Organoleptic and physico-chemical evaluation of capretto baladi goats : a value-added meat alternative in an extensive rearing system

الملخص EN

The local Baladi breed is considered a common source of fresh meat in Lebanon.

Due to the extensive rearing system and the scarcity of pasture, kids resulting from multiple births are not reared, though cultural preference for young meat may valorize these twin kids as an expensive delicacy.

Few studies observed growth parameters, physical-chemical and sensory properties of meat in Baladi kids.

Therefore, 24 male Baladi kids were fed milk ad libitum post-natally for 24 days, after which 9 were randomly selected and fed pasture grass ad libitum and goat milk (Control), and 15 were fed only milk (Capretto) twice per day.

Animals were slaughtered at 4, 6 and 8 weeks of age and body organs compared.

Feed intake was measured by weighing kids pre- and post- feeding, and body weight measured twice per week.

Meat chemical properties were total ether-extracted fat, kjeldhal protein, and minerals.

Meat organoleptic properties were evaluated by consumers for color, taste, odor, richness, juiciness, tenderness and overall appreciation, as cooked by housewives or professionals.

Data were analyzed as a CRD using SPSS 10.0 and presented as LSMeans ± SEM.

Results showed that Capretto consumed increasing levels of milk from 4 to 8 weeks, with ADG decreasing (P<0.05) from 4 to 8 weeks.

Capretto showed 5% less (P<0.05) weight than control kids.

Carcass yield was higher (P< 0.05) for Capretto (44.5 ± 3.4 %) than control (36.3 ± 3.3%), with Capretto showing smaller viscera and lower hemoglobin.

Both blood and meat (protein, cholesterol) composition did not differ (P>0.05) between Capretto and control, although capretto showed lower (p<0.05) meat fat content than control kids.

Meat organoleptic characteristics were desirable at weeks 4 and 6 for both Capretto and control kids, whereas only Capretto meat stayed desirable at week 8.

To conclude, Capretto kids have similar properties to their traditional counterparts, with added desirable properties for a longer growing period, in addition to the increased health benefit of lower fat content.
