Evaluation of adding sodium stearoyl-2-Lactylate to energy-reduced diets on broilers’ development, nutritional digestibility, bacterial count in the excreta, and serum lipid profiles

The purpose of this study was to evaluate the outcome of sodium stearoyl-2-lactylate (SSL) supplementation to energy reduced diets on broilers’ growth performance, apparent nutrient digestibility, excreta bacterial counts, and blood lipid profile. A total of 700 one-day-old male (feather sexed) Ross 308 broiler chickens having an average body weight of 43 ± 1.2 g were randomly allotted to five (5) dietary treatments (7 pens/treatment). The treatments consisted of: (1) positive control (PC) (basal diet with metabolisable energy, ME = 3000 kcal/kg starter; 3100 kcal/kg grower; 3200 kcal/kg finisher), (2) negative control (NC) (PC − 50 kcal/kg), (3) SSL1, NC + 0.03% SSL, (4) SSL2, NC + 0.04% SSL, (5) SSL3, NC + 0.05% SSL. The PC group showed higher BWG (body weight gain) and lower FCR (feed conversion ration) than the NC group during days 1 to 7, and 7 to 21. SSL supplemented groups showed higher BWG and better FCR than the NC group, along with a linear increase in BWG and linear decrease in FCR during days 1 to 7 and 7 to 21. Furthermore, a linear increase in overall BWG was observed with SSL doses. Excreta microbial counts were not influenced by energy levels or SSL doses. In blood serum parameters, LDL (low density lipoprotein) cholesterol was reduced with a linear tendency by increasing levels of SSL supplementation. In conclusion, sodium stearoyl-2-lactylate supplementation showed better growth and nutrient digestibility in broilers’ at an early age.Highlights Emulsifiers can help broilers to utilise dietary energy more efficiently Sodium Stearoyl-2- Lactylate helped to increase energy and fat digestibility in broilers As a result, growth performance was improved through Sodium Stearoyl-2-Lactylate supplementation in broiler

Effect of Yeast Culture (Saccharomyces cerevisiae) Supplementation on Growth Performance, Excreta Microbes, Noxious Gas, Nutrient Utilization, and Meat Quality of Broiler Chicken

The study was conducted to test the effects of using yeast culture (Saccharomyces cerevisiae) as feed additive on the growth performance, noxious gas emission, utilization of nutrients, excreta microbial count, and meat quality of broilers. In total, 360 one-day-old Ross 308 broilers with average body weight (BW) of 42.90±1.43 g were randomly selected and allotted to two groups; they were fed either a basal diet (control) or a basal diet supplemented with 1% yeast culture (YC). Each treatment group had 10 replication pens and each replication contained 18 birds. The experiment was divided into 3 phases (1 to 7, 8 to 21, and 22 to 35 days) for growth performance observation. In the 1st phase (1 to 7 days), only the body weight gain (BWG) significantly increased (P<0.05) in birds with the YC diet compared to the control diet. Significant effects on BWG (P<0.05) and feed conversion ratio (FCR) (P<0.05) were seen in birds receiving the YC-supplemented diet in the 3rd phase (22 to 35 days) as compared to the control diet. In addition, during the overall period (1–35 d), BWG was significantly higher (P<0.05) and FCR was reduced (P<0.05). Throughout this experiment, the meat quality, nutrient utilization, noxious gas emission, and bacterial count in the excreta did not vary significantly between the groups. This study proved that a higher dose of YC (Saccharomyces cerevisiae) supplementation could maintain the consistent positive effect on broiler growth but eliminated the speculated outcomes on digestibility, bacterial count, or excreta gas emission

Effect of Detoxified Nano Sulfur Supplementation on the Growth, Nutrient Digestibility, Meat Quality, Excreta Microbes, Gas Emissions, and Blood Profiles of Broilers

