  Problems statement: The level of uterine Secretory-IgA (S-IgA) and numbers of plasma cells was measured to observe the differences between two stages of estrous cycle (follicular and luteal phase) in the healthy cycling non pregnant ewes. Approach: Twelve ewes were used in this study and they were divided into two groups of 6 animals each according to the stages of estrous cycle. All ewes were subjected to estrous synchronization and allowed to undergo one natural estrous cycle after the removal of the sponge. All animals were then slaughtered at the end of the experiment. The uterine mucus was collected by flushing with a mixture of protease inhibitor cocktail in distilled water. For both stages, the level of uterine S-IgA was quantified by using ELISA and Methyl Green Pyronine staining was used to observe the plasma cell in the tissues of the uterine horn and oviduct of ewe’s genital tract. Results: The results were analyzed by independent sample t-test and presented as mean±SEM. This study showed the relationship of the estrous cycle stages to uterine S-IgA concentration (µg mL-1) and populations of plasma cell in the healthy non-pregnant cycling ewes. The concentration (µg mL-1) of S-IgA (0.20±0.01) in the follicular phase was highly significant (p<0.01) as compared with the luteal phase (0.17±0.002). In addition, the populations of the plasma cells were significantly higher (p<0.01) in the uterine horn (4.97±0.32) and oviduct (3.82±0.33) during follicular phase compared to the luteal phase (3.87 ±0.30) and (1.90±0.21), respectively. Conclusion: The main reason for the immunosuppression during the luteal phase did not fully justified, especially with the presence of potential acquired infection during coitus in the follicular phase and at the same time immune system should decrease accordingly to prevent newly attached fetus rejection by the mother immune system.

  The present study was designed to evaluate and compare the natural coral and Calcium Phosphate Cement (CPC) post-implantation in sheep femoral bone. Twenty one adult, male sheep (weight 15-20 kg) were used in this study and were divided into two groups. Group one consists of 12 animals and implanted with natural coral while group two consists of 9 animals and implanted with CPC material. The large cortical defect (2.5x0.5x0.5 cm) was created surgically on the left proximal femur and replaced by the implant. Radiographs and ultrasonographs were obtained immediately after surgery and at 2, 4, 8 and 12 weeks post-implantation. Both ultrasonographs and radiographs taken at 8 and 12 weeks showed that the implants had been resorbed and left the space that much reduced in size. There was no sign of implant rejection observed in all animals. The sheep were euthanased at 2, 4, 8 and 12 weeks post-implantation and the bone examined grossly. Samples of the implant were taken for histological examination. Microscopically, natural coral exhibited rapid resorption and progressively replaced by new bone. At 8 weeks post-implantation, there was no more coral implant present and by week 12 the implant site was almost completely closed and filled by mature bone. Meanwhile, CPC implant was clearly seen and demonstrated only marginal bone formation at the end of 12 weeks study. The coral implant exhibited good bone substitute, but it has fast resorption rate. Thus, it may suitable for less compact bone with small defect.

  Recently, feeding animals with dietary essential fatty acids have become of interest in animal nutrition. This is mainly to enrich their content in animal products in order to improve consumer health. Most of these studies have been focused in sheep and cattle while goats received a little attention. This study was conducted to assess effects of feeding different levels of linseed as a source of n-3 fatty acid on goat’s growth performance, apparent digestibility and carcass characteristics. Twenty-four 5-month old crossbred Boer bucks were divided into three groups (n = 8) and assigned into three treatment diets differed in level of linseed for 110 days. The diets were L0, L10 or L20 contained 0% (control), 10 and 20% (w/w) linseed, respectively. In the last 14 days of the trial, four animals from each group were placed in metabolic crates for collection of feces. At the end of the trial all goats were slaughtered. The results showed that the final weight, total weight gain and apparent digestibility were not affected by the treatments (p>0.05). Goats fed L20 diet had lower (p<0.05) feed intake (669.30 g day-1) compared to L0 (705.21 g day-1) or L10 (698.51 g day-1). The gain: Feed ratio was higher (p<0.05) in L20 compared to other treatments. The internal fat weight was heavier (p<0.05) in L20 (550.57 g) compared to L10 (373.00 g), while in L0 was (469.40 g) without significant difference from both. The percentage of lean was better (p<0.05) in L10 (67.82) compared to L0 (65.25) or L20 (64.78). It is concluded that linseed can be included to goat diets up to 20% (w/w), without adverse effects on growth and carcass quality of goat. Feeding goat 20% linseed can increase feed efficiency while 10% can improve goat carcass traits.

