Abstract

A study was conducted to determine the influence of different particle size limestone in layer diets on egg production and eggshell quality during the later stages of egg production (>54 weeks of age). Calcitic limestone (360 g Ca/kg), consisting of small (<1.0 mm), medium (1.0 - 2.0 mm) and large (2.0 - 3.8 mm) particles were obtained from a specific South African source that is extensively used in poultry diets Isoenergetic (14.32 MJ AME/kg DM) and isonitrogenous (172.01 g CP/kg DM) diets with a dietary Ca content of 39.95 g Ca/kg DM were used. Sixty nine, individual caged Lohmann-Silver pullets, 17 weeks of age, were randomly allocated to the three treatments (n = 23) for the determination of various egg production and eggshell quality characteristics. Egg production and eggshell quality data recorded on individual basis at 54, 58, 64 and 70 weeks of age were pooled to calculate and statistical analysed parameter means for the late production period. Different limestone particle sizes had no effect on any of the tested egg production and eggshell quality parameters. These results suggested that larger particles limestone are not necessarily essential to provide sufficient Ca2+ to laying hens for egg production and eggshell quality at end-of-lay, provided that the dietary Ca content satisfies the requirements of the laying hen.

Pengaruh Penambahan Zeolite pada Kualitas Telur Puyuh

PENGARUH PENAMBAHAN ZEOLIT DALAM RANSUM TERHADAP KUALITAS TELUR BURUNG PUYUH [The Effect of Zeolit Addition in the Ration on Egg Quality of Quail (Coturnix coturnix japonica)]

Journal of the Indonesian Tropical Animal Agriculture, 31 (1). pp. 28-31. ISSN 0410-6320



Abstract

ABSTRAK Sebanyak 125 ekor burung puyuh (Coturnix coturnix japonica) telah digunakan untuk mengkaji pengaruh pemberian zeolit dalam ransum terhadap kualitas telur. Burung dialokasikan sesuai rancangan acak lengkap dengan lima perlakuan, lima ulangan dan masing-masing ulangan terdapat lima ekor burung puyuh. Perlakuan yang diberikan adalah penambahan zeolit pada ransum basal pada masing-masing perlakuan yaitu T0 (0%), T1 (2,5%), T2 (5%), T3 (7,5%) dan T4 (10%). Kualitas telur yang diamati adalah berat telur, persentase berat kerabang, persentase berat kuning telur, persentase berat albumen, tebal kerabang, indeks kuning telur, dan indeks albumen. Hasil penelitian menunjukkan bahwa penambahan zeolit pada ransum basal sampai level 10% secara umum tidak memberikan pengaruh yang signifikan, tetapi penambahan zeolit sampai level 7,5% akan memberikan pengaruh berbeda pada peningkatan tebal kerabang telur. Kata kunci : zeolit, ransum, telur, burung puyuh ABSTRACT A hundred and twenty five quail (Coturnix coturnix japonica) have been used to study the effect of zeolite addition in a ration on quail eggs quality. The birds were allotted to a completely randomized design, with five treatments, five replications and each replication contained five quails. The treatments were T0 (0%), T1 (2.5%), T2 (5%), T3 (7.5%) and T4 (10%). The parameters of egg quality observed were egg weight, egg shell weight, yolk weight percentage, albumen weight percentage, eggshell thickness, yolk index and albumen index. The results showed that zeolite addition in the ration up to 10% did not significally affect overall egg quality, though the zeolite addition up to 7.5%. eggshell thickness.

Agriculture Conditions using Zeolite

Raw material zeolite from Sukabumi mining

ENHANCING OF GROWTH, ESSENTIAL OIL YIELD AND COMPONENTS OF YARROW PLANT (Achillea millefolium) GROWN UNDER SAFE AGRICULTURE CONDITIONS USING ZEOLITE AND COMPOST

ABSTRACT

The unique cation exchange, adsorption, hydration-dehydration and catalytic operties of natural zeolites (as granules) loaded with micronutrients, have promoted their use in clean agriculture as soil amendments and slow-release fertilizers. This research was conducted in open field to investigate the effects of natural zeolite, organic fertilizer (compost) and combination of them on herb growth, oil yield and components of Yarrow plants (Achillea millefolium). The results indicated that zeolite loaded with micronutrients mixed with organic fertilizer led to significant increase in fresh weight, dry weight,number of flowers, total chlorophylls, carbohydrates content, oil yield as well as major ingredients of essential oil, and mineral nutrients, in comparison with the recommended dose of chemical fertilizers NPK (control) under the same conditions. These results undoubtedly confirm that zeolite and organic fertilizer (compost) mixture could replace the application of chemical fertilizers and consequently improve the quality and quantity of Achillea yield. This application may have direct impacts on safety and efficacy of herbal active constituents which entail for medicinal and aromatic products. Besides minimizing economic costs and pollution of agricultural environment.

Key words: Achillea millefolium , chemical fertilizers, organic fertilizer, yarrow plant , zeolite.
