Effect of roasted cereals and soybean in feed mixtures on fattening and slaughter traits as well as blood composition in fattening lambs
The study examined the effect of raw and roasted cereals (corn, oat and barley) and soybean in diet on growth performance and blood parameters of lambs fattening. Totally 60 lambs after ablactation at average of 50 days, were tested and equally divided into three groups: an experimental I (E I), experimental II (E II) and a control (C) group. The fattening period lasted 56 days. Lambs of the C ...
متن کاملRearing, fattening performance and slaughter indicators of lambs after selenium, zinc and vitamin E supplementation
The experiment was conducted on 80 Polish Merino ewes, their 82 lambs and 40 fattening rams. Merino ewes were divided into two groups: experimental (E) and control (C), each composed of 40 animals. Four weeks before lambing, 1 day, 3 weeks and 6 weeks after lambing 40 ewes of the experimental (E) group received intramuscular injection of 5 ml 0.1 % Na2SeO4 (selenium [Se]: 2.09 mg), 10 ml 10 % Z...
متن کاملRelationship between growth during the fattening period and lung lesions at slaughter in swine
The examination of lung lesions on fattening pigs at slaughter is a useful tool for estimating the importance of respiratory diseases in a farm. The aim of this study was to evaluate the relationship between prevalence and extent of lung lesions at slaughter and the previous pig growth during the fattening period. Data were collected on near of 7000 pigs from 14 French farms, individually ident...
متن کاملAccuracies of Genomic Prediction of Traits Associated with Lactation and Reproduction in Yorkshire and Landrace Sows
and Implications Genomic prediction involves statistical methods to estimate the genetic merit of selection candidates based on genetic markers spaced across the genome. The benefit of genomic prediction depends on the accuracies with which we can predict the genomic estimated breeding values (GEBV) of selection candidates based on their marker genotypes. The objective of this study was to esti...
متن کاملThe use of passive injectable transponders in fattening lambs from birth to slaughter: effects of injection position, age, and breed.
A total of 1,159 Tiris half-duplex passive injectable transponders (PIT) of 32-mm length were used to study the electronic identification of 618 fattening lambs of two breeds used for different production purposes (Ripollesa, meat breed, n = 271, and Manchega, dairy breed, n = 347). The lambs were s.c. injected in the armpit and the retro-auricular positions at 2, 15, and 30 d of age. All lambs...