  This study was conducted to investigate the effect of Solid State Fermented Feed (SSFF) with and Without Prepared Probiotic (PP) on the live body weight, weight gain, feed intake and feed conversion ratio of a local Malaysian chicken (Akar Putra). A total of 96 day-old Akar Putra chicks, were randomly assigned to four dietary treatments (24 chicken/treatment), with 3 replicates for each (8 chicken/replicate). The four dietary treatments were the control T1 (no supplement), diet supplemented of SSFF with probiotic in the second treatment was prepared at the rate 1:1:1 (1 kg of commercial broiler feed+1 L tap water+1g PP). While the rate was 1:1:2 (1 kg of commercial broiler feed+1 L tap water+2 g PP) in the third treatment. The chickens in fourth treatment were fed on SSFF without probiotic. The feeding mixtures of T2, T3 and T4 were placed in a plastic tray which closed ad incubate for 38 h at 37±2°C for complete fermentation and used without drying. Supplementation the SSFF with PP resulted in a significant (p<0.01) increase in the males' and females'live body weight. Furthermore, (p<0.01) enhancement in the females' feed conversion ratio of supplemented treatments was observed. It can be concluded that using wet fermented feed with 1 and 2 g of prepared probiotic caused significant improvement in the production performance of Akar Putra chicken especially in the live body weight and growth rate traits.

  During the recent years, solid state fermented feed (SSFF) has been introduced with great success in poultry nutrition. Thus, the present experiment was conducted to evaluate the effect of dry fermented feed with prepared probiotic (PP) on the live body weight, weight gain, feed intake and feed conversion ratio of a local Malaysian chicken (Akar Putra). The experiment comprised of 3 treatments (24 chicken/treatment), with 3 replicates of each (8 chicken/replicate). The treatments consisted of a control group (T1), the mixture of SSFF and PP at the rate 1:1:1 (1 kg of commercial broiler feed+1 liter tap water+1 g PP) in T2 and 1:1:2 (1 kg of commercial broiler feed+1 liter tap water+2 g PP) in T3. The results revealed remarkably significant (p<0.01) improvement in both male and female chicken in terms of final body weight gain, feed intake and feed conversion ratio in treatment groups (T2 and T3) when compared to the control group. The variation ratio of production performance parameters was calculated and best results were indicated in T2 group wherein, 1 g prepared probiotic was used.

  The present study was conducted to investigate the effect of soluble probiotic on the production parameters of local Malaysian chicken (Akar Putra). A total of seventy two 1-day-old Akar Putra chicks were randomly assigned to three treatment groups, each having 3 replicates of 8 chicks. The treatments were as follows: (T1) control, (T2) probiotic supplemented at 1 g/liter tap water, (T3) probiotic supplemented at 2 g/liter tap water. The results revealed that supplementation of soluble probiotic at both the rates resulted in an improved performance of male and female Akar putra chicken. Birds who received 2 g of prepared probiotic per liter of water (T3) exhibited highly improved (p<0.05) body weight, weight gain and feed conversion ratio than other groups. It can be concluded that supplementation of prepared soluble probiotic would be economically beneficial in improving the production performance and health status of Akar Putra chicken.

