Supplementation with 1.5% urea increased (P < 0.01) the dry matter intake by crossbred ewes fed oats (7.2% crude protein) during late pregnancy and lactation. The increase in intake by the ewes during lactation resulted in a higher weaning weight of single lambs (10.2 vs 18.6 kg, P < 0.01 ),and enabled twin lambs to attain a weaning weight of 12.9 kg. Unsupplemented ewes suckling twin lambs were removed from the experiment 3 weeks after lambing when their mean liveweight was only 35.3 kg compared with 51.0 kg 6 weeks before lambing. Additional increases in dry matter intake of the ewes and liveweight of the lambs at 6 weeks of age were obtained by adding iso-nitrogenous supplements of commercial protein pellets or lucerne chaff. Fewer (P < 0.05) twin lambs died within the first 7 days when the oats were supplemented with lucerne chaff. The results indicate that supplementation of low protein oats with urea increased the intake of crossbred ewes suckling single or twin lambs and the increase was particularly important for ewes with twin lambs. Additional benefits achieved by supplementing with protein pellets or lucerne chaff were not of practical or economic significance.

Manchega (MN) and Lacaune (LC) are two semi-coarse-wooled dairy breeds with similar size but different milk yield, the latter producing twice as much milk as the former (Pérez, 1997). The aim of this experiment was to compare, under the same feed conditions, dry matter intake and performance in late pregnancy and lactation and digestive pools of these two breeds.Twenty-four ewes, 12 per breed, were used in three different periods: late pregnancy (8 weeks), rearing (5 weeks) and milking (7 weeks). At lambing, average body weight was 74.4 vs 78.5 kg, for LC and MN, respectively. Dry matter intake (DMI), apparent dry matter digestibility (DMD), body condition score (BCS) and milk yield (MY) standardized according to Bocquier et al. (1993) were recorded.

Four Levels

Crossbred lambs [Poll Dorset x (Border Leicester x Merino)] were offered pasture hay (12% crude protein, 55.3% dry matter digestibility) ad libitum and supplemented with four levels of cereal (oats) or legume (peas) grains; 0, 250, or 500 g/head.d, or ad libitum in individual pens or in groups of 30 (feedlot). Increasing the level of supplementation of peas of the individually fed lambs from 0 to ad libitum increased total dry matter intake from 22 1 to 1041 g/head.d (P< 0.01), liveweight gain from - 70 to 263 g/d and wool growth from 13.1 to 38.3 mg clean wool/cm2. The corresponding results for oats were: total intake from 22 1 to 3 15 g/head.d (P> 0.05), liveweight gain from -70 to 52 g/d (P < 0.01) and wool growth from 13.1 to 15.2 mg clean wool/cm2 (P> 0.05). The intake of hay by the lambs supplemented with peas was not depressed until the peas were offered ad libitum but there was a significant decrease in the intake of hay (P< 0.01) at the lowest level of supplementation of oats. A similar pattern of response for total intake, intake of hay and liveweight gain was observed with the feedlot lambs.

SUMMARY1. Sixteen foods, ranging in crude protein content from approximately 2·6 to 10·0%, were each offered ad lib. to four wether sheep. Dry-matter intake, N content and apparent digestibility of dry matter for each food were determined.2. Voluntary intake of food dry matter was closely related to N content.3. Slow fermentation in the reticulo-rumen and the associated slow rate of passage through the digestive tract may control the intake of low protein foods by sheep.4. There was evidence of adaptation of sheep to low protein diets as the trials progressed and significant differences occurred in voluntary food consumption between sheep.

