Weaned British x continental crossbred steers (n = 108, 7 to 8 mo of age) of medium or large frame were used in a replicated experiment with a 2 x 4 factorial arrangement of treatments over 2 yr. Management regimens consisted of backgrounding for 150 d and finishing for 0, 30, 60, and 90 d. Carcass data were collected, and samples from the longissimus muscle were analyzed for long-chain fatty a...

The objective of this study was to test and validate electromagnetic scanning of whole pork carcasses in an on-line, integrated, industrial configuration. The electromagnetic (EM) scanner was installed in two pork processing facilities (Plant A and Plant B). Plant A was a small pork fabrication plant that further processed chilled pork carcasses. Carcasses were delivered to Plant A by refrigera...

Forty-eight bulls (335 +/- 8.6 kg of initial BW) were randomly assigned to 4 glycerin levels (0, 4, 8, and 12% of concentrate DM) with the objective of evaluating the effects of glycerin supplementation on performance, ruminal fermentation, metabolism, and carcass and meat quality in Holstein bulls fed high-concentrate diets. Concentrates were formulated to be isonitrogenous and isocaloric (ass...

Creatine and carnosine have been considered as valuable nutraceuticals in meat products for a long time. Creatine as energy buffer plays an important role in cellular metabolism and shows protective effects in neurodegenerative diseases such as Parkinson’s disease and Huntington’s disease. Carnosine has multiple physiological functions associated with anti-oxidation and anti-aging. Although cre...

Carcass and live measurements of 203 pigs representing seven genetic populations and four target live weights (100, 114, 128, and 152 kg) were used to evaluate alternative measures of carcass composition. Measures of carcass lean (fat tissue-free lean, FFLM; lipid-free soft tissue, LFSTIS; and dissected lean in the four lean cuts, DL), fat (total carcass fat tissue, TOFAT), and lipid mass (soft...

NAKEV, J., T. POPOVA and V. VASILEVA, 2009. Influence of dietary Betaine supplementation on the growth performance and carcass characteristics in male female growing-finishing pigs. Bulg. J. Agric. Sci., 15: 263-268 A study with 20 pigs (10 males and 10 females) of the genetic population Danube White x Landrace was carried out at the Agricultural Institute – Shumen. Both male and female pigs we...

In the current research, the polymorphism of FATP4 gene was analyzed in Erlang Mountainous chickens. A total of nine genetic variants were identified by FATP4 gene sequencing analysis across the chicken samples. Significant associations (p < 0.05) were observed for two SNPs (g.5608778C>T and g.5608814G>A in exon 6) with certain carcass traits (such as live weight, carcass weight, eviscerated we...

Twenty-four cull beef cows from the University of Florida beef ranches were selected in order to examine the effects of short-term feeding and postmortem aging on cull cow carcass characteristics and palatability attributes from selected muscles. Cull cows were randomly assigned to a treatment of 0, 42, or 84 d (n=8 each) on a limit fed concentrate ration of 25 lb/d prior to harvesting. Upon co...

The effects of the proportion of concentrates in grass silage-based diets and of restricted dry matter (DM) intake were examined using 156 Simmental cross Friesian steers which were initially 389 kg live weight. The animals were reared on high-forage diets until 14 months of age and were then given grass silage ad libitum and supplemented with rolled barley which constituted (1) 0, (2) 120, (3)...

A total of 144 male crossbred calves were allocated to four management treatments (bulls; steers; bulls implanted with zeranol at 100 d of age and re-implanted at 69, 93 and 56 d thereafter; bulls implanted with zeranol at 168 d of age and re-implanted at 93 and 56 d thereafter), and two pre-slaughter shipping treatments (minimum pre-slaughter stress with cattle shipped and slaughtered within 4...
