Mature Size

Taylor (1980) indicated the importance of mature size in the description of animals and its usefulness for standardising growth parameters. The mature size and body composition of the Gallego breed, a small meat-producing type first described by Mason (1967), have never been estimated under defined management conditions. Therefore, using the scaling rules and results of Thonney, Taylor, Murray and McClelland (1987) as a guide, a study was made to determine whether the reputation of Gallego lambs for producing lean carcases was borne out in the composition of mature animals.Twenty-one ewes (mean liveweight, LW, 32.7, sd 5.4 kg) and eight rams (LW 47.6, sd 8.6 kg) were selected as cast animals on the basis of age ( >4 years), body condition score (BCS, >1.75), health and teeth status and group-fed on concentrate (180 g crude protein/ kg dry-matter) and hay ad libitum. LW was measured fortnightly. When all animals had a LW and BCS which were stable for 2 months, 3 subgroups were slaughtered monthly. Weights of wool, body organs and hot carcase (HC) were recorded. Dissection of the cold carcase (CC) into commercial joints (Cabrero Poveda, 1984) and total lean, bone and fat.

Live Export

An experiment was conducted at Rutherglen Research Institute in autumn 1979 to evaluate various grain supplements for the fattening of 18-month-old Merino wethers intended for the live export market. All sheep had mature, dry pasture, harvested during mid summer, freely on offer. This herbage contained 9% crude protein and was 47% digestible. Wheat, oats or lupins were fed as supplements at 0, 180, 360, 540 g/head.d and ad libitum. Mixed grain rations were also studied: lupins were fed at 0, 90, 180 and 270 g/head.d with either wheat or oats ad libitum. Wethers were fed these rations for nine weeks and fasted liveweight, wool growth, and body condition score were measured. Animals were then slaughtered and carcases weighed. Animal performance was positively related to the rate of grain intake. Ad libitum intakes of wheat and oats were low - 450 and 520 g/head.d respectively, and only maintained liveweights. in contrast, lupins fed ad libitum were consumed at 650 g/head.d, which resulted in significant increases in live and carcase weight - 4 kg and 3.8 kg respectively. Pasture intake was reduced by one third with all ad libitum grain rations. The addition of lupins at 180 g/head.d to wheat or oats increased the ad libitum intakes of the cereal grains to 550 and 650 g/head.d, respectively, with associated liveweight gains of 1.0 and 4.5 kg for the nine week period. Intake of cereal grains was generally low compared with that in other published reports; but all rations containing more than 10% lupins showed promise as supplements for fattening wethers.

Daily Milk Yield

The effect of restricting the intake of pasture on the performance of dairy cows was studied in two 28-day phases in the eighth and ninth months of lactation. Intakes ranged from 12.4 to 4.9 kg of dry matter/cow day-1. After the 28-day restriction phases, all cows were grazed ad libitum at pasture. Production of milk, butterfat, protein and solids-not-fat all declined linearly with reduction in intake (0.569, 0.0286, 0.0206 and 0.0525 kg per kg of dry matter intake, respectively). Butterfat concentration increased curvilinearly with reduction in intake, but there was no effect on protein and solids-not-fat concentrations. In addition to the decreased production, there was a decrease in body condition score of 0.160 units for each kg reduction in dry matter intake. During the post-experimental period, with ad libitum grazing, cows that had previously been restricted recovered most of their daily milk yield and some of their body condition. The cows in this experiment required an extra 35 kg of dry matter to produce an extra kg of butterfat, but this efficiency ignores potential extra production in the following lactation from improved body condition.

Condition Score

ABSTRACTA number of possible indices of body composition (live weight, skeletal size, total body water as estimated by deuterium oxide dilution, blood and red cell volumes as estimated by Evans Blue dilution, ultrasonic measurements of subcutaneous fat depth and eye-muscle area, and body condition scoring) was examined using 73 non-pregnant, non-lactating, mature cows of Hereford × Friesian, Blue-Grey, British Friesian, Galloway and Luing genotypes, ranging in body condition score from 0·75 to 4·5. Direct measurements of body composition in terms of water, fat, protein and ash were made following slaughter.Live weight, deuterium oxide dilution, ultrasonic measurements of subcutaneous fat depth and eyemuscle area, and body condition score were all considered to be potentially useful predictors of body composition. Combinations of techniques offered better predictions than did any single index. Using a combination of measurements it was possible to predict body fat and protein with a residual s.d. of 13·1 kg and 3·15 kg respectively. Breed differences in the partition of fat among the main adipose tissue depots necessitated the development of specific prediction equations for body fat based on condition score and subcutaneous fat depth for different breeds. Equations remain to be developed for predicting body composition in cows in different physiological states.

Abstract Twenty-five Dorper (D), 27 Katahdin (K), and 33 St. Croix (S) ewes were used to characterize changes in BW, body condition score (BCS), body mass index (BMI), and body composition with different nutritional planes before breeding. Supplement treatments were soybean meal fed at 0.16% BW and 25% soybean meal and 75% ground corn at 0.8% BW (DM; L and H, respectively). There were two animal groups and pens per breed and supplement treatment. Shrunk BW (20 h without feed and water), BCS (1–5), linear measures including wither height and length from the point of the shoulder to pin bone, and body composition via urea space were determined after 0, 4, and 8 wk. Initial values were 62.10, 59.99, 61.57, 62.25, 50.23, and 52.98 kg shrunk BW (SEM=3.601); 35.82, 34.81, 35.57, 36.41, 33.77, and 34.09% fat (SEM=1.043); 17.06, 16.72, 16.98, 17.27, 16.38, and 16.49 MJ/kg energy (SEM=0.357); 3.29, 3.41, 3.29, 3.29, 2.99, and 3.18 BCS (SEM=0.139); and 13.72, 14.22, 12.69, 12.81, 11.53, and 11.50 g/cm2 BMI (BW/(height×length); SEM=0.463) for D-L, D-H, K-L, K-H, S-L, and S-H, respectively. Change from wk 0 to 8 was -0.80, 2.90, -2.74, 3.33, -2.02, and 3.36 kg shrunk BW (SEM=0.842); -0.14, 2.03, -1.45, 1.70, -0.85, and 2.10 kg fat (SEM=0.862); -8.4, 83.7, -62.5, 73.8, -38.4, and 88.1 MJ energy (SEM=33.30); -0.02, 0.20, 0.04, 0.29, -0.08, and 0.17 BCS (SEM=0.070); and -0.265, 0.297, -0.185, 0.491, -0.571, and 0.587 g/cm2 BMI (SEM=0.488) for D-L, D-H, K-L, K-H, S-L, and S-H, respectively. Correlation coefficients between change in BCS and mass of water, fat, and energy were 0.35 and 0.44 (P ≤ 0.004), and those for BMI were 0.54 and 0.56, respectively (P < 0.001). In conclusion, a BMI can be more highly related to and predictive of change in body composition of hair sheep resulting from different nutritional planes compared with BCS.

Condition Score

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.
