Effect of complete rumen modifier (CRM) and Calliandra calothyrus on productivity and enteric methane productions of PE dairy goat

Methanogenesis in the rumen is thought to represent 2-12% loss of energy intake. The energy loss as methane can decrease animal productivity and feed efficiency. In addition, methane is potentially involves in global warming that affects the atmosphere adversely. A research to improve PE dairy goat productivity and reduce enteric methane emission by supplementation of calliandra and complete rumen modifier (CRM) was conducted for 6 months. In this experiment 20 PE dairy goats were divided into five blocks according to body weight. The experimental design used was a randomized block design that consisted of four treatments, A). Elephant grass 50% + concentrate 50% (control), B). Elephant grass 40% + concentrate 40% + calliandra 20%, C). Elephant grass 50% + concentrate 48% + CRM 2% and D). Elephant grass 40% + concentrate 38% + calliandra 20% + CRM 2%. Data were analyzed statistically using ANOVA and Duncan test. The result showed that calliandra and CRM did not affect nutrient consumption, except that protein consumption increased (P 0.05) in calliandra treatments     (B and D). Nutrient digestibility increased in CRM (C) treatment, while other treatments did not differ from control. CRM also increased total bacteria (36.84%), milk production (67.21%), milk fat (25.0%), and reduced enteric methane production (65.71%). The improvement of milk production in CRM treatment (C) was followed by better feed efficiency than other treatments. In conclusion, CRM was more effective than calliandra in improving milk production of PE dairy goats and reduced enteric methane emission, but its effectivity was reduced in combination with calliandra.

The Effect of Zingiber Officinale Rosc in The Diets of Performance in Culled Layer Ducks

The experiment was design using a completely randomized block design (CRBD) with four treatments. Treatment were diets without Zingiber officinale rosc (A), diets contain 2,91% Zingiber officinale Rosc  (B), diets contain 5,66%. Zingiber officinale Rosc (C), and diets contain 8,26% Zingiber officinale Rosc (D). Each treatment with five replicates, and each replicate consist four culled layer ducks. Variable observed were feed conversation ratio, carcass physical composition, and meat quality. It was concluded that present  Zingiber officinale Rosc in the diets could be improved of performance in culled layer ducks.   Keywords : Zingiber officinale Rosc, Culled layer ducks, and  meat quali

PEMANFAATAN PROBIOTIK DALAM PEMBUATAN RANSUM UNTUK MENINGKATKAN EFISIENSI PENGGUNAAN RANSUM PADA TERNAK NON RUMINANSIA DI DESA MEDAHAN GIANYYAR

This activity on the service to people in Medahan Village, Blahbatuh Sub District, Gianyar District Aimed to improveded soft skill of farmers in applied of probiotic matter used and feed formulation for improveded of feed convertion for to increased of feed conversion on ruminant animal on Week, 7th October 2007 with following twenty fife farmers. The method of were lecture and training about applied probiotic matter and feed formation for non ruminant animal. Evaluated method to do on praction phase, action phase, and understand to realize phase. The result of the activity showed that praction phas eto get people response was 75 percentage, people response on action phase about applied of proiotic matter and feed formulation for non ruminant animal were 85% on understand phase that with lecture and apply about its happened undestand response to increased from 50 until 80 pecentage. It was concluded that the response of farmres to applied of probiotic matter used and feed formation for improveded of feed conversion for to increased of feed conversion on non ruminant animal were higher (70-85 percentage). </div
