Abstract

Lambs meat consumers prefer large loin chops that have limited external fat. Intense selection process, sometimes resulting individual gene mutation. The mutant allele could be used as a marker for specific characterization and for growth response to specific environment. The gene is identified as a single gene, and called as Callipyge. Genotyping analyses on reciprocal cross offspring showed that Callipyge locus flanked to markers of CSSM18 and TGLA122 from ovine chromosome 18. The sheep has extreme phenotype which similar with that of the cattle containing single gene of double muscled. Phenotype of ovine callipyge is expressed in heterozygote individual of CLPGP/clpgM produce from heterozygous ram for callipyge gene (CLPGP/clpgM) and normal ewes (clpgP/clpgM). Offspring ratio from the segregation pattern is 1:1. A mating between heterozygous animals (CLPGP/clpgM) or all Callipygous parents resulted on 25% Callipygous and 75% normal lambs. The ratio of Callipygous offspring phenotype is not following mendelian segregation. Some reports on characteristic analyses showed that the birth weigh of normal and Callipygous is not significant different. However, after weaning the growth rates of both lambs are different. The dressing carcass percentage of normal lambs (53.9%) is significantly lower than that of Callipygous (57.3%). The Callipyge gene express the body weigh from 20 to 69 kg. Its muscle weigh is 40% higher than normal lambs. The different of superficial gluteal, adductor tensor facia latae of Callipygous muscle with those of normal lambs are 63%, 47% and 22.3% respectively. The carrier lamb has less internal (pelvic fat) or external (loin) fats, but it has 43.0% larger of rib eye area.   Key words: Sheep, callipyge gene, heterozygote

Abstract

White duck Mojosari will own the good enough prospect when used as by component in forming of duck meat type. Egg production average was 224 eggs per bird per year, and its was competed with brown plumage. Average of egg weight is 65.15 ± 4.84 g, the length of egg is 54.95 ± 2.49 mm and wide surface of egg is 45.66 ± 2.33 mm. White plumage for laying duck type perhaps will be more a lot of constraint. Farmer habit for color pattern believed, that was as proudly varieties breeder on the each area. Serati duck still a lot of constraint because the consumer demand is more like with white performance and cleanness product. This condition was opinion by existence of chicken broiler which enough modern skill and progress in developed. The solution of overcome is crossing between white plumage duck and white plumage muscovy drake will very help to get the product desired by consumer. Expected of Serati duck could be developed for farm breeder industry and opportunities for the farmer business in villages.   Key words: Mojosari duck, feather color pattern, Serati, commercial

Abstract

Recessive homozygote gene (c/c) in poultry is usually expressed in white plumage, and thought to affect growth and egg production. This effect is still under discussion because can be positive or negative. In order to study further the expression of the recessive gene on Mojosari duck this study was aimed to investigate the quality of first eggs from ducks with brown and white plumage. The result showed that weight of first eggs of ducks with dominant gene (C/c), was 52.91 g higher than that of duck with homozygote recessive gene (c/c) which 51.43 g. For other variable, there was no significant different between ducks with dominant gene (C/c) and with recessive gene (c/c), i.e. weight of egg yolk (14.99 vs. 14.94 g), weight of egg white (31.34 vs. 29.94 g) weight of wet shell (6.62 vs. 6.56 g) and thickness (0.36 vs. 0.34). However there was significant different between the two group for score of Haugh Unit (89.67 vs. 101.12) and egg yolk color (7.30 vs. 5.35). It is obvious that the expression of the recessive homozygote gene (c/c) did not give any significant difference to the quality of first egg, except for the color which need to the confirmed with more and longer observations.       Key Words: Recessive Gene, First Eggs, White Mojosari Duck

Abstract

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.   Key words: Sumatera thin-tail sheep, crossing, non-linear growth

Abstract

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.   Key words: Indonesian native sheep, St. Croix, Merino, blood protein polymorphism, genetic distance

Abstract

Until recent, the biology data from white Mojosari duck have been never reported. Different from their sister, the brown Mojosari duck was establish for laying duck. Equation model of non-linier Wood was commonly used to predict the milk production curve. This method is possible for egg production of laying duck. The purpose of the research is understanding of production curve fitted and persistency. The data were collected from 39 birds of White Mojosari duck in Balitnak Ciawi. Four types of analysis data set, those are partial data (16 weeks), full data (52 week), collective and individual data of egg production. The equation of mathematic non-linier Wood is Y=AtBexp-kt by DUD method. The result show that egg production was 236 for 52 weeks record and twenty five percent were reached up than 290 eggs. Production trait will decrease on 4-5th month and after that slow up for increasing, but never came as high as the first and second month production. Estimation of A parameter is 5.5- 6.9 eggs per week, meanwhile the constantan of B is 1.0-1.1 and k is 0.007-0.02 respectively for production data. By percent, showed that A (83-84%), B (0.02-0.06) and k (0.006-001), that all for partial and full data. Genetic correlation between parameter A and B is negative, which is 0.94–0.098 (production data) and 0.24-0.76 respectively. Positive correlation was resulted between B and k parameters. But for A and k parameters were both are positive and negative result. Estimation of persistency was 3.8 weeks for individual data and 3.7 weeks for collective data by partial (16 weeks) data set. And than the fulldata (52 weeks) are 4.0 and 4.1 respectively for collective and individual data set.   Key words: White Mojosari duck, non-linear, production curve

