The objectives of this research were to describe the feed sorting, feeding behavior, and feed intake of cows consuming a close-up ration and to determine if these behaviors are affected by competition for access to the feed bunk. Thirty-six dry Holstein cows, consuming a close-up total mixed ration diet, were assigned to 1 of 2 treatments: 1) noncompetitive (1 cow/feed bin) or 2) competitive (2 cows/feed bin). Dry matter intake, feeding behavior, and sorting behavior were monitored for each feed bin on 4 separate days during wk 2 and 3 before the anticipated calving dates of the cows. Fresh feed and orts were sampled daily from each bin and were subjected to particle size analysis. The particle size separator consisted of 3 screens (18, 9, and 1.18 mm) and a bottom pan resulting in 4 fractions (long, medium, short, and fine). Sorting was calculated as the actual intake of each particle size fraction expressed as a percentage of the predicted intake of that fraction. Regardless of treatment, the cows sorted against long particles and for short and fine particles. Competition at the feed bunk had no effect on the sorting behavior, dry matter intake, or feeding time of the cows, but did dramatically increase the feeding rate of the cows. The competitively fed cows also had fewer meals per day, and tended to have larger and longer meals. Our results suggest that increased competition at the feed bunk promotes feeding behavior patterns that will likely increase the between-cow variation in composition of total mixed ration consumed.

Introduction: Nowadays, complementary medicine such as aromatherapy has an important application in medicine, particularly in treating anxiety. The objective of the present study was to compare the effects of aromatherapy using lavender (Lavandula angustifolia Miller) and Citrus aurantium L. extracts on the anxiety level of patients undergoing laparoscopic cholecystectomy at Shiraz University of Medical Sciences Training Hospital in Iran. Methods: This Randomized Clinical Trial (RCT) was carried out in 2017 on a total of 90 patients undergoing laparoscopic cholecystectomy using aromatherapy. The subjects were randomly assigned to 3 groups based on the inclusion and exclusion criteria using sampling methods based on the goals. Two groups received either aromatherapy with Lavandula angustifolia Miller extract, aromatherapy with Citrus aurantium L. extract. The third group (control) received a placebo (odorless oil). The aromatherapy was performed on all subjects for 20 minutes. Patient anxiety was assessed using a Spielberg questionnaire before and after applying the aromatherapy intervention. The data obtained were analyzed by SPSS software via Chi-square test, one-tailed variance analysis, Tukey, t-tests, and Kruskal-Wallis test. Results: State and trait anxiety decreased for the aromatherapy groups, compared to control group, after applying the aromatherapy (P<0.001); moreover, there was an increased severity of anxiety in the control group (P<0.05). Indeed, the effects of aromatherapy with Lavandula angustifolia Miller and Citrus aurantium L. extracts were observed and confirmed; both extracts significantly decreased the severity of anxiety in the trial groups as compared to the control group (P<0.001). Moreover, the effect of aromatherapy with both of the aforementioned extracts was similar to each other. Conclusion: There was no significant difference between the lavender (Lavandula angustifolia Miller) and Citrus aurantium L. extracts in aromatherapy; therefore, either extract may be applied and useful in the clinic to alleviate preoperative anxiety.

Background: Gastroesophageal reflux disease (GERD) is one of the most common diseases in society, affecting up to 40% of the population. It has major impact on the quality of life and a high burden on medical expenditure. In this work, herbs used by ancient Iranians to treat GERD have been introduced. Methods: Different well-known Persian textbooks and recent electronic databases were searched to explore the treatment of GERD and the pharmacological mechanisms of the identified medicinal plants. Results: GERD has been known for many centuries, and many herbal remedies for its treatment have been elucidated in traditional medical literature. We found 25 medicinal herbs in Persian medicine books and searched for evidence to support them in the current literature. Conclusion: Although their active components or the mechanism of action were not known by the ancient Persians at that time, their persistent use during different centuries might indicate their effectiveness. Owing to their potential, medicinal herbs are a viable option for the treatment of diseases like GERD even today.

