Total Digestible Nutrient

 ABSTRAKPenelitian ini didisain untuk mengevaluasi kecernaan nutrisi, dinyatakan dalam TDN, dari ransum yang mengandung PUFA konsentrat yang disuplementasi yeast dan Curcuma xanthorrhiza Roxb pada kambing perah.  Dua puluh ekor kambing Peranakan Ettawah (PE) pada fase laktasi akhir dialokasikan kedalam 6 perlakuan dengan Rancangan Acak Kelompok.  Perlakuan tersebut adalah: PD0: PUFA-diet tanpa suplemen, PDA: dengan Asifit, PDY: dengan 0,5% yeast, PDC: dengan 2% curcuma, dan PDM: dengan 0,5% yeast + 2% curcuma.  Ransum- PUFA terdiri atas 80% PUFA- konsentrat sebagai ransum dasar dan 20% rumput gajah.   Sumber PUFA terdiri atas jagung giling sangrai, tepung kedelai sangrai, dan minyak jagung.  Hasil menunjukkan bahwa  konsumsi  DM, OM, CP, CF, NFE, ADF, dan GE tidak terpengaruh oleh perlakuan.  Namun, EE dan NDF  antarperlakuan berbeda  signifikan (P<0.05), sedang Ca dan P  berbeda sangat signifikan (P<0.01).  Kandungan nutrisi yang tinggi (DM, OM, CP, EE, CF, NDF, and GE)  ditemukan di feces pada kambing dengan perlakuan Curcuma (PDC), konsekuensinya adalah kecernaan nutrisinya secara signifikan (P<0.05) atau sangat signifikan (P<0.01) terendah.  Total digestible nutrient (TDN) dari  PDY dan PDM secara signifikan tinggi (79,89% dan 79,37%) disbanding ransum lainnya, terendah pada PDC (69,94%).  Hal ini menunjukkan bahwa yeast atau ragi dengan konsentrasi 1,8 108cfu/d baik disuplementasikan tunggal atau dikombinasi dengan 2% Curcuma dapat dikatakan sebagai kandungan yang tepat untuk memperbaiki kecernaan nutrisi pada kambing perah dengan laktasi akhir pada penelitian ini.Kata kunci: curcuma, kambing perah,  PUFA-diet, TDN, yeast

Body Index

Stature and weight are important growth and development traits for animals, which also significantly affect the productivity of livestock. Polymorphic adenoma gene 1 (PLAG1) is located in the growth-related quantitative trait nucleotides (QTN), and its variation has been determined to significantly affect the body stature of bovines. This study found that novel 15-bp InDel could significantly influence important growth traits in goats. The frequencies of genotypes of the 15-bp mutation and relationship with core growth traits such as body weight, body height, height at hip cross, chest circumference, hip width and body index were explored in 1581 individuals among 4 Chinese native goat breeds. The most frequent genotypes of Shaanbei white Cashmere goat (SWCG), Inner Mongolia White Cashmere goat (IMCG) and Guanzhong Dairy goat (GZDG) were II genotypes (insertion/insertion), and the frequency of ID genotype (insertion/deletion) was found to be slightly higher than that of II genotype in Hainan Black goat (HNBG), showing that the frequency of the I allele was higher than that of the D allele. In adult goats, there were significant differences between 15-bp variation and body weight, chest circumference and body height traits in SWCG (p < 0.05). Furthermore, the locus was also found to be significantly correlated with the body index of HNBG (p = 0.044) and hip width in GZDG (p = 0.002). In regard to lambs, there were significant differences in height at the hip cross of SWCG (p = 0.036) and hip width in IMWC (p = 0.005). The corresponding results suggest that the 15-bp InDel mutation of PLAG1 is associated with the regulation of important growth characteristics of both adult and lamb of goats, which may serve as efficient molecular markers for goat breeding.

A new type of cow’s milk, called A2 milk, has appeared in the dairy aisles of supermarkets in recent years. Cows’ milk generally contains two major types of beta-casein as A1 and A2 types, although there are 13 genetic variants of β-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I and G. Studies have shown that A1 β-casein may be harmful, and A2 β-casein is a safer choice for human health especially in infant nutrition and health. The A2 cow milk is reportedly easier to digest and better absorb than A1 or other types of milk. The structure of A2 cow’s milk protein is more comparable to human breast milk, as well as milk from goats, sheep and buffalo. Digestion of A1 type milk produces a peptide called β-casomorphin-7 (BCM-7), which is implicated with adverse gastrointestinal effects on milk consumption. In addition, bovine milk contains predominantly αs1-casein and low levels or even absent in αs2-casein, whereby caprine milk has been recommended as an ideal substitute for patients suffering from allergies against cow milk protein or other food sources. Since goat milk contains relatively low levels of αs1-casein or negligible its content, and αs2-casein levels are high in the milk of most dairy goat breeds, it is logical to assume that children with a high milk sensitivity to αs1-casein should tolerate goat milk well. Cow milk protein allergy (CMPA) is considered a common milk digestive and metabolic disorder or allergic disease with various levels of prevalence from 2.5% in children during the first 3 years of life to 12–30% in infants less than 3 months old, and it can go up to even as high as 20% in some countries. CMPA is an IgE-mediated allergy where the body starts to produce IgE antibodies against certain protein (allergens) such as A1 milk and αs1-casein in bovine milk. Studies have shown that ingestion of β-casein A1 milk can cause ischemic heart disease, type-1 diabetes, arteriosclerosis, sudden infant death syndrome, autism, schizophrenia, etc. The knowledge of bovine A2 milk and caprine αs2-casein has been utilized to rescue CMPA patients and other potential disease problems. This knowledge has been genetically applied to milk production in cows or goats or even whole herds of the two species. This practice has happened in California and Ohio, as well as in New Zealand, where this A2 cow milk has been now advanced commercially. In the USA, there have been even promotions of bulls, whose daughters have been tested homozygous for the A2 β-casein protein.
