Effect of dry fat supplementation on productive and reproductive performance of Damascus goats
Abstract: This study was conducted to investigate the effect of dry fat supplementation on digestion coefficients and rumen fermentation activities, reproductive parameters, some blood components and milk yield, of Damascus goats.
Forty five Damascus goats3-4 years of age 57 Kg average body weight and 2-3 parities were selected randomly and divided into 3 similar groups of 15 goats in each with a I' completely randomized design .Trial started 45 days before kidding and 90 days after kidding. Experimental rations were offered to animals with rate of 0, 3 and 5% dry or protected fat (DF) (based on DM intake). The basal ration composed of concentrate feed mixture(CFM) : roughage { berseem 3rd cuts+ rice straw (RS) (60:40%)}. Digestibility trial was carried out using nine Damascus bucks with average 60 kg BW and aged 2.5-3 years.
Data showed that higher (p<0.05) digestibility of DM, OM, EE and NFE digestibility coefficients were optimal for the tested groups than control. Rumen parameters (pH, total VFA and ammonia-N) were higher in supplementing groups than control. Concentrations of blood plasma total protein, glucose, total lipids and total cholesterol of does were higher supplemented groups than control one. Dry fat supplementation had no effect on Inception rate and had effect on litter size and twining rate as well as kids birth and weaning. weight. Milk yield was higher in supplemented groups than control as well as its Imposition (fat, total solids and solids not fat % ).
Generally, it concluded that dry fat supplementation in ration of Damascus goats improved , daily gain. feed efficiency and digestibility as well as higher some traits of reproductive performance.
