Abstract

The objective of this research was to determine the effects of dietary cation-anion difference (DCAD) on acidity of ration, blood, vaginal mucous, and urine, number of fetus, number of offspring, and offspring sex ratio. The treatments were rations with DCAD -28, -18, 0, +14, and +32 meq which were offered to 15 ewes. This research used randomized complete block design. There were three groups, (I) ewes previously had twin female offsprings; (II) ewes previously had twin male offsprings; and (III) ewes previously had twin male and female offsprings. Results of this study showed that there were no differences observed for blood's pH, vaginal liquid's pH, offspring number, and offspring sex ratio. Increasing DCAD affected ration's pH, urine's pH, and number of fetus for each ewe. Blood's acidity was not affected by DCAD, but DCAD -28 meq reduced acid of blood, metabolic acidosis, and urine; the number of fetus and offspring. DCAD -28 meq might be anions excessive in the ration. DCAD 0 meq was relatively the best of ration because gave the normality of blood, metabolic, and urine, also relatively the highest of fetus and offspring. The offspring sex ratio related to vaginal mucose pH when artificial insemination was applied (r= 0.75) and ration's pH (r=0.47). Ewes previously had twin female lambs gave the number of fetus and offspring sex ratio were 2.00+0.71 and 0%, respectively. Ewes previously had twin male lambs gave the number of fetus and offspring sex ratio were 2.80+1.30 and 15.00+8.50%, respectively. Ewes previously had twin male and female lambs gave the number of fetus and offspring sex ratio were 1.60+1.14 and 61.75+31.50%, respectively.Key words: DCAD, pH, offspring sex ratio, lamb, ewe

Abstract

Quality improvement of ramie leaves silage by the addition of water soluble carbohydrates (WSC) sources as many as 20% W/W fresh substance (FS) prior to 42 days of ensiling time was conducted in two experiments. First experiment examined three carbohydrate sources (cassava meal, pollard and coarse grinding corn) for their capacities to improve physical (color, odor, texture and spoilage), fermentative (pH, protein degradation, organic acid profiles), and utilities characteristics of the silages for ruminants (rumen fermentabilities and digestibilities) in vitro. The silages had bright greenish brown of color, lactic acid odor, and firm textures, categorized as highly fermentable and digestible feeds (dry matter digestibility >72%). Compare to other additives, cassava meal produced better silage. However, high butyric acid and protein degradation proportions in the silage were not seem in line to these data. Coarse grinding corn failed to do its function therefore produced poor silage quality. Second experiment was designed to confirm the previous results. Five carbohydrate sources (cassava meal, pollard, fine grinding corn, rice bran, and cassava extract meal) of the same functions were examined. The results confirmed that cassava meal produced very good ramie leave silages (Fleigh number >80) while the others produced quite good ramie leaves silage qualities (Fleigh number 40-60). All additives used in the second experiment successed to serve their functions in improving ramie leave silage qualities.

Abstract

Chromium (Cr) is an essential mineral for ruminants. Its metabolism and interactions with other minerals has not been widely known. This experiment was designed to evaluate the utilization of minerals and growth of Garut ram fed ration supplemented with Cr and different Dietary Cation Anion Balance (DCAB) and Ca level. Dietary treatments, namely: R0 (Ration with DCAB+14); R1 (Ration with DCAB+14 + Cr 3ppm,); R2 (Ration with DCAB 0 + Ca); R3 (Ration with DCAB 0 + Cr 3 ppm + Ca), were allocated in twenty four of 1.5-2 years old Garut rams in a randomized block design. The results showed that Cr supplementation in rations containing different levels of Ca did not affect feed intake, body weight gain, and dry matter digestibility, but reduced the absorption of Cr and  Ca of the low Ca diet. Supplementation of Cr had no effect on Cr, Ca, Zn, and Mg status in blood and semen of the rams. Level of Cr intake had negative correlation with Ca absorption and positive correlation with blood Cr levels. There is a positive relationship between level of Ca intake with Ca and Mg absorption and blood Ca and Zn levels. Intake of Cr and Ca was not related to the semen Cr and Ca levels.

Abstract

Cobalt (Co) is required by rumen microorganism for vitamin B12 synthesis. Vitamin B12 is an important cofactor for methionine synthesis and gluconeogenesis. In young ruminants up to 6–8 wk old, the rumen has not been completely developed and rumen microorganisms are not ready to supply vitamin B12. The aim of this research was to determine the potency of mixed rumen bacteria and dietary supplementation of Co and its effect on plasma glucose, blood minerals (Co, Fe, and Zn) concentrations, and hematology of pre-weaning twin lambs. Twelve one month-old local twin lambs were assigned to 4 groups in a randomized complete block design. Lambs were fed cow milk at 10% body weight, adjusted weekly for 80 d. Mixed rumen bacteria were offered at 15 mL/d (8.295x1010 cfu). Dietary treatments were: 1) basal diet (Control), 2) basal diet + 1 mg/kg DM cyanocobalamin (VitB12) and 3) basal diet + 1 mg/kg DM of Co + administration of 15 mL mixed rumen bacteria (CoBac). There were no treatment effects on neither plasma glucose and blood mineral concentrations nor hematological profiles. This study demonstrated that pre-weaning twin lambs are not responsive to supplementation of Co and administration of mixed rumen bacteria.
