Objective: Stripe marks, which occasionally occur on the shell, do not cause breakage to the shell and shell membranes of eggs. This study investigated the quality of intact eggs (IEs), minor stripe-marked eggs (MEs), severe stripe-marked eggs (SEs), and cracked eggs (CEs) during 3-week storage at 25°C. Methods: Shell eggs were collected the day after being laid and were washed. Among them, eggs without any visual cracks or stripe marks on the shells were evaluated as intact eggs by the plant employees using candling in a darkened egg storage room; the remaining eggs exhibited some eggshell defects...

The study was conducted to evaluate the effects of different methionine (Met) sources on production performance, reproduction performance, egg quality and serum biochemical indices in broiler breeders. After receiving a basal diet (containing 0.25% Met) for a 2-wk pretreatment period, a total of 360 39-wk-old Lingnan yellow broiler breeders were randomly allocated to four treatments with six replicates each (15 birds per replicate). Breeders were fed with basal diets (control) or diets supplemented with DL-methionine (DLM), DL-2-hydroxy-4-methylthio butytric calcium (MHA-Ca) and coated DL-Met (CME) respectively (containing 0...

Objective: The early growth response (Egr) family consists of four members (Egr1, Egr2, Egr3, and Egr4) that are zinc finger transcription factors. Among them, Egr3 is involved in transcriptional regulation of target genes during muscle spindle formation and neurite outgrowth. We previously showed that the immunoreactive Egr3 is localized on oocyte spindle and accumulate near the microtubule organizing center (MTOC) during meiosis I in mice. Egr3 was also shown to be localized on spermatocytes...

The study was conducted to determine the effects of grazing management (tethering vs herding) and floor type (earth vs slatted) on the concentrations of blood metabolites, activity of creatine kinase, body weight (BW), body condition score (BCS) and carcass characteristics of castrated Nguni goats. Forty eight, 7 month old goats were randomly allocated to herding (H) and tethering (T) treatments and accommodated in pens with slatted (SF) and earth (EF) floors. The T and H treatments were imposed daily, for 5 months, between 0800- 1300 hours followed by penning...

Melanocortin receptor 1 (MC1R) and Agouti signaling protein (ASIP) are two widely reported pivotal genes that significantly affect the regulation of coat colour. Qingyu pig, a Chinese indigenous pig breed, exhibits two types of coat colour phenotypes, including pure black and white with black spotting respectively. The objectives of this study were to investigate whether the polymorphisms of these two genes are associated with coat colour and analyze the molecular mechanism of the coat colour separation in Qingyu pig...

Objective: To create genetically modified goat as a biopharming source of recombinant human lacotoferrin (hLF) with TALEN. Methods: TALENs and targeting vector were transferred into cultured fibroblasts to insert hLF cDNA in the goat beta-lactoglobulin (BLG) locus with homology-directed repair (HDR). The gene targeted efficiency was checked using sequencing and TE7I assay. The bi-allelic gene targeted colonies were isolated and conformed with PCR, and used as donor cells for somatic cell nuclear transfer (SCNT)...

The objective of the study was to determine the effects of increasing levels of metabolizable protein (MP) on lactation performance and nitrogen (N) efficiencies in lactating dairy cows. Nine multiparous cows in mid lactation [113±25 days in milk (DIM)] received three treatments in a 3×3 Latin square design with a period length of 21 days. The treatments were three diets, designed to provide similar energy and increasing supply of MP (g/d)-2371 (low), 2561 (medium), and 2711 (high) with corresponding crude protein (CP) levels (%)-15...

The use of locally produced forage (LPF) in cattle production has economic and environmental advantages over imported forage. The objective of this study was to characterize the nutritional value of LPF commonly used in Korea. Differences in ruminal fermentation characteristics were also examined for the LPF species commonly produced from two major production regions: Chungcheong and Jeolla. Ten LPF (five from each of the two regions) and six of the most widely used imported forages originating from North America were obtained at least three times throughout a year...

