Keluaran Kreatinin Pada Domba Lokal Jantan Akibat Pemberian Pakan Siang Dan Malam Hari (Creatinine Excretionin Indigenous Ramswith Day and Night Feeding)

Aim of study wasto determinethe amount ofcreatininein indigenousrams under day and night feeding. The materialsusedinthis study were 11 indigenousrams of 1 year old, average weighing 24.12+2.54kg(CV=10.53%). They were fed completefeed in form of pellet, containing crude protein (CP) 12.01% and total digestible nutrients (TDN) 66.73%. This study used a completely randomized design (CRD) with 3 treatments and unequal replications. The treatments applied were time of feeding,namely: day time feeding (T1); night time feeding (T2); and day and night time feeding. Parameters measured were dry matter intake (DMI), average daily gain (ADG), and creatinine excretion. Dry matter intake, ADG and creatinine excretion of the second (fifth week) and third (ninth week) had an average number of 1,070 g/day; 95 g; 29 mg/day and 36 mg/day, respectively.However, treatment gained significantly different (P<0.05) on first creatinine excretion (second week) the creatinine excretion of T1, T2, and T3 were 39; 88; and 4 mg/day, respectively. It could be concluded that feeding during the day and night had no effect on creatinine excretionof indigenous rams

Ruminal Fermentation and Blood Glucose at Low and High Level Intake of Growing and Mature Kacang Goat

This study was conducted to compare ruminal Volatile Fatty Acids (VFA) concentration andblood glucose in young and mature Kacang goats at different feeding levels. Eigth male young Kacanggoats weights at 12.75±2.68 kg (6-7 months) and male mature goat weights at ± 17.34±3.32 kg (8-12months) were used in this study. The pelleted complete feed was formulated to give 18,8% of CrudeProtein (CP) and 78.82% of total digestible nutrients (TDN). The experiment design was nested designexperimental 2x2 with 4 replications. The main factors (based on nested) were young and mature goatsand the second factor was low feeding (near maintenance level) and high feeding (2X maintenance).Data measured were daily feed intake, feed digestibilities, ruminal VFA concentration and bloodglucose. The data obtained were analyzed by using analysis of variance. The results showed that drymatter intake (DMI), digestible carbohydrates, digestible crude fiber, and digestible organic matter wasaffected by age (P0.05). Ruminal VFA and blood glucose concentrations were found similar (P>0.05) neither in young and mature goats. However, VFA and concentration on the 3 and 6 h on high feeding aswell as blood glucose on 3 h in high feeding were higher than those on low feeding

Produktivitas Sapi Jawa yang Diberi Pakan Basal Jerami Padi dengan Berbagai Level Konsentrat

This research was conducted to evaluate the productivity of Jawa cattle which was fattened using rice straw with various levels of concentrate. Twelve heads of Jabres bulls, two years old, with the initial body weight of 270,6 ± 38,03 kg (CV=14,06%) were used in this experiment. Those Jabres bulls were fed rice straw ad libitum and different level of concentrate that consisted of rice bran, copra meal, beer waste product, and minerals. Completely Randomized Block Design with 3 treatments and 4 blocks of different body weights were used in this study. The treatments were T1= 30% concentrate of the total DM requirements, T2= 50% concentrate of the total DM requirements, T3 = 70% concentrate of the total DM requirements. The collected data were dry matter intake (DMI), protein and total digestible nutrients (TDN) intake, dry matter digestibility, the average daily gain (ADG), and feed conversion ratio (FCR). The results showed that different level of concentrate did not influence the DMI, CP and TDN intake, and also dry matter digestibility (P>0.05). The average of DMI, CP, and TDN intake were 5.69 kg, 0.78 kg, and 3,95 kg/head/day respectively. The average of dry matter digestibility was 52.94%. The ADG was 0.53 kg and FCR was 12.80. The conclusion of this research was that the productivity of Jabres cattle fattened using rice straw and 30-70% concentrate were relatively the same

Produksi Karkas Dan Non Karkas Kambing Kacang Jantan Yang Diberi Pakan Dengan Level Protein Dan Energi Berbeda (Carcass and Non-carcass Production of Male Kacang Goat Fed with Different Levels of Protein and Energy)

The product of slaughtered goat are carcass and non-carcass. One of the factors that affect carcass and non-carcass weight is the slaughter weight which is affected by the quality of the feed. This study aimed to assess the effect of different protein and energy levels of the diet to the weight of carcass and non carcass of male Kacang goat. Fifteen male Kacang goats at the age of 6 – 18 months with the initial body weight of 14.28 ± 3.36 kg (CV =23.55%) were set in a randomized block design with 3 different treatments: T1 = crude protein (CP) 9.20% and total digestible nutrients (TDN) 54.67%, T2 = CP 11.67% and TDN 58.61%, T3 = CP 18.33% and TDN 65.23%. The goat was grouped based on the initial body weight. The analysis of variance was used to analyze the data and the differences among those treatments were further tested using Duncan's Multiple Range test. The results showed that goat which was fed with different quality of feed produce slaughter weight T1 (18,516 g) was lower (P<0.05) than T2 (21,334 g), but the those were not significantly different (P>0.05) with T3 (20,036 g). Non-carcass weight of T1 (9,984 g) was lower (P<0.05) than T2 (11,384 g), but both of them were not significantly different (P>0.05) with T3 (10,648 g), whereas carcass weight was not significantly different (P>0.05) with an average of 9,290 g. The conclusion of this study was the feed of Kacang goat with CP 11.67% and TDN 58.61% yielded highest slaughter, and non- carcass weight

Korelasi Antara Bobot Badan Induk Dengan Litter Size, Bobot Lahir Dan Mortalitas Anak Kelinci New Zealand White

This study aims to determine the relationship between body weight of does with litter size, birth weight and mortality in New Zealand White (NZW) rabbits. The research was conducted at the Central Breeding and Raising Non Ruminant Livestock unit Balekambang, Surakarta, Central Java. The material used in this study was 35 does that had sexual maturity and have given birth at least once aged maximum 3 years old. In addition, the study also used 7 bucks aged approximately 2 years. Data were analysed using simple linear regression analysis. The study found that the weight of the does had a very weak correlation value to litter size, birth weight and mortality of young rabbits

Pola Pertumbuhan Kambing Jawarandu Betina Di Kabupaten Rembang (Growth Pattern of Female Jawarandu Goat in Rembang Regency)

This study was aimed to determine the growth pattern of female Jawarandu goats based on body weight and body measurements. The material used in this study was 185 heads female Jawarandu goats aged 0-4 years. Goats sampling was done by purposive sampling methods. The variables measured were body weight, shoulder height, body length and chest girth. The results showed that body weight, shoulder height, body length and chest girth have the similar growth pattern. From the age of 0-3 months to >18-30 months (2 pairs permanent incisors teeth; pit) the body measurements of goat was increased (P<0.05), while at age of >18-30 months (2 pairs pit) and >30-42 months (3 pairs pit) the body measurements was similar (P>0.05), increased again (P<0.05) from age of >30-42 months (3 pairs pit) to >42-48 months (4 pairs pit), except in shoulders height (P>0.05). The conclusion could be drawn from this study was the shoulders height, chest girth, body length and body weight in female Jawarandu goats (from the age of 0-3 months to >30-42 months (3 pairs pit) grown in similar pattern, however the chest girth, body length and body weight were increased again at the age of >42-48 months (4 pairs pit) except shoulders height
