This study aimed to evaluate feed protein utilization and nitrogen emission of young and mature Kejobong goats fed different concentrations of concentrate and forage. Sixteen heads of male Kejobong goats consisted of eight heads young goats (5 months old) and eight heads mature goats (9 months old) with initial body weight (BW) of 14 ± 1.46 kg, and 22.3 ± 1.99 kg, respectively were arranged in a nested design. All goats were fed with two different rations of concentrate and forage (C30 = 30% concentrate: 70% forage and C70 = 70% concentrate: 30% forage). The data were analyzed using ANOVA procedure. This study showed that the average daily gain (ADG) did not differ (p>0.05) in both ages, but it differed (p<0.05) in concentrate levels. The ADG of goats fed C70 was significantly higher (p<0.05) than those of goats fed C30 in both ages. The digestible crude protein (DCP) of young and mature goats was similar (p>0.05), while there was a significantly difference (p<0.05) between the treatments. There were no effects of different ages of goats and concentrate levels on feed conversion ratio (FCR) (p>0.05). The different ages of goats and concentrate levels affected N retention (g/day) and total N2O emission (g/day). It was concluded that ADG, DCP and FCR did not differ in mature and young Kejobong goats, while young goats had less N2O emissions than mature goats. Goats fed 70% of concentrate improved their ADG, DCP, N retention (g/day) and produced less N2O emission.

This research has been done during August 2004 - January 2005 at Laboratorium Ilmu Ternak Potong dan Kerja, Fakultas Peternakan Universitas Diponegoro Semarang. The study was set up to investigate the performance of ongole crossbred and Friesian Holstein crossbred young bulls fed concentrate and Napier grass hay. This research used 4 yearling ongole crossbred (PO) bulls with the initial body weight: 228,17 + 14,77 kg (CV = 6,47%) and 4 yearling friesian holstein crossbred (PFH) bulls with the body weight: 196,34 + 7,64 kg (CV = 3,89%). The Independent Sample Comparisons was used in this study. Those bulls were fed 30% hay of Napier grass and 70% concentrate made of “bungkil kelapa sawit” (80%) and rice bran (20%). The ration was given based on dry matter need, 2.5% of the body weight. Parameters observed were the average daily gain (ADG), feed intake (dry matter intake, crude protein intake, Total Digestible Nutrients’ 2 Sains Peternakan Vol.8 (1), Maret 2010 intake) and feed conversion. Data were analyzed using t-test; except for feed conversion was analyzed deskriptifely.The result indicated that those cattle fed concentrate and Napier grass had ADG and feed intake relatively similar. The average of ADG PO bulls were 0.21 kg and PFH bulls were 0.22 kg. Dry matter intakes of PO and PFH bulls were 3.33 kg/day and 2.83 kg/day. Crude protein intake of PO bulls were 0,45 kg/day and that of PFH bulls were 0,38 kg/day, whereas TDN intake of PO bulls were 1,93 kg/day and PFH bulls were 1,20 kg/day. Feed conversion of PO bulls was 15.86 and that of PFH bulls was 12.86. It can be concluded that the performance of Ongole crossbred and Friesian Holstein crossbred young bulls fed concentrate and Napier grass hay was similar. Those indicated that PFH bulls had productivity that was the same as PO bulls. Key words : Bulls, performance, feed intake, feed conversion

Penelitian ini bertujuan untuk mengetahui pengaruh pemanfaatan tepung daun kelor (Moringa oleifera) dalam ransum terhadap produksi non karkas kelinci New Zealand White jantan. Perlakuan yang diberikan yaitu R1 = ransum tanpa tepung daun kelor dan R2 = ransum dengan kandungan tepung daun kelor 10%. Hasil penelitian menunjukkan bahwa produksi non karkas tidak berbeda nyata (P>0,05) antar perlakuan pakan. Rata-rata bobot dan persentase non karkas 1.072,91 g dan 42,87%, bobot dan persentase kepala 238,81 g dan 22,27%, bobot dan persentase darah 66,59 g dan 6,21%, bobot dan persentase ekor 13,46 g dan 1,26%, bobot dan persentase kulit 250,30 g dan 23,22%, bobot dan persentase kaki 62,50 g dan 5,83% serta bobot dan persentase visera netto 234,23 g dan 21,80%. Simpulan penelitian ini adalah bahwa pemberian tepung daun kelor dan tanpa daun kelor memberikan hasil yang relatif sama terhadap produksi non karkas kelinci New Zealand White jantan.

