Efforts to Increase the Success Rate of Artificial Insemination on Small Ruminant
Full text linkThe success rate of artificial insemination (AI) technology in Indonesia is still low, especially on small ruminants. At experimental station condition, it was reported that the success rate of intrauterine AI was high (78.9% lambing percentage), while intracervix AI technique was still low (47.6% lambing percentage). Various things that could affect the success rate of AI program are discussed in this paper. Efforts to improve the success of artificial insemination in small ruminants (goats and sheep) can be done through the selection of productive female with good reproductive cycle, accurate dose of hormonal synchronization, followed by proper estrous detection and semen placement at the right time. Each stage is still open for more detailed study in order to obtain satisfactory results. Key words: Artificial insemination, small ruminant, success rat
Growth characterisics of Garut sheep and its crossbred
Full text linkBased on previous study it is agreed that Von Bertalanffy model is the best fitted growth curve model with highest acuracy compared to Gompertz or Logistic models. For that reason in this study Von Bertalanffy model was used to study growth characterisics of Garut sheep and its crossbred. Relative superiority of crossbred sheep compared to Garut sheep in mature size parameter (A) based on Von Bertalanffy model were respectively: M. charolain X Garut = 19.26%; Hair sheep X Garut = 8.08% and MG X HG or HG X MG = 4.22%. While relative superiority of crossbreds compared to Garut in rate of maturing (k) were respectively: MG = -4.91%; HG = -1.34% dan MHG/HMG = 6.05%. Based on its relative superiority mature size parameter (A) and rate of maturing (k) MHG sheep had prospect for more developed due to its performance in term of high mature body weight, faster in reaching standard of slaughter body weight (35 kg) at 440 days, and it is considere as more eficient in biological and economicaly.

Characteristics of Body Measurement and Shape of Garut Sheep and Its Crosses with Other Breeds
Full text linkIt is important to know body measurement because it could be used to estimate body weight as well as to differentiate the chrateristic of body measurement and shape of animal due to different breed or environment. This research was carried out to study morphometric characteristic of body size and body shape from 78 of Garut sheep (GG), 29 HG sheep {crossbred between St. Croix (HH) and Garut sheep (GG)}, 36 MG sheep {crossbred between Mouton Charollais (MM) and Garut sheep (GG)}, 62 MHG sheep (MG x HG) and 38 HMG sheep (HG x MG). Body part measured were wither height (X1), rump height (x2), body length (X3), chest width (X4), chest depth (X5), hip width (X6), chest girth (X7), cannon circumference (X8) and hip length (X9). Data obeserved were analised using t test and Principle Components Analysis (PCA). Based on PCA it was showen that chest girth was the primary identity for body measurement on males and females of Garut, HG, MG, MHG and HMG with its Eigenvector value 0.689; 0.709; 0.689 and 0.681 respectively. The primary indentity for body shape of Garut sheep were chest girth and hip heigth with Eigenvector value -0.600 and 0.551 respectively. The primary indentity for body shape of HG sheep were body length with Eigenvector value -0.725. The primary indentity for body shape of MG sheep were chest girth, rump heigth, and wither heigth with Eigenvectors value: -0.600; 0.558 and 0.555 respectively. The primary indentity for body shape of MHG sheep was wither height with Eigenvector value 0.608. The primary indentity for body shape of HMG was body length with Eigenvector value 0.764. Body shape of HG and MG sheep is different than that of Garut sheep, but the body shape of MHG and HMG were close to Garut body shape. This result indicated that the adaptability to environment of HMG and MHG is close to that of Garut sheep. Key words: Sheep, Body Size, Body Shape
Growth curve analysis of Garut sheep and its crossbreds
Full text linkData of body weight of Garut sheep and its crossbreds of 488 head, consist of 149 head of Garut sheep, 115 head of St. Croix X Garut (HG), 68 head of Mouton Charollais X Garut (MG), 101 head of MG X HG (MHG) and 55 head of HG X MG (HMG) which is collected from Indonesian Research Institute for Animal Production at Bogor station were used in individual growth curve analysis. Three growth curve non linier model were used in this study i.e Logistik, Gompertz and Von Bertalanffy models. Comparisons were made among these models for goodness of fit, biological interpretability of parameters and computional ease and effect of genotype and environment in them. Least square means growth curve parameters which have biological interpretability were used to compare effect the genotype, interse mated procces and estimated heterosis effect. The result indicated that Von Bertalanffy was the best model in fitting the data from Garut and Crossbreds although the model needed more iteration than others in computations. All models have good biological interpretability especially for parameter mature size (A) and rate of maturity (k). Genotype, year of birth, sex and type of birth reared were important effects (p0.01) in mature size (A) for all models except effect of type of birth rearing (P0.05) in Logistic model. Year of birth had important effect (p0.01) in rate of maturity (k) for all models. Genotype, year of birth, sex, parity and type of birth reared also had important effect (p0.01) in parameter b/M; except b parameter in Von Bertalanffy was affected significantly by sex (P0.05).

