Abstract

The objective of this research was to study the effects of different energy and protein ratio towards sheep’s nutrient intake and digestibility. Twenty four male sheep’s, 6 – 7 months old with initial average live weight 13+1.56 kg, coefficient variant11.78%) were used in this research. The complete feed ration which consisted of King Grass (Pennisetum purpureum), soybean powder, rice bran, dried cassava and molasses was used in this research. Protein content on each component was 10, 12 and 14% and total digestible nutrients (TDN) 60 and 65%, respectively. Dry matter (DM) and organic matter (OM) intake, DM and OM digestibility were studied in this research. Analysis of variance (ANOVA) was employed to analyze the data. Test of Small Difference (P<0.05) was then carried out if significant different occurred. The research results showed that Dry matter and OM ration intake showed significant different among treatments (P<0.05). The highest DM intake was obtained at crude protein (CP) 14% and TDN 65% i.e. 695.54 g while the lowest value was CP 14% and TDN 65% i.e. 462.11 g. Thus different DM and OM intake were caused by different ration ingredients composition. Dry matter and OM ration digestibility were not show different (P>0.05) among crude protein and TDN treatments. Different energy and protein ration treatments caused different DM and OM intake but were not cause different in DM and OM digestibility. Based on the research results, a study on the effects of different ration’s energy and protein ratio towards N efficiency should be conducted in order to increase cattle productivity.

Abstract

In broad perspective, meat contains many essential nutrients such as protein, fat, minerals, carbohydrates (minor amount) and water. The existence of these nutrients render meat not only as a nutritious food, but also potential as a media for bacterial growth, so that it needs to be further processed. One of the methods to process meat is by soaking the meat in a marinade solution (marination). There are three treatments that maybe performed on meat in the marination system. The first method is using phosphate salt solution to enhance the water holding capacity. The second method is utilizing the acidic salt solution or organic acids to soften the meat and control the bacteria growth. The third method is using spicy solution that can be combined with sugar, salt (NaCl) and organic acids to improve the physical performance and taste of meat as well as to control the growth of bacteria. It is concluded that marination of meat could increase physical, chemical, microbiological properties and sensory. Key words: Marination, meat, safety

Abstract

The present study was aimed to evaluate the use of ‘Lumpur-bahinol’ (sludge of alcohol industry) as feed for sheep on feed intake, daily gain, and feed conversion ratio. Twelve indigenous rams grouped into three consist of four were used in this study following Completely Randomized Design. Those rams were 8-10 months old, and average weight at 17,15 kg. The rams were raised in individual barn and were fed Napier grass ad libitum and commercial concentrate feed at 2% of body weight. The treatments were substitution of concentrate feed with ‘lumpur-bahinol’ in the rations at various level as follow, K5L0 (concentrate 2% BW+lumpur-bahinol 0% BW), K4L1 (Concentrate 1.6% BW+Lumpur-bahinol 0.4% BW) and K3L2 (concentrate 1.2% BW+Lumpur-bahinol 0.8% BW). These rations were adjusted to fulfill dry matter requirement at 4% BW. The result showed that inclusion of lumpur-bahinol in the ration tend to decrease total DMI (P=0.1105), being 815 and 809 g/d for K4L1 and K3L2m, respectively, compared to K5L0 (890 g/d). Similar tendency was observed in crude protein intake (P=0.1105), being 104,94 dan 92 g/d for K5L0, K4L1 and K3L2, respectively, as well as in gross energy intake (P=0.0999), being 13.3; 11.4 and 10.5 Mj/d, for K5L0, K4L1 and K3L2, respectively. This phenomena was in contrast with the digestibility that tend to increase (P=0.1056) as much as 0.96% (K4L1) and 2.80% (K3L2), respectively, compared to K5L0 (62.97%). Despite of feed intake tended to decrease as increasing lumpur-bahinol in concentrate, but the daily gain tend to be higher (P=0.1171) in K4L1 (65 g/d) and K3L2 (56 g/d) compared to K5L0 (53 g/d). Similar tendency was shown in feed conversion of K4L1 (12.5) and K3L2 (14.5) that better than of K5L0 (16.8). The conclusion of this study was lumpur-bahinol could be used to compose concentrate feeding up to 0.8% of body weight.

Abstract

A study on eating behavior of Ongole Crossbred (OC) and Limousin Crossbred (LC) steers (aged 9 months) fed fermented rice straw and concentrate has been carried out. Rice straw and concentrate were given in 60:40 ratio. Rice straw was fermented by commercial starter (BioP 2000 Z), while concentrate was composed of commercial concentrate and soybean pulp (by-product of soy-sauce industry). The diet was set to meet the dry matter (DM) requirement at 3.0% of liveweight. Eating behaviour was measured from 3 days continuously observation. Chewing number was accounted by halter equipped with tape-switch in jaw side and was recorded every 1/10 second in connected PC. The results showed that DMI of both OC (3.21 kg) and LC (4.18 kg) was similar, being 2.8% LW. However, chewing number of OC (133808 chews/d) was higher than that of LC (106353 chews/d). Chewing for eating and for rumination in OC (86995 and 46813 chews) was higher than of LC (67628 and 38725 chews). Chewing efficiency for eating in OC (0.041 g DMI/chew) was lower than that of LC (0.066 g DMI/chew). Similar tendency was observed in chewing efficiency for rumination that OC (0.080 g DMI/chew) was lower than that of LC (0.109 g DMI/chew). The conclusion is LC has a better chewing efficiency than of OC and it was pointed to different jaw size between OC and LC.   Key words: Chewing, Ongole, Limousin
