Abstract

Collagen is the main ingredient in the gelatin manufacture. The purpose of the study was todetermine the pH value, the swelling percentage and collagen yield of chicken shank bones which weresoaked by different HCl concentration and soaking time. The pH value and swelling percentage ofchicken shank bones are indicator that determines amount of collagen yield. The research design usedwas factorial completely randomized design (CRD). Factor A was a concentration of HCl (2%, 3.5% and5%) and factor B was a soaking time (24, 36 and 48 hours) without replication (profile). The resultshows that the the increase of HCl concentration and soaking time affected on the decreasing of pHvalue profile (0.17-0.85), swelling percentage profile (80.25-97.49%) and also collagen yield (1.80-10.02%). The lowest collagen yield of chicken shank bones was suspected caused by the used of Hcl.The highest result of the study was using 2% of HCl concentration for 24 hours. The best result wasfound in the use of 2% HCl and was soaked for 24 hours. Based on those result, the collagen of chickenshank bones was recommended as a main ingredient for gelatin manufacture.

Abstract

Digestibility is a description of the ability of feed material that can be utilized by livestock. Higher digestibility of feed material means the total amount of feed content that can be digested in the digestive tract. This study aimed to obtain the proportion of the use of fermentation concentrate in rumen fermentation based on in vitro. The feed used consisted of 7 treatments as follows P1 (20% Pennisetum purpureum: 80% concentrate), P2 (30% P.purpureum : 70% concentrate), P3 (40% P.purpureum : 60% concentrate), P4 (50% P.purpureum : 50% concentrate), P5 (20% concentrate: 80% P.purpureum), P6 (30% concentrate: 70% P.purpureum) and P7 (40% concentrate: 60% P.purpureum). Dry matter digestibility (DMD) and organic matter digestibility (OMD) were done using Theodorou method. Gas production was measured when the samples were incubated at 39oC in the waterbath incubator at hours 2, 4, 6, 8, 10, 12, 24, and 48. Approximately 0.75 g of feed formulation was mixed with 75 mL of rumen fluid buffer. The rumen fluid is taken from 3 fistulated cattles prior to morning feeding. A complete randomized design with three replicates was used. Asymptotic gas production and kinetics were estimated by the Orskov’s model. The results of this study showed that P2 and P3 treatment showed the best digestibility among others treatment with 71.63% ; 71.06% of DMD and 76.42% ; 71.65% of OMD. In conclusion, P2 and P3 treatment can be used as feed for beef cattle.

Abstract

An experiment with 480 day-old chicks of four commercial strains was conducted to study theeffect of genotype on response in body composition to variation in dietary protein: energy ratios. Thechicks were randomly allocated into 4x2x4 factorial and fed on a commercial starter diet (250 g CP and12.5 MJ of ME /kg) from hatching to 5 d of age and divided into two groups with three replicationseach of 16 birds and given either the such starter diet (S) or a finisher diet (F) containing 190 g CP and13.0 MJ of ME /kg. The birds were reared in strain-and sex-intermingled groups in brooders and followoncages until they reached the target body weight of 600-650 g (females) or 650-700 g (males) andtransferred to single cages and fed S or F diet until 1200-1300 g (females) or 1300-1400 g (males). Thelighting program was 23 h light for the first two days, and reduced to 18 h/d for the remainder of theexperiment. There were considerable variations in relative growth performance, FCR, carcass fat andabdominal fat due to genotypes and dietary regimen. Although birds tend to response in similar waywhen dealing with the excesses and insufficient supply, the nutrient requirements in relation to theprotein: energy ratios should be designed according to genetic background.The accumulation of fatduring the growing period was primarily due to the genetic variation whereas beyond this age, variationin abdominal fat was due principally to dietary effects.

Abstract

The purpose of the research was to assess the effect of α-tocopherol and ascobic acids on the performance and immunity blood profile of male native Muscovy duck. The materials used were 84 male Muscovy ducks at 9 weeks old. The research used completely randomized design with 7 treatments. The treatments were E0C0 : basal diet without α-tocopherol and ascobic acids, E400: basal diet+ α-tocopherol 400IU, E600: basal diet+α-tocopherol 600IU, C400: basal diet+ascorbic acid 400mg/kg, C600: basal diet+ascorbic acid 600mg/kg, E200C200: basal diet+α-tocopherol 200IU+ ascorbic acid 200mg/kg, and E300C300: basal diet+α-tocopherol 300IU+ ascorbic acid 300mg/kg. Each treatment was repeated 4 times and each replication consisted of 3 ducks. The observed variables were body weight, feed consumption, feed conversion ratio, packed cell volume (PCV), total of plasma protein (TPP), leucocyte count, basophil, heterophil, eosinophil, monocyte, lymphocytes count and heterophil/lymphocyte (H/L) ratio of Muscovy duck. The result indicated that E0C0, E400, E600, C400, C600, E200C200 and E300C300 had no significant difference in body weight, feed intake and feed conversion. There were significant effects on PCV, leucocyte count, percentage of heterophil and lymphocytes, but had no significant effect on eosinophil, monocyte and the H/L ratio. The C400 resulted a higher PCV count, percentage of heterophil, and H/L ratio. The C 600 produced the highest leucocyte count. In conclusion, the supplementation of ascorbic acid at 400 - 600 mg/kg feed ascorbic acid could improve theimmune profile, but could not improve the performance of Muscovy duck.

Abstract

Post-mortem spermatozoa recovery is an important technique for obtaining germplasm reservesfrom genetically valuable animals or endangered species. The purpose of this study was to studywhether ram spermatozoa within epididymides stored at 4º C for 24 and 48 h remain their motility andviability. The characteristic of ram epididymal spermatozoa after freezing and thawing was alsoobserved. Six pairs of ram testes with attached epididymides were used in this study. The motility ofcontrol spermatozoa was well maintained throughout the dilution procedure (83.3±1.1, 80±1.3, and80±1.3% for collection, Niwa and Sasaki freezing -1 extender (NSF-1 and NSF-2 groups respectively);but declined (P<0.05) after freezing and thawing (38.3±3.1%). Motile and viable spermatozoa could berecovered from epididymides up to 48 h of storage, although their quality declined significantly(P<0.05) as post-mortem storage time increased (motility: 83±1.2, 67±3.0, and 46±5.1; viability:84.2±2.4, 73±2.8, and 66.6±2.6 % for control, 24 h and 48 h group respectively). These data indicatethat ram epididymides could be stored at 4º C for 48 h when epididymal spermatozoa cannot beimmmediately collected and cryopreserved. These storage conditions might be possible to use forepididymal sperm recovery in wild ruminants.

Abstract

Selection of livestock was purposed to increase productivity. A performance test was conducted using 25 males and 25 females of Sumba Ongole (SO) cattle. The performance test were conducted in three periods (2014, 2015 and 2016) for about 535 days. Descriptive statistics ws used to analyze data of body weight. Cattle with age between 300 to 600 days were used for evaluation. Result showed that heritability value of yearling weight (YW365) was 0.77+0.68 as a high category. The highest breeding value of YW365 were 66.05 kg (male) and 41.89 kg (female). The average of corrected final weight (CFW) weight were 172.55+34.22 kg (male) and 159.80+37.73 kg (female). The performance test in this study obtained six A class (1 bull and 5 cows) based on the standard minimum of body measurements for SO cattle.
