This research aimed to estimate the repeatability and MPPA values of Sapudi ewes based on the lamb’s daily gain from birth to pre-weaning and weaning. Using recorded data in a pedigree of lamb, 53 data with half-sib relationship came from 14 ewes which included the record of body weight gain of Sapudi lambs from birth to pre-weaning and weaning. Th...

Context 1
... of weight gain for pre-weaning and weaning can be seen in the appendix. And the value of weight gain for weaning and weaning is presented in Table 1. ADG can be used as a benchmark to determine the ability of livestock to convert nutrients contained in feed into the meat during pre-weaning and weaning. ...Context 2
... body weight of the lambs was measured during the pre-weaning period (0-2 months) and before weaning (0-3 months) using standard scales in kilograms (kg). The average daily weight gain of pre-weaning and weaning of Sapudi lambs is listed in Table 1. Daily body weight gain was calculated from the recorded weights of birth weight until a certain age, while in this study using pre-weaning ADG data which was calculated by pre-weaning weight minus birth weight and divided by age, while weaning ADG was calculated from weaning weight scales minus birth weight divided by age. ...Context 3
... results of the study showed that the average daily body weight gain was higher than the research by Ilham (2017) with the results of the relative body weight gain of local sheep kept in pastures in the pre-weaning period (aged 1-13 weeks) in the dry season for males and females were 53.71 g/day and 61.15 g/day respectively, in the rainy season 55.71 g/day and 69.24 g/day respectively. Table 1 shows the sequence of parent that has the highest mean value, according to the results of the study, there were 3 broods with daily pre-weaning weight gain above the population average (094, 28, 058), 3 broods with an ADG value equal to the population average (11, B1, 23) and 8 other parents had a mean value below the population mean (51, 17, 1530, 14, A35, 103, 123, 310). ...Context 4
... high average value of daily weight gain for pre-weaning is thought to be good traditional maintenance, so that the nutritional intake for lactating cattle in UPT PT and HMT Jember is quite good, this is in accordance with the three pillars of animal husbandry, that are good feed, good seeds, and good management. The average value of daily weaning body weight gain in Table 1 shows an evenly distributed value between parents, the values ranged from 0.09kg/day and the lowest was 0.05 kg/day with data on the actual weaning weight gain of 0.05 kg/day to the highest 0, 09 kg/day was measured at the time of weaning, with a population average value of 0.07 kg/day of weaning body weight gain. Table 1 shows 9 parents having values above the population mean with eartags (094, 058, 11, 23, 17, 1530, A35, 103, 310), three parents with values equal to the population mean value (28, B1, 14), two parents were below the population mean with eartags (51,123).Weaning data show an increase in the value of ADG compared to the period before weaning, this is not in line with the results of Ilham's research (2017) which shows that the body weight gain of local sheep decreases gradually until the 13th week of both the dry and rainy seasons and after that, it does not show any further increase or increase. ...Context 5

Several non-technical factors are thought to influence the level of pre-weaning and weaning ADG which is sometimes not proportional to the birth weight value. ...Similar publications

Indonesia has several types of local sheep, including Sapudi sheep. In increasing sheep production and population, it is necessary to pay attention to the reproductive system. The metabolism and physiology of pregnant sheep will experience changes which cause blood components to also change. The research sample was 20 Sapudi ewes from UPT. Livestock Breeding and Forage in Jember. Mother sheep were divided into 5 groups according to their reproductive phase, namely non-pregnant mothers, early pregnancy, mid-pregnancy, late pregnancy, and lactating mothers. The research variables are blood components which include erythrocytes, leukocytes, hemoglobin and hematocrit. The research method is quantitative descriptive which is analyzed using one-way variance, and if it is significantly different, the Duncan test is continued. The results of this study showed significant differences (p<0.05) in hemoglobin, while there were no significant differences in erythrocytes, leukocytes and hematocrit (p>0.05). The average hemoglobin value in the five reproductive phases is between 7.65-10.50 g/dL, erythrocytes 5.78-6.95 106/mm3, leukocytes 8.05-13.71 106/µL, and hematocrit 24.35 -29.70%.
