“…Therefore, the increased concentration of CP, IVOMD, and ME during the dry season could potentially compensate for reduced forage biomass as reflected by relatively lower TDW and higher LSR in the dry season. However, it should be noted that our findings are not in agreement with the results of Reference [49], who reported a decline in CP, IVOMD, and ME values and an increase in NDF, ADF, and ADL in the dry season. These differences might be attributed to the phenological differences of plants at time of harvest.…”

The evaluation of forage crops for adaptability and performance across production systems and environments is one of the main strategies used to improve forage production. To enhance the genetic resource base and identify traits responsible for increased feed potential of Napier grass, forty-five genotypes from Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), Brazil, were evaluated for forage biomass yield and feed nutritional quality in a replicated trial under wet and dry season conditions in Ethiopia. The results revealed significant variation in forage yield and feed nutritional qualities among the genotypes and between the wet and dry seasons. Feed fiber components were lower in the dry season, while crude protein, in vitro organic matter digestibility, and metabolizable energy were higher. Based on the cumulative biomass and metabolizable energy yield, top performing genotypes were identified that are candidates for future forage improvement studies. Furthermore, the marker-trait association study identified diagnostic single nucleotide polymorphisms (SNP) and SilicoDArT markers and potential candidate genes that could differentiate high biomass yielding and high metabolizable energy genotypes in the collection.

“…Browse species on the other hand have a higher crude protein content, lower fibre and are more digestible compared to the grasses and crop residues (Evitayani et al . 2004 ). Browse species therefore provide a better feed resource during the dry season in areas where they are available.…”

Characterization of the goat feeding system among rural small holder farmers in the semi-arid regions of Uganda

Goats (Capra hircus) are widely distributed in Africa and Asia, and are important to the subsistence and economic livelihoods of many people in these areas. The goat feeding system among rural small holder farmers in Buyende district (Uganda) was characterised by determining the goat rearing practices, feed resources fed on by goats and availability of browse species mentioned by small holder farmers. Data was gathered using ethnobotanical and ecological approaches. Results from the ethnobotanical survey revealed that farmers were rearing indigenous goat breeds that are managed by tethering in natural pastures during the rainy season but free ranging during the dry season (i.e. when no crops are susceptible of damage). Major challenges facing goat production in the study area were diseases, shortage of land and inadequate pastures. The reduction of grazing land due to crop farming, has led to tethering of animals which in turn leads to restricted feeding. Goats were known to feed on 48 plant species distributed in 18 families and 39 genera dominated by trees and shrubs. Browse species were known to stay longer in the dry season when the grass and herbaceous species were no longer available. The most frequently mentioned browse species were Ficus natalensis, Harrisonia abyssinica, Acalypha psilostachya, Artocarpus heterophyllus and Lantana camara while Panicum maximum and Impeata cylindrica were the most mentioned herbaceous species. 31 browse species were encountered in the ecological survey. These were dominated by Combretum molle, L. camara, A. zygia, M. indica, and Albizia coriaria. In conclusion, the rearing practices of goats in Buyende district are comprised of indigenous goats tethered in natural pastures especially browses which stay longer through the dry season. However, most of the preferred browses are rare according to the computed IVI (i.e. less than 30%).

“…Cynodon, Pennisetum and Brachiaria. Evitayani et al (2004a) stated that dry matter digestibility of grass on rainy seasons is higher than that in dry seasons. Legume forage contained higher amounts of crude protein but lower fiber content (NDF and ADF), resulting in higher digestibility compared to grass (Evitayani et al, 2004b).…”

Abstract. Indonesia is a country that has a lot of limestone mountains, covering 15.4 million hectares. Limestone mountains have strategic functions as limestone is used as building materials and as raw material in cement industry. Therefore, limestone mining quarry in various areas of limestone mountains in Indonesia is increasingly widespread. The biggest negative impact of limestone mining is the formed open land which is abandoned and unutilized. Changes in the ecosystem will lead to the reduced levels of diversity and productivity of indigenous forage which will ultimately reduce the performance and development of ruminants livestock kept by farmers in the mountainous region of limestone. This study aims to determine the diversity and productivity of indigenous forage on former limestone mining quarry in limestone mountains of southern Gombong. The research was conducted through survey by identifying and measuring the forage production of sample plots assigned purposively. Location of the study was divided into three categories, mild, moderate and heavy mining. Results showed that soil fertility levels in open fields of former limestone mining in southern Gombong mountains are low with total N content of 0.049 -0.141%, total P2O5 of 0.067 -0.133% and total K2O of 0.086 -0.100%. The diversity of indigenous forage on mild mining was more diverse than that of moderate and heavy mining, i.e. 13 species comprising 7 grass species, 2 legumes species, and 4 species of shrubs. The most dominant species in all mining categories are Cynodon dactylon, Imperata cylindrica, Ageratum conyzoides and Mikania micrantha. The results also showed that in the open land of mild mining had the highest production of fresh and dry matter compared to that of moderate and severe mining.

Pegunungan kapur memiliki fungsi yang sangat strategis karena batuan kapur banyak dimanfaatkan sebagai bahan bangunan dan bahan pembuatan semen. Oleh karena itu usaha penambangan batu kapur di berbagai wilayah pegunungan kapur di Indonesia semakin berkembang luas. Dampak negatif terbesar dari usaha penambangan batu kapur adalah terbentuknya lahan terbuka yang terlantar dan tidak didayagunakan. Perubahan ekosistem tersebut akan menyebabkan menurunnya tingkat keragaman dan produktivitas hijauan pakan indigenous yang pada akhirnya akan menurunkan tingkat kinerja dan perkembangan ternak ruminansia yang dipelihara oleh peternak di wilayah pegunungan kapur. Penelitian ini bertujuan untuk mengetahui keragaman dan produktivitas hijauan pakan indigenous pada lahan bekas penambangan kapur di pegunungan kapur Gombong selatan. Metode yang digunakan adalah metode survei dengan melakukan inventarisasi dan pengukuran produksi melalui petak contoh secara purposive. Lokasi penelitian terbagi dalam tiga katagori yaitu penambangan ringan, sedang dan berat. Hasil penelitian menunjukkan bahwa ...
