Abstract

The study was aimed to determine the optimal time to evaluate the maximum numbers of swollensperm after expose to hypo-osmotic solution for testing membrane integrity in fresh garut ram semen. Atotal of 24 ejaculate samples from eight sexually mature garut ram were collected using artificial vagina.After macroscopic evaluation, 10 μL undiluted semen was gently mixed in each of the 2 mL hypoosmoticsolution and incubated at 37oC for 1 hour. Two hundred of coil and non-coiled sperm wereobserved from five different fields every 15 minutes. Results demonstrated that the maximumpercentage of coiling sperm positive to HOS test was at 30 minutes and no differences among 8 garutrams used.

Abstract

This studywasaimed to examine the development and function ofdigestive organsof lamb in digesting feed based on feed digestibility valueandeating behaviour. The materials used were 11 lambs aged 3-4 months, body weight(BW)14.78 ± 1.99 kg (CV 3.98%), and 11 ramsaged 10-12 months, BW 22.18 ± 1.81 kg (CV 3.29%). The study used a completelyrandomized design of 2x2 in nestedpatterns. There were two ages compared (lambs vs ram) and every age was nested the diet i.e.100%Napiergrass (G100) vs mixed pellet 50% grass and 50% concentrate(G50C50). The diet was given at 3.5% of BW. Parameters observed were dry matter intake(DMI)and digestibility, eating and ruminating time. The results showed that were no significant differences between lambs and rams in DMI (averaged 3.33% BW),digestibility (averaged 49.00%), eating (192.56 min/d), and ruminating (364 min/d). Animalsgiven diet G50C50 had higher (P<0.05) DMI (666 vs 565 g/d), digestibility (50.49%vs 47.53%), and less (P<0.05) eating (47 vs 338 min/d) and ruminating (305 vs 423 min/d), as compared withthose fed diet G100.It is concludedthat the digestive tracts of lambs had developed and function to the stage similar to ram.

Abstract

The experiment was carried out to investigate the effect of feed withholding in the very early life ofbird on its compensatory growth capacity and fat parameters. A total of 60 mixed-sexes of one day oldRoss chicks were used in the experiment conducted with completely randomized design of 2 differentfeeding times after hatching, i.e.: T1: given access to feed and water ad libitum immediately afterhatching until 35d of age; and T2: withheld from feed (fasted) but not from water for 48h after hatchingand then fed ad libitum until d35. The birds were weighed at the start of experiment and weeklythereafter, and DWG was then calculated. Feed intakes and FCR were also recorded weekly. At d36,abdominal fat was taken out from 2 birds per pen and was weighed. Breast meat (skinless) from thesame birds was also sampled for total FA analysis. Final BW (d35) and total feed consumption of earlyfastedbirds were 1935.17±43.90 kg and 2745.55±47.48 kg and those of unfasted birds were2019.00±50.85 kg and 2910.84±128.10 kg, respectively. FCR of early-fasted and unfasted birds at d35were 1.42±0.03 and 1.45±0.07. The magnitude difference of DWG between early-fasted and unfastedbirds was 27% at d7, whereas at d35 the difference was only 4.5%. Abdominal fat percentage to live BWof early-fasted birds was 1.65±0.09% (male) and 1.60±0.10% (female) and that of unfasted birds was2.00±0.19% (male) and 1.89±0.38% (female). Total FA contained in meat of early-fasted and unfastedbirds were 0.82±0.10 and 0.85±0.10 g/100gDM. Overall, BW and feed consumption of early-fastedbirds were significantly lower (P<0.05) than unfasted birds. DWG, FCR, abdominal fat and total FAcontained in meat were not significantly different (P>0.05) between early-fasted and unfasted birds. Inconclusion, holding birds without feed following hatch (under practical conditions) may limit thecompensatory growth capacity of birds in the later age. Fasting applied in the very early life of broilerleads to impairment of cell hyperplasia resulting in permanent stunting. Abdominal fat and total FAcontained in meat might not be affected by fasting for 48h after hatching. The degree or duration of feedwithholding (for 48h after hatching) might not sufficient to reduce adipocyte proliferation or the numberof precursor adipocytes.

