A novel mutation in TFL1 homolog sustaining determinate growth in cucumber (Cucumis sativus L.)
(Springer-Verlag GmbH Germany, part of Springer Nature, 2020)Determinate and indeterminate growth habits of cucumber can affect plant architecture and crop yield. The TER MINAL FLOWER 1 (TFL1) controls determinate/indeterminate growth in Arabidopsis. In this study, a novel mutation ... -
Nutrient digestibility in diets containing low-phytate barley, low-phytate field pea and normal phytate field pea, and the effects of microbial phytase on energy and nutrient digestibility in the low and normal-phytate field pea fed to pigs
(Elsevier, 2015-05)Five ileal cannulated barrows (43.6 ± 1.3 kg BW) were used in a 5 × 5 Latin square design experiment to determine the apparent (AID) and standardized (SID) ileal digestibility of N and amino acids (AA) in low-phytate field ... -
Nutrient management options for enhancing productivity and profitability of conservation agriculture under on-farm conditions in central highlands of Kenya
(AIMS Agriculture and Food, 2020)Decline in soil fertility is one of the major constraints to sustainable crop production and profitability. To meet the increasing demand for the growing population the issue of low soil fertility needs to be addressed. ... -
Nutritional and microbial quality of extruded fish feeds containing black soldier fly (Hermetia illucens L) larvae meal as a replacement for fish meal for Nile Tilapia (Oreochromis niloticus) and African sharptooth catfish (Clarius gariepinus)
(Taylor & Francis, 2021-05-24)The black soldier fly (Hermetia illucens L.) is a potential substitute of fish meal in feeds. However, information on the nutrition and safety of these feeds is inadequate. This study examined the quality of fish feed ... -
Nutritive value and Palatability rating of fifteen Selected Indigenous Kenyan Browse Species fed to Small East African Goats.
(Livestock Research for Rural Development 29 (6) 2017, 2017-06)A palatability study was conducted using fifteen indigenous multipurpose tree leaf forages offered to twenty intact male Small East African Goats, 7 to 8 months and 18kg ± 2.1kg. The CP (gkg-1DM) of the best five species ... -
Nutritive Value of Bakery Products From Wheat and Pumpkin Composite Flour
(2017)The pumpkin fruit of the species C. moschata Duchesne has great nutritional potential, but remains under-utilized in Kenya. The fruits have diverse health enhancing properties. This vegetable-fruit has potential to be ... -
