Evaluation of the New York City COVID-19 case investigation and contact tracing program: a cascade of care analysis.

Background: New York City (NYC) was the first COVID-19 epicenter in the United States and home to one of the country's largest contact tracing programs, NYC Test & Trace (T2). Understanding points of attrition along the stages of program implementation and follow-up can inform contact tracing efforts for future epidemics or pandemics. The objective of this study was to evaluate the completeness and timeliness of T2 case and contact notification and monitoring using a "cascade of care" approach.

Animal protein-soybean oil-based broiler diet optimizes net profit at the expense of desirable ω-6 fatty acids from the breast muscle of the broiler chicken.

Total 288 Ross-308-day-old male broiler chicks were randomly distributed into six dietary treatment groups in a two-way ANOVA with 2 × 3 factorial arrangements (two factors, i.e., dietary protein and energy having two types of protein, e.

Nutrient content and degradation study of some unconventional feed resources of Bangladesh.

This study aimed to evaluate six unconventional feed resources of Bangladesh, including water hyacinth (), banana leaves (), roadside grass (), bamboo leaves ( Scrad), Seaweed ( sp.) and sugarcane bagasse (). Evaluations were based on dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), ash content, DM and OM digestibilities and fractional rate of degradation.

Effects of genotype, parity, season and their interactions on milk yield in crossbred dairy cattle.

The crossbred dairy cattle (CDC) have been gaining popularity in the tropical countries for their increased milk yield within a short period of time because of heterogenic additive gene action. Hence, we aimed to investigate whether genotype, parity, season and their interactions had any effect on average daily milk yield (ADMY) of the CDC in a dairy farm at Chattogram district, Bangladesh, for a period of 3 years from January 2016 to December 2019. Total 16,425 retrospective lactation records of 150 multiparous Sahiwal × Friesian (Sahiwal = 50%, HF = 50%), Local × Friesian (Local = 50%, HF = 50%) and Local × Friesian (Local = 25%, HF = 75%) CDC from the first to the third parities (50 for each parity) were collected from the farm records.