Abstract

The morphological discriminant and canonical analyses were carried out to determine the genetic distance and discriminant variables between Indonesian breeds of thin tail sheep from Deli Serdang (North Sumatera), Ciamis and Garut (West Java) and fat tail sheep from Garahan and Pamekasan (East Java). The number of sheep randomly collected from farmers was 665 heads, while that from breeding station was 183 heads. Zoometrical variables studied were body weight, body length, wither height, chest depth, chest circumference, hip height, hip depth, hip circumference, tail length, tail width and tail thickness. SAS package program was used to analyze the data. Results from distribution mapping produced by canonical analysis and Mahalanobis distance (phenogram tree) showed that breeds are divided into two groups. The first group is thin tail sheep which consists of Ciamis, Garut and Sumatera, and the other is fat tail sheep which consists of Garahan and Pamekasan. The groups of Ciami and Garut were mixed by Garahan with 1.01 and 1.20%, respectively but were not contaminated by Pamekasan (0.00%). The highest similarity between individual inside the group was obtained from Sumatera (84.27%) due to the isolated flock. It was mixed more by Ciamis (7.87%) and Garut (5.62%) than Garahan (1.69%) and Pamekasan (0.50%). Results from canonical analysis also showed that body length, chest circumference, hip circumference, and body weight was less discriminant variables to determine the differences between breeds, while the most discriminant variables were obtained by tail length, tail width and tailthickness.   Key words : Sheep, genetic distance, morphology

Abstract

Under semi-intensive conditions, the composite genotype (K) (25% Barbados Blackbelly; BB, 25% St. Croix; SC, 50% Sumatra Thin Tail; DETS) showed relatively have similar weaning weight as compared to other contemporary crossbred, therefore under intensive conditions (confined), they are expected to have better performances. The objective of the study are to find performances of the second generation composite genotype lambs and the first generation performances of the ewes, as well as several genetics parameters under intensive conditions, and compared to the Barbados Blackbelly Cross (BC) as contemporary crossbred. The growth of pre- and post-weaning of BB crossbred (BC) and the second generation of composite genotype (K-F2) are relatively the same. Growth curve using Von Bertalanffy model with the equation of Wt (t) = A*(1-B*e**(- K*t)), show that the equation for BC is Wt (t) = 26.8(1-0.92e**(-0.01t) and for K-F2 is Wt(t) = 26.1(1-0.92e**(-0.01t). This equation indicate that the growth of BC and K-F2 is not significantly different. The BC and K-F2 genotype reach maturity at the weight of 26.8 and 26.1 kg, respectively, and both with rate of reaching maturity of 0.01. Mating weight and weight at lambing of those two genotypes are around 29 - 30 kg dan 31 kg, respectively. The mean of litter size of BC and K-F1 are 1.52 and 1.48, respectively or around 1.5. The average litter size at weaning are 1.39 and 1.34, respectively for BC and K-F1. This means that pre-weaning mortality are around 5.37 and 9.76%, respectively for BC and K-F1. The lambing interval of BC and K-F1 are 211 and 223 days, or 0.58 and 0.61 year, respectively. Therefore the reproductive rate (RR) of the respective genotype are 1.39/0.58 = 2.39 and 1.34/0.61 = 2.19, respectively. The average of litter weight at weaning (LWW) of BC x BC, SC crossbred (HC) x BC and K-F1 x K-F1 are 11.62, 12.60 and 11.83 kg, respectively. Therefore based on the ewe genotype the LWW of BC and K-F1 are 11.74 and 11.83 kg, respectively. Flock productivity (FP) for those two genotypes per year are 20.24 and 19.39 kg, respectively for BC and K-F1. Dam productivity index (DPI) that calculated as /ewe weight for those two genotypes are 0.67 and 0.66, respectively for BC and K-F1. Meanwhile, the flock efficiency index (FEI) that calculated as FEI = FP/ewe weight0.75 for the respective genotypes are 1.57 and 1.54 for BC and K-F1. The estimates of repeatability of litter weight at weaning show relatively low value (0,092), therefore the estimate of MPPA (Most Probable Producing Ability) for predicting the future productivity is relatively the same. The estimate of MPPA for litter weight at weaning (LWW) for the respective genotype are 11.79 and 11.81 kg, respectively for BC and K-F1. Results of the study show that performances of composite genotypes (F) and the contemporary crossbred (BC) are relatively similar in the traits of growth, dam productivity and the estimate of MPPA.   Key words : Composite sheep, performance of production and reproduction, intensif condition
