Potencyand Geneticdiversity of Bali Cattle Handiwirawan, Eko; ., Subandriyo
Indonesian Bulletin of Animal and Veterinary Sciences Vol 14, No 3 (2004)
Publisher : Indonesian Animal Sciences Society

Bali cattle are important indigenous cattle due to high population and wide spread in Indonesia. Increasing meat and cattle imports to fulfill the local demand should be able to motivate related parties to improve productivity of Indonesian cattle through good management, including Bali cattle. Several good characteristics are possessed by Bali cattle, particularly the adaptation capability in environment with poor feed quality and they possess good fertility. The government decision to determine Province of Bali is as a protected zone for other cattle breed in order to conserve Bali cattle is very reasonable considering that Indonesia is the gene center of Bali cattle and the first domestication place of Bali cattle . Genetic improvements ofBali cattle have been done at pure breed zone (Province of Bali) through selection and progeny testing at P3Bali and succeeds in obtaining cattle with good Estimated Breeding Value. Elite bulls obtained through the program are expected to be able to entirely improve Bali cattle in Indonesia through Artificial Insemination program. The improvement of genetic quality by crossing with Bos taurus and Bos indicus have been done at livestock sources regions and have been able to produce crossbred having good productivity as final stock. There is tendency to continuously improve the genetic composition ofBos taurus through artificial insemination at farmers level. The ideal genetic composition of crossbred needs to be evaluated to reach optimal genotype composition. Key words: Bali cattle, conservation, genetic improvement

Publisher : Indonesian Animal Sciences Society

Reproductive performance of small ruminants was evaluated in an on-farm multidisciplinary research project, known as the outreach pilot project (OPP), involving village farms in West Java, Indonesia . Strategies to increase production of small ruminants were implemented in this project . Data from three consecutive years (1986-87, 1987-1988 and 1988-1989) showed no significant increase in flock size . Average number of ewes per farm per month (EA) was 4 .1 . Although on average, larger farms had lower flock performance, a few individual farms with large flocks performed outstandingly in both reproduction and production . Twenty-eight percent of the farms had averaged 10 month lambing intervals (LI) with a potential of 3 lambings every 2 years (8 months interval) . Most of the differences between years were mainly due to changes in farm average litter size (FLS) (P<0.05) and changes in lamb mortality (%M) (P>0.05) : from 1 .33 and 20.5% to 1 .57 and 10 .4% ; for averages of FLS and %M between years 1986-87 and 1987-89, respectively. These changes were reflected in an increase in the number of lambs weaned per year per ewe available (LWEA) from 1 .19 in year 1 to 1 .60 in years 2 and 3, and were assumed to be promoted by the on-farm research program . Farms with large FLS in spite of higher %M, contributed a net improvement in LWEA and kilograms of lambs weaned. A different range of 3 .9-4 .5 kg of lambs weaned was found between the top 4 and the bottom 6 farms for FLS (averaging 2 .09 and 1 .19, respectively, for FLS) . Litter sizes 2 and 3 contributed substantial improvement in ewe productivity, weaning 18 and 23 kg of lambs, respectively .

Effects of grazing management and levels of concentrate supplementation on parasite establishment in two genotypes of lambs infected with Haemonchus contortus Ginting, Simon P; Pond, K.R; ., Subandriyo
Indonesian Journal of Animal and Veterinary Sciences Vol 2, No 2 (1996)
Publisher : Indonesian Animal Sciences Society

The effects of grazing systems, levels of feed supplementation and genotypes of sheep on the establishment ofHaemonchus contortus were studied in 36 St . Croix x Sumatra crosses (HC) and 36 Sumatra (S) male lambs . The lambs were artificially infected with Haemonchus larvae (L3) at a rate of 3,000 L3 per animal and fed concentrate supplement at 0 .5% body weight (BW) or at 1 .6% BW. The animals grazed clean Brachiaria brizantha pastures . Lambs grazing GM1 (grazing system with a 6-week rotational cycle) had egg counts of 3,936 t 1 .525 at week 18, and 29% of the lambs had PCV ranging from 7 .8 to 14 .6% . Lambs in GM3 (grazing system with a 12-week grazing cycle) had egg counts of 6,714 t 2,075 at week 28, and 24%ofthe lambs had PCV ranging from 7 .9 to 13.3% At these periods, all lambs in both GMI and GM3 were dosed with anthelmintics to prevent the death of the animals . Although the overall mean egg counts (4,543 t 318) of lambs on GM2 (grazing system with a Â 1-week grazing and 6-week resting periods) were higher (P<0 .001) than on GMI (2,944 t 325) or on GM3 (2,159 t 418), it was achieved without dosing with anthelmintics, since only I 1%ofthe Iambs in GM2ever reached PCV values less than 15%. Lambs fed supplements at 1.6%BW had lower (P<0.001) egg counts and higher (P<0 .001) PCV and serum protein than lambson 0.5 %BW supplement group . Egg counts and PCV values were not different (P>0 .10) between HC and the S lambs when fed supplement at 0.5% BW, but on 1 .6% supplement BW group, the egg counts were lower (P<0.001) in HC. It is concluded that a one-week grazing and a six- week resting system was superior than grazing systems with a 6- or 12-week rotational cycle . Improving the nutritional status of lambs by increasing the level of supplement offered could depress the establishment of Haemonchus in the Iambs . The HC and S lambs showed similar response to supplements at 0 .5% BW, but at 1 .6% BW the HC responded better than the S.

