Abstract

The aim of this study was to reveal the effect of whey powder (WP) supplementation on chemical composition, silage fermentation, in vivo digestibility and net energy lactation (NEL) value of high dry matter (DM) alfalfa silage (Haylage). Alfalfa treated with different doses WP (0, 2, and 4%) were ensiled in plastic cans for 60 days. Nine Kıvırcık rams were used to estimated digestibilities of haylages in 3x3 Latin Square design with fifteen days experimental period. According to the results, the addition of WP significantly increased the DM of alfalfa haylage compared to the control whereas decreased ether extract, crude protein and crude ash. But, cell wall fraction rates of all groups were similar. Relative feed value and physical characteristics other than color improved in WP supplemented groups, and lactic acid rates increased in these groups. In terms of silo acids, the best values were found in the group with 4% WP. On the other hand, the addition of WP increased the organic matter digestibility of haylages, however the effect on other in vivo digestibility of crude protein, crude fiber, nitrogen free extract and neutral detergent fiber was insignificant. Moreover, total digestible nutrients (TDN) and NEL values of haylages were found to be improved with the addition of WP. As a result, it was concluded that in order to obtain quality haylage in the ensiling of high DM and long chopped alfalfa, WP generally can be used as an alternative source of carbohydrates and a 4% whey powder dose can be recommended in the production of haylage especially in the sense of improving silage fermentation.

Abstract

ABSTRACT The study aimed to evaluate the potential use of dried or ensiled paulownia (Paulownia spp.) leaves as roughage source for ruminants. Paulownia tree leaves were collected from one-year-old hybrid (C-125, CAR, and TF-33 clones) trees. Dried paulownia leaves of the clones were different in dry matter (DM), crude ash (CA), crude protein (CP), ether extract (EE), crude fiber (CF), and nitrogen-free extract (NfE) and similar in neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL); however, these values (except EE and ADL) of ensiled leaves were significantly different among the clones. Mean CP, CA, and condensed tannin contents in dried leaves were 15.36, 9.21, and 1.75%, respectively; NDF, ADF, and ADL contents were 38.35, 35.49, and 12.08%, respectively. Mean total volatile fatty acids, in vitro organic matter digestibility (IVOMD), and metabolizable energy (ME) value in dried leaves were 95.26 mmol/L, 76.34%, and 10.77 MJ/kg, respectively, whereas, CO2 and CH4 production were 54.66 and 29.78 mmol/L, respectively. Buffering capacity and water-soluble carbohydrates varied among the pre-ensiled paulownia leaves, although their means were 395.66 mEq/kg DM and 86.63 g/kg DM, respectively. In ensiled leaves, the pH, lactic acid ratio, and acetic acid ratio were 4.98, 11.23, and 2.56%, respectively, and butyric acid was not detected in any of the silages. Mean values of IVOMD and ME in ensiled leaves were 72.30% and 9.93 MJ/kg, respectively. Dried paulownia leaves are a high-quality alternative forage and the ensiled form is of medium quality. Therefore, paulownia leaves could be used as an alternative roughage source for ruminants.

Abstract

Objective: This study aimed to determine the effect of clove oil on in vitro dry matter digestibility (DMD) and metabolizable energy (ME) values of wheat straw. ,Material and Methods: In the research, clove oil (66.6% eugenol) was treated with wheat straw at different doses (0, 50, 100, 200 ppm) and hours (1, 3, 5, 7, 9, 12). Firstly, in vitro cellulase method was applied in the study. In the application of the method, pepsin (2000 FIP-U/g) and also the cellulase enzyme obtained from Trichoderma viride (Onozuka R-10, 1 U/mg activity) were used. Then from obtained values, the DMD value of the feed and the amount of organic matter soluble in the enzyme (ELOS) were found and the in vitro ME values were calculated. Results: Clove etheric oil depending on the increasing dose was increased DMD, ELOS and ME values of wheat straw (P, Amaç:Bu çalışmada, karanfil eterik yağının buğday samanının in vitro KMS ve ME değerlerine etkisinin belirlenmesi amaçlanmıştır.Materyalve Metot: Araştırmada, karanfil yağı (%66.6 eugenol), farklıdoz (0, 50, 100, 200 ppm) ve saatlerde (1,3,5,7,9,12) buğday samanı ile muameleedilmiştir. Çalışmada, öncelikle in vitro Selülaz yöntemi uygulanmıştır. Yöntemin uygulanmasında Trichodermaviride’ den (Onozuka R-10, 1 U/mg aktivite) elde edilen Selülaz enzimi ilePepsin (2000 FIP-U/g) kullanılmıştır. Daha sonra elde edilen değerlerden, yeminKMS değeri ile enzimde çözünebilen organik madde (ELOS) miktarı bulunmuş ve invitro ME değerleri hesaplanmıştır. Bulgular:Karanfileterik yağı artan doza bağlı olarak, buğday samanının KMS, ELOS ve ME değerleriniartırmıştır (P

