Abstract

Although Etawah Crossbred (PE) goat is considered to be dual purpose (meat and milk) goat, it is mainly raised for meat production. Since early 1990, there has been a growing interest of the farmer in some places to raise PE goat for milk production without sacrificing its role to produce kids for meat. The average birth weight of PE kids varied widely (2.8 – 5 kg), resulted in a high variation in weaning weight (9 – 14 kg). A high pre-weaning mortality of 10 – 50% was a major source of lost in goat production in Indonesia, partly due to low birth weight and/or miss mothering ability. Young female PE goat reached puberty at 8 – 12 months of age and at body weight of about 18 – 22 kg or about 53 – 60% of mature body weight. Gestation length varied between 142 – 156 days, and first post partum estrous occurred at 3 – 5 months after parturition took place, resulted in 8 – 10 months of kidding intervals. Lactation period lasted for 5 – 8 months with total milk yield of 177 – 203 kg/lactation (average 0.85 kg/day). Although milk yield of PE goat was not as high as milk yield of some other dairy goats, the ability of PE goat to cope with harsh local environment, particularly climate and feed conditions, was an advantage. Therefore, raising PE goat would still be an important part of farmer activities in the rural areas in Indonesia.  Key words: PE goat, reproduction, milk production

Abstract

This paper is aimed to review the development of genetic evaluation on dairy cattle based on milk production, including recording system, mathematical model of the milk curve, genetic parameters, and genetic model for predicting breeding values. Test day is the best system to record milk yield as it can be used to predict lactation curve and genetic parameters. Ali-Schaeffer curve was the best curve to estimate milk yield (r > 0.99). Fixed and random regression models have been widely used to give more advantages in breeding program. The models are able to analyse the records measured at different stage of lactation, and  to predict a total breeding value from incomplete and part records. For practically used, fixed regression model (MRT) is suggested because it does not have numerical problem and is easier to be used.   Key words: Dairy cattle, breeding value, test day, random regression, fixed regression

Abstract

The productivity of local goat is still relatively lower compared to that of other breed for sub-tropic area. Efforts for increasing its productivity through crossbreeding with genotypes goat could be approached by technological application of artificial insemination (AI). In supporting this technology, the viability of semen for both quality and quantity is needed. Evaluation of Indonesian goat semen characterisation shows a potency for frozen semen. The survive ability of sperm in fresh semen is very limited therefore reducing the temperature to -5°C (chilled semen) or -196°C (frozen semen) could be done to maintain its survive ability. Optimalization of frozen semen could be done by diluting in Tris extender with 6% glycerol, equilibrating for 4 hours and cooling for 4 – 5 minutes above surface of LN2 before stored in LN2 (-196°C). Thawing at > 7°C for 30 seconds resulted in the highest percentage of mortility (52.0%) and survivability (65.03%). Chilled semen is the best alternative for artificial insemination (AI) in the field condition where the supply of container and liquid nitrogen are limited. The survivability of chilled semen could be maintained for 8 days and the highest percentage of pregnancy resulted from chilled semen stored up to 24 – 48 hours.  Key words : Goat, semen quality, frozen semen, chilled semen, artificial insemination

Abstract

Nitrogen (N) is one of the major limiting factors for crop growth and is required in adequate amount, due to its function as protein and enzyme components. In general, plants need sufficient nitrogen supply at all levels of growth, especially at the beginning of growth phase. Therefore, the availability of less expensive N resources would reduce the production cost. The increasing  use  of  chemical  fertilizer  would  probably  disturb  soil  microorganisms,  reduce  the  physical  and  chemical characteristics of soil because not all of N based fertilizer applied can be absorbed by the plants. Approximately only 50% can be used by crops, while the rest will be altered by microorganism into unavailable N for crops or else dissappear in the form of gas. Leguminous crops have the capacity to immobilize N2  and convert into the available N if innoculated with Rhizobium. The amount of N2 fixed varies depending on legume species and their environment.   Key words: Nitrogen fixation, legume

Abstract

Feed supply is getting limited since the use of land for forages has been replaced by building industries big plantation, agriculture. Sustainable integration between animal and food crop and plantation is efficient and gives advantage for both. Rice, cassava soybean, groundnut, palm oil, coconut, coffee, cocoa and sugar cane are food crop and plantation which their byproducts are generally  used or modified/processed for ruminant production. This paper describes optimization on the use of these byproducts to decrease feed cost without ignoring the feed quality. These byproducts have special characteristic and limitation with fluctuated price. Their nutritive values vary and they can be grouped into fiber, fiber-energy, fiber-protein, protein or energy sources. Therefore, special strategy for each location and purpose of livestock industry is required to get an efficient and optimal feed composition.   Key words: Feed, agriculture byproduct, beef cattle

Abstract

Cattle and maize play important roles in the dryland faming systems in Timor island of East Nusa Tenggara province, contributing  to  the  farmers’  income,  social  status,  and  the  regional  food  security  and  sources  of  income.  However,  the productivity of both commodities is low because of several problems. Lack of feed supply and management knowledge has contributed to the low cattle productivity, while lack of cultivation knowledge and the use of low productivity local maize have caused low productivity in maize. Farmers in Timor in general do not apply fertilizer to their maize plants, although lack of nitrogen (N) is evident in many of their maize fields. There is potential to improve the available N in the soils through the incorporation of herbaceous legumes, which can supply the nutrient to the soil as well as providing good quality fodders for the cattle. Among the introduced herbaceous legumes tested, Clitoria ternatea (butterfly pea) has shown good performances to be used as an alternative herbaceous legume in the farming system for improving soil fertility and maize production as well as to provide good quality fordder for the cattle.   Key words: Crop Livestock System, herbaceous legumes, Clitoria ternatea, Timor, nitrogen fixation, maize
