Effects of hyaluronic acid on sperm parameters, mitochondrial function  and apoptosis of spermatozoa in Simmental bulls with good and poor freezing ability
AbstractBulls with varying freezability exhibit substantial variation in semen characteristics after cryopreservation. Sperm freezability is positively correlated with membrane cholesterol content, membrane integrity, mitochondrial activity  and antioxidant content. The purpose of this study was to determine the optimal concentration of hyaluronic acid (HA) in bull sperm with different cryotolerances. Simmental bulls (n = 10) semen samples were taken and categorized based on their progressive motility (PM) after freeze-thawing: Group I, consisting of bulls (n = 5) with progressive sperm motility ≥45%, was consid...

High ‐fibre diets regulate antioxidative capacity and promote intestinal health by regulating bacterial microbiota in growing pigs
AbstractThis experiment was conducted to investigate the effects of a high-fibre diet on growth performance, nutrients digestibility, intestinal health, and intestinal microbiota composition of growing pigs. Twelve healthy “Duroc × Landrace × Yorkshire” castrates (49 ± 1.35 kg) were randomly divided into two groups with six replicates and one pig per replicate. The two diet treatments were fed the basal diet (CON) based on corn and soybean meal and high fibre diet (HF) respectively. The nutrition al levels of the two treatments were the same. The experiment lasted 28 days. The results showed that the ...

Toward making a high ‐quality silage from common reed (Phragmites australis)
AbstractThe effects of the addition of molasses (5 and 10% of dry matter: DM basis; M5 and M10 respectively) with or without urea (2%; U2, U2  + M5 and U2 + M10) on chemical and mineral composition, silage quality, microbial populations, buffering capacity and fermentation/digestion characteristics of common reed (Phragmites australis) ensiled under anaerobic conditions were investigated. The additives changed the silage quality of common reed compared with the control. Crude protein content was significantly (p< 0.0001) increased in urea-containing silages, whereas ash-free neutral detergent fibre concentration...

Dietary sulfated polysaccharides extracted from Caulerpa sp. and Padina sp. modulated physiological performance, antibacterial activity  and ammonia challenge test in juvenile rainbow trout (Oncorhynchus mykiss)
AbstractNowadays, the use of seaweed derivatives in aquaculture has drawn attention for their potential as an immunostimulant and growth promotor. The sulfated polysaccharide extracted (SPE) from green (Caulerpa sp.; SPC) and brown (Padina sp.; SPP) seaweeds with two concentrations (0.05% and 0.1%); nominated in four groups: SPC0.05, SPC0.1, SPP0.05, SPP0.1 and control group (free of SPE) were used for juvenile rainbow trout (Oncorhynchus mykiss) diet. Fish (N: 150; 8.5  ± 0.2 g) were selected aleatory distributed in 15 circular tanks (triplicate for the group) and fed test diets for 56 days. The outcomes revealed t...

Rumen ‐protected l‐carnitine supplementation during mating period altered metabolic status and reproductive performance of ewes
AbstractCurrent study hypothesized that dietaryl-carnitine (LC) inclusion during the mating period ameliorates both metabolic status and reproductive performance of ewes. Seventy Baluchi ewes (52  ± 4.2 kg of bodyweight and 18 ± 6 months old of age) were enrolled in this study. Animals were randomly allocated into two dietary treatments, control (only basal diet) or basal diet plus supplementation with a rumen-protected LC (Carneon 20 Rumin-pro; 20% LC; Kaesler Nutrition GmbH) at the rate of 10 g/head/day from 21 days before until 35 days after introducing rams to the ewes (MP). Feed intake was monitored by s...

Identification of sheep eimerian parasites, Eimeria crandallis and Eimeria faurei, employing microscopic and molecular tools
AbstractCoccidiosis, caused by apicomplexanEimeria species, is a protozoan disease that affects various species of wild and domestic animals. However, data available onEimeria diversity in ruminants in Saudi Arabia is meagre. Therefore, this study was designed to investigate some eimerian parasites infecting sheep (Sawakni and Harrie breeds) using microscopy and molecular methods for the first time in Saudi Arabia. Twenty-four fecal samples were collected from sheep farms. Based on the floatation technique, eimerian oocysts were observed in 8 of the 24 (33.33%) fecal samples. The coccidian-positive samples were subjected t...

Lactational performance and nutrients digestibility response of dairy buffaloes fed diets supplemented with probiotic (Streptococcus spp.) and fibrolytic enzymes
In conclusion, this study suggests that supplementing lactating buffaloes' diets with probiotic alone or in combination with fibrolytic enzymes would improve their productive performance without adversely impa cting their health. (Source: Journal of Animal Physiology and Animal Nutrition)
