The aim of this study was to evaluate the viability of the use of spent laying hens’ meat in the manufacturing of mortadella-type sausages with healthy appeal by using vegetable oil instead of animal fat. 120 Hy-line layer hens were distributed in a completely randomized design into two treatments of six replicates with ten birds each. The treatments were birds from light Hy-line W36 and semi-h...

We evaluated the nutritional value of broiler diets containing approximately 35% soybean meal from insect-protected soybean containing CrylAc protein, or from a similar nontransgenic control, or from 7 reference commercial soybean varieties. The feeding trial lasted 41 d, and each treatment consisted of 10 replicates of 1-d-old Ross 508 broilers (5 pens males and 5 pens females). Each pen conta...

This study investigated the effect of wild grape (Vitis coignetiae) dietary supplementation on the antioxidative potential and quality of the breast and leg meat of broilers. A total of 36 one-day-old male Cobb broiler chicks were obtained from a commercial hatchery, and randomly assigned to 9 pens with 4 birds per pen. Then, broilers were fed 3 different dietary supplementations, including 0%,...

The effects of ambient temperature (T; 18 vs. 28 degrees C), dietary energy level [E; 90, 100, and 110% of NRC (1994) recommendations], and dietary lysine level [LYS; 105 vs. 120% of NRC (1994) recommendations], and their interactions on feed intake, BW gain, feed:gain ratio, and carcass yields of male turkeys were studied from 29 to 140 d of age. The experiment was designed as a split plot, in...

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...

An experiment was conducted to evaluate the carcass characteristics of Kanniadu kids under different housing systems viz., intensive, semi-intensive and extensive system of rearing. Twenty-four weaned Kanniadu kids were selected at random and they were allotted to three different treatments, comprising of eight animals in each group. The dressing percentage of intensive and semiintensively rear...

This study examined the effects of stocking density on live performance, physiological stress level indicators, and processing yields of male broilers grown to 1.8 kg. A total of 3,120 Ross x Ross 708 male chicks was placed into 32 floor pens (5.57 m2/pen). Stocking density treatments were 25, (75 birds/pen), 30 (90 birds/ pen), 35 (105 birds/pen), and 40 (120 birds/pen) kg of BW/m2. The BW gai...

Some feedstuffs containing significant levels of fiber may be a good source of bioactive compounds that may contribute to improving broiler meat quality. However, high fiber level can have a negative impact on broiler performance. A study was undertaken to investigate the impact of incorporating citrus pulp (5 or 10%) or dehydrated pasture (5 or 10%) on the performance, carcass yield, and chara...

Poultry meat is very susceptible to oxidation because of the high concentration of polyunsaturated fatty acids, which negatively affects the quality and nutritional values of chicken meat. Coccidiosis is the most common parasitic disease of poultry. Intending to limit anti-parasites usage in poultry feed and also because of the concerns about antibiotic resistance and residues in poultry produc...
