Development of Beef Cattle Innovation through “Field Laboratory” Approach

Economic growth in rural areas can be achieved by increasing the productivity of agricultural businesses. Beef cattle breeding farm is managed by small holder farmers with limited ownership integrated with other agricultural activities. This paper aims to provide information on developing beef cattle innovation at farm level through field laboratory (FL) approach or demonstration plot and direct participation with farmers. The development of cattle farming innovation at farm level is limited, hence it is needed to improve the competitiveness of agricultural businesses. Field laboratory is a model for accelerating technology transfer to farmers. The introduction of innovation in beef cattle through LL can be adopted by farmers resulted in increasing the productivity of beef cattle and added value of livestock businesses. For sustainability of technological application it is required supporting facilities and infrastructure such as institutional that provide production and marketing facilities

Responses of two genotypes of lambs on the infection of Haemonchus contortus and the level of energy supplements

A study was conducted to evaluate the responses of lambs on the infection of Haemonchus contortus and the level of energy supplements. Forty eight male lambs, 3-4 months old were used in a factorial experimental design (2x2x2) which lasted for 9 weeks. The factors were breed (Local Sumatra and Sungai Putih: 50% Local Sumatra, 25% St. Croix; 25% Barbados Blackbelly), level of Haemonchus infection (3,000 L3 and 1,500 L3 per week) and level of energy supplement (2,900 kcal/kg DM and 2,300 kcal/kg DM). Infection at 3,000 L3 decreased (P<0.05) ADG of lambs of both energy levels. An extremely low ADG (10-16 g) was observed in 3000 L3 group given low energy level. Body condition of lambs fed high energy level was constant over the experiment, but it decreased at the rate of 0.9 to 1.1 unit at the low energy supplement. EPG was higher (P>0.001) in the 3000 L3 group, was lower (P<0.05) in the Local Sumatra, but not affected (P>0.10) by energy level. PCV was not affected (P>0.10) by infection levels, but lower (P<0.01) in the low energy group or in the St Croix crosses. Eosinophil and serum protein concentration were not affected by energy and infection level, but they were higher (P<0.01) in the local Sumatra. It was concluded that strong effects of level of infection and genotype was detected to influence the impact of Haemonchus infection in lambs. However, the effect of energy levels was less consistent as judged from the EPG, PCV, eosinophil and serum protein data.   Key words : Energy level, genotype, infection level, Haemonchus contortus, lamb

Genetic and Environmental Interaction for Small Ruminant Development to Improve the Economic Value

Small ruminants contribute very significantly to farmers' income in Indonesia. The productivity of small ruminants is affected by breed or genotype and by the environment. This paper discussed the effects of genetic factors and their interaction on the economic value of goat and sheep production. Research results have shown that livestock productivity is influenced by the management system (intensive and semi-intensive) as well as by season of birth. Level of infestation by internal parasites varies according to breed, sex, a group of birth and type of birth, and rearing. Generally, worm infestation in small ruminants fed on native pasture in the rainy season is higher than in the dry season. Choosing livestock suitable and adaptable with the environment is a recommended strategy to optimize livestock productivity, hence, increase farmers’ income and welfare

