Abstract:
BACKGROUND: The effects of growth stage (GS) and ensiling were assessed on whole-crop oat's (Avena sativa L. cv. Cantara) chemical composition, silage fermentation quality and in situ ruminal degradability. Oat was harvested and ensiled at six GS: boot, heading, water ripe, early milk, early dough and grain ripe (144, 151, 178, 234, 362 and 512 g kg-1 of dry matter (DM) of whole-crop forage, respectively). RESULTS: GS influenced chemical composition, silage fermentation quality and ruminal degradability of whole-crop oat. Lower DM and higher water-soluble carbohydrates (WSC) contents lead to adequate forage compaction and fermentation at early GS; however, effluent was produced until the dough stage (L and Q; P ? 0.003). Advancing in maturity increased (P < 0.001) crop yield (4.5 to 9.4 t DM ha-1), DM (144 to 512 g kg-1), neutral detergent fibre (NDF; 537 to 571 g kg-1 DM), lignin (44.6 to 71.3 g kg-1 DM) and starch contents (26.4 to 201 g kg-1 DM), and reduced (P < 0.001) crude protein (107 to 60 g kg-1 DM) and WSC (115 to 17.5 g kg-1 DM). DM and NDF ruminal degradability declined with maturity for fresh and ensiled forages (L and Q; P < 0.05). Density and buffering capacity decreased with GS (L and Q; P < 0.001), whereas pH and soluble protein increased (L and Q; P ? 0.004). CONCLUSION: The growth stage of oat influenced the nutritive value and ruminal degradation to a greater extent than ensiling, and thus it can play a paramount role in whole-crop oat silage quality. © 2021 Society of Chemical Industry. © 2021 Society of Chemical Industry.

Abstract: Context. It has been indicated that there might be an antagonism between selection for gastrointestinal nematode resistance and high productivity and feed conversion efficiency in ruminants. Aims. This study aimed to determine whether genetic selection for resistance to gastrointestinal nematodes would alter the feed intake and feed efficiency of sheep with or without an infection of Haemonchus contortus. Methods. Sixty-seven Corriedale lambs (357 14 days old) derived from flocks genetically selected to be resistant
(n = 29) or susceptible (n = 38) to gastrointestinal nematodes (GIN) were evaluated for individual dry-matter intake (DMI), feed conversion ratio (FCR) and residual feed intake (RFI). Considering bodyweight (BW), GIN line and sires, males were allotted to one of three outdoor pens and females to one of two, each pen being equipped with five automated feeding systems and two automatic weighing platforms to record individual feed intake and BW. Feed (lucerne haylage, crude protein 20.5%, metabolisable energy 9.2 MJ/kg DM) and water were offered ad libitum. The experiment was conducted in two periods. First, animals were maintained worm-free (14 days of acclimatisation and 44 days of records) and then, in Period 2 (42 days), animals were artificially infected with 6000 L3 of Haemonchus contortus. Worm egg counts were recorded on Days 9, 23, 27, 30, 42 post-infection. While DMI, FCR, average daily gain and BW were analysed using a generalised linear model including dams age, pen and GIN line as fixed effects, RFI was analysed including only GIN line. Key results. In both periods, GIN line did not have a significant (P > 0.05) effect on DMI, FCR, RFI, average daily gain or BW. Worm egg count was different (P < 0.05) on Day 23 post-infection (Period 2), being higher in susceptible line. Conclusions. The most important finding of this study is that breeding GIN-resistant animals would not have a negative effect on feed conversion efficiency when evaluated as FCR or RFI in 1-year old lambs fed ad libitum with a high-protein diet. Implications. Breeding for resistance to internal nematodes does not affect feed efficiency or productivity. MenosAbstract: Context.
