ABSTRAKPeningkatan produktivitas ternak dapat dicapai melalui perbaikan aspek teknis pemeliharaan yang meliputi perbaikan genetik, pakan, pengelolaan, perkandangan dan kesehatan ternak. Penelitian ini bertujuan untuk mengevaluasi penerapan aspek teknis pemeliharaan sapi perah berdasarkan Good Dairy Farming Practices (GDFP) pada peternakan sapi perah rakyat di Cibungbulang. Metode penelitian yang digunakan adalah survei dan pembagian kuisioner, observasi serta pengukuran langsung. Data dianalisis secara deskriptif dan disajikan dalam bentuk frekuensi tabulasi untuk menggambarkan karakteristik penerapan setiap aspek pemeliharaan sapi perah. Hasil penelitian menunjukkan bahwa pelaksanaan aspek teknis pemeliharaan sapi perah berdasarkan Good Dairy Farming Practices (GDFP) di peternakan rakyat Cibungbulang sebesar 69,75% pada musim hujan dan 67,25% pada musim kemarau. Aspek kesehatan ternak memperlihatkan nilai yang sangat rendah baik pada musim hujan maupun musim kemarau sehingga perlu mendapatkan perhatian khusus agar produktivitas ternak dapat ditingkatkan secara optimal.Kata kunci: biji kecipir, Trichoderma viride, pH, suhu, protein, serat kasarABSTRACTIncreased dairy cow productivity can be achieved through improving the technical aspects of maintenance which include genetic improvement, feed, management, housing and dairy cow health. This study was done to evaluate the application of the technical aspects of dairy cow maintenance based on the Good Dairy Farming Practices (GDFP) on smallholder dairy farm in Cibungbulang. The research method used was a survey and distribution of questionnaires, observations and direct measurements. Data were analyzed descriptively and presented in frequency tabulations to describe the characteristics and application each aspect of dairy cow maintenance. The results showed that the implementation of technical aspects of dairy cow maintenance was based on the Good Dairy Farming Practices (GDFP) at smallholder dairy farm in Cibungbulang i.e 69.75% in rainy season and 67.25% in dry season. The health aspect of dairy cow shows a very low value both in rainy and dry season so need special attention to increased productivity optimally.Keywords: dairy cow, technical aspects of maintenance, GDFP

В статье представлены материалы о влиянии микотоксинов на здоровье и продуктивность молочного скота. В настоящее время наибольшую опасность для здоровья животных представляют яды микроскопических грибов — микотоксины, что требует разработки методов их устранения по всей цепочке — от поля до потребителя. Известно, что споры грибов, продуцирующих токсины, живут в почве и оттуда передаются растениям, а затем зёрнам. Микотоксины — это вторичные метаболиты грибов, такие как афлатоксины (AF), продуцируемые видами Aspergillus, фумонизины (FUM), зеараленон (ZEN), токсин T-2 (T-2) дезоксиниваленол (DON), продуцируемый видами Fusarium, охратоксин A (OTA), продуцируемый видами Penicillium, и многие другие. Потребление кормов, загрязнённых этими токсинами, вызывает у животных микотоксикозы, которые характеризуются рядом клинических признаков в зависимости от вида токсинов. У животных снижается продуктивность и поедаемость кормов, увеличивается восприимчивость к различным заболеваниям. Существует две формы микотоксикозов: острые микотоксикозы, возникающие из-за потребления высокой разовой дозы микотоксинов, и хронические микотоксикозы из-за постоянного потребления низких уровней микотоксинов в течение продолжительного времени. Хронический токсикоз, вызванный низким уровнем воздействия микотоксинов в течение продолжительного времени, представляет собой более распространённую проблему для здоровья животных и качества пищевых продуктов для людей. В целом объёмистые корма и зерновые компоненты, входящие в состав рациона, подвержены загрязнению афлатоксинами на всех этапах производства кормов, таких как сбор, транспортировка, хранение, переработка и упаковка. В последнее время учёные стали уделять больше внимания загрязнению кормов микотоксинами и механизмам борьбы с разными группами токсинов. Основной задачей при производстве кормов является снижение концентрации токсинов на всех этапах — от поля до рациона животных. This article focuses on the effect of mycotoxins on dairy cow health and productivity. To this day toxins produced by various fungi are one of the most serious dangers for cattle. It is known that spores usually contaminate plant and later grain material from soil. Mycotoxins are secondary metabolites such as aflatoxins (AF) produced by Aspergillus spp., fumonisins (FUM), zearalenone (ZEN), T-2 (T-2), deoxynivalenol (DON) produced by Fusarium spp., ochratoxin A (OTA) produced by Penicillium spp., and many others. Toxin-contaminated forage causes mycotoxicoses of different severity depending on toxin type. Livestock shows low productivity and appetite but high susceptibility to diseases There are two types of mycotoxicoses: acute mycotoxicoses, caused by high concentration of toxins and the chronic ones, occurring due to constant long consumption of low toxin levels. Chronic toxicosis is a more common problem for animal health and food quality. Bulk and grain feed are highly affected by aflatoxins at such production stages as harvesting, transporting, storage, processing and packaging. Lately scientists drew more attention to toxin contamination issue and methods controlling their accumulation. The main task when producing forage is to reduce toxin concentration at all the production stages.

The purpose of this review is to identify the main influencing factors related to dairy cow health as it impacts the intensity of greenhouse gas emissions considering known data presented in the literature. For this study, we define the emission intensity as CO2 equivalents per kilogram of milk. In dairy cows, a high dry matter (DM) intake (25 kg/d) leads to an higher absolute methane emission compared to a lower DM intake (10 kg/d). However, the emission intensity is decreased at a high performance level. The emissions caused by DM intake to cover the energy requirement for maintenance are distributed over a higher milk yield. Therefore, the emission intensity per kilogram of product is decreased for high-yielding animals with a high DM intake. Apart from that, animal diseases as well as poor environmental or nutritional conditions are responsible for a decreased DM intake and a compromised performance. As a result, animal diseases not only mean reduced productivity, but also increased emission intensity. The productive life-span of a dairy cow is closely related to animal health, and the impact on emission intensity is enormous. A model calculation shows that cows with five to eight lactations could have a reduced emission intensity of up to 40% compared to animals that have left the herd after their first lactation. This supports the general efforts to increase longevity of dairy cows by an improved health management including all measures to prevent diseases.

Dry period management of the dairy cow focuses on maximising milk production during the subsequent lactation but may include procedures that negatively affect dry cow health and welfare. A survey of dairy farmers in the UK was conducted to investigate dry cow management procedures. The questionnaire was completed by 148 farmers. Most farms (84 per cent) kept dry cows in dynamic social groups. The median length of the dry period was 56 days, and 83 per cent of farms stopped milking abruptly, regardless of milk production level at dry-off. Twenty-seven per cent of cows from respondent farms produced more than 20 kg of milk per day at dry-off. The majority of farms (78 per cent) used antibiotic dry cow intramammary tubes at dry-off, in combination with internal or external teat sealants. Procedures that were commonly practised and potentially stressful for dry cows included abrupt cessation of milking of high yielding cows and frequent changes in diet and social environment.