Abstract

The study was aimed to predict body composition of local goats fed bagasse based total mixedration (TMR). Fifteen male local goats (18 months old with average body weight of 18 kg ) were used inthis study. Goats were divided randomly into 3 groups, and were fed TMR’s those contained 15, 25, and35% of sugarcane bagasse, respectively. All experimental diets were designed to be isoenergy andisoprotein. After 12 weeks of adaptation to experimental diets and environment, each group wassubjected to feed digestibility trial, body composition, and experiment of feeding effect on serumglucose. The data were analyzed using one way analyses of variance. The results showed that the bodycomposition and serum glucose concentration were not significantly different (P>0.05) amongtreatments. The bagasse portion in the TMR upto 25% lowered daily feed consumption and body weightgain (P<0.05). It was concluded that the use of sugarcane bagasse up to 35% in the TMR did not affectbody composition of goats.

Abstract

The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

Abstract

The objective of this study was to evaluate the total pancreatic -cell number of chicks in firstcrossbred (F1) with potential as broiler. The total number of twenty day-old male chicks consisted ofDOCs Cobb 500 broiler line as a control group and those of Pelung and the crossbred of Pelung andCemani chicks with the average body weight of 30 gram as materials. They were divided into fourgroups, in which each group has 5 male DOC's. Group 1 was DOCs from parent of Cobb 500 broiler asthe control; Group 2 was DOCs from parent of Pelung; Group 3 was crossbred DOCs from male parentCemani line and female parent Pelung line; and Group 4 was crossbred DOCs taken from male parent ofPelung and female parent of Cemani. Chick body weight of each group was measured at 7th week.Histological process was carried out on five DOCs of each group previously raised until seven weeksold and at the end of experiment all chicks were euthanized for pancreatic organs, particularly tissuesamples of pancreas, made as histological preparates. Data from the histological probe on totalpancreatic -cell number was statistically analyzed using the ANOVA of One Way Classification, andthen followed by the LSD-test. Result of the study showed that average body weights of DOCs in thecontrol group of Cobb 500 (2770±58.31) significantly higher (P<0.05) compared to the groups of 2, 3,and 4 (652.4±32.77, 570.4±14.45, and 628±37.2 g, respectively). Total pancreatic -cell number in thecontrol group of Cobb 500 broiler chicks (2.76x106±0.20x 106) significantly higher compared to thegroups of 2, 3, and 4 (1.93 x106±0.34 x106, 1.64x106±0.30x106, and 1.71 x106±0.19 x106, respectively).The results of this study revealed that total pancreatic -cell number can be used as an indicator of thegrowth and development of chick.

Abstract

This experiment was conducted to evaluate the effect of extract of plants containing tannin on invitro CH4 production, fermentation characteristics and nutrient degradability. Six of plant leaves i.e.Gliricidia sepium, Acacia mangium, Leucaena leucocephala, Desmodium intortum, Camellia sinensis,Calliandra calothyrsus and seed of Areca catechu were extracted by using water. Experimentaltreatments consisted of P. purpureophoides (300±5 mg) incubated alone or added with 1.2 mL of plantextracts. The in vitro neutral detergent fibre (NDF) degradability was determined using the first stagetechnique of Tilley and Terry. The results showed that total tannin concentration of plant extract rangedfrom 34 to 95 g/kg DM, and was lowest in D. intortum and highest in A. mangium. Methane productionwas significantly (P<0.001) lower with addition of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus extracts compared to control. Total tannin had a close relationship with CH4production (r=-0.79). There was strong correlation between CH4 production and NDF degradability(r=0.61). It was concluded that water extracts of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus have potential to be used as rumen manipulator in order to reduce CH4 production inruminants.
