“…Globally, groundnut forms an important component of both rural and urban diet through its provision of valuable protein, edible oil, fats, energy, minerals, and vitamins (Ayoola et al, 2012;John et al, 2004;Nagalakshmi et al, 2011). Groundnut is one of the nutritionally rich crops, which can substitute high cost animal-based diets; for instance, groundnuts seed (raw, sundried and roasted) contains 24.70, 21.80 and 18.40% of protein and 46.10, 43.80 and 40.60% of fat, respectively (Ayoola et al, 2012).…”

“…Moreover, it is an important source of vitamins, calcium, and fiber (Ayoola et al, 2012). In addition, groundnut cake is safe, rich in protein, and crude oil and is used in livestock feed (Nagalakshmi et al, 2011) where it increases livestock productivity since groundnut haulm and seed cake are rich in digestible crude protein content (Abiba et al, 2012). Furthermore, as a legume, groundnut fixes atmospheric nitrogen in soil and thus improves soil fertility and saves fertilizer cost in subsequent crops production (Simtowe et al, 2010;Toomsan et al, 1995).…”

This study analyzes the profit efficiency and its determinants in groundnut production, applying a stochastic profit frontier model on survey data collected from 400 groundnut growing households in Malawi. The result indicated that the inefficiencies in groundnut production hindered profitability in the sector. The profit efficiency ranged from 1% to 89% (with a mean of 45%). Significant association was observed between efficiency and both farm specific and institutional factors. Efficiency appeared to be significantly and positively associated with access to extension service (p<0.05), household size (p<0.05) and, soil quality (p<0.000). Distance to the local market from the homestead (p<0.000), and land size (p<0.000) allocated to groundnut production were found to reduce the profit efficiency. Maleheaded households, on the average were six percent more efficient compared to female headed households. The study indicated potential for increasing groundnut profitability by 55% by improving the access to extension services and markets, which underscores the need for increased resource allocation to support the delivery of extension services and to the improvement of market infrastructure for the enhancement of groundnut profitability.

“…The sunflower cake is an excellent source of nutrients for lambs because is composed by oil rich in polyunsaturated fatty acids (65.3%), crude protein content is about 22-33% (NAGALAKSHMI et al, 2011;PEREIRA et al, 2011a), and high dry matter digestibility (65%) (BERAN et al, 2007). As all vegetable oils, sunflower oil essentially consists of triglycerides (98 to 99%), low linolenic acid content and high linoleic acid content, the changes that occur in the concentration and composition of fatty acids arise from the varieties, climate change during its cultivation and degree of maturity (PEREZ; CARELLI;CRAPISTE, 2004).…”

Sunflower cake in diets for lambs: intake, digestibility, nitrogen balance and rumen parameters

et al. 2015

The present study objective was to determine the intake and digestibility, nitrogen balance and ruminal fermentation parameters in sheep fed diets containing levels of substitution of soybean meal for sunflower cake. The diets consisted of five levels of protein soybean meal (0, 25, 50, 75 and 100 %) by sunflower cake. Diets were formulated with 12.6% CP, respecting the roughage:concentrate ratio of 40:60, as source roughage was used hay Tifton-85 and as food concentrates used were: corn, soybean meal, sunflower cake and premix mineral vitaminic. Five lambs crossbred castrated with average weight of 29.64 ± 2.94 kg were used, distributed in latin square 5 x 5. There were no differences in intake dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and total digestible nutrients. The intake of ether extract (EE) and non-fiber carbohydrates (NFC) were increased linearly. For intake of total carbohydrates (TC) was observed equation linear in relation to body weight and metabolic weight and quadratic when expressed in g day -1 with peak in 377.1 g kg -1 replacement of soybean meal by sunflower cake. There were no differences in digestibility DM, OM, CP, NDF, NFC and TC. There was a linear increase in the digestibility of ether extract (EE). The intake, feces, urinary and retained nitrogen were not influenced by levels of substitution of soybean meal by sunflower cake in the diets. For the pH of liquor ruminal there was no difference for the different levels of substitution of soybean meal by sunflower cake. However, ruminal pH differed with respect to collection time for all experimental diets. There was no effect on diets and sampling time for concentration of NH 3 -N. It was concluded that the sunflower cake can be used as an alternative food to replace soybean meal up to 100% in concentrate mixture unless there are changes in the rumen parameters, balance of nitrogen, intake and nutrient digestibility.

Os tratamentos consistiram em cinco níveis de substituição da proteína do farelo de soja (0; 25; 50; 75 e 100 g kg -1 MS) pela torta de girassol. As rações foram formuladas com 12,6% PB respeitando-se uma relação volumoso:concentrado de 40:60, tendo como fonte volumosa o feno de Tifton-85 e ração suplementar formuladas com milho, farelo de soja, torta de girassol, mistura mineral e vitamínica. Foram utilizados cinco borregos sem raça definida, castrados, com peso vivo médio de 29,64 ± 2,94 kg, distribuídos em quadrado latino 5 x 5. Não houve diferenças nos consumos de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), fibra em detergente neutro (FDN) e nutrientes digestíveis totais (NDT). O consumo de extrato etéreo (EE) e carboidratos não fi...

“…Another such material available in abundance is Karanja (Pongamia pinnata), widely distributed throughout tropical Asia and the Seychelles Islands, South East Asia, Australia, and India (Prajapati et al 2003). In many parts of the world, production of Karanja for industrial (biodiesel) and medicinal purposes is gaining popularity (Nagalakshmi et al 2011). Pongamia pinnata, belonging to the family Leguminosae, is a prominent species having nonedible oilseed that can be grown easily in available wastelands.…”
