The incidence of twins and/or multiple births in 20 heads of young Etawah-cross does was studied following oestrous synchronization using intravaginal sponges containing 60 mg medroxyprogesterorle acetate (Repromap) for 15 days . Twenty four hours priorto sponges withdrawal, the does were injected with pregnant mare serum gonadotrophin (PMSG) at dose rates of 0 (Group A), 10 (Group B), 15 (Group C) and 20 iu/kg (Group D) body weight. Amature buck fitted with an apron was used to detect the onset of oestrus at every four hours. The oestrous doe was naturally mated twice, 12 hours after onset of oestrus and 10 hours later. About 3-5 days after oestrus, all does were subjected to mid-ventral laparoscopy to detect ovulation rate . Two months after mating all does were subjected to pregnancy test using diagnostic ultrasonography. Results showed that all does exhibited clear sign of oestrus. The onset of oestrus occurred 15-43 hours after sponges withdrawal or 39-59 hours after PMSG injection. Does injected with PMSG (Groups B, C and D) showed oestrus 16-21 hours earlier (P<0.05), and it was 1 .6-4.8 hours longer (P>0 .05) than that of control (Group A) . However, there was no significant differences among the PMSG-treated groups . Ovulation rates increased from 1.0 in Group Ato 1.8 in Group B and 2.6 in bah Groups Cand D. Average litter size in Groups A, B, C and D were 1.0, 1.8, 2.4 and 1.0, respectively. It was concluded that injection of 15 iu PMSG/kg body weight gave the best result for increasing litter size in young Etawah-cross does .

An experiment was designed in order to study the crude protein and energy requirement of Ettawah Cross growing goats. Twenty seven kids (average body weight of 11.80 + 1.4 kg) were used and randomly allotted to a 3 x 3 factorial arrangement of treatments, consisting of three different levels of crude protein and three levels of energy. Results from this experiment showed that animal performance was effected by dietary treatments. Increasing levels of energy ration significantly (P<0.05) decreased the dry matter intake, with overall mean values were 3.0; 2.8 and 2.5% of body weight for low, medium and high levels of energy respectively. Dietary treatments increased energy (EM) and crude protein intake, and overall values were 0.2046 + 0.016 Mkal/kg BW0.75 and 8.20 + 2.473 g/kg BW0.75 repectively. Positive response on animal performance was also effected by dietary treatment, with overall mean value of 86.40 + 29.59 g head-1day-1. The highest response on animal performance (ADG 123.3 g) was found on kids fed diet containing combination of low level of energy and high level of crude protein. Meanwhile, the lowest average daily gain (45 g) was resulted by kids fed ration containing combination of high level of energy and low level of crude protein.

The objective of this study is to determine the best concentration of lactose in Tris extender in maintaining liquid semen viability of Saanen bucks stored at 5Â°C. Four heads of Saanen bucks of 2-4 years old were used as semen source. Semen was collected once a week using an artificial vagina. Variance analysis was conducted based on completely randomized design with three treatments, i.e 30, 60, and 90 mM lactose (L30, L68 and L90). Duncan test was used to observe the different between treatment. Results indicated that the mean percentage of motility, live sperm, intact plasma membrane, and intact acrosomal cap of liquid semen in treatment L30 (70.83; 78.20; 79.56 and 81.20% respectively) were significantly higher (P<0.05) than treatment L60 (67.08; 73.73; 75.01 and 76.87% respectively) and treatment L90 (61.50; 71.88; 69.08 and 71.33% respectively). After storage for 48 hours at 5Â°C apparently the mean percentage of motility, live sperm, intact plasma membrane and intact acrosomal cap in treatment L30 were significantly higher (P<0.05) than those of in treatment L60 and L90. Decreasing percentage of motility, live sperm, intact plasma membrane, and intact acrosomal cap during storage at 50C from 0 until 48 hour in treatment L30 (42.83; 19.75; 40.84 and 39.00% respectively) were significantly lower (P<0.05) than those of in treatment L60 (55.41; 23.06; 50.14; and 50.90% respectively) and treatment L90 (54.83; 29.93; 50.14 and 50.97% respectively).

