Two trials examined genetic and environmental influences on muscle fiber type proportions. Trial 1 compared Polypay and Coopworth x Polypay male lambs either left intact or castrated early, mid or late in growth. Trial 2 compared Hampshire-sired lambs (females, early castrate wethers and late castrate wethers) from Suffolk x Coopworth dams and whiteface x Coopworth dams. Half the lambs in each ...

Forty cross-bred western wether lambs were divided into two equal groups. During a growth period, 20 lambs received a maintenance diet, and 20 lambs were fed an adequate diet. Four Iambs from each group were slaughtered after the growth period, and extramuscular adipose tissue lipoprotein lipase activity (LPL) and intramuscular lipid content were determined. Lambs from each growth phase group w...

The aim of the present study was to investigate the potential benefits of grazing lactating ewes and their lambs on chicory (Cichorium intybus). Fifty-six certified organic twin-rearing ewes were either drenched with an anthelmintic or not, within 2 days after parturition and were grazed upon either grass/clover or chicory pastures. Around 12 weeks after parturition a subset of 12 lambs per tre...

BACKGROUND [corrected] Anaplasma phagocytophilum (formerly Ehrlichia phagocytophila) causes the disease tick-borne fever (TBF) in domestic ruminants and has for decades been one of the main scourges for the sheep industry in the coastal areas of Norway. Current control strategies are based on reduction of tick infestation by chemical acaricides. METHODS In the present study, we investigated i...

Plasma aldosterone, sodium (Na) and potassium (K) concentrations, daily Na and K intakes, and urinary and faecal excretion were measured during the first week of postnatal life in 9 lambs naturally born at term (145 days of gestation) and in 10 lambs delivered by caesarean section on day 145 (6 lambs) or on day 139 (4 lambs) of gestation. Plasma aldosterone, Na and K concentrations showed no si...

Lifetime (5 yr) lamb production and wool production from 207 straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system were evaluated for ewe fertility, prolificacy, ewe fleece weight, and total lamb weight weaned per ewe exposed. Data included 2,620 ewe exposures, 2,384 parturitions, 4,638 lambs born, and 3,498 lambs weaned. E...

To test an artificial surfactant in vivo, six 120-d gestational age lambs were treated at birth with a mixture of a 9:1 M ratio of [14C]dipalmitoyl phosphatidylcholine (DPC) and phosphatidylglycerol at a dose of 100 mg DPC/kg. Nine other lambs were not treated. The mean PO2 values of the lambs treated with artificial surfactant were 65.7 +/- 11 mm Hg vs. 24.8 +/- 1.6 mm Hg for the untreated lam...

Thirty-two crossbred lambs (BW = 31.2 ± 4.7 kg; 16 females, 16 males) housed in individual pens were used to investigate the relationship between nutrient supply and taste preferences in ruminants. Experiment 1 determined whether an imbalanced CP supply would alter preferences for feeds containing flavors designed to elicit either umami (U) or a mixture (1/3:1/3:1/3) of umami, sweet, and bitter...

This study was conducted on 528 neonates of Pak-Karakul sheep born during February to April, 1998 at the Sheep and Goat Development Center, Rakh Khairewala, District Layyah, Overall mortality observed in neonates was 9.28%.The mortality rate in male and female neonatal lambs was 9.72 and 8.90%,respectively. The survived lambs were significantly heavier (3.77 ± 0.63 kg) (P< 0.001) than those die...

Pasteurella haemolytica is a major contributor to neonatal pneumonia in lambs; which continues to be a major problem. Experimentation was conducted to determine the efficacy of vaccinating pregnant ewes to reduce the incidence of pneumonia in newborn lambs. Vaccines utilized in this experimentation included three different commercial Pasteurella haemolytica vaccines intended for use in cattle a...
