The objective of this study was to investigate the incidence of repeat breeding in dairy cows under tropical condition. This was a preliminary study conducted in Sinjai Regency, Indonesia. A total of 82 Holstein Friesian lactating cows from five dairy farmer groups were used in the present study. Of the 82 cows, 75.6% eventually became pregnant after repeated inseminations (AI). The incidence of repeat breeding in this area was very high (62%). Days in milk (DIM) at first AI, first AI conception rate, and calving to conception interval were 62.5±19.3 days, 0%, and 202.8±150.0 days, respectively. There was no difference in DIM at first AI between repeat breeders and normal fertility cows (60.4±15.2 days vs 68.3±28.6 days). However, normal fertility cows required only 123.3±52.9 days to conceive and 2.4±0.8 inseminations per pregnancy, whereas repeat breeders required significantly more days to conceive (222.9±134.1 days) and more inseminations per pregnancy (4.8±0.9). In conclusion, repeat breeder dairy cows under tropical condition had very poor and reduced reproductive performance.

The present study was conducted to determine the effect of feeding time restriction on thyroid hormone and blood metabolites concentration of broiler chickens during feed restriction and realimentation period. Four hundred of 7 days-old unsexed broiler chicken of Lohmann commercial strain were arranged in a completely randomized design with 5 treatments and analyzed based on ANOVA. The treatments were: chicks fed ad libitum as a control treatment (R-0); chicks had free access to feed during two periods of 2 h (08:00-10:00 and 16:00-18:00) from 7-14 d of age (R-1) and 7-21 d of age (R-2); chicks had free access to feed during two periods of 4 h (08:00-12:00 and 16:00-20:00) from 7-14 d of age (R-3) and 7-21 d of age (R-4). The treatments consisted of 4 replicates with 20 chicks each. During feeding time restriction from 7 to 21 d of age, thyroid hormone and albumin plasma concentration of R-2 and R-4 were lower (P3 and T4) and blood metabolite (albumin) decreased during feeding time restriction for 4 and 8 h per d from 7 to 21 d of age and it returns to normal during realimentation period.

The characteristics and in vitro fertilization (IVF) ability of ram spermatozoa collected from cauda epididymal was examined. Ejaculated spermatozoa was used as control group in this experiment. Characteristics of spermatozoa including the percentage of progressive motility, viability, abnormality and membrane integrity were evaluated before and after freezing. Fertilization ability of post-thawed spermatozoa in both group was examined based on the pronucleus formation after IVF of in vitro matured (IVM) oocytes. Results from these study showed that there were no significant differences in the characteristics between cauda epididymal and ejaculated spermatozoa before freezing. After freezing, motility of ejaculated spermatozoa was higher than epididymal spermatozoa (54.00±2.24% vs 48.00±4.47%), however the membrane integrity of epididymal spermatozoa was higher than ejaculated spermatozoa (75.38±9.32% vs 65.54±11.88%) (P experiment revealed that the ability of post-thawed epididymal spermatozoa to fertilize oocytes (61.40%, 42.98%, 18.42% for total, normal and polysperm, respectively) did not differ from that of ejaculated spermatozoa (66.67%, 48.78%, 17.89% for total, normal and polysperm, respectively). These results indicate that ram spermatozoa collected from cauda epididymal and then frozen have the ability to fertilize ram ooctyes in vitro in the similar rate with ejaculated spermatozoa.

The growth and distribution patterns of carcass fat were investigated in three breeds of beef cattle entering fattening phase. The study involved 23 grass-fed steer Brahman, 24 Hereford and 22 Brahmanx Hereford crosses with a live weight range from 300-600 kg. An allometric Huxley model was used to study the growth and distribution patterns of fat tissue within wholesale cut. In most cases, Brahmans had significantly higher growth coefficients than Herefords and/or BrahmanxHereford crosses while Herefords and BrahmanxHereford crosses had similar growth coefficients in wholesale cuts. At log natural of 75 kg side muscle+bone weight (4.313 kg), Herefords had significantly a higher fat weight within wholesale cuts than Brahmans and BrahmanxHereford crosses. Comparison at log natural of 114 kg side muscle+bone weight (4.733 kg), whilst Brahmans and Herefords were similar in fat weight distribution, the cross-bred steer had lower fat weights than the other two breed groups in almost all wholesale cuts.

Sheep fattening farms have been recently growing rapidly to produce better quality of sheep meat and fullfill consumer's demand. Sheep fattening and breeding farms should be developed proportionally to obtain sustainable sheep flock in the market. Twelve male lambs (less than one year old) were selected based on their average daily gain (ADG), consisting into two groups: 6 fast growing (FG) and 6 slow growing (SG) sheep. Some morphometric parameters in body and head parts of sheep and their carcass production and composition were measured and compared between the groups. The results show that chest circumference, body height, body length, head length and muzzle, top and bottom neck circumferences of FG sheep were significantly higher than in SG sheep (P0.05). It is concluded that selection of fast growing sheep can be recommended by using some morphometric parameters. The selection would not also negatively affect the weight and percentage of carcass composition.

