AIM To study the impact of deficiency of second line limiting amino acids (SLAA; valine, isoleucine and tryptophan) on the production performance and carcass characteristics of commercial broilers. MATERIALS AND METHODS A control (T1) corn-soy diet was formulated to contain all essential AA on standardized ileal digestible basis; While in T2-a 'moderate SLAA deficit' diet was formulated by re...

the effect of dietary terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 japanese quails was studied from 21 through 49 days of age. dietary treatments included four levels of terbutaline [0 (t0), 1 (t1), 3 (t3), and 5 (t5) mg/kg of the diet]. quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

Abstract Objectives of this research were to compare carcass characteristics, cutting yields, and meat quality for market barrows gilts. Commercially-sourced carcasses from 168 175 gilts weighing an average 107.44 ± 7.37 kg selected 17 different slaughter groups representing approximately 3,950 carcasses. Each group was sorted into percentiles based on hot weight with equal number each quartile...

Results of this study indicate that correlations between real-time ultrasound loin depth and carcass loin muscle area and between carcass loin depth and carcass loin muscle area are high. However, using carcass loin muscle area as the true value, the standard error of prediction for real-time ultrasound loin muscle area was lower than those for loin muscle areas predicted from either real-time ...

The genetic traits of a purebred bull convey the reproductive and economic value to buyers. This study examines and compares the value of actual production weights (birth, weaning, and yearling weight), production expected progeny differences (EPDs) (birth, weaning, milk, and yearling), and ultrasound EPDs (carcass quality predictors) for purebred Angus bulls sold at auction. One EPD, birth wei...

Objective: A research was carried out to investigate the effects of nettle (Urtica dioica) powder (NP) and essential oil (NE) on performance, blood metabolites, carcass characteristics and antioxidant stability in broiler chicks. Methods: The treatments were T1: control diet, T2: control diet + 5g/kg NP, T3: control diet + 10 g/kg NP, T4: control diet + 5g/kg NE and T5: control diet + ...

To study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (Ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). All treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called T1, 2T, T3 and T4 that were ad...