  In most animals, myofibers number gets established before birth and postnatal growth is due to muscle hypertrophy, with very little contribution from muscle hyperplasia. The muscle myofibers exhibit different contractile, metabolic, physiological, chemical and morphological characteristics but the interaction between these factors and their outcome is not fully understood. Since, there is lack of literature regarding the skeletal muscle morphology of Red jungle fowl (RJ) and Malaysian village chicken (VC), therefore, the present study was undertaken with the aim to evaluate the morphology of skeletal muscle of Red jungle fowl (Gallus gallus Spadiceus) and Malaysian Village Chicken (Gallus gallus Domesticus) and commercial broiler chicken. A total of 150 unsexed birds consisting of 50 Red jungle fowl (RJ), 50 Malaysian village chicken (VC) and 50 commercial broiler (CB) were used in this study. Pectoralis major and bicep femoris were analyzed at the age of 1, 10, 20, 56 and 120 days post hatch. The number of muscle fibers in the breast and thigh muscles increased as the age advanced and the slow growing birds (RJ and VC) had higher Type I muscle fibers in breast and thigh muscles than fast growing CB. The percentage of Type 1 muscle fibers increased as the age advanced due to prolonged activity and also the type of muscle fibers changed throughout the age and activity. The importance of muscle fiber type changes is applicable to determine the future production of birds especially with regard to better quality meat of VC and RJ.

  The digestive organs of Malaysian Village Fowl (MVF) and Broiler Breed (BB) differ in body weight were studied grossly and histologically. Weight of digestive organs and length of small intestine were obtained from fifty male from each breed euthanased from first day after hatch to 4 months. At day 20 body weight of BB was five times greater than those of MVF. The differences between breeds for the weight of vitelline residue, proventriculus, gizzard, liver, pancreas, weight and length of small intestine segments for the absolute and relative to body weight at day one were also obtained. The liver, pancreas and intestinal segments of the two breeds showed increased in relative weight at the 10 days post-hatch and after that the relationship were reversed. At days 20-4 months post-hatch, all organs relative weight of MVF increased except jejunum in 56-120 days and ileum in 56 days. The same patterns observed for intestinal length in both breeds. Day one post-hatch relative lengths of all intestinal segments in MVF were higher than BB. The latter was dominantly showed larger proventricular glands, gizzard glands and gizzard lining membrane. In BB, the villi heights of intestinal mucosa were higher than that of MVF, except in ileum at days 20 and 56 post-hatch. The villus surface areas were constantly greater in BB, the crypt depths were greater in BB, except in 56 and 120 days. There were no different in thickness of muscularis externa in each intestinal segment at the day one and after the 20 days old.

  Thirty males of Red Jungle Fowl (RJF) were divided into 3 equal groups, euthanized at day 1, 10 and 20 days after hatching. The morphometric analyses were performed at three different magnification levels. Different segments (duodenum, jejunum and ileum) and cecum were weighted and length of each small intestinal segments and cecum were determined at a macroscopic level. The mucosa of the intestinal segments was compared and contrasted using both, light and scanning electron microscopy. The villi height, villi surface area, crypt depth and muscularis externa were measured. The body weight was doubled at 10th day and again doubled at 20th day. The weight and length of intestinal segments were significantly higher throughout the experiment except the constant rate of the duodenal and jejunal lengths after 10th days. Relative to body weight, the organs weight and length were declined after 10th days. The duodenal villi height and surface area were greater than the jejunum followed by the ileum. The muscularis externa and crypt depth increased significantly at 10th day. However, the latter showed retardation thereafter. Day one intestinal villi appeared finger-like shape with zigzag arrangement, tongue-like and leaf-like shaped in 10 and 20th days, respectively. The villi distribution and patterns in the middle region of cecum were characteristic. The epithelial cells of the duodenal villi showed more activities and development than those on the jejunum and the ileum throughout the age. The body growth in RJF progresses very slowly while the relative intestinal segment weight and length failed to follow the body weight after 10th days. The duodenal mucosa shows better developmental features than the jejunum and the ileum.
