Environmental conditions pose direct and indirect effects on animal growth. Animal growth itself can be defined in many ways, and one of the parameters is body growth. This study was conducted to determine the dimensions of body measurements such as shoulder height (SH), body length (BL), chest width (CW), and heart girth (HG) of calves and heifer located in high land, middle land, and low land. The number of calves and heifer used in this study was 121 and 131, respectively. Calipster and rondo ribbon were used to measure the body measurements while the Gompertz model was used to predict the growth parameters of mature age. The results indicated that the maturity age of cattle raised in the high land, middle land, and low land were 347.63 - 371.52 days, 377.58 days, and 465.69 days, respectively. The growth rate for all body measurements (SH, BL, CW, HG) was higher in the high land compared to the middle land and low land. The sequences of growth development obtained from the Gompertz analysis was SH, CW, HG, and BL. Heifer reaching earlier puberty or mature age will have better body size.

The aim of the experiment was to find the most appropriate supplement for sheep fed on vegetable waste silage–based diet to produce better weight gain. Sixteen male local sheep (average body weight of 13.27+2.82 kg ) were randomly divided into four groups according to completely randomised design. Each group received one of four treatments i.e. T0 (50% field grass + 50% concentrate), T1 (50% silage of vegetable waste + 50% concentrate), T2 (T1 diet + mineral Zn 20 ppm, Cr 2 ppm), and T3 ( T2 diet + 1% alginate). After two weeks of preliminary period, sheep were subjected to 12 weeks of observation. In general, the vegetable waste silage based diet (T1,T2, T3) resulted in better crude protein (CP) intake and weight gain than the T0 diet. Each treatment of T0, T1, T2, and T3 resulted in Protein consumption of 36,48 ; 45,81 ; 53,59 ; 40,75 g, and weight gain of 75; 105; 121; 109 g/day, respectively. Mineral supplementation (T2) resulted in higher rates of weight gain and feed efficiency compared to the mixed mineral and alginate supplementation (T3), therefore leading to the conclusion that only Zn and Cr mineral supplementation is needed for the vegetable waste silage used as sheep ruminant feed.

The addition of certain fruit juices to milk products as a way to create new flavor has been known to also cause an interaction between the fruit juice and the components of the milk product. The mechanism of gelatinization in milk products as a result of adding the passion (Passiflora edulis Sims) fruit juice and by processing methods like heating and acidity will influence the final milk product. In this study, the mechanism of gelatinization is established through the observation of the products’s microstructure. This study was arranged factorially according to Completely Randomised Design. The first factor was passion fruit juice concentration (7.5 and 10%) and the second factor was ripening time (0, 1, 2 and 3 weeks). The variables observed were physical properties, which was done by the measurement of pH and lactic acid concentration. The changes in physical properties were monitored by observation of product microstructure by light microscopic with histopathological technique. The best cheese product was achieved with a passion fruit juice concentration of 10%. The product observed had a more compact microstructure at a ripening time of 3 weeks with pH of 4,29 and lactic acid percentage of 1.27

This research was conducted to determine the resistance degree of lactic acid bacteria (LAB) isolated from the faeces of broilers towards various intestinal conditions, in order to select a lactic acid bacteria to be used as prospective probiotic. Ten types of LAB bacteria (M1, M2, M3, M4, M5, M7, M8, M23 ,M26, and M28) isolated from the faeces of broiler chicken were subjected to pH2, pH3, and pH4; to 3% bile salt and to the temperatures of 30oC, 37oC and 41oC. The results of the research showed that all LAB isolates experienced the highest colony reductions at pH2, which was around 3.2-5.5 log units/ml. The reduction of colony numbers at pH3 was approximately 1.8-3.1 log unit/ml, and the reduction at pH4 was around 1.0 – 2.5 log unit/ml. All the LAB isolates experienced a decrease of 0.5 log unit/ml to 1.6 log unit/ml in colony numbers after bile salt exposure. The reduction of colony numbers of ten LAB isolates at the temperatures of 30oC, 37oC and 41oC was 0.6 - 1.4 log unit/ml ; 0.1 – 0.5 log unit/ml and 0.7 – 1.4 log unit/ml, respectively. None of the ten isolates posses all of the expected characteristic, however based on its more superior ability to block the pathogenic micro-organism as well as its ability to survive in simulated gastro intestinal tract conditions, M1 was selected as prospective probiotic.

The purpose of this research was to determine the effect of the duck farmer’s attitude on their income in livestock enterprises of Tegal ducks. Income was measured by the Revenue Cost Ratio, which is the ratio between revenues and expenditures cost that will show the level of profit achieved. The research was conducted in October to November 2012, in Gapoktan Purwadiwangsa, Pesurungan Lor Village, Margadana District, city of Tegal. This research was carried out using the survey method and observation method. The determination of respondent size was done using simple random sampling of as many as 100 duck farmers. The analysis of data was performed using the linear regression model of Y = β 0 + βX + δ with SPSS version 17.0. The variables in this research were, Y = Income (Revenue Cost Ratio), and X = Attitude of farmers . The research results showed that the average duck farmer display attitude (cognitive, affective and psycomotoric) in the good category. The average income was Rp 28.822.292 with an average business scale of 511 heads. The profit for each duck was Rp 56.403, and with a Revenue Cost Ratio (RCR) of 1,25, it meant the farmers ducks profited 25% per period. The attitude of duck farmers affected income by as much as 59.6%.

The objective of the study was to determine the effect of nitrogen fertilization and water stress on the stomatal aperture, chlorophyll and proline accumulation of Napier grass (Pennisetum purpureum Schum.) The effect of water stress and nitrogen fertilizer levels were evaluated within an arrangement of Completely Randomized Design with factorial pattern (2x3). The variables observed were stomatal aperture, total chlorophyll and proline content. The results showed interaction between water stress and the level of fertilization. Interaction between water stress with nitrogen fertilization showed that the stomatal openings were more narrow (P<0.05) in water stressed plants compared to plants with excess water and that decreased stomatal aperture was not significant (P>0.05) with increasing levels of nitrogen fertilization either with sufficient water or with water stress. The exception is treatment of enough water and fertilizer 250 kg N/ha (P<0.05) where stomatal aperture decreased compared with no fertilizer. The total chlorophyll content of both the sufficiently watered and the water stressed Napier grass on nitrogen fertilizer rose with increasing doses of nitrogen fertilizer. The conditioning of water stress with fertilizer dose of 0 kg N/ha and 150 kg N/ha did not increase the total chlorophyll, however a dose of 250 kg N/ha resulted in an increase of total chlorophyll (P<0.05). Interaction between water stress and nitrogen fertilizer levels showed that the content of proline rose (P<0.05) with increasing levels of nitrogen fertilization, as well as with water stress treatment (P<0.05). It is concluded that water stress on Napier grass plants lowers stomatal aperture width, but increases proline accumulation and nitrogen fertilizer increases total chlorophyll and proline accumulation. There was an interaction between nitrogen fertilizer with water stress.

The objective of the sudy was to determine the physical characteristics of the eggs of Mamoa bird which includes several components, namely weight, shape, shell color, length, diameter, egg index, percentage of egg white (albumen), percentage of yolk (yolk), eggshell weight, Haugh unit (HU), and the thick shell. Based on the results and discussion, it concluded that the average egg weight of 98.17 ± 7.78 g birds Mamoa . Comparison of yolk, albumen and shell was 68.37 ± 2.55%, 23.82% ± 2.61 and 7.82 ± 0.31%, while the value of HU was 69.42 ± 3.55.
