The demand of optimal protein for human consumption is growing. Food and Agriculture Organization (FAO) has highlighted aquaculture as one the most promising alternatives this supply gap due to high efficiency fish growth. However, been facing its own sustainability problem, because traditionally satisfied with use fishmeal (FM) main source. Some sustainable substitutes FM come from insects. present manuscript provides insight into an experiment carried out on rainbow trout (Oncorhynchus...
The aquaculture industry is diminishing the amount of fishmeal needed to maintain its protein demand. Alternatives are tested in this way, being insects one most promising. In study, two different insectmeals were at replacement proportions (150 and 300 g·kg-1) diets for Oncorhynchus mykiss. This study covers diverse aspects related growth, utilization, physiological status fish, quality final product. inclusion had no negative effects on utilization fish. At highest level with Tenebrio...
A high intramuscular fat content characterizes Wagyu (WY) cattle breed. Our objective was to compare beef from WY, WY-by-Angus, or Wangus (WN) steers with European, Angus-by-Charolais-Limousine crossbred (ACL), considering metabolic biomarkers pre-slaughtering and nutritional characteristics, including health-related indexes of the lipid fraction. The fattening system olein-rich diets no exercise restriction included 82 steers, 24 29 WN, ACL. slaughter ages weights were (median interquartile...
Meat quality depends on tissue composition which is in turn influenced by different factors, such as diet, genotype, age, or sex. We evaluated the effects of breed, 24 h fasting, and dietary energy source (HO: oleic acid versus CH: carbohydrates) expression candidate genes involved adipogenesis, lipogenesis, lipolysis adipose from Iberian Duroc growing pigs. The pigs showed greater feed intake, backfat thickness, saturated fatty acids (SFA) content subcutaneous fat, whereas had ham weight...
In this study, we analyzed the effects of breed, diet energy source, and their interaction on adipose tissue transcriptome in growing Iberian Duroc pigs. The study comprised 29 19 males, which were kept under identical management conditions except nutritional treatment. Two isoenergetic diets used with 6% high oleic sunflower oil (HO) or carbohydrates (CH) as sources. All animals slaughtered after 47 days treatment at an average live weight 51.2 kg. Twelve from each breed (six fed diet)...
There is an urgent need to identify the effects of temperature on production traits. This study aimed determine impact pig in three environments (T°Cgrowing-°Cfattening-°Cfinishing = T24-24-21, T19-19-19, and T23-17-15) growth curve parameters, body weight gain (DBWG), feed intake (DFI), efficiency during growing, fattening finishing stages, carcass yield primal cuts (ham, shoulder, loin) 158 Duroc × Iberian pigs. Maturation rate was higher T23-17-15 than T19-19-19 (P < 0.001). Pigs reached...
ABSTRACT The influence of estrus and double ovulations Holstein heifers on a 5d‐Co‐synch 72 h protocol during summer was explored. Cycling the 5d‐Co‐72 synchronisation were randomised to carry progesterone device (116) from day 0 5 or not (97), them 100 84 underwent fixed‐time artificial insemination (FTAI). Another 70 showed before first GnRH inseminated. Heifers pregnant 34% (33/97) without device, 44.0% (51/116) with 44.3% (31/70) inseminated after estrus. Pregnancy per (P/AI) tended be...
Abstract Background Taste receptor genes are expressed in sensory cells located the tongue and influence food preferences, voluntary feed intake, other relevant traits. perception may differ between livestock breeds that show differences eating behaviour animals receive different diets or phenotypic variation intake related-traits. The objectives of this work were to deepen understanding regulation function taste circumvallate papillae obese Iberian pigs comparison Duroc pigs, characterize...
The aim of the present study was to determine whether levels reactive oxygen species (ROS) substances production and lipid peroxidation sperm membrane were related quality that ejaculates exhibited after cryopreservation in boars. Ejaculates from 42 healthy boars used this they cryopreserved with lactose-egg yolk extender (LEY). Several parameters assessed by flow cytometry samples incubated for 30 150 min at 37 °C thawing: percentage intact plasma (SIPM), intracellular through mean DCF...
The conservation of genetic resources in pig breeds, notably the Iberian pig, is crucial for improvement and sustainable production. Prolonged storage liquid nitrogen (LN
The aim of the present study was to evaluate effect that addition cholesterol-loaded cyclodextrins (CLC) thawing extender has on quality frozen-thawed boar sperm. Pooled semen (n = 5) from three boars used for experiments. cryopreserved with an egg-yolk-based extender, it diluted after in Beltsville solution (BTS) supplemented different concentrations CLC (0, 12.5, 25, 50 or 100 mg/500 × 10(6) sperm), and these samples were incubated at 37°C 150 min. following parameters sperm evaluated 30...
CASA kinetic parameters are often evaluated in a diagnostic centre. How storage conditions affect ejaculates up to evaluation is unclear. We assessed, 25 commercial bulls electroejaculated the field, impact of time until (0–2 h, 4–6 and 24 h post-ejaculation), holding temperature (5 °C vs. room temperature), extender (AndroMed®, BIOXcell® or INRA96®) on parameters. Total progressive motility, VCL, VAP, ALH, BCF, STR, LIN, WOB were assessed. preserved for post-ejaculation, except AndroMed®....
microRNAs play pivotal roles during mammalian reproduction, including the cross-talk between gametes, embryos and maternal genital tract. Mating induces changes in expression of mRNA transcripts female, but whether miRNAs are involved remains to be elucidated. In current study, we mapped 181 porcine peri-ovulatory female reproductive tract: Cervix (Cvx), distal proximal uterus (Dist-Ut, Prox-Ut), Utero-tubal-junction (UTJ), isthmus (Isth), ampulla (Amp), infundibulum (Inf) when exposed semen...
The current European protein deficit is estimated as high 70% of present needs. Because the content their seeds, grain legumes are attractive candidates for lowering deficiency in plant production. objective this work was to identify new sources vegetable that would reduce our dependence soy, main source manufacture feedstuffs. To achieve goal, we determined proximate composition, bioactive components, well antinutritional factors studied seeds. In general, protein, fat and carbohydrates...
Seminal parameters can be evaluated in situ, or samples delivered to a diagnostic centre. How storage conditions affect ejaculates up evaluation is unclear. We assessed, 25 commercial bulls electroejaculated the field, impact of time until (0–2 h, 4–6 and 24 h post-ejaculation), holding temperature (5 °C vs. room temperature), extender (AndroMed®, BIOXcell® INRA96®) on semen quality. Acrosome integrity, sperm viability morphology, CASA-total progressive motility, pH, colony-forming units...
