“…The dressing percentage was gradually increased due to gradual increase of concentrate supplementation (Table 3). The dressing percentage of present study was higher than the value for Black Bengal goat and cross bred (41.48% to 43.73%) observed by Abedin et al (2005), Moniruzzaman et al (2002) and Das et al (2005). However, a lower dressing percent and age of Black Bengal goats (38.61%) was also reported by Singh et al (1986) in Indian Black Bengal goat.…”

Fifteen castrated male goats (12.97±1.46 Kg) aged between 12 and 13 months were used to study the effect of different levels of concentrate supplementation on growth performance and nutrient digestibility in Black Bengal goat under stall feeding. The feeding trial was continued for a period of 75 days where goats were supplied at the rate of 158g DM/kgW .75 /day. The animals were assigned into five dietary treatments: A (Only dal grass as sole feed), B (15% DM from concentrate + 85% DM from dal grass), C (20% DM from concentrate +80% DM from dal grass), D (25% DM from concentrate + 75% DM from dal grass), E (30% DM from concentrate + 70% DM from dal grass). Digestibility of all nutrients was gradually higher (P<0.01) from A to E. Total live weight gain of goats of group A was statistically lowest (P<0.01) than those of other groups. There was also significant difference (P<0.01) among the treatment groups E, D, C and B. Live weight was gradually increase due to gradual increase of concentrate from B to E. Nitrogen balance, carcass yield and net profit of treatment group E was highest (P<0.01) then D, C and B than A. Green grass do not fulfill the appetite and nutrient requirements as a sole feed. Concentrate supplementation is undoubtedly essential to fulfill the nutrient requirements and concentrate can be supplemented upto 30% of required DM to obtain the best result.

“…Spleen of the present study was almost similar but shank was differed to Sultana et al (2010), where they showed that shank % was 1.2, 1.8 and 2.2 at 6, 9 and 12 months of age, respectively. Moniruzzaman et al (2002) stated that slaughter age had a significant effect on dressing percentage and meat quality.…”

The aim of this study was to identify optimum slaughter age on carcass traits and meat quality of Jamuna basin lambs. Thirty lambs were divided into three age groups like T1 (6 months), T2 (9 months) and T3 (12 months) having ten lambs of each treatment. Parameters studied were carcass traits, proximate component (DM, CP, EE, and Ash), physicochemical (Ultimate pH, cooked pH, cooking loss, drip loss, water holding capacity-WHC), sensory attributes (color, flavor, tenderness, juiciness, overall acceptability) and instrumental color values (L*, a* and b*). Hot carcass weight and dressing% were found significantly (p<0.001) higher in T3 than T1 and T2 treatments. Edible by products namely viscera, head, leg, pluck, neck, shoulder, rack, loin, kidney, heart, liver, lungs and shank from three treatments were found significant effect (p<0.001). Inedible by products viz. blood, skin and spleen were found significantly higher (p<0.001) with the advancement of age. Dry matter (DM) of T2 and T3 were found significantly lower (p<0.001) than T1 treatment. Crude protein (CP) and ether extract (EE) were significantly increased (p<0.001) of advancement of age of lambs. Drip loss of T2 was found significantly lower and WHC of T2 was significantly (p<0.001) higher than other two treatments. Cooking loss and ultimate pH of T3 were significantly (p<0.001) lower than other two treatments. Color, tenderness, juiciness and overall acceptability were significantly differed (p<0.001) and flavor was significantly differed (p<0.001). The instrumental color values L* decreased whereas a* and b* and chroma values were significantly (p<0.05) increased with the advancement of age of lambs. The saturation index was significantly (p<0.001) higher in 6- and 12-months age than 9 months of age. It is revealed from the study that 12 months of slaughter age showed better in terms of productive and meat quality traits. Therefore, 12 months of age may be recommended as optimum slaughter age for Jamuna basin lambs. SAARC J. Agric., 19(2): 257-270 (2021)

ObjectivePurpose was to determine the effects of grazing system and floor type on concentrations of blood metabolites, activity of creatine kinase, body weight and carcass characteristics of castrated Nguni goats.MethodsForty eight, 7 month old goats were randomly allocated to herding and tethering treatments from 0800 to 1300 hours and accommodated on slatted and earth floors daily. Blood samples were collected by jugular venipuncture every fifteenth day for metabolite analysis. Slaughter was done at a commercial abattoir following 5 months of monitoring.ResultsTethered goats had significantly higher concentrations of urea (5.19 mmol/L) (p< 0.001), creatinine (55.87 μmol/L) (p<0.05), total protein (64.60 g/L) (p<0.01), and globulin (49.79 g/L) (p<0.001), whereas herded goats had higher glucose (3.38 mmol/L) (p<0.001), albumin (15.33 g/L) (p<0.05), albumin/globulin ratio (0.34) (p<0.01), and body weight (24.87 kg) (p< 0.001). Slatted floors caused higher (p<0.01) albumin at 15.37 g/L. The interaction of grazing system and floor type affected creatinine, total protein, globulin at (p<0.01) and albumen/globulin ratio at (p<0.01). The least creatinine concentration and albumin/globulin ratio was in herded and tethered goats that were accommodated on earth floors, respectively. The highest total protein and globulin concentrations were in serum of tethered goats that were accommodated on earth floors. The highest (p<0.05) dressing percentage (45.26%) was in herded goats accommodated on slatted floors.ConclusionHerding of goats lowered globulin concentration, improved estimated feed intake, blood glucose and albumin concentrations, albumin globulin ratio, increased body weights and weight related carcass characteristics. Floor type had very little effects on metabolites where earth floors only reduced albumin concentration. Tethering and housing goats on earth floors resulted in double stress that increased chronic infections.
