Abstract

Zeolite is a composite minerals from mining which can be used as a source of minerals in animal ration. It has high absorbability and cation exchange characteristics. This study was aimed to examine the influence of zeolit and blood meal in the pig ration on pork quality characterictics. The experiment used 27 crossbred pig comprising 19 gilts and 8 barrows, with initial weight of 25.29 + 2.67 kgs. They were set up in a completely randomized factorial design 3 x 3, where the first factor was zeolit levels (0, 3, and 6%) and the second factor was blood meal level (0, 5, and 10%). The results showed that there were no significant influence of zeolite, blood meal or their interaction on all meat quality characteristics including pH, water holding capacity, tenderness, color and intramuscular fat contents of pork, except the measurement at pH of six hours postmortem of the pork was significantly (P < 0.01) affected by blood meal level of the ration. Five percent (5%) blood meal in the ration gave the highest pH of pork compared to the other blood meal levels. Key words: pig, pork quality, zeolite, blood meal

Abstract

Dendeng is a typical Indonesian jerked meat commonly made from sliced or ground beef with 2 mm thickness. This research was conducted to study the effect of kind of meat and leaching method on pH, toughness, protein, fat content and peroxide value (PV) of ground jerked meat. The experiment was set up in a completely randomized factorial design with three replications. The first factor was three levels of leaching methods (no washing, washed in 1.5 x 1.5 x1.5 cm size and washed minced meat). The second factor was kind of meat namely horse meat, lamb and beef. The results indicated that neither interaction effect between leaching and kind of meat nor effect of leaching were significant on all characteristics observed. Kind of meat influenced significantly on the pH, toughness, fat content and PV of dendeng (P < 0.01). Key words: dendeng, physical-chemical characteristics, leaching

Abstract

Lesser mouse deer is a native animal, which is commonly found in the forest of Java and information concerning this animal is still limited. This research explored the quality of lesser mouse deer meat (Tragulus javanicus). Eight lesser mouse deer (four females and four males) were used in quality aspects of lesser mouse deer meat. The physical properties observed were pH, water holding capacity, tenderness, and cooking loss. While the chemical properties observed were proximate analysis, amino acids, fatty acids, cholesterol, and EPA-DHA of the meat. The results showed that meat samples had average of ultimate pH (6.32), water holding capacity (32.82%), tenderness (1.80 kg f/m2), and cooking loss (45.15%). The average meat chemical compositions namely content of water, protein, fat, ash and cholesterol were 76.33%, 21.42%, 0.51%, 1.20%, and 50.00 mg/100 g, respectively. Fatty acids consisted of lauric, miristic, palmitic, stearic, oleic, linoleic, and linolenic acid were in the amount of 1.04% 3.09%, 30.97%, 0.77%, 59.41%, 3.22%, and 1.12%, respectively. The total EPA and DHA was 0.13% and 0.05%. Respectively, the results showed that quality aspects of  lesser mouse deer meat had a high ultimate pH, low water holding capacity, tenderness, high cooking loss, and high water content, high protein, low fat and high cholesterol.

Abstract

The breed patterns in growth and distribution of muscle were studied using three breeds of beef cattle entering fattening phase. This study involved 23 grass-fed steer Brahman, 24 Hereford and 22 Brahman x Hereford crosses with a live weight range of 300 to 600 kgs. An allometric Huxley model was used to study the growth and distribution patterns of muscle tissue within wholesale cut.  There were several cuts in which the muscle growth coefficients were significantly different among breeds. Comparisons of muscle weight distribution at log natural of 75 kg side muscle + bone weight (4.313 kg) generally showed significant between-breed differences. Herefords tended to have more muscles in their wholesale cuts than Brahmans and/or Brahman x Hereford crosses, except the muscles in Tenderloin, Rib Set and Chuck. Brahmans had heavier Topside and Silverside than Herefords and Brahman x Hereford crosses and the differences were maintained at log natural of 114 kg side muscle + bone weight (4.733 kg).  At this heavier weight, there was a general tendency for Brahmans to have more muscle in their wholesale cuts than the Brahman x Hereford steers, except the muscle in Loin and Neck + Sticking.

