The Ability Of The N-Alkane Technique To Estimate Intake And Diet Choice Of Sheep, R. M. Lewis, A. M. Magadlela, N. S. Jessop, G. C. Emmans

Department of Animal Science: Faculty Publications

This study assessed the efficacy of the n-alkane technique to estimate intake and diet composition in animals given single foods or a choice of two. In thefirst experiment intakes of pelleted ryegrassand lucerne, given eitheralone or as a choice, were measured in lambshoused indoors in individual pens. Each of the three feeding treatments was given to 12 lambs at two degrees of maturity (0.30 and 0·45 of estimated mature sizes). The 12 lambs were constituted as three replicates of the two sexes of each of two breeds. The measured intakes werecompared with those estimated using the n-alkanes C31 andC33, found …

Detection Of Listeria Monocytogenes In Faeces From Chickens, Sheep And Cattle In Elazığ Province, Hakan Kalender

Turkish Journal of Veterinary & Animal Sciences

Faecal samples collected from 206 chickens, 170 sheep and 130 cattle were investigated for the presence of Listeria monocytogenes in animals slaughtered at local abattoirs in Elazığ. The prevalance of L. monocytogenes was 4.36% in chickens, 0.58% in sheep and 1.53% in cattle. Of the 12 L. monocytogenes isolates, seven (58.33%) and five (41.66%) belonged to serotypes 1 and 4, respectively. Other species isolated were L. innocua, L. welshimeri, L. seeligeri, L. murrayi and L. grayi. These results indicate that animal faeces could be a source of contamination of carcasses with L. monocytogenes and may lead to foodborne listeriosis.

Turkish Journal of Veterinary & Animal Sciences

To determine the relationship between biochemical parameters and production traits in sheep, 111 of the animals raised in the Bandırma Sheep Research Institute were used as living materials. The blood samples of 31 Hampshire Down x Merino, 33 Dorset Down x Merino, 27 German Black Headed x Merino and 20 Border Leicester x Merino crosses were taken. Transferrin (Tf) and haemoglobin (Hb) types were determined. Some production traits such as greasy fleece weight, staple length, fiber diameter, ondulance and lamb birth weight were estimated. Important correlations between Hb AB and lamb birth weights (P < 0.05), Hb AB and greasy fleece weight in SBA x Merino crosses (P < 0.05), Hb AB and greasy fleece weight in Border Leicester x Merino crosses (P < 0.05), Tf B type and greasy fleece weight in SBA x Merino and Border Leicester x Merino crosses (P < 0.05) and Tf A type and lamb birth weight in SBA x Merino crosses (P < 0.05) were also determined.

Department of Animal Science: Faculty Publications

The objective was to determine the effect of periods of adjustment and duration of performance test on estimating genetic variance parameters for ADG. Variance components were estimated from ADG data collected from 1978 to 1984 on a total of 1,047 Targhee ewe and ram lambs at the U.S. Sheep Experiment Station (Dubois, ID). Across all years, lambs averaged 84 ± 9 d of age and 25 ± 5.4 kg of weight when placed on test. Lambs were provided ad libitum access to a commercial pellet of barley grain and ground alfalfa for 14 wk. Every 2 wk, ADG was recorded. …