Objective: This study was conducted to characterize the behaviors and the body weight of suckling piglets in different social environments. Methods: Two groups of sows and suckling piglets housed either in individual farrowing crates in separate pens (1.8 m × 2.4 m, the control group) or in groups of three sows with their piglets in farrowing crates in a large common enclosure (5.4 × 2.2 m, the treatment group) were observed with the aid of video technology for 9 consecutive hours on days 1, 2, and 3, after mixing...

Objective: The objective of the present study was to investigate the effects of farrowing month (FM), parity and sex on the growth performance of Berkshire swine raised in alternative production systems. Methods: A total of 40 farrowing records from 27 sows and 1258 BW records from 274 piglets collected over a two-year period were used for the analysis. Body weights were recorded at birth, weaning (28 d), 56, 84, 112 and 140 days. Any BW not recorded on schedule was recalculated to conform the days of age among corresponding BW records, using growth curves drawn with polynomial functions whose power was determined by the number of existing observations for each individual...

The aim was to evaluate carcass characteristics, cut yield, and meat quality in lambs that were fed different inclusion levels of palm kernel cake. Forty-five woolless castrated male Santa Inês crossbred sheep with an initial average body weight of 23.16 ± 0.35 kg were used. The experimental design was a completely randomized design with five treatments, with palm kernel cake in the proportions of 0.0, 7.5, 15.0, 22.5, and 30.0% with nine replications per treatment. The empty body weight, carcass weight and yield, and fat thickness decreased linearly (P<0...

Hypocalcemia is an important metabolic disease of dairy cows during the transition period, although the effect of hypocalcemia on biological function in dairy cows remains unknown. In this study, proteomic, mass spectrum, bioinformatics and western blotting were employed to identify differentially expressed proteins related to serum Ca concentration. Serum samples from dairy cows were collected at three time points: 3rd days before calving (day -3), the day of calving (day 0), and 3rd days after calving (day +3)...

"Hatchability" is an important economic trait in domestic poultry. Studies on poultry hatchability focus mainly on the genetic background, egg quality, and incubation conditions, whereas the molecular mechanisms behind the phenomenon that some ducklings failed to break their eggshells are poorly understood. In this study, the transcriptional differences between the livers of normally hatched and assisted ducklings were systematically analyzed. The results showed that the clean reads were de novo assembled into 161,804 and 159,083 unigenes (≥200-bp long) by using Trinity, with an average length of 1206 bp and 882 bp, respectively...

In this study, 562 pure Large white pigs were used to identify genomic regions controlling growth traits. Four growth traits were studied: average daily gain from 30 KG to 100 KG or 115 KG and days to 100 KG or 115 KG, using a panel of 54,148 SNPs. We detected 6 significant and 12 suggestive SNPs and further identified 9 candidate gens closed to significant or suggestive SNPs, which including SOGA1, RSPO2, MAP2K6, PLCB1, ARHGAP24, CPEB4, GLI2, NYAP2, and ZFPM2. Gene ontology analysis and literature mining indicated that these candidate genes are involved in bone, muscle, fat, and lung development, which is either directly or indirectly related to growth traits...

Objective: The purpose of this study was to investigate the influence of AMP-activated protein kinase (AMPK) activation on protein acetylation and glycolysis in postmortem muscle to better understand the mechanism by which AMPK regulates postmortem glycolysis and meat quality. Methods: A total of 32 mice were randomly assigned to four groups and intraperitoneally injected with 5-Aminoimidazole-4-carboxamide1-β-D-ribofuranoside (AICAR, a specific activator of AMPK), AICAR and histone acetyltransferase inhibitor II, or AICAR, Trichostatin A (TSA, an inhibitor of histone deacetylase I and II) and Nicotinamide (NAM, an inhibitor of the Sirt family deacetylases)...
