Abstract

High environmental temperature may cause heat stress in poultry. This may increase water consumption, decrease feed intake and in turn, decrease production and triiodothyronine hormone level. The aim of the experiment was to study performance and plasma triiodothyronine hormone of broilers exposed to heat stress in tropical area. The study used 140 male broilers of 2 weeks of age. The treatment of environmental temperatures were S1A (28.55?1.53 oC) with ad libitum of feeding, S1BT1 (S1 with pair feeding as S2A), S1BT2 (S1 with pair feeding as S3A), S2A (31.07?1.29 oC) with ad libitum of feeding and S3A (33.50?1.17 oC) with ad libitum of feeding. Variables measured were feed consumption, body weight gain, feed conversion and triiodothyronine hormone level of plasma. The experiment design used was a completely randomized design with 4 replications and continued to Duncan test when it was significantly different. The results indicated that feed consumption and body weight gain in S1A, higher than those in S2A and S3A. The body weight gain in S1BT1 higher than those in S2A, and in S1BT2 higher than those in S3A. The level of plasma triiodothyronine hormone in S1, S1BT1 and S1BT2 was higher than those in S2A and in S3A. Key words: heat stress, body weight gain, triiodothyronine hormone

Abstract

Twenty cattle were used in this experiment to determine the effect of administration follicle stimulating hormone (FSH) and pregnant mare serum gonadotrophin (PMSG) hormones on superovulation of Brahman cross cattle. The experiment was designed into completely randomized design with 5 treatments as follows. Treatments 1 (T1): 4 mg of FSH was injected twice a day intra-ovary, T2: 8 mg of FSH was injected twice a day intra-ovary, T3: 300 IU of PMSG was injected single dose intra-ovary, T4: 600 IU of PMSG was injected single dose intra-ovary, T5: 40 mg of FSH was injected intramuscular. All experimental cattle were oestrus synchronized using 15 mg of PGF2α  twice at 11-days intervals. Number of corpus luteum (CL) was detected by rectal palpation at day-7 after artificial insemination. Results showed that 19 cattle (95%) indicated oestrus sign. Eleven cattle (57.9%) showed oestrus sign 2 days after PGF2α  injection and the rest 8 cattle (42.1%) oestrus sign was detected at 3 days after PGF2α  injection. FSH and PMSG treatments increased significantly (P < 0.05) number of CL. The highest CL number was found in T5, meanwhile number of CL in T2 and T4 were higher compared to T1 and T3. The average treatment effect could produce 6.8±5.42 CL with range 2–26 CL. On the other hand single dose treatment of 600 IU PMSG (T4) showed high significant number of non ovulatory (persistent) follicle compared to other treatments (T1, T2, T3 and T5) on average number of persistent follicle 2.0±1.97 from 19 cattles. It is concluded that the best superovulation treatment was produced by injection 40 mg of FSH intra-musculary. Key words: Brahman cross, corpus luteum, PMSG, FSH

Abstract

Snack is popular for children and adult. It could be made by extrusion process. Snack is low in protein content because it is made up of cereal such as rice and corn. On the basis of nutritional and functional properties, egg was used in food industries. The objectives of the research were to analyze the nutrient content and in vitro digestibility of extruded snack from corn grits which was supplemented by egg white powder as a protein source. Randomized complete block design was used in this experiment with production periods as block. Water content was not significantly different between treatments. Supplementation with 10% egg white powder significantly increased the fat content of extrusion snack. Protein content and digestible protein increased significantly as increasing of egg white powder added. Protein digestibility of products with 10%, 15%, and 20% of egg white addition was significantly lower than those added with 0% and 5% egg white. Protein, fat, and carbohydrate linkage had formed porous product. This linkage affects product nutritive content and digestibility. Key words: egg, corn, extrusion, snack, digestibility

Abstract

This experiment was conducted to study the effects of addition of purified tannins at low concentration into hay diet on in vitro gas emission and rumen fermentation. Treatments consisted of: P0 (control hay), P1 (hay + 0.5 mg chestnut tannin/ml of incubation medium), P2 (hay + 0.5 mg/ml mimosa tannin), P3 (hay + 0.5 mg/ml quebracho tannin) and P4 (hay + 0.5 mg/ml sumach tannin). Variables measured were gas production kinetics, organic matter digestibility (OMD), methane production, expressed as percent methane in total gas and methane production per unit organic matter digested, and volatile fatty acid (VFA) production. The results showed that in most cases tannin addition at 0.5 mg/ml decreased significantly (P < 0.05) total and rate of gas production, OMD, total VFA and iso-VFA. Tannin addition also decreased methane production (P < 0.05). Hydrolysable tannins seemed to have better methane reduction effect than condensed tannins. The best tannin to decrease methane was chestnut tannin, which contained hydrolysable tannins. Present research should be shifted from evaluating only the effect of condensed tannins in reducing methane emission towards some potential hydrolysable tannins since the nature and the toxicity of hydrolysable tannins are quite diverse. Key words: methane, tannin, rumen, in vitro, hay

