Identification of selection signatures in Capra hircus and Capra aegagrus in Iran
In this study, two populations of domestic and wild goats from Iran were analyzed to identify selection signatures. RSB, iHS, and XP-EHH statistics were used in order to identify robust selection signatures in the goat genome. Genotype data of domestic and wild goats from the NextGen project was used. The data was related to 18Capra aegagrus (wild goat) and 20Capra hircus (domestic goat) from Iran. The iHS method indicated 675 and 441 selection signatures inC. aegagrus andC. hircus, respectively. RSB and XP-EHH methods showed about 370 and 447 selection signatures inC. aegagrus andC. hircus, respectively. These selection s...

Outstanding Gir oocyte donors: How does individual factor affect in vitro embryo production efficiency?
AbstractThe oocyte donor plays a pivotal role in bovine in vitro embryo production (IVP) success. The individual factor affects blastocyst/oocyte ratio and determine the existence of outstanding performing animals. The aim of this study was to assess the extent of individual factor effect to IVP efficiency, in a population of Gir oocyte donors. Extreme (high or low IVP efficiency based on blastocyst/oocyte ratio) animals were selected out of a population of 250 oocyte donors (1,734 observations) to form high (>0.48,n = 40), average (0.17–0.48,n = 168), and low (<0.17,n = 42) efficiency donor groups. Cumulu...

Effects of low ‐protein diet and feed restriction on mRNA expression of cationic amino acid transporters in porcine skeletal muscles
AbstractWe investigated the effects of a low-protein diet and feed restriction on the mRNA expression of cationic amino acid transporters (CATs) in thelongissimus dorsi (LD),rhomboideus (RH), andbiceps femoris (BF) muscles of pigs. Eighteen piglets were divided into three groups: a control (CP21%), low-protein diet (LP, CP16%), and feed-restricted diet (FR, CP21%, 76% feed intake of control pigs) groups. The expression levels of CAT-1 in the LD and BF muscles of LP pigs were higher than that of control pigs, whereas that of FR pigs showed no difference. The CAT-2A expression levels in the RH muscle of FR pigs were higher t...

Exogenous spermidine effectively improves the quality of cryopreserved boar sperm
AbstractBoar sperm are less resistant to the dramatic environmental changes that occur during in vitro preservation. Spermidine has various physiological functions including the anti-oxidative effect. The main objective of this study was to clarify whether spermidine could protect boar sperm from the attack of reactive oxygen species under cryopreservation treatment. We set the concentrations of spermidine at 0, 2, 4, 6, and 8 mmol/L and evaluated the effects of spermidine on sperm motility, viability, malformation rates, kinetic parameters, membrane integrity, mitochondrial activity, DNA integrity, H2O2 content, malondi...

The short ‐term feeding of low‐ and high‐histidine diets prior to market affects the muscle carnosine and anserine contents and meat quality of broilers
AbstractFunctional dipeptides carnosine and anserine are abundant in muscle. We determined the effect of short-term dietary histidine (His) content on muscle carnosine and anserine contents and meat quality of broilers. Three groups of 28-day-old female broilers were fed diets with His contents of 67%, 100%, or 150% of requirement for 10 days before market (His contents 0.21%, 0.32%, and 0.48%, respectively). The carnosine and anserine contents of 0-h aged muscle significantly increased with dietary His content; in particular, the carnosine content was 162% higher in the His 0.48% group than in the His 0.32% group. The c...

Nutritional quality and organic acid profile of rice bran fermented with lactic acid bacteria isolated from horse feces
AbstractThe study aimed to determine the effect ofLimosilactobacillus equigenerosi andLigilactobacillus equi as inoculants for solid-state fermentation (SSF) in the proximate composition of nutrients and organic acid profile of rice bran (RB). The RB was treated with distilled water (DW) without inoculant (control),L. equigenerosi (T1),L. equi (T2), andL. equigenerosi andL. equi 1:1 (v:v) (T3). For the treatments, 90 mL of culture was pelleted and suspended with DW. Each treatment was replicated three times and incubated for 4, 7, and 10 days at 37°C. The crude protein, ether extract, crude ash, crude fiber, n...

Nicotinamide supplementation alters plasma lipidomic profiles of peripartal dairy cows
AbstractFatty liver syndrome, a common health problem in dairy cows, occurs during the transition from pregnancy to lactation. If the energy supplied to the cow's body cannot meet its needs, a negative energy balance ensues, and the direct response is fat mobilization. Nicotinamide (NAM) has been reported to reduce the nonesterified fatty acid concentration of postpartum plasma. To study the biochemical adaptations underlying this physiologic dysregulation, 12 dairy cows were sequentially assigned to a NAM (45 g/day) treatment or control group. Blood samples were collected on day (D) 1 and D21 relative to parturition. C...

A newly developed bacteriocin like substance to replace monensin in diets of lactating ewes
AbstractThe aim of the present experiment was to evaluate the effect of feeding a newly produced bacteriocin-like substance (BLS) as a replacement for monensin in the diets of lactating ewes. In Experiment 1, the effects of BLS or monensin at 0.5, 1, 1.5, and 2 g/kg diet on in vitro ruminal fermentation were compared. In Experiment 2, 30 multiparous Barki ewes were divided into three treatments in a complete randomized design for 90 days. The ewes were fed a basal diet without supplementation or supplemented with monensin or BLS at 0.5 g/kg DM diet. In Experiment 1, the highest levels of BLS and monensin decreased ga...