Abstract

The growth and distribution patterns of carcass fat were investigated in three breeds of beef cattle entering fattening phase. The study involved 23 grass-fed steer Brahman, 24 Hereford and 22 Brahmanx Hereford crosses with a live weight range from 300-600 kg. An allometric Huxley model was used to study the growth and distribution patterns of fat tissue within wholesale cut. In most cases, Brahmans had significantly higher growth coefficients than Herefords and/or BrahmanxHereford crosses while Herefords and BrahmanxHereford crosses had similar growth coefficients in wholesale cuts. At log natural of 75 kg side muscle+bone weight (4.313 kg), Herefords had significantly a higher fat weight within wholesale cuts than Brahmans and BrahmanxHereford crosses. Comparison at log natural of 114 kg side muscle+bone weight (4.733 kg), whilst Brahmans and Herefords were similar in fat weight distribution, the cross-bred steer had lower fat weights than the other two breed groups in almost all wholesale cuts.

Abstract

Lecithin cholesterol acyltransferase (LCAT) is a soluble enzyme that converts cholesterol and lecithin to cholesteryl esters and lysolecithins on the surface of high density lipoprotein and plays an important role in lipoprotein metabolism. The research was aimed to explore single nucleotide polymorphisms of LCAT gene in Indonesian local sheep. A total of 118 genomic DNA of Indonesian local sheep were used in this research, consisted of Sumatera Thin Tail (43 heads), Garut (19 heads), Javanese Thin Tail (17 heads), Javanese Fat Tail (6 heads), Rote Island (7 heads), Kissar (7 heads), Sumbawa (10 heads), and Lembah Palu (9 heads). Polymerase chain reaction was used to amplify genomic DNA for exon 6 (250 bp) and direct sequencing method was used to identify polymorphism sequences. The sequences were analyzed with BioEdit and MEGA 5.2 software. The BLAST sequence was obtained from Gene Bank GQ 150556.1. The results showed three novel SNPs, i.e. c.742C>T, c.770 T>A and c.882C>T. Substitution of cytosine to thymine c.742 is a synonymous mutation; thymine to adenine c.770 and cytosine to thymine c.882 are non-synonymous mutations. Polymorphisms of LCAT gene exon 6 was found in Sumatera Thin Tail, Javanese Thin Tail, Javanese Fat Tail, Garut, Lembah Palu, and Rote Island.

Abstract

An experiment was conducted to investigate the effect of formaldehyde-treated Palm Kernel Cake (BIS) in male Priangan sheep diet and its effect on animal performance, N utilization, and unsaturated fatty acids composition of musculus longisimus dorsal. The experiment was designed based on completly randomized design with four treatments and nine replications. The treatments consisted of four levels of formaldehyde treated BIS: R1 (0%), R2 (15%), R3 (30%) and R4 (45%). Results indicated that formaldehyde treated BIS up to 45% in diet did not negatively affect consumption, dry matter digestibility and daily live weight gain. Formaldehyde protection especially in R4 could significantly reduce ruminal N-NH3 concentration, increased protein digestibility and nitrogen retention, but did not influence allantoin urine concentration. Unsaturated fatty acid composition of musculus longisimus dorsal was not affected by formaldehyde treated BIS in diet. It is concluded that the inclusion of 45% formaldehyde treated BIS in diet did not negatively affect animal performance, and R4 is the most effective in improving nitrogen utilization in male Priangan sheep, but unable to alter the unsaturated fatty acids composition of musculus longisimus dorsal. Key Words: Palm Kernel Cake, Formaldehyde, Performance, Nitrogen, Unsaturated Fatty Acids
