متن کاملPropolis or cashew and castor oils effects on composition of Longissimus muscle of crossbred bulls finished in feedlot
The natural additive products (propolis or essential oils), in replacing antibiotics, could be used as an alternative for feed strategies to improve animal production. This work was performed to evaluate the effect of natural additives as propolis or essential oils on meat quality of crossbred (Aberdeen Angus vs. Nellore) bulls. Thirty bulls were kept in feedlot (individual pen) for 55 d and ra...
متن کاملProduction system and slaughter age effects on intramuscular fatty acids from young Tudanca bulls.
Thirty-three young bulls from Tudanca local breed were used to investigate the effect of two production systems (semi-extensive vs. intensive) and two slaughter ages (12 vs. 14months) on meat fatty acid (FA) composition. Longissimus thoracis from semi-extensive animals had a lower percentage of intramuscular fat (p≤0.001), saturated FAs (p≤0.05), trans-18:1 (p≤0.001), n-6/n-3 ratio (p≤0.001) an...
متن کاملProductive performance of Holstein calves finished in feedlot or pasture.
