Feeding flaxseed to dairy animals improve milk production and reproductive performance. So, the objective of our study was to investigate effect of inclusion flaxseed in Damascus goat's ration on its reproductive performance. Twenty-four Damascus goats (31.40 ±0.50 kg weight and 2-3 years old) were divided into three groups (randomly, eight animals each). The basic diet of control group (T1) consisted of 56.67% concentrate feed mixture (CFM) and 33.33% Alfalfa hay, while the groups T2 and T3 supplemented with 10% full fat soya, 5% flaxseed + 5% full fat soya and 10% flaxseed, respectively. Inclusion flaxseed in goat's ration at rate of 5 and 10% resulted in significant increase in all nutrients digestibility, except nitrogen free extract digestibility (NFE) as well as the nutritive values as total digestible nutrients (TDN). Dry matter intakes (DMI) of the different experimental groups were comparable. Goats in T3 recorded the highest does conceived, twinning, conception and kidding rates % as well as total kids born, than other groups (T1 and T2). On the hand T3 recorded the lowest aborted does and barren does (Zero) compared to T1 and T2. Animals of T3 recorded significant higher of total protein, globulin, Albumin and urea concentration than T1 and T2. Concerning lipids profile, the animals of T3 recorded significant lower triglycerides, cholesterol and Low-density lipoprotein concentration than those of T1 and T2. While the animals of T3 recorded significant higher High-density lipoprotein concentration compared to T2 and T1. The body weight of does is not significantly affected by any of three treatments. In conclusion, flaxseed supplementations in Damascus goat's diets during the gestation period lead to improve total tract digestibility, reduced blood lipids and normalize renal and hepatic functions and improved its reproductive performance, especially those fed on diets containing 10% flaxseed.

growth trail was carried out to determine the effect of feeding rations with different levels of concentrate: roughage ratio on rumen development through examining the rumen fermentation and the identification and density of rumen ciliate protozoa for sequence five months. Eighteen early weaned Balady male goats with an average live body weight about 7.58 kg at 60 days age were randomly allocated in three groups (6 lambs each) according to body weight. The three groups were fed starter pelleted consists of different concentrate: roughage ratios (T1; 90:10, T2; 80:20 and T3; 70:30). Results showed that rumen parameters concentration and ruminal ciliate protozoa count were significantly increased (P≤0.01) from the age of 8 weeks till the age of 24 weeks. Also, the data indicated that ruminal pH values and ruminal ciliate protozoa count were higher (P≤0.01) before feeding then it decreased at 3 hours post feeding followed by gradually increased, although total volatile fatty acids, ammonia nitrogen, non-protein nitrogen, total nitrogen and true protein nitrogen concentrations reached the highest (P≤0.01) value at 3hr post-feeding then decreased gradually. Seven species of ruminal protozoa were identified in this study, Entodinum spp was the most dominant specie. Comparison among the three experimental treatments showed that T3 had the highest (P≤0.01) concentrations of rumen parameters and ruminal ciliate protozoa count during the whole period followed by T2, while T1 had the lowest (P≤0.01) values. So we recommended involving high roughage ratio in goat kids feeding.

Thirty weaned Barki lambs with average body weight 27.56±0.57 kg were blocked by weight and randomly distributed into three equal groups to investigate the impact of feeding trimming waste of mandarin trees (TWMT) on productive performance of lambs. The first group of animals was fed with Berseem hay (BH) plus concentrate feed mixture (CFM) without any additives and kept as a control ration (CR). The second group was fed TWMT plus CFM as untreated ration (UR), where, the animals in group three received TWMT plus CFM supplemented with Bio-Magic with level 10kg fresh matter/ton CFM and kept as a treated ration (TR). Feed was offered as 70% CFM of the total requirements for growing lambs and the roughage was offered ad lib. The results were summarized as follows:-CR group had higher digestibility than other groups. Sheep fed TR ration revealed lower TDN compared to the other groups. The DCP was significantly higher for UR and TR than CR-The CR group recorded the lowest value of Nretained however no significant differences were recorded between UR and TR groups. -The ADG for TR group increased by 4% and 15.9% compared to CR and UR, respectively.-Feed conversion was the best for lambs fed TR, while UR recorded the worst value.-The best economic efficiency recorded by TR. -It may be concluded that, TWMT has the potential solve to reduce shortage of roughage feeds for animals in Egypt; furthermore reducing feed cost under desert conditions.
