Harvesting of wild ruminants occurs to an appreciable extent in several countries, but the potential world production of meat from these animals is greatly in excess of the current yield. Any increase in the utilization of this important source of protein may be obtained by either an increase in the cropping of present animal systems or through the introduction of changes such as those imposed ...

The objective was to determine which tissue components contributed to the reduction in carcass yield of immunologically castrated (IC) barrows when compared to physically castrated (PC) barrows. The carcass yield of an IC barrow is less than the carcass yield of a PC barrow. This has historically been attributed to the presence of testicles, but the testes have only accounted for approximately ...

ABSRACT The present experiment was designed to evaluate the effect of different protein and energy levels on broilers performance under hot climatic conditions. A total of three hundred Ross-308 chicks were selected on basis of uniform starting live bodyweight (45g/chick) proximately. Chicks were randomly divided into three treatments with five groups of 20 chicks per pen. Diets were formulated...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

in 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mtc-mibi scan is performed. the nodules are divided to hot (10), warm (12) and cold (8). fna reported papillary ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary ca and 3 benign lesions). all the nodules with no mibi uptake...

The objective of this study was to estimate genetic and phenotypic correlations of body weight at 6 weeks of age (BW6), as well as final carcass yield, and moisture, protein, fat and ash contents, using data from 3,422 F2 chickens originated from reciprocal cross between a broiler and a layer line. Variance components were estimated by the REML method, using animal models for evaluating random ...

Accurate prediction of meat yield in live animals may allow more efficient genetic improvement of meat yield in farm-raised catfish. An initial trial with 30 channel catfish demonstrated significant correlations among weight-adjusted residuals for muscle area measured from transverse ultrasound images and transverse sections at five locations along the trunk musculature (r = 0.30 to 0.70). Rela...

The aim of the present study was to evaluate the impact of zilpaterol hydrochloride (ZH; 0 or 10 mg/lamb daily) and soybean oil (SBO; 0 or 6%) supplementation on feedlot performance, carcass traits, and wholesale cut yield of 32 Dorper × Pelibuey ewe lambs (30.55 ± 2. 57 kg of initial BW). Lambs were blocked by BW and randomly assigned to treatments under a randomized complete block design with...

Relationships among different stress parameters (lairage time and blood level of lactate and cortisol), meat quality parameters (initial and ultimate pH value, temperature, drip loss, sensory and instrumental colour, marbling) and carcass quality parameters (degree of rigor mortis and skin damages, hot carcass weight, carcass fat thickness, meatiness) were determined in pigs (n = 100) using Pea...

background and objectives: amygdalus with a number of endemic species grow vastly in iran. edible sweet almond (a. communis), is cultivated in many countries due to its pharmaceutical, nutritional and cosmetic importance; while almond oil which is rich in oleic acid is known for its economic interest. in the present study, the amount and constituents of oil of six amygdalus species including a....