Abstract

The experiment determined the effect of the mixture of sago and tofu by-products fermented with Neurospora crassa on broiler performances. One hundred of broiler chicken were randomly divided into four groups of dietary treatments and five replications (5 birds each). The experiment was arranged in a completely randomized design according to dietary treatment tested, namely, none or 0% (RA), 7% (RB), 14% (RC) and 21% (RD) fermented sago and tofu by-products mixture. Experimental diets were formulated iso-protein (22%) and iso-energy (3000 kcal/kg). Variables measured were performances, carcass quality (meat cholesterol) of broiler and income over feed chick cost (IOFCC). Results of the experiment indicated that feed consumption, body weight gain, feed conversion ratio, nitrogen retention and carcass percentage were not affected by feeding fermented sago and tofu by-products mixture. Meat cholesterol indicated the lowest but IOFCC indicated the highest of RD group treatment mixture as compared to other treatment groups. It is concluded that feeding ration containing 21% fermented sago and tofu by-products maintains broiler performance similarly to that of control group, reduce meat cholesterol by 27% and increase IOFCC by 35.41%. Key words: sago by-product, tofu by-product, Neurospora crassa, meat cholesterol, broiler

Abstract

Bioconversion is a method to increase quality of high lignocellulose-containing feedstuffs. Fermentation occurs during bioconversion is influenced primarily by length of fermentation and mineral supplementation to the medium. This study was aimed at determining the effect of these two factors on dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and acid detergent fiber (ADF), and cellulose-to-lignin ratio of cocoa pod incubated with Phanerochaete chrysosporium. Twenty four treatments containing of 4 mineral supplementations (no mineral, Ca, Mn, and Ca+Mn) and 6 different lengths of fermentation (0, 5, 10, 15, 20, and 25 days) were designed randomly to 72 fermentation glass jars in a 4x6 factorial arrangement. Length of fermentation had significant effect on all parameters measured. Mineral significantly affected changes of DM and OM, NDF and ADF content, and cellulose-to-lignin ratio, but not DM and OM content. In conclusion, supplementation of Ca to cocoa pod incubated with P. chrysosporium for 15 days contributed positively (P < 0.05) to changes of OM (13.83%) and DM (11.30%). The cellulose-to-lignin ratio of 1.34 was the optimum result of Mn supplementation for 10 days incubation.

Abstract

An experiment examined the effect of the inclusion of different levels of shrimp waste meal (LUFb) fermented with Bacillus sp. in diets on growth performance and digestive organ weight of broilers. A total of 75 d-old broiler chicks were randomized in five treatments with 3 replicate pens of 5 birds each. Treatments consisted of 0 (control), and inclusion of LUFb of 5%, 7.5%, 10%, and 12,5% in the diets. Birds were offered with feed and water ad-libitum. Feed and birds were weighed weekly up to 35 day to calculate determine body weight gain, feed intake and feed conversion. At the end of experimental period, the birds were sacrificed and dress up to calculate carcass percentage and digestive organ weight. There was a significant negative linear response in body weight, feed consumption and feed conversion with increasing of LUF more than 5% in the diets, but carcass percentage was almost the same for all treatments. There was no significant response in digestive organ weight with increasing levels of LUF. The present result indicated that LUFb is potential feed ingredient to substitute part of dietary protein requirement of broiler but should be limited upto 5% to maintain growth performance, and digestive organ weight. Key words: shrimp waste meal, broiler, digestive organ

Abstract

What kind of comic book’s character was best suited to small sheep farmers, what was their preferred color, and what were the combined effects of such characters and color on the farmers’ knowledge about small sheep farm management? These questions directed researchers to design a 2x2 factorial quasi experimental study. Four farmer groups were involved in the study. The results indicated that the comic book characters’ effect on the farmers’ knowledge gains was highly significant; the comic book’s color effect on the farmers’ knowledge gains was also significant, and the combined effect of the comic book’s character and colors was not significant. Further tests demonstrated that the farmer group exposed to the colored comic book with human character performed much better than the other three groups in the posttests. So, the conclusion was that farmers preferred the colored comic book with human character to learn the small sheep farm management. Key words: comic book, story character, color, sheep management, farmer’s knowledge

Abstract

The objective of this study was to evaluate the effectiveness of carbohydrates supplementation on the stallion semen cryopreservation. Semen was collected from 3 stallions using artificial vagina twice a week. Collected semen was evaluated macro-and microscopically. Semen showed >60% progressive motility was then divided into 3 tubes and diluted with skim milk 1:1, centrifuged at 1006 g for 10 minutes. Supernatan was removed and each pellet rediluted either with skim milk extender supplemented with 50 mM trehalose (ST); 50 mM raffinose (SR) or 100 mM fructose (SF) with the concentration of sperm were 200x106 ml-1.  Extended semen packed into minitub 0.3 ml and equilibrates at 4 oC for 2 hours, freezes in the liquid nitrogen vapor for 10 minutes and stored in liquid nitrogen container -196 oC for further evaluation. After 24 hours, the semen was thawed at 37 oC for 30 second. The results of this experiment indicated that trehalose supplementation in skim milk was found to significantly improve the percentage of sperm motility (P<0.05) for stallion 1 and 3 compared to raffinose and fructose. But in all stallions, trehalose and fructose were superior compared to raffinose.Key words: Cryopreservation; stallion sperm; sugar
