Feedlot Lambs

The study was conducted to evaluate the effects of feeding frequencies (one, two, three, and four times per day) on the performance of male feedlot lambs. Forty Santa Inês male lambs were used with an average age of 120 days approximately and initial body weight of 24.90 ± 1.8 kg (mean ± S.D.). The lambs were distributed to treatment groups in a completely randomized experimental design, with 10 animals per treatment, placed in individual pens. A standard diet consisted of Tifton-85 hay and concentrate with a ratio of 60:40, respectively. The different feeding frequencies did not influence (p > 0.05) the intake of nutritional components, blood parameters, weight gain, ingestive behavior, carcass characteristics, or meat quality of male feedlot lambs. The feeding frequency of 3 and 4 times per day promoted the highest digestibility of neutral detergent fiber (NDF; p = 0.008) and total digestible nutrients (TDN; p = 0.002). The feeding frequency of 3 times per day promoted the highest digestibility of crude protein (CP; p = 0.005). The time devoted to rumination (min/kg DM) was increased (p = 0.029) when the diet was supplied once a day compared to the other feeding frequencies. Based on these results, the recommended feeding frequency for male feedlot lambs is once a day. When feeding at this frequency, the ingestive behavior, productivity, carcass characteristics, and meat quality of male feedlot lambs will not be compromised.

Forty-one reindeer bulls (age 1 1/2 years) were subjected to different pre-slaughter treatments: herding for a short distance to a grazing corral, selection by use of a lasso, lorry transport and helicopter herding for 1, 2 and 3 days respectively. As control, 9 reindeer were shot without previous handling (in the mountains). The results indicated the traditional selection technique of using a lasso to be the most stressful and glycogen-depleting handling procedure so far studied. In the lasso-selected reindeer the lowest glycogen values and the highest ultimate pH values in the meat were measured. The values of the measured parameters indicating stress (aspartate aminotransferase (ASAT), urea, Cortisol and abomasal lesions) were also highest in these reindeer. By contrast, the modern method of herding by helicopter was not found to be detrimental to glycogen content, ultimate pH, the measured blood metabolites, or the frequency of abomasal lesions. In all treatment groups degenerative lesions were observed in the skeletal muscles. No relarionship between technological and sensory meat quality characteristics and skeletal muscle lesions in reindeer could, however, be found in this study. The study confirmed an earlier finding that a 'stress-flavour' could develop in reindeer meat after intensive pre-slaughter handling of the animals. Further study of when and how such "stress-flavour" develops ought to be undertaken.

Thirty reindeer bulls (age 1 1/2 years) were subjected to different pre-slaughter treatments to study the effects on ultimate pH values, muscle glycogen content, blood metabolites and abomasal lesions. Gathering and herding into a grazing corral were followed by various selection procedures. Before starting these, a control group of 10 reindeer were captured by lasso and slaughtered outside the grazing corral. Ten reindeer were then selected by hand from a small group of animals (100-150 head) in a small selection corral. Another 10 reindeer were selected from a large herd of about 1000-2000 animals, by the traditional technique of using a lasso. During a 6-hour selection, animals were captured and slaughtered after 1.5 hours (n = 2), 3-5 hours (n = 2), 5 hours (n = 3) and 6 hours (n=3) respectively. The results showed the technique of using a lasso to be stressful and glycogen-depleting, as the two lasso captured groups (the control group and the reindeer exposed to the protracted lasso selection) had the highest ultimate pH values and lowest muscle glycogen values measured. By contrast, the selection procedure where reindeer were captured by hand, was not found to be detrimental to glycogen content and ultimate pH values. Nevertheless, both selection techniques expose the reindeer to acute stress during the capture and manual restraint, which in the present study was reflected in high plasma Cortisol values in all treatment groups. The frequency of abomasal lesions was highest in the group of reindeer subjected to the prolonged selection procedure. No connection between technological and sensory meat quality was found in this study. The technique of selecting animals by hand ought to be further developed so that existing practical problems can be solved. The technique could then be recommended for wider use.