Two experiments were conducted to investigate the effects of addition of lactic acid bacteria (LAB) inoculant from king grass and a commercial inoculant of L. plantarum on fermentation characteristics and nutrient digestibility of rice crop residue-based silage. In experiment 1, mixture of rice crop residue (RC), soybean curd residue (SC) and cassava waste (CW) in a 80 : 10 : 10 (on dry matter basis) ratio was used as silage material. Four treatments silage were (A) RC + SC + CW as a control; (B) RC + SC + CW + LAB inoculant from king grass (2%, v/w) ; (C) RC + SC + CW + LAB inoculant from king grass (3%, v/w); (D) RC + SC + CW + L. plantarum inoculant (2%, v/w). In experiment 2, six Kacang goats were used in a 6 × 3 Youden square experiment and fed elephant grass, rice straw, and rice crop residue-based silage. The results showed that crude protein (CP) content in silages B, C, and D was slightly higher than silage A. Lactic acid concentration was significantly higher (PL. plantarum inoculant.

Arbuscular Mycorrhizal Fungi (AMF) is a symbiotic association between plant roots and fungi. Their major role is to enhance nutrient and water uptake by the host plants. The objective of this research was to study the role of AMF in enhancing productivity, nutritional quality and tolerance mechanism of Stylosanthes seabrana in drought conditions. This research used a completely randomized design with four treatments: A0 (without AMF), A1 (without AMF in drought), A2 (with AMF), and A3 (with AMF in drought) in S. seabrana. Parameters observed were the soil moisture content, water potential of shoot, relative water content of leaf (RWC), root length, shoot and root dry weight, proline, soluble sugars, crude protein, gas production, and digestibility of organic matter. The data were analyzed with analysis of variance (ANOVA) and the differences between treatments were analyzed with Duncan Multiple Range test. Results showed that inoculation of AMF could enhance leaf water potential, shoot and root dry weight, crude protein, gas production, digestibility of organic matter, but decreased proline and soluble sugars significantly (PS. seabrana seems likely through accumulating organicosmolytes such as prolines and soluble sugars.

Anoa, which is the endemic animal in Indonesia, its population is unevitably decreasing, therefore anoa included in the list of endangered species by International Union for Conservation of Nature (IUCN). The experiment was aimed to apply the artificial insemination (AI) technique for anoa and to examine their parturition behavior. The experiment involved 2 males and 5 females anoa at Taman Safari Indonesia Bogor. Semen was collected by electroejaculator, then evaluated and diluted in Tris-egg yolk extender. The anesthetized estrous females were inseminated intracervically with extended semen (100x106 sperm/1.0 mL). Females which did not show estrous signs during 2-3 cycles after AI were predicted pregnant, and therefore confirmed by ultrasonography. As a comparison, another predicted-pregnant female after natural mating was scanned. The results showed that intracervical AI resulted pregnancy in one female, and the gestation period of anoa was ranged from 313 d (AI) to 324 d (natural mating). There were three stages of parturition process was observed: Stage 1 was characterized by the abdominal contraction and amniotic membrane rupture, Stage 2 was characterized by the fetal expulsions, and Stage 3 was characterized by the placental expulsions and ingestion of placenta by the dam. The duration of each stage of parturition was 6-8 h (stage 1), 30-60 min (stage 2), and 15-180 min (stage 3). It is concluded that AI technique was applicable to anoa in captivity, and the parturation behavior of anoa was comparable to buffalo and cattle. However, the fetal delivery occurred when the dam was in standing position and the dam ingested the placenta.

Study was conducted in the regency of Minahasa to estimate horse live weight using its chest girth, body length and body volume formula (cylinder volume formula) represented by animal chest girth and body length dimensions, particularly focused in Minahasa local horses. Data on animal live weight (LW), body length (BL), chest girth (CG) and body volume were collected from 221 stallions kept by traditional household farmers. Animal body volume was calculated using cylinder volume formula with CG and BL as the components of its formula. Regression analysis was carried out for LW with all the linear body measurements. The data were classified on the basis of age. Age significantly (P < 0.05) influenced the body measurements except animal body length (P>0.05). Animal live weight was predicted by simple regression models using dependent variable (Y) of the animal live weight and independent variable (X) of the animal body measurement, either body length, chest girth, or body volume. The correlations between all pairs of measurements were highly significant (P < 0.01) for all age groups. Regression analysis showed that live weight could be predicted accurately from body volume (R2= 0.92) and chest girth (R2= 0.90). Simple regression model that can be recommended to predict horse live weight based on body volume with their age groups ranging from 3 to ≥10 years old was as follow: Live weight (kg)= 5.044 + 1.87088 body volume (liters). The analyses of data on horse chest girth, body length and body volume formula provided quantitative measure of body size and shape that were desirable, as they enable genetic parameters for these traits to be estimated and also included in breeding programs.
