Diet Intake

Three stargrass silage (SGS)-based diets formulated to contain 20, 26 and 32% neutral detergent fiber (NDF) were compared as to their effect on dry matter intake (DMI) and milk production. Twelve lactating Holstein cows averaging 110 days in milk were arranged in four replications of a 3 x 3 Latin Square design. Treatments did not affect DMI or DMI as percentage of body weight (BW); mean values for these parameters were 15.4 kg/cow/day and 3.06%, respectively. However, cows consuming 32% NDF diet had a tendency toward lower (8.6%) intake of organic matter (OM) as percentage of BW than cows on the 20% NDF diet. Intake of NDF as a percentage of BW increased (P < 0.01) linearly (0.62 to 0.93%) as dietary NDF concentration increased. Milk production averaged 21.0 kg/cow/day and was not affected by dietary treatment. Reducing dietary NDF from 32 to 20% resulted in a reduction (P < 0.01) in milk fat from 3.09 to 2.66%.This reduction resulted in a 1.3 kg/cow/day increase (P < 0.05) in 3.25% fat-corrected milk (3.25% FCM) as the percentage of dietary NDF increased. Gross efficiency of energy (NEL) use for milk production and 3.25% FCM increased linearly with dietary NDF by 9.7 and 17.3%, respectively. Results point out that for mid-lactation cows at the observed level of production, diets lower than 32% NDF will not result in higher DMI and milk production, and will be less efficient in the use of energy for milk production.

Milk Component

Eight Holstein cows were used in a cross-over design to test whether concentrate allocation in an automated milking system (AMS) affects dry matter intake (DMI) and milk production. Cows were fed a high-energy partial mixed ration (HE-PMR) with 0.5 kg of AMS concentrate or a low-energy PMR (LE-PMR) with 5.0 kg of AMS concentrate. The AMS concentrate intake was greater and PMR intake was reduced for LE-PMR than HE-PMR. Milk, fat, and protein yields were not affected by treatment. In a guided-traffic flow barn, providing a PMR with greater energy density increases DMI, but has no effect on milk and milk component yield.

ABSTRAK. Penelitian ini bertujuan untuk mengkaji produksi susu dan komposisi susu sapi Friesian Holstein (FH) yang mendapat suplemen tepung temulawak (Curcuma Xanthorriza Roxb). Materi penelitian menggunakan sapi FH berjumlah 12 ekor. Penelitian menggunakan Rancangan Acak Kelompok dengan 2 perlakuan dan 6 kelompok. Perlakuannya adalah T0 = pakan basal (kontrol), T1 = pakan basal + suplemen temulawak (1% kebutuhan BK). Parameter yang diamati yaitu konsumsi bahan kering, produksi susu dan komposisi susu. Data yang diperoleh di analisis menggunakan sidik ragam, untuk data komposisi susu dilakukan uji lanjut dengan Paired T test. Hasil penelitian menunjukkan bahwa pemberian suplemen temulawak tidak berpengaruh nyata terhadap konsumsi BK, produksi susu dan komposisi susu (laktosa, lemak dan protein). Konsumsi BK T0 sebesar 18,06 kgBK, T1 sebesar 18,15 kgBK, rataan produksi susu T0 sebesar 6,49 liter/hari, T1 sebesar 6,30 liter/hari dan komposisi susu T0 dan T1 secara berturut pada laktosa sebesar 4,58 dan 4,56, kandungan lemak secara berurutan 3,65 dan 3,78 serta kandungan protein secara berurutan sebesar 3,16 dan 3,16. Disimpulkan bahwa pemberian suplemen temulawak 1% kebutuhan BK belum mampu meningkatkan konsumsi bahan kering, produksi dan komposisi susu sapi perah laktasi. (Milk production and milk composition of friesian holstein cows fed with temulawak (Curcuma xanthorriza Roxb) supplement) ABSTRACT. This study aims to examine the milk production and milk composition of friesian holstein cows that fed with temulawak (Curcuma xanthorriza Roxb) supplement. The material of research using 12 FH cows. The study used a randomized block design with 2 treatments and 6 groups. The treatments were T0 = basal feed (control), T1 = basal feed + Curcuma supplement (1% dry matter (DM)). The parameters observed were DM consumption, milk production and milk composition. Data obtained were analyzed using ANOVA, for milk composition data were analyzed using Paired T test. The results showed that the administration of temulawak supplement was not proven significantly towards the dry matter intake, milk production and milk composition (lactose, fat and protein). Dry matter intake T0 group was 18,06 kg, dry matter intake T1 group was 18,15 kg, the average milk production T0 group was 6,49 liters / day, milk production T1 group was 6,30 liters / day. Lactose concentration of group T0 and T1 was 4, 58% and 4,56%, fat concentration of group T0 and T1 was 3,65% and 3,78% and protein concentration of group T0 and T1 was 3,16% and 3,16%. In conclusion, supplements of curcumma 1% DM were not alter dry matter intake, milk production and milk composition.

