Abstract/ Executive Summary:

Three different complete compound pellets containing different levels of energy and crude protein, viz. standard energy and protein (SEP),low energy and protein(LEP) and high energy and protein (HEP) were prepared where SEP contained 10.28 MJME and 140g CP per kg DM of feed, LEP contained 10% less energy and protein and HEP contained 10% high energy and protein than SEP, respectively and were fed to three groups of growing Black Bengal goats to evaluate feeding value of different levels of ME and CP containing pellet. Data were analyzed using the general linear model (GLM) procedure of statistical analysis software (SAS). The effects of different level of energy and protein containing pellet on performance of goat were different. Highest energy (ME)and crude protein intake and best FCR, PCR and total live weight gain were observed in HEP but SEP and HEP showed significantly higher (p<0.01) values of the parameters than LEP and only HEP showed significantly higher (p<0.05) crude protein intake (Kgd-1 100-1Kg LW and gKg-1 W 0.75 d -1 ) and MEI (MJd-1 100-1Kg LW and MJ Kg-1 W 0.75 d -1) than LEP. Both SEP and HEP groups showed significantly higher (p<0.01) digestibility of CP than LEP. On the other hand, HEP showed higher (p<0.01) digestibility of DM and OM than both SEP and LEP but digestibility of EE was higher (p<0.01) in SEP than LEP and HEP. Digestibility of NFE was dissimilar in three groups and the difference was significant (p<0.01) where highest value was found in HEP. Dissimilar percentage of digestible value of CP, NFE and D values were observed among the groups where HEP showed highest value (p<0.01) and LEP showed lowest. Percent of digestible value of CF was higher (p<0.01) in LEP than SEP and HEP. On the other hand SEP and LEP showed higher (p<0.01) value of EE than HEP where as SEP and HEP showed higher (p<0.01) value of TDN than LEP. Meat yield, selling price of meat, and total price was highest in HEP but both SEP and HEP showed significantly higher (p<0.01) value of these parameters than LEP. Feed cost and total rearing cost was highest in HEP but the values were dissimilar among the groups and the difference was significant (p<0.01). Insignificantly highest net profit was observed in SEP and lowest in LEP. From the observation it can be concluded that there is a positive effect of increasing energy and crude protein in diet on performance of goat but economically not significant and in this case standard energy and crude protein containing diet can be used for commercial goat production in stall feeding.

Commodity: Goat, Feed

Objectives:

Estimation of optimal dietary energy and crude protein levels for efficient utilization of nutrients is essential to understand the nutritional requirements for growth. The aim of this work was to investigate the effects of feeding different levels of dietary energy and crude protein in compound pellet on performance of Black Bengal goat and determine the suitable one which is more profitable in stall feeding system of goat production

Methodology:

2.1 Processing of feed ingredients Napier grass (Pennisetum purpureum), cultivated in fodder field of Animal Nutrition Department of Bangladesh Agricultural University, was selected as basal feed and cut, chopped and sun dried. The chopped grass was placed in electric drier for uniform drying, ground in electric grinder using 1mm diameter sieve. Maize, wheat, wheat bran, rice polish, mustard oil cake, soybean meal and molasses were purchased from local market with proper attention so that they are free from dust, fungus and any other extraneous materials. The sample of grass and other feed ingredients were analyzed for proximate components before using for pellet preparation.

2.2 Preparation of compound pellet Three types of compound pellet, viz. standard energy and protein (SEP) contained 10.28 MJME and 140g CP/kgDM of feed (treated as control), low energy and protein (LEP) contained 10% less energy and CP and high energy and protein (HEP) contained 10% higher energy and CP than SEP, respectively, were prepared and properly stored for the goats belonging to three different groups with ground Napier grass and concentrate mixture at the ratio of 60:40.

Achievement/Findings:

Inclusion of high energy and protein in compound pellet diet improved growth performance of goat significantly but the economic assessment was not significant. On the basis of economic point as profit was insignificantly highest in standard energy and protein-containing dietary group. So standard compound pellet diet can be used for commercial goat production install feeding.