Objective: The aim of this study were to evaluate the inclusion of Indigofera leaf meal (ILM) in the ration on the carcass and non-carcass production, meat chemical composition and feces-derived methane yield of New Zealand White (NZW) rabbits.Methods: Twenty eights male NZW rabbits with initial body weight of 1455.25 ± 142.41 g, and 65-70 d old were used in this study. There were four treatments namely basal feed (T0); inclusion 4% (T1); 8% (T2), and 12% of ILM (T3) in the ration. The ration was made in form of pellet, and iso-protein that containing 16% of crude protein (CP). The observed variables were carcass and non-carcass production, meat nutrient content and feces-derived methane production.Results: The study result showed that inclusion of ILM in the rabbit ration up to 12% gave no significant effect (P>0.05) on the carcass and non-carcass production, nutrient content of the rabbit meat (CP, extract ether, moisture and ash) both in Longissimus dorsi (LD) and Bicep femoris (BF) muscles. The moisture concentration in LD muscle showed lower than that in BF muscle, while EE content of LD was higher than that in BF muscle. The result also showed that the incorporation of ILM in the ration up to 12% gave no significant effect (P>0.05) on the methane production of rabbit feces.Conclusions: The treatments gave no impact on the observed variables. Therefore, ILM can be used as a protein source in male growing rabbit ration at least up to 12%.

Central Java Province is one of the provinces with the potential to be a source of beef cattle. The increase in the beef cattle population in Central Java province is expected to increase the national beef cattle population significantly. This study aims to assess the potential of beef cattle and develop a strategy for its development in the Province of Central Java. A study was done using the survey method, and secondary data were obtained from related agencies. Samples were taken using the stratified proportional method as many as 112 farmers. Data were analyzed using LQ analysis, trend analysis, and SWOT analysis. LQ analysis showed that beef cattle's potential base area was in the Grobogan Regency and Kendal Regency. Estimation of beef cattle population in Central Java Province based on trend analysis shows that the areas of Salatiga City, Demak Regency and Grobogan Regency have the potential to become beef cattle base areas. Based on the carrying capacity, areas that can potentially increase livestock populations are Semarang Regency, Salatiga City, and Grobogan Regency. The results of the SWOT analysis show that the right strategy in developing beef cattle is in quadrant I, namely supporting the growth of an aggressive strategy that uses strength to gain opportunities. The recommendation that can be given from this study is that the implementation of strategies in each region will differ according to the potential of each region.

The evaluation of Carica seed supplementation in feed was carried out to assess its effect on sheep body composition such as water, fat, and protein, using the urea space method which is one method of determining the body composition of livestock without cutting. The study involved 15 male thin-tailed sheep aged 3 months with an average initial body weight of 10.68±1.28 kg, using a completely randomized design (CRD) with three treatments: 5% (T1), 12.5% (T2), and 20% (T3) carica seed supplementation, with five replicates each. The observed parameters included feed intake, daily weight gain, as well as water, fat, and protein content in the body. ANOVA analysis at a 5% significance level revealed that different concentrations of Carica seed significantly affected (P<0.05) crude protein intake, daily weight gain, and body protein composition at week 11. The sheep in the T3 treatment showed the crude protein consumption and daily body weight gain as well as a significant increase in body protein composition compared to the other treatments. Overall, Carica seed supplementation led to a significant increase in body protein content, while having no significant effect on body fat and water composition.
