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:
An outbreak of systemic granulomatous disease of unknown etiology was diagnosed in a dairy herd from Argentina. Eleven out of 211 cows manifested hyperthermia, depression, alopecia, pruritus, decreased milk production and death in most cases. During necropsy, multifocal petechial hemorrhages in glottis and vulva, white multifocal nodules in the liver and splenomegaly with subcapsular petechial hemorrhages were observed. Both kidneys were diffuse pale and enlarged. Systemic granulomatous hepatitis, myocarditis, pancreatitis and nephritis were observed. Water and food samples tested negative for Arsenic and T2 toxin, respectively. Fusarium equiseti was isolated from alfalfa hay samples. Vicia spp. was not consumed by the affected herd and no other cause of vetch-like disease was registered. Other causes of granulomatous lesions (Mycobacterium spp. and fungal infections) were discarded. The systemic granulomatous disease was suggestive of a type IV hypersensitivity reaction. Although the sensitizing agent was not determined, two components of the ration were suspected: cotton seed and bone ash. Both of them were introduced one month prior to the detection of the first affected cow and the disease resolved since they were removed from the diet. |