The Reproductive Performance of Dairy Cattle in Smallholder Farmers

The reproductive performance of dairy cattle can be determined by the level of reproductive efficiency. This activity aims to obtain information on the reproductive performance of dairy cattle in 5 dairy cooperation unit (KUD) locations (Bogor, Cisarua, Cianjur, Garut and Pangalengan), conducted in January 2018 - May 2019. Data was collected through direct observation in the field and information from farmers. The parameters observed were: Body Weight (BW), Body Condition Score (BCS), parity, Calving Interval (CI), Sevice per Conception (S/C), Age of first calving (AFC). Data were analyzed with the GLM model from SAS (2004). The mean BW of cattle showed a difference between KUD (P 0.05), the highest was in Pangalengan (502.36 ± 5.96 kg) and the lowest was in Cisarua (415.19 ± 9.21 kg). The total BCS of KUD was 2.76 ± 0.30. The mean overall age of KUD was 56.20 ± 25.71 months, varying based on KUD location (P 0.05). The mean parity of all KUDs was 2.87 ± 1.65. The overall AFC average for KUD was 26.80 ± 2.27 months, differently based on the lowest KUD in Bogor and the highest in Cisarua. The mean CI in this study was still quite good, around 13.14 ± 1.73 months. The highest CI was in Bogor (13.53±0.17 months), while the lowest was in Garut (12.04 months). The overall average S/C of KUD was 1.25 ± 0.30. The S/C in KUD Cianjur was higher than in the other 4 KUDs. The reproductive performance of cows in overall KUD farmers is still in good condition. The existence of differences in the reproductive performance of cows between locations may be differences in mating management

Performances of the first and second generation composite breed resulting from crossing between local Sumatra sheep and hair sheep.

Improving sheep productivity can be conducted by genetic improvement and improving environmental factors. Genetic improvement usually can be done by selection and creating composite or synthetic breed by crossbreeding. Composite breed created by crossbreeding between different breeds and followed by selection. The study of crossing between Sumatra sheep with fat-tail sheep from East Java, St . Croix hair sheep (US) and Barbados Blackbelly hair sheep has been carried out since 1986, and show that the crossbred are better in term of production and reproduction . In 1996/1997, the first generation (F1) of composite breed (KOM) has been created by crossing between Barbados Cross (BC) rams and St . Croix Cross (HC) ewes or reciprocally. The second generation (F2) of composite breed has been created by inter-se mating . However, F1-KOM and F2-KOM vary in their performances, therefore selection should be conducted. The results showed that birth weight and weaning weight of crossing between BC rams and HC ewes tended to be heavier than those of reciprocal crossing between HC rams and BC ewes, but the differences were not significant (P>0 .05) . Birth weight and weaning weight of crossing between BC rams with HC ewes and reciprocal cross were 2.48 _+ 0.70 kg (n=791), 12 .50 _+ 3 .26 kg (n=640) and 2.37 _+ 0.62 kg (n=147), 12 .29 _+ 3.30kg (n=122), respectively . Meanwhile, observations of inter-se mating of Fl-KOM showed that the weight at the first mating was 26 .7 _+ 3.82 kg (n=80), age of dam at the first lambing was 15 .7 _+ 1 .73 months (n=83), weight at post-partum was 29 .86 _+ 3 .30 kg, and litter size at the first parity was 1 .43 _+ 0.59 (n=83) . The mean of age at the first mating of KOM was around 10 .7 months. Mean of mating weight at the second parity was 28 .29 +_ 3 .51 kg (n=11), age of dam at the second lambing was 20.6 _+ 1 .99 month (n=11), post-partum weight was 26 .92 _+ 4.03 kg (n=11) and litter size was 1 .64 _+ 0.81 (n=11) . Weaning weight of Fl-KOM, F2-KOM, BC, HC and St. Croix (H) after adjusted by season, sex, age of dam and type of birth were significantly different among Fl-KOM with F2-KOM, BC, HC, and H. However, there were no significantly different among F2-KOM with BC and HC. The results of the study indicated that for improving selection respons, the corrections or adjustments of environmentally induced superiority (sex, type of birth and age of dam at lambing) for every genotype and certain generation should be conducted, in order to increase the rate of genetic improvement

Weaning weight of Fl-KOM, F2-KOM, BC, HC and St. Croix (H) after adjusted by season, sex, age of dam and type of birth were significantly different among Fl-KOM with F2-KOM, BC, HC, and H. However, there were no significantly different among F2-KOM with BC and HC. The results of the study indicated that for improving selection respons, the corrections or adjustments of environmentally induced superiority (sex, type of birth and age of dam at lambing) for every genotype and certain generation should be conducted, in order to increase the rate of genetic improvement.   Key words : Composite breed, first generation, second generatio