The objective of this research was to evaluate the chemical composition, selectivity, partial intake, milk production and concentration of urea nitrogen in blood and milk in Gyr x Holstein dairy cows on silvopastoral systems with different densities of Leucaena leucocephala trees. The study was carried out in the Chaco Farm - department of Tolima - Colombia. The treatments were: T1: Cynodon nlemfluensis pasture without trees; T2: C. nlemfluensis + 1264 trees / ha of L. leucocephala; T3: C. nlemfluensis + 4255 trees / ha of L. leucocephala and T4: C. nlemfluensis + 9899 trees / ha of L. leucocephala. Four experimental periods of 32 days were evaluated and 16 F1 (Gy r X Holstein) cows were used. Differences (P <0.05) were observed in relation to the dry matter of both C. nlemfluensis and L. leucocephala. There was high selectivity for grass (P <0.05). The dry matter intake decreased with the increase in the density of L. leucocephala trees in period 3, in the other periods no differences were observed (P> 0.05). As the density of L. leucocephala trees increased, the values of urea nitrogen in blood and milk increased (P <0.05). Milk production was not altered by treatments. It is concluded that F1 (Gyr X Holstein) cows in silvopastoral systems have a high selectivity and partial intake of grass, and higher levels of blood and milk urea nitrogen.

Two Stages

We evaluated heifer post-weaning residual feed intake (RFI) classification and cow age on dry matter intake (DMI) at two stages of production. Fifty-nine non-lactating, pregnant, (Study 1) and fifty-four lactating, non-pregnant (Study 2) commercial black Angus beef cows were grouped by age and RFI. Free-choice, hay pellets were fed in a GrowSafe feeding system. In Study 1, cow DMI (kg/d) and intake rate (g/min) displayed a cow age effect (p < 0.01) with an increase in DMI and intake rate with increasing cow age. In Study 2, cow DMI (kg/d) and intake rate (g/min) displayed a cow age effect (p < 0.02) with an increase in DMI and intake rate with increasing cow age. Milk production displayed a cow age × RFI interaction (p < 0.01) where both 5–6-year-old and 8–9-year-old low RFI cows produced more milk than high RFI cows. For both studies, intake and intake behavior were not influenced by RFI (p ≥ 0.16) or cow age × RFI interaction (p ≥ 0.21). In summary, heifer’s post-weaning RFI had minimal effects on beef cattle DMI or intake behavior, however, some differences were observed in milk production.

Whole barley was treated with sodium hydroxide (NaOH) in laboratory trials. Dry matter disappearance from nylon bags in the rumen of whole barley treated with 2.5, 3.5, or 4.9% NaOH for 30 h was 59.6, 72.4, and 93.0%, respectively, compared with 82.2% for untreated ground barley. In a subsequent lactation trial, 24 Holstein cows (eight per treatment) were fed high moisture ground ear corn, high moisture rolled barley or high moisture whole barley treated with 3.5% NaOH. Milk persistencies tended to be greater for cows fed high moisture rolled barley, next for ground ear corn and least for NaOH-treated barley. Milk composition was similar for all treatments. Dry matter intake was greatest for cows fed ground ear corn and lower for those fed the barley diets. Alpha-linked glucose and pH of feces were similar for cows fed ground ear corn and high moisture rolled barley diets, but fecal pH was lower and alpha-linked glucose concentrations three times greater for NaOH-treated barley. Digestibility percents of dry matter, acid detergent fiber and nitrogen were 61.4, 25.3, 64.7 for ground ear corn; 64.4, 38.0, 67.1 for high moisture rolled barley; and 56.8, 43.2, 54.8 for NaOH-treated barley, respectively. Rumen grain turnover estimated by excretion of ytterbium in feces was greatest for NaOH-treated barley (9.09%/h), intermediate for ground ear corn (6.10%/h) and lowest for high moisture rolled barley (4.93%/h).