Abstract

Amaç: Bu çalışmanın amacı, bazı fiğ kuru otları ile botanik fraksiyonlarının yem değerlerinin in situ naylon torba tekniği ile belirlenmesidir. Materyal ve Metot: Araştırmada, %25 çiçeklenmede hasat edilen 2 adi fiğ (Vicia sativa), 2 tüylü fiğ (V. villosa) ve 1 macar fiği (V. pannonica) olmak üzere toplam 5 çeşit fiğ kuru otu ile bunların yaprak ve sapları kullanılmıştır. Öncelikle yemlerin naylon torba tekniği yardımıyla ruminal KM parçalanabilirlikleri elde edilmiştir. Daha sonra KM parçalanabilirlikleri ile Neway programından yararlanılarak ruminal parçalanma karakteristikleri hesaplanmıştır. Ayrıca yemlerin dekara KM ve HP verimlerinden yararlanılarak, in situ parçalanabilirlik verimleri de saptanmıştır. Bulgular: Fiğ çeşitlerinin, sap fraksiyonu hariç, KM ve HP içerikleri benzerdi (P>0.05). Sap fraksiyonu için en yüksek HP değeri (%11.38) EB-82 çeşidinde saptandı (P

Abstract

Dünyada veülkemizde hayvansal kökenli yem hammaddelerinin kullanımının yasaklanmasınabağlı olarak, karma yem sektöründe bitkisel kökenli proteince zengin kaynaklaraağırlık verildiği görülmektedir. Ne var ki, bu kaynakların kısıtlı oluşu, yemfiyatlarında artışa neden olurken, diğer yandan da mevcut stokların hızlatükenmesine ve hammadde yetersizliğine yol açmıştır. Bundan dolayı, hem balıkunu gibi kullanımı kısıtlanan veya yasaklanan hammaddelerin yerini alabilecekhem de soya fasulyesi, ayçiçeği küspesi gibi bitkisel orijinli kaynaklaraalternatif olabilecek, protein içeriği ve besleyici değeri yüksek, aynı zamandagüvenilir yeni kaynak arayışı hız kazanmıştır. Alternatif proteince zenginkaynakların bulunmasıyla hayvan beslemede protein açığının giderilmesi,sürdürülebilir kaliteli yem hammadde tedariki ve çiftliklerde maliyetindüşürülmesi hedeflenmektedir. Bu derlemenin amacı, yem hammaddesi potansiyelibulunan tek hücre proteinleri, yenilebilir böcek türleri, şeker pancarı, manyokürünleri ve bazı ağaç yapraklarının yem değerleri ile bunlara yönelikçalışmalar hakkında bilgi vermektir., Depending onthe prohibition to use animal-origin feed raw materials in the world and ourcountry, it has been seen that herbal origin and protein-rich resources aremainly used in the mixed feed industry. However, since these resources arelimited, it causes an increase in the price of the feed and also paves the wayfor rapid depletion of existing stocks and raw material insufficiency. Therefore, the search for a new reliablesource, which has a high protein content and sustenance that can be an alternativeto the herbal-origin resources such as soya bean and sunflower meal andreplaces the prohibited or restricted raw materials such as fish meal hasgathered speed. It is aimed to meet the protein shortage in animal feeding,sustainable qualified feedstuff raw material supply and decreasing the costs inthe farms by the discovery of alternative protein-rich resources. The purpose of this review is to giveinformation about the research on the single-cell protein feedstuff, edibleinsect species, sugar beet, cassava products and feedstuff values of some treeleaves, which have a feedstuff raw material potential