Prevention of Productive Cows Slaughter through Management of Local State Enterprises
Full text linkBased on the last national livestock census in 2013, the population number of cattle and buffalo have reduced by 15% compared to that in 2011. The highest reduction happened in Java that reached around 24-27%, while that in Bali and Nusa Tenggara was 25%. One of the reasons was caused by decreasing number of cows due to the increase of productive cows slaughtered every year. Number of cows slaughtered in Bali, Nusa Tenggara, and South Sulawesi had reached on average of 72% from total slaughtered, where more than 90% were productive cows. Reasons for slaughtering productive cows were due to: (1) Lower cows price; (2) Limited bulls supply; (3) Local government regulation on inter-island trade; (4) Weak and inconsistent law enforcement; and (5) Lack of understanding on criteria for productive cows by farmers. Increased rate of slaughtered cattle and increasing rate of inter-island trade volumes that higher than the rate of cattle population had caused the decrease of national cattle population. There are currently needs to improve and develop operation slaughter-houses under management of local state enterprise. The management applies on certain mechanisms that sort of incoming productive females according to different grades into allowable to be slaughtered and selected for breeding females, which could be further traded inter-island as supplier of cows for other regions. This strategy may help the central government to meet the demand for productive cows, particularly in Sumatera and Kalimantan which have abundance of feed biomass resources. Policy support is needed as instruments for all interested stakeholders including those who are willing to invest in cattle development such as oil-palm estates
Differentiation of three sheep breeds which have a genetic relationship by body sizes
Full text linkSumatera Composite (SC) sheep and Barbados Black Belly cross (BC) sheep are two sheep that have half the genetics of Sumatera local (SL) sheep. Populations with partially the same genetic composition are sometimes difficult to distinguish. Based on female body size sheep, an analysis was carried out to distinguish the three breed sheep that have genetic relationship. The research was conducted using SC, BC and SL ewe measured in body weight and 8 body sizes. Analysis of variance and canonical discriminant analysis, Mahalanobis distance, plotting canonical and dendogram were performed by SAS software ver. 9.0. Body weight and all body sizes of SC and BC sheep were significantly different from SL sheep. Canonical discriminant analysis successfully could differentiate among the three sheep breeds that have genetic relationship. The results of genetic distance estimation showed that SC sheep had genetic closeness to BC sheep compared to SL sheep. The size of the skull length, body weight and chest girth were the breed differentiation variable in this study
Lambing behavior of Garut ewes and its crosses with St. Croix and Moulton Charollais
Full text linkLamb mortality is highly related to ewe behavior at lambing. The purpose of this research was to study ewe lambing behavior and lamb behavior after birth of Garut (GG) sheep and its crosses with St. Croix (HH) and Moulton Charollais (MM). The number of observation were 106 head, consist of 32 GG; 23 of HG; 14 of MG; 31 of MHG and 6 of HMG crossed ewes. Analysis of variance of general linear model (GLM) for different number of sample was used to study ewe behavior of different group of ewes. Linear regression was used to analyze relationships between lambing behavior; times from birth to stand up and ewe body weight. While relationship between labor time and parity or type of birth were analyzed descriptively. Before lambing, ewes stood up, lain down, walked in circle, vocalized, urinated, flehmened, and pawed. HG and HMG ewes stood up less often than other breeds (P0.05). Lambing time was distributed randomly for GG, HG, MG and MHG ewes, but HMG ewes mostly lambed at night (66.67%). Labor time of HMG ewes was significantly shorter than other breeds (P0.05) and was not affected by birth weight, birth type and neither by parity. The ewes generally lambed in lay down position. After lambing, ewe normally stood up and cleaned the lamb immediately. The cleaning generally begin from the head progressed down to the whole body. The success for lamb to stand up was not significantly different among breeds. Key Words: Lambing Behavior, Garut, Crossbreeding, St. Croix, Moulton Charollai
Animal Production (Poultry, Cattle and Goat-Sheep) in Indonesia: Prospects and Strategic Development
Full text linkAnimal production in Indonesia has a remarkably good prospect, as the demand for animal products always increases in line with the increase in human population and national economic development . The high animal industry bargaining status heavily depends upon certain input factors e .g . feed availability, breeding, animal management and health, including innovative technology and other external factors . The approach to improve bargaining position of the animal industry should be carried out under simultaneous approaches within harmonized implementation of support policies at the inter-ministerial level . This should be in line with other internal implementing factors i .e . production efficiency, improved product quality, continuity of supply, and market demand. The prime animal industry profiles suggest that poultry, cattle and sheep/goat industries are prospective if their production management follows the accepted procedures and rules . To respond the developing notion of the livestock sector in Indonesia, there is a heavy need for investment support of the government, farmers/people, and private sector. The policy is the creation of a condusive investment sphere, that is expected to create employment opportunities through raising animals at the input through the marketing subsystems, hence, the development of animal production in Indonesia could answer the heavy threats faced in meeting food security, employment opportunity, people's welfare, creating devisa and national economy . Key words: Animal production, investment, prospec
