Sustainability of Forage Systems in Small Holder Dairy Cattle in The Plateau in East Java

Abstract. This study aimed to describe the sustainability of forage system in the small holder dairy cattle  in the plateau in East Java, in particular related to the nutrient content. The method used was survey (interviews, questionnaires, field observations and sampling) at the cooperation unit, farmers, livestock and farming location in one of the areas of dairy cattle cooperation in the plateau (Cooperation of SAE Pujon-Malang). The data obtained were analyzed through descriptive and regression statistics. The results showed that forage system dominantly given during dry and rainy seasons are elephant grass and corn stalks. Linear regression equation for the nutrient content of elephant grass is TDN= 40.516 + 1.404 CP, while corn trees is TDN= 56.212 + 0.740 CP. The conclusion showed that the dependent variable is largely influenced by external factors (environment). Improved continuity of availability of forage can be done by increasing the feeding system in the region (plateau) as well as the support from outside the region. Key words: plateau, dairy cattle, forage  Abstrak.

Model of Small Holders Dairy Cattle Waste Pollution at Several Natural Physical and Economic Social Conditions: A Case Study in the Province of Central Java

Most of dairy farmings in Indonesia are managed in the forms of smallholder farmings that give more attention to productivity rather than ecological concerns. The purpose of this study was to make models of dairy cattle animal waste pollution on clean water quality and degree of smell at several regions with different natural physical and economic social conditions. This study also investigated the waste management that match with the characteristics, behavior, and the attitude of the farmers in each region.  System approach was used as the method of this study through model simulation with program of Powersim 2.5c. Model compiled based on to component situation of livestock, condition of environment and situation of farmer. Determination of regional sample of sub-province or town until chosen countryside conducted with multistage sampling without randomization (purposive sampling).  Based on the result of research can be concluded that (1) low natural physical region and low economic social condition to have endangering pollution level of environment, (2) the waste management for the region with high natural physical and high economic social of bio gas and composting accompanied by removing to excess of animal waste for regional with low natural physical and low economic social.

National Breeding System of Dairy Cattle Husbandry

The husbandry of domestic dairy cattle as one of the components of  livestock sub-sector development is hopefully to increase numerously the capacity and the quality on its milk production, to gradually meet national milk demand and face the competitiveness at the global. The achievement of this purpose should be supported by the production of dairy breeding stock in good quality and sufficient number to increase efficiency of both quantity and quality of domestic milk production. One of important aspect that should be prepared is in determining national breeding system of dairy cattle that can function effectively as guidance and regulation for producing, distributing, and using dairy cattle as “domestic breeding stock”. As in other livestock, breeding system of dairy cattle basically constituted of three main subsystems, i.e. production , distribution and marketing, and quality establishment subsystem. The paper discusses some aspects of these three subsystems to give considerable input in preparing the national concept of dairy cattle breeding system. enterprise (Animal Production 1(2): 43-55 (1999) KeyWords: dairy cattle, breeding stock, milk production.

Profit Analysis of Small Holder Dairy Cattle Farm on Group and Individual System in Banyumas Regency

This research is aimed to study production, technical and the profit of group and individual system on smallholder dairy cattle farm. The research has been conducted in Banyumas Regency. Data collection was done by surveying about 80 farmers, Unit Output Price Cobb-Douglas Profit Function estimation employed Ordinary Leas Square (OLS) method. The different of variable from the result of profit estimation. Profit function analysis on group system showed that manpower pay, animal age, lactation period, lactation month and farmer education have a significant influence on the profit. Whereas, on individual system influence of manpower pay, animal age and lactation month were significant on the profit. Dummy variable showed that group system has more profit than individual system, it was because on group system; (1) has cheaper price on forage and concentrate cost, (2) has higher average of production result, and (3) has higher price of  milk per unit.

Prévalence et facteurs de risque de l'infection par Coxiella Burnettii chez les ruminants d'élevage au Québec

Coxiella burnetii est une bactérie zoonotique affectant un grand nombre d’espèces animales. Chez les ruminants domestiques, l’infection est généralement asymptomatique, mais parfois associée à des problèmes reproducteurs. Néanmoins, le cycle de transmission de l’infection chez ceux-ci demeure peu connu. Dans ce contexte, nous avons réalisé une étude auprès de fermes bovines, ovines et caprines dans deux régions administratives du Québec afin d’estimer les prévalences de cette infection et d’identifier les facteurs de risque, aux niveaux individuel et troupeau, associés à la positivité. Nous avons estimé une prévalence de positivité au niveau troupeau de 44.6 % (IC95%=33.0-56.6) chez les bovins, de 70.8 % (IC95% =48.9-87.4) chez les ovins et de 66.7 % (IC95% =22.3-95.7) chez les caprins. Une association a été observée chez les troupeaux bovins entre leur positivité et la densité de petits ruminants par kilomètre carré dans un rayon de cinq kilomètres entourant la ferme. Chez les petits ruminants, une association avec la positivité des troupeaux a été observée avec la taille des troupeaux et la présence d’un chien sur la ferme. Au niveau individuel, le nombre de jours en lait ainsi que l’âge des petits ruminants étaient associés à la positivité, et ce dernier facteur était modulé par l’accès des animaux au pâturage. Aucun agrégat spatial de fermes positives n’a été détecté chez aucune des trois espèces. L’infection par Coxiella burnetii est donc fréquente dans les troupeaux de ruminants domestiques québécois et semble associée à certaines pratiques de régie et à la présence, ou proximité, d’autres animaux domestiques.

Identification of a bisegmented double-stranded RNA virus (picobirnavirus) in calf faeces

To determine the incidence of rotavirus infection among dairy herds in the State of Sdo Paulo, Brazil, 576 faecal samples obtained from calves aged 1-45 days with and without diarrhoea, reared on 63 dairy cattle farms, were analyzed. Polyacrylamide gel electrophoresis (PAGE) identified 28 samples positive for group A rotavirus, while four samples, two diarrhoeic and two non-diarrhoeic, showed a bisegmented genome with a typical picobirnavirus pattern. Electron microscopy revealed spherical virus particles with a diameter of 37 nm and without a defined surface structure. The present study is the first report of a bisegmented virus identified in cattle in Brazil. (C) 2003 Elsevier B.V. Ltd. All rights reserved.

Seroprevalence estimation and risk factors for A. marginale on smallholder dairy farms in Tanzania

A cross-sectional serological survey of A. marginale was conducted on 200 randomly selected smallholder farms in each of the Tanga and Iringa Regions of Tanzania between January and April 1999. Sera, from dairy cattle of all ages, sexes and breeds were tested for antibodies against A. marginale using an indirect enzyme-linked immunosorbent assay. Antibodies to A. marginale were present in cattle throughout the study areas and the overall prevalence was 20% for Tanga and 37% for Iringa. The forces of infection based on the age seroprevalence profile were estimated at 8 for Tanga and 15 for Iringa per 100 cattle years-risk, respectively. In both regions, seroprevalence increased with age (β = 0.01 and 0.017 per year of age, p < 0.005, in Tanga and Iringa, respectively). Older animals in Iringa were significantly and negatively associated with decreased seropositivity (β = −0.002, p = 0.0029). Further results of logistic regression models reveal that geographic location of animals in Tanga was associated with seropositivity (odds ratio (OR) = 2.94, p = 0.005, for Tanga Rural and OR = 2.38, p = 0.066, for Muheza). Animals acquired as a gift in Iringa had higher odds for seropositivity than brought-in cattle (OR = 2.44, p = 0.005). Our study has identified and quantified some key risk factors that can guide planners devising disease control strategies.
