Abstract

The purpose of this study was to determine changes in the linear body size of male goats which were given complete silage based on Sorghum bicolor, Pennisetum purpuphoides and natural grass. The variables studied were body length, chest circumference, and shoulder height. The research method used was a Completely Randomized Design with the treatment given was TI: Sorghum bicolor 45% + Leucaena leococephala 20% + Corn 25% + pollard 10%, T2: Natural Grass 45% + Leucaena leococephala 20% + Corn 25% + Pollard 10%, Q3: Pennisetum purpuphoides 45% + Leucaena leococephala 20% + Corn 25% + pollard 10%. The results showed that shoulder height, body length and chest circumference in male goat goats for the three treatments using natural grass-based (T1), Pennisetum purpuphoides (T3) and Sorghum bicolor (T2) silage feed showed relatively similar results and had no effect. real. It was concluded that the use of different forages (natural grass, Sorghum bicolor, and Pennisetum purpuphoides) as the basis for making complete silage can increase the linear growth of a relatively similar body of goat nuts. The use of Sorghum bicolor (T2) in the manufacture of complete silage showed a higher body length, chest circumference, and shoulder height between treatments (T1 and T3).

Abstract

The purpose of this study was to determine the glucose and urea profile of Bali bovine blood fattened with complete feed containing different levels of crude protein (PK). Cattle used by male Bali cattle are 2 - 2.5 years old with an initial weight of 200 kg. The rations used in the manufacture of complete feed are prepared with feed ingredients such as: natural grass, gliricida sepium, rice bran, corn flour, pollard bran. The variables measured in the study were blood glucose and blood urea of male Bali cattle. The method used is an experimental method using a completely randomized design (CRD) with the following treatment: T1: 27% Natural Grass + Gliricida sepium 10% + Corn Flour 34% + Pollard 15% + Rice Bran 14% T2: Natural Grass 27% + 20% Gliricida Sepium + 18% Corn Flour + 15% Pollard + 10% Rice Bran T3: 27% Natural Grass + 13% gliricida sepium + 20% Corn Flour + 15% Pollard + 7% Rice Bran The results of this study indicate that, the use of complete feed with different PK levels does not affect the glucose and urea levels of blood of Bali bulls (P> 0.05). Where the blood glucose level for each treatment is, T1: 92,392 ± 9,779, T2: 87,448 ± 7,905 T3: 93,717 ± 14,969 while the blood urea levels for each treatment are T1: 44,629 ± 5,663, T2: 45,473 ± 4,152, T3: 44,543 ± 8,343. Based on description of the results of the research that has been done, it can be concluded that the provision of complete feed with PK level (11%, 13%, 15%) at 72% TDN has the same effect for all treatments and produces blood glucose and urea levels in the normal range.

Abstract

This research was conducted in the enclosure of the Faculty of Agriculture, University of Timor, Sasi sub-district, Kefamenanu city, North Central Timor district for 42 days from April to May 2021. The aim of the study was to determine the effect of L-arginine supplementation in feed on the digestive organs of broiler chickens. This study used 96 Day Old Chick broilers. The research method used was a completely randomized design (CRD) consisting of 4 treatments and 4 replications. Each experimental unit consisted of 6 broilers. The treatments given consisted of T0: control feed, T1: control + 0.5% L-arginine, T2: control + 0.75% L-arginine, T3: control + 1.00% L-arginine. The variables observed were liver weight, bile weight, pancreatic weight, gizzard weight, intestinal length and small intestine weight. The data obtained were analyzed using statistical package software for the social sciences (SPSS 20). The analysis showed that the addition of L-arginine had no significant effect (P<0.05) on liver weight, bile weight, pancreatic weight, gizzard weight, intestinal length and small intestine weight. Based on these results and discussion, it can be concluded that the supplementation of the amino acid L-arginine 0.75% in broiler chicken feed can affect the weight of the digestive organs of the gizzard, while the weightof the liver, bile, panceas, intestinal weight have on significant effect.
