Interactive effects of dietary supplementation between illite and probiotic on productive performance, intestinal microflora, and blood profiles of laying hens
This study investigates the interactive effects of dietary illite and probiotic on productive performance, intestinal microflora, and blood profiles of laying hens. A total of 432 laying hens at 24 weeks old were allotted into six dietary groups. An experimental design was composed with a 3 (illite levels: 0, 0.3, and 0.6%)  × 2 (probiotic levels: 0 and 0.2%). The probiotic based onBacillus subtilis,Saccharomyces cerevisiae, andB. licheniformis was used. There were interactions between illite and probiotic on total microbes andsalmonella of digesta. Higher egg production was observed in hens fed a diet supplemented wi...

Diversity of mitochondrial D ‐loop haplotypes from ancient Thracian horses in Bulgaria
AbstractThe domestication of the horse began possibly more than 5000  years ago in the western part of the Eurasian steppe, and according to the leading hypothesis, horses first spread from the Steppe toward the region of the Thracian culture, starting in the second half of the 2nd millennium BCE and flourished from the fifth to first centuries BCE, mainly located in present-day Bulgaria. We analyzed 17 horse bone remains excavated from Thracian archaeological sites (fourth to first centuries BCE) in Bulgaria and successfully identified 17 sequences representing 14 different haplotypes of the mitochondrial D-loop. Compar...

Differences in ingestive behavior between grazing goats and sheep at the bite scale
This study aimed to clarify the differences in ingestive behavior between goats and sheep at the bite scale. Animals were allowed to graze a feeding station of bahiagrass (Paspalum notatum Fl ügge) with two sward heights (short and tall) to two levels of bite depletion (20 and 40 bites). Ingestive behavior variables, which represent the rate and mass of bites and chews, intake rate, bite dimensions, and bite placement characteristics, were quantified. The interspecies difference in inge stive behavior became obvious at the short sward. Goats reduced the inter-bite distance and maintained bite overlapping but took deeper b...

Bayesian analysis of genetic and environmental effects on litter traits in a red fox (Vulpes vulpes) herd under long ‐term selection
The objectives of this study are to determine the effects of individual and maternal inbreeding, birth year, and dam and sire age on litter size at birth (LSB) and at weaning (LSW) and on preweaning mortality (PWM) in a red fox herd under long-term selection, and to determine the heritability of these traits. In total, 37,973 pedigreed individuals were used to calculate the inbreeding coefficients, based on records of 14,527 litters of 3856 dams born from the year 1958 to 2015. Two data sets (all data and data for the Polish variety) were analyzed. The highest heritability was estimated for PWM (0.292, 0.306) and the lowes...

Effect of different odors on the fighting behavior of weaning piglets after merging into a large pen
AbstractIn intensive pig production, the fighting behavior of weaning piglets after merging pens is relatively common. Fighting behavior not only easily causes injury in pigs but also affects the production performance of pigs. To reduce fighting behavior in farms, this study aimed to explore the possible effect of odorous substances on piglet fighting behavior after merging into a large pen. Six different sprays were tested: original creamy, cheese flavor, orange flavor, truffle, vanilla and pigpen flavor. In each experiment, two groups were set (one odor-sprayed and no sprayed control), and 12 pigs were used per group. A...

Estimation of genetic parameters for production, reproduction, and growth curve of Fars indigenous chicken
AbstractIranian native chicken, including Fars indigenous chicken, is an important genetic resource due to its adaptation to stressful environmental conditions, good endurance and resistance to disease. The aim of this research was to determine the genetic infrastructure of Fars indigenous chicken using several nonlinear functions. The dataset included body weight at hatch (BW1), body weight at the 8th week (BW8), body weight at the 12th week (BW12), weight at sexual maturity (WSM), age at sexual maturity (ASM), number of eggs in the first 12  weeks of laying period (EN), egg weight at the first day of laying (EW1), aver...

Reduction of oocyte shedding and cecal inflammation by 5 ‐aminolevulinic acid daily supplementation in laying hens infected with Eimeria tenella
AbstractThe present study aimed to evaluate the effects of 5-aminolevulinic acid (5-ALA) onEimeria tenella infection in laying hens. Oocyst shedding and histopathology were evaluated. A reduced oocyst shedding was observed 5 and 7  days post-infection (dpi) in the 5-ALA-administered group, but the total number of oocysts during the first infection period was not different between control and 5-ALA-treated groups. AfterE.  tenella attack infection, the period of oocyst shedding in the 5-ALA-administered group lasted less long than that in controls. During the attack infection period, the total number of fecal oocysts in ...

Vascular endothelial growth factor isoforms are expressed in the uterus during estrous cycle of golden hamsters (Mesocricetus auratus)
AbstractWe investigated VEGF expression in the uterus during the estrous cycle in the golden hamster (Mesocricetus auratus). Reverse transcription polymerase chain reaction of genes expressed in the uterus revealed the presence of at least three different VEGF isoforms (hamster VEGF188, VEGF164, and VEGF120). They were highly homologous to the respective mouse and human isoforms. Furthermore, VEGF164 and VEGF120 were predominantly expressed in the hamster uterus during the estrous cycle. In situ hybridization revealed that VEGF is expressed only in the luminal and glandular epithelium of the endometrium but not in the stro...
