Effects of essential oil compounds (EOC) on feed intake, ruminal fermentation, growth performance, and carcass characteristics were determined using 60 lambs (24.6± 0.77 kg initial live weight, LW) fed either a barleyor corn grain-based diet without supplementation (control), or supplemented with 0.2 g/kg (DM basis) of carvacrol (CAR) or cinnamaldehyde (CIN). The experimental diets were arrange...

The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...

OBJECTIVE The study examined the effect of condensed tannins (CT) containing Ficus infectoria and Psidium guajava leaf meal mixture (LMM) supplementation on nutrient metabolism, methane emission and performance of lambs. METHODS Twenty four lambs of ~6 months age (average body weight 10.1±0.60 kg) were randomly divided into 4 dietary treatments (CT-0, CT-1, CT-1.5, and CT-2 containing 0, 1.0,...

Crossbred ewe lambs initially weighing approximately 90 lb (41 kg) were fed rations varying in roughage level prior to breeding to examine the influence of level of dietary energy upon subsequent reproductive performance when bred as lambs. In the two trials conducted over a 2-year period 200 spring-born Iambs were placed in four lots of 25 lambs each year and received rations containing 12% cr...

The study was established in local farm sheep Muwafaqia / Wasit - Iraq, from 1/10/2018 until 15/1/2019, to evaluate the effect of adding selenium with or without Vitamin E on some physiological characteristics Awassi male lambs. Sixteen lambs were selected after weaning an average weight (24.30) kg and aged (3-4) months. All fed 2% body a concentrated diet randomly divided into (4) groups. Cont...

abstract this study aimed to investigate the effects of different levels of the amino acid lysine on growth performance, feed efficiency and body composition of juvenile snow trout (schizothorax zarudnyi). for this purpose, 150 fish with average weight 22.51±0.28 g fed with five levels of dietary amino acid lysine including 0 (control), 7, 12, 17 and 22 g/kg diet, for 8 weeks. fish fed two time...

the object of this study is to evaluate the influence of silymarins from cultivated and wild silybum marianum l. plants with different content of flavonolignans, especially silibinin on serum lipids levels and on the experimental atherosclerosis development in rabbits fed on high cholesterol-diet (hcd). forty eight male six-months-old white new zealand rabbits (1.8-2 kg) were randomly assigned ...

this experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (ca) in canola meal-based diets severely limited in available phosphorus (pa) on growth performance, plasma phosphorus (p), and tibia ash (ta) in broilers from 22 to 42 d of age. two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. the exper...

The influence of medium-chain fatty acids (5% coconut oil) introduced in a starter diet (ALc) for 21 d after weaning was investigated in 230 Lacaune male lambs. They were weaned early, intensively fattened during winter and slaughtered at a constant live-weight (39 kg). Comparisons have been made regarding the individual growth rates and carcass qualities with an isocaloric and isonitrogenous r...
