Abstract

This study aims to determine several genotypes of upright leaf-type maize with high production, in addition to knowing the genotypic characters obtained from the selection of upright leaf-type corn with closer spacing. The study was arranged as an experiment using a randomized block design (RBD) with the treatment of types of corn resulting from crosses. There were 6 genotypes tested, namely SU1, SU2, SU3, SU4, SU5, SU6, and 2 control genotypes namely SU7 (variety RK75) and SU8 (variety RK457). Genotypes were tested based on agronomic characteristics and yield. The results showed that the production of the tested and the control genotypes were not significantly different. However, the highest average production was found in the comparison genotype, especially the RK457 variety, which was 7.49 t/ha. The results of the selection of agronomic characters stated that the genotypes tested and the control genotypes showed no significantly different results on the characters of plant height, cob height, leaf length, leaf width, and leaf angle but significantly different on the stem diameter character. Genotype SU5 had an average stem diameter of 20.75 mm, not significantly different from genotype SU6 (18.95mm), RK457 (19.24 mm), and RK75 (17.79 mm). However, it was significantly different from the genotypes SU1 (16.35 mm), SU2 (14.40 mm), SU3 (16.05 mm), and SU4 (16.93 mm). The selection results for yield characteristics stated that the tested and control genotypes did not have significantly different characters.

Abstract

Demand for poultry products continues to increase. The quality of livestock commodities is obtained by providing good feed (good feeding practices). Feed is the most significant component of production costs, namely 60-70%. Utilizing the potential of local feed ingredients can reduce feed costs and improve livestock health. Herbal administration improves livestock performance through bioactive substances. Herbs used as feed ingredients are turmeric, ginger, and indigoferas leaf meal. Herbal plants function as natural antibiotics, antivirals, and antimicrobials. This study aims to determine the effectiveness of using herbs in feed on production performance. The research location was in Mappesangka Village, Ponre District, Bone Regency, from April to December 2022. The study used a Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatment consisted of basal feed (control), basal feed 97% + herbs 3%, basal feed 96% + herbs 4%, and basal feed 95% + herbs 5%. Each experimental unit consisted of 4 chickens. The strain used was the Novogen strain aged 32 weeks as many as 80 individuals, reared for 28 days. The variables observed were feed consumption, conversion, hen day production, and egg weight. The data obtained were tabulated, then statistical analysis was carried out with ANOVA and Duncan's test. The results showed that the use of herbs had a significant (P<0.05) effect on Hen Day Production (HDP). The results showed that using as much as 3% of herbs could improve laying hens' production performance.
