this project was conducted to evaluation the effects of replacement of barley grain with corn grain on fatteningperformance of male lambs. twenty five male lambs (6-7 month-old, average body weight = 31.22 ± 3.4 kg) were assigned randomly to five dietary treatments (5 lambs/treatment) in a randomized complete design. the first diet contained barley grain without corn grain but in the other diet...

Data from 644 exposures and 552 lambings were used to analyze reproductive traits of 1/2-Finnish Landrace, 1/2-Dorset ewes (1/2 Finn); 1/4-Finnish Landrace, 3/4-Dorset ewes, (1/4 Finn) and Dorset ewes. Ewes were exposed to Hampshire or Suffolk rams for spring lambing from 1973 to 1978. The analytical model included fixed effects of ewe birth year (EBY), ewe breed (BR), lambing year within EBY a...

The objective of the experiment was to determine the effectiveness of copper oxide wire particles (COWP) in pregnant ewes and safety to lambs. COWP have been used recently as an anthelmintic in small ruminants to overcome problems associated with nematode resistance to chemical dewormers. Doses of COWP (<or=4 g) have been used in lambs without clinical signs of copper toxicity. Use in pregnant ...

Pre-slaughter live weight, dressing percentage, and hot standard carcase weight (HCWT) from the 2007, 2008, 2009 and 2010 birth-years of the Information Nucleus Flock Lambs (n=7325) were analysed using linear mixed effects models. Increasing the sire breeding value for post-weaning weight (PWWT), and c-site eye muscle depth (PEMD), and reducing the sire breeding value for fat depth (PFAT) all h...

The somatogenic and galactopoietic effects of recombinant ovine placental lactogen (oPL) were compared with the effects of recombinant ovine growth hormone (oGH) in post-weaned growing lambs and in lactating ewes. In two experiments that each lasted 35 days, 2-month-old lambs were given daily subcutaneous injections (0.1 mg/kg live weight) of oPL or oGH, and their daily growth rates were compar...

Lambs were assigned to a 2x2 factorial design with corn or barley fed either whole or rolled. Hay was fed for ad libitum intake while concentrates were fed in similar amounts. Dry matter intake of hay, ADG, the gain:feed ratio, and warm carcass weight (WCW) were higher (P<0.05) for lambs fed corn than for those fed barley. Cereal processing had no effect (P>0.05) on hay dry matter intake, ADG, ...

The aim of the present study was to assess the effect of slaughter and carcass weight, age at slaughter and sex on the fatty acid profile of the Greek Boutsiko sheep breed. Twenty lambs (ten females and ten males) were examined. The lambs were slaughtered at the age of 48 days. Carcasses were chopped in nine specific cuts and a random sample of 100 g was taken from each cut, with a total of 180...

The physicochemical characteristics of the meat from lambs fed diets containing whole or disintegrated cottonseed, associated not with calcium lignosulfonate (LignoCaSO3), were evaluated. Thirty non-castrated Dorper x Santa Inês lambs, an average 24.9 ± 3.6 kg and four months age confined for 60 days in collective stalls distributed a completely randomized design six replications. After slaught...

this research was conducted to evaluate the effect of different zinc (zn) sources on performance, bloodmineral and cell counts of zandi lambs. 18 male lambs at weaning were supplemented with two differentsources of zinc, 25 ppm znso4 and 25 ppm zinc-peptide added to the basal diet as control. live bodyweight, weight gain and feed efficiency improved with zn-peptide supplementation (p

The purpose of this study was to investigate the effect of different corn processing methods on rumen microbial flora, histomorphometry and fermentation in fattening male lambs. Twenty male lambs (average age and weight of 90 days and 25.00 ± 1.10 kg, respectively) were used in a completely randomized design including four treatments and five replicates each over 80 days long period: 1) Lambs f...
