“…Jamuna basin lambs achieved average daily gain (ADG) 46-55g in active growing phase and marketed for slaughter at 9-12 months of age weighing about 15-18 kg (Hashem et al, 2020). The body weight information can be used in determining the value of animals and efficiency of rearing (Sun et al, 2020). Sheep farming has been also significant in the development and economic growth in different developed countries.…”

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)

“…The weight order among Nodes 1-4 was found to be Node 1<Node 2<Node 3<Node 4 (Adjusted p=0.000, F=32.37, df1=3, df2=148), because of the significant differences in BW. Nodes 5,7,9,11,12,13,14,15,16,17,and 18 were the terminal nodes. The CHAID algorithm declared HG as the most significant predictor of live BW.…”

“…In the literature, various reports found a great figure for the estimation of live BW using the main predictors, such as morphological and testicular measurements in different sheep and goat breeds. Different researchers used various statistical techniques, that is, correlation analysis [3], principal component analysis in multiple linear regressions [4], and simple and multiple linear regressions [5][6][7][8][9] for live BW prediction. In terms of the classical assumptions, the Chi-square automatic interaction detector (CHAID), exhaustive CHAID, classification and regression tree (CART), and artificial neural network (ANN) types, such as the radial basis function (RBF) and multilayer perceptron with one (MLP1) and two (MLP2) hidden layers, have recently been used to perfectly indicate the body measurements in relation to live BW in sheep and goat breeding studies [10][11][12].…”

Body weight prediction using different data mining algorithms in Thalli sheep: A comparative study

Background and Aim: The Thalli sheep are the main breed of sheep in Pakistan, and an effective method to predict their body weight (BW) using linear body measurements has not yet been determined. Therefore, this study aims to establish an algorithm with the best predictive capability, among the Chi-square automatic interaction detector (CHAID), exhaustive CHAID, artificial neural network, and classification and regression tree (CART) algorithms, in live BW prediction using selected body measurements in female Pakistani Thalli sheep. Materials and Methods: A total of 152 BW records, including nine continuous predictors (wither height, body length [BL], head length, rump length, tail length, head width, rump width, heart girth [HG], and barrel depth), were utilized. The coefficient of determination (R2), standard deviation ratio, root-mean-square error (RMSE), etc., were calculated for each algorithm. Results: The R2 (%) values ranged from 49.28 (CART) to 64.48 (CHAID). The lowest RMSE was found for CHAID (2.61), and the highest one for CART (3.12). The most significant predictors were the HG of live BW for all algorithms. The heaviest average BW (41.12 kg) was observed in the subgroup of those having a BL of >73.91 cm (Adjusted p=0.045). Conclusion: Among the algorithms, CHAID provided the most appropriate predictive capability in the prediction of live BW for female Thalli sheep. In general, the applied algorithms accurately predicted the BW of Thalli sheep, which can be very helpful in deciding on the standards, available drug doses, and required feed amount for animals.

“…Sheep has a major share of the animal protein industry, although meat quality is affected by a variety of factors. Several factors, such as species, gender, growth rate and maturation, diet, genetic factors, disease status, medication and hormone use, rearing conditions, temperature, relative humidity, and general husbandry practices have direct and indirect effects on meat quality (Hashem et al, 2013;Hossain et al, 2021a and2021b;Moniruzzaman et al, 2002;Rana et al, 2014;Baset et al, 2003;Sarkar et al, 2008;Sun et al, 2020), resulting in changes in meat consumption or marketing. Meat quality and price are affected by carcass weight.…”

The study was undertaken aiming to study the effect of age on carcass traits and meat quality of Barind sheep of Bangladesh. Ninety six male lambs were reared by 16 farmers at two upazila namely Paba and Godagari in Rajshahi district. Lambs were slaughtered at 6 (T1 ), 9 (T2 ) and 12 (T3 ) month‘s age. Each farmer kept 6 lambs (Two lambs for each 3 age category). Four types dressing percentages were measured; DRSWIEO (on the basis of slaughter weight and hot carcass weight including edible offal), DRSWEXEO (on the basis of slaughter weight and hot carcass weight excluding edible offal), DREMIEO (On the basis of empty body weight and hot carcass weight including edible offal) and DREMIEO (On the basis of empty body weight and hot carcass weight excluding edible offal). All lambs received maternal milk and a supplementation of commercial concentrate @ of 1.5% of live weight up to slaughter and allowed to graze for 8 hours a day on natural grassland. The Redness (a) was more (18.80±0.06) in 12 month‘s lamb and Yellowness (b) was higher (10.17±0.06) in 6 month‘s lamb. Ultimate pH (pHu ) varied significantly among age groups and it was lowest (5.62±0.01) at 6 month and highest at 9 month. Drip loss (DL) was highest on young and lowest in aged lambs. Dry matter (DM) and Crude protein (CP) both were varied significantly (p<0.05) in age groups showing highest DM (27.64±0.06%) and CP (23.61±0.03%) in young (6 month of age) lambs for both attributes. Minerals (Ash) was highest (0.89±0.06%) in aged (12 month of age) group and lowest (0.78±0.01) in young (6 month of age) and it was differed significantly (p<0.01) among treatments. Cooking loss (CL) and Ether extract (EE) were not differed (p>0.05) among treatments. The panel of examiners was attracted more to the color of aged lambs (12 month of age) and acquiring number (4.43±0.03) was varied significantly (p<0.01) among ages. Flavor was varied significantly (p<0.05) among ages tended to secure more point for 9 month lambs. Overall acceptability was differed significantly (p<.01) among ages and meat of 9 month lamb showed highest (4.57±0.03) acceptance.