Randomized Experimental Design

The aim of this study was to evaluate the performance of crossbred Holstein × Zebu steers fed on the diets containing sugarcane in natura or ensiled with two levels of concentrate (30% and 70%). A total of 32 males of 394 kg of body weight were used in a completely randomized experimental design with four treatments and seven repetitions. The animals reported a high dry matter intake (DMI) (P < 0.05) when fed on the high concentrate levels. The increase in concentrate levels resulted in an approximately 25% to 60% higher DMI as compared to the lowest level offered by silage-based diets and sugarcane in natura. The highest apparent digestibility coefficients of dry matter were observed in the diets based on sugarcane in natura (P < 0.05). The sugarcane based diets also affected (P > 0.05) the digestibility of organic matter, neutral detergent fiber, crude protein, ether extract, and non-fiber carbohydrates. There were no differences (P > 0.05) between the diets for average daily weight gain, carcass dressing, carcass gain, and feed conversion. The diets based on sugarcane in nature or ensiled with 30% and 70% concentrates do not influence the performance of crossbred Holstein × Zebu cattle.

The Relationship

AbstractA nutritional hypothesis for the occurrence of the periparturient relaxation of immunity (PPRI) to gastrointestinal nematodes was tested within the bounds of a nutrient partitioning framework. It was hypothesized that at times of a scarce supply of metabolizable protein (MP), an increase in MP supply or a reduction in MP demand (having singles instead of twins) should lower the extent of PPRI in sheep. Twenty-one single- and 21 twin-bearing and -rearing Finn-Dorset ewes, 2 to 7 years old, and repeatedly infected withTeladorsagia circumcincta, were given one of three pelleted foods (no. = 7). The foods were formulated to supply 0·8 (L), 1·0 (M) and 1·2 (H) times the MP requirements during lactation, and were offeredad libitumfrom d–21to d35(d0 is day of parturition). Faecal egg counts (FEC) were assessed twice weekly as an indicator for host resistance. Dry-matter intake (DMI) during late pregnancy was higher than expected, and MP supply did not limit performance at this stage. In accordance with the hypothesis, there were no indications of a breakdown of immunity toT. circumcinctaduring late pregnancy. DMI during lactation did not differ between the single- and twin-rearing ewes. Calculated milk production was lower for the L than for the M and H ewes, especially for the twin-rearing ewes. A temporarily elevated FEC was observed during the first few days in lactation, which was probably mainly due to changes in faecal output rather than to PPRI. The FEC returned to low, late pregnancy levels at d12and remained low for the single- but not for the twin-rearing ewes (P< 0·001). Overall, the L ewes had higher FEC than the M and H ewes from d19onwards; this effect was more pronounced for the twin- than for the single-rearing ewes. It was postulated that DMI achieved overcame MP scarcity and thus prevented breakdown in immunity in the single-rearing ewes. The data support the view that, at times of MP scarcity, an increase in MP supply and reduction in MP demand can lower the extent of the breakdown in immunity towardsT. circumcincta.

Abstract. This study was aimed to examine the excretion of urinary creatinine in young and mature Kacang goat bucks under different feeding levels. This study used 16 Kacang goat bucks consisting of 2 groups of age, i.e. eight young bucks (aged 6-7 months, weighed 12.75±2.68 kg) and 8 mature bucks (age 9-12 months, weighed 17.34±3.32 kg). The bucks were fed pelleted complete feed containing 78.82% dry matter (DM), 18.80% crude protein (CP), and 76.29% total digestible nutrients (TDN). The bucks were allocated into a 2x2 nested design with four replications. The treatment was the amount of  2.24% dry matter intake  (T1) and 4.48% of body weight (BW) (T2) for the young goat, while the mature buck was 1.87% and 3.74%, respectively. The results showed that DM, CP and TDN intake were significant different across ages and highly significantly different between feeding levels. Changes of urinary creatinine from week 0–12 showed no differences in the age group (142 mg/dl) and feeding level (143 mg/dl). Conclusively, age and feed level affected body weight, feed intake and creatinine excretion of Kacang Goat.  The more body weight gain (age) and feed level, the more urinal creatinine excretion in male Kacang goat. Key words: Kacang goat, ages, feeding level, and creatinine Abstrak. Penelitian ini bertujuan untuk mengkaji kadar kreatinin pada kambing Kacang muda dan dewasa dengan jumlah pemberian pakan yang berbeda. Materi berupa 16 ekor kambing Kacang jantan, terdiri dari 8 ekor umur muda (6-7 bulan) dan 8 ekor umur dewasa (9-12 bulan). Pakan komplit yang diberikan memiliki kandungan bahan kering (BK) 78,82%, protein kasar (PK) 18,80%, dan total digestible nutrients (TDN) 76,29%. Rancangan penelitian ini adalah pola tersarang 2x2 dengan 4 ulangan. Perlakuan pakan berupa jumlah BK pakan yang diberikan yaitu 2,24% bobot badan (BB) (T1) dan 4,48% BB (T2) untuk kambing muda, sedangkan kambing dewasa sebesar 1,87% BB (T1) dan 3,74% BB (T2). Hasil penelitian menunjukkan bahwa konsumsi BK, PK dan TDN berbeda nyata pada kelompok umur dan berbeda sangat nyata pada perlakuan pakan. Kadar kreatinin pada minggu ke 0-6 tidak berbeda nyata, namun pada minggu ke 12 berbeda nyata baik kelompok umur maupun akibat perlakuan pakan. Perubahan kadar kreatinin dari minggu ke 0-12 menunjukkan perbedaan yang tidak nyata pada kelompok umur dan perlakuan pakan. Kesimpulan dari penelitian ini adalah kadar kreatinin semakin meningkat dengan semakin meningkatnya bobot badan (umur) dan pakan ternak. Kata kunci : kambing Kacang, umur, level pakan, dan kreatinin