Growth curve is a figure of individual ability to express its genetic potential to maximum size under the existingenvironmental condition. Three non-linear growth curves, von Bertalanffy, Logistic and Gompertz, were used to analyze the weight-age relationship for five genotypes of sheep. The data were collected from IP2TP Sei Putih, North Sumatera. Num ber of animals which were collected consisted of five genotypes i.e, indigenous Sumatera (n=275), St. Croix (n=571), St. Croix Cross (n=899), Barbados Blackbelly Cross (n=471) and composite (n=740). The three non-linear growth curves were compared to obtain the most suitable curve for describing the shape of growth curves among sheep genotypes. The growth curves of von Bertalanffy fitted better than the others. The results showed that regression parameters of B or M (integral constante) were significantly different (P<0.001) among growth curves. It means that higher asymptotic weights will be followed by faster growth rates to reach mature size. Value of A (asymptotic mature weigh) and k (growth rate to mature size) were not significant (P>0.05). The data show that there was correlation between A and k.

Publisher : Indonesian Animal Sciences Society

Placing animals in cages with certain density and good grouping were two important aspects needed in intensive livestock production system to produce optimal production and animal welfare. The objective of this study was to examine effect of stocking density, breed and elapse of time on behaviour of newly regrouped, unacquainted adult rams from three sheep breeds i.e. Barbados Blackbelly Cross, Local Garut and Composite Garut, as possible factor causing variation in welfare status. Instantaneous scan sampling was used for recording sheep behaviour at three different stocking densities. Thirty-six adult rams were used in this research and divided into three groups (n = 12) on the basis of breed. At each stocking density four rams of the same breed were observed during two consecutive days. The recorded behaviours were agonistic-, self-care-, exploratory-, aberrant-, mating-, locomotive- and standing behaviour. The results showed that during the entire experiment agonistic behaviour was observed at the highest frequency. Stocking density was found to have a significant effect on exploratory-, locomotive- and standing behaviour. The effect of breed was found to cause significant differences in agonistic-, self-care-, aberrant- and mating behaviour. Significant differences were also found between day 1 and day 2 of regrouping for agonistic-, exploratory, self-care- and mating behaviour. It is concluded that the three breeds do differ in their behavioural reactions to different stocking density levels and time needed for adaptation after regrouping. Key Words: Sheep, Stocking Density, Behaviour, Animal Welfare

The use of blood protein polymorphism to estimate genetic distance among populations of Indonesian native sheep, St. Croix and Merino Suparyanto, Agus; Purwadaria, T; ., Subandriyo; Haryati, T; Diwyanto, K

The genetic distance among populations of Indonesia native sheep (Ciamis, Garut, Sumatera and Garahan), St. Croix and Merino were estimated to investigate the genetic relationship among those breeds. Blood protein polymorphism of transferin (Tf), post-transferin (PTf), albumin (Alb), post-albumin (PAlb) were detected from blood plasma, while haemoglobine (Hb) was detected from erythrocyte using Polyacrylamide Gel Electrophoresis (PAGE). Results of PAGE showed that Tf was controlled by 6 alleles, while Alb by 4 alleles, PTf by 3 Alleles and PAlb and Hb by 2 alleles. Value of breeding coefficient within individual subpopulations (FIS) for Tf (-0,0014), Alb (-0,0046) and Hb (0,0256) were not significantly different by noel. These results show that data of gene frequency are still following Hardy-Weinberg Equilibrium and inbreeding inside the sub population did not occur. The closest distance among the native breeds is the subpopulations of Ciamis and Garut due to neighboring area and similar traits of Thin Tail Sheep. The genetic distance of both population to Sumatera Thin Tail Sheep and Garahan Fat Tail are quite far. In addition to that results all Indonesian native breed were distinctly different from St. Croix and Merino.

