“…Nevertheless, in this research, the rate of yield increased from 0.18 to 0.24, which agrees with Zambom et al (2005), who found values ranging from 0.10 to 0.27, and Tufarelli et al (2009), whose values ranged from 0.21 to 0.29 for the increased rate of yield until lactation peak. The largest values in this research may be related to animal genetics, intake of dry matter, or diet compositions.…”

-This study aimed to evaluate the effects of soybean hulls (SBH) as a ground corn replacement (0, 50, and 100% SBH) on the parameters of the lactation curve and on lactation curves and milk composition. Fourteen multiparous Saanen goats were used during their lactation period, from kidding until the drying of their milk on the 228th day of lactation, and were distributed in a completely randomised design. The data was analysed using Bayesian methodology to minimise the effect of the low number of animals and to allow for comparison of the curve parameters estimated by Wood's nonlinear model. The SBH had no effect on the initial milk yield; nevertheless, the SBH reduced the rate of yield until lactation peak and accelerated the declining rate of yield after lactation. The treatments did not affect dry matter intake. The inclusion of SBH increased the fat content in the milk, which was also influenced by the lactation stage of the goats. Effects were observed on polyunsaturated fatty acids (PUFA), PUFA/total AG ratio, and the n-6:n-3 ratio of goat milk fat. The lactation stage changed the content of saturated fatty acid, monounsaturated fatty acid, and C18:2 (conjugated linoleic acid). The SBH can therefore be used as a ground corn replacement in the diets of lactating goats, as changes in the lactation curve parameters did not result in changes in total yields. Nevertheless, if the milk fat increases, then as quality rises, so could payment by quality, and thus an increase in profit margins per liter of milk sold.

“…But forage to concentrate ratio in this trial might not affect milk yield and milk composition since their rations were not significantly different as shown in Table 2. As reported by Tufarelli et al (2009), ratio 35/65 forage to concentrate provided greater milk yield compared to 50/50 ratio and 65/35 ratios without influencing milk composition during lactation period of Jonica breed goats.…”

“…The different levels of protein and energy response on milk yields and milk composition yields between different research reports might be due to many factors such as forage to concentrate ratio (Tufarelli et al 2009;Park et al 2010), breed and traits (Ciappesoni et al 2004). But forage to concentrate ratio in this trial might not affect milk yield and milk composition since their rations were not significantly different as shown in Table 2.…”

ABSTRAKSupriyati, Krisnan R, Budiarsana IGM, Praharani L. 2016. Pengaruh dari perbedaan tingkatan protein dan energi pakan konsentrat terhadap asupan nutrisi dan produksi susu pada kambing Saanen x Etawah silangan. JITV 21(2): 88-95. DOI: http://dx.doi.org/10. 14334/jitv.v21i2.1356 Kambing perah turut berkontribusi pada ketahanan pangan dan nutrisi. Akan tetapi, informasi terkait konsumsi nutrisi dan produksi susu (termasuk komposisinya) kambing persilangan Saanen x Etawah (SAPERA) masih terbatas. Penelitian ini bertujuan untuk mengevaluasi asupan nutrisi, produksi susu dan komposisi kandungan nutrisi kambing SAPERA yang sedang menyusui yang diberi pakan dengan tingkat energi dan protein konsentrat yang berbeda. Tiga puluh kambing SAPERA multipara dianalisis menggunakan rancangan acak kelompok dengan tiga perlakuan (R1, R2, dan R3) dan 10 pengulangan selama 12 minggu laktasi. Pakan konsentrat yang diformulasikan mengandung 18% PK dan 72% TDN (R1), 17% PK dan 75% TDN (R2), dan 16% PK dan 78% TDN (R3). Domba betina dipelihara dalam kandang individu dan diberikan pakan basal (cacahan rumput raja segar secara ad libitum sebanyak 500 g dari campuran pakan hijauan) dan 1 kg konsentrat perlakuan. Hasil penelitian menunjukkan bahwa perlakuan (R1, R2, dan R3) memiliki pengaruh nyata (P<0.05) terhadap asupan PK, PT, Ca, P dan FCR tetapi tidak berpengaruh nyata (P>0.05) terhadap asupan BK dan TDN. Perbedaan yang tidak nyata ditemukan pada produksi dan komposisi susu antar perlakuan. Berdasarkan hasil penelitian, dapat disimpulkan bahwa pakan terbaik untuk kambing SAPERA menyusui adalah campuran dari rumput cacah, campuram hijauan dan konsentrat (16% PK dan 78% TDN) dengan 160g/kg PK dan 750 g/kg TDN dari total BK yang memproduksi susu sebanyak 1.55 kg/hari dengan kandungan 90 g/hari lemak, 43 g/hari protein dan 75 g/hari laktosa. Dairy goat contributes to food and nutrition security. However, information on nutrient consumption and milk yield, as well as milk composition of Saanen x Etawah (SAPERA) grade goat is limited. This experiment was done to evaluated nutrient intake, milk yield and its composition of lactating SAPERA goats fed with different levels of dietary energy and protein in concentrate diet. Thirty multiparous SAPERA goats were used in a randomized block design with three treatments (R1, R2 and R3) and ten replications for 12 weeks of lactation. The concentrate diets were formulated to contain: 18% CP and 72% TDN (R1), 17% CP and 75% TDN (R2), 16% CP and 78% TDN (R3). Those does were penned individually, and fed by basal diet (fresh chopped King Grass ad libitum, 500 g of fresh mixed forages) and 1 kg of experimental concentrate. Results showed that the treatments had significant (P<0.05) effects on CP, DIP, Ca, P intakes and FCR but had no significant (P>0.05) effects on DM and TDN intake. No significant differences were found in milk yield and milk composition between treatments. In conclusion, this trial suggested that the best feed for lactating SAPERA goats was the mixture of chopped grasses, mixed f...

The in vitro effects of goat's milk from different sources (Jonica, Saanen, and Priska breeds plus a commercial preparation) on healthy human peripheral blood mononuclear cells (PBMCs) were evaluated in terms of nitric oxide (NO) and cytokine release. According to the incubation time (24 h or 48 h) used all milks could induce release of NO from monocytes. In this context, however, in the presence of a commercial milk preparation inhibition of lypopolysaccharide (LPS)-induce NO generation was evident. Also polymorphonuclear cells stimulated with the various milks released detectable amounts of NO. In the case of Priska milk inhibition of LPS-mediated NO generation was observed. Despite a broad array of cytokines tested [Interleukin (IL)-4, IL-5, IL-6, IL-10, IL-12, IL-13, IL-17, Tumor Necrosis Factor (TNF)-alpha, Transforming Growth Factor-beta and Granulocyte Colony Stimulating Factor] only IL-10, TNF-alpha, and IL-6 were released by PBMCs upon stimulation with various milks. Taken together, these data indicate that goat's milk for its capacity to produce NO may exert a cardioprotective and anti-atherogenic effect in consumers. Moreover, induction of proinflammatory (TNF-alpha and IL-6) and anti-inflammatory (IL-10) cytokines suggests the ability of this milk to maintain immune homeostasis in the immunocompromised host (e.g., aged people).