Bucks semen is easily damaged compared to bull semen during cryopreservation process. Consequently, frozen semen quality decrease especially motility, live sperm, intact plasma membrane, and intact acrosomal cap after thawing. Objectives of this research was to evaluate the effect of egg yolk concentration in Tris extender with and without seminal plasma in maintaing frozen semen quality of Saanen buck. Four heads of Saanen buck of 2-4 years old were used in this experiment. Semen was collected once a week using artificial vagina. Experimental design applied was factorial complete random desing 2x2, viz. A factor was seminal plasma (A1 = with seminal plasma and A2 = without seminal plasma), and B factor was concentration of egg yolk (B1 = 10% and B2 = 20%). Duncan test were applied to identity differences between treatment. Result of these study indicated that the mean percentage of motility (M), live sperm (LS), sperm with intact plasma membrane (IPM) and intact acrosomal cap (IAC) after dilution and equilibration were not significantly different (P>0.05) in all treatment. After thawing, the mean percentage of M, LS sperm with IPM and IAC in A1 treatment (41.43, 51.52, 56.63 and 50.35% respectively) were significantly higher (P<0.05) than A2 treatment (37.14; 48.67; 52.31 and 45.09% respectively). Likewise, the mean percentage of M, LS, sperm with IPM and IAC in B2 treatment (41.79; 51.32; 55.78 and 49.50% respectively) were significantly higher (P<0.05) than B1 treatment (36.79, 48.86; 53.16 and 45.94% respectively). There were a significant interaction between factors of seminal plasma and concentration egg yolk in Tris extender, where the increase of egg yolk concentration from 10% to 20% in unwashed seminal plasma treatment caused increase in percentages of M, LS, sperm with IPM and IAC. On the other hand in washed seminal plasma treatment there were a trend of decreasing frozen semen quality. It is concluded that the combination of 20% egg yolk in Tris extender with seminal plasma is effective in maintaining frozen semen quality of Saanen bucks.

Digestibility of ruminant feeds is greatly determined by ruminal fermentation which in turn is greatly affected by micro-ecology of the rumen. Manipulation of micro-ecology such as supplementing with various yeasts or micro elements could improve digestibility of the feed. The effect of Comin+ (R1) and Zn-biocomplex (R2) alone or their combination (R3) on performance of Ettawa Crossbred kids, fed concentrate containing Aspergillus oryzae (R0) was studied. Twenty four Ettawa Crossbred kids (6-8 month of age; initial liveweights =16.63Â±2.10 kg) were divided into 4 groups. Feeds given were King grass (Pennicetum purpuroides) ad libitum and concentrate. The observations were carried out for 16 weeks with 2 weeks adaptation period and the experiment was conducted in a completely randomized design with 4 treatments and 6 replications. The results showed that supplementations significantly (P < 0.05) increased total DM intakes from 685 g/d (R0) became 748, 711 and 858 g/d; and grass DM intakes from 304 g/d (R0) became 373, 331 and 479 g/d for R1, R2 and R3, respectively. Digestibilities of DM, NDF and DE/GE were not affected by supplementation, but supplementations significantly (P < 0.05) affected digestibilities of ADF and CP. Supplementation also significantly improved (P < 0.05) ADG from 65.18 g/d (R0) became 94.64, 83.04 and 90.77 g/d; and FCR from 10.51 (R0) became 7.82, 8.36 and 9.46 for R1, R2 and R3, respectively. It was concluded that supplementation of Comin+ (R1) gave the best growth performance of Ettawa Croosbred goats, where ADG and FCR improved by 45.20% and 34.40%.

An experiment was caried out to study the protein requirement for Etawah cross breed. Thirty Etawah cross breed does were used in this study (average body weight 37.6+3.5 kg) and randomized to obtain one of three treatments. The treatments were the protein content of concentrate supplement. The protein levels were R1 (CP 16%), R2 (CP 22%) and R3 (CP 26%). The concentrate supplements were offered during late pregnancy and early (first 3 months) lactation period. The study showed that dry matter intake during pregnancy and early lactation period was not affected by treatments. The highest average daily gain during late pregnancy reached by R3 (66.45 g/day) which was not significantly different with R2 (61.9 g/day) and R1 (48.8 g/day). The highest total birth weight per does was achieved by R2 (6.05 kg). Average daily milk production was not affected by treatment. The production at first week of lactation was 1,044.5 g/day and decreased to 466.7 g/day in week 11. R2 produced the highest average daily gain (107.8 g/day) preweaning per does, while R1 and R3 was 84 and 84.4 g/day, respectively.

The effect of continuous feeding of gliricidia on reproduction and production performances in second breeding of Javanese Fat-Tailed (JFT) sheep through the second breeding period was studied. Twenty six ewes post lactation at first lambing (body weight 22.5-26.5 kg) were divided into four treatment groups. Each group consisted of 6 animals except Group D had 8 animals. They were given King grass (Pennisetum purpureophoides) and gliricidia (Gliricidia sepium Jacq.) leaf with ratio of 100:0 (Group A = control), 75:25 (Group B), 50:50 (Group C) and 0:100 (Group D). Forages were given 2.5-3% (dry matter) of liveweight. All groups were supplemented with 100g/head/day concentrate (crude protein = 16%), but during late pregnancy and lactation they were supplemented at 200 g/head/day. Results showed that feeding gliricidia 25-100% of total forages improved body weight due to the increasing protein intake. The maximum concentration of progesteron increased from 0.81 to 2.78 ng/ml. The ovulation rate and prolification also increased significantly (P<0.05) from 1.6 to 3.0 and 1.33 to 2.38, respectively. Individual birth and weaning weights of the lambs were not affected. It is concluded that feeding gliricidia continuously up to 100% as forages and supplemented with concentrate gives positive effect on bodyweight gain, reproduction and production performances in second breeding of JFT sheep.