To evaluate the effects of supplementation of feed additives in the last trimester of pregnancy on placental characteristics and offspring performance, this study was conducted with 48 estrous-synchronized Ghezel ewes that had randomly been assigned to one of the following six groups (n = 8): ad libitum feeding (AL); feed restriction (RF; 60% of ad libitum intake); feed restriction + propylene glycol (PG); feed restriction + propylene glycol + monensin sodium (MS); feed restriction + propylene glycol + rumen-protected choline chloride (RPC); feed restriction + propylene glycol + monensin sodium + rumen-protected choline chloride (PMC). Birth weight, body size, and rectal temperature of lambs were determined within 24 h of birth. The presence of lambs at 87 days of age was used as an index of survival to weaning. The outcome of this study was that the average placental weight of ewes in the AL and MS groups was the highest and lowest, respectively, among the treatment groups (p < 0.01). RPC ewes presented higher placental efficiency compared to AL, RF, and MS ewes (p < 0.05). The largest and smallest crown-to-rump lengths (CRLs) were observed in PMC and RF lambs, respectively (p < 0.01). In addition, lambs born from PMC, RPC, and PG ewes had a longer curved crown-to-rump length (CCRL) than those born from AL and RF ewes (p < 0.01). The concurrent administration of propylene glycol and rumen-protected choline chloride resulted in the highest birth weight among treatment groups (p < 0.01). Lambs born to PMC and RPC ewes had a higher survival rate and rectal temperature than those born to RF ewes (p < 0.05). It can be concluded that although dietary restriction does not have adverse effects on lambs’ performance compared with ad libitum intake, the combined administration of propylene glycol and rumen-protected choline chloride in the ewes’ restricted diet can improve placental characteristics and subsequently amend lambs’ birth weight and body size. Therefore, the combined administration of these additives can be practiced during feed restriction.

The objective of this study was to investigate the effects of feeding Amaranthus hybridus chlorostachys grain (AG) with (+E) and without enzyme (−E) on performance, egg quality, antioxidant status and lipid profile of blood serum and yolk cholesterol in laying hens. A total of 960 white leghorn (Hy-line W-36) commercial layers (56 weeks) were divided into 10 groups with 8 replicates per group (12 birds per replicate, including 3 adjacent cages with 4 birds each). A completely randomized design was implemented with a 5 × 2 factorial arrangement of treatments consisting of five levels of AG (0, 100, 200, 300 and 400 g/kg) and two levels of multienzyme complex addition (0 −E and 0.25 +E g/kg) fed to the hens for 12 weeks (2 wk. adaptation + 10 wk. main experiment). Feed intake (FI) and percentage of hen day production (HDP) were not affected by main effect of the AG level, but egg mass (EM) and egg weight (EW) were decreased (p < 0.01), and the feed conversion ratio (FCR) was impaired (p < 0.01). EM, EW and FCR were improved by enzyme addition (p < 0.01). EM, EW and FCR were affected (p < 0.01) by the interaction of AG and enzyme addition. The highest value of EM and the lowest value of FCR were observed in hens on the diet containing 200 g/kg AG with enzyme addition. Egg yolk cholesterol content was reduced (p < 0.05) by up to 10% with increasing levels AG in experimental diets. The egg quality traits, including Haugh units of protein quality, strength and shell thickness, were not affected by the main effects or interaction of AG and enzyme consumption. Amaranth feeding led to a decrease (p < 0.05) in triglyceride (TG) and low-density lipoprotein (LDL) while also promoting increases (p < 0.05) in the high-density lipoprotein (HDL) and total antioxidant capacity (TAC) of the blood. A comparison of the effects of contrasts showed that functional parameters (except FI), yolk cholesterol, antioxidant parameters (except MDA) and blood lipid profile had differed significantly (p < 0.05) between the hens fed amaranth versus those not fed amaranth. These findings indicate that feeding a diet containing up to 200 g/kg of AG with enzyme addition can improve EW, EM and FCR. Feeding laying hens diets containing AG also positively influenced blood traits and antioxidant status in laying hens while reducing egg yolk cholesterol content.