Low Nitrogen

In each of two experiments, single infusions of casein administered to sheep per duodenum produced substantial and rapid increases in voluntary intake of chaffed oaten hay diets of low nitrogen content (0.62–0.70% nitrogen). The effect commenced within 16 hr of completion of the infusion, and occurred before any observed change in the rate of cellulose digestion in the rumen. When urea was infused per duodenum at the same level of nitrogen as with the casein, an increase in intake occurred on the day following infusion in one experiment. In a second experiment no such response occurred. Faster rates of cellulose digestion were observed on the day of infusion, apparently due to recycling of nitrogen to the rumen. Of the 10 g of nitrogen infused, 7.4 g of casein nitrogen and 5 g of urea nitrogen were retained. Propionate, infused in an attempt to reproduce the gluconeogenic properties of casein, did not have any major effect on daily dry matter intake, although it caused a depression in intake during the period of infusion in one experiment. Results are discussed in relation to the possible mechanism of response to the protein supplement. The possibility is suggested that the protein status of the animal is a component of a chemoregulatory mechanism governing the intake of low nitrogen diets by sheep.

ABSTRACTWheat straw treated with 35 g NaOH per kg was offered to male calves at three levels: 300 (A), 500 (B), and 700 (C) g/kg diet, in a metabolism trial and in a feeding trial. In the former the wheat straw was offered either neutralized with HC1 (N) or unneutralized (U), in six subtreatments (AN, BN, CN, AU, BU and CU) in a 3 × 2 factorial design to a total of 24 calves. Dry-matter intake per kg W0·73was 123, 108, 104, 122, 105 and 91 g/day, and the digestibility of the organic matter of the straw was 0·388, 0·616, 0·629, 0·385, 0·528 and 0·544 respectively. The apparent digestibility of the crude protein of the straw was negative. Nitrogen retention per kg W0·73was 0·91, 0·58, 0·52, 0·97, 0·57 and 0·50 g/day, respectively.In the feeding trial, unneutralized, NaOH-treated wheat straw was offered to a total of 84 calves for 100 days at the above three levels with two protein levels: standard, 120 g/kg (S) and high, 140 g/kg (H), in six subtreatments (AS, BS, CS, AH, BH and CH) in a 3 × 2 factorial design. The concentrates were pelleted. From day 101 to slaughter all the calves were offered one finishing diet.Level of protein had no effect on performance. Increasing the levels of straw in the first 100 days sharply reduced average daily gains; these were 1 074, 825 and 583 g, respectively. However, the respective average daily gains on the finishing diet were 1 131, 1 272 and 1 316 g, indicating a considerable amount of compensatory growth.