A 35-day experiment was conducted to evaluate the effects of the supplementation of mineral detoxified sulfur dispersion ((DSD); Patent No.: 10-1997773) on the growth performance, meat quality, excreta microbiota, gas emissions, nutrient digestibility, and blood profiles of broilers. In total, 720 one-day-old ROSS 308 broilers, with an initial body weight of 41.9±0.8 g, were divided into two (2) treatment groups with 20 replicate pens/groups composed of 18 birds per pen. Treatments consisted of 1) CON (the control), normal drinking water and 2) TRT (the treatment group), CON+0.001% DSD (1000:1 dilution ratio). Average daily feed intake (ADFI) and feed conversion ratio (FCR) increased in the TRT group (P<0.05) between days 1 to 7 and days 7 to 21 of the experimental period. Similarly, body weight gain (BWG) showed a significant increase (P<0.05) in the DSD-supplemented group throughout in the length of the experiment. With regard to meat quality, redness (a*) was higher, while drip loss was lower, on the 7th day in the DSD group. Furthermore, DSD supplementation increased (P<0.05) Lactobacillus excreta but decreased E. coli concentrations in the TRT group compared to the CON group. Notably, nutrient digestibility, excreta gas emission, and blood profiles did not show any significant differences (P>0.05). DSD supplementation, administered through drinking water, has a positive impact on the growth performance, meat quality, and excreta microbiota of broiler chickens

Possibility of using glucose oxidase in the diet to improve selected indicators of blood antioxidant defense, digestibility and growth performance of broiler chicken

We conducted this experiment to establish a consistent result of dietary glucose oxidase (GOX) supplementation in broilers’ growth performance, nutrient digestibility, gas emission, caecum bacterial count, and antoxidant status. A total of 792 broilers of 42.38 ± 0.72 g average body weight (BW) at one-day old were fractionated into four treatment groups (18 birds/pen; 11 pens/treatment) named as 0%, Basal diet; 0.01%, basal diet + 100 mg/kg GOX; 0.02%, basal diet + 200 mg/kg GOX; 0.03%, basal diet + 300 mg/kg GOX. For growth performance, this 35 days’ experimental period was divided into three phases (d 1 to 7, d 7 to 21, d 22 to 35, overall). For the final phase, nutrient digestibility, gas emission, caecum bacterial count, and blood parameters were measured. GOX supplementation (0.02%, 0.03%) showed increased body weight gain (BWG) and reduced feed conversion ratio (FCR) during days 22 to 35 and in overall period. At the same time, linear increase of BWG and linear decrease of FCR were observed. Increasing doses of GOX showed linear improvement in dry matter digestibility and a tendency for a gradual increase in energy digestibility. On day 7, GOX supplementation (0.02%, 0.03%) reduced drip loss in meat with a gradual decrease. Blood antioxidant parameters of glutathione peroxidase (GSSG) and glutathione (GSH) were linearly increased by rising doses of GOX where 0.03% GOX had the highest value. In short, GOX supplementation brought improvements in digestibility and antioxidant capacity, which helped to increase body weight gain in broilers.Highlights Glucose oxidase enzyme supplementation could benefit growth performance in broilers Dietary addition of glucose oxidase could increase apparent nutrient digestibility in broilers As a health benefit, antioxidant status of broilers were improved with glucose oxidase supplementatio

