Abstract

This research had been conducted to obtain a feed formula that is capable of supporting optimal production performance  both in broilers and laying hens fed on feed containing fermented jatropha seed meal and addition saccarides. Fifty four broiler and fifty four layer were used.  Nested classification was the experimental design with bird kinds as group, levels of fermented Jatropha curcas meal (JCM-F) (9%, 12%, 15%) as  sub group and  levels of fructooligosaccharida/FOS (0.5%; 1%; 1.5%) as a sub sub group.  There were 3  replications in each treatment. Jatropha curcas meal was fermented with lactid acid bacteria (L. acidophilus and Bifidobacter spp) for 12 x 24 hour in 37oC.  The objective of the research was to evaluate growth, feed consumption, nutrient digestibility (crude protein and gross energy), blood metabolites  (glucose, cholesterol and trgliseride).  The results showed that the type of chicken had significant effect on growth and protein retention. The level of Jatropha curcas meal had significant effect on blood  serum triglyseride concentration.  On the other hand, the level of FOS had no significant effect on all variables. It could be concluded that Jatropha curcas meal  is better as broiler feed than layer feed with 0.5% FOS. However, to be used as feed of laying hens, it requires further optimalization of the fermentation process. Animal Production 15(2):98-105, May 2013

Abstract

Abstract. The purpose of this research was to determine the effect of the use of Natuzyme in feed containing non-starch polysaccharides on the quality of chicken meat. Materials used were 71 native hens of 18 week-old. The experiment was conducted using Completely Randomized Design (CRD), 3 x 3 factorial pattern. Each treatment was repeated three times and was tested further with Duncan t test. The first treatment was the use of non-starch polysaccharides (R) with the levels of 0, 5 and 10%. The second treatment was the use of Natuzyme (S) with the levels of 0, 0.1 and 0.2%. The variables measured were: energy consumption, fat consumption, carcass weight, meat glycogen, meat fat, and cholesterol of meat. The results showed that the treatments did not significantly affect energy consumption, fat consumption, carcass weight and fat content of meat. The use of non-starch polysaccharides did not significantly affect the levels of meat glycogen, while the use of Natuzyme significantly affected the levels of meat cholesterol. The conclusion is that the Natuzyme only works on feedstuffs, not in the chicken digestive tract. The sources of non-starch polysaccharide in feedstuffs can be used as an energy source for chickens until a level of 10%.Key Words: Natuzyme, non-starch polysaccharides, meat quality

Abstract

An experiment was conducted to investigate the effect of soybean hulls levels substitution in to corn as ration in twenty seven rams. The animal had a mean of live weight of 12.86 ± 1.94 kg. Levels of substitution were 0, 50, and 100% or 0, 25, and 50% ration dry matter basis and rations were iso-nitrogeneous. Analysis of variance were conducted for completely randomized design and polynomial orthogonal test were applied for the statistical analysis. Inclusion of soybean hulls in 50% ration dry matter had no effect on daily gain (99.71 ± 22.97 g), and digestible crude protein (62.43 ± 6.56 %). However, dry matter consumption tended to increase linearly and as soybean hulls level increase in the ration (P<0.01). The digestible energy significantly decrease linearly (P<0.01), whereas intake of the energy had same was 1.27 ± 0.33, 1.44 ± 0.17, and 1.23 ± 0.19 Mcal/day for ration containing 0, 25, 50% of soybean hulls, respectively. It was concluded that the soybean hulls may be substituted for corn. (Animal Production 2(2): 98-103 (2000) Key words : soybean hulls, corn, digestibility, daily gain.

Abstract

Thirtysix native hens were used to determine the effect of adding Sodium-Potassium and Calcium-Magnesium to the diet of Native Chicken hens on determination of native chick sexes. Fifteen hens (n=5; control, Na-K and Ca-Mg) were fed for 1 month and the other hens (n=6, for control, Na-K and Ca-Mg) were fed for two months, then  all hens were artificially inseminated, intra-vaginally, dose of 100 million perm cell per 0.1 ml, once a week for two weeks. On day 2 of insemination, all eggs were collected and evaluated daily for 14 days.  Every 5 days, the selected eggs were incubated for 7 days and followed by candling to assess fertility.  On day 21-22 of incubation, day old chicks were evaluated using vent sexing method to assess the sex ratio. Type of nutrition, fed at both for 1 month and two months had a similar results in fertility, hatchability and chick sex ratio:  62.79, 58.03, 59.52;  52.02, 50.93, 55.54 and 46.11, 51.89, 46.67 percent, respectively.  Feeding period of three type of diet value for fertility, hatchability and sex ratio is 59.19, 61.04; 53.61, 52.05, and 48.24, 47.86, respectively.  Our results suggest that different amount of ions in the diet of hens could not have a significant effect on the percent fertility, hatchability and sex ratio of chicks.

Abstract

Abstract. Menhaden fish oil is commonly used as chicken feed mixture as cheap omega-3 source, plenty and available over the year. Chicken feed containing menhaden fish oil can affect digestion, metabolism and production of meat and egg. The research aimed to evaluate lipid biosynthesis on blood and egg yolk of local chicken fed with feed containing menhaden fish oil as an omega-3 source. The research used 60 hens placed in individual battery cages with four treatments and five repetitions. The treatments were R0 = control/without menhaden fish oil as omega-3 source; R1 = with 2.5%; R2= with 5.0% and R3 = with 7.5% menhaden fish oils respectively. Data analysis used analysis of variance continued with Duncan’s test. The result of the researh showed that the treatments did not signifcantly affect lipid consumption, blood lipid content, blood and yolk cholesterols. However, the treatment significantly affected yolk lipid. The used of menhaden fish oil in feed as an omega-3 source was accumulated in yolk eggs as followed: C18:3 from 0.17% (R0) to 0.29% (R2); DHA (C22:6) from 0.87% (R0) to 3.12% (R3); EPA C18:2 from 1.05% (R0) to 1.85% (R2); EPA C22:4 from 0.77% (R0) to 0.88% (R2) respectively. It could be concluded that enhancement of omega-3 content in egg could be achieved through addition of omega-3 sources in feed.Keywords: egg quality, lipid profile, menhaden fish oilAnimal Production 14(1):6-12, January 2012