A study was conducted to investigate the milk production capacity and preweaning performance of the prolific Priangan sheep, at sheep breeding station of the Research Institute for Animal production, Bogor using 126 ewes during three lambing periods in three consecutive years. The milk production was estimated weekly, started at day 7 after lambing date, till lambs were weaned at 90 days of age. The results showed that total milk production was significantly affected (P<0.05) by parity and the number of lambs born with average daily milk production of 519.5 g head-1 day-1. Estimated total milk production was 43.6 kg/lactation (N = 126; SD = 7.8; CV = 19.4%; range = 28.7-53.6 kg). According to the dam parity, the highest milk production was estimated at third parity (40.1 kg head-1 lactation-1), whereas on the basis of litter size, ewes with twin born lamb had the highest production (39.9 kg head-1 lactation-1). The preweaning lamb performance (weaning weight and preweaning daily gain) was significantly affected (P<0.05) by ewe parity, sex, litter size and type of birth and weaned, with the average weaning weight of 10.62 kg (N = 208; SD = 3.37; CV = 25.08%) and 130.9 + 41.8 g head-1 day-1 (N = 208; SD = 33.5; CV = 31.26%), respectively. Where as lamb birth weight was significantly affected (P<0.05) by ewe parity, sex and the number of lambs bornwith average of 2.39 kg (N = 208; SD = 0.66; CV = Â Â Â Â Â Â Â 9.8%).

Effect of different levels of social isolation on the acoustical characteristics of sheep vocalization SEC, Engeldal; ., Subandriyo; E, Handiwirawan; RR, Noor
Indonesian Journal of Animal and Veterinary Sciences Vol 18, No 3 (2013)
Publisher : Indonesian Animal Sciences Society

In farm animals, vocal analysis is accepted as a non-invasive method for assessing animal welfare in comparison to most physiological measurements. The aim of this study was to investigate the influence of different degrees of social isolation on the acoustic characteristics of stress-induced bleats from three different breeds of sheep. The experiment consisted of subjecting the animals to three different levels of social isolation during which both locomotive and vocal data were recorded. The data on locomotive behaviour was subjected to descriptive analysis while specialized acoustic software was used to measure a total of thirty-six parameters of recorded bleats. Descriptive analysis showed that the animals displayed more locomotive activity during partial isolation compared to complete isolation. Number of bleats during partial isolation was also found to be higher. The application of two-way analysis of variance showed a significant effect of isolation level and breed on both temporal and structural acoustic properties. Amplitude, power and time acoustic properties were found to affect acoustic quality of vocal responses to isolation, whereas frequency related properties were also found to be different significantly (P < 0.05) between breeds. From spectrogram analysis, the patterns of energy distribution within the calls proved to offer the most evident that differ between isolation levels and breeds. It was concluded that acoustic analysis can be helpful in revealing the affective state of socially isolated rams. Key Words: Sheep, Social Isolation, Vocalization, Behaviour, Animal Welfare

Publisher : Indonesian Animal Sciences Society

A calculation was made for the lactation curve of Priangan sheep using Wood equation to find out how much differences actual milk production of uncorrected ewes compared to those corrected using parity and litter size born. Milk production was measured using weighing of the lambs before and shortly after suckling, with average of daily and total milk production were 519.5 g/head and 43.6 kg head-1 lactation-1, respectively. The average of parameter a, which reflected milk production at the beginning of the lactation period was 6.296 that equivalent to 571.5 g/head and significantly affected (P<0.05) by parity. The b parameter which reflected the rate of milk increment at the beginning of the lactation period was found to be 0.528 and significantly affected (P<0.05) by parity. The c parameter which reflected the rate of milk decline at the end of lactation period was found to be -0.20 and significantly affected (P<0.05) by parity. The average persistency which reflected the duration of maximum milk production was found to be 22.58 days without any significant contribution of parity and the number of lamb born. The average time to reach maximum milk production was found to be at week 3.5 after lambing without any significant contribution of parity and litter size. The average estimation of maximum milk production was 708.4 g/head and significantly affected (P<0.05) by ewe parity. Â Key words: Milk production, lactation curve, Priangan sheep

The effect of the liver fluke Fasciola gigantica infestation on the leucocyte eosinophil cell profile on sheep Widjajanti, S; Estuningsih, S.E; ., Subandriyo; Piedrafita, D; Raadsma, H.W

Eosinophil is one of the major leucocyte cell in the blood which specifically reacted on parasite infection, thus it is important to determine its profile against the F. gigantica infection. The aims of this study is to determine the differences of the eosinophil count profiles on the different breed of sheep infected with F. gigantica and its relation with the resistance of sheep bred against parasitic disease. Four groups of sheep consist of Indonesian Thin Tail (ITT) sheep, Merino sheep, backcross sheep (10 families) and F2 sheep were infected with 300 metacercariae of Fasciola gigantica. The total sheep used in this trial is 621. Those sheep were observed for 12 weeks and the blood samples were collected every 2 weeks after infection. The results showed that total eosinophil counts in all infected sheep increased after two weeks post infection and ITT sheep showed the highest counts. On the other hand, the mean fluke counts on ITT sheep is the lowest compared with the other groups of sheep. Merino and F2 sheep had the highest mean fluke counts. Three families of backcross sheep had the mean flukes count similar to ITT sheep and the other 7 families were similar to the Merino sheep. In conclusion, the highest total eosinophil count at the early stage of infection on ITT sheep might be related with the genetic resistance, which was showed by the lowest flukes count, and the resistance was inherited to some of the backcross sheep, which had similar flukes count with ITT sheep. Â Key words: Fasciola gigantica, eosinophil, sheep
