prevalence of FMD in sheep and goats in the border area between Pakistan and Afghanistan.

Postpartum Body Condition Score (BCS) and Lactation Stage (30 and 60 Days) Affecting Essential Fatty Acids (EFA) and Milk Quality of Najdi Sheep.

Body condition scoring (BCS) can be used to assess the energy reserves of sheep during feeding, production, and weaning. The aim of this study was to evaluate the influence of BCS after parturition in stages of lactation (30 and 60 days) on the milk quality of Najdi ewes. The ewes were milked in the morning after their lambs had been isolated.

Identification of Genetic Polymorphisms of PI, PIII, and Exon 53 in the Acetyl-CoA Carboxylase-α (ACACα) Gene and Their Association with Milk Composition Traits of Najdi Sheep.

Recently, increasing attention has been paid to sheep milk products, which are high in saturated fatty acids (SFA), and the extent of their impact on human health. This study aimed to identify SNPs for PI, PIII, and Exon 53 in the gene and their association with the MC and FA profiles in Najdi sheep milk. A total of 76 multiparous Najdi ewes were used, and they were maintained using the same feeding system.

Heavy Metals Levels in Soil, Water and Feed and Relation to Slaughtered Camels' Tissues () from Five Districts in Saudi Arabia during Spring.

Soil, water, and forage contaminated with toxic heavy metals such as Pb, Cd, and Co can affect the meat and liver quality of camels raised in this area which affect human health. This study aimed to determine the concentrations of Pb, Cd and Co in soil, water, feed and young camels' carcass tissues (meat, liver, whole blood, rumen fluid and rumen tissue) from five districts in Saudi Arabia during the spring. All samples were wet-digested and analyzed by ICP-OES for heavy metals.

Regional and Seasonal Variability of Mineral Patterns in Some Organs of Slaughtered One-Humped Camels [] from Saudi Arabia.

Camel products are receiving great interest worldwide because of their high functional properties and nutritive values. Therefore, this study was focused on the variation of copper [Cu], zinc [Zn], manganese [Mn], selenium [Se], iron [Fe], iodine [I], and some heavy metals, cobalt [Co], lead [Pb], and cadmium [Cd], in the blood and tissues of slaughtered camels from five regions in Saudi Arabia [SA] during the summer and winter seasons, because environmental factors vary from region to region. Whole blood, meat, liver, rumen fluid, and rumen tissues were collected from the slaughterhouse in each region during the two seasons.

Effects of Roughage Quality and Particle Size on Rumen Parameters and Fatty Acid Profiles of Longissimus Dorsi Fat of Lambs Fed Complete Feed.

The fatty acid composition for the longissimus dorsi (LD) fat of carcass sheep is a crucial factor impacting meat quality. We performed a 90-day feeding trial of 25 Naemi lambs to investigate the effects of roughage sources (alfalfa or wheat straw) of two sizes (regular and 1 cm chopped) when fed with pelleted total mixed ration (TMR) on the growth performance, fermentation patterns, and fatty acid (FA) composition of longissimus dorsi (LD) fat. Lambs were randomly assigned to individual pens with five treatment diets, as follows: C, control group with TMR; T1, TMR and regular alfalfa hay; T2, TMR and alfalfa hay chopped to 1 cm; T3, TMR and regular wheat straw; and T4, TMR and wheat straw chopped to 1 cm.
