“…These results suggest that even if supplied ad libitum, as was done in this study, solid feed still represents a small margin of TC at this stage of life. This is a relevant finding, considering that the solid diet is beneficial to ruminal development, as demonstrated by Górka et al (2011).…”

The aim of this study was to analyze the economic viability of producing dairy goat kids fed liquid diets in alternative of goat milk and slaughtered at two different ages. Forty-eight male newborn Saanen and Alpine kids were selected and allocated to four groups using a completely randomized factorial design: goat milk (GM), cow milk (CM), commercial milk replacer (CMR) and fermented cow colostrum (FC). Each group was then divided into two groups: slaughter at 60 and 90 days of age. The animals received Tifton hay and concentrate ad libitum. The values of total costs of liquid and solid feed plus labor, income and average gross margin were calculated. The data were then analyzed using the Monte Carlo techniques with the @Risk 5.5 software, with 1000 iterations of the variables being studied through the model. The kids fed GM and CMR generated negative profitability values when slaughtered at 60 days (US$ −16.4 and US$ −2.17, respectively) and also at 90 days (US$ −30.8 and US$ −0.18, respectively). The risk analysis showed that there is a 98% probability that profitability would be negative when GM is used. In this regard, CM and FC presented low risk when the kids were slaughtered at 60 days (8.5% and 21.2%, respectively) and an even lower risk when animals were slaughtered at 90 days (5.2% and 3.8%, respectively). The kids fed CM and slaughtered at 90 days presented the highest average gross income (US$ 67.88) and also average gross margin (US$ 18.43/animal). For the 60-day rearing regime to be economically viable, the CMR cost should not exceed 11.47% of the animal-selling price. This implies that the replacer cannot cost more than US$ 0.39 and 0.43/kg for the 60-and 90-day feeding regimes, respectively. The sensitivity analysis showed that the variables with the greatest impact on the final model's results were animal selling price, liquid diet cost, final weight at slaughter and labor. In conclusion, the production of male dairy goat kids can be economically viable when the kids diet consists mainly of either cow milk or fermented colostrum, especially when kids are slaughtered at 90 days of age.

“…Researchers confirmed that additives containing butyrate and propionate may affect weaning date (Ferreira & Bittar, 2011). It is generally accepted that the presence of VFAs is one of the effective prerequisites for rumen development (Martin et al, 1959;Gorka et al, 2011). It was demonstrated that butyric acid stimulates epithelial cell proliferation.…”

“…Hayat et al (2010) concluded that using carboxylic acid salts such as malate in lamb diets increased body weight, concentration of serum glucose and β-hydroxybutyrate concentrations. Recently, Gorka et al (2011) reported that using sodium butyrate in calf liquid feed indirectly affected the development of the small intestine and rumen of the calf. Therefore, the objective of this study was to evaluate the supplementation of encapsulated (rumen protected) calcium butyrate in milk replacer on some rumen and blood parameters and performance of early weaned female Holstein calves.…”

The aim of this study was to determine the effects of coated calcium butyrate (CCB) on calf performance and some blood parameters. Sixteen female Holstein calves with a mean age of 3 ± 1 d were divided into two equal groups and fed a milk replacer supplemented with 3 g of coated calcium butyrate (CCB)/day or with no coated calcium butyrate (NCB). The calves had free access to solid feed and water. Body weight was measured at days 3, 12, 24, 36 and 48 (weaning day). Respiratory rate and rectal temperature (within first 4 weeks of life), feed intake and faecal score (during the whole experimental period) were recorded daily. Rumen fluid was taken for volatile fatty acid (VFA) determination on days 33 and 48, and structural growth (rump height, withers height and hip width) was recorded on days 3, 24 and 48. Blood samples were collected on days 1, 12, 24, 36 and 48. Feed intake, average daily gain, feed conversion ratio and structural growth of calves were improved by CCB supplementation. There were no significant differences on rectal temperature, respiratory rate and faecal score between the treatments. Rumen concentration of total VFAs increased and the VFA profile was affected on days 33 and 48 by CCB supplementation. The supplementation of milk replacer of calves with coated calcium butyrate significantly increased serum concentrations of glucose, insulin and β-hydroxybutyrate. Serum concentration of cortisol in the CCB calves was numerically lower than in NCB. In conclusion, supplementation of calves' milk replacer with the coated calcium butyrate could improve calf performance. ________________________________________________________________________________

Öz: Süt sığırcılığında sürü yönetimi ve devamlılığının en önemli ve vazgeçilmez öğelerinden biri de buzağıların bakımı ve beslenmesidir. Sütten kesim öncesindeki buzağılar, çevresel değişimler, beslenme problemleri, zayıf immunite ve patojenler gibi birçok stres faktörü ile karşı karşıya kalmaktadırlar. Süt sığırcılığındaki finansal kayıpların önemli bir bölümünü buzağılarda meydana gelen hastalıklar ve buzağı ölümleri oluşturmaktadır. Söz konusu finansal kayıplar direkt buzağı ölümü, uzun süreli tedavi masrafları ve performans düşüklüğü şeklinde ortaya çıkmaktadır. Sütten kesime kadar olan dönemde, üzerinde durulması gereken en önemli konulardan biri de rumenin erken ve sağlıklı bir şekilde geliştirilmesi ile optimum zamanda katı yemlere geçişin sağlanabilmesidir. Buzağıların doğumdan sütten kesime kadar olan dönemde nasıl beslenmeleri gerektiği ile ilgili stratejiler her geçen gün değişmektedir. Buzağıların bir günde ne kadar miktarda süt, buzağı başlangıç yemi ve kaba yem tüketmeleri gerektiği ve bu yemlerin hangi zaman aralıklarında ve ne kadar süre ile verilmesi gerektiğine ilişkin birçok bilimsel araştırma yapılmıştır. Besleme yöntemindeki bilimsel gelişmeler ve iyileştirmeler, buzağının sağlıklı bir şekilde rumen gelişimine katkıda bulunarak hastalıklara karşı olan duyarlılığını azaltmasının yanında, canlı ağırlık artışını olumlu yönde etkileyebileceğine ve buzağı mortalitesini azaltabileceğine dair yeni prensipler bulunmaktadır.Anahtar Kelimeler: Besleme, Buzağı, Prensipler, Sütten kesim öncesi. Feeding Principles in Preweaning CalvesAbstract: In dairy farming, one of the most important and indispensable element of dairy herd management and continuity is care and nourishment of the calves. Calves before weaning are faced with many stress factors such as environmental changes, nutritional problems, poor immunity and pathogens. The disease and deaths occurring in the calves constitute the majority of the financial losses in dairy farming. Aforementioned financial losses show up in the form of direct calf death, costs of long term treatment and decrease in performance. One of the most important issues that should be emphasized till calves wean is the development of rumen in an early and healthy way and enabling transition to solid fodder at optimum time. The strategies regarding how to feed the calves from birth to weaning changes from day to day. Many studies have been conducted related to how much milk, calf starter and coarse fodder should calves consume per day and at which intervals and for how long should these fodders be administered. There are new principles about the scientific progress and improvements in the feeding method which may reduce susceptibility to diseases beside affecting live weight gain positively and reducing calf mortality by contributing to rumen development of calves.
