Abstract

This study aims to determine the effect of calcium supplementation in feed on the blood profile of broilers chickens. This research was conducted in a broiler chicken coop, owned by breeders in Sasi Village, Kefamenanu City District, North Central East District. This research was conducted from July to August 2020. This study used 96 broilers. The method used in this was a completely randomized design consisting of 4 replications and 4 treatments. The treatments given were T0 (control diet), T1 (calcium supplementation 1,00 %), T2 (calcium supplementation 1,50 %), T3 (calcium supplementation 2,00 %). The variables observed in this study were the content of erythrocytes, hemoglobin, and blood leucocytes. The data obtained were analyzed using analysis of variance. Analysis of variance showed that the treatment had no significant effect on erythrocytes, hemoglobin, and leucocytes of broiler chickens. It was concluded that the addition of calcium in feed at different levels did not increase the content of erythrocytes, hemoglobin, and leucocytes of broiler chickens aged 6 weeks.

Abstract

This study aims to determine the consumption of  nitrogen free extract (NFE), crude fiber (CF) and extract eter (EE) of male kacang goats in the feed restriction phase after experiencing different levels of feed restriction. The study used an experimental method with a completely randomized design (CRD) which consisted of 3 treatments and 5 replications, namely: T0: Cattle without food restrictions, T1: Cattle were limited to 100% feed according to maintenance life and T2: Cattle were limited to 50% of maintenance life. The results showed that the consumption NFE of natural grass of treatment T0 and T1 was relatively the same, but higher than T2 (P<0.05); conversely the consumption of NFE of concentrate was relatively the same (P>0.05) among the treatments; while the total consumption of NFE of natural grass and concentrate treatment T1 and T2 was relatively the same (P>0.05) and lower (P<0.05) than treatment T0. Consumption CF of natural grass in the T0 and T1 treatments was relatively the same (P>0.05) and higher (P<0.05) than the T2 treatment; On the other hand, the total consumption CF of natural grass and concentrates in the T1 and T2 treatments was relatively the same (P>0.05) and lower (P<0.05) than the T0 treatment. Likewise, the consumption EE of natural grass in the treatment of T0 and T1 was relatively the same (P>0.05) and higher (P<0.05) than treatment T2. The consumption of NFE and CF concentrates from the three treatments was relatively the same (P>0.05); Likewise, the consumption EE of concentrate and total consumption EE of natural grass and concentrate from male kacang goats in the feed restriction phase of the 3 different groups was not significant (P>0.05). Consumption of NFE for each treatment was T0 of 131.66 ± 41.42, T1 of 84.85 ± 38.88 and T2 of 83.70 ± 0.03. Consumption of crude fiber (g/head/day) for each treatment was T0 of 42.89 ± 6.33, T1 of 33.73 ± 9.52 and T2 of 26.96 ± 0.03. Consumption of extract eter (g/head/day) for each treatment was T0 of 5.52 ± 2.24, T1 of 3.23 ± 1.85, and T2 of 3.53 ± 0.00. It can be concluded that the restriction of feed (feed restriction) up to 50% of the maintenance life does hinder the livestock growth process, but does not interfere with the health status of goats (indicated and physiological status are in the normal range).