Objective: The study was conducted to standardize the desire level of papaya latex on quality of cheese prepared from cow milk. Materials and methods: Cheese sample was prepared using whole milk collected from Dairy Farm, Bangladesh Agricultural University. This experiment was conducted on five treatments from cow milk named as sample CC1: cow control; A1: 2 drops (0.06 gm); B1: 3 drops (0.10 gm); C1: 4 drops (0.14 gm); D1: 5 drops (0.16 gm) of papaya latex. All experimental cheeses were judged by a panel of judges for organoleptic evaluation using a score card. The total solids and ash content of the different types of cheese were determined by oven drying method according to AOAC. Fat per cent, protein and acidity were determined by Babcock method, procedure and titrating with N/10 sodium hydroxide solution, respectively described by Aggarwala and Sharma. Results: There was significant difference within the overall physical score of different samples except color score. Overall score of sample B1 was highest (93.67&plusmn;1.53) and score of sample D1 was lowest (72.33&plusmn;12.01). In case of chemical analysis, the highest protein value was 17.14&plusmn;0.34% found in B1 and lowest value was 14.94&plusmn;0.16% found in D1. The highest fat value of sample B1 was 23.00&plusmn;1.00% and lowest value was 16.00&plusmn;1.00% found in C1. Highest carbohydrate was found in A1 (9.44&plusmn;2.25) and lowest in D1 (5.02&plusmn;0.04). Total solids and moisture content of cheese differed significantly (P<0.01) among the sample. On the other hand, non-significant difference was found in acidity. Conclusion: Cheese from cow milk, time on curd coagulation have significant difference (P<0.01) but non-significant difference was found in yield. Highest yield was found in sample CC1 (200.00&plusmn;5.00 gm/kg) and lowest yield was found in B1 (193.33&plusmn;2.89 gm/kg). [J Adv Vet Anim Res 2017; 4(3.000): 249-254

Influence of multiple showering on quality of buffalo semen during hot-humid season

Objectives: This experiment was conducted on buffaloes to see effect of showering on maintaining good quality of buffalo semen in hot season. Materials and methods: This study was conducted on 6(six) indigenous buffalo bulls in hot summer of March and April 2017. The effect of multiple showering vs single shower alone on fresh and equilibrated semen quality was observed. The buffalos were divided into similar two groups (according to age and weight) and housed in half-walled openshed with adequate spacing and the feeding management being identical. The bulls in the control group were allowed to a single shower at 10.00 am and experimental bulls were allowed to four showers at 07.00, 10.00, 13.00 and 16.00. Temperature and humidity were recorded during this time. The average temperature was around 35&#xb0;C along with 72% relative humidity. The quality of experimental bulls semen was evaluated in terms of volume, live sperm, sperm concentration, sperm motility, motion parameters and morphology for normal and abnormal sperm. For this analysis Computer Assisted Semen Analysis (CASA) system was used. Results: Between experimental group and control group semen quality differs significantly for volume (2.04±0.13 mL; 2.53±0.27 mL) (P [J Adv Vet Anim Res 2018; 5(1.000): 12-18

Health-related quality of life and coping strategies adopted by COVID-19 survivors:A nationwide cross-sectional study in Bangladesh

INTRODUCTION: This study aims to investigate the health-related quality of life and coping strategies among COVID-19 survivors in Bangladesh. METHODS: This is a cross-sectional study of 2198 adult, COVID-19 survivors living in Bangladesh. Data were collected from previously diagnosed COVID-19 participants (confirmed by an RT-PCR test) via door-to-door interviews in the eight different divisions in Bangladesh. For data collection, Bengali-translated Brief COPE inventory and WHO Brief Quality of Life (WHO-QoLBREF) questionnaires were used. The data collection period was from October 2020 to March 2021. RESULTS: Males 72.38% (1591) were more affected by COVID-19 than females 27.62% (607). Age showed significant correlations (p<0.005) with physical, psychological and social relationships, whereas gender showed only a significant correlation with physical health (p<0.001). Marital status, occupation, living area, and co-morbidities showed significant co-relation with all four domains of QoL (p<0.001). Education and affected family members showed significant correlation with physical and social relationship (p<0.001). However, smoking habit showed a significant correlation with both social relationship and environment (p<0.001). Age and marital status showed a significant correlation with avoidant coping strategies (p<0.001); whereas gender and co-morbidities showed a significant correlation with problem-focused coping strategies (p<0.001). Educational qualification, occupation and living area showed significant correlation with all three coping strategies(p<0.001). CONCLUSION: Survivors of COVID-19 showed mixed types of coping strategies; however, the predominant coping strategy was avoidant coping, followed by problem-focused coping, with emotion-focused coping reported as the least prevalent. Marital status, occupation, living area and co-morbidities showed a greater effect on QoL in all participants. This study represents the real scenario of nationwide health-associated quality of life and coping strategies during and beyond the Delta pandemic
