Abstract

THE EFFECT OF SHADING AND NITROGEN FERTILIZATION ON MORPHOLOGICAL CHARACTERISTICS OF DWARF ELEPHANT GRASS (Pennisetum purpureum cv. mott). This study was conducted to determine the responses of Dwarf Elephant grass  (P. purpureum cv. Mott.) fertilized with different nitrogen levels and at different shading areas. A Completely Randomized Design (CRD) in a Factorial arrangement with 2 factors of nitrogen levels and shading areas arranged as follows: factor A = fertilization levels of P1 = without fertilization (0%); P2 = 200 kg urea/ha; P3 = 400 kg urea/ha; and P4 = 800 kg urea/ha; whereas factor B = shasing areas of N1 = no shading area (0%), and N2 = 70% shading area. Variables measured were including leaf length, number of mature leaves, and plant height. Research results showed that plants needed about 200 kg urea/ha in order to achieve maximum leaf length in shaded area;   whereas  plants  within  no  shading area needed about 800 kg urea/ha to achieve maximum leaf length. To achieve maximum number of mature leaves in open area without shading plants needed about 800 kg urea/ha, and no need for nitrogen fertilization in shading area for plants to achieve such a maximum number of mature leaves. The highest plant height was achieved at the level of 400 kg urea/ha fertilization at open area (no shading), and there was no need of nitrogen fertilization for plants in shaded area in order to achieve their  maximum height. It can be concluded that shading positively contributed to the availability of nitrogen to be used by Dwarf Elephant grass (P. purpureum cv. Mott.). In open area without shading, plants need more nitrogen in the form of urea to produce leaf length, number of mature leaves, and plant height compared to shaded area.Keywords: Fertilization, Shading, Elephant Grass, Plant morphology.

Abstract

EFFECT OF DUCK EGG WEIGHT ON FERTILITY, EMBRYO DEVELOPMENT AND HATCHING WEIGHT OF DAY OLD DUCK. This study was done to evaluate embryonic development for determination of egg fertility and hatching weight of day old duck (DOD). This study involved 160 eggs of duck with the average egg weight (EW) classified into 55g ≤  EW < 60g, 61g ≤ EW < 65g, 65g ≤ EW < 70g and 71g ≤ EW < 75g. Data collection was conducted over 28 days, as long as the period of hatching process. The design method used in this study was completely randomized design. Existing data were analyzed using analysis of variance. Treatments in this study were 4 treatments and 4 replications at each treatment. The variables measured were the percentage of egg fertility, embryo development and hatching weight. Results showed that duck embryo development during the hatching process was in good condition process. The results of variance analysis showed that treatments of egg weight did not affect significantly the percentages of egg fertility. The percentages of fertility were ranging between 85 – 95%. Hatching weights were ranging between 31g – 51g per DOD. Based on the results of this study, it can be concluded that egg weight had no effect on the process of embryonic development and fertility, except those for the hatching weight of DOD. Key words: Duck egg weight, embryonic development, fertility, hatching weight.

Abstract

EFFECT OF MOLASSES ADDITION ON PHYSICO-CHEMICAL QUALITY OF BANANA PEEL (mussa paradisiaca formatypica) SILAGE. Molasses had been used previously in animal feeds. The present study was conducted to determine physical and chemical composition as affected by the addition of molasses in ensiling process of banana peels. The study was conducted for four weeks at Department of Animal and feed Science Laboratory, Faculty of Animal Husbandry, University of Sam Ratulangi, Manado. A Completely Randomized Design (CRD) arranged by 4x3 factorial with three replications was employed for analysis of varians. The two factors consisted of : A factors (level of molasses addition) were: A0=0%; A1=2%; A2=4%; and A3=6%; and B factors (incubation time) were : B1 = 14 days ; B2 = 21 days; and B3 = 28 days. Tukey’s test was used to analysis treatment differents. Variables measured were : smell, texture, color protein(%) and gross energy (Kcal/kg). The result show that the addition of molasses in ensiling process of banana peels was positively (P<0.05) interacted with incubation times, and affected on smell, crude protein, and gross energy contents, but not affected towards texture and color (P>0.05) of banana peels silage. The addition of molasses up to 6% with incubation time of 28 days gave an intermediate texture and brown color and these could be a good indication of a good or success ensiling process. The addition of molasses up to 6% with an incubation time of 21 days produced banana peels silage with protein content of 6,77% and addition of molasses up to 4% with incubation time 28 days gave gross energy of 4.390 kcal/kg. It can be concluded that addition of molasses up to 6% with incubation time 21 days produced good quality (physically and Chemically) of banana peels silage. Key words : banana peels, molasses, ensiling process, protein and gross energy content.

Abstract

ABSTRACT CARCASS QUALITY OF BROILERS FED RATION CONTAINING WASTE OF SAWI. Study was conducted to evaluate the effect of substituting part of ration with sawi waste meal on carcass quality and abdominal fat of broilers. Total of sixty unsexed day old chick broilers of MB-202 P strain were randomly divided into twenty units of pens, each of pen was filled with three heads of chicks.  Birds were maintained during forty days. Levels of substituting part of ration with sawi waste meal were  0, 5, 10, 15, and 20 percents. Each treatment had four replications using completely randomized design with 5 x 4. Fresh water and ration were given ad libitum. Birds from day old chick to the age of twenty one days old were fed with BR-21E ration for all treatments. The treatments of ration were fed at ages of twenty two days old to the end of study (period when all animals were slaughtered). Data were analyzed using F test and Tukey test for the significant F test. Results showed that control treatments were significantly different (P<0.05) with those others four treatments for carcass weight, but not significantly different with those others four treatments for carcass percentages and abdominal fat. Therefore, sawi waste meal can be used to substitute part of ration up to 20 percents for broilers ration in term of the carcass percentages and abdominal fat.   Key words: Sawi waste meal, broilers, carcass quality.
