This study was carried out in national Stud in Tiaret West of Algeria to understand and to evaluate the normal sexual behavior and libido of stallions (Arabian vs. Barb) while mounting a mare in estrus.Eighty-four stallions were divided to two groups from 5-24 years age (n = 47 Arabian; n = 37 Barb).Results revealed significant differences (p<0.05,p<0.01, p<0.001) in sniffing, libido score, flehmen response; time to first mount with erection, number of mounts to ejaculation and mount time for ejaculatory reaching a mean value of (19.15±10.76;12.23±2.68;p<0.01) second respectively for Arabian an Barb stallion.These stallions were tested in exactly the same place and conditions allows us to discard any side effects due to animal management or any other confounding bias.Our study provided us the knowledge of sexual behavior under Algerian conditions and the distinction between Arabian and Barb stallion.
: Sub-sector of livestock has an important role in the life and development of human resources in Indonesia. An important issue on agribusiness beef cattle is a continuous population decline every year. The application of technology has to be initiated in order to obtain production efficiency and production cost efficiency. One of the factors that affect the productivity of livestock is feed. The major constraints of ruminant feed are low quality of forage, the low level of palatability and digestibility. To solve this problem is making forage waste into wafer feed supplement. The aim of this experiment was to determine the nutrient content on wafer feed supplement and productivity of local calf that were given by wafer feed supplement. This research was conducted at Laboratory of Feed Industry, Bogor Agricultural University and the performance test at Karya Anugrah Rumpin Corporation on March-April 2016. To determine the nutrient content of wafer feed supplements used proximate analysis. The experiment of productivity used 12 heads of male local calves (Sumba Ongol calves) with average body weight around 136±22.46 kg with ages around 12-18 months. The experimental local calves were maintained individually. The experimental design used randomized block design with four treatments and three replications. The treatments were feeding patterns of wafer feed supplement i.e., T1 = 0% by feeding wafer supplement+concentrate+king grass, T2 = 10% by feeding wafer supplement+concentrate+king grass, T3 = King grass+10% by feeding wafer supplement+concentrate, T4 = Concentrate+king grass+10% by feeding wafer supplement. The parameters measured were productivity of local calves, i.e., daily weight gain, final body weight, consumption, dry matter and organic matter digestibility, blood cholestrol, blood glucose, blood protein. It was concluded that feeding pattern wafer feed supplement can increase consumption and not influence condition of local calves. It was concluded that daily weight gain by feeding wafer supplement feed 42-45% higer than conventional feed. High crude protein of wafer feed supplement is good supplement for ruminant in the tropic.
The aim of this study was economic evaluation and investigation of some factors such as season and demographic characters (manager characters) on some productive and reproductive efficiency in sheep production farms under Egyptian conditions. Data were randomly collected from commercial sheep farms from different localities in Menofia governorate located in the south of Nile delta in Egypt. The data included seasons grouped into (cold season) extended from 21 September to 20 March and (warm season) from 21 March to 20 September to determine its effect on birth weight, litter size and kidding interval. The data were collected, summarized and analyzed by statistical computer program (SPSS/PC, 16). The results of the study revealed that warm season had higher parameters for birth weight, litter size and kidding interval than cold season as recorded 2.91 kg, 1.61 and 9.13 months. The manager characters has a significant effect on production of sheep farms as about 31% in production changes were attributed to the changes in demographic characters such as educational level and age of producer.
