ABSTRACT.- Ninety lambs reared on pastures were slaughtered for 2 y corresponding to 3 ages of slaughter: At weaning with 4 mo of age (4M), at 6-7 mo of age (6M), and at 12 mo of age (12M; last treatments were weaned at 4 mo). With the purpose of deseasonalizing high-quality meat lamb production in the year, the present work aimed to achieve hot carcass weight (HCW) of 18?20 kg on average in each lamb group. Hot carcass weight, carcass yield (CYd), subcutaneous tissue depth, leg, frenched rack, and loin weights were determined. After meat ageing for 7 and 14 d from the 3 groups of lambs, instrumental color, Warner-Bratzler shear force (WBSF), consumer sensory analysis (n = 200), and fatty acid profile of intra muscular fat (IMF) were determined on longissimus lumborum muscle. Lambs of 12M resulted in greater HCW (P < 0.05). The young lambs (4M) presented a greater subcutaneous fat coverage and CYd (P < 0.05). Lambs of 12M presented a greater proportion of legs (P < 0.05) regarding HCW. Meat color from 4M lambs was lighter (greater L* values) when aged for 7 and 14 d and showed lower WBSF values with 14 d of ageing (P < 0.05). A greater proportion of IMF (P < 0.05) was observed in 12M and 4M lambs, but the latter presented a greater proportion of conjugated linoleic acid (P < 0.05) and polyunsaturated fatty acid to saturated fatty acid ratio (P < 0.05). Older lambs (12M) showed a lower n6/n3 fatty acid ratio (P < 0.05) and a greater concentration of α-tocopherol (P < 0.05). Meat from the 3 groups of lambs was scored positively (i.e., at least between "I like moderately" and "I like slightly") for overall liking when evaluated by consumers. Although significant differences were observed among the 3 groups of lambs, slaughter age in lambs until 12M seems to have a minor effect on product quality from a practical standpoint. © 2024 Cougo, et al.

ABSTRACT. - Counting ticks on one side of a bovine has been widely used to estimate the overall number of ticks; however, the accuracy of this method has not been determined. This work aimed to evaluate the one-side technique for counting ticks, identify bovines with a higher level of infestation, and determine the prevalence of infestation of adults and calves. To evaluate the one-side technique, ticks were counted on both sides of 352 bovines from three farms in nine months, and total numbers were correlated with the numbers counted on the left sides. The intraclass correlation coefficients reached values >0.99 for all farms, independent of the season. These results demonstrated that counting ticks on one-side and multiplying by 2 is a reliable method for estimating the overall number of ticks. To evaluate the level of infestation of various bovines, ticks were counted monthly, for 12 months, on the same bovines from seven farms. An animal was considered highly infested if the Anscombe residuals from a negative binomial GLM were ≥4, at least 2×. The number of bovines with infestation levels higher than expected varied among farms from zero to 3. Using this method, it is possible to evaluate the most infested bovines in order to remove them from the herd. The prevalence of infestation in calves reached 100% in five of the seven farms and 3- to 15-month-old calves had significantly higher infestation than adults.
